Injury of the hand has been steadily increasing in this country in recent years, accordingly the proper surgical care for recently injured hand can not be overemphasized. The author has experienced 25 cases of wringer injuries of the hand in the years 1965 to 1971, and the results of the treatment is reported in this paper. 1. 12 cases out of 25 were in age group between 16 to 20 year. 23 cases were male and two cases were female. The incidence was remarkably higher in male. 2. Mode of the injury; All the cases were injured on the joh in factory. 17 cases were injured by a roller machine with or without gears. Four cases were injured by a belt, and three cases were injured by a pressor. 3. Extent of the injury was classified in 10 groups. Avulsion of the skin below the palmar crease were six cases, and below the wrist were in other groups. 4. Fracture and traumatic amputation in the hands were complicated in 16 cases out of 25. 5. 20 cases out of 25 were treated with primary skin repair followed by debridement of the wound. Among them three cases obtained primary healing, and 17 cases had to be treated by repeating surgeries. Five cases out of 25 were treated with delayed primary skin graft, and four cases obtained primary healing. Accordingly the delayed primary skin graft had much better result than primary skin repair in this series. 6. 19 cases out of 25, had surgical amputation in the hands, among them 16 cases had complicated with fracture and traumatic amputation. The incidence of surgical amputation was higher on the proximal phalanx in 33 fingers out of 59 surgically amputated fingers. 7. 23 cases out of 25 were treated by skin graft. The result of primary healing in primary skin graft was three out of 12, and that of secondary skin graft was five out of six, and that of third skin graft was seven out of 10, and that of fourth skin graft was five out of seven, and that of fifth skin graft was one case. Accordingly, the result of primary healing was considerably higher in the group of the secondary skin graft. 18 cases out of 23 of skin graft were split thickness graft, four were full thickness graft and one was full thickness combined with split thickness skin graft. 8. Seven cases of contracture developed in the webs and joints after the healing of the skin graft were treated by web plasty and arthrodesis. One case had had surgical amputation of four fingers at the metacarpophalangeal joints was treated by resection of the second and third metacarpus, which made the hand possibIe to pinch and grasp.

Loss of radial nerve function in the hand results in a significant disability and so cannot extend the wrist, thumb & fingers according to the injury levels. Therefore the patient has great difficulty in grasping objects, especially power grip. Tendon transfers to restore function of extension of wrist and fingers are among the the best − most predictable transfers in the upper extremity. We performed 13 cases of tendon transfers for radial nerve palsy and extensive extensor ruptures from 1987 to 1993. The results were evaluated according to Arbitrary Value Method. Among 13 cases 30% of excellent, 46% of good, 24% of fair and no poor result were obtained and the better results were obtatined in low radial nerve lesion.

Supracondylar fractures of the humerus is the most common elbow fractures in children. The fractures so designated are in the supracondylar area of the humerus just proximal to the elbow, and do not directly involve the joint or the distal humeral epiphysis. Unfortunately, it can also be one of the most difficult fractures to treat. And the catastrophic picture of Volkmann's ischemic contracture and nerve injuries associated with these fractures, as after successful reduction, the late complications of loss of elbow motion, the chage in carrying angle, myositis ossifgicans, and delayed ulnar nerve palsy still lie ahead. For the period of 4 years and 10 months from May 1979 to March 1985, 47 patients who had been treated for supracondylar fractures of the humerus at the Department of Orthopaedic Surgery, college of medicine, Soon Chun Hyang University Hospital, are presented, The results obtained are as follows; 1. Supracondylar fractures of the humerus frequently occured between the ages of 4 and 9 years (70.2%) and the sex ratio was 2.1: 1 in male to female. 2. Of all fratures, 89.4% were the extension type and the left side was predominent in 55.3% than right. 3. According to the Holmberg clasification, Group 1 was 6 cases(12.8%), 10 cases(21.3%) in Group 2, 11 cases(23.4%) in Group 3, and 20 cases(42.5%) in Group 4. 4. Closed reduction with percutaneous pinning showed little changes in carrying angle. 5. Limitation of motion was most frequent complication after closed reduction with plaster cast immobilization. 6. By the modified Mitchell and Adams' criteria for grading results, excellent were obtained in 55.3 %, good in 44.7%, and zero in unsatisfactory. 7. In the neurovascular injuries associated with fractue, there were 4 neural injuries, and 2 vascular injuries. In 4 traumatic neuropathies, median nerve was involved most commonly and the were recovered spontaneously within 5 weeks. 8. Average time from injury to reduction was 1.6 day and delayed reduction or operation made worse the prognosis in most cases.

Vertebral pedicle screws have been widely used for secure posterior spinal fixation. When postoperative CT scan films were made, the blurring of pedicle screws were observed and we could not figure nut the exact diameter of screw and canal encroachment. There is no information in the difference hetween actual diameter and measured diameter of pedcile screws in CT yet. In this study, we try to find out partial voiume averaging artifact of pedicle screws made of stainless steel and titanium. Partial volume averaging artifact occurs when the shape of an object changes within the thickness of the CT slice or when a relatively small object is only partially included within the slice. Four pig cadaveric spinal column including 6 vertebrae each were prepared and CT scans were performed after insertion of C-D screws(stainless steel) to the left and TSRH screws(titanium) to the right pedicle. Another CT scans were performed after insertion of C-D screws to the right and TSRH screws to the left pedicle. The third CT scans were made after removal of all the pedicle screws. Actual C-D screw diameter was 6mm and CT scanned diameter was 8. I 6+/-0.66mm. Actual TSRH diameter was 6.5 mm and CT scanned diameter was 6.59+/-0.34mm. In conclusion, stainless steel has more partial volume averaging artifact than titanium. Safety margin of pedicle screw made of stainless steel is about 2mm and that of titanium is about 1 mm.

