ジャーナル フリーIntracortical chondroma is very rare. In a comprehensive review of English literature, only two previous reports of the intracortical chondroma were found. We reported a case of intracortical chondroma at the second metacarpal. The patient was a 21-year-old man. On the first visit to our clinic, a hard mass was palpable at the ulnar and dorsal aspect of the left second metacarpal, and he had pain on extention and ulnar deviation of his left index. On the radiogram, a translucent lesion surrounded by the cortical bone was found at the ulnar aspect of the second metacarpal. Pathological diagnosis was intracortical chondroma, because the chondroma was entirely surrounded by the cortical bone. En bloc resection and iliac bone graft were performed. No recurrence has been found for six months after surgery.抄録全体を表示PDF形式でダウンロード (3572K) -

ジャーナル フリーCase 1: A 63-year-old man complained of left inguinal pain. He was diagnosed as having a left femoral aneurysm and artificial vascular grafting was performed. Operative findings and pathological diagnosis revealed vascular leiomyosarcoma. The tumor recurred and five simple resections were performed. One year after the primary operation, the patient was referred to us and a hemipelvectomy was performed. He received postoperative chemotherapy, however, local recurrence was seen after 6 months and he died from the disease 1 year after surgery. Case 2: A 35-year-old woman complained of stiffness in the right thigh. Operative findings revealed the tumor invading femoral vessels, and the pathological diagnosis was vascular leiomyosarcoma. After preoperative chemotherapy, a wide resection and reconstruction of the femoral artery and vein were performed. One year after surgery, she was alive with pulmonary metastasis. Case 3: A 51-year-old man complained of stiffness in the right knee and a simple resection was performed at another hospital. He was referred to us and a wide resection was performed after preoperative chemotherapy. Operative and pathological findings indicated subcutaneous leiomyosarcoma. After the operation, postoperative chemotherapy was performed. Neither local recurrence nor metastasis had occured for 6 years. In all three cases, pathological findings were specific to leiomyosarcoma, that is, spindle cells with acidphilic cytoplasma positively stained with α-SMA and desmin.抄録全体を表示PDF形式でダウンロード (6632K) -

ジャーナル フリーWe examined 26 cases with suspected tumor mass with ultrasonography between 1998 to 2000. Seventeen cases were diagnosed. Diagnosis was 8 ganglion, 3 lipoma, 3 atheroma, 3 Baker's cysts, and 1 malignant fibrous histiocytoma. Ultrasonography is readily available, inexpensive, and noninvasive. Generally ultrasonography assists in determining the size and consistency of a soft tissue mass. It is apparently useful for the diagnosis of the lipoma, atheroma, and ganglion.抄録全体を表示PDF形式でダウンロード (4348K) -

ジャーナル フリーA 38-year-old male was admitted to our hospital complaining of a huge mass on his thigh. CT scan and MRI revealed an enlarging intramuscular tumor in his quadratus femolis muscle suggestive of malignancy. The exact diagnosis was not available with open biopsy. As we coould not rule out the suspicion of malignant tumor, resection was performed, consisting as a partial (2/3) resection and curettage of most contents. Histological examination of the resected mass showed an organized hematoma surrounded by dense fibrotic tissue, eosinophilic material, capillary vessels and many inflammatory cells especially histiocyte. The mass was diagnosed as chronic expanding hematoma as a result. The mechanism of chronic expanding hematoma is unclear. In our review of literature, only 10 cases including this one located in the extremities could be found. About two years later, the mass has reduced and the patient activity of ADL improved significantly.抄録全体を表示PDF形式でダウンロード (4314K) -

ジャーナル フリーA 17-year-old female patient with voluntary anterior deslocation of the shoulder is reported on. There was no history of significant trauma, no generalized joint laxity, no signs of neurological or psychological problems. She could voluntarily dislocate her left shoulder to anterior-inferior by the action of the pectoralis major muscle. Diagnostic imagings including X-ray, double contrast arthrogram, arthro-cT and MRI showed enlargement of the capsule without Bankart or Hill-Sacks lesion. After ruling out the possibility of psychological problems, we performed an operative stabilization by arthroscopic anterior capsular plication and cutting pectoralis major muscle at the insertion of the humerus. At 2-year follow-up of the patients reported no recurrence, good shoulder function, and no disability at work. This results confirms the unsuspicious psychological evaluation and our therap eutic management.抄録全体を表示PDF形式でダウンロード (2572K) -

