We investigated 21 pairs of twins for zygosity and idiopathic scoliosis. DNA fingerprinting confirmed that 13 pairs were monozygotic and eight were dizygotic. There was concordance for idiopathic scoliosis in 92.3% of monozygotic and 62.5% of dizygotic twins. Of the 12 pairs of monozygotic twins concordant for idiopathic scoliosis, six showed discordant curve patterns but eight had differences in Cobb angle of less than 10°. Seven of the ten pairs of monozygotic twins had similar back shapes. Our findings suggest that there is a genetic factor in the
While preoperative bloodwork is routinely ordered, its value in determining which patients are at risk of postoperative readmission following total knee arthroplasty (TKA) and total hip arthroplasty (THA) is unclear. The objective of this study was to determine which routinely ordered preoperative blood markers have the strongest association with acute hospital readmission for patients undergoing elective TKA and THA. Two population-based retrospective cohorts were assembled for all adult primary elective TKA (n = 137,969) and THA (n = 78,532) patients between 2011 to 2018 across 678 North American hospitals using the American College of Surgeons National Quality Improvement Programme (ACS-NSQIP) registry. Six routinely ordered preoperative blood markers - albumin, haematocrit, platelet count, white blood cell count (WBC), estimated glomerular filtration rate (eGFR), and sodium level - were queried. The association between preoperative blood marker values and all-cause readmission within 30 days of surgery was compared using univariable analysis and multivariable logistic regression adjusted for relevant patient and treatment factors.Aims

In 15 consecutive patients with slipped capital femoral epiphysis we recorded height, weight and skeletal maturity. Sexual maturity was assessed clinically and biochemically, and Harris's hypothesis that there is an increased ratio of serum growth hormone to oestrogen was tested in comparison with 15 age and sex matched controls. We found no difference in skeletal or sexual maturity between the groups, or any overt endocrine abnormality in the patients. However almost half the patients with slipped epiphysis were over the 90th weight percentile, suggesting that mechanical factors such as obesity are more important
Arthroscopy of the hip revealed a torn acetabular labrum in seven young patients. Three of them had had an acute onset of symptoms during sporting activities. On examination all seven patients had pain on passive flexion and medial rotation of the joint. All but one of the tears were located on the posterosuperior portion of the labrum, and, in the acute cases, vascular dilatation around the tear was observed. In these cases, repeated arthroscopy several months later showed that the vascular changes had disappeared, but the tear was still present. The
The term "congenital scoliosis" contributes little to our understanding of
Iliopsoas pathology is a relatively uncommon cause of pain following total hip arthroplasty (THA), typically presenting with symptoms of groin pain on active flexion and/or extension of the hip. A variety of conservative and surgical treatment options have been reported. In this retrospective cohort study, we report the incidence of iliopsoas pathology and treatment outcomes. A retrospective review of 1,000 patients who underwent THA over a five-year period was conducted, to determine the incidence of patients diagnosed with iliopsoas pathology. Outcome following non-surgical and surgical management was assessed.Aims

The Blackburne and Peel method of assessing the position of the patella was applied to 185 knees with Osgood--Schlatter disease in 125 patients. The normal index of 0.80 was confirmed in 73 control knees. The average index in the knees with Osgood--Schlatter disease measured 1.01 (patella alta) boys and 0.91 in girls. The value increased to 1.06 in boys with radiological evidence of loose ossicles in the tibial tuberosity or the patellar tendon. This finding indicates that the strong pull of the well-developed quadriceps muscle is probably the most important
Throughout 1976 orthopaedic surgeons in three regions of England forwarded details of all new patients with Perthes' disease attending outpatient clinics or admitted as inpatients. The incidence in the Mersey region (11.1 per 100 000 children under fifteen years) was twice that in Wessex (5.5) with Trent having an intermediate incidence (7.6). The ratio of male to female incidence varied between the regions as did the age distribution of male cases. These findings point to the importance of environmental factors in the
1. Congenital vertical talus is described and the criteria for diagnosis are emphasised. The need for its distinction from other forms of convex pes valgus is stressed. 2. The operative technique of Stone for Lloyd-Roberts (1963) is detailed and the results of seven such operations are examined. 3. Departure from the technique in any respect has resulted in an unsatisfactory outcome, whereas stringent observation of the operative details has resulted in uniformly good results in four patients. 4. Certain aspects of diagnosis, differential diagnosis,

To report the outcome of spinal deformity correction through anterior spinal fusion in wheelchair-bound patients with myelomeningocele. We reviewed 12 consecutive patients (7M:5F; mean age 12.4 years (9.2 to 16.8)) including demographic details, spinopelvic parameters, surgical correction, and perioperative data. We assessed the impact of surgery on patient outcomes using the Spina Bifida Spine Questionnaire and a qualitative questionnaire.Aims

Four cases of slipped upper femoral epiphyses in patients with intracranial tumours causing hypopituitarism and chiasmal compression are presented. Detailed endocrine studies in three cases showed severe deficiencies of growth hormone as well as of gonadotrophin and sex hormones. The literature is reviewed and the
1. A case is described of severe birth injury to the sternomastoid muscle in a breech-delivered two-day-old infant. The affected muscle showed widespread haemorrhage, fragmentation and necrosis of its fibres, and disruption and disorganisation of the endomysial sheaths. 2. Disruptive muscular trauma of this type is known to lead to florid fibroblastic proliferation with formation of a large mass of scar tissue. It is suggested that the "sternomastoid tumour" of infancy develops as a sequel to such trauma occurring during birth. 3. The theories of birth trauma and of ischaemia, in the
Six children who complained of pain and stiffness in the back had been treated with lumbar punctures between six and ten years before they came under observation. They were found to have intrathecal epidermoid tumours in the lumbar region which are presumed to have arisen from implanted skin fragments. The main evidence for this assumption is that since 1956 sixteen patients with lumbar epidermoid tumours in patients who had had previous lumbar punctures have been reported, in contrast to the five patients with lumbar epidermoid tumours recorded before that date. This suggests that there is an additional
Reports of spondylolysis in vertebrae other than those of the lower lumbar spine are rare. We report 32 patients with upper lumbar spondylolysis who have been studied clinically, radiologically and scintigraphically. Twenty patients had bilateral lesions, and seven of those with unilateral lesions had structural changes or anomalies in the opposite posterior arch. Positive scans were found to be associated with a short clinical history, and indicated stress-related lesions. Our findings suggest that mechanical factors may play a role in the
