Scoliosis seen in the chicken after pinealectomy resembles adolescent idiopathic scoliosis in man. It has been suggested that in both species, deficiency of the pineal hormone, melatonin, is responsible for this phenomenon. In nine patients with adolescent idiopathic scoliosis and in ten age- and gender-matched controls, the circadian levels of serum melatonin and the excretion of urinary 6-hydroxy-melatonin-sulphate, the principal metabolite of melatonin, were determined. There were no statistically significant differences in the secretion of serum melatonin or the excretion of urinary 6-hydroxy-melatonin-sulphate between the patients and the control group. The hypothesis of melatonin deficiency as a causative factor in the
We have studied the histological appearances of forty femoral heads with idiopathic avascular necrosis. The characteristic histopathological changes of recurrent necrosis were present in 83 per cent. Recurrent necrosis occurred widely after revascularisation had progressed as far as the subchondral zone. The
Recent total knee arthroplasty (TKA) designs have featured more anatomical morphologies and shorter tibial keels. However, several reports have raised concerns about the impact of these modifications on implant longevity. The aim of this study was to report the early performance of a modern, cemented TKA design. All patients who received a primary, cemented TKA between 2012 and 2017 with a minimum two-year follow-up were included. The implant investigated features an asymmetrical tibial baseplate and shortened keel. Patient demographic details, Knee Society Scores (KSS), component alignment, and the presence of radiolucent lines at final follow-up were recorded. Kaplan-Meier analyses were performed to estimate survivorship.Aims

1. Eleven patients with juvenile rheumatoid arthritis, most of them young adults at a terminal stage, were found to have structural scoliosis with curves measuring between 20 and 80 degrees. 2. The common feature was severe and protracted rheumatoid disease. 3. The characteristics of the spinal curves are analysed; the longer curves may have been caused by muscle imbalance and the shorter curves possibly by asymmetrical involvement of the inter-apophyseal joints. 4. It is suggested that juvenile rheumatoid arthritis is an unusual
The results of surgery for Dupuytren’s disease can be compromised by the potential for disease recurrence and loss of function. Selecting which patients will benefit from repeat surgery, when to operate, and what procedure to undertake requires judgement and an understanding of patient expectations and functional needs. We undertook this study to investigate patient outcomes and satisfaction following repeat limited fasciectomy for recurrent Dupuytren’s disease. We prospectively identified all patients presenting with recurrence of Dupuytren’s disease who were selected for surgical treatment with repeat limited fasciectomy surgery between January 2013 and February 2015. Patients were assessed preoperatively, and again at a minimum of five years postoperatively. We identified 43 patients who were carefully selected for repeat fasciectomy involving 54 fingers. Patients with severe or aggressive disease with extensive skin involvement were not included; in our practice, these patients are instead counselled and preferentially treated with dermofasciectomy. The primary outcome measured was change in the Michigan Hand Outcomes Questionnaire (MHQ) score. Secondary outcomes were change in finger range of motion, flexion contracture, Semmes-Weinstein monofilament (SWM) values, and overall satisfaction.Aims

The clinical data from 19 patients with brucellar spondylitis and 15 with tuberculous spondylitis were compared. The former disease affects males whose occupations expose them to Brucella. The lumbar spine is usually involved and there are other symptoms of brucellosis. Tuberculous spondylitis is not usually accompanied by general symptoms. The dorsal spine is more frequently affected and may exhibit vertebral collapse and paraspinal abscesses. These differences permit a presumptive

Infantile idiopathic scoliosis is a structural scoliosis seen in infants, usually boys, with the major curve to the left in almost all cases, and almost invariably in the mid-or lower thoracic region. It occasionally disappears, but in general the curve tends to increase. In the absence of any discoverable

The hips of twenty full-term African neonates have been examined in detail to determine any anatomical factors which might explain the difference in the incidence of congenital dislocation of the hip in the African and in the Caucasian. Measurements included the degree of anteversion of the femoral neck and the acetabulum and the diameter and depth of the acetabulum. The acetabulum tended to be deeper and to vary within a much narrower range than that reported for Caucasians, lending indirect support to the theoretical role of acetabular dysplasia in the
1. One hundred patients with osteochondritis dissecans of the knee have been reviewed. Sixty-eight were male. Unilateral lesions were found in seventy-four. The average age at onset of symptoms was eighteen years. 2. The outstanding
1. Tumoral calcinosis and lipocalcinoma-granulomatosis are synonymous terms for the same entity. 2. The condition justifies inclusion as an important type of calcinosis and is to be differentiated from calcinosis universalis and calcinosis circumscripta. 3. It occurs during the first or second decades, large dense nodular masses forming in the periarticular tissues at the hips, shoulders and elbows. Smaller masses may have a wider distribution. 4. It has been reported to be a metabolic disease of obscure
The purpose of this report is not to describe a new condition but to remind those who seldom see smallpox of one of its most important and easily recognised complications. Bone infection can be late, almost silent and often most unexpected. It is usually symmetrical and almost always multiple. It does not affect the spine, pelvis and ribs, but does affect the arms, hands, legs and feet. It is destructive, unpreventable and untreatable. It ends with deformity but not with loss of life. The recognition of its
The main findings in this experimental work on rats fed on lathyrus odoratus (sweet-pea) meal are as follows:. 1. Growth is retarded. 2. The growth plate is disorganised and normal ossification at the metaphysis is interfered with. 3. The small blood vessels are seriously affected and probably contribute quite largely to the disorganisation and lack of calcification. 4. Alkaline phosphatase activity is increased. 5. Raising of the periosteum and laying down of new bone result in exostoses. The possible underlying