ジャーナル フリーTwelve patients were treated with modified Bristow procedure for recurrent dislocation of the shoulder in 1997 to 1999. Seven patients were male and five were female. The mean age was 25 years (range; 16 to 40), and the mean follow-up period was 12 months (range; 4 to 23). Only one patient had dislocation of the shoulder again after operation. The mean JOA score was 95 points, but the mean JOA score of four patients which had inferior instability with anterior instability was 87 points.
The capsular shift procedure is apparently necessary in addition to the modified Bristow procedure for these patients.抄録全体を表示PDF形式でダウンロード (3430K) -

ジャーナル フリーThe Purpose of this paper is to evaluate an arthroscopic examination on posterior superior glenoid impingement in 11 cases of throwing athletes. Under arthroscopy, with the arm placed in external rotation and 90° abduction, impingement was found between the posterosuperior border of the glenoid and the undersurface of the cuff (arthroscopic internal impingement test).
This test supports the belief that internal impingement occurs in overhead throwing athletes.抄録全体を表示PDF形式でダウンロード (2453K) -

ジャーナル フリーA pathohysiological study of frozen shoulders was carried out by assessing thermography and deep body thermometry results together with the patients' subjective and objective symptoms. Active and dummy magnets were randomly assigned to patients (18 males and 20 females) in a double-blind study. All patients were magnets for three weeks, and subjective and objective symptoms were observed to be improved significantly 1 week after the application of the active magnets. The skin and deep body temperatures in the painful portion significantly increased with exposure to the active magnets at 2 weeks and 3 weeks after the application.
These findings suggest that the static magnetic fields might gradually increase blood circulation.抄録全体を表示PDF形式でダウンロード (270K) -

ジャーナル フリーWe report a case of femoral neck pathological fracture due to amyloid bone cyst. The patient was a 45-year-old female who had been undergoing hemodialysis for 24 years, who developed large amyloid bone cysts of the femoral neck and acetabulum. She visited our hospital after experiencing hip pain while riding a bus.
She was diagnosed with a femoral neck pathological fracture and treated with non-cemented prosthetic replacement of the femoral neck, curettage and bone grafting of the acetabulum cyst. Pathological study of the tissue revealed amyloid deposits. Diagnosis of femoral neck fractures due to amyolid bone cyst, should be considered when examining patients under going long-term hemodyalisis with hip pain.抄録全体を表示PDF形式でダウンロード (2866K) -

ジャーナル フリーA forty-five-year-old female who had been on hemodialysis for twenty six years developed extensive bone cyst in the femoral head. The cystic lesion showed low-signal intensity on T1-weighted images of magnetic resonance imaging. On T2-weighted images, it showed iso-signal intensity. She experienced hip pain and the cystic area in the plain radiograph covered 37.5% of the femoral head using the lateral head index. We therefore performed hip arthroplasty with bipolar endoprosthesis. At operation, we found a change in the color of the articular cartilage, synovium proliferation and granulation tissue in the joint space. Histological examination using dylon staining showed amiloid deposition in the cartilage, synovial membrane, granulation tissue and bone specimens. In addition, the existance of many inflammatory cells in the synovial membrane and some giant cells like osteoclast contacting with the bone trabecular around amiloid was demonstrated pathologically.抄録全体を表示PDF形式でダウンロード (6207K) -

ジャーナル フリーA case of adult onset hypophosphatemic osteomalacia in a 53-year-old man was reported. The patient was referred to our hospital for evaluation of proximal muscle weakness at the age of 36, and diagnosed as hypophosphatemic osteomalacia based on histological findings of calcaneal bone biopsy. Large doses of 1 α (OH) D3 up to 24μg/day with or without oral phosphate (1g/day) were ineffecive, so that his gait disturbance worsened progressively and he could not walk without a cane at the time of admission. Plain radiograph revealed Looser zone in the right femur. Bone mineral density of the lumbar spine was decreasing at a rate of 4.2% per year. Laboratory tests showed hypophosphatemia (1.4mg/dl), low tubular reabsorption of phosphate, and high serum alkaline phosphatase. Treatment with high-dose oral phosphate (4g/day) and 1 α (OH) D3 (3μg/day) was instituted. Therapy was accompanied by a rise in the serum phosphate level, and dramatic symptomatical and radiological improvements, although the patient had hypocalcemia, hyperthyroidism, hypokalemia, and frequent diarrhea attributed to the inorganic phosphate. Careful follow-up is necessary to minimize these hazards of treatment with high-dose phosphate.抄録全体を表示PDF形式でダウンロード (1728K) -

