摘要:
Background: Although the blood supply of femoral intertrochanter is abundant and the fracture is easier to achieve union, a part of patients are associated with poor function after prognosis. Objective: To explore the risk factors affecting the treatment outcome of femoral intertrochanteric fractures so as to provide a guide for a further improvement of curative effect. Design: Retrospective analysis of risk factors according to the diagnose. Setting and participants: The experiment was finished in the Department of Orthopedics, Xuanwu Hospital, Capital University of Medical Sciences. A total of 121 patients including 67 males and 54 females between the ages of 47 and 91 years with intertrochanteric fractures admitted in hospital were reviewed. Interventions: Measures were analyzed by univariance analysis. Quantitative data were processed with t test and qualitative data with χ2 test. The parameters with P < 0.05 were analyzed with Logistic regression. Main outcome measures: Age, sex, fracture types, therapeutic measure, reduction status, health evaluation of old traumatized patients (HEOTP), multi-injury and hip score. Results: According to Harris' hip score (HHS), 31 cases were excellent, 33 cases were fine, 47 cases were in middle level and 10 cases were bad. Univariance analysis manifested that age (t = 4.072, P = 0.001), therapeutic measure (χ2 = 34.43, P = 0.000), reduction status (χ2 = 16.9, P = 0.000), HEOTP (t = 14.09, P = 0.000) and multi-injury (χ2 = 4.109, P = 0.037 were closely correlated with the prognosis of the femoral intertrochanteric fractures with a significant difference (P < 0.05). Logistic regression also showed that age (r = - 0.125 3, P = 0.008 6), therapeutic measure (r = -1.747 8, P = 0.010 7), reduction status (r = -2.083 9, P = 0.002 9), HEOTP (r = - 0.058 2, P = 0.000 2), multi-injury (r = -4.782 2, P = 0.010 2) were independent risk factors affecting hip score and prognosis of the femoral intertrochanteric fractures (P < 0.05). Conclusion: The function of hip suffering intertrochanteric fracture is obvious affected by age, therapeutic measure, reduction status, HEOTP and multi-injury.
