The Effects of Extramedullary Reduction in Unstable Intertrochanteric Fracture: A Biomechanical Study Using Cadaver Bone: Young Chang Park, Soon Phil Yoon, Kyu Hyun Yang; J Korean Fract Soc 2018;31(3):79-86. Published online July 31, 2018; DOI: https://doi.org/10.12671/jkfs.2018.31.3.79

PURPOSE
To prevent excessive sliding and subsequent fixation failures in unstable intertrochanteric fractures with posteromedial comminution, extramedullary reduction through overlapping of the anteromedial cortices of both proximal and distal fragments as a buttress has been introduced. The purpose of this study was to compare the biomechanical properties between two reduction methods-intramedullary reduction and extramedullary reduction-in treating unstable intertrochanteric fractures with posteromedial comminution (AO/OTA classification 31-A2.2).
MATERIALS AND METHODS
Eight pairs of frozen human cadaveric femora were used. The femora of each pair were randomly assigned to one of two groups: the intramedullary reduction group or the extramedullary reduction group. A single axial load-destruction test was conducted after cephalomedullary nailing. Axial stiffness, maximum load to failure, and energy absorbed to failure were compared between the two groups. Moreover, the pattern of mechanical failure was identified.
RESULTS
The mean axial stiffness in the extramedullary reduction group was 27.3% higher than that in the intramedullary reduction group (422.7 N/mm vs. 332.0 N/mm, p=0.017). Additionally, compared with the intramedullary reduction group, the mean maximum load to failure and mean energy absorbed to failure in the extramedullary group were 44.9% and 89.6% higher, respectively (2,848.7 N vs. 1,966.5 N, p=0.012 and 27,969.9 NÂ·mm vs. 14,751.0 NÂ·mm, p=0.012, respectively). In the intramedullary reduction group, the mechanical failure patterns were all sliding and varus deformities. In the extramedullary reduction group, sliding and varus deformities after external rotation were noted in 3 specimens, sliding and varus deformities after internal rotation were noted in 3 specimens, and medial slippage was noted in 2 specimens.
CONCLUSION
In unstable intertrochanteric fractures with posteromedial comminution, the biomechanical properties of extramedullary reduction are superior to those of intramedullary reduction. Anteromedial cortex could be the proper buttress, despite a comminuted posteromedial cortex. It could help enhance the stability of the bone-nail construct.

Fixation of the Greater Trochanter in Arthroplasty for Unstable Intertrochnateric Fracture: Dong Hyeok Choi, Ju Yeong Heo, Young Jae Jang, Young Yool Chung; J Korean Fract Soc 2014;27(1):58-64. Published online January 31, 2014; DOI: https://doi.org/10.12671/jkfs.2014.27.1.58

Abstract PDF

PURPOSE
We classified fractures of the greater trochanter (GT) and evaluated fracture fragment stability according to GT type.
MATERIALS AND METHODS
A total of 43 patients with an unstable intertrochanteric fracture treated between January 2007 and July 2009 with bipolar hemiarthroplasty were included in this study. GT fractures were classified as type A, B, C, or D and fixed using either cerclage wiring alone, cerclage wiring and non-absorbable suture or a greater trochanteric reattachment (GTR) plate.
RESULTS
Type A fractures were fixed using cerclage wiring with non-absorbable suture in two cases, cerclage wiring in six cases and GTR plate in seven cases. Failure occurred in three cases of type A fractures treated with cerclage wiring alone. A total of 11 type B fractures were fixed with cerclage wiring (7), cerclage wiring and non-absorbable suture (3) and GTR plate (1). There was no failure of type B fractures. Type C fractures were fixed using cerclage wiring with non-absorbable suture in one case and GTR plate in three. There was no fixation in three cases. Of 10 type D fractures, six were treated with cerclage wiring and one with GTR plate. Fixation was not performed in three patients. There was no failure in type C and D type fractures.
CONCLUSION
Fracture fragment stability differed according to fracture types. Cerclage wiring alone was insufficient to fix type A fractures, so type A fracture required a stronger fixation method.

