Case ReportsOssification of the yellow ligament causing thoracic cord compression.
Ossification of the yellow ligament (OYL) is not infrequent in the cervical and lumbar regions but is very rare in the thoracic spine, with no more than 40 cases reported in the literature. We describe a 50-year-old male with progressive paraparesis and sensory dysfunction, secondary to OYL at T10-T11, studied by computed tomography (CT) and magnetic resonance imaging (MRI). ⋯ This pathological entity can be well defined by CT and MRI, and surgery by decompressive laminectomy is advised for all cases. The OYL should be removed both posteriorly and laterally to the dural sac to obtain sufficient decompression of the spinal canal.

Case ReportsThe changes occurring after the Putti-Platt procedure using magnetic resonance imaging.
The purpose of this study is to evaluate the magnetic resonance imaging (MRI) following Putti-Platt procedure for recurrent anterior dislocation of the shoulder. Six shoulders of six patients who had received Putti-Platt procedure were evaluated by the MRI before and after operation. After the Putti-Platt procedure the subscapularis tendon was thickened and an increased signal area on T2-weighted images were observed in four patients. ⋯ The course of subscapularis muscle fiber before operation was described as a mild arc, but changed to a straight line after the procedure in five patients. The findings in this study suggest that the Putti-Platt procedure leads to a remarkable increase in strength of subscapularis tendon and an improvement of laxity of subscapularis muscle. In conclusion, there is a good possibility that this procedure will increase the stability of the glenohumeral joint and be a successful treatment for recurrent anterior dislocation of the shoulder.

Case ReportsDisseminated hydatid disease causing paraplegia and destruction of the hip.
A patient who had had been treated by surgery for spinal echinococcosis in a Mediterranean country emigrated to northern Europe. After surgery, the echinococcosis disseminated and he developed chronic lytic and sinus-draining hydatid disease of the left hip and neuromuscular weakness of the left lower extremity. Seventeen years after the spinal surgery, he was referred to our hip service for a possible total hip replacement (THR) after receiving adequate chemotherapy against echinococcosis for nearly 3 years. Because of the poor results reported by others, we decided against THR; two of the four previous patients described in the current literature who had THR died due to complications.

Case ReportsRotationplasty as a salvage procedure in revision of tumor endoprosthesis of the distal femur--a report of two cases.
We performed two rotationplasties (type A1 and A2) as salvage procedures in cases of custom-made endoprosthetic replacements of the distal femur and knee joint. The patients suffered from malignant bone and soft-tissue tumors of the knee, respectively. ⋯ The other patient, suffering from parossal osteosarcoma of the distal femur, developed a local recurrence following endoprosthetic reconstruction. The functional abilities following the operation of these two patients suggested that rotationplasty was a viable alternative to above-the-knee amputation in failed or severely complicated total arthroplasty of the knee with massive bone loss.

A patient suffering from severe hemophilia combined with a large pseudotumor of his left thigh is presented, and the case history discussed. The occurrence of this tumor in hemophilia is considered with respect to the clinical, radiological, and laboratory findings.
