PURPOSE To compare the result of failed internal fixation of intertrochanteric fractures treated with arthroplasty and 95degrees angled blade plate. MATERIALS AND METHODS From June 2000 to may 2003, there were 12 cases with failed internal fixation of intertrochanteric fractures among 185 cases treated with dynamic hip screw and followed up for more than 1 year. The 4 cases were treated with bipolar hemiarthroplasty, 1 case with total hip arthroplasty, and other 7 cases were treated with 95degrees angled blade plate with allograft, evaluated clinically the operation times, blood loss, walking ability and complication. RESULTS In the 7 cases, which treated with 95degrees angled blade plate, the average operation time was 109 minutes, the average blood loss was 431 ml. The result of keeping abreast of 1 year, no aid ambulation was 4 cases, the cane ambulation was 2 cases, the walker ambulation was 1 case, and there was no pain in 3 cases, mild pain in 4 cases, and no moderate pain. In the 5 cases, which treated with arthroplasty, the average operation time was 157 minutes, the average blood loss was 618 ml. During 1 year, no aid ambulation was 3 cases, the cane ambulation was 1 case, the walker ambulation was 1 case, and no pain in 2 cases, mild pain in 1 case, moderate pain in 1 case. CONCLUSION Both 95degrees angled blade plate and arthroplasty can be useful for failed internal fixation of intertrochanteric fractures, and the choice of implant must be determined with caution, considering the surgical conditions of patient, as well as benefits of each devices
Surgical stabilization is the treatment of choice for both stable and unstable intertrochanteric fractures. Unfortunately, the elderly patient has poor quality of bone. Because of osteoporotic bone, management of unstable comminuted fracture is very difficult in reduction and fixation of fracture. Now the sliding compression hip screw is the device used for hip screws have been used widely. these device have most commonly, and also intramedullary hip screws have been used widely. These device have many advantages in the treatment of interrochanteric fracture. But fixation failure occur not uncommonly in osteoporotic comminuted unstable fracture. For the pupose of stable fixation in osteoporotic femur neck and head, we used the 95degree angled blade plate(=condylar plate). We experienced that the blade portion of condylar plate offer a good fixation stability. clinical results were good in 31 cases of intertrochanteric fracture treated with condylar plate. There was no cutting out of head, excessive shortening and excessive varus deformity. Most of all cases, except one, were united within average 4months. We consider that using the condylar plate for osteoporotic unstable intertrochanteric fracture would be another good modality if surgeons have a surgical skill.