Unstable Intertrochanteric Fracture Treated with ITST: A Comparative Study between Groups with and without Comminution of Greater Trochanter: Kyung Sub Song, Sang Ho Lee, Seong Hun Jeong, Su Keon Lee, Sung Ha Hong; J Korean Fract Soc 2014;27(1):36-41. Published online January 31, 2014; DOI: https://doi.org/10.12671/jkfs.2014.27.1.36

Abstract PDF: PURPOSE
To evaluate whether the radiological and clinical results of treatment with intertrochanteric/subtrochanteric (ITST) nail on unstable intertrochanteric fractures are combined with comminution of the greater trochanter or not.
MATERIALS AND METHODS
We reviewed the results on 210 cases of unstable intertrochanteric fractures (grouped 88 patients with comminution of greater trochanter [GT] and 122 patients without comminution of GT) treated with ITST nail from January 2007 to October 2011, which was to be followed-up for more than 12 months.
RESULTS
The mean union time was 15.2 weeks in the study group (combined with comminution of GT). The mean union time was 14.7 weeks in control group (no comminution of GT). The lag screw sliding was 8.7 mm in the study group and 7.2 mm in the control group. Changes of neck-shaft angle was 4.2degrees in study group and 4.1degrees in control group. Tip-apex distance was 17.4 mm in study group and 16.4 mm in control group. The complications were 4 cases in each study group and control group. The clinical results checked by Skovron recovery scores decreased similarly in both groups, 73.7% in study group and 76.5% in control group. There were no significant differences in both groups according to radiological and clinical results.
CONCLUSION
The comminution of great trochanter does not affect on the radiological and clinical results when using the ITST nail of unstable intertrochanteric fractures.

The Efficiency of Additional Fixation of the Alternative Bone Substitute in Unstable Intertrochanteric Fractures of Femur Treated with Gamma Nail: Jong Oh Kim, Young One Ko, Mi Hyun Song; J Korean Fract Soc 2011;24(1):1-6. Published online January 31, 2011; DOI: https://doi.org/10.12671/jkfs.2011.24.1.1

Abstract PDF: PURPOSE
To evaluate the efficiency of additional fixation of the alternative bone substitute in unstable intertrochanteric fractures treated with gamma nail and alternative bone substitute and only with gamma nail.
MATERIALS AND METHODS
Radiologic comparison was done between forty-four patients of unstable intertrochanteric fracture (AO type A2.2, A2.3) during six months. The patients were divided into two groups, a group treated with gamma nail and alternative bone substitute (22 patients, group 1) and another group treated only with gamma nail (22 patients, group 2). Postoperative reduction status, Cleveland index, Tip-apex distance and complications during the follow-up period was compared. Lag screw slippage and femoral neck-shaft angle change were measured between two groups.
RESULTS
No significant difference of reduction status, Cleveland index and Tip-apex distance was found. In group II, there was a 1 more case of cutting-out of the lag screw, but also there was a significant difference. Lesser change in lag screw slippage and neck-shaft angle change was investigated.
CONCLUSION
As there are lesser lag screw slippage and neck-shaft angle change, alternative bone substitutes applied in unstable intertrochanteric fractures seems to be useful in maintaining reduction and preventing failure of internal fixation when proper reduction and screw insertion is performed.

Cementless Bipolar Hemiarthroplasty for Treating Intertrochanteric Fracture in Elderly Patients: Han Jun Lee, Jong Won Kim, Jae Sung Lee, Jae June Yang, Woo Young Hwang; J Korean Fract Soc 2010;23(3):276-281. Published online July 31, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.3.276

