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.

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.

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 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.

A case of fibrolipomatous hamartoma of the median nerve in the palm and digits of the hand in a 14 year old man developed in the right hand is reported. This is rare disease characterized by fatty and fibrous tissue infiltration in themedian nerve of the palm and digits. This case was treated by limited debulking of the redundant tumor tissue and excision of the transverse carpal ligament. This case was performed with relief of the symptom.

Benign solitary osteochondroma are the most common benign bone tumor, and often arise in the long bone of the extremities about 80% of lesions, particulary about the knee and the upper extremity. In rare cases, the spine is involved. We describe a case in which a solitary sacral osteochondroma compressed the lumbosacral plexus, producing sensory disturbance. The tumor was removed through the anterior midline approach. The excised mass was round, lobulated, measuring 7. 5cm×6cm, pedunculated type and the cartilage cap is complete and is 4mm in thickness.
