The authors investigated LD activity and isoenzyme of total serum and joint fiuid in 18 cases of rheumatoid arthritis, 11 cases of degenerative arthritis, 6 cases of traumatic arthritis, and 10 cases of healthy control. The samples of serum examined were obtained from the anterior cubital vein and joint fluid from the knee joint except 2 cases of the rheumatoid arthritis, which were obtained from the wrist joint, in Busan National University Hospital from the April to July 1981. Total serum LD activity was measured by method of Caboud-Wroblewski and isoenzyme fractions were analysed by cellulose acetate electrophoresis. The results obtained were as follows: l. In the patients with joint diseases, total serum LD activity was significantly increased than that of healthy control. 2. The LD1 isoenzyme of joint fiuid was increased in degenerative arthritis than that in rheumatoid arthritis, and LD3 and LD5 isoenzymes were significantly increased in rheumatoid arthritis than that in degenerative arthritis. 3. In correlation between total LD and LD isoenzymes activities in joint fluid, total LD activity of rheumatoid arthritis was correlated with decrease of LD1 isoenzyme and increase of LD5 isoenzyme activity, and total LD activity of the degenerative arthritis was correlated with increase of LD1 isoenzyme activity. 4. In correlation between isoenzyme activity and gamma globulin of joint fluid, LD3 and LD5 isoenzyme activity in rheumatoid arthritis and LD4 in degenerative arthritis was correlated with increase of gamma globulin.

Hips with residual subluxation after treatment of congenital dislocation of the hip in children who were admitted in department of orthopaedic surgery, Pusan National University Hospital, from January 1980 to October 1987, are investigated with clinical data, X-ray findings, classification and treatment. Hips with residual subluxation after treatment were followed most commonly by closed reduction and cast immobilization, 15 cases, and by innominate osteotomy, 5 cases. Conservative methods as broom-skick cast or abduction brace were done for the treatment of residual subluxation in all cases, except 2 cases of femoral osteotomies. Degree of improvement was determined by periodically measuring C–E angle, acetabular index, migration percentage and the distance from tear-drop to medial metaphysis of proximal femur. The results were as follow :1. Hips with residual subluxation after treatment were found most commonly after closed reduction and cast immobilization. 2. Residual subluxation was classified as Grade Zero to Grade three by measuring the distance from tear-drop to medial metaphysis of proximal femur. There was 12% of Grade I, 48% of Grade II and 40% of Grade III. 3. The mean normalization periods from Grade I to normal, from Grade II to normal, from Grade III to normal, were 14.7 months, 26.3 months, 37.1 months, respectively. 4. Thirteen cases which more than one and half years of follow-up were possible showed improvements in acetabular index from 30.5°to 22.9°, C–E angle from 5.7°to 25.4° and migration percentage from 34.4% to 18.8%, 5. There were relatively poor results in the hips with residual subluxation after innominate osteotomy.

We, at Department of Orthopedic Surgery, College of Medicine, Pusan National University, applied epiphyseal distraction as a method of limb lengthening, using unilateral one-plane pin fixator(ORTHOFIX) and bilateral multi-plane ring fixator(SEQUOIA) to three children with limb length discrepancies and angulation deformity due to injury of epiphyseal plate, and obtained following results. l. At first case, on whose distal femoral physis, bone bridge occupied about 20% of total epiphyseal plate and distributed mainly on the lateral side. At 10 days of distraction, epiphysiolysis occurred from the lateral side at first and angulation deformity was corrected. Epiphysiolysis on the medial side of physis appeared apparently after 60mm distraction. Bone lengthening of 4.2cm and correction of 25 valgus deformity were achieved after 72mm distraction for about 10 weeks. The percentage of increase in the initial length achieved was 11.67% and healing index was 27.86. 7 months later, loss of lengthening of 2.7cm was observed and it was considered that this was due to relatively short corticalization phase. 2. At second case, on whose distal tibial physis, bone bridge occupied about 40% of total epiphyseal plate and distributed on the medial side. At 10 days of distraction, epiphysiolysis occurred on the medial side of the epiphyseal plate, but not on the lateral side and instead of further lengthening, valgus deformity of the ankle appeared. It was thought that asymmetric distraction was attributed to the difference between the force applied on the medial side and that applied on the lateral side of the epiphyseal plate by unilateral one-plane pin fixation. 3. At third case, on whose distal tibial physis, bone bridge occupied about 75% of total epiphyseal plate. No epiphysiolysis occurred. there was a difficulty in observation of epiphysiolysis because ring fixator was overlapped with the epiphyseal plate on radiographs.

