Results of Single Small Incision Minimally Invasive Plate Osteosynthesis in the Treatment of the Distal Radius Fractures: Young Sung Kim, Jong Pil Kim, Phil Hyun Chung, Ho Min Lee, Bo Sung Go; J Korean Fract Soc 2020;33(2):72-80. Published online April 30, 2020; DOI: https://doi.org/10.12671/jkfs.2020.33.2.72

Abstract PDF: Purpose
This study compared minimally invasive plate osteosynthesis (MIPO) using a single small skin incision and conventional open volar locking plate fixation (OP) for distal radius fracture to identify outcome difference.
Materials and Methods
Forty-three patients who underwent MIPO using a single small skin incision or OP for distal radius fractures were evaluated retrospectively. Of the patients, 21 were treated with MIPO using a single small skin incision and 22 with the OP method through the conventional volar approach. The postoperative radiographic results and clinical outcomes at the final follow-up in each group were compared.
Results
All patients achieved bone union in the MIPO and OP groups. No significant differences in the bone union time, alignment, range of motion, QuickDASH, or pain score were observed. On the other hand, the size of the incision was significant: 23 mm in the MIPO group and 55 mm in the OP group (p<0.001).
Conclusion
MIPO technique using a single small incision showed similar satisfactory radiographic and functional outcomes compared to conventional OP for distal radius fractures. The MIPO technique using a single small incision offered advantages, including cosmetic benefits and minimal soft tissue damage, is recommended, particularly in young women and high functional demand patients.

Comparative Analysis of Minimally Invasive Plate Osteosynthesis and Intramedullary Nailing in the Treatment of the Distal Tibia Fractures: Ho Min Lee, Young Sung Kim, Jong Pil Kim, Phil Hyun Chung, Suk Kang, Kaung Suk Jo; J Korean Fract Soc 2018;31(3):94-101. Published online July 31, 2018; DOI: https://doi.org/10.12671/jkfs.2018.31.3.94

PURPOSE
This study compared the radiological and clinical results of minimally invasive plate osteosynthesis (MIPO) and intramedullary nailing (IMN) of distal tibial fractures, which were classified as the simple intra-articular group and extra-articular group.
MATERIALS AND METHODS
Fifty patients with distal tibial fractures, who could be followed-up more than 12 months, were evaluated. Group A consisted of 19 patients treated with MIPO and group B consisted of 31 patients treated with IMN. The results of each group were analyzed by radiological and clinical assessments.
RESULTS
The mean operation times in groups A and B were 72.4 minutes and 65.7 minutes, respectively. The mean bone union times in groups A and B were 16.4 weeks and 15.7 weeks, respectively. The bone union rate in groups A and B were 100% and 93%, respectively. The ranges of ankle motion were similar in the two groups at the last follow-up. The mean American Orthopaedic Foot and Ankle Society score was similar: 90.1 in group A and 90.5 in group B. The radiological and clinical results were similar in the intra and extra-articular groups. In groups A and B, two cases of posterior angulation and five cases of valgus deformity of more than 5Â° were encountered.
CONCLUSION
Both MIPO and IMN achieved satisfactory results in extra-articular AO type A and simple articular extension type C1 and C2 distal tibia fractures.

A Comparison between Compression Hip Screw and Intramedullary Nail for the Treatment of AO/OTA A2.2 Intertrochanteric Femoral Fracture: Phil Hyun Chung, Suk Kang, Jong Pil Kim, Young Sung Kim, Ho Min Lee, Jong Hyun Kim; J Korean Fract Soc 2013;26(1):44-49. Published online January 31, 2013; DOI: https://doi.org/10.12671/jkfs.2013.26.1.44

Abstract PDF

PURPOSE
To compare the result between the compression hip screw (CHS) and intramedullary (IM) nail for the treatment of AO/OTA A2.2 intertrochanteric fracture.
MATERIALS AND METHODS
We retrospectively reviewed 95 cases of AO/OTA A2.2 intertrochanteric fracture, which were treated with CHS or IM nail by one surgeon from March 1994 to December 2009. One group was treated with CHS (Group I, 28 cases) and the other was treated with IM nail (Group II, 67 cases). We evaluated the mean operation time, the amount of bleeding and transfusion, hospital duration, radiological results and the clinical outcome with the mobility score of Parker and Palmer.
RESULTS
Radiologically, the tip-apex distance, change of neck-shaft angle, and union time were not significantly different between both groups (p>0.05). Clinically, the mean operation time, the amount of bleeding and transfusion, hospital duration and the mobility score were not significantly different (p>0.05). The post-operative complications were lag screw slippage over 25 mm (1 case) and loosening of device (1 case) in group I. In group II, there were perforation of the femoral head (1 case), nail breakage (1 case) and deep infection (1 case).
CONCLUSION
There was no significant differences that are clinical and radiological results in the treatment of AO/OTA A2.2 intertrochanteric fracture, using CHS and IM nail.

