During the period from Jan. 1983 to May 1986, 36 knees of 36 patients underwent clinical evaluation, arthrography and arthroscopy. We performed 2 total open meniscectomy, 4 partial open meniscetomy, 12 arthroscopic partial meniscectomy. In the studied group, there were 13 tears medial, 16 tears of lateral and 7 tears of discoid meniscus. Statistical analyses were as follows 1. Male was affected 6 times more than female. The meniscal tears occured in the age group between 10 and 20 years old (67%). 2. The lateral menisci were affected 1.8 times than the medial. 3. The general diagnosis of torn meniscus for the 36 knees was correct by clinical evaluation for 22 (61%), by arthrography for 25 (61%), by arthroscopy for 34 (94.5%). 4. The patients who had taken arthroscopic meniscectomy had shorter hospital stay, rapid convalescence and low postoperative complication or morbidity. 5. At mean follow up of 7.2 months, 72% were rated excellent or good result.

Now, incidence of tibial plateau fracture so called bumfer fracture is increasing because of development of industry and traffics. This fracture has some problems such as involvement of important weight bearing joint, uncertain prognosis, difficulty of diagnosis and treatment about soft tissues injury into the joint and operative indication. For the purpose of studying the problems, we analysed 24 cases of fractured tibial plateau, who admitted to CNUH Orthopaedic dpt. during 5 years from Feb. 1981 to Feb. 1986. We concluded such as 1. Sex and age distribution was male (83%) and middle age (75%) predominant. 2. Traffic accidents (84%) were main cause of fractures. 3. Along the Hohls classification, comminuted type (Type Ⅵ) was predominant (33.5%). 4. The rate of associated injuries were high (66.7%). 5. Associated soft tissue injures into the joint were 6 cases (27%), showed usually the poor prognosis. 6. Results of the operative or nonoperative treatment were nearly same but poor open reduction and internal fixation compared to nonoperative treatment was worse prognosis.

Articular cartilage is avascular and have dual functions of shock absorber and bearing surface in a moving joint. It is known that alteration of synovial-fluid perfusion causes degeneration of articular cartilage because the chondrocytes in mature adult must receive their nurishment solely from synovial fluid perfusion. Now, in orthopedic fields, the traction is it popular use, and to study the cartilage changes induced by this long term traction, the lateral femoral chondyle was resected about 1 cm from knee joint line in rabbits, and serial histologic examination of articular cartilage was done during 5 weeks. The results obtained were as followings ; 1. The degenerative changes of articular cartilage were observed at 1 week after condylar resection. 2. The severity of the histologic changes appeared to be related to the duration of condylar resection. 3. Vascular invasion to the calcific cartilage zone was begun from 3 weeks after condylar resection and degree of vascular invasion was increased with the duration of condylar resection. 4. Subchondral osteoporosis was begun 3 weeks after condylar resection and severity of osteoporosis was increased with the duration of condylar resection.

