Author take off the pelvic bone from the cadaver and made the accruate reconstructed the pelvic bone as well as normal bone. Then author setted the pelvic bone into the specialized acrylic globe as the normal person erect position. For the acetabular posterior wall, projected the radiologic beam from the 0°to 45°cephalad direction and then pelvic bone rotated internally 0°~45°, each section is 5°. For acetabular anterior wall, projected the radiologic beam from 0° to 45° caudal direction and pelvic bone rotated externally 0°~45°, each section is 5° too. From the pelvic bone experiments, author get on the good radiologic angle for acetabular anterior and posterior wall. Ane then make the radiologic projection for normal person as the pelvic experiment. In pelvic bone model experiment, For acetabular anterior wall and anterior colum, external rotation 20°~30° caudal tilting 30°~45° angle projection has good visualization. For acetabular posterior wall and posterior column (including anterior column partially), internal rotation 15°~20° cephalad tilting 15°~30°angle projection has the good visualization. In normal person experiment, For acetabular anterior wall and anterior column, external rotation 20°caudal tilting 30°angle projection shows the good visualization. For acetabular posterior wall and column (including anterior column partially) internal rotation 20°cephalad tilting 30°angle projection shows good visualization. From the pelvic bone model and normal person experiments, the following conclusion are obtained. 1. For posterior wall and posterior column(including anterior column partially), internal rotation 20°, cephalad tilting 30°view is good. 2. For anterior wall and anterior column, external rotation 20°, caudal tilting 30°view is good.

Segmental fractures of the femoral shaft result from high energy trauma such as a traffic accident or falls, and it is frequently accompanied by multiple fractures and severe injuries to other organs. Thus it is very difficult to treat these fractures satisfactorily and several complications can be caused. Early operative intervention and rigid fixation is important to mobilize the patient and to ensure early rehabilitation. Nineteen cases of segmental fractures of the femoral shaft were treated with operative intervention(intramedullary nailing) and followed up between May 1989 and Nov. 1993.; minimal follow-up period was more than one year. Results were obtained as follows: 1. The methods of treatment were interlocking intramedullary nailing in 16 cases(colsed nailing in 7 cases, open nailing in 9 cases) and Kiintscher nailing in 3 cases. Bone grafts were done in 11 cases among 19 cases(8 cases in the interlocking nail group). 2. The closed interlocking intramedullary nailing could be obtained in more shortened operation time than in the open method. 3. There was earlier bone union time in the closed intramedullary nailing than in the open method with bone graft, but there was no statistical significance(SPSS/pc+progam). 4. There was a tendency of earlier bone union time in the proximal fracture site than in the distal fracture site.

46 knees with injured meniscus diagnosed by the use of history and physical examination as well as by arthrography were meniscectomized from January in 1974 to June in 1978. Statistical analysis of data obtained from the histories, physical examinations and arthrographic studies of 46 knees with a mean follow up 6 months after meniscectomy revealed as follows. 1. Lateral meniscus injuries were higher incidence than medial meniscus. 2. In the posterior horn of the medial meniscus and in the middle third of the lateral meniscus on the injured location were more frequently encountered. 3. To compare the results of twe methods of diagnosis were obtained with 67% accuracy by the use of history and physical examination and with 85% accuracy by arthrography 4. We should be able to diagnosis with 91% armed with a history and physical examination and an arthrogram. 5. As being the excellent results after meniscectomy were classified with 78%.

Pyogenic vertebral osteomyelitis is rare. It most commonly occurs at the lumbar area and in the fifth to seventh decades of life. Most individuals present with back pain, abdominal pain, hip pain and meningeal syndrome. We experienced three cases of unusual patterns of pyogenic osteomyelitis. The first case developed after sepsis. The second case developed after open fracture and infection of other site. The third case was misdiagnosed as metastatic cancer. We present these cases with a brief review of literatures.

