Objective To evaluate the therapeutic effects of the integration of impaction bone grafting reconstructing femur trochanter and femoral head arthropalsty in the treatment of unstable intertrochanteric fractures in aged patients. Methods From January 2006 to December 2008,21 cases unstable intertrohanteric fractures with serious osteoporosis were treated with impaction bone grafting reconstructing the femur trochanter and femoral head arthropalsty. Results Functional assessment based on the Harris score ,great in 14 cases, good in 5 cases, medium in 2 cases. The excellent and good rate was 90. 4%. Conclusion The integration of impaction bone grafting reconstructing femur trochanter and femoral head arthropalsty is convenient to treat unstable intertrochanteric fractures in aged patients.

[Objective]To compare curative effects of radial head resection with internal fixation in treatment of Mason type-Ⅱ、Ⅲ fracture of radial head.[Method]Forty-five patients with Mason type-Ⅱ、Ⅲ fracture of radial head were dividered into 2 groups(A and B).The patients in group A(n=23) were performed with radial head resection.The patients in group B(n=22) were performed with open reduction and internal fixation.The results of the two groups were assessed for statistical analysis on the following aspects: pain,motion,strength and X-ray finding.Broberg and Morrey criterion were used to compared curative effect of elbow function between the two groups.[Result]The patients in the two groups were followed up for a mean time of 8 years(group A) or 3 years(group B).The difference of the pain VAS score,mean flexion/extension of the elbow,Broberg and Morrey elbow scores,carrying angle and shift of radius between the two groups were with statistical significance(P0.05).[Conclusion]In comparing with the radial head resection,open reduction and internal fixation can obtain more satisfactory elbow motion,greater muscle strength and better joint function m the treatment of Mason type-Ⅱ、Ⅲ fracture of radial head.
