1. Lateral radiographs of fifty-seven club feet and seventeen normal feet were taken in forced flexion and forced extension. On these, the arcs traversed by the talus, the sole and the calcaneus were measured, as was the talo-calcaneal angle. 2. It was found that the ankle in club feet usually contributed more than half of the total sagittal movement of the foot. 3. Occasional cases were encountered in which the ankle was so damaged that it contributed only half or less than half of this movement. In such cases wedge
Osteoarthritis of the wrist is a complication of a number of common traumatic conditions. Arthrodesis of the radiocarpal joint, proximal row carpectomy and
The DNA content of the tumour cells in 10 patients with primary renal cell carcinomas was analysed; from six of the patients skeletal metastases were also studied. Four patients had homogenously diploid primary tumours, with solitary metastases. Six patients had aneuploid primary tumours, three with solitary and three with multiple metastases. In two patients radical

The results of 140 total hip revision procedures for "non-septic" loosening, dislocation, and fracture of the femoral stem or shaft have been personally reviewed and rated by the Harris method. The minimum follow-up period was six months: thirty-three (24 per cent) showed excellent or good results, seventy-two (51 per cent) showed fair or poor results. Subsequent
1. One hundred cases of congenital elevation of the scapula are reviewed; thirty-four were treated by operation. 2. A method of grading of appearance is suggested to assist in selecting cases for operation. 3. In very mild cases operation does not confer worthwhile benefit. 4. Very severely affected patients cannot be made to look normal. 5. The appearance often deteriorates during a period of rapid growth of the neck, making continued observation and reassessment essential. 6. The primary aim of treatment is to improve appearance; improvement in function is uncertain. 7.
1. Bony spurs resulting from erosion of the scaphoid bone and trapezium in rheumatoid arthritis can pierce the floor of the carpal tunnel and cause attrition rupture of flexor tendons–most often the flexor pollicis longus tendon. 2. It is difficult to show these spurs on conventional radiographs, but using a special tomographic technique we have been able to explore the floor of the carpal tunnel in three planes. Using this technique we have been able to guard the flexor pollicis longus against attrition rupture by early
1. Pain in the elbow in javelin throwers is a common complaint. 2. The commonest type is caused by recurrent strain of the medial ligament. It develops in individuals who employ an incorrect throwing technique. The symptoms are cumulative, increasing with throwing and decreasing and resolving with rest. Treatment consists in improving the throwing technique. Local anaesthetic injected into the tender area produces complete but temporary relief. Hydrocortisone may produce partial or complete relief. 3. A second type of "javelin elbow" occurs in expert throwers and is the result of hyperextension of the elbow at the end of the throw, causing an injury to the tip of the olecranon. The symptoms are the result of a single throw or "mal-throw" and are completely disabling. They resolve with rest but tend to recur. If the tip of the olecranon is fractured
1. Fifteen patients with spina bifida occulta are described in whom the fifth lumbar spinous process was pressing on the fibrous membrane that closes the spina bifida, or on the bony stumps of the defective lamina. 2. That this is a cause of low back pain, with or without pain referred to the lower limbs, is supported by the findings at operation and the results of treatment. 3. Eleven patients were treated by operation; in each the spinous process of the fifth lumbar vertebra pressed against the spina bifida, either directly or through the vestigial remnant of the first sacral spinous process. 4. In eight cases the fibrous membrane was adherent to the dura mater; in one case the nerve roots were adherent. 5.