The anterior cruciate ligament injury is one of the most common ligament injury of the knee joint, and anterior cruciate ligament is as important structure for stabilization as a primary restraint. Noyes reported that the diagnosis of a tek of the anterior cruciate ligament was made by the original treating physician in only 6.8%. And there are many controversies in its treatment. It is certain thatearly diagnosis and treatment are th most important clue. Authors studied 48 patients of isolated anterior cruciate ligament injury who were diagnosed by same physician from Jan. 1983 to Dec. 1985 after follow ups ranging from six mnths to 4 years, average beimng one year and two months. The results were as followings: 1. The most common cause was sports injury. 2. The most common sign and symptom were hemarthrosis in acute injury and giving way in chronic injury. 3. Anterior drawer test without anesthesia had 25% of diagnostic accuracy but pivot shift test under anesthesia 95.8%. 4. 31 cases in 48 cases (64.8) had associated meniscal injury. 5. In acute torn ACL, the primajy repair was preparable but conservative treatment with arthroscopic partial menisectomy was eful in chronic case.

PURPOSE: In order to know the clinical usefulness of the Bioscrew(Linvatec, USA) and the Semi-Fix (Arthrex, USA) technique for femoral fixation in ACL reconstruction using hamstring double loops, we scrutinized and compared the 24 knees. Materials and Methods: We compared Lysholm score, Hospital for Special Surgery(HSS) knee rating scores, Lachman tests, Pivot-Shift tests and KT side to side difference in 24 knees after arthroscopic ACL reconstruction using hamstring double loops from August 1996 to January 1998. We have used fourteen bio-absorbable interference screws and ten Semi-fixs for femoral tunnel fixation. RESULTS: We took the data; the Lysholm score of 96.1 and 94.1; HSS score of 98.6 and 98.1; KT differ- ence of 1.3 +- 2.13(mm) and 1.2 +- 1.89(mm) after ACL reconstruction using Bioscrew or Semi-Fix respec- tively. Femoral tunnel enlargement showed 2.51 +- 1.03(mm) and 1.95 +- 2.33(mm) respectively. And we got the similar results of Pivot-shift test, Lachman test and anterior drawer test after reconstructive surgery. CONCLUSION: Since we got the similar good data in comparative clinical study between the Bioscrews and the Semi-Fix technique, we anticipatd that either the use of Semi-fix technique or the biodegradable interference screws would be bright in the fixation to femoral tunnel in ACL reconstruction using ham- string double loops.

A case of intraneural ganglion of the peroneal nerve in an eleven year old boy is reported. The cystic ganglion, 5.5cm×2.0×1.0cm, which was located at the region of the bifurcation of the peroneal nerve without communication of any joint or bursa, was excised, The ganglion was recurred at 6 weeks after the first excision.

During the last 18 years only a small number of successful replantation of lower extremities severed by trauma have been reported. In this paper we report the first successful case of replantation of completely amputated thigh In Korean literature. A 31-year-old man was admitted to Kyung Hee Unlversity Hospital on February 27th 1976, approximately 1 hour after accident in which the left thigh was completely amputated 15 cm above the knee joint. Circulation was restored 6 hours after amputation through anastomosis of the femoral vein, artery, great saphenous vein, profunda femoris artery and vein. The continuity of sciatic nerve was reestablished by secondary furnicular suture 7 week after injury. About 4 years and 7 months after injury the patient could walk without pain and returned to his occupation. Thre was a almost complete return of motor and sensory function of the posterior tibial nerve.

It is generally accepted that fractures should be treated by closed methods, however for certain femoral fractures in adults, closed methods yields an unacceptable high incidence of nounlon, malunion, delayed unlon, and disability. For these fractures various methods of open reduction and internal fixation have been recommended, but unfortunately, there are frequent reports of complications and failures. The recently developed association for study of Internal fixation (ASIF) compression plating apparatus, seems to satisfy the basic objectives of internal flxatlons: namely