Abstract PDF

PURPOSE
To evaluate clinicoradiological outcomes after cementless bipoloar hemiarthroplasty in elderly patients with femoral intertrochanteric fractures.
MATERIALS AND METHODS
From March 2006 to February 2008, 28 patients-all in patients greater than 80 years of age, classified unstable intertrochanteric fractures in Evans classification-were followed for more than 1 year. 24 patients were women and 4 patients were men. The mean age of the patients was 84.6 years, the mean follow-up period was 16.3 months. Harris hip score, postoperative inguinal and thigh pain, Parker and Palmer mobility score were analyzed clinically. The radiological results were assessed using various radiological indicies including bone-union, fit and alignment change of femoral stem and vertical subsidence.
RESULTS
The average Harris hip score was 82.9, Parker and Palmer mobility score preoperative 8.0 changed to 5.2 postoperatively. More than moderate pain was presented in 1 case. There were no cases of varus deformity or osteolysis. All stems were stable without significant alignment change or subsidence except 1 case of periprosthetic fracture. There were no dislocation, thromboembolism, death during operation or hospital days.
CONCLUSION
In elderly patients, cementless bipolar hemiarthroplasty is good treatment method of unstable intertrochanteric fracture and short-term clinicoradiological outcomes proved to be satisfactory.

Proximal Femoral Nail Antirotation versus Compression Hip Screw with Trochanter Stabilizing Plate for Unstable Intertrochanteric Hip Fractures: Jae Young Rho, Sang Bum Kim, Youn Moo Heo, Seong Jin Cho, Dong Sik Chae, Woo Suk Lee; J Korean Fract Soc 2010;23(2):161-166. Published online April 30, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.2.161

Abstract PDF

PURPOSE
To analyze and compare the clinical and radiologic results of treatments in unstable intertrochanteric fractures of the femur with proximal femoral nail antirotation (PFNA) and compression hip screw with trochanter stabilizing plate (CHS with TSP).
MATERIALS AND METHODS
We retrospectively reviewed the results of 66 cases of unstable intertrochanteric fractures of the femur treated with PFNA (Group I) and CHS with TSP (Group II) which could be followed up for minimum a year. We evaluated several comparative factors such as operation time, blood loss, time to bone union, changes in neck-shaft angle, sliding of screw (or blade), complications, postoperative pain, social-function score of Jensen, and mobility score of Parker and Palmer.
RESULTS
Group I showed shorter operation time and less blood loss with significance than group II (p<0.05), but there were no differences between the groups in the mean time to bone union, changes in neck-shaft angle, sliding of screw (or blade), complications, postoperative pain, and social-function score of Jensen (p>0.05). Two cases of cutting out of the blade through the femoral head were found in group I. One case of cutting out of the screw, one case of the breakage of the plate, and loosening of the plate were found in group II as complications.
CONCLUSION
We think that there were no significant differences between PFNA and CHS with TSP in view point of radiologic and clinical outcomes in unstable intertrochanteric fractures of the femur, but PFNA is less invasive device than CHS with TSP, therefore it may be useful device in elderly patients.

Published online July 31, 2009; DOI: https://doi.org/10.12671/jkfs.2009.22.3.131

Abstract PDF

PURPOSE
To evaluate between DHS and ITST nail (2nd generation) on the treatment of unstable femur intertrochanteric fracture in patients over 70 years old.
MATERIALS AND METHODS
61 cases of unstable intertrochanteric fracture (grouped 37 patients with DHS and 24 patients with ITST) who were taken the operation from Mar. 2003 to Sep. 2007 were analysed regarding to union time, sliding length of lag screws, operation time, blood loss, postoperative complications and functional recovery score by Skovron.
RESULTS
The mean union time was 14.7 weeks in study group (ITST). The mean union time was 16.2 weeks in control group (DHS). The lag screw slidings were 7.2 mm in study group and 8.7 mm in control group. The operation times were 57.9 min in study group and 76.9 min in control group. The amount of blood loss were 67.7 ml in study group and 227.4 ml in control group. The complications were 4 cases in study group and 4 cases in control group. The Skovron recovery scores were 76.5% in study group and 73.7% in control group.
CONCLUSION
From a practical point of short operation time, less amount of bleeding and less complication, author think that the ITST nail is useful implant for treatment of unstable femur intertrochanteric fracture in patient of old age.