Injuries in the industries has been steadily increasing in this country in recent years. Injuries in the industries intricate in accoriance with the industrial environment, mechanism of injuries and the other factors of employees. In 6 years 201 patients with industrial injuries underwent treatment in the Department of Orthopaedic Surgery of the National Medical Center, and the result of treatment is reported in this paper. 1. 70 cases out of 201 cases were in the age group between 21 to 30 year. 186 cases were male and 15 were female. The incidence is remarkably higher in male. 2. In 80 cases the injuries were caused by machinery with pressor parts. The patients were chiefly manual workers in factories. 3. Of 280 injuries, 148 (62.8%) were upper extremities, 105 (37.5%) were lower extremities and 27 (96%) were trunks. The most common site of injuries was hand. 4 Of 146 injuries with fractures, 94 were treated by manual reduction and cast, and 52 were treated by open reduction. 5. Treatment for open wounds was debridement followed by delayed primary closure and/or skin graft. The primarily closed open wounds by local clinics were observed and treated according to wound condition. 6, 17 cases out of 22 phalangeal bone fractures were treated by manual reduction and splint. 5 cases were treated by K-wire internal fixation, among them 3 cases had to be treated by amputation. 7. Incidence of early camplication was considerably high with 137 sites out of 280 sites and the late complication was 79 sites after treatment of the early complications.

Subtrochanteric fracture of the femur is more difficult to treat than other bone fracture. Subtrochanteric fracture occurs in bone that is predominently cortical and biomechanical analyeis of stress in the femur ahowed that there is a high concentration of stress in the subtrochanteric region. These two factors, involvement of cortical bone tissue and concentration of stress, frequently have been mentioned as reasons for the high incidence of complications in the treatment of these fractures. The authors treated 23 cases of subtrochanteric fracture of the femur in 1974 through 1981, at the Department of Orthopaedic Surgery, School of Medicine, Soon Chun Hyang College. The results were as follows: 1. Of 23 cases of subtrochanteric fracture, 15 cases occurred in man, 8 cases in woman. 2. The most common cause of fracture was due to traffic accident. 3. Of 23 cases of subtrochanteric fracture, 9 cases were type lI, and 7 cases were type I & II by Fielding's classification. 4. 19 cases out of 23 were treated by means of the open reduction and internal fixation. As the internal fixation material, we used Kuntscher nail, Smith-Peterson and Thornton plate, Compression hip screw and plate until December 1978, and Zickel nail from January 1979. 5. The mean duration of bony union in subtrochanteric fracture treated by Zickel nail was shorter than the other implants. The incidence of complications such as coxa vara, delayed union, metal breakage occurred higher in the cases treated by Kuntscher nail, Smith-Peterson nail and Thornton plate, Campression hip screw and plate. 6. Zickel nail is one of the good implant for the treatment of subtrochanteric fracture of the femur.

Fractures in the subtrochanteric region of the femur present more formidable problems in treatment than do other trochanteric fractures, because such severe stresses exit at the fracture site. Therefore, as a rule we prefer to treat subtrochanteric fractures by operative means if possible. Many internal fixation devices have been recommanded for use in subtrochanteric fractures and each of these devices have advantages in certain types of subtrochanteric fractures, and their selection should be based on the individual fracture anatomy. A total of 20 patients with fracture of the subtrochanteric region of the femur, who were treated by internal fixation with Judet plate between January 1982 and December 1988 have been reviewed. Our conclusions were as follows; 1. Average age was 38 years old and most common cause of injury was traffic accident. 2. Cast immobilization was done after Judet plate fixation. Partial weight bearing ambulation was enabled from POD 10 weeks and full weight bearing ambulation was enabled from POD 16 weeks. 3. 18 in 20 cases, primary bony union was happened and the mean duration of radiological bony union was 24 weeks. 4. 3 cases of complications, metal failure with refracture (2 cases) and screw loosening (1 case), were occured due to early weight bearing in the post operative course. 5. Judet plate fixation was gave satisfactory result in uncomminuted subtrochanteric fracture, especially Seinsheimer's type I, II-A,B,C or Fieldings type I, II. 6. From a consideration of these series, Judet plate showed easy to use, perfect adaptation and rigid fixation. We thought Judet plate is one of a good implants for rigid fixation of subtrochanteric fracture without severe medial cortical disruption.

STUDY DESIGN: Surgically treated thirty-five Denis type B thoracolumbar and lumbar burst fractures were assessed to compare the differences of fracture patterns by the level of fracture. OBJECTIVE: To know the major surgical indications according to the level of fracture. SUMMARY OF BACKGROUND DATA: General operative indications of thoracolumbar and lumbar burst fractures were collapse of anterior body height more than 40-50%, kyphotic deformity more than 30 degrees, canal encroachment more than 50% and neurologic deficit. But we could not apply the same surgical indications to the whole thoraco]embar and lumbar burst fractures because their fracture patterns are different. METHODS: We compared the collapse of anterior body height, collapse of posterior body height, Cobb angle, wedge angle, canal encroachment and incidence of posterior injury according to the level of fracture. RESULTS: The higher the level of fracture, the more the collapse of anterior body height, Cobb angle, wedge angle and incidence of posterior injury But the lower the level of fracture, the more the canal encroachment. CONCLUSIONS: These results mean that the primary surgical indications for thoracolumbar junction are collapse of anterior body height, possibility of posterior injury and increased kyphosis, while for the lower lumbar fractures, amount of canal encroachment is an important factor to make decision for surgery.
