The carpal scaphoid is the commonest of the carpal bones to be fractured, and this injury is the commonest to befall the wrist of working man. There is still some disaggrement as to the optimum treatment and as to how long immobilization should be maintained. The twenty seven cases of the carpal scaphoid were treated at department of orthopaedic surgery, Maryknoll Hospital. They were analyzed in regared to the clinical and radiological aspects. The results were summarized as follows. l. Of 27 cases 24 cases were in the age group 20 to 39, and all cases were male patients. 2. In 17 cases, the fracture was found in right side. 3. In 19 cases (70.4%), the fracture was found on the middle 1/3 of the carpal scaphoid and in 18 cases(66.8%), the fracture line was transverse. 4. The union rate of fracture was 100% in the distal 1/3 fracture, 89.5% in the middle 1/3 fracture and 66.3% in the proximal fracture. The average period of immobilization were 10.3, 14.9 and 15.3 weeks respectively. 5. By Maudsley's assessment, the end result was good in all cases of the distal 1/3 fracture, 84.2% in the middle 1/3 fracture and 66.7% in the proximal 1/3 fracture. 6. Traumatic arthritis developed in 3 cases, avascular ncerosis in 7 cases, nonunion in 4 cases.

BACKGROUND: Induced hypotension is effective in decreasing blood loss and providing better visibility in the surgical field. Extensive epidural block to T4 with intravenous infusion of low-dose epinephrine allows mean arterial pressure to 50 mmHg. We investigated the effects of hypotensive epidural anesthesia comparing with normotensive epidural anesthesia during total hip arthroplasty. METHODS: 40 patients scheduled for total hip arthroplasty under epidural anesthesia were randomly divided into two groups. In hypotensive group, 0.5% bupivacaine 20cc was injected into L1-2 epidural space and if sensory block reached to T4, then epinephrine 1~5 g/min was intravenously injected with continuous infusion pump. As a result, mean arterial pressure was maintained 50 mmHg, and heart rate, 55~80bpm. In normotensive group, 0.5% bupivacaine 20cc was injected into L4-5 epidural space, and sensory block reached to T8. Therefore blood pressure was maintained within 20% of preoperative baseline. RESULTS: There was apparent difference in blood loss between two groups (hypotensive group: 259 +/- 75 ml, normotensive group: 803 +/- 144*ml) (*:p<0.05). In addition, in the case of hypotensive epidral group, transfusion was not required and CVP, heart rate were not changed postoperatively. Cardiac, renal, and cerebral function were preserved too. CONCLUSIONS: Hypotensive epidural anesthesia with low dose of epinephrine infusion is safely lowering mean arterial pressure to 50 mmHg. This technique is associated with low blood loss, reduction in perioperative transfusion requirements, and has no side effects on CNS, liver, kidney and heart function.

The distal one-third fractures of tibia have much difficulty in treatment due to enumerous complications such as skin necrosis, angular deformity and delayed union. As for using Ender nails in distal tibial fractures, the stability of fixation can be strengthened with fanning of the nails in distal fragments and using more than 3 nails and 1cm longer nail. Twenty-two patients having distal tibial fractures, were carried out Ender nailing at Department of Orthopaedic Surgery, Maryknoll Hospital from May 1989 to September 1992. The results were as follows; 1. The distal end of fracture line was situated from 3cm to 9cm above plafond, and the mean duration of radiological bony union was 14.9 weeks except one case of nonunion. 2. Mild angulation developed in two cases and complications such as nonunion, superficial infection and backing out of nail were noted, but it did not affect the results.

In 1974, bipolar hip prosthesis was developed by Giliberty and Bateman to reduce the problems of unipolar prosthesis, including acetabular wear and acetabular protrusion, but the indications for it are still controversial. From July, 1988, to February, 1991, at Pusan maryknoll hospital, 37 hips in 33 patients of femoral neck fracture (25 hips) and avascular necrosis (12 hips) with relatively normal acetabular articular cartilage were treated with bipolar hip prosthetic replacement. The thirty-seven cases were reviewed for more than 3 years(range, 3 years to 4 years 8 months: average, 3 years 10 months), and assessed in terms of acetabular migration and function. The authors compared the datas of the femoral neck fracture with those of the avascular necrosis of femoral head. There was no statistical difference between two groups in function. But the acetabular migration of bipolar hip prosthesis used in femoral neck fracture was lesser than that of avascular necrosis of femoral head, and the serial acetabular migration disclosed gradual decrease. The authors concluded that the results of bipolar endoprosthesis used in femoral neck fracture was superior than those of avascular necrosis of femoral head with relatively normal acetabular articular cartilage.

We described 2 patients with Marchiafava-Bignami disease, a neurological disorder associated with chronic alcohol consumption. Patient 1 expressed general weakness and confusion, while patient 2 expressed dysphagia and seizures. Lesions involving the corpus callosum were identified with T2 weighted MR imaging in which there was a hyperintensity in the splenium of patient 1 and in the entire corpus callosum of patient 2. While the conditions of both patients were improved by with nutritional support, they were left with cognitive impairment.
