摘要
Abstract
BACKGROUND:Anatomic medul ary locking (AML) femoral prosthesis is circular cylinder and has satisfactory efficacy. However, some scholars found the complications such as thigh pain, loss of bone at the proximal end of the femur, and wearing-related osteolysis. F2L femoral prosthesis is cone-shaped and also has satisfactory efficacy, but the thigh pain incidence is relatively low. <br> OBJECTIVE:To compare the intermediate-long term results of AML versus F2L in total hip arthroplasty. <br> METHODS:Between November 1997 and January 2005, we retrospectively reviewed 60 patients (66 hips) undergoing total hip arthroplasty using biological femoral prosthesis. At fol ow-up examination, 58 hips in 52 patients were available for clinical and roentgenographic review. 26 AML devices were placed in 24 patients, and 32 F2L devices were placed in 28 patients. The AML group were reviewed with an average of 12.7 years fol ow-up (range 10 years and 3 months to 15 years and 5 months), while the F2L group were reviewed with an average of 9.5 years fol ow-up (range 8 years and 3 months to 11 years and 1 month). The clinical results were evaluated with Harris methods and X-ray examination. Kaplan-Meier analysis was performed to evaluate the survival of femoral component. End point was radiographical loosening or revision of the femoral component for any reason. <br> RESULTS AND CONCLUSION:There were no significant difference between AML and F2L about Harris score in the latest fol ow-up (P>0.05). After surgery, the incidence of thigh pain was significantly lower in F2L group than that in AML group (P<0.05). In AMKL group, the stress-shielding 1 level was observed in 21 hips (81%), and 2 level in five hips (19%);in F2L group, the stress shielding 0 level was observed in 20 hips (62%) and 1 level in 12 hips (38%). There were significant differences between the two groups (P<0.05). The stress shielding showed significant differences between the two groups (P<0.05). The incidence of osteolysis in F2L group was significantly lower than that in AML group (P<0.05). Kaplan-Meier analysis showed that, the survival rate of both AML and F2L components were 1.0 (95%confidence interval:0.98-1.00). Experimental findings indicate that, both AML and F2L femoral prosthesis have a satisfactory long-term efficacy after total hip arthroplasty, and the incidence of thigh pain and osteolysis is significantly lower in F2L group.关键词