ジャーナル フリーHowever, there are few reports of cubital tunmel syndrome in hemodialysis patients. Carpal tunnel syndrome is frequently seen in patients undergoing long-term hemodialysis. We experienced four cases of cubital tunnel syndrome in hemodialysis, all of whom had a history of hemodialysis for over 10 years. Recently, it has been reported that the number of the occurences of cubital tunnel syndrome has increased due to the overuse of the elbow joint in work and sports. Two patients had overused of their elbows at the work before the introduction of hemodialysis and had no amyloidosis deposits as demonstrated by histopathological findings. Thus we suspected that hemodialysis had not been the only factor in the occurrence of cubital tunnel syndrome. In two patients with amyloidosis, the numbness worsened after hemodialysis. We believe that the true cause of cubital tunnel syndrome in these patients would be amyloidosis deposits due to hemodialysis.抄録全体を表示PDF形式でダウンロード (3549K) -

ジャーナル フリーStiffness index of the calcaneous and the BMD (bone mineral density) of the distal radius (1/10, 1/3) and lumbar spine (L2 to 4) were measured in the 20 patients with osteoarthritis of the knee by using an ultrasound bone densitometer and DXA (dual X-ray absorptiometry) respectively. The average age was 72.9 (55 to 73). The patients consisted of 15 females and 5 males. The percent average of the age-adjusted stiffness index of the calcaneous and BMD of the 1/10, 1/3 radius and lumbar spine were 83.5%, 111.5%, 106.7%, and 99.4% (P<0.01: calcaneous vs 1/10, 1/3 radius, P<0.05: calcaneous vs lumbar spine, lumbar spine vs 1/10 radius). There was a relatively low correlation between the calcaneous and radius, lumbar spine compared with that of the radius and lumbar spine. Osteoarthritis of the knee influences the bone, especially in the calcaneous.抄録全体を表示PDF形式でダウンロード (321K) -

ジャーナル フリーWe present a 30-years-old male case of insufficiency fracture of the bilateral femoral neck. He suffered from bilateral femoral neck fracture without a definite trauma.
Radiological examination on the first visit showed a minute changes in both femoral necks, which were inferred fracture retrospectively. On the second visit, radiogram revealed obvious desplaced femoral neck fractures. The patient was therefore admitted into our hospital and fractures were fixed with cannulated screws. At admission, laboratory date revealed no definite abnormalities, except bone atrophy in bone mineral analysis. These findings suggested that idiopathic osteoporosis acts as one of the factors which caused the insufficiency fracture.抄録全体を表示PDF形式でダウンロード (3825K) -

ジャーナル フリーTransient osteoporosis is a clinical syndrome of unknown etiology characterized by the acute onset of pain gradually worsening over several weeks to months. The most commonly involved joint is the hip, followed by the knee, foot, and ankle. Radiographical changes occur, but laboratory studies are generally unremarkable. This report describes a case of transient osteoporosis of the knee.
A fifty year-old man suffered from left knee pain without any history of injury. Plain radiograph of the left knee revealed mild oeteopenia of the femoral medial condyle. MRI scan showed increased signal on T2 weighted images in the corresponding region. Routine laboratory tests were normal. Spontaneous remission was observed in the knee joint with protected weight-bearing after one month, and MRI became normal. The pain gradually subsided in 5 months. The clinical and imaging findings were consistent with the diagnosis of transient osteoporosis.
Transient osteoporosis has been defined as spontaneously occurring pain and osteopenia of the involved bone. The area symptoms of the affected sometimes misleading, careful follow-up is therefore required. In this case, MRI served as a useful method for the diagnosis and follow-up of transient osteoporosis.抄録全体を表示PDF形式でダウンロード (3934K)
