Traumatic dislocation of the knee joint occurs very infrequently, but is one of the true emergencies in the orthopedic field. It is a serious injury, associated with extensive soft tissue demage and the danger of neurological and vascular involvement. There is a lot of theories about the mechanism of injury, the treatment and the incidence of complications. Generally they accept that in irreducible cases operative reduction is essential, but there is no uniformity of opinion on the treatment of the uncomplicated cases. This paper is based on 7 traumatic knee dislocations treated at Kang Nam Sacred Heart Hospital, Hallym College during the period from January 1980 till December 1984. The results of the study are as follows: 1. The patients are mostly injured due to the traffic accident and show even age distribution from twenties to fifties. 2. 5 cases out of 7, reduced at our hospital, were all anteriorly dislocated. 3. The posterior capsule and the posterior cruciate ligament were injured in all cases. 4. There were no significant differences between primary repair of soft tissues and the late reconstruction.

STUDY DESIGN: The operative treatment methods of twenty-one patients with Denis type B burst fractures were evaluated according to the level of pedicle screw fixation. OBJECTIVE: To compare the results of short segment pedicle screw fixation with long segment pedicle screw fixation in Denis type B burst fractures treated anteriorly with short bone graft. SUMMARY OF BACK GROUND DATA: Relatively good results(Short fusion time, good union rate, less loss of lordosis postoperatively etc.) were obtained in long segment fixation group during follow-up period. METHODS: Twenty-one patients with Denis B type burst fractures of thoracolumbar and lumbar spine were divided into two groups depend on the level of pedicle screw fixation in operative treatment methods, one group consisted of 10 cases which were treated by posterior short segment pedicle screw fixation and anterior interbody fusion with short bone graft(Group I : one level above and below posteior pedicle screw fixation of the fracture site and upper end plate of fracture site was fused with autogenous iliac bone or rib to adjacent vertebral body anteriorly through involved disc space) and the other groups consisted of 11 cases which were treated by posterior long segment pedicle screw fixation and anterior interbody fusion with short bone graft (Group II : more than two level above and below posterior pedicle screw fixation of the fracture site and additionally, anterior interbody fusion with short bone graft performed same as Group I). Bony union rate, union period, changes of height of bone and disc, kyphotic angle loss, interscrew angle and complications were measured using pre-, post-operative and follow-up radiographs and chart review. RESULTS: Comparing the two groups, there were no significant postoperative and follow-up results in both groups, especially, change of body & disc height, change of kyphotic angle and change of interscrew angle. However, relatively short fusion time, good union rate, less kyphotic angle loss, and low complication rates were obtainecl and maintained during follow-up period in long segment fixation lion group(Group II). CONCLUSIONS: Long segment pedicle screw fixation and anterior interbody fusion with short bone graft group could effectiyely treat Denis B type burst fractures of thoracolumbar & lumbar spine and maintain their postoperative results during follow up peroid.

3.A Clinical Study of the Children's Ankle Fractures with Growth Plate Injury

The fractures of the ankle in children are differ from those of adults in terms of the fracture pattern and the possibilities of influence to growth. The injuries of the ankle in children occur mostly at the bony structure rather than ligamentous structure, and some injuries of the growth plate may result in the arrest of entire growth plate or parts of growth plate and these may lead to leg length discrepancy or deformity. Many authors agree that the prognosis of injuries of the growth plate is dependent on the fracture type, the age of the patient at the onset of injuries, the degree of displacement of the fracture fragments, whether the injuries open or closed, and the efficacy of reduction. But the authors can not postulate one uniformed method of classification and treatment of the children's ankle fracture because of the variability of injuries. We have reviewed 35 cases of children's ankle fracture treated at our clinics from Dec. 1979 to Feb. 1984. The results obtained are as follows: l. Over half of the patients were between the ages of 13 and 16 years (54.3%). 2. The incidence of each type as Salter-Harris classification was that of type II(48.6%), type I(20.0%),type III(14.3%),type IV (8.6%). 3. The traffic accidents were the main causes of injury (68.5%). 4. The type I fractures occured mostly under 10 years of age and the type II fractures in adolescents. 5. All the type I fractures were treated conservatively without any complication, and the type II fractures were treated conservatively in 13 cases (76.5%) and operatively in 4 cases (23.5%) with variable results. 6. Overall incidence of complication was 20.0%, consisted with two cases of conservatively treated but not accurately reduced type II fractures, a conservatively treated type III fracture, a triplane fracture, and the others.

Chronic recurrent multifocal osteomyelitis is rare, its etiology is unknown, and it most commonly occurs during childhood or adolescence. It is characterized by an insidious onset of fever, local swelling and pain in affected bones, and radiological abnormalities suggestive of osteomyelitis. We experienced one case of chronic recurrent multifocal osteomylitis. The lesions were in tibia, radius.

Tibial Plateau fracture is relatively common injury which often produce major disability, and their treatment has been in controversy. Recent studies suggest that early knee motion and perhaps better surgical techniques have improved clinical end results. Protection from weight bearing and length of immobilization have varied among authors and variable treatment methods. Thirty-eight tibial plateau fractures treated at Kangnam Sacred Heart Hospital from March in 1984 to December in 1988 were analized and the followings were obtained. l. Of 38 patients, 29 patients were male and 9 female. 2. The most common associated injury was an ipsilateral fibular fracture. 3. Average duration of immobilization was 4 to 6 weeks in conservative treatment and 2 to 4 weeks in operative treatment. 4. We started partial weight bearing in 24 patients within 6 weeks and full weight bearing in 28 patients between 8 and 12 weeks, and good end results were obtained.