Missed Variation of the Essex-Lopresti Injury Associated with Type-I Monteggia Equivalent Lesion: A Case Report: Young Sung Kim, Phil Hyun Chung, Suk Kang, Ho Min Lee, Jong Pil Kim; J Korean Fract Soc 2012;25(3):219-222. Published online July 31, 2012; DOI: https://doi.org/10.12671/jkfs.2012.25.3.219

Abstract PDF: The authors report the case of a patient with the combination of a Type I Monteggia equivalent lesion and Essex-Lopresti injury. This combination of injury is very rare, and an associated distal radioulnar injury is often missed. We hope our experience illustrates the need to examine the wrist joint carefully and to be aware of the potential for distal radioulnar joint instability in all patients with type I Monteggia equivalent lesions.

Interposition of Periosteum in Distal Tibial Physeal Fractures of Children: Phil Hyun Chung, Suk Kang, Jong Pil Kim, Young Sung Kim, Jae Woo Cho; J Korean Fract Soc 2011;24(1):73-78. Published online January 31, 2011; DOI: https://doi.org/10.12671/jkfs.2011.24.1.73

Abstract PDF: PURPOSE
To evaluate the factors influencing periosteal interposition in distal tibial physeal fractures of children.
MATERIALS AND METHODS
34 cases of distal tibial physeal fractures were analysed. We confirmed the presence of periosteal interposition with MRI in all cases and accessed the relationship between periosteal interposition and gender, age, cause of injury, type of fracture, degree of initial displacement and after closed reduction.
RESULTS
9 (26.5%) of 34 fractures had interposed periosteum. There was no statistically significant correlation between periosteal interposition and gender, age, cause of injury (p>0.05). 5 (83.3%) of 6 pronation-eversion-external rotation type of fractures according to Dias-Tachjian classification had interposed periosteum and that was a statistically significant correlation (p=0.006). As Salter-Harris type was toward to high degree, there were decreasing tendency of periosteal interposition (p=0.026). There was high rate of periosteal interposition in case of displacement more than 2 mm in each initial and after closed reduction (p<0.05).
CONCLUSION
There was high incidence of periosteal interposition in pronation-eversion-external rotation type with displacement more than 2 mm in distal tibial physeal fractures of children. But, periosteal interposition could occur in fractures with mild displacement less than 2 mm, if initial fracture displacement was more than 2 mm, the methods of treatment should be decided after confirm the presence of periosteal interposition with MRI after closed reduction.

Double Tension Band Wiring for Olecranon Fractures: Suk Kang, Chung Soo Hwang, Phil Hyun Chung, Young Sung Kim, Jin Wook Chung, Jong Pil Kim; J Korean Fract Soc 2008;21(2):130-134. Published online April 30, 2008; DOI: https://doi.org/10.12671/jkfs.2008.21.2.130

Abstract PDF

PURPOSE
To evaluate the clinical results of double tension band wiring for communited olecranon fractures involving proximal 1/3.
MATERIALS AND METHODS
We reviewed 9 cases of communited olecranon fractures involving proximal 1/3 treated with double tension band wiring followed for minimum 10 months. There were 2 cases of olecranon fractures involving only proximal 1/3, 6 cases of olecranon fractures involving from proximal 1/3 to middle 1/3 and 1 case of olecranon fractures involving from proximal 1/3 to distal 1/3. We analyzed the bone union time, radiologic results for gap, reduction loss, pin migration, pain, range of motion, complications and functional outcomes at last follow up.
RESULTS
All patients had solid bone union without additional surgery and average union time was 10.3 weeks. Anatomical reduction could be obtained in 8 of 9 cases but there was 1 mm step off in one case. 36 pins were used to fix the fractures, 1 pin of 18 distal pins and 2 pins of 18 proximal pins were migrated to backward but there was no reduction loss. Only 1 distal pin needed early removal due to skin irritation. Average range of motion ranged from flexion contracture 3.3 degrees to further flexion 137.8 degrees. On functional analysis, we got 8 cases of good result, 1 case of fair result and there was no poor result.
CONCLUSION
Double tension band wiring for comminuted olecranon fracture involving proximal 1/3 was concluded to give a firm fixation of the fracture site as bone union could be acquired without serious pin problems.

