Myositis Ossificans Traumatica of The Lower Extremity / 대한정형외과학회잡지

Traumatic myosistis ossificans is a reactive lesion occurring in soft tissues and at times near bone and periosteum. Twenty-four cases of traumatic myositis ossificans of the lower extremity were analysed dinically and radiologically who were treated at the Department of Orthopedic Surgery, Capital Armed Forces and Dae Jun Armed Forces General Hospital during the 3 years period from January 1977 to December 1980. The results were as follows; 1. The causes of trauma consisted of 11 football, 5 falling & slipping, 3 traffic accidents, 2 running, 2 working & training and 1 stick injury. 2. The earliest noticeable x-ray change was found on the 19th day (Mean: 25th day), 3. Soft tissue injuries in all cases were grouped according to the severity of trauma as mild, moderate, and severe. Myosities ossificans occured only in moderately and severely injured cases. The mean size of the calcified mass in severe cases was 23.9cm2 and was larger than that of moderate cases, and more lengthy treatment was required in severe cases; it required 2 weeks more than that of moderate cases. 4. One-third of all cases sustained reinjury. The mean size of the calcified mass of these 1/3 cases was 44.4cm2 and was larger than that of the mean size of all cases and more lengthy treatment of these 1/3 cases was required in reinjuried cases; it required 1.8 weeks more than that of all cases. 5. In those patients presenting after 3 weeks from injury, the mean size of the calcified mass was 37.6cm2 and was larger than that of those patients presenting within 3 weeks. Mean duration of treatment was 13.1 weeks in those patients presenting after 3 weeks, and 10.2 weeks in those patients presenting within 3 weeks. This figure suggest that early treatment is preferable in minimizing the size of the ossifying mass and shortening the duration of treatment.

A Case of Os Subtibiale / 대한정형외과학회잡지

Os Subtibiale, inconstant bone over the tip of the medial malleolus, is the very unusual findings and extreme rarity of the condition. We experienced a case of Os subtibiale in a 24 year old man who complained pain and tenderness an the bilateral medial malleolar region. The patient was treated by excision with satisfactory result.

Fracture of the Humerus from Throwing Hand Grenades: 4 Case Report / 대한정형외과학회잡지

Fractures of the shaft of the humerus due to muscle violence esp. from throwing hand grenades are uncommon. Even so there are reports from many authors documenting such fractures from throwing a javerin, baseball, hand grenade and arm wrestling. Fractures of this type are usually spiral in nature; located between the middle and distal third of the humerus. We have treated four such cases during activities in which hand grenades were thrown. These fractures were sustained by military recruits in the Department of Orthopaedic Surgery, Capital Armed Forces General Hospital from Jan. 1980 Dec. 1980.

Stress Fractures in Pubic Bone: Report of 3 Cases / 대한정형외과학회잡지

The occurence of stress fracturea at sites such as the metatarsal, tibia, fibula, and femur in military trainee and certain other very physically active groups has been reported frequently, but literature regarding stress fractures of the inferior pubic ramus has been very sparse. Authors spresent 3cases of stress fracture which was found in inferior pubic ramus in the newly recruited soldier in training corps; 1 case unilaterally and 2 cases bilaterally.

Fatigue Fractures of Tibial and Fibular Shaft in Soldiers / 대한정형외과학회잡지

A fatigue or stress fractures is one in which there is no initial overt break in bone continuity. Rather, there is a gradual alteration in bone architecture as a result of repeated stress. The stresses are submaxmum and usually are the result of unaccustomed activity. If continued, they may eventually result in a complete fracture. Fatigue fractures have been described in almost every bone in the body, but they are more common in the bones of the lower extremities. Fatigue fractures are commonly seen in military personnel, especially at basic training center, and have been noted in athletes, ballet dancers, laborers, and even pregnant women. The following clinical results were shown by analysis of 57 cases of stress fractures experienced in the Department of Orthopaedic Surgery, Capital Armed Forces General Hospital from Jan. 1978 to Sep. 1979. 1. In 57 fatigue tractures in military recruits, 48 were in the tibial shaft and 9 were in the fibula. 2. The main cause of the fatigue fractures was running on hard roads, and the other causes were marching on hard surfaces, playing football, and long jumping. 3. The site of predilection in the tibia was the proximal one third of the shaft, occurring in 35 (72.9%) of the cases. In the fibula the junction of the upper and middle thirds was most frequently affected, occurring in 4 (44.4%) of the cases. 4. Most of the tibial and fibular fatigue fractures were grade I (40 cases among 57), showing periosteal reaction only on one or two cortices. 5. All soldiers were treated by immediate stoppage of physical activity, with no plaster immobilization or non weight bearing.

