Fractures of the acetabulum are relatively uncommon. But if fractures of the acetubulum are not accurately evaluated, classified, and reduced anatomically, major sequalae and complications are frequently developed. Because of complicated anatomy, difficulty with surgical exposure, severe comminution, and major associated injuries, the treatment of displaced acetabular fractures between conservative and operative methods is still controversial. We reviewed thirty five cases of displaced acetabular fracture treated operaively from January 1984 to December 1991. The prevalent age was the fourth decade. There was twenty seven cases of associated injuries, twenty two dislocations of the hip. According to the Letournel's classification, the most common fracture type was posterior wall and both column type. The fracture was fixed internally with only screws in thirteen cases and with plate and screws in twenty two cases. Among thirty five patients, five patients were lost in the follow up and another five patients had followed up lesser than one year. The mean duration of follow-up afrer the operation was three years (range, one to eight years). Among twenty five patients who had followed up more than one year, the satisfactory results were achieved in nineteen patients (76%) and the poor results were achieved in three patients (8%). The complications were post-traumatic arthritis, avascular necrosis of femoral head, osteomyelitis in iliac bone, skin necrosis, and heterotopic ossification.

Myositis ossificans progressiva is a rare disease characterized by the formation of areas of calcification in the interstitial connective tissue of muscles, tendons, ligaments, fascia, and aponeuroses. There may be exacerbations and remissions of the disease, but the general course is an insidious loss of body motion, affecting especially the neck, spine and upper extremities and, rarely, the hips and lower extremities. It is commonly associated with various congenital anomalies. The cause is unknown and there is no known effective treatment. Myositis ossificans progressiva associated with brachydactyly of both great toes, in a 34 year old femaIe, is presented with a review of the literature. Chief complaints were ankylosis of the left knee and hip of 9 years duration. We performed biopsy of tubular bone which is placed antero-lateral side of the left knee.

Monteggia fracture-dislocation was described as a fracture of proximal third of the ulnar with a dislocation of radial head by G. Monteggia in 1814. Bado named Monteggia lesion as a fracture of ulnar at any level and a dislocation of radial head. The authors reviewed sixty-three patents of Monteggia fracture who were treated at department of orthopedic surgery, Yonsei university college of medicine from 1980. 1. to 1985. 12. We emphasis especially on cause of injury, classification, direction of radial head dislocation, level of ulnar fracture site, treatment and result. The results were as follows: 1. There were 22 children and 41 adults among 63 patients. 2. The male was affected more frequenty than female (49:14) . The ratio between male and female was 3. 5: l. 3. The most common cause of injury was falling down (54%) in children and car accident (51%) in adults. 4. According to Bado classification, type I was 68%, type II 11%, type III 18% and type IV 3%. 5. The partial posterior interosseous nerve injury was noticed in 12 cases and the superficial radial nerve injury was in 3 cases. The nerve injury was recovered spontaneously in all cases. Dislocation of radial head was as follows: Anterior dislocation was 38%, anterolateral 41%, lateral 8%, posterior 10% and posterolateral 3 % 7. Location of ulnar fracture site was as follows: Metaphysis was 22%, proximal 1/3 24%, junction of proximal 1/3 and middle 1/3 38%, middle 1/3 14% and distal 1/3 2%. 8. Closed reduction of radal head dislocation was done in 45 cases, open reduction in 10 cases and radial head excision in 6 cases. 9. Closed reduction of ulnar fracture was done in 26 cases and open reduction 35 cases. 10. We obtained 93% favorable results in children and 71% in adults. Not only the prognosis of ch ildren was better than adults but also the recovery time of children was shorter than adult's.

Lumbar ligimentum flava obtained from 21 patients of spinal stenosis and 10 patients who underwent surgery for vertebral fracture(control group) were studied with hematoxylin-eosin stain, Verhoff s elastic stain, and immunohistochemical stains for S-100 protein ad fibronectin. The chondroid metaplasia of ligamentum flavum found more frequently and widely in the group of spinal stenosis compared with control group. The elastic fibers were decreased in number and irregu- larly arranged at the bone attached area in the group of spinal stenosis. There was tendency to increase the amount of fibronectin in the stroma of the ligamentum flavum in the group of spinal stenosis. Above findings suggest that chondroid metaplasia and changes of the elastic fiber in the peripheral area of the ligamentum flavum are able to contribute the pathogenesis of spinal stenosis.

Computed tomographic (CT) scans of 46 jaundiced patients were studied to determine the value of CT in the diagnosis of biliary pathology. AII ofthe 12 cases of medical jaundice had positive CT correlation. Of the 34 cases of proven surgical jaundice, 97 .8% were correctly identified by CT. In detecting the level of obstruction, the cases were divided into four groups by anatomica l segments, according to the number of visualized low density ringlike structures produced by dilated bile duct. All of the correctly diagnosed surgical jaundice was 91.2%. The presence of stones or mass, the level of obstruction and the relative size and shape of visualized distal ring had proved to be the most important variables in etiological diagnosis of surgical jaundice. The results indicate that CT is useful and highly accurate in differenting between surgical (obstructive) jaundice and medical (non-obstructive) ajundice, and determining the level of obstruction and the etiology of surgical jaundice.

Calvarium protects the brain, the most important organ. The defect of calvarium results in not only deformity but also fatal injury from the trauma. The cranial bone defects result from 1) removal of bone flap for intracranial decompression or infection 2) fracture 3) excision of tumor 4) craniectomy for craniosynostosis. The goals of cranioplasty are to protect the brain from trauma and make the aesthetically acceptable contour. From 1990 to 1995, we experienced twelve cases of cranioplasty using autogenous bone graft; 5 cases with rib bone, 3 cases with iliac bone, 2 cases with calvarial bone, and 2 cases with rib and calvarial bones. The result was very excellent without any significant complications.
