Failure of fixation of intertrochanteric fractures that have been treated with a fixed-angle sliding hip-screw device is frequently related to the position of the lag screw in the femoral head. The purpose of this study is to introduce the concept of the tip-apex distance and to demonstrate its clinical usefulness as a predictor of cutout of the screw used for fixation of the intertrochanteric fractures of the hip. The tip-apex distance is the sum of the distance from the tip of the lag screw to the apex of femoral head on an anteroposterior radiograph and this distance on a lateral radiograph after controlling for magnification. To determine the value of tip-apex distance in the prediction of cutout of the lag screw, 67 intertrochanteric fractures that have been treated with a fixed-angle sliding hip screw device were studied. The minimum duration of follow-up was three months during which period all of the fractures either healed or had failure of the fixation. The average tip-apex distance was 21mm (range,22.8-65.8mm) for the successfully treated fractures compared with 35mm (range,8.4-65.8mm) for those in which the screw cutout. There was strong statistical relationship between an increasing tip-apex distance and the rate of cutout. An unstable fracture, a poor reduction were also associated with a significantly increased risk of failure due to cutout.

The tibia is the most commonly fractured bone of all the long bones. In this age of vehicular accidents, the tibia is frequently subjected to high energy trauma. Anatomically the tibia has poor soft tissue coverage and poor blood supply. Therefore severe injury on the tibia can lead to severe complication and major disability. 41 adult patients with comminuted fracture of the tibial shaft were treated by OR/IF with D.C.P. and bone graft at the Department of Orthopedic Surgery, Kyungpook University Hospital from January 1978 to June 1986. These were analysed according to mechanism of injury, degree of comminution, timing of operation, soft tissue injury and operation time. Bone union and end results of treatment were reviewed. The results were as follows Of 41 cases, causes of injury were vehicular accident in 32 cases. 34 cases had associated injury on other part of body and average injury per case was 1.7 injuries. Based on the classification of Johner and Wruhs, the B group with butterfly fragment was 27 cases and C group was 14 cases. Among the B group, B2 was most common as 14 cases. Average union time was 18 weeks and delayed union and nonunion were 6 cases. Degree of comminution of fracture might be important fractor to bone union. According to the end result of Johner and Wruhs, excellent and good were 31, fair and poor were 10. Of the 41 cases, 10 cases had permanent disability. 4 cases had angular and rotational deformity alone and 1 case had shortening of tibia more than 1 cm, 1 case had both of them. Limited R.O.M. of ankle joint (>50%) occured in 4 cases. The post-operative infection occured in 6 cases, 3 were superficial infection but 3 cases were osteomyelitis. OR/IF with D.C.P. on comminuted tibial shaft fracture was a risk operation. Therefore proper method of treatment should be selected according to degree of comminution, timing of operation, presence or abscence of open wound and associated injury.

Soft tissue defect on dorsum of hand requires immediate soft tissue cover to achieve early wound closure and to minimize wound infection and scarring. If the tendon or bone was exposed and the deep structures were absent, flap was required to provide adequate protection and allow proper function of the underlying structures. Small size in skin loss can easily be covered with local flaps but major defects involving the dorsal aspect of the hand should be coverd with distant flaps, free flaps or radial forearm flaps. Techniques in distant flaps require staged procedures and free flap transfer to obtain soft tissue cover in a single stage require microsurgical techniques. The reverse radial forearm flap is a fasciocutaneous flap based on the radial artery which together with its two venae comitantes lies invested in a condensation of the deep fascia known as the lateral intermuscular septum. The authors had treated 5 cases of distally based reverse forearm flap for soft tissue reconstruction on 2 patients of crushing injury with soft tissue defect on hand, a patient with Marjolin's ulcer on dorsum of hand due to previous burn scar and a patient with soft tissue necrosis on dorsum of both hands due to extravasation of adriamycin during chemotherapy. It has proved to be one of the saftest, simple and effective one-stage method of soft tissue reconstruction in hand without long term immobilization. The results of these operation in cover of soft tissue defect have been satisfactory.

