Two cases of typical ochronotic arthropathy were reported.Case 1; A 70-year-old man had had a considerable pain in the large joints for about ten years and a gait disturbance for eighteen months. The dark pigementation was noticed in sclera and ear cartilage, and his urine turned dark when a strong alkali was added to it. The ragiological examination showed disc calcification and bamboo spine, characteristic sign of ochronotic arthropathy. And the shoulder, hip and knee joints showed marked osteoarthrosis, but not ankylosis.Case; A 71-year-old woman had low back pain and right caxalgia. The findings of sclera, ear cartilage and urine were the same as Case 1. The ragiological examination showed marked disc degeneration and calcification without vertebral fusion, and moderate osteoarthrosis in the right hip.
We report a rare case of Osteopoikilosis associated with ichthyosis vulgaris and Crohn's disease. A 26-year-old man who was told of an “abnormal” radiograph was referred to our department. A skeletal survey was performed which revealed multiple oval and round densities measuring 3-7mm in diameter. The lesions were bilaterally situated in the epiphysio-metaphyseal region. The bones involved were the long bones and the small bones of the hands, feet, and pelvis. The ribs, skull and vertebral column were not involved. 99mTc-methylen diphosphate bone scan was performed and found to be normal. We describe here a case with osteopoikilosis, Crohn's disease and ichthyosis vulgaris. The etiology of the conditions was unknown, but we subsequently turned our attention to a possible link among these three conditions. The combination of osteopoikilosis, ichthyosis vulgaris, and Crohn's disease is considered a syndrome which is possibly inherited.
A 66-year-old man with pseudoarthrosis of the tibia in von Recklinghausen's disease was treated with an intramedullary Huckstep nail. Adult onset pseudoarthrosis in this disease has been reported only rarely. This skeletal lesion is considered to be the result of mesodermal dysplasia and osteomalacia.
Magnetic resonance imaging (MRI) is advantage ous to the diagnostic findings of spinal lesions. Recently, the examination utilizing MRI are becoming in common use for the diagnostic procedure of spinal disorders. However, as this examination (MRI) has been developed rapidly since 1980, there have been many undissolved problems.We are applying MRI mainly for spinal cord lesion.We reported two cases of spinal cord lesion and spinal disorder whose diagnoses were rather confused by utilizing this procedure (MRI).
We report two cases of stress fracture of the ribs related to sports activities.The first case involved fracture of the first rib caused by repeated stress from Japanese styled archery (kyudou). This is the first time such a case has been reported.The second case, a typical stress fracture of the lower ribs and spinous process of the seventh cervical vertebra was caused by a golf swing.
Osteochondroma is the most frequent benign tumor of the bone. Its migration is well-known but its spontaneous disappearance is rarely reported.A three years and nine months follow-up study of an osteochondroma occurring in the left humerus of a one-year-old boy is reported.The broad-based lump was located on the anteromedial aspect of the left humerus at the proximal diaphysis. The diagnosis of solitary osteochondroma was made roentgenographycally. The lesion was followed with roentgenograms without treatment.Roentgenograms made three months later showed no apparent change in the lesion, but subsequent roentgenograms made fourteen and twenty-four months after the initial roentgenograms showed the gradual regression of the lesion. The final roentgenograms made three years and nine months after the initial roentgenograms showed the lesion to have completely disappeared without surgical intervention.Spontaneous resolution or regression of osteochondromas is rarely recorded, but it is suggested that it may be more frequent.
We reported idiopathic Fanconi syndrome, which occurred in a 54-year-old female. She felt right coxalgia in 1975 and could not walk. She was suspected as osteomalacia and treated by Vit. D. In August, 1978, she sustained right femoral neck fracture, and then suffered from bilateral tibial and ulnar fractures with pain. She was treated but could not be relieved from pain. In September, 1981, she visited our institute and was diagnosed as Fanconi syndrome.
We report two cases of stress fracture.Case 1; The patient was a 10-year-old boy who had swum or playedbaseb all three times a week. He felt a pain in the distal part of left thigh in October 1983. Radiological examination of femur showed periosteal reaction and cystic lesion and tomograph showed fracture line. We diagnosed it as stress fracture situated in the fibrous cortical defect.Case 2; The patient was a 9-year-old boy. He suddenly felt a pain in the right clavicula whilst running with Kendo bamboo sword in January 1983. Radiological examination of right claviclua showed linear radiolucency. Stress fracture was diagnosed.
We report a case of extensor pollicis longs tendon entrapment in a fracture of the distal radius. A 17-year-old man fell from his motorcycle suffering a Smith's fracture of the right radius. The patient was treated with surgical reduction and internal fixation. The management of severely displaced Smith's fracture requires that any patient with loss of thumb extension should be observed closely. If there is no improvement, surgical exploration should be necessary.
