Fracture of the femur during total hip arthroplasty presents the simultaneous problems of prosthetic stability and fracture treatment. The treatment of such fractures can be complex and is one of the major challenges and this complication is associated with a high morbidity and a significant delay in convalescence. Among the 237 cases, who were treated by cementless total hip arthroplasty from Jan. 1986 to Dec. 1992, 13 cases of femoral fracture were experienced. They usually occured during insertion of prosthesis and preparation of the medullary canal. There were 6 cases of type II fracture, 1 case of type III fracture, 5 cases of type IV fracture and 1 case of type V fracture according to AAOS classification. All of the fracture healed, but the prognosis of these cases must be determined by follow up. We recommend that femoral fractures can be prevented by accurate preoperative evaluation of the size of the femoral canal, identification and management of the predisposing factors for intraoperative fractures.

BACKGROUND: Although palmoplantar epidermal cysts have long been associated with develop ment following implantation of an epidermal fragment as a result of a penetrating or blunt injury, the pathogenic mechanism is still not fully understood. Since 1987, many cases have been reported in which human papillomavirus(HPV) could be associated with palmoplantar epidermal cysts. OBJECTIVE: In this study, we evaluated the clinicopathological findings of palmoplantar epidermal cysts and investigated them for the presence of HPV in order to examine the role of HPV in the pathogenesis of this disorder in Korea. METHODS: The clinical, histological, immunohistochemical studies were performed on seven cases of plantar cysts, and two cases of palmar cysts. RESULTS: No previous trauma history was seen. Histopathologically, parakeratotic nuclei, or vacuolar strutures within the keratinous mass in the cyst cavity were found. However, we could not find intracytoplasirnic eosinophilic bodies in the wall, the cyst content, or the overlying epidermis. The dyskeratotic keratinocytes were observed in 3 cases. Papillomavirus common antigens were not detected by immunohissochemical staining. CONCLUSIONS: Palmoplantar epidermal cysts in Korea have some different histological features compared to those of HPV 60-associated cases in Japan and we could not detect the immunohistochemical evidence of HPV infection in our cases.

Methods of treatment of Legg-Calve-Perthes' disease, (L.C.P.D.) are at present generally defined, and the individual approach is now more precise than before. But it is still controversial, particularly in older age groups. We analized the result of intertrochanteric varus osteotomy in 44 hips and innominate osteotomy in 23 hips of L.C.P.D., and compared the former with the later. To find out the influence of the both osteotomies on the femoral head (coxa magna), the relations between the stage and degree of involvement at operation and reult, and the postoperative progression of disease, the cases were analyzed and classified by Elizabethtown's stage and Catterall group. And also the duration of fragmentation stage after osteotomy was observed. Results were as follows: l. At the time of operation 45 hips were in avascular stage, 18 hips in fragmentation stage, and 4 hips in healing stage. 20 hips(29.8%) were classified as group II, 29(43. 3%) group III, and 18(23.1%) group IV. 2. After the osteotmy in case of avasculsr necrosis stage, average duration of fragmentation stage was 6.3 months after femoral osteotomy and 1 year 6 months after innominate osteotomy. 12 among 20 hips were skipped the fragmentation stage, and got into healing stage in case of femoral osteotomy. 3. After the osteotomy at the fragmentation stage, average duration of the fragmentation stage was 9.8 months after femoral osteotomy and 1 year 3 months in case of innominate osteotomy. 4. Regardless of the type of osteotomy, coxa magna was observed more frequently in the case who had surgery at the late stage and severely involoved head at the time of osteotomy. 5. In the case of femoral osteotomy, average preoperative neck shaft angle was 138.5°, and postoperative one was 113.5°. During the follow-up study, 12.0° of revalgarisation took place. 6. The result obtained by femoral osteotomy gave better results than those by innominate osteotomy. Regardless of the type of osteotomy, good results were obtained in case who had surgery at the early stage such as avascular stage, and had mild involvement as such group II.

Arthroscopic anterior cruciate ligament reconstruction with bone-patella tendon-bone has been commonly using for ACL insufficient patients. Bone-patellar tendon-bone graft is a strong intra-articular substitute, which allows, by means of its bony end, a rigid fixation with early bone to hone healing. As a counterpart, potentially serious cornplications & donor site morbidity has been reported, such as patella fracture & patella tendon avulsion, anterior knee pain, patella tendinitis, dcmor site pain and bone defect. We suppose tightly packing the donor site bony defect with hetrograft (Lubboc) may be also useful. So, we analyzed the morphological change in bony defect and donor site morbidity between the group of non-replaced bony defect and the group of replaced bony defect using by heterograft (Lubboc). We replaceJ hetrograft into the patellar side bony defect in 15 knees and left alone in l5 knees. The average follow up period was 17 months. The results werc as follows: 1. Nearly norma1 appearance on the bony defect showed at the long tenn follow up roentgenogram in the group of replaced hetrograft, but scalloping on the pateltar bomp defect was seen in non-replaced group. 2. Donor site morbidity (pain or patellai tendinitis) was developed 8 knees in the replaced group, and 7 knees in the non-rep)aced group. 3. We conclude that the filled in the bony defect hy hone graft (heterografl:) can not decrease the donor site morbidi ty.
