Fifteen patients with identical symptoms of pain and tenderness at the tip of the greater trochanter are reviewed. Diagnosis by the referring doctor was usually osteoarthritis of the hip or sciatica, but localised tenderness and pain on resisted abduction were the only clinical signs. Radiographs were usually normal. Most cases were relieved by one or more local steroid injections. This disorder has much in common with tennis elbow, golfer's elbow, coccydynia and policeman's heel. We suggest that all these conditions may be traction syndromes.
A review is presented of 13 young patients with congenital scoliosis who were treated by epiphysiodesis of part of the vertebral bodies combined with posterior fusion, both on the convex side; the plan was to arrest growth on the convexity which, combined with growth of the concave side, would result in progressive correction of the curve. The first patient was operated on at the age of four years and has now reached skeletal maturity with complete correction of her curve. Several others, still growing, are showing progressive correction. Only three curves, in which kyphosis was more severe than scoliosis, have deteriorated since operation. Although full assessment must await skeletal maturity of all the patients, this approach appears to have sufficient potential to justify an early report.
Thirty patients with mild idiopathic scoliosis were reviewed between 7 and 17 years after spinal maturity. These patients were not treated surgically because they were cosmetically acceptable, and unlikely to progress further. Standardised radiographs taken at spinal maturity and at review were comparable, so any change represented true progression in a fully mature spine. There was an increase of lateral curvature in 60 per cent of the patients; this was small and always under 10 degrees. No change was seen in rotation. Lateral curves over 30 degrees, with rotation of 25 degrees or more, were found to be almost twice as likely to progress. It is suggested that caution should be exercised in leaving these curves untreated, and follow-up into early adult life is advisable.
Two hundred and fifty cases of myelodysplasia were reviewed in relation to spinal deformity. Approximately half of the children had, or were expected to develop, curves severe enough to need operations and only 10 per cent maintained completely undeformed spines. The most frequent deformity was scoliosis which could be subdivided into congenital and developmental types. The latter was of mixed aetiology, neuromuscular imbalance and asymmetry of the neural arch both contributing, while in some cases no causative factors could be identified. The best early indicator that developmental scoliosis was likely to appear was a high segmental level of both the neurological deficit and the neural arch defect. Deformity was very unlikely to start after the age of nine years.
One hundred and three patients with scoliosis treated by posterior fusion and Harrington instrumentation are reviewed. The fusion technique described does not require added bone. Walking in a localiser plaster is encouraged as soon as the wound is healed, usually two weeks after operation. The results compare satisfactorily with others published. It is concluded that added bone is not necessary unless neural arch defects are present, and that early walking is advantageous and without risk to the correction.
1. The production of scoliosis in young animals by resection of the posterior ends of the ribs is described and the etiological mechanisms discussed. It is suggested that retardation of posterior rib growth, removal of mechanical support from one side of the spine, and disturbance of proprioceptive impulses are the factors which initiate the deformity. 2. Some or all of these mechanisms may contribute to the production of certain human curves, for instance impaired rib growth and support in post-poliomyelitic deformities, proprioceptive and reflex disturbances in syringomyelia. 3. Therapeutically resection of the heads and necks of the ribs on the concave side of thoracic idiopathic curves is followed by improvement in some cases. Exactly how much improvement, in what proportion of curves, and for how long it will be maintained cannot be defined at present, but therapeutically worthwhile effects have been obtained, especially in children under five years old; even if this improvement is followed by later progression, several years of freedom from bracing may have been achieved, and the operation has not in any way interfered with subsequent correction and posterior fusion if this has seemed necessary. It is thought that this operation may have a small but useful role in the early management of idiopathic scoliosis, especially in a young child who is not responding well to bracing.
1. Correction of hallux valgus by spike osteotomy of the neck of the first metatarsal is described, and the results in eighty-two feet are presented. 2. A high proportion of satisfactory results can be obtained, but great care is needed in both selection and technique. 3. The ideal case is one of moderate deformity, without degenerative arthritis, and with symptoms referable to increased width of the forefoot; the operation should not be performed in cases with obvious degenerative change, nor when metatarsalgia is a prominent symptom. 4. It is important to displace the metatarsal head as far laterally as possible, and vital to avoid dorsal angulation or displacement. 5. It is suggested that enough is now known about the natural evolution of hallux valgus and the results of some operations for prophylactic surgery to be undertaken in carefully selected cases.
1. Pathological hallux valgus may be differentiated from an increase in the normal valgus alignment of the great toe by the relationship to each other of the articular surfaces of the first metatarso-phalangeal joint; these are congruous in the normal joint, but displaced on each other in the pathological. 2. The earliest change is lateral deviation of the proximal phalanx on the metatarsal head, which may progress rapidly to subluxation. 3. Subluxation is an early change in a high proportion of cases, and is frequently present when the patient is first seen in adolescence. 4. Once subluxation has occurred progression of the deformity is likely. 5. Metatarsus primus varus and hallux valgus increase 6. It is suggested that hallux valgus should be regarded primarily and fundamentally as a subluxation, or tendency to subluxation, of the first metatarso-phalangeal joint.
