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.
