Abstract:
Objective To evaluate the potential high risk factors of femoral head necrosis after femoral neck surgery in adult patients. Methods From January 2009 to October 2014,390 patients with femoral neck fractures in our hospital were treated with multiple hollow compression screws. All patients were followed up for 12 to 60 months. Then retrospectively analyzed the incidence rates of femoral head nec-rosis and the clinical data about age,gender,fracture side,Garden index,fracture shift condition,internal medicine complications,whether to do lower limb preoperative traction,restoration method,postoperative load time and whether take out hollow compression screw internal fixa-tion,so as to explore the higher risk factors for femoral head necrosis. Results Among the 390 cases,352 cases got followed up. There were 45 cases of them ended with nonunionand 49 cases ended with femoral head necrosis. The univariate regression analysis results showed that the age,fracture shift condition,internal medicine complications,postoperative load time and Garden index,whether take out internal fixation were risk factors for femoral head necrosis (P<0. 05). The multi-factor results showed that aged from 40 to 60 years old,transfered fracture, seriously complications,time of loading less than 3 mouths,Ⅲ and Ⅳ Garden index,take out internal fixation were the high risk factors for femoral head necrosis (P<0. 05). Conclusion Patients who aged from 40 to 60 years old and having transfered fracture,seriously complica-tion,early weight bearing,high Garden index and internal fixation take-out would increase the risk of femoral head necrosis.
