It was difficult for a baseball player to recover completely from a frontal dislocated shoulder or subluxation even though an operation was performed because it limits the range of motion of the shoulder. However, recently many baseball players wish for complete recovery. Our team has been making efforts to meet their wishes. This is a report of some cases we have treated. We define a complete recovery as a state when a player can throw a ball fast enough to play on a team without experiencing pain.

We experienced eight fractures of the coracoid process during the period from 1984 to 1992. Seven cases of them were basal fractures and one case was apical one. Two cases were isolated, being in the other six cases combined with acromioclavicular dislocation or clavicular fracture. One patient with minimally displaced fracture of the coracoid process was treated conservatively. But the others were treated by internal fixation with a cannulated malleolar screw, one of which was inserted percutaneously. Postoperatively, Kenny-Howard type harness was worn in each case for four weeks. The result was satisfactory and all surgical cases were united. Neither infection nor loss of function was observed. These fracutures were assessed regarding the cause of injury, region of contusion, and complicated osseous-articular injuries around the shoulder. From the mechanism of injury, they were classified into two major groups: Group I; direct fracture, group II; indirect fracture. The direct fractures were subdivided into two types: Type I; by force from outside, type II; by force from inside. The indirect fractures were further divided into two types; Type I; by ligamentous traction, type II; by muscular traction. It is recommended to treat operatively if a gap of indirect fracture is five millimeter or more on roentgenograms.

We compared the invasion of Gamma nails (GN) and Compression hip screws (CHS) in operations to determine blood loss.25 trochanteric fractures treated with GN, and 24 with CHS were available for prospective study. We exchange the amount of transfuse blood for the rate of change of hemoglobin content (Hb), and investigated the difference of it. Hb for GN was more reduced compared to Hb for CHS from time of operation to the next morning. But external blood loss for GN was less compared to CHS.We concluded that internal blood loss for GN was much higer than CHS, so the invasion of GN is not low in the point of blood loss.

We reported a case of ossification at the insertion of both Achilles tendons which is reportedly rare condition.The patient, forty-seven years old, suffered from severe pain at the insertion of bilateral Achilles tendons. He had no systemic, metabolic, or inflammatory disease and there was no history of trauma or surgery. He was successfully treated by excision of ossified mass in both Achilles tendons.In this case, the etiology of ossification may be secondary to minor trauma at the insertion of Achilles tendon. The ossified mass is usually asymptomatic and needs no treatment, but if it becomes painful, the excision of it should be considered. The recurrence of ossification is rare, but the careful course observation of this condition should be required.

Thirtyone patients on chronic hemodialysis developed carpal tunnel syndrome were reported. This syndrome was found in the side of the arterio-venus fistula in 24 hands and the opposite side in 20 hands. All patients complained paresthesia, dysesthesia, nocturnal pain in the hand.The duration of hemodialysis at the time of the operation was 12 years on an average, ranging from 7 years to 22 years. At surgery, the median nerve was found to be compressed under the thicked transverse carpal ligament in all cases.The histological examination of synovia and transverse carpal ligaments obtained at the time of operation revealed pale eosin stained fibrous degenerative material (H-E stain) among the fibrous connective tissue. Congo-red stain was positive. It's regarded as an amyloid material.Surgical decompression of the median nerve at the wrist resulted in the immediate relief of the symptom.

Osteonecrosis of the femoral head is usually progressive and once collapse of the femoral head develops, joint destruction almost invariably follows. Therefore, various methods of surgical treatment have been developed in an attempt to save the femoral head and maintain the natural function of the hip joint. We studied the histological findings of the necrotic lesion of cases of osteonecrosis of the femoral head following transtrochanteric anterior rotational osteotomy described by Sugioka and varus osteotomy. We were able to evaluate four hips followings osteotomy. They were all male with average age at operation being 36 years and with age range of 25-52 years. In two patients, osteonecrosis was associated with steroid administration and in he remaining two cases with alcohol abuse. According to the classification of the Japanese Investigation Committee, three hips were stage II and one was stage III. All four hips were obtained following removal of screws from 2 to 4 years postoperatively average of 2.9 years). The specimens were cut to thickness of 5μm and were subjected to hematoxylin and eosin stain and Pas-Alcian blue stain. Histologically, in three cases the preoperative necrotic lesion remained as necrosis without reparative reaction and in one case proliferation of new fibrous connective tissue and blood vessels was observed in the necrotic lesion. Though the number of osteoblasts and osteocytes was decreased, the bone structure was well preserved, indicating that the purpose of femoral osteotomy was achieved. It is necessary in future to study cases with a longer postoperative course by delaying the time of bone biopsy.

This study was conducted to verify the clinical outcomes after treatment of fracture of the hamate hook in baseball players. Nine male baseball players, who underwent resection of the hamate hook with a J-shaped skin incision from the ulnar midlateral area of the palm to the palmar side of the wrist, were included in this study. In one patient, palmaris longus tenden grafting was added because of a partial tear of the flexor digitorum profundus of the little finger. The mean patient age at the time of surgery was 19.2 years (range: 14 to 56 years), and the mean follow-up period was 3.6 months (range: 1 to 7 months). Except for the one patient with tendon grafting, eight patients made a full return to baseball in mean about 5.3 weeks. As a postoperative complication, there was numbness of the ulnar nerve area in one patient for only a short period. None of the patients had any pain in the treated hand at the time of the final examination. In cases of hamate hook fracture in baseball players, excision of the hook is useful for early return to the sport.