Treatment of Subtrochanteric Femur Fractures Using Intramedullary Devices: Chung Soo Hwang, Phil Hyun Chung, Suk Kang, Jong Pil Kim, Young Sung Kim, Chong Suk Park, Sang Ho Lee; J Korean Fract Soc 2008;21(1):13-18. Published online January 31, 2008; DOI: https://doi.org/10.12671/jkfs.2008.21.1.13

Abstract PDF

PURPOSE
The purpose of this study is to compare the result between closed reduction and minimal open reduction in case of difficult reduction for subtrochanteric fractures fixed with intramedullary nail.
MATERIALS AND METHODS
From Jan. 2001 to May 2005, 35 cases of subtrochanteric femur fracture treated by intramedullary nail and followed up for more than a year were selected out of 42 subtrochanteric femur fractures. Fielding classification and Russel-Taylor classification were used, and according to the fracture classification and method of reduction, the patients were grouped into closed or open reduction group. Fracture with minimal displacement or anatomical reduction was fixed by closed reduction, but in case of failed closed reduction or loss of reduction, minimal incision was made for open reduction and internal fixation, and the result between two groups were compared.
RESULTS
In total of 35 cases, 15 cases were fixed by closed reduction and the rest 20 cases required open reduction. Operation time, amount of transfusion, total hospital days, partial weight bearing ambulation, and union time did not show significant differences between two groups. Ambulation and range of motion after the operation were satisfying in both groups.
CONCLUSION
In treatment of subtrochanteric femur fracture with intramedullary nail, both closed and open reduction shows satisfying result, therefore when anatomical reduction is difficult to achiev by closed reduction, minimal incision open reduction and additional fixation is strongly recommended to obtain anatomical reduction and firm fixation.

Published online October 31, 2007; DOI: https://doi.org/10.12671/jkfs.2007.20.4.339

Abstract PDF: The complications following paediatric femur fracture are leg length discrepancy, angulation deformity, rotational deformity, ischemic limb. But, stiff knee is rarely expressed after trauma like paediatric femur fracture. We report a case of stiff knee due to entrapment of quadriceps femoris tendon at displaced fracture site after conservative treatment by Russel traction and hip spica cast in paediatric femur fracture. We treated successfully by resection of distal end of proximal segment of femur and release of quadriceps femoris tendon for flexion contracture of the knee.

Published online July 31, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.3.335

Abstract

PURPOSE
We are reporting the result of comminuted midshaft fractures of clavicle treated by reconstruction plate fixation and PDS augmentation easily fixing butterfly fragments with minimal soft tissue dissection.
MATERIALS AND METHODS
We reviewed 42 cases of operatively treated displaced comminuted midshaft fractures of clavicle at our hospital from March, 2001 to May 2004 whom were followed up for more than one year after the operation. According to Robinson classification, we grouped simple fractures as group A, and comminuted fractures as group B. Internal fixation using reconstruction plate has been chosen for type A fracture. Type B has been treated by reconstruction plate fixation with PDS augmentations. Shoulder function, union time and complications has been studied according to the fracture type retrospectively.
RESULTS
All cases had complete bone union with average union time of 8.6 weeks for type A and 8.9 weeks for type B. Weitzman functional evaluation did not show significant differences.
CONCLUSION
PDS augmentation in comminuted midshaft fracture of clavicle easily fix the butterfly fragments with least soft tissue damage and lessen the bone graft. Therefore it considered to be one of the available treatment methods for comminuted midshaft fracture of clavicle.

Abstract PDF

PURPOSE
To evaluate and compare the outcome in fracture of distal tibial metaphyseal fractures involving ankle joint and not involving the ankle joint treated by interlocking imtramedullary nailing.
MATERIALS AND METHODS
Twenty six cases of distal tibial metaphyseal fractures treated by interlocking intramedullary nailing whom were able to follow up for more one year were selected and 10 cases involved ankle joint and the rest 16 cases did not. In all cases, more than 2 distal locking screws were inserted after reaming for the nailing, and cannulated screws or K-wires fixation were inserted for 8 cases of fractures involving ankle joint out of 10. We analyzed preoperative fracture type, union time, function of joint, and complications at final follow up.
RESULTS
According to Robinson's classification for distal tibial metaphyseal fractures, there were 9 cases of type I, 7 of 2A, 4 of 2B, 6 of 2C. Union time taken for distal tibial fractures involving ankle were average of 17 weeks (12~20 weeks) and for the fractures not involving ankle joint were average of 19 weeks (12~28 weeks). Klemm and Borner's functional evaluation showed above good in 8 cases (80%) of fracture involving ankle joint and 13 cases (81%) of fracture not involving the ankle joint, and functional evaluation did not show significant differences as well as the complication rate in both group.
CONCLUSION
Interlocking intramedullary nailing is one of the effective methods for treatment of distal tibial metaphyseal fracture involving articular surface of the ankle.

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.
