We studied the degenerative changes of acetabulum, examining the acetabular articular cartilage at weight bearing dome area from the hips of 25 avascular necrosis of femoral head cases. Histological- histochemical studies demonstrated 4 mild, 19 moderate and 2 severe grade of degenerative arthritic change. This has confirm that even in early stage of avascular necrosis of femoral head, there are degenerative arthritis in acetabular cartilage. This may influence the prognosis of bipolar hemiarthro- plasty in avascular necrosis of femoral head patient.

It is indispensable to cover the skin defect when bone or tendon is exposed. In case of inevitable amputation of an extremity, it is possible to harvest a free flap from the amputed limb for providing coverage of the other wound. This technique allows immediate wound coverage without the morbidity of an additional donor site. We experienced an electrical burn case with inevitahle wrist disarticulation and successfully treated soft tissue defect of ankle using free vascularized flap.

The pedicled fillet flap concept has been successfully applied in both the upper and lower extremities for the treatment of difficult wound. In cases of inevitable extremity amputation, the transfer of pedicled flap from the amputed part is possible. In such substance, it is possible to obtain the pedicled fillet flap from the amputed limb to provide stump coverage. We experienced two cases of below-knee amputation due to severe flame burn which the stump was covered with island pedicled sole-fillet flap.

The purpose of this study is to evaluate the influence of the extent of involvement in the results of cementless THA in patients with idiopathic AVN of the femoral head. We reviewed 70 hips (52 patients) who had undergone cementless THA for idiopathic AVN of the femoral head. Anatomic femoral components were used in 43 hips and Harris Galante porous prosthesis were employed in 27 cases. The hips were classified according to International Classification (Association Research Circulation Osseous). The length of the follow-up period ranged from 3 to 5 years (average 53.5 months). Preoperative and postoperative clinical documentation and radiographs were evaluated. Statistical analysis was performed on the results of three analysis groups (Group A, comparison of results among Stage IIIA, IIIB, IIIC, and IV; Group B, between stage III and IV; Group C, between IIIA+IIIB and IIIC + IV). Of the 70 hips in the present study, there were 47 hips in stage III (IIIA, 15; IIIB, 19; IIIC, 13) and 23 hips in stage IV. The average postoperative Harris hip score at the time of study was 91.5 (Analysis Group C, p=.009). Femoral subsidence of more than 5 mm occurred in 5 hips (7.1%). Two hips were in Stage IIIC and three hips were in Stage IV (Group C, p=.024). The hips lower than -10 on Engh's index were present in one hip in Stage IIIC and three hips in Stage IV (Group C, p=.011). This study demonstrated that the clinical and radiological results of cementless THA were poor when the extent of involvement was greater or in the case of late stage subjects, particularly those above IIIC (p<05), with avascular necrosis of the femoral head.

To cover soft tissue defect, various types of flaps have been used. Although lateral supramalleolar flap has been used as rotation flaps or reversed island flaps to cover defects around the foot and ankle, there has been no report about its application as a free flap. The lateral supramalleolar island flap has proves to be supplied constantly by the terminal branch of the peroneal arterys perforating branch. The free lateral supramalleolar flap has the same skin territory. Its vascular pedicle can be extended to the main peroneal artery and vena comitans, which can be obtained by dissecting the peroneal vessels between the distal tibia and fibula through the interosseous membrane. We have successfully transferred this free flap in eight patients from April 1994 to February 1995. All of the patients had full thickness skin defects which were caused by contact thermal burn, electrical burn, flame burn or traffic accident. There were no complications. From our experience, we feel that this new free flap have some advantages, induding vascular anatomy and long pedicle with large diameter and a relatively thin flap with minimal morbidity of donor site.

In 1988, a new fascioutaneous flap, the Lateral supramalleolar flap, was introduced by Masquelet and Roman. The flap is designed on the lower third of the aspect of leg, and supplied by a cutaneous branch from the perforating branch of the peroneal artery. This perforating branch continues distally deep to the fascia along the anterior ankle and into the foot. This can be use as either proximally based rotation flap or distally based reversed pedicle island flap giving the flap an arc of rotation that allows coverage of the dorsal, lateral and plantar aspects of the foot, the posterior heel and the lower medial portion of the leg. The authors have recently used this flap for 13 cases of foot and ankle soft tissue defect reconstruction and all the cases, except two partial marginal necrosis, good postoperative course. In our opinion, this flap is useful for reconstruction of foot and ankle soft tissue defect which does not need nerve innervation. The main advantages of the flap are as follows 1. It may be a rather large flap(15× 9cm2 ). 2. The pedicle is long(8cm) and easy to dissect. 3. The pivot of the pedicle is distal(sinus tarsi) and allows great local possibilities of coverage. 4. It does not require the sacrifice of a main artery.
