Femoral neck fractures fixed with intramedullary cannulated screws: factors for postoperative functional recovery

doi:10.3969/j.issn.2095-4344.2017.19.008

Abstract

Abstract:

BACKGROUND: Hip arthroplasty and internal fixation with intramedullary cannulated screws are mainly used for senile femoral neck fractures. However, osteoporosis can usually lead to failure in internal fixation.

OBJECTIVE: To analyze the joint function after fixed with intramedullary cannulated screws in elderly patients with femoral neck fractures, and to explore the factors related to functional recovery.

METHODS: Clinical data of 89 patients with femoral neck fractures undergoing internal fixation with intramedullary cannulated screws after 2-year follow-up were analyzed retrospectively. The sex, age, Garden type, bone mineral density, body mass index, screw distribution, reduction index, operation time, bearing time and Harris hip scores were analyzed. Rank related analysis and accumulative Logistic regression analysis were performed on SPSS18.0 software.

RESULTS AND CONCLUSION: (1) Normal Q-Q plot and normality test results indicated that the Horris scores in all patients after 2-year follow-up presented with skewed distribution (P=0.000). (2) Rank related analysis showed that age, Garden type, bone mineral density, and reduction index were related with Harris score (P < 0.05 or P < 0.01). (3) Accumulative Logistic regression analysis showed that the independent variables including age, Garden type, bone mineral density, and reduction index made significant effect on Harris hip scores. (4) To conclude, age, Garden type, bone mineral density, and reduction index are important factors for functional recovery of the hip after fixed with intramedullary cannulated screws.
