Treatment for Concurrent Ipsilateral Femoral Neck and Shaft Fractures Using Reconstruction Nail with Temporary K-Wires

PURPOSE: The purpose of this study is to evaluate the results of operative treatment using a reconstruction nail after temporary K-wire fixation of the femoral neck for ipsilateral femoral neck and shaft fractures. MATERIALS AND METHODS: A total of 11 cases were treated, which were followed-up for more than two years, between August 2007 and July 2012. The average age was 51 years (29-69 years) and men were dominant counting eight cases. All cases were operated with a reconstruction nail after temporary K-wire fixation of the femoral neck. Bone union periods, alignment, etc. were evaluated by radiological methods and accompanying damage and complications were also investigated. Functional evaluation was performed in accordance with Friedman and Wyman criteria at the last follow-up. RESULTS: The average time for union of the femoral shaft was 22.5 weeks (12-32 weeks), and femoral neck was 13.1 weeks (8-20 weeks). There was no nonunion, and four femoral shaft fractures resulted in delayed union. There was one case of leg length discrepancy more than 2 cm long, but malalignment of more than 10 degrees was not observed. Avascular necrosis of the femoral head did not occur. Functional results were good in eight cases, fair in two cases, and poor in one case. CONCLUSION: Treatment with reconstruction nailing after temporary K-wire fixation of the femoral neck is thought to be a good method which prevents neck displacement and has low complication rates.

The Effect of Temporary K-wire Fixation in the Plate Fixation for Displaced Intra-articular Calcaneal Fracture / 대한족부족관절학회지

PURPOSE: This study was designed to evaluate the clinical efficacy of temporary K-wire fixation in F-plate fixation for displaced intraarticular calcaneal fractures. MATERIALS AND METHODS: Two groups (group 1 with F-plate fixation only and group 2 with temporary K-wire fixation and F-plate fixation) of patients were included in this study. The temporary K-wire was removed six weeks after the operation. Each group consisted of 33 cases. Rotational axis angles were measured radiographically and the foot and ankle outcome score (FAOS) was used for clinical assessment. RESULTS: In group 1, the mean rotational axis angle was reduced from 27degrees preoperatively to 5.59degrees postoperatively and the angle at last follow-up was 9.94degrees. There was an increase in angle of 4.35degrees between postoperative and the last follow-up measurement. In group 2, the mean rotational axis angle was reduced from 21.2degrees preoperatively to 4.39degrees postoperatively and the angle at last follow-up was 5.91degrees. There was an increase in angle of 1.52degrees between postoperative and the last follow-up measurement. Significant difference in the changes of rotational axis angle was observed between the two groups. However, no significant difference in FAOS was observed between the two groups. CONCLUSION: Temporary K-wire fixation can prevent reduction loss when treating displaced intra-articular calcaneal fractures with an F-plate.
