Revision Total Hip Arthroplasty Using Allogenic Chip Bone Grafts and Cement in Acetabular Bone Deficiencies: Minimum Two Year Clinical and Radiological Analysis / 대한정형외과학회잡지

The purpose of this study was to analyze the minimum two year clinical and radiological results of revision total hip arthroplasties using allogenic chip bone graft and cement in acetabular bone deficiencies. Thirty six revision total hip arthroplasties that had been performed in thirty four patients between Sep. 1992 and May. 1994 at Seoul Paik Hospital and had followed more than two years were included in this study. The clinical result was evaluated by Harris hip score. The mean Harris hip score was 48 points preoperatively, 88 points at final follow-up, a mean of 3 years after revision. In radiological evaluation, osseous union between grafted bone and host bone was seen within 4 months in thirty two hips (89%), a complete grafted bone-cement radiolucent line of two millimeter or more in at least one zone was seen in seven hips (19%) and acetabular component migration was seen in six hips (17%) at postoperative 3 year follow-up radiograph. At the time of follow-up, five hips (14%) had been revised a second time: three for aseptic acetabular loosening, two for infection. In conclusion, we recommend the technique using allogenic chip bone graft and cement to reconstruct the acetabular bone deficiencies in revision total hip arthroplasties, though other technique will be recommend in severe segmental acetabular deficiencies or previous infection.

Clinical Analysis about the Injuries of Tendons , Vessels and Nerves in the Wrist / 대한정형외과학회잡지

The wrist joint is exposed to trauma easily which is a small portion of human body. Because there are many structures(tendons, vessels and nerves) in the wrist, it is necessary to examine carefully and treat properly when it is damaged. We have treated 230 cases of soft tissue injuries around the wrist and the result can be summarized as follows; 1. Among the 230 cases, the male ratio was 85% and the highest incidence was in the third decade. 2. Right side injuries were more than left and flexor surface injuries were more than extensor surface. 3, The main cause of injury was glass, 149 cases(64.8%) and the next on was knife, 37 cases(16%). 4. Injuries in the night were more than daytime. 5. Injuries in the summer were more than winter.
