Of 899 patients with sickle-cell disease, aged between 6 and 28 years, who attended clinics in the Guinea Savannah of Nigeria in 1982 and 1983, 29 had symptoms of avascular necrosis of the femoral head. This group was studied in detail. Twenty-eight patients had haemoglobin-SS electrophoretic patterns and one had haemoglobin-SC. The male to female ratio was 1 to 1.6, and most of the patients were aged between 6 and 15 years at the onset of hip symptoms. These symptoms correlated with the
The type II Monteggia (posterior) lesion is a rare injury which is sometimes associated with ulnohumeral instability. We have reviewed 23 of 28 patients with this injury. A clinical and
We made a retrospective study of 55 primary total hip arthroplasties in 53 patients with a history of previous acetabular fracture. The mean follow-up was 7.5 years and the average age at fracture was 48.7 years. The incidence of

We have reviewed 13 operations on 11 patients using curettage and polymethylmethacrylate cement for giant-cell tumour of bone (GCT) to assess the value of radiology in the early detection of recurrence. There were four recurrences, the most specific radiological sign on plain
1. Some physical properties of living and dead bone have been studied in rats; most of these are interrelated and ultimately depend upon the composition of the tissue. 2. Dead bone, remaining within the body, does not take up measurable amounts of mineral from the tissue fluid but retains its original physical properties of

A case of the Jansen type of metaphysial dysostosis, followed for fifteen years from childhood to the age of nineteen, is reported.
The purpose of this study was to describe the
radiological characteristics of a previously unreported finding: posterior
iliac offset at the sacroiliac joint and to assess its association
with pelvic instability as measured by initial displacement and
early implant loosening or failure.
A new dynamic classification of Paget's disease is proposed, incorporating both the

X-linked hypophosphataemic rickets (XLHR) is a disease of impaired bone mineralization characterized by hypophosphataemia caused by renal phosphate wasting. The main clinical manifestations of the disorder are O-shaped legs, X-shaped legs, delayed growth, and bone pain. XLHR is the most common inheritable form of rickets, with an incidence of 1/20 000 in humans. It accounts for approximately 80% of familial cases of hypophosphataemia and serves as the prototype of defective tubular phosphate (PO43+) transport, due to extra renal defects resulting in unregulated The genome DNA samples of all members in the pedigree were extracted from whole blood.

Thirteen patients, aged 7 to 45 years, have been treated for atypical forms of spinal tuberculosis at the Neurological Centres at Benghazi and Lahore. All presented with signs and symptoms of compression of the spinal cord or cauda equina, ranging from paraesthesiae and increasing weakness to paraplegia and loss of sphincter control. None of them showed visible or palpable spinal deformity nor the typical

The primary aim of this study was to establish the cost-effectiveness of the early fixation of displaced midshaft clavicle fractures. A cost analysis was conducted within a randomized controlled trial comparing conservative management (n = 92) Aims
Patients and Methods
We have investigated the effect of multisegmental spinal fusion on the long-term functional and radiological outcome in patients with scoliosis. We compared these patients both with those whose spine had not been fused, and with a control group. We studied 68 patients with idiopathic scoliosis (34 operative and 34 non-operative) who had been followed up for a minimum of five years after treatment. They were matched for age (mean 44 years) and Cobb angle (mean 54°) at follow-up. An age- and gender-matched control group of 34 subjects was also recruited. All participants completed a questionnaire to assess spinal function and to grade the severity of back pain using a numerical rating scale.
