Clinical effect of total hip replacement in 104 patients suffered from different diseases

Abstract

Objective To evaluate the clinical effect and complications of total hip replacement (THR) in novel femoral neck fracture,old femoral neck fracture, aseptic necrosis of femoral head and coxa degenerative osteoarthropathy. To provide instructions to surgical indications and treatment effects analysis.Methods One hundrde and four patients were divided into 4 groups by disease type: novel femoral neck fracture group (n = 32 ), old femoral neck fracture group (n = 22) ,aseptic necrosis of femoral head group (n =34) and coxa degenerative osteoarthropathy group (n = 16). These patients were followed-up for 12 - 144 months after THR, their Harris standard score and complications data, before and after operation, were analyzed retrospectively. Results After operation, the Harris standard scores were 92. 6 ± 5.8,90. 1 ± 5. 2,86. 3 ± 4. 6,81.9 ±4. 1 in novel femoral neck fracture,old femoral neck fracture,aseptic necrosis of femoral head and coxa degenerative osteoarthropathy groups respectively, which were significantly higher than the scores before operation (25.6±1.8,36.7±2.6,52.9±4.3,42. 1 ±3.8,Ps ＜0.05). Conclusion THR has good effects in the four types of diseases. Short length of stay and high healing rate are marked characteristics of THR. More attention shoud be paid to the complications of THR.
