We reviewed twelve cases of congenital dislocation of the knee(CDK) which treated at Keimyung University from January 1992 to January 1997. All case were type II dislocation according to classification suggested by Ferris and reduced with minimal treatment. Dislocation were reduced within 4 days in minimum after treatment and 3 weeks in maximum. The period of follow up ranged from 6 months to 5 years. Clinical results were good. Early diagnosis followed by conservative treatment is important and enough to treatment of the type II congenital dislocation of the knee.

Neurofibromatosis is a disease which involves both neuroectodermal and mesodermal tissue, and is characterized by cafe-au-lait spot, multiple subcutaneous neurofibromas, elephantiasis neuromatosa, a positive family history, and specific dystrophic osseous changes such as scoliosis, penciling of ribs, vertebral scalloping, a paravertebral soft tissue tumor, and congenital pseudarthrosis. The classic type of scoliosis in neurofibromatosis was known as a sharp localized short curve that is often rapidly progressive and produces severe deformity with dystrophic changes, but another form with long gentle curve is reported. Since conservative treatment is usually unsuccessful, posterior fusion with or without Harrington instrumentation is the treatment of choice even in young age when the curve is progressive. This paper was aimed to review our experience with 11 patients having neurofibromatosis and scoliosis, who were treated with posterior fusion and Harrington instrumentation from Jan. 1971 to Dec. 1980, and the results were as follows: 1. The average age that spinal deformity was observed was 7.7 years old, but the average age at treatment was 14.4. 2. Cafe-au-lait spot was observed in all cases, subcutaneous nodule in 7 cases, local gigantism in 2 cases, and positive family history in 3 cases. 2 cases were combined with congenital spinal anormalies. 3. Specific pattern in spinal deformity was not significant. There were 7 short curves less than 5 vertebrae involved and 6 long curves more than 6 vertebrae involved. 4. There were 5 kyphosis which had more than 50°, and those were usually combined with severe scoliosis. 5. Preoperative average degree of scoliosis was 93.8, and the final correction was 41.2° (43.9%) with loss of correction 5.3°(5.7%) after 3.2 year follow-up in average. 6. It shouid be educated for early detection at home and school, and for the importance of early treatment for the scoliosis, to prevent rapid increase of scoliosis in neurofibromatosis.

Basement membrane zone gene expression by fibroblast cultures was examined by molecular hybridizations with human sequence specific cDNAs corresponding to type 1V procollagen and laminin subunit polypeptides. Northern transfer analysis with total RNA revealed the presence of specific mRNA transcripts for al (IV) and a2 (1V) chains of type 1V procollagen as well as Bl and B2 chains of laminin. Laminin A chain mRNAs were not detected using the same RNA preparations. The molecular size of al (1V) and a2 (1V) procollagen mRNA revealed 6.8kb and 6.7kb, respectively. The molecular size of Bl chain of laminin revealed 5.6kb, and B2 chain revealed 8.2 and 5.5kb polymorphic transcripts. In slotblot analysis using densitometer, steady-state levels of type IV procollagen and laminin mRNAs indicated that they were in relatively low abunclance, as compaired with type I procollagen mRNA. Quantitative levels of al (IV) and laminin Bl chaii mRNAs were more abundant than those of a2 (IV) and laminin B2 mRNAs. The mRNA ratio of al (IV)/a2 (lV) and laminin Bl/B2 were 1.9 and 1.5, respectively. These results demonstrate evidence for differential regulation of the expression of different basement membrane zone molecules during the formation of basement membrane.

Osteochondromas are one of the most common benign bone tumors usually involving extraarticular metaphysis of long bone. Solitary intra-articular osteochondroma arising from the elbow joint has rarely been reported. We present a case of 23-year-old female who had pain and limited motion of the left elbow as a result of intraarticular osteochondroma of the distal humerus. Arthroscopic excision of the osteochondroma yielded complete relief of symptoms. Absence of recurrence was confirmed radiographically at two years after surgery. To the best of our knowledge, this is the first report of osteochondroma of the elbow successfully treated arthroscopically.

A clinical observation of 30 cases of pyogenic abscess and 18 cases of tuberculous abscess in the metaphysis of long bones during the past 15 years was carried out and following results were obtained. 1. The highest age incidence was the second decade (53.3%) in pyogenic abscess and the first decade (44.4%) in tuberculous abscess. 2. Average duration of symptoms were 1.6 years in pyogenic abscess and 2.3 years in tuberculous abscess. 3. Chief complaint on admission was pain both in pyogenic abscess (56.7%) and in tuberculous abscess (27.8%). 4. The tibia was the most common site in pyogenic abscess and the femur in tuberculous abscess. 5. Leucocyte count was increased more than 15, 000/mm in 23.3% of pyogenic abscess and 22. 2% of tuberculous abscess. 6. Erythrocyte sedimentation rate was increased more than 21mm/hr in 60.0% of pyogenic abscess and in 44.4% of tuberculous abecess. 7. Epiphysis was involved in 23.3% of pyogenic abscess and 38.9% of tuberculous abscess. 8. The positive result on bacteriologic culture was 46.7% in pyogenic abscess and 22.2% in tuberculous abscess. Coagulase positive staphylococcus aureus was cultured in 12 cases and other organisms were cultured in 2 cases. 9. Differential diagnosis between pyogenic, tuberculous abscess, and cystic tumors was not easy in many cases. Preoperatively, 5 cases of pyogenic abscess were misdiagnosed as tuberculosis and 2 cases as osteod osteoid osteoma. 3 cases of tuberculous abscess were misdiagnosed as pyogenics and 1 case as giant cell tumor. 10. Various methods of surgery including saucerization, curettage and bone graft, resection of bony focus, and arthrodesis were carried out. There was no difference in the end result between them. 11. Shortening or deformity due to epiphyseal plate damage was occurred in 3 cases (10.0%) in pyogenic abscess and 4 cases (22.2%) in tuberculous abscess. Those complications could be minimized with meticulous surgery not damaging the epiphyseal plate.

A clinical observation in 8 cases of multiple laminectomies under the age of 16 years who had been followed for more than 3 years was carried out to analyze deformities and its results of treatment, and the following results were obtained. 1. Spinal deformities were developed in 5 cases-4 kyphosis and 1 lordosis. 2. The kyphosis was developed in 1 case at cervical spine, 1 at thoracic, 1 at thoracolumbar junction and 1 at lumbar, and the lordosis was developed in 1 case at lumbar spine. 3. Anterior interbody fusion was carried out on two cases of kyphosis who had severe pain and neurological symptoms and posterolateral spinal fusion was carried out on one case of lumbar lordosis, with satisfactory results in all cases. 4. Since the incidence of spinal deformities following multiple laminectomies in children is high, laminectomy should be performed only when it is definitely indicated, and when it is done, damage to the posterior complex should be minimized. 5. For the prevention and treatment of the spinal deformities, brace or close observation should be necessary postoperatively, and spinal fusion should be performed in increasing or severe deformities.