In the present study we report two cases of secondary chondrosarcoma arising from osteochondroma. The first case was a 54-year-old male who had a large mass in the right pelvis, which arose from multiple osteochondroma. The second case was a 34-year-old male who had a cartilaginous mass arising from solitary osteochondroma of distal fibula. Radiological examination showed irregular calcification and thick caltilaginous cap in both cases. The secondary chondrosarcoma arising from solitary osteochodroma such as in the second case, is extremely rare. There has been only one previous report of a case in which secondary chondrosarcoma arose at distal fibula. In the present two cases, we resected the two tumors by wide margin. The clinical course of these patients was good and they returned to their jobs.

19 patients with intramuscular hemangioma (IMH) in the extremity have been treated at our institution over the last 15 years. The average age was 20 years (range, 1 to 70 years).Involved sites were the lower extremity in 12 patients, and the upper extremity in 7. The mean follow-up period was 5.1 years (range, 0.5 to 15 years). Longstanding pain and swelling were common symptoms. Plain X-ray showed phlebolith in 10 patients. Magnetic resonance imaging, 13 patients, delineated the extent of the lesions, and revealed characteristic structures within the tumors. These two imaging modalities were informative for diagnosis and surgical treatment planning. Angiography and compued tomography were less valuable, although they also showed the lesions to some extent. Diagnosis of IMH was obtained preoperatively in 8 patients, however, the remaining 11 patients needed open biopsy. Extirpation of the tumors was performed in 17 patients, one of whom also received radiotherapy. Of the remaining two patients, one receieved only radiotherapy. The other, tumor was left untreated, because it was too extensive to be excised without significant morbidity. These two patients, had no major disability at the latest follow-up. Local recurrence occurred in 2 of the 17 surgically-treated patients. Complete extripation is needed for local control of the disease, but feasibility of the surgery depends on the tumor's location and size. Low dose radiotherapy may be a useful alternative, when the lesion is extensive, and the symptoms warrants.

We have experienced three cases of cervical cord or radicular symptoms caused by acupuncture needle migrating into the cervical spinal canal.Two patients had cevical cord symptoms and the other one had radicular symptoms. The first case was a 63-year-old female, who noted numbness in her bilateral fingers, 5 years following her acupuncture treatment. The second case was a 52-year-old male, who had had a nuchal discomfort and treated himself with a needle. He unfortunately broke the needle. Two months following the event, numbness appeared in his bilateral upper and lower extremities. The last case was a 44-year-old male. He had felt radiating pain in the middle of his acupuncture treatment. He subsequently developed pain in the great occipital nerve area during neck rotation.The needles were removed surgically, in all cases. The symptoms were dramatically resolved in the second and the third cases, In the first case, however, the neurological deficits did not improve after the operation, which seemed to be ascribable to the irreversible changes which had occured in the spinal cord.

We compared our cases with a nationwide epidemiological survey of spinal cord injuries in Japan from January 1990 to December 1992. We had 16 cases of cervical spine injury due to diving accidents which constituted 3% of all injuries and 54% of sports injuries. The average age of them was 24.1 years, ranging from 12 to 41 years. The nationwide epidemological survey included 114 cases of diving accidents which constituted 1% of all injuries and 22% of sports injuries. The average age of them was 22.1 years, ranging from 10 to 55 years.Since the greater part of both cases had severe clinical symptom, it was difficult to recover from the palsy and return to social life. And so we think that a wide educational program is essential in order to reduce the number of diving accidents.

Abstract We report two cases of osteochondritis dissecans (OCD) in identical twin male badminton players. The younger brother presented at the age of 15 years complaining of a two-year history of right knee pain during sports activity. Physical examination showed a positive result in the patella grinding test, but no range of motion limitation. Plain radiography showed that the lateral femoral groove had irregularity and a radiolucent region, and a diagnosis of OCD was made on the basis of magnetic resonance imaging (MRI). Arthroscopy demonstrated softening of the OCD lesion and partial cracking of the cartilage. The OCD lesion was fixed using bone strips. Five months after surgery, MRI demonstrated almost total disappearance of the lesion, and the patient returned to his original sports activity. The elder brother presented at the age of 16 years with a three-month history of left knee pain during sports. Physical examination revealed only mild tenderness of the patellofemoral joint. Plain radiography and MRI showed OCD in the lateral femoral groove, and arthroscopy demonstrated the lesion but no cracking of the cartilage. As had been the case for the younger brother, surgery was performed using bone strips. Because the lesion appeared to show good remodeling into normal bone on MRI at three months after surgery, the patient returned to his original level of sport. Although familial incidence of OCD is not unusual, cases in identical twins are very rare. The similarities of both site and onset timing of these OCD lesions suggest that some genetic factor may contribute to the cause of OCD other than overloading due to repetitive and strong sports activity. Also, our clinical results indicate that fixation with bone strips is a useful therapeutic option for OCD in the femoral groove to facilitate a prompt return to sports activity.
