1. Two hundred and fifty cases of fractures of the tibia treated at the orthopedic department of the Catholic Medical College during period of January, 1966 to September, 1971 were subjected to analysis. 2. The evaluation was done according to the classification of Ellis. Among 250 cases of the tibial fractures 120 being mild grade, 63 moderate grade and 67 severe grade. 3. Of 6 groups, 1st group was treated with toe to groin cast, 2nd group was treated with functional below the knee cast, 3rd group was treated with pin & plaster, 4th group was treated with 1–2 screw fixation & wiring, 5th group was treated with plate fixation and 6th group was treated with intramedullary nailing. 4. The healing time is almost proportional to the severity of the fracture grade and also the better prognosis largely depends on the mild grade. 5. We experienced 9 cases of non-union (3.6%), 19 cases of delayed union (7.6%) in most of moderate and severe grade.

2.Vascular Injury of Lower Extremity

Blunt trauma severe enough to cause fracture of the long bones of the lower extremity may seriously damage adjacent arteries either by direct or indirect force. Diagnosis of disruption or thrombosis by this combination of injuries, is frequently delayed until the opportunity to salvage the extremity is lost. This error will result in an excessively high amputation rate. From September 1971 to August 1972, six Cases with or without fracture were treated at the Orthopedic Department of the Catholic Medical College. Of these six, three resulted in amputation by losing the chance to make the early diagnosis of injury.

5.Treatment of Fracture of Shaft of Humerus by Ender Nailing

The Journal of the Korean Orthopaedic Association 1994;29(6):1597-1601
Authors presented the experience of Ender nail treatment for the humeral shaft fractures in 24 patients. The results of treatment in all were satisfactory, though there were four cases of delayed union. Bridging callus was formed at 8.2 weeks on an average. The average clinical union time was 14 weeks. No complications developed during nailing procedure. A case of radial nerve palsy after fracture recovered spontaneously. Longer nails which hit the end of medullary canal of distal fragment distracted the fracture gap, and resulted in delayed union in 4 cases. Therefore, it is recommended to use the proper size of nail to avoid the distraction effect of the inserted nail, and to use two nails at minimum for better fixation. However, when intramedullary Ender nailing is properly done, single nailing also can give consistently good anatomic and functional results.

The authors did clinical analysis for 37 cases, ranging from 5 to 13 year old of age and following result obtained. 1. In group I partial involved type had brightful prognosis even in the neglected the cases. 2. Ischeal brace did not give any help to group II & III but in group I, it gave some help to the prognosis. 3. In untreated cases of old age group developed early arthritic changes. 4. The inital radiological bony changes in early L-C-P. cases was the demineralization of the subchondral area and subsequently subohondral vaccum phenomena followed.

Congenital dislocation of the hip has been known as one of the most common congenital anomalies in the orthopedic field since the time of Hippocrates (460-357 B.C.). The occurence of C.D.H. in twin babies is extremely rare thus few if any papers have been reported. During the period of January 1971 through June 1976 the authors have treated a total of 49 cases as inpatients. Two of these were twin babies. In both cases the hip was surgically reduced and followed by open reduction and femoral derotation osteotomy. Clinically and radiologically the results were good during the duration of follow-up seven months after operations.

Subtrochanteric fracture is well known for its difficulty in management, though various devices of rigid fixation have been developed. Each internal fixation device requires a lot of surgical instruments and the surgeon must be skillful in using them. Osteo self-compression plate which was preoperatively bent to fit the contour of the lateral surface of the subtrochanteric region was proved to be technically easy to fix these fractures without causing major complication. Present authors recommend to use this prebent Osteo self-compression device to treat this fracture when the surgical instruments are not fully equipped, and suitable fixation devices are not available, and/or the surgeon has no experience in handling the newly developed surgical instruments for the subtrochanteric fracture.

To evaluate the value of MR imaging in the examination of ligament injury of the knee, we retrospectively analysed the MR images of 61 injured knees of 60 patients. The presence of tear was determined by arthroscopy in all cases. Anterior/posterior cruciate ligaments(ACL/PCL) were demonstrated by sagittal images. Media/lateral collateral ligaments(MCL/LCL) were evaluated on coronal images. The diagnostic accuracy were 91.8%, 96.7% and 100% for ACL, PCL and MCL, respectively. The specificity for the lateral collateral ligament was 100%. It is concluded that magnetic resonance imaging is an accurate method in detecting injury of the ligaments of the knee.
