A clinical study of traumatic amputation by railroad accidents was made an 124 patients with 154 amputee, who had been treated at Department of Orthopaedic Surgery, National Seoul Hospital, during the 4 years period from January 1976 to December 1979. The results of this study are as follows: 1. The ratio of male to female was 9 to 1. The 3rd decade of age group showed the hightest number of accident causalties, as much as 37.1%. 2. Causalties showes a maximum during the sprlng (37.1%) and a minimum during winter. 3. The most common injured sites of the amputee were B–K in 44 cases among 154 cases of the amputee. 4. Considering the number of the multiple amputee in 26 casee among 124 cases, frequently they developed in 2 sites with 22 cases, 3 sites with 4 cases. 5. The frequent fracture sites with combined amputation were 18 cases of the pelvic bone, 12 cases of femur in amputation of the lower extremity. 6. Our methods of treatment were debridement, debridement and primary skin closure, debridement with open amputation, circular amputation, closed amputation with skin graft, and closed amputation. 7. The major complications were phantom limb in 108 cases (70.1%), infection in 44 cases (28.6%). 8. The most frequent infectious agent was pseudomonas (16 cases).

Two patients with Kienbocks disease were treated with microvascular loop graft to obtain the neovascularization of the avascular lunate. After each follow-up of forty-six months and eleven months, their results were complete relief of pain, definite decrease of sclerotic change in the radiologic finding and restoration of normal range of motion. This procedure is considered as a good method to help for the treatment of the Kienbocks disease.

Incorporation of bromodeoxyuridine(BrdU) and expression of osteocalcin and transglutaminase C(TGase C) during fracture healing and distraction osteogenesis were investigated in the rat with immunohistochemical studies. Transverse osteotomy was made at the proximal tibia. Bilateral dynamic mini-fixator was applied to immobilize the fracture and also to lengthen the leg. Distraction was started, at the rate of 0.25 mm twice daily, from the 4th operative day and continued for 7 days. Animals were killed for immunohistochemical studies on the 1st, 3rd, 5th, 7th, 14th, 28th, 42nd, 56th, and 84th day after osteotomy or distraction. Longitudinal histologic sections of the healing bone were stained with monoclonal antibodies against BrdU, osteocalcin, and TGase C. Radiologically, complete fracture healing was achieved in 6 weeks after osteotomy, while neo-osteogenesis was successfully achieved in the distracted gap in 7 weeks after the completion of distraction, During active healing stage of the fracture and distraction osteogenesis, BrdU was mainly expressed in the perisoteal and endosteal osteoprogenitor cells while osteocalcin was expressed in the proliferating osteoprogenitor cells, osteoblast, osteocyte, osteoid matrix, and chondrocyte. The expression of BrdU and osteocalcin in the mesenchymal cells from the surrounding soft tissues around the osteotomy site was negligible. At the site of enchondral bone formation, TGase C was expressed in the cytomplasm of more centrally located and matured chondrocytes, while oseocalcin was mainly expressed in the cytoplasm of peripherally located chondrocyte. These findings may suggest that osteocalcin participates in early phase of enchondral bone formation, while TGase C in the late phase, suggesting the role of TGase C in matrix stabilization. At the site of intramern-branous bone formation, the expression of TGase C was weakly positive in both osteoprogenitor cell and osteoblast. The reason of the difference in the expression of TGase C between the enchondral bone formation and intrarnembranous bone formation should be further investigated. Fracture healing and distraction osteogenesis was predominantly induced by intramembranous ossification rather than enchondral ossification. Periosteal osteoprogenitor cells appeared to initiate and to lead bone formation after osteotomy and distraction. Active proliferation and differentiation of osteoprogenitor cell ocurred during entire periods of distraction. Also, active osteoid matrix formation and mineralization was started from the 5th day of distraction and continued thereafter for further 4 weeks after completion of the lengthening. These findings indicate that preservation of the periosteum is essential to achieve successful fracture healing and distraction osteogenesis.

Sternocostoclavicular hyperostosis is a benign ossifying diathetic disorder characterized by hyperostosis and soft tissue ossification of the clavicles, anterior portion of the first ribs, and manubrium, with variable hyperostosis or ankylosis in the spine and sacroiliac joints. A review of the literature and our own case describes the clinical findings and its characteristic features in RI, CT, and plain film.

We studied the results in forty-three knees in thirty patients-three male and twenty seven femalewho had rheumatoid arthritis, osteoarthritis, traumatic arthritis and osteonecrosis in the knee and were treated by total knee joint replacement. The average age of the patients was 56.7 years. The results were anaysed after follow-ups ranging from one year to three years and seven months, average being 23.6 months. The assessment was made upon the knee rating system of the Hospital for Special Surgery; the results were excellent in 29 knees, good in 12, fair in one and poor in one. The improvement of the flexion contractures was significant (postoperative average 1.7 degrees compared with preoperative average 20.1 degrees). The postoperative active flexion ranged from 70 degrees to 140 degrees (mean 110.2 degrees). One knee had a deep wound infection. The radiological loosening demonstrated in three cases, two of them had incomplete, nonprogressive radiolucent line, being less than one millimeter in width in the tibial component, one who had a deep infection showed three millimeters radiolucent line.

The utility of computed axial tomography(CAT) in the diagnosis of spinal disorders has been the subject of considerable interest since the introduction of CAT scanning. Computed tomographic guided needle biopsy of 12 consecutive patients with a variety of undermined spinal disorders resulted in a 100% yield of positive tissue diagnoses, without signlficant complications. The principal advantage of cat guidance is the continuous direct observation of the needle tip position in relation to the target volume. We think that the application of computed tomographic guided needle biopsy in the lesions of the spine is of great value, because it is the single most accurate method of obtaining diagnosis other than by open surgical biopsy.