A young metastatic lung cancer patient developed empyema due to an infection with carbapenem-resistant Acinetobacter baumannii. Hydropneumothorax was detected and managed by a tube thoracotomy. However, persistent air leakage through the chest tube was observed due to the presence of a bronchopleural fistula (BPF). As hypercapnic respiratory failure had progressed and the large air leak did not diminish by conservative management, a pumpless extracorporeal lung assist (pECLA) device was inserted. The pECLA allowed the patient to be weaned from mechanical ventilation and the BPF to heal. The present case shows the effective application of pECLA in a patient with empyema complicated with BPF and severe hypercapnic respiratory failure. pECLA enabled us to minimize airway pressure to aid in the closure of the BPF in the mechanically ventilated patient.

Torsades de pointes is characterized by paroxysms of ventricular tachycardia at rates typically greater than 200 beats/min in which QRS morphology shows alternating polarity in an undulating pattern so that the complexes appear to be twisting about the beseline;this arrhythmia is virtually always associated with prolongation of the QT interval. Its importance lies not in its unusual structure but in the potentially fatal outcome if conventional treatment is administred. Torsades de pointes was diagnosed in 4 patients;the first with hypokalemia, the second with congenital QT prolongation syndrome, the third with amiodarone, the fourth with organophosphorous and hypokalemia. Treatment of these patients consisted of potassium supply, isoproterenol, lidocaine, phenobarbital, tenormin, phenytoin, cardioversion, atropine. Three patients improved successfully, but one patient died, as a direct result of the ensuing ventricular fibrillation and cardiac arrest on one hour after admission.

The subject of ankle injuries has for a long time been embedded in controversy. The injuries to the ankle joint complex include not only injuries that cause disruption of the bone architecture of the ankle joint but often significant ligamentous and soft tissue components. Strong differences of opinion exist regarding the preferred method of treatment, the length of time immobilization is necessary, the postreduction management and the criteria of what constitutes an acceptable reduction. Follow up of 52 cases was possible which were admitted to the department of orthopedics, Kyung- pook University Hospital during the period of January, 1974 to december 1983. The results obtained from this study were as follows; 1. Among the 51 patient, male was 45 (88.2%) patients and female 6 (11.8%) patients. Most of the patient were in the ages between 20 and 30. 2. Of the 52 cases, the main cause of fractures were traffic accident 33 (63.5%) cases and the other causes were falling from a height 9 (17.5%), slipping down 3 (5.7%) and sport injury 1 (1.9%) in order. 3. Open fracture was 16 (31%) and closed fracture was 36 (69%). 4. According to the classification of Lauge-Hansen, the supination-external rotation type 18 (34.6%) was the commonest type. 5. Among the 52 cases, 32 cases were treated by open reduction and 20 cases by closed reduction. 6. The average peried of the cast immobilization after the open reduction was 6Wks. but the closed reduction was 8Wks. 7. According to clinical and radiological accessment of the result of treatment for bimalleolar Fx, internal fixation of both medial & lateral malleolus was better than medial malleolus only. 8. The fibular fracture involving lateral malleolus and the diastasis of the distal tibiofibular syndesmosis were very important in ankle stability and were treated by internal fixation for accurate anatomical reduction.

Dislocation of the metacapophalangeal joint of the finger is apparently rare except thumb. The mecchanism of injury seems to be direct injury that produces hyperextension of metacapophalangeal joints. In 1957, Kaplan advocated the triple incision, that is release of the volar fibrocartilaginous plate, the natatory ligament, and the superficial transverse metacapal ligament, expose the operation field through palmar approach. In 1975. Becton advocate direct dorsal longitudinal incision. The advantages of this approach as compared with the volar approach are 1. There is full exposure of the fibrocartilaginous volar plate, the main structure blocking reduction. 2. Digital nerves are not as apt to be damaged. 3. Accurate reduction and fixation of the osteochondral fracture of the metacarpal head is possible. We exprenced 6 cases of index metacarpophalangeal dislocation and treated with dorsal approach.