Comparison between Results of Internal Fixation and Hemiarthroplasty in Unstable Intertrochanter Fracture of Osteoporotic Bone: Haw Jae Jung, Jae Yeol Choi, Hun Kyu Shin, Eugene Kim, Se Jin Park, Yong Taek Lee, Gwang Sin Kim, Jong Min Kim; J Korean Fract Soc 2007;20(4):291-296. Published online October 31, 2007; DOI: https://doi.org/10.12671/jkfs.2007.20.4.291

Abstract PDF

PURPOSE
To perform comparative analysis between the results of internal fixation and hemiarthroplasty in unstable intertrochanteric fracture of osteoporotic bone.
MATERIALS AND METHODS
From February 2003 to February 2006, 36 patients treated surgically for unstable intertrochanteric fractures were evaluated. The patient's age was older than 70 year old; the T-score of preoperative bone mineral density (BMD) was lower than -3.0; they were followed up for more than 1 year. The patient were divided into two groups. One group was treated with dynamic hip screw or proximal femoral nail (Group A, 23 cases), and the other group was treated with bipolar hemiarthroplasty (Group B, 13 cases). The two groups were compared in terms of hip joint function using Clawson classification and radiologically.
RESULTS
Nonunion and fixation failure happened in 6 cases (26%) of gruop A. However, all patients in group B showed stable maintenance of implant. Recovery of hip joint function was found in 13 cases (43%) of group A, whereas 12 cases (93%) of group B recovered.
CONCLUSION
Nonunion and failure of fixation happened more frequently in internal fixation than bipolar hemiarthroplasty, and the postoperative hip joint function was better in bipolar hemiarthroplasty than internal fixation. Therefore, bipolar hemiarthroplasty might be better operative treatment for unstable intertrochanteric fracture of osteoporotic bone.

Treatment of Stable Intertrochanteric Fractures Using a Short Side Plate Dynamic Hip Screw: Chong Kwan Kim, Jin Woo Jin, Sung Won Jung, Wan Sub Kwak, Jae Il Jo, Woo Sik Kim; J Korean Fract Soc 2006;19(3):309-313. Published online July 31, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.3.309

Abstract: PURPOSE
To evaluate the usefulness of a 2 holes side plate dynamic hip screw for the treatment of stable intertrochanteric fracture of the femur.
MATERIALS AND METHODS
Between January 2000 and September 2004, 46 patients with intertrochanteric fracture of the femur were treated with 2 hole side plate dynamic hip screw (Group 1, 25 cases) or 4 hole side plate dynamic hip screw (Group 2, 21 cases). The mean age of the patient was 70 years, with a mean follow-up duration of 13 months. The time for operation, surgical incision length, blood loss, time for union, the sliding distance, change in the femoral neck-shaft angle and patient's walking ability were evaluated.
RESULTS
The mean operation time and mean incision length were shortened, and mean blood loss was decreased in Group 1 (p<0.01). There was no statistical difference in the union time, the mean change in the femoral neck-shaft angle and the mean sliding distance of the lag screw at the last follow-up. The mean mobility score of the Parker and Palmer was 8.0 points before the fracture and 7.2 points at the last follow-up.
CONCLUSION
Two-hole side plate dynamic hip screw is a useful device, in terms of the operation time, morbidity of operation site, satisfactory union rate and functional recovery of the patient in treatment of elderly patients with stable intertrochanteric fractures of the femur.

The Treatment of Unstable Intertrochanter Fracutures of Femur: Comparison between Proximal Femoral Nail and Dynamic Hip Screw: Kyun Chul Kim, Hun Kyu Shin, Kyung Mo Son, Chun Seok Ko; J Korean Fract Soc 2005;18(4):369-374. Published online October 31, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.4.369

