Comparative StudyInfluence of bone and soft-tissue operations on serum concentrations of growth hormone, somatomedin C and alkaline phosphatase.
After animal experiments suggested there was an interaction between growth hormone and bone healing, our aim in this paper was to ascertain whether there were any changes or possible interaction between the serum level of growth hormone, somatomedin C and alkaline phosphatase while a fractured bone was healing. To this end, the serum concentrations of growth hormone, somatomedin C, alkaline phosphatase and calcium were ascertained both pre- and post-operatively in two groups of patients--one with bone operations, the other with soft-tissue operations--and the results were compared. ⋯ An increase would have implied that these two hormones are directly involved in bone regeneration. There was no change in the serum level of alkaline phosphatase or calcium after either bone or soft-tissue operations.

Case ReportsTreatment of an old infection in a total hip replacement with an interim spacer prosthesis.
When treating a septic hip-joint prosthesis with bone loss of the proximal femur secondary to osteomyelitis, we implanted a specially designed prosthesis to act as a local antibiotic and spacer between the acetabulum and femur until the infection abated. Arthroplasty could then be carried out with no trouble and there was no recurrence of infection.

Case ReportsHemodialysis-associated amyloidosis of bone of beta-2 microglobulin origin.
A case of hemodialysis-associated amyloidosis in a patient who had been on hemodialysis for 10 years is described. Bone lesions were found in the humeral heads, carpal bones, and femoral heads and necks. ⋯ We reconfirmed that bone lesions associated with long-term hemodialysis are manifestations of amyloidosis of beta-2 microglobulin origin. Hemodialysis-associated amyloidosis should be considered in the treatment of long-term hemodialysis patients.

Case ReportsA case of hip osteoarthrosis contaminated by fungi. A histological study.
A pathological study of a surgical specimen of hip osteoarthrosis presenting a superficial fungal infection (presumably Aspergillus) without any known origin is reported. Fungal penetration was mild in cartilage and fibrocartilage and more pronounced in naked cancellous bone, but it did not occur in eburnated bone or in the deep osteomedullar area. This observation indicates an unusual combination of infection and osteoarthrosis. Relationships between fungi and bone or cartilage as well as interaction between osteoarthrotic remodeling and a superimposed disease are discussed.

Total decompression of the spinal cord for combined ossification of posterior longitudinal ligament and yellow ligament in the thoracic spine.
One of the causes of hyperostosis in the spinal canal, ossification of the posterior longitudinal ligament (OPLL) combined with ossification of the yellow ligament (OYL) in the thoracic spine, can result in serious myelopathy, leading to sandwich-type compression of the spinal cord from anterior and posterior. For such cases we devised a treatment of total decompression of the spinal cord and intervertebral body fusion. This operation consists of two steps. ⋯ This pre-treatment makes removal of the OPLL anteriorly during the second stage much easier, faster, and safer. This operation is lengthy and demanding. However, based on our experience so far, it appears to be a promising surgical procedure.