Supracondylar Fractures of the Femur / 대한정형외과학회잡지

Supracondylar Fractures of the femur are not as cammon as femoral neck or intertrochanteric fractures, but their treatment may be just as difficult. Few surgeons have had extensive experience with this complex fractures of uncommon frequency. Until a few years ago, conservative treatment was considered superior to internal fixation of supracondylar fractures of the femur in adults. However, the development of new fixation devices and techniques has, according to several investigations, improved the results of the treatment of these fractures. The following clinical results were shown by analysis of 27 cases of femoral supracondylar fractures experienced in the Department of Orthopedic Surgery, Capital Armed Forces General Hospital in the past 3 years from Jan. 1977 to Oec. 1979. 1. The most common cause of these fractures were traffic accidents. 2. Of 27 cases, 11 cases were treated by conservative method, 16 cases were treated by open reduction and internal fixation. 3. Anatomical reduction and rigid internal fixation led to 80% of good to excellent results whereas only 33.4% of good to excellent results were obtained in patients in whom the fixation was not absolutely rigid. 4. In the treatment of supracondylar fractures of the femur, anatomical reduction and rigid internal fixation (80% of good to excellent results) resulted in better functional recovery after union of fractures than conservative treatment (45.5%).

Clinical Study for Achilles Tendon Rupture / 대한정형외과학회잡지

Achilles tendon is the most powerful tendon of the body and increases efficiency in weight bearing and walking capability. Since pares' report about the rupture of the Achilles tendon many authors have reported various causes, diagnostic and therapeutic methods. Most of the authors emphasized the early diagnosis and treatment resulted in good prognosis. There are many methods for the diagnosis of the Achilles tendon, roentgeography, angiography, electromyography, histologic examination and Thompsons test. The causes of the rupture of the Achilles tendon are direct and indirect injury. The two methods of treatment are conservative management and surgical treatment. Whether the cause of the injury is direct or indirect, restoration of function after treatment must be emphasized and the proper method of treatment must be determined by the degree of injury. Clinical analysis was done on 15 cases of Achilles tendon rupture treated at Orthopedic Department of Capital Armed Forces General Hospital from Oct. 1973 to Oct. 1978 with the following results. 1. In sex distribution, there were 13 male cases and 2 female cases and the age range of 20 to 30 years old was the most frequent (67%). 2. There was no difference In frequency between the right and the left side. 3. Achilles tendon rupture was two times more frequent in indirect cause than direct cause, especially after falling from heights and exercises. 4. The most frequent site of rupture was 2–5 Cm. above the insertion of the tendon (80%). 5. By means of a cost immobilization, good result was obtained in fresh partial rupture of the tendon. 6. Good results were obtained by end-to-end suture in fresh cases and reconstructive surgery in old cases. 7. Most of the patients returned to their jobs about 6 months after the operation.

A Clinical Study of Ankle Injuries / 대한정형외과학회잡지

Ankle injuries include not only disruption of bony architecture of ankle joint but also significant ligamentous and soft tissue injuries as well. Since ligamentous injury frequently has more serious implication than fracture, it is important that be recognized and included in the plan of treatment. The goal of treatment of ankle fracture is the establishment of the normal ankle joint. To obtain the this goal, the fracture should be reduced as accurately as possible (by open or closed), the fracture fragment must be retained in position until healing is secure, ligamentous structure should be repaired when indicated, and joint motion should be restored. The following clinical results shown by analysls of 108 cases of ankle injuries experienced in the Department of Orthopaedic Surgery, Capital Armed Forces General Hospital, from Jan. 1977 to June 1979. 1. The main cause of the injuries was falling from a height and the other causes were direct violence, traffic accident, and injuries in order. 2. All but one of the fractures could be classified in the manner described by Lauge-Hansen and the type of supination-external rotation was most common type in this series. 3. Ninty-two (85.1%) patients were treated by open reduction and internal fixation of both malleoli and sixteen by closed method. 4. The average period of cast immobilization was 8 weeks after closed reduction and that of open reduction was 6 weeks. 5. The good clinical results were achieved in 95 petients and the better results were obtained in fracturers treated in operative interventions.

Solitary Bone Cyst of the Capitate: A Case Report / 대한정형외과학회잡지

Solitary bone cyst are usually found in the juxta-epiphyseal region of metaphysis of long bones of children. They are rarely seen in non-tubular bones. The following case describes what we believe to be a solitary cyst of the capitate. Cyst was treated by radical curettage and packing with autogenous iliac bone. The most recent evaluation 7 months after surgery showed no discomfort.
