Early results of the proximal femoral nail antirotation-Asia for intertrochanteric fractures in elderly Chinese patients.

OBJECTIVE To report early efficacy and safety of the proximal femoral nail antirotation-Asia for intertrochanteric fractures in elderly Chinese patients. METHODS This retrospective study was carried out in the Second Hospital of Anhui Medical University, Anhui, China between June 2009 and December 2012. A total of 108 patients with intertrochanteric fractures were available for the outcome analysis in the study. There were 62 female and 46 male patients with a mean age of 75 +/= 10 years. The stable group included 18 cases of 31 A1 fractures, the unstable group included 68 cases of 31 A2 fractures, and 22 cases of 31 A3 fractures. Follow-up evaluations were performed at 1, 3, 6, 9, and 12 months, and every year thereafter. RESULTS During the average 29 +/= 9 months early follow-up period, 4 patients (4%) were lost, and 6 patients (6%) died within 6 months due to causes unrelated to the fracture. Fracture union occurred in all patients, 83 patients (85%) showed an excellent, or good outcome. The mean Harris Hip Score was 85.2 +/= 7.5 points. Mechanical failures, such as bending, or breaking of the implant were not seen, and cut-outs were not observed. CONCLUSION The results suggest that proximal femoral nail antirotation-Asia is effective and safe in the treatment of inter-trochanteric fractures in elderly Chinese patients.