Abstract PDF

PURPOSE
To analyze the results between PFN (Proximal Femoral Nail) and DHS (Dynamic Hip Screw) on the operative treatment of unstable intertrochanteric fractures retrospectively.
MATERIALS AND METHODS
35 cases of unstable intertrochanteric fractures (grouped 24 patients with DHS and 11 patients with PFN) who were taken the operations from Jan. 2001 to Mar. 2002 were analysed regarding to union state, union time, operation time, sliding length of lag screws, blood loss, postoperative complications and functional recovery scores by Sk?vron with ANOVA and multivariate linear regression.
RESULTS
The means of union time were 17.9 weeks (DHS) and 17.0 weeks (PFN), sliding length of lag screws were 3.9 mm (DHS) and 2.1 mm (PFN), perioperative blood losses were 743 cc (DHS) and 736 cc (PFN), operation time were 93.4 minutes (DHS) and 102 minutes (PFN), and the functional recovery scores by Sk?vron were 71.8% (DHS) and 76.8% (PFN), respectively. The results of our study indicate that there were not statistically significant differences between PFN and DHS groups in treatment of unstable intertrochanteric fractures (p>0.05). But, there was less sliding of lag screws in PFN group in statistical significance (p<0.05).
CONCLUSION
Authors think that PFN is one of the useful implants in treating unstable intertrochanteric fractures of the femur in regarding to sliding.

Published online October 31, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.4.359

Abstract PDF

PURPOSE
To analyze the effect of treatment of unstable intertrochanteric fractures with dynamic hip screw and additional trochanter stabilizing plate.
MATERIALS AND METHODS
Among twenty three cases of unstable intertrochanteric fractures treated with DHS and additional TSP between January 2002 to December 2004, seventeen cases over sixty years old were reviewed with minimal follow up of one year. We analyzed the type of fracture by AO classification, the age of patient, sex, the cause of trauma in seventeen cases. We evaluated the lag screw slippage, the change of neck-shaft angle and lateral displacement of greater trochanter, the period of union by comparison of last follow up radiographs with immediate postoperative radiographs. The fixation failure is defined that displacement of lag screw tip is more than 3 mm or cut out of the screw from the femoral head.
RESULTS
The period of union was average 12.8 weeks. The lag screw slippage was average 8.22 mm. The change of neck-shaft angle was average 2.66 degree. No lateralization of greater trochanter was noted in twelve cases, but five cases showed average 0.8 mm (range: 0.5~1 mm) of lateral displacement of greater trochanter. There was not fixation failure.
CONCLUSION
In unstable intertrochanteric fracture, the addition of a TSP to the dynamic hip screw can decrease a change of neck shaft angle, a lag screw slippage, and prevent lateral displacement of greater trochanter.

In unstable femoral trochanteric fracture, we usually used transversing K-wires through the lesser trochanter to achieve an anatomical reduction, and using sliding hip screws. However, in patients with comminuted lesser trochanter or osteoporosis, an intrusion of the wire into the lesser trochanter and/or iatrogenic intertrochanteric fractures were often resulted. Those who were not familiar with a technique of puncturing two holes through the lesser trochanter might have had to face some difficulties. In order to overcome aforementioned drawbacks, the authors had quite satisfactory results by employing the method of passing each of two wires above and below the iliopsoas muscle, and they were twisted posteriorly and then anteriorly; and finally they were pulled together posteriorly. Through this technique, both firm fixation of the lesser trochanter and more stable bony union were obtained.

Fixation Failure of Unstable Intertrochanteric Fracture of the Femur Using Compression Hip Screw: Sang Won Park, Soon Hyuck Lee, Jong Ryoon Baek, Sung Jun Park, Jong Won Chung; J Korean Fract Soc 2005;18(1):1-5. Published online January 31, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.1.1

