Fractures of the patella are predominantly intra-articular fractures of a sesamoid bone. The options of treatment vary from closed treatment to total patellectomy, in the middle of the spectrum are osteosynthesis and partial patellectomy. In this series, we experienced 59 cases of patellar fractures from October 1974 to October 1983 at the Department of the Orthopedic Surgery, College of Medicine, Kyungpook National University. The results were as follows:1. Most fractures were encountered in man from twenties to forties. 2. The most common cause of fractures was traffic accident(34 cases, 59.7%), followed by slip down or falling down(15 cases, 26.3% ). 3. The most frequent configuration of fractures was the comminuted. 4. 36 cases were treated with osteosynthesis (32 cases), partial excision (1 case) or total excision (3 cases). Of the 32 cases treated with osteosynthesis, most were treated by modified tension band wiring (16 cases). And as compared with other fixation techniques, the best results were obtained by this method. 5. Modified tension band wire fixation has given accepatable results even in severely comminuted, displaced patellar fractures. Excision was sometimes unavoidable.

The usage of electromyography is customized in the diagnosis of the neuromuscular disorder and the determination of motor conduction velocity is important in the diagnosis of the peripheral nerve lesion and in the posing of the site and severity of nerve damage. Although the radial nerve is frequently involved in generalized neuropathy and in entrapment syndrome, relatively fewer reports have appeared in the literature regarding the radial nerve. The purpose of this study is to determine the normal data of the motor conduction velocity of the proximal and distal segments of the radial nerve. The radial nerve fibers supplying the extensor indicis muscls muscle was stimulated at Erb's point, above the elbow and in the distal forearm and its muscle action potential was sampled. Seventy-four radial nerve were studied in thirty-seven healthy young subjects. The results obtained were as follows; 1. The mean proximal velocity was 70.7±6.8m/sec and the mean distal velocity was 57.6±4.3m/sec. 2. In any case tested, the proximal velcity was over 55m/sec. 3. The proximal velocity was faster than the distal velocity and the mean difference was 13.1m/sec In only 7 of the 74 nerves tested, the proximal velocity was slower than the distal velocity and the difference of Sm/sec was the most reversal. 4. The velocity in dominant limb was faster than that in nondominant limb. 5. There were no significant difference between the sexes.

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.

Accidents are the leading cause of childhood mortality and rank second only to acute infections as the cause of morbidity. The hospital morbidity and long term sequelae of injuries in children have greater medical and social significance than in adults. In order to determine what role the skeletal injuries play in morbidity and residual impairment in the severely injured children, We studied 75 consecutive surviving children who had multiple injuries, including a major fracture of at least one extremity or of the pelvic girdle. The severity of injuries was classified according to the Modified Injury Severity Scale (MISS) and compared severity of injuries with residual impariment. The results were obtained as follows. 1. Of 75 injured children, boys were 47 and 33 of the children were 6 to 10 years old. 2. Cause of injury of 66 children was motor-Vehicle related accident. 3. Most frequently combined injury with muosulosgkeletal injury was neural injury. 4. There were 133 fractures in 75 children and femoral fracture was most frequent. 5. The mean score on the MISS of 75 children was 21. Fifty-three ehildren had a score of 25 points or less. 6. Twenty-eight children had residual impairment, and their mean on the MISS was 25. 7. Most of the musculoskeletal impairment were attributable to the nature of initial injury.

An association study with Korean alcoholic patients(n=50) and normal controls(n=53) was performed to find the relationship between catechol-O-methyltransferase(COMT) gene polymorphism and alcoholism using polymerase chain reaction-restriction fragment length polymorphism. When we compared the allele and genotype frequencies of Nla III COMT gene polymorphism in alcoholism and normal controls, there was no significant difference between two groups. Our results do not support an association between the Nla III polymorphism of COMT gene and alcoholism.
