ABSTRACT
Notch stenosis had been thought to be related with anterior cruciate ligament (ACL) injury. The purpose of this study is to evaluate the possible relationship between notch stenosis and ACL injury. We measured the notch seen on the axial section in MRI at popliteal groove. We have retrospectively analyzed 116 cases of knee MRI. All cases were divided into three groups ; Group I were fifty six normal knee. Group II were thirty knee with contact ACL injuries. Group III were thirty knee with non contact ACL injuries. The result were as follows; 1. Statistically significant difference was found in the notch width index (NWI) between group I and group III but no significant differences was found in the NWI between group I and group II. 2. Statistically significant correlation to non-contact ACL injuries was found in the NWI at both anterior and posterior outlet of the notch. 3. An unique shape of the notch was found in the majority of group III.There seemed to be an obvious relationship between notch stenosis and non-contact ACL injuries.

Transient osteoporosis of the hip is a self-limited condition of uncertain etiology and pathogenesis that affects young and middle aged adults. Even its clinical features are similar to the features of osteonecrosis the prognosis and clinical end result are quite different. So differential diagnosis between the two is very important. We present a case of transient osteoporosis of the hip in middle aged man, which was completely reeovered after conservative treatment.

The main goals of surgical teatment of thoracolumbar vertebral fractures are to achieve reduction, stability and early, painless mobilization. A further aim is to avoid late malposition and to preserve mobility and lordosis. The main disadvantage of Harrington instrumentation and similar methods are that this device fixate five to seven vertebrae. The Cotrel-Dubousset(C-D) instrumentation provides a stable construct for fixation of spine fracture. The advantages of C-D pedicle screw for thoracolumbar spinal fractures are that compression or distraction force can be applied in the same rod and used to achieve anatomical reduction of spinal fractures and rigid fixation can be obtained with short instrumentation. The C-D instumentation was done for 15 unstable thoracolumbar spinal fractures at Seoul Red Cross Hospital from January, 1988 to January, 1990. The results were as follows. 1. The most common cause of the spine fracture was fall down, and majority are within 20-40 old age. 2. The most common involved site was T12 and Ll vertebrae (66.7%). 3. The most common type of injury was burst fracture by according to Denis classification(60%). 4. The complication was developed mostly in neurological deficient patient. 5. The advantage of the C-D instrumentation: (1) rigid and short osteosynthesis of spine fracture, (2) compression or distraction force can be applied in the same rod, (3) early mobilization with a brace is possible. 6. The rigid fixation can be obtained.

The mechanical derangement, developmental anomaly, infection amd tumor should be considered as a cause of low back pain in adolescents. Disc herniation in adolescents is very rare and some of that are due to fracture of the epiphyseal ring. We report a case of fracture of the first sacral epiphyseal ring simulating disc rupture.

Supracondylar fracture of the femur is not as common as the shaft fracture. There is wide range of potential complication in the treatment of these fractures and the method of the treament and the evaluation of it's result is variable and remains controversial. Until 1960, we believed conservative treatment supirior to the operative treatment of the supracondylar fracture of the femur. But recently, anatomical reduction and internal fixation with early joint motion showed satisfactory results and is the trend of treatment of these fracture. The authors of this thesis performed treatment of supracondylar fracture of femur by utilizing Ender nails and screws in 13 cases during the period from October 1987 to November 1988 and it was found that operation was relatively simple, bleeding was little and early exercise of knee was allowed and even for patients of old age internal fixation could be maintained easily.

Chondromalacia patella is a symptom complex characterized by aching pain behind the knee cap, retropatella tenderness that is aggravated by the stair climbing. Malalignment is an important factor causing chondromalacia patella. And to recognize it, is important in the diagnosis and treatment. We studied 3 parameters in the chondromalacic knee and nonchondromalacic knee and the following results was obtained. l. In nonchondromalacic knee, the sulcus angle is 141° 7′ and the congruence angle is −5° 1′ 2. In chonduomalacic knee the sulcus sagle is 139° 2′ and the congruence angle is +5° 3′ 3. In the group with abnormal congruence angle, there was much degenerative changes in the patellofemaral joint. So, it can be inferred that chondromalacia is a precursor of the osteoarthritis and the patient with abnormal congruence angle should be treated actively at the early stage if the conservative treatment had failed.