The sequential use of ⁹⁹mTc-methylene diphosphonate(⁹⁹mTc-MDP) and ⁶⁷Ga imaging is thought to be useful to diagnose acute hematogenous osteomyelitis, and to determine whether it is active or inactive in chronic osteomyelitis. We compared the results obtained by the sequential use of ⁹⁹mTc-MDP and ⁶⁷Ga imaging with those obtained by the surgical culture and biopsy in 31 patients who were supposed to have the osteomyelitis and admitted to Pusan National University Hospital from July 1987 to July 1989. The results were as follows:l. According to the diagnosis at discharge, 4 cases were normal, 20 cases active osteomyelitis, and 7 cases inactive osteomyelitis. 2. Four normal cases were negative both with ⁹⁹mTc-MDP and with ⁶⁷Ga. Twenty cases of active osteomyelitis showed positive results both with 99mTc-MDP and with ⁶⁷Ga. And of 7 cases of inactive osteomyelitis, 6 cases showed positive ⁹⁹mTc-MDP and negative ⁶⁷Ga, 1 cases was negative both with ⁹⁹mTc-MDP and with ⁶⁷Ga. 3. It is suggested that in active osteomyelitis both ⁹⁹mTc-MDP and ⁶⁷Ga were positive, in inactive osteomyelitis ⁹⁹mTc-MDP positive and ⁶⁷Ga negative and in normal or wastive ostemyelitis both ⁹⁹mTc-MDP and ⁶⁷Ga negative. 4. The sequential use of ⁹⁹mTc-MDP and ⁶⁷Ga imaging was particularly useful to diagnose acute hematogenous osteomyelitis in the case of the obscure diagnosis and supposedly normal radiological finding and to determine whether chronic osteomyelitis is active or complicated by an acute flare-up.

Soft tissue reconstruction of the hand remains a challenge for the hand surgeon, who must choose whether to use a local flap, a distant flap or a free flap. Local flaps, derived from tissue immediately adjacent to the primary defect, are the first choice. But there is a shortage of skin in the hand and there are regions of the hand that should not be used as donor sites since cover of the resultant secondary defect with a skin graft would be inappropriate. We used island flaps for the small soft tissue defects in the hand which were difficult to cover with a conventional skin graft or local flap. The results were as follows; 1. The causes of the soft tissue defects were traumatic amputation in 4 cases, camptodactyly in 4 cases, replantation in 3 cases, infection in 3 cases and tumor in 1 case. 2. The sites of the soft tissue defects were thumb tip in 6 cases, fifth finger PIP joint volar aspect in 3 cases, index tip in 2 cases, thumb volar and dorsal surface in 2 cases, third and fourth MP joint dorsal surface in 1 case, fourth finger PIP joint volar aspect in 1 case and first interdigital web space in 1 case. 3. The donor flaps were fourth finger neurovascular island flap in 8 cases, reverse dorsal matacarpal flap in 5 cases and first dorsal metacarpal artery flap in 4 cases. 4. The sizes of the flap were from 1. 0×1. 5cm to 2.0×4.0cm and and average of 1.5×2.0cm. 5. The flaps were survive completely with a touch sensat,ion except 2 cases which were covered by reverse 5th dorsal metacarpal flap.