1. Chondromalacia, sometimes a precursor of osteoarthritis, is present in the articular cartilage of the patella of most people by the age of thirty; it causes symptoms in only a few, and it gives rise to osteoarthritis in fewer still. It may progress slowly or quickly but there is no clinical method of assessing the prognosis at an early stage. 2. The earliest change is swelling of the cartilage associated with a decrease in the chondroitin sulphuric acid content of the matrix. Later the cartilage fissures and flakes off to expose the bone, and there are reactive changes in the cartilage, bone and synovial membrane. The process is described and the etiology discussed. 3. The symptoms, signs and treatment are discussed. Operation, which has been performed only when there are disabling symptoms, may consist in removing part or the whole of the articular cartilage, or in
In 45 patients we assessed the functional results and complications for three different reconstructive procedures after resection of primary tumors of the proximal humerus. An osteoarticular allograft was used in 11, a clavicula pro humero operation in 15 and a tumour prosthesis in 19. The glenoid was resected with the proximal humerus in 25 patients. The axillary nerve was resected in 42 patients. The complication rate was lowest after reconstruction with a tumour prosthesis. The clavicula pro humero operation resulted in the most revisions. Cumulative survival rates for all the reconstructive procedures were similar. At follow-up at two years the functional results for the three reconstructive procedures were the same with a mean functional rating of 79% (Musculoskeletal Tumor Society).
We describe the clinical and radiological outcome of 100 consecutive total hip replacements in 86 patients using the JRI Furlong hydroxyapatite-coated femoral component. The follow-up was 100% at a mean of ten years (9.0 to 12.0). All 54 living patients (62 hips) were examined annually. Their mean Merle d’Aubigné score was 5.8/5.6/4.6. A total of 32 patients had died. Their notes at the last annual assessment recorded a similar outcome to that of the living patients. Radiographs showed no radiolucent lines around any femoral component and there were no signs of impending failure. One patient required
From the European Osteosarcoma Intergroup study 202 patients were assessed with respect to their surgical treatment. Although treated in three different centres the survival of the three groups was identical (57% at five years). Two of the centres had rates of limb salvage of 85% and 83%, respectively, while the third had a rate of 49%. The corresponding risks of local recurrence were 13.3%, 6.8% and 2.5%, with all local recurrences arising in limbs with attempted limb salvage. Local recurrence was closely related to the adequacy of the margins of
Major ruptures of the rotator cuff were repaired in 89 patients over a six-year period, using an approach through the split deltoid muscle and the bed of the excised outer centimetre of the clavicle. Review of these patients showed that poor results were associated with larger cuff defects, with more pre-operative steroid injections and with pre-operative weakness of the deltoid muscle. A randomised prospective study showed that repair followed by splinting in abduction gave no better results than repair followed by resting the arm at the side.
Ninety-seven patients suffering from painful arc syndrome of the shoulder were studied. Local anaesthetic and radiographic contrast investigations were carried out. One-third of the patients had lesions in the posterior part of the rotator cuff which resolved after injections of local anaesthetic and steroid. One-third had anterior lesions in the subscapularis tendon: almost all resolved under the same regime but two required division of the coraco-acromial ligament. The remaining third had lesions of the supraspinatus tendon, usually associated with degeneration of the acromio-clavicular joint: most of these failed to gain relief from the local anaesthetic and steroid. Twenty-two operations were performed either by a transcromial or by a deltoid splitting approach.
Two distinct lesions affect the articular cartilage of the patella. Surface degeneration occurs particularly on the odd facet; it is age dependent, often present in youth and it becomes more frequent with increasing age. It probably does not occasion patello-femoral pain in youth, but may predispose to degenerative arthritis in that joint in later years and is regarded as a consequence of habitual disuse. The term "basal degeneration" is used to describe a lesion in which there is a fasciculation of collagen in the middle and deep zones of cartilage without, at first, affecting the surface. It was found astride the ridge separating the medial from the odd facet in twenty-three adolescents who had complained of prolonged patello-femoral pain. They were treated by
The clinical, radiographic and pathological features are described of eight cases of a bone tumour which we propose to classify as "malignant osteoblastoma". It presents the characteristics of genuine osteoblastoma but of an aggressive pattern, with more abundant and often plump hyperchromatic nuclei, greater nuclear atypia, and numerous giant cells of osteoclastic type. This rare tumour is regarded as the malignant counterpart of osteoblastoma and appears to be only locally aggressive. It should be separated from conventional osteosarcoma not only because of its peculiar histological pattern, but also because of its different clinical and radiological features and better prognosis. Thus seven of the eight patients were alive and free of disease from one and a half to eleven years after the initial surgical treatment, which in only two cases included amputation.
