Retrospective Comparative Study of the Intraoperative Fracture Gap Compression in the Treatment of Intertrochanteric Fracture Using Proximal Femoral Nail Antirotation: Se Jin Kim, Hong Man Cho, Jiyeon Park, Ki Yong An, Young Woo Chung, Woojin Shin; J Korean Fract Soc 2020;33(4):179-188. Published online October 31, 2020; DOI: https://doi.org/10.12671/jkfs.2020.33.4.179

Purpose
Intertrochanteric fractures can be treated using proximal femoral nail antirotation (PFNA). This study examined the clinical and radiological results of the intraoperative fracture compression.
Materials and Methods
Ninety-four patients underwent intraoperative compression (Group I), and 88 patients underwent natural sliding only (Group II). The patients were followed-up for more than two years. All patients met the following seven conditions: (1) AO/OTA 31-A1, A2 type intertrochanter fracture, (2) availability of compression of more than one cortical bone in the anterior or medial region of the fracture site under the preoperative imaging test, (3) Singh index grade ≥3, (4) blade position: center-center, center-inferior, (5) tip-apex distance <25 mm, (6) reduction status of good or very good, and (7) positive or neutral medial cortical support position with slightly valgus reduction.
Results
A slight tendency toward significant differences in acute phase pain between the two groups was observed at six weeks postoperatively (p=0.073). Twenty-four months after surgery, lateral extension of the PFNA helical blade between the two groups showed significant differences (p=0.017). Fracture gaps measured immediately after surgery showed significant differences (p=0.001), and a clear tendency for a significant difference in the average fracture union time was found (p=0.065).
Conclusion
Intraoperative fracture compression, intraoperative fracture compression appears beneficial to achieve a successful union of trochanteric fractures provided that all conditions are met to apply the method safely.

Rendezvous Surgery for Peri-Implant Fractures around Locking Compression Plate on Anterolateral Bowed Femur - A Case Report -: Hong Man Cho, Jiyeon Park; J Korean Fract Soc 2020;33(3):159-163. Published online July 31, 2020; DOI: https://doi.org/10.12671/jkfs.2020.33.3.159

Abstract PDF: An 84-year-old female visited with an intertrochanteric femoral fracture. The patient had undergone an open reduction and internal fixation with a compressive plate and elastic nail in an ipsilateral atypical diaphyseal femoral fracture in the past. Compressive plate and elastic nail remained, and anterolateral bowing was presented. To treat the periprosthetic trochanteric fracture, a proximal femoral nail was used without removing the previously inserted compressive plate. Under the “rendezvous” technique, using a combination of fixating intramedullary nail and compressive plate simultaneously, the distal screw was fixed, and a femoral head lag screw was inserted after reducing the fracture. Complete union of the fracture was achieved 16 months after the operation, and a decrease in mobility function was not found postoperatively. The authors report this case for the “rendezvous” technique as a treatment option for elderly patients with periprosthetic trochanteric fractures, who had previously undergone surgical treatment for ipsilateral atypical diaphyseal femoral fractures with anterolateral bowing.

Intrapelvic Penetration of Lag Screw in Proximal Femoral Nailing: A Case Report: Jung Woo Lee, Hong Man Cho, Jae Woong Seo; J Korean Fract Soc 2017;30(4):203-208. Published online October 31, 2017; DOI: https://doi.org/10.12671/jkfs.2017.30.4.203

Abstract PDF

Hip fractures are common among elderly individuals. Internal fixation with the intramedullary system has been widely used to treat intertrochanteric femur fractures. The Gamma 3 nail is a useful device for fixating trochanteric fractures of the proximal femur. We report a rare complication of medial pelvic penetration of the lag screw of a Gamma 3 nail two months after surgery. There was a complete separation between the nail body and lag screw, and the lag screw penetrated through the acetabulum into the pelvis. We report a case of unstable intertrochanteric fracture with intrapelvic penetration after surgical treatment with proximal femoral nailing and a case followed by fatal results.

