1.Duchenne Type Muscular Dystrophy: Report of 8 Cases
The Journal of the Korean Orthopaedic Association 1970;5(3):149-153
Clinical review has been made for 8 cases of Duchenne muscular dystrophy admitted to orthopedic Department during the time between 1964 and 1969. Duchenne type muscular dystrophy, (Duchenne, 1849), is the most common type of the progressive muscular dystrophy. A number of reports have been found regarding its symptomatology, pathogenesis based on muscle biopsy, heredity and the change of serum enzyme such as aldolase, creatine kinase, and transaminase, though no definite treatment has been known. The results were as follows: 1) All eight cases were male of 5 to 13 years of age. 2) Gowers sign and waddling gait were noted in all cases and contracture in two cases. 3) Familial occurrence was noted in two (Case 1, 2). 4) Urinary creatine value was elevated in all cases, while creatinine excretio decreased in seven cases.

The osteochondroma is a common benign tumor with osteocartilaginous exostosis. It may arise from any bone, but is observed most often on long tubular bones, particularly on their metaphyseal region. Osteochondroma may also arise from the rib but seldom grow to giant size. We experienced a rare case of giant osteochondroma arising from the left 5th rib. The patient, 41 years old man, had an adult fist sized mass on the left lower chest with mild aching pain on respiration. The large mass was examined by biopsy. It showed characteristic microscopic findings of osteochondroma. No evidence of malignant change was seen in this large tumor.

Congenital coxa vara is a rare congenital deformity, seen in infancy and childhood and the ratio of unilateral to bilateral is 3:1. The deformity does not become manifest until after birth and usually not until the age of walking. Pathologically, it consists of a progressively increasing acuteness of the neck-shaft angle;shortnees of the neck; a vertical direction of the epiphyseal plate; an oblique defect of the neck; a greater trochanter extending upward toward the ilium as a besk; a shortened femur; a secondary degenerative changese in the acetabulum due to malposition. We have experienced a case of bilateral congenital coxa vara treated with valgue osteotomy and the case review is presented.

The Journal of the Korean Orthopaedic Association 1971;6(1):79-82
Bilateral dislocation of the hip was observed in a 44-year-old man after the accident that he was overrun from backward by a slowly approaching goods-train. Successful manual reduction was obtained, followed by one month cast immobilization and partial weight bearing exercise thereafter. Peroneal palsy of right extremity, noted immediately after the dislocation, showed the prospect of good recovery. The mechanism of injury was also discussed.

PURPOSE: To evaluate the incidence of disc extrusion and neurologic deficit, the relation between disc extrusion and neurologic deficit and the treatment results according to our basic treatment principles in lower cervical facet joint fracture and dislocations MATERIALS AND METHODS: Twelve patients were evaluated, 8 male and 4 female with an average age of 41 years comprised the group. Six injuries were attributable to automobile accidents, 5 to fall from building, bed, floor and hill, and one to stand on her head. One case was distractive-flexion stage (DFS) 1, 9 cases with DFS 2 and 2 cases with DFS 3. Plain X-ray, CT, Myelo CT and MRI were used as a diagnostic tools. As a treatment criteria, feasibility of closed reduction, status of neuroglogic injury, and stability of injured spine were considered. Anterior cervical discectomy and fusion in accompanied disc extrusion, posterior reduction and fusion with triple wiring in unreduced dislocation, and anterior decompression and fusion in incomplete cord and root injury were selected as a basic treatment principles. RESULTS: Ten out of 12 cases (83%) showed neurologic deficits, 2 complete cord injury, 1 incomplete cord injury, and 7 radiculopathy. Nine out of 12 (75%) demonstrated disc extrusion and all disc extruded patients had neurologic deficits. Anterior cervical discectomy and fusion (ACDF) were performed in 5 cases, ACDF and posterior reduction with triple wiring (PRTW) in 4 cases, PRTW in 1 case, and skull traction and philadelphia brace in 2 cases. Seven radiculpathy patients were completely recovered and one incomplete cord injury patient can ambulate with spastic gait after surgery. There were 2 bed sore and 1 pneumonia in complications. CONCLUSION: Soft disc extrusion should be evaluated carefully with MRI and CT in lower cervical spine injury with the facet joint fracture-dislocations before the decision of treatment. As disc extrusion always accompanies neurologic deficit, it must be surgically treated by anterior cervical discectomy and fusion.