Abstract PDF: PURPOSE
To investigate the factors which influence on the fixation failure after the compression hip screw fixation for unstable intertrochanteric fractures.
MATERIALS AND METHODS
Eighty-two patients of unstable intertrochanteric fracture of A2 and A3 type who had underwent operation with compression hip screw were evaluated at least 1 year follow-up in regard to the age, degree of osteoporosis, fracture type, diastasis of fragment, sliding of lag screw, position of lag screw and status of reduction.
RESULTS
73 patients out of 82 patients had the union and 9 patients showed fixation failure. The results of fixation failure were 6 cases of migration of lag screw and 3 cases of cut-out of lag screw. There were statistically significant correlations between fixation failure and A2.3 and A3 type. The fixation failure group showed increased medial migration of medial cortex of proximal and distal fragment, which is significantly correlated with fixation failure. There were little statistical significant correlations between age, degree of osteoporosis, status of reduction, position of lag screw, sliding of lag screw and fixation failure.
CONCLUSION
Another alternative fixation method and technique have to be considered for unstable A2-3 or A3 type because compression hip screw fixation only is very insufficient with high failure rate.

Common Modes of Fixation Failure with a Sliding Hip Screw encountered Unstable Intertrochanteric Fracture: Byung Soon Kim, Duck Yun Cho, Hyung Ku Yoon, Dong Eun Sin, Soo Hong Han, Jae Hwa Kim, Dong Jun Kim; J Korean Soc Fract 2003;16(1):15-21. Published online January 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.1.15

Abstract PDF

The purpose of this study was to evaluate the common modes of fixation failure in unstable intertrochanteric fractures , related risk factors and the prevention of fixation failure. Between 1995 and 2001, 44 patients who had sustained an unstable intertrochanteric fractures were assigned to be treated with a sliding hip screw. Men in 14 cases ( 32% ), women in 30 cases ( 68% ) , the average age at the operation was 65(22-90) years and the average duration of follow up was 12(8-22) months. We classified the fracture patterns with Evans system and used Singh 's index for osteoporosis. And we examined the common modes of fixation failure with postoperative X-ray. The fixation failure in unstable intertrochanteric fracture was 8 cases (18.2 % ); varus collapse of the proximal fragment with cutout of the lag screw was 3 cases (6.8%), varus collapse of the proximal fragment with excessive sliding of the lag screw was 4 cases (9.1%) and loss of fixation of the plate-holding screws was 1 case (2.3%). The authors think that inadequate anatomical reduction of comminuted posteromedial fragment and severity of osteoporosis are main causes of fixation failure. During operation for unstable intertrochanteric fractures, the most important point is accurate reduction of posteromedial fragment and the intramedullary hip screw like proximal femoral nail ( PFN ) may be considered to avoid fracture of lateral cortex that enter the lag screw, causing fixation failure.

Effect of Trochanter Stabilizing Plate in Unstable Intertrochanteric Fracture: Youn Soo Park, Kye Young Han, Hyung Gun Kim; J Korean Soc Fract 2000;13(4):779-787. Published online October 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.4.779

Abstract PDF

PURPOSE
The purpose of this study is to investigate the effectiveness of trochanter stabilizing plate (TSP) with compression hip screw(CHS) on the reduction stability, fracture union and sliding of lag screw in unstable intertrochanteric fracture. MATERIAL AND METHOD: From October 1997 to March 1999, 32 cases(group 1) and 20 cases(group 2) who could be followed for more than 1 year were treated with TSP (group 2) and CHS only (group 1) due to unstable intertrochanteric fractures. And two groups were compared clinically and radiologically.
RESULTS
Operation time was longer in group 2 and hospital stay was longer in group 1. Preoperative functions were better in group 1(7.00 points) than in group 2(6.47 points). When postop. function was compared with preop. function, group 1 showed differences on the three months follow-up and six months follow-up. Whereas group 2 only showed difference on the three months follow-up but not on the six months follow-up. There was no difference in the incidence of lag screw sliding. However, there were differences in the extent of sliding between group 1(ave.4.88mm) and group 2(ave.2.88mm) with three months follow-up and six months follow-up (group 1: ave 5.42mm and group 2: ave. 3.03mm). There was a significant difference between group 1(12cases) and group 2(0 case) in greater trochanter lateralization, but shaft medialization between group 1(17cases) and group 2(10cases) showed no difference. Loss of neck-shaft angles between group 1(9cases) and group 2(3cases) were not significantly different. Due to loss of reduction, one case in group 1 was reoperated.
CONCLUSION
Application of TSP is not a difficult procedure and reduce excessive sliding of lag screw. And early fuctional recovery without adverse effect of bone healing is possible. So in unstable intertrochanteric fracture, additional use of TSP is effective.

