Between 1980 and 1984 nine adult patients in the renal unit of Guy's Hospital developed bone and joint infection. The commonest site of infection was the

In our practice sequestration of the shafts of long bones in children because of acute osteomyelitis continues to be a problem. Conventional procedures for bone grafting are likely to fail. Vascularised grafts with microvascular anastomosis are technically demanding with a high rate of failure. Transfer of the rib on its vascular pedicle to achieve anterior fusion in the thoracic
To validate the precision of digitally reconstructed radiograph (DRR) radiostereometric analysis (RSA) and the model-based method (MBM) RSA with respect to benchmark marker-based (MM) RSA for evaluation of kinematics in the native hip joint. Seven human cadaveric hemipelves were CT scanned and bone models were segmented. Tantalum beads were placed in the pelvis and proximal femoral bone. RSA recordings of the hips were performed during flexion, adduction and internal rotation. Stereoradiographic recordings were all analyzed with DRR, MBM and MM. Migration results for the MBM and DRR with respect to MM were compared. Precision was assessed as systematic bias (mean difference) and random variation (Pitman’s test for equal variance).Objectives
Methods
We describe a method of internal fixation for occipito-cervical fusion utilising a standard "small fragment" T-plate bent and fixed to the skull with three screws. The lower end of the plate is screwed and wired firmly to the

1 . The incidence of hydatid disease in bone is discussed and the relevant literature reviewed. 2. The parasitology and methods of control are described. 3. The pathology of hydatid disease affecting bone is described. 4. An analysis of fifty-three cases is made showing that the disease commonly occurs in the
Four children are described, each with spontaneous osteonecrosis affecting nearly one-third of the lateral femoral condyle. All the children had a motor and a sensory deficit in the affected limb: two had been previously treated for neuroblastoma of the
1. Epiphysial tilt commonly precedes slipping. 2. This tilt is due to a diminished or arrested growth from compression of the back of the epiphysial plate. 3. The stresses on the upper end of the femur are such that the upper femoral epiphysial plate is peculiarly liable to compression. 4. A primary abnormality of the cartilage of the epiphysial plate renders it susceptible to the effect of compression. 5. Because this abnormality is diffuse, deformities due to a similar pathology may be found elsewhere, notably in the
Hydatid disease of bone is rare. It probably represents between 0.5% and 4% of all human shydatid disease and, in about 60% of patients, affects the
We have reviewed, retrospectively, 66 adult patients who were treated for lumbar or lumbosacral tuberculosis. A total of 45 had a paravertebral or epidural abscess, 24 had clinical instability and 18 presented with a radiculopathy, of which six also had a motor deficit. The diagnosis was usually made on clinical and radiological grounds and they were followed up until there were clinical and radiological signs of full recovery. Conservative treatment with antituberculous drugs was successful in 55 patients (83%). None had persistent instability, radiculopathy or neurological compromise. We feel that tuberculous spondylodiscitis, especially in the lumbar
