Treatment of the olecranon fractures by prolonged immobilization often results in limited elbow motion. With the use of tension band wiring, anatomical reduction was obtainable, and only a short period of immobilization was needed. We reviewed the cases of 17 patients who underwent surgical treatment of the olecranon fracture. All patients were treated by tension band wiring. In the overall series, we were able to obtain 53 percent excellent, 30 percent good, and 18 percent fair results.

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.

Femur neck fracture is well known as one of the major death cause after trauma in elderly patients, and unsolved fracture due to its frequent association with complications such as avascular necrosis and nonunion. Through meticulous evaluation of the patient, hip and surgeon's experiences, reduction of mortality and morbidity as well as rapid recovery of the patient to the preinjury social and ambulatory status without local complications and revision after treatment is urgently needed. Many factors about this fracture in itself were noted, but we have analyzed 18 femur neck fracture of the patients older than 50 years preliminarily according to age, fracture pattern, osteoporosis, etiology and method of treatment with its delay in association with major complications especially avascular necrosis and nonunion. The results are as follows; 1. Of these 18 fractures, 11 were in females, 8 were caused by minor trauma such as slipdown accident and 4 were associated with definite osteoporosis according to the Sing's classification. 2. Fracture pattern of these 18 are undisplaced in 4, displaced subcapital in 11, displaced transcervical in 3. 11 fractures in the patients older than 60 year are composed of 3 undisplaced or impacted fractures and 8 displaced subcapital fractures. 3. These 18 fractures were treated by closed reduction and internal fixation with multiple pins in 13, and hemiarthroplasty in 4, but one was not treated to die after discharge from hospital. 4. Undisplaced or impacted fractures and 3 displaced transcervical fractures were not associated with any complications such as avascular necrosis or nonunion. But 4 of 6 displaced subcapital fractures were complicated by avascular necrosis, 3 of which were reduced in the varus position within 1 week, and the other was reduced in the good position on 1 week after trauma. There was no complication in 2 displaced subcapital fractures reduced in valgus position within 3 days after trauma. According to the above results, the prognosis of the femur neck fracture is dependent upon the fracture pattern and delay in its treatment. So it is inevitable to reduce the fracture in anatomical or valgus position as early as possible. But the arthroplasty may be needed in displaced subcapital fractures delayed for several days, with its reluction in extreme varus position or impossible and with preexisting disease in the same hip joint (total hip replacement).

Subacute osteomylitis is far less common than acute osteomyelitis, characterized by insidious onset of the symptoms of mild local pain or discomfort without any acute systemic illness. Radiographic findings are not infrequently confused with benign or malignant bone tumors. From Jan, 1983 to Dec. 1991, we experienced twelve patients with subacute osteomylitis of long bones. Our clinical observations were as follows. 1. There were 11 boys and one girl with an average age of 9.7 years(range, 30months-16years). 2. The involved sites were proximal in 1, distal radius in 3, midshaft of femur in 3, distal femur in 2, proximal tibia in 1, and distal tibia in 2 cases. 3. All patients had insidious onset of mild to moderate pain. ESR was increased in 9 cases(75%) with a mean value of 44 mm/hr, but leukocytosis was not found. 4. According to the Green and Edwards' classification, there were type 1 in 1, type 2 in 3, type 3 in 3, and type 6 in 5 cases. 5. Eleven patients had operative treatment. The remaining one patient was treated by antibiotic treatment. 6. Primary treatment was successful in 11 patients who were followed for and average 9.5 months. One patients was lost to follow-up.

The author fractographically analyzed the cause of metal failure (the first time this procedure has been used for this metal failure) and also analyzed in clinically. In this study, I selected eight cases which have been analyzed fractographically. In all these cases, the analysis was done after treatment of metal failure of implants internally fixed to femur shaft fractures at the Department of Orthopedic Surgery, Yeung-Nam University Hospital during the six year period from May 1983 to September 1989. 1. Metal failure occurred in five dynamic-compression plates, one Jewett nail, one screw in Rowe plate, and one interlocking nail. 2. The clinical cause of metal failure was deficiency of medial buttes in five cases, incorrect position of implant in one case, and incorrect selection of implant in two cases. 3. The time interval between internal fixation and metal failure was four months in one case, between five months to twelve months in six cases, three years in one case. 4. The fractographically analytical cause of metal failure was ; first, impact failure, one case, second, fatigue failure, six cases, machining mark (stress riser), four case type: low consistent cyclic fatigue failure irregular cyclic fatigue failure third, stress corrosion crack, one case. 5. 316 L Stainless Steel has good resistance to corrosion. However, when its peculiar surface film is destroyed by fretting, it shows pitting corrosion. This is, perhaps, the main cause of metal failure. 6. It is possible that mechanical injury occurred in implants during the manufacturing of implants or that making a screw hole in the main cause of metal failure.

We present at least a one-year follow up of the 19 patients(twenty-two hands) of a open release of carpal ligament and external neurolysis in surgery for carpal tunnel syndrome. The transverse carpal ligament is exposed through a three centimeter paJmar incision in line with the axis of the third finger, started at the mid-point of the distal wrist crease and then straightly advanced. We analysed clinical manifestations and the following results were obtained; The average follow-up period was 27 months (12 - 120months). 1. According to the patients satisfaction of results(Cseuz criteria), the large majority of patients(91%) obtained good results. In 9% of the case (two hands) symptoms were siightly improved followed the operation but pain, numbness and paresthesia remained troublesome. 2. The mean grip and pinch strength of the fifteen hands were 23.4kg and 5.97kg respectively. 3. Thirteen(87%) of the fifteen hands that had thenar atrophy regained normal muscle bulk. 4. Six(50%) of the twelve hands that had denervation findings such as fibrillation or sharp wave were disappeared. 5. Twenty(91%) of the twenty-two hands that had increased values for two-point discrimination had normal values at follow-up.

The intramedullary nailing is a good method of treatment in femur shaft fracture but it is not available in some fracture pattern or fracture level. And it is very difficult with conventional Kiintscher nailing to prevent torsional stress and fix rigidly in unstable fracture of the femur shaft. The unstable fracture by comminuted fracture or segmental fracture, nonunion and pathologic fracture needed the rigid fixation. Interlocking Kuntscher IM nailing can provide antitorsional stability, good axial alignment and prevent shortening of the fracture site, also allow early ambulation and joint exercise. We analysed 51 patients 52 cases of interlocking Kiintscher IM nailing from May 1981 to March 1988. The interlocking Kuntscher IM nailing prevents the rotational and axial roading. The interocking Kuntscher IM nailing has expanded its application in fracture pattern and fracture site. The interlocking IM nailing provides rigid fixation in severe comminuted fracture. segmental fracture, long spiral fracture, and other several unstable fractures and eliminates splinting or external supports, so it is possible doing early joint exercise. The interlocking Kuntscher IM nailing was also considered best internal fixation method in pathologic fracture or sever osteoporosis. The static interlocking for rigid fixation and the dynamic interlocking method for axial compression to fracture site during weight bearing can be adapted appropriately to fracture pattern. Radiation hazard during the interlocking nailing is not considerable.