Comparison of Bipolar Hemiarthroplasty and Compression Hip screw on Treatment of Elderly Unstable Intertrochanteric Fractrues: Ik Su Choi, Su In Roh, Dae Yeon Kim, Keun Il Lee, Seung Chan Ko; J Korean Soc Fract 2000;13(1):56-63. Published online January 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.1.56

Abstract PDF: PURPOSE
To evaluate and compare the clinical outcomes of bipolar hemiarthroplasty and compression hip screw on elderly with unstable intertrochanteric fractures We evaluated the clinical results of 65-year or older elderly patients with unstable intertrochanteric fractures between Jan. 1993 to Dec. 1997. 23 patients underwent compression hip screw treatment and 19 patients were treated with bipolar hemiarthroplasty. Functional evaluation was conducted at 3, 6 and 12 month after the operation by hip rating scale of Merle d'Aubigne. Complications, time to weight bearing and hospitalization period were also investigated.
RESULTS
For the bipolar hemiarthroplasty group, functional scale of good or above were seen in 74%, 72% and 67% of the group at 3 months, 6 months and 12 months. However in the compression hip screw group, the good or above results were shown in 57%, 52% and 43% of the group, thus showing a functional deterioration as time progresses. Comparing the overall clinical outcome, the bipolar hemiarthroplasty group showed better results, complication occurred in 26 cases of compression hip screw group and 8 cases of bipolar hemiarthroplasty group, showing better outcomes in the bipolar hemiarthroplasty group.
CONCLUSION
Comparing the length of hospital stay, time to weight bearing, complication and functional superiority of the treatment for elderly unstable intertrochanteric fractures, the bipolar hemiarthroplasty showed superior clinical outcomes than the compression hip screw. Moreover, patients with more unstable fractures and more severe osteoporosis showed better clinical results with bipolar hemiarthroplasty.

Treatment of Unstable Intertrochanteric Fractures of the Femur - Comparative analysis of the postero-medial fixation with or without additional screw -: Jin Hong Ko, Bum Gu Lee, Do Hyun Moon, Young Sung Kim; J Korean Soc Fract 1998;11(3):487-494. Published online July 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.3.487

Abstract PDF: An unstable intertrochanteric fracture lacks continuity of the bone cortex on the opposing surfaces of the proximal and distal fragments. This cortical deficit is due to either comminuti- On on the medial aspect of the neck(calcar-region) or a large and separate posterior trochan-teric fragment. Treatment of unstable intertochanteric fracture have taken method to restore bony contact medially and posteriorly by anatomical reduction or displacement osteotomy. The authors analyzed the 60 unstable intertrochanteric fractures treated by anatomic reduction and internal fixation with a compression hip screw from January 1990 to December 1995. We made a comparative analysis of the postero-medial fixation with additional screw(Group I) and no fixation group(Group II). We tried to find the difference of operation time, blood loss, union time, weight bearing time, neck-shaft angle, sliding length of lag screw and complication rate in two groups. The results were obtained as follows: 1. The mean union time was 11.5 weeks in the Group I and 12.7 weeks in the Group II (p>0.05). 2. The mean weight bearing time was 6.1 weeks in the Group I and 8.3 weeks in the Group II (p<0.05). 3. The decrease of neck-shaft angle was 2.3 degree in the Group I and 5.2 degree in the Group II(p<0.05). 4. The sliding length of lag screw was 5.8mm in the group I and 11.2mm in the group II(p< 0.05). 5. The lower complication rate was obtained in the group I than in the Group II, but two groups showed no significance by statistical analysis. In conclusion, the postero-medial fixation with additional screw in the treatment of unstable intertrochanteric fracture of the femur are suggested that medial cortical stability can be gained and early weight-bearing can be allowed.
