The influence of restoring femoral offset on the function of hip after total hip arthroplasty
Objective To analyze the influence of restoring femoral offset on the function of hip after total hip arthroplasty (THA). Methods 68 patients underwent the primary and unilateral total hip arthroplasty were studied from January 2005 to January 2008. The mean follow-up period was 19.2 months, ranged from 9 to 24 months. A anterolateral approach was applied in all the procedures. Preoperative and postoperative femoral offset, the abductor lever arm and the leg length were compared through radiographic measurements, while, the ROM of hip and the Harris scores were recorded respectively. Statistical analysis were performed by SPSS13.0 software. Results Femoral offset correlated positively with the length of the abductor lever arm (r=0.534, P<0.001). Femoral offset was significantly positive related to the ROM of hip (r=0.403, P<0.001). Femoral offset was significantly positive related to the Harris scores (r=0.344, P<0.001). Restoration of femoral offset influenced the leg length (x2=4.23，P<0.05). Conclusions It is very important to restore femoral offset in THA, on the basis of improving the abductor strength, ROM and stability of hip.