Treatment of open tibial shaft fracture is difficult, especially when there are severe soft tissue damage. Various complications are noted. The aims of treatment for the open fractures are to promote primary wound healing and union of the fractured bone. We have employed external skeletal fixation devices those are Hoffmann apparatus and pin & resin external fixator for the treatment of 34 cases of open tibial shaft fractures from March, 1981 to May, 1984. Each fixation method was divided into two type, one-plane bilateral frame (180' frame) and two-plane bilateral frame(120') Following results were obtained. 1. Open tibial shaft fracture was most commonly occured in age of high activity of male. 2. External fixation was very useful as a primary treatment method in open tibial shaft fracture. 3. The most common complication was pin tract infection. 4. Mean duration of fixation was 12.6 weeks. After removal of extemal fixation, 8 cases of delayed or nonunion were noted. In addition to bone graft, secondary open reduction and internal fixation with plate and screws (7 cases), only bone graft (1 case) were carried out. Good results were obtained. 5. There was no significant difference in bone union time between 180' frame and 120' frame. The complications were more frequently occured in 120' frame than in 180' frame.

Fractures of the proximal humerus occur more frequently in older patients but are seen in all ages and emerge epiphyseal separations. The objectives of treatment are restoration of all involved structures to normal anatomical state and a completely functional limb in the shortest time possible. One part and two part fractures were indicated in conservative treatment and surgical treatment in most of three, four part fractures. The results of treatment of forty four cases according to Neer's classification were analysed at the Department of Orthopedic Surgery, Chonbuk National University Hospital from Mar. 1978 to Dec.1985. The results were as follows. 1. The prevalent age distribution was third and fifth decade(48%) . 2. The most common cause of injury was slip down(14 cases, 32%). 3. The most frequent cases of the fractures in Neer's classification were two part fractures(22 cases, 50%). 4. Thirty one cases(71%) were treated by conservative treatment, twelve cases(27%) by open reduction and 1 case(2%) by prosthesis. 5. Good results were in 23 cases(52%) of one and two part fractures, fair in 17 cases(39%) and poor in 4 cases(9%) of two, three and four part fractures.

Diaphyseal fractures of the radius and ulna present high incidence of malunion and non-union because of difficulty in reduction and maintenance of two mobile, parallel bones in the presence of the pronating and supinating muscles which exert angulatory as well as rotational forces. Over the years various methods of open reduction and internal fixation or the closed method have been advocated, but open reduction, especially fixation with compression plate and screws resulted in more satisfactory results was proved recently by the major clinical reports. From March. 1977 to December. 1985, 59 cases of diaphysesl fractures of the forearm both bone in adult and children were managed in the Department of Orthopedic Surgery, Chonbuk National University Hospital and comparisions have been made between the conservative treatment group and operative group. The obtained results were as follows; 1. The most common csuse of injury was fallen on the outstretched hand in children and traffic accident in adult. 2. The most frequent site of the fracture was middle one-third(50.8%). 3. The most common pattern of the fracture was stable fracture(50.1%). 4. The applied methods for management of the fractures include cast immobilization after manual reduction or skeletal traction, K-wire fixation, compression plate and screws, intramedullary nailing, and combined. 5. Comparision of conservative treated group with operative treated group was as follows. 1) In roentgenologically, excluding those complicated by nonunion or infection, average bone union time of conservative group in children and adolescence was 10.2 weeks and in adult was 16.7 weeks, and of operative group was 13.9 weeks. 2) According to Grace and Eversmann's evaluation, Satisfactory results were shown in 80.0% of children and adolescence group treated by conservative method and 86.7% of adult group trested by compression plate and screws. 3) Among the various internal fixstion methods, compression plate and screws method was the best measure for rapid bone union and functional recovery in adult. 4) Any marked difference between each group was not seen in nonunion, but angulstory and rotational deformity were more common in conservative group and infection was developed 2 cases in operative group only. 6. There was no noticesble difference between each treatment in children and adolescence, but operative treatment, especially compression plate and screws, in adult was more superior to conservative treatment with. regard to bone union time and functional result.
