【Abstract】 ObjectiveTo explore the shortterm effects of total hip arthroplasty combined with acetabular finite deepening, soft tissue release and bone wound therapy in the treatment of adult femoral neck fractures and severe ischemic necrosis of the femoral head accompanying hip osteoarthritis. MethodsFrom January 2007 to January 2014, 41 hips in 38 patients of adult femoral neck fractures, avascular necrosis of the femoral head combined with hip osteoarthritis underwent acetabular finite deepening, total hip arthroplasty using non cement prosthesis, soft tissue release, along with the use of bone wound therapeutic instrument, including 28 males, 10 females; aged 24 to 102 years old, with an average age of 65 years; 3 cases of bilateral lesions, 35 cases of unilateral lesion. The Harris scores were measured for statistical analysis and evaluation of curative effect before and after surgery. The data were analyzed by pairedsample t test with SPSS10.0 software, with a statistical significance when P＜0.05. ResultsThe followup period ranged from 6 months to 5 years, averaging 2 years and 6 months. Hip pain disappeared in all cases, which regained the abilityof long walk, self care and daily work.The X ray showed well positioned artificial hip joint, without obvious signs of prosthesis loosening and sinking. The Harris scores increased from 15.16±1.12 preoperatively to 92.42±1.08 postoperatively, with a statistically significant difference of P＜0.01. ConclusionAcetabular finite deepening followed by total hip replacement, combined with soft tissue release and bone wound therapy in the treatment of adult femoral neck fracture, avascular necrosis of the femoral head and ?hip osteoarthritis can obviously improve the stability of the acetabular component, prevent acetabular prosthesis instability caused by poor compatibility of acetabulum, achieving good shorterm therapeutic effect, worthy of clinical popularization and application.
