In fifty-two knees with spontaneous osteonecrosis the diagnosis was based on a subchondral transradiancy in the weight-bearing surface of the medial femoral condyle. Strontium-85 scintimetry showed a unique pattern, indicating a lively repair reaction by localised high values. Thirteen of fifteen knees followed between two and twenty-three years developed osteoarthritis. The prognosis was based on the size of the transradiancy and the focality of the
1. Three cases of acute peptic ulceration are reported after cerebral fat embolism complicating skeletal injuries. In two instances death occurred after perforation of an ulcer, and in the third intestinal haemorrhage led to death. 2. Although intracranial
1. Eleven cases of tuberculosis of the pubis are described. 2. The disease is often of insidious onset, and symptoms vary from vague discomfort to incapacitating pain in the region of the symphysis and the groin. 3. Abscess formation is common and was present in nine of the eleven patients when they first attended. 4. The
We performed curettage and bone grafting of amyloid cysts of the femoral neck in five patients on long-term haemodialysis. All had had hip pain on weight-bearing. The duration of haemodialysis before the operation averaged 15 years and the average age of the patients was 53 years. All the large cystic
A method is described which produces an isolated Grade II injury in the medial collateral ligament of the sheep's knee. The untreated injury was followed in 32 animals for up to six weeks. Histology revealed progressive healing of the
Thirty-nine patients with neuralgic amyotrophy were reviewed. In addition to the clinical findings reported in the neurological literature, we commonly found pain throughout the upper limb, and diffuse involvement of the brachial plexus. Five patients had spinal accessory nerve
We examined the pathogenesis of Schmorl’s nodes, correlating the histological findings from 12 lumbar vertebrae with the corresponding conventional radiographs, tomographs, MR images and CT scans. The last revealed round, often multiple cystic
We report a case of multicentric massive osteolysis. A 52-year-old woman presented with a three-year history of progressive deformities of the hands. She had osteolytic
1. Two girls with non-familial osteogenesis imperfecta who subsequently developed osteosarcoma of the femur are described. One is of special interest in that there were multiple bone metastases. 2. It is suggested that the tumours arose spontaneously and were not related to the underlying bone disorder. 3. Because of the relative frequency of hyperplastic callus formation in osteogenesis imperfecta it is most important that adequate biopsy material of any suspicious
The modified Magnuson-Stack procedure of lateral and distal transfer of the insertion of the subscapularis muscle was used in 38 consecutive patients with recurrent anterior dislocation of the shoulder, all of whom have been followed-up for a minimum of three years. There was only one failure; the other 37 patients had an excellent or satisfactory result with an adequate range of movement. Bankart and Hill-Sachs
Tuberculosis (TB) remains endemic in many parts
of the developing world and is increasingly seen in the developed world
due to migration. A total of 1.3 million people die annually from
the disease. Spinal TB is the most common musculoskeletal manifestation,
affecting about 1 to 2% of all cases of TB. The coexistence of HIV,
which is endemic in some regions, adds to the burden and the complexity
of management. This review discusses the epidemiology, clinical presentation,
diagnosis, impact of HIV and both the medical and surgical options
in the management of spinal TB. Cite this article:
We describe a technique for slow, progressive, symmetrical distraction of the growth plate using a lightweight dynamic axial fixation system. Results are given for the elongation of 40 bony segments in children with limb-length discrepancies and 60 segments in children with achondroplasia or hypochondroplasia. Increases in limb length of up to 36% were obtained in non-achondroplastic and up to 64.5% in achondroplastic patients. There were no nerve or vascular
We present three cases of a previously undescribed condition characterised by unilateral tibia vara associated with an area of focal fibrocartilaginous dysplasia in the medial aspect of the proximal tibia. The three children affected were aged 9, 15 and 27 months respectively. Two required tibial osteotomy, but in one the deformity resolved without treatment. The pathogenesis of the focal
Five cases of syphilitic aortic aneurysm with erosion of the spinal column are reviewed. Four patients underwent operation. When erosion of the spine was mild or moderate, the aortic
The causes of persistent symptoms after meniscectomy have been assessed clinically, radiologically and arthroscopically in 174 knees. The commonest finding was early degenerative arthritis (chondromalacia) of the femoral condyle (40 per cent). Retained fragments of meniscus were less common than expected (13 per cent), and
1. The literature on hyperextension injuries of the spine is briefly reviewed. 2. Such injuries in the cervical spine can be subdivided into five groups based on the pathological anatomy, based on the experience of fifty-one patients in the Spinal Injuries Centre for Victoria over the past five years. 3. Extension injuries of the thoraco-lumbar spine are discussed. They are rare and have a poor prognosis. 4. The importance of treatment based on sound clinical and pathological knowledge is emphasised, particularly in order that stable and unstable
1. Congenital coxa vara and infantile coxa vara must be separated as distinct entities. 2. Infantile coxa vara is likely to be due to distal movement of the head fragment relative to the shaft and neck. This can result either from severe trauma in normal bone or from shearing stress on an abnormal femoral neck. 3. There is no justification for considering infantile coxa vara as congenital, developmental or due to interruption of ossification. The nature of the pathological
1. The importance of recognising osteochondral fractures of the femoral condyle in the adolescent knee joint is emphasised. 2. The mechanism of the formation of the fractures is discussed. Essentially, a powerful rotary and compressive force shears off cartilage and subchondral bone. The absence of lateral condylar
The effects on articular cartilage of continuous and intermittent excessive pressures have been studied in the knees of rabbits. Severe degenerative changes in the cartilage were observed; these resembled the typical
