PURPOSE This study was conducted in order to demonstrate the radiologic and clinical results of using the Asian type gamma 3 nail in treatment of trochanteric fractures. MATERIALS AND METHODS Patients underwent operations with gamma 3 nails between August 2010 and August 2012. For the radiologic evaluation, we analyzed bone quality, fracture pattern, reduction quality, union period, and position of lag screw (tip-apex distance, Cleveland index). For the clinical evaluation, we analyzed mobility score of Palmer and Parker and Jensen's functional score. RESULTS The mean union was taken at 17.4 weeks (14-25 weeks). Two cases (4.3%) underwent reoperation due to cutting out of the hip screws. The clinical outcomes of Parker and Palmer's average mobility score changed from 7.3 to 5.8 (79%), Jensen's functional score was 1.3 to 1.8 (72%). CONCLUSION We achieved excellent clinical and radiological outcomes; therefore, Asian type gamma 3 nail is effective in treatment of trochanteric fractures of the femur in Korea.
PURPOSE To evaluate the cause and treatment results of nonunion of humerus shaft fractures. MATERIALS AND METHODS 39 cases were treated for humerus shaft nonunion between February 1990 and May 2002. The presence of open wounds, initial treatment modality after injury, treatment method for the nonunion and time to union were studied using medical records. The fracture type and appropriateness and problems of the initial surgical treatment were reviewed. Also, Pain and functional recovery in daily living were evaluated in the outpatient clinic, after surgery for nonunion. RESULTS Amongst the 30 cases, transverse fracture was the most common with 19cases. Most of 29 cases, initially surgically treated, revealed incorrect selection of the internal fixator or technical errors. For surgical treatment of nonunion, open reduction and internal fixation with cancellous bone graft was performed, most commonly, in 36 cases (92.3%). All cases showed clinical and radiographic union at an average of 13.3 weeks. More than 90% of the patients replied minimal pain and excellent functional recovery of daily living at final follow-up. CONCLUSION If treated with surgery by correct selection of internal fixation methods and accurate technical skills, nonunion incidence can be reduced.