Removal Methods for Broken Proximal Femoral Nails Using Ball Tip Guide Wire: Technical Note and Two Cases Report: Bong Ju Park, Hong Man Cho; J Korean Fract Soc 2014;27(4):315-320. Published online October 31, 2014; DOI: https://doi.org/10.12671/jkfs.2014.27.4.315

Abstract PDF

Recently, the use of intramedullary nailing for proximal femoral fractures has increased. Breakage of the nail usually occurs at the un-united fracture site, and it is a rare complication of intramedullary nailing of the femur. However, removal of the distal fragment of a broken nail is a challenging problem. Herein, the authors describe the methods used for removal of relatively fixed or strongly fixed broken intramedullary nails in two different cases.

Treatment of Unstable Intertrochanteric Fracture in Elderly Patients : Comparison between the Results of Internal Fixation Using Compression Hip Screw and Cemented Bipolar Hemiarthroplasty: Myung Sik Park, Woo Chul Jung, Hyuk Park, Byung Yun Hwang, Young Jin Lim, Myung Guk Jung, Hong Man Cho; J Korean Fract Soc 2009;22(3):138-144. Published online July 31, 2009; DOI: https://doi.org/10.12671/jkfs.2009.22.3.138

Abstract PDF

PURPOSE
To perform comparative analysis between the results of internal fixation using compression hip screw and cemented bipolar hemiarthroplasty in unstable intertrochanteric fracture in elderly patients.
MATERIALS AND METHODS
From January 2001 to October 2006, we reviewd 73 patients, who were treated surgically for unstable intertrochanteric fractures, with a minimum of 2 years follow up. The patient's age was older than 60 year old. The patients were divided into two groups and evaluated, retrospectively. One group was treated with cemented bipolar hemiarthroplasty (Group A, 34 cases), and the other group was treated with compression hip screw (Group B, 39 cases). We evaluated the amount of intraoperative bleeding, operative time, clinical results and complications between the two groups.
RESULTS
The amount of intraoperative bleeding and operative time were no statistically significant between the two groups. Group A showed a better result than Group B for clinical outcome using Johnson Daily Activity of Life. Complications in the group A were comprised of dislocation (1 case), nonunion of greater trochanter (1 case), infection (1 case) and loosening (1 case), and those in the group B were comprised of loss of fixation (8 cases) and infection (1 case).
CONCLUSION
We found that short-term outcomes of cemented bipolar hemiarthroplasty for unstable intertrochanteric fractures were satisfactory. However, a longer-follow up period is necessary to clarify the efficacy of cemented bipolar hemiarthroplasty.

Treatment of the Proximal Femoral Fractures with Proximal Femoral Nail Antirotation (PFNA): Myung Sik Park, Young Jin Lim, Young Sin Kim, Kyu Hyung Kim, Hong Man Cho; J Korean Fract Soc 2009;22(2):91-97. Published online April 30, 2009; DOI: https://doi.org/10.12671/jkfs.2009.22.2.91

Abstract PDF

PURPOSE
To analyze the clinical and radiologic results of treatments in proximal femoral fracture with Proximal Femoral Nail-Antirotation (PFNA).
MATERIALS AND METHODS
We retrospectively reviewed the results of 21 cases of proximal femoral fracture treated with PFNA from September 2006 to October 2007 which could be followed up for minimum of more than a year. The mean age was 61.5 (20~88) years old. Male were involved in 12 cases, female in 9 cases. The mean follow up was 14.3 (12~18) months. The Garden alignment index, Cleveland index, tip apex distance were evaluated by post-operative radiologic evaluation and complications of bone union, failure of internal fixation and deformity were evaluated by follow up radiologic findings. Clinical results were assessed by social function score of Jensen and mobility score of Parker and Palmer at last follow up.
RESULTS
All fractures were united and the mean time to bone union was 15.7 (13~18) weeks. Garden alignment index showed good results of above 'good' in 15 cases (71.4%), Cleveland index showed 14 cases (66.4%) positioning in zone 5 and tip apex distance showed 17.81 (+/-5.65~27.52) mm in radiologic findings. The mean sliding of blade was 1.32 (0.34~2.94) mm in follow up radiologic findings and fracture of distal locking screw area was found in 1 case as a complication. Among 21 cases, the function before injury was completely recovered in 15 cases (71.4%) which were assessed by social function score of Jensen and 13 cases (61.9%) by mobility score of Parker and Palmer.
CONCLUSION
We think that PFNA is effective osteosynthetic device for proximal femur fracture with satisfactory radiologic and clinical outcomes.