도재소부전장관에서 금속이 노출되지 않고 도재만이 파절시, 구강내에서 직접 행할 수 있는 심미적 수복 방법으로서 복합성 수지를 이용한 수복 방법이 널리 이용되고 있는데 본실험의 목적은 도재와 광중합성 수지간의 접합강도를 비교 측정코저 함에 있다. 본 실험에서는 주사전자 현미경을 사용하여 도재의 부식액 (5% 불화수소산용액, Excelco's porcelain etching gel) 및 부식 시간(2.5분, 5분, 10분, 20분)에 따른 부식양상을 먼저 관찰하였다. 그다음 각기 다른 시간에서 부식 처리된 도재와 대조군으로서 미부식 처리된 도재에 광중합성 수지를 부착시킬시, 첫째 Silane coupling agent(Scotch-Prime)도포후 광중합성 수지를 결합 시켰고 둘째 bonding agent(Scotch bond)도포후 광중합성 수지를 결합시켰으며 셋째 Silane coupling agent(Scotch-Prime)에 bonding agent(Scotch bond)를 도포후 광중합성 수지로 결합 시킨후, 인장강도 측정기 (Shimadzu universal testing machine)를 사용하여 결합력을 측정한 결과 다음과 같은 결론을 얻었다. 1. 부식처리된 도재가 미부식 처리된 도재 보다 결합력이 높았다. (p<0.05, P<0.001) 2. 부식 처리된 도재나 미부식 처리된 도재에 있어서 silane coupling agent 도포후 bonding agent로 처치한 경우 가장 결합력이 높았으며 그다음 silane coupling agent로 처치한 경우, bonding agent로 처치한 경우의 순이었다. 3. 도재부식 시간의 증가에 따른 결합력의 차이는 5% HF용액으로 부식 처리된 도재와 Excelco로 부식 처리된 도재에 있어서 5분 정도 까지는 결합력의 증가를 보였으나 그 후에는 결합력에 있어서 거의 증가하지 않는 양상을 보였다. 4. Excelco로 부식 처리된 도재와 5% HF 용액으로 부식처리된 도재간의 결합력 차이에 있어서 bonding agent만으로 처치한 경우에는 두결합력 사이에 서로 유의한 차이를 보이지 않았으나 (P>0.5) silane coupling agent만으로 처치한 경우와 silane coupling agent 도포후 bonding agent로 처치한 경우에는 두결합력 사이에 서로 유의한 차이를 보였다. (P<0.05, P<0.001) 5. Excelco로 부식처리된 도재가 5% HF 용액으로 부식처리된 도재보다 부식정도가 더 현저하였다.

강직성 척추염에 대한 연구 : 척추 골절을 중심으로 Focused in Spine Fractures

In ankylosing Spondylitis, ankylosis of some or all segments of the spine, segmentally or diffusely can be affected. Because all the ligaments become ossified in the involved area, a fracture that occur through this involved segment traverses both bone and ligaments, producing an extremely unstable situation similar to a shearing type of fracture. As the disease enters a chronic phase, the pathologic changes lead to a rigid, brittle, and osteoporotic spine. Mild trauma can lead to fractures that are difficult to diagnose, cause a high incidence of neurologic deficits, and present treatment problems. Patients known to have ankylosing spondylitis should be counseled regarding the possibility of a fracture, and if pain persists after an injury, they should be thoroughly investigated radiologically to rule out a potentially serious problem. Reduction of the displacement and stabilization is best achieved with posterior instrumentation, and laminectomy is not indicated. From March, 1990 to October, 1996, 11 cases of the ankylosing spondylitis in the department of orthopaedic surgery at Chungnam National University Hospital were managed nonoperatively with good healing and one case is operatively treated by anterior interbody fusion for cervical lesion, posterior instrumentation for thoracolumbar lesion.

A posterolateral intertransverse process fusion is generally considered to be one of the most common types of lumbar fusion and a reliable procedure. It is reported that establishment of blood supply is important for nutrition as well as for formation of new bone during bone graft healing. Since the major interosseous blood supply for vascularization of autogenous bone graft is originated from the upper and lower transverse process, the one of the transverse process can be related to rate of bony union. In fact, there were some reports on difference in fusion rate although very few on comparison of union rate of posterolateral fusion of isthemic spondylolisthesis with that of degenerative spondylolisthesis. It can be constructed that different union rate can result from the differences in transverse process areas among isthemic and degenerative spondylolisthesis cases. In this study, the area of the transverse processes of L3-5 were measured in isthemic and degenerative spondylolisthetic spines. For this purpose, Ushikata area-Curvimeter (X-PLAN 360) was used. Results surgested that there were no significant differences within the gender and the type of spondylolisthesis

We have treated 38 cases of the injuries of the Thoracolumbar spine (T11 to L2) by short segment pedicular screw fixation using C-D instrumentation during the period from May. 1989 to June, 1993. The results were obtained as follows. 1. The Correction after short segment fixation was satisfying as follows : Ant. wedging angle, 11.3 degrees. Local Kyphosis angle, 11.1 degrees. Ant. vertebral height, 31.7%. Post. vertebral height, 6.6%. 2. The maintaing of correction appeared to be satistying as well, correction loss was follows : Ant. wedging angle, 2.2 degrees. Local kyphosis angle, 1.7 degreees. Ant. vertebral height, 6.2%. Post. vertebral height, 1.8%. 3. The short segment fixation with CD instrumentation was effective in correction, its maintance and no neurologic deterioration
