Risk factors for femoral fracture in lateral decubitus direct anterior approach total hip arthroplasty using conventional stems: a retrospective analysis

Abstract Objective To provide guidelines for surgery and reduce the incidence of fracture, this study analyzed relationship between femoral fracture related factors in direct anterior approach (DAA) total hip arthroplasty (THA) lateral decubitus position. Method A retrospective series 273 consecutive patients who underwent THA with DAA position was analyzed. Each performed by same surgeon a conventional operation bed stem. The correlations sex, age, body mass index (BMI), height, osteoporosis, superior iliac spine-greater trochanter distance (ASIS-GTD), joint disease were univariate analysis logistic regression analysis. Results Among all procedures, 35 hips had fractures, including 30 greater 4 proximal splits, 1 perforation. 12.82%. Univariate showed no significant difference BMI, or age. However, osteoporosis caused an increase while decreased as height ASIS-GTD increased. neck lower cases osteonecrosis head than other diseases. Logistic correlation ASIS-GTD, fractures. Patients high possibility (OR = 2.414); increasing 0.938). Conclusion Lateral can be successfully using stem, effectively saving medical resources. Osteoporosis shorter independent risk fracture.
