1. Evidence is presented that the basic lesion in scoliosis is relative lengthening of the anterior components of the spine compared with the posterior elements. 2. The logical treatment is to reduce this relative lengthening either by lengthening the posterior elements or shortening the anterior elements. This may be achieved by anterior lumbar wedge osteotomy or by epiphysiodesis; and correction of lumbar lordosis can improve a thoracic scoliosis

Aims

The aim of this study was to explore the prognostic factors for postoperative neurological recovery and survival in patients with complete paralysis due to neoplastic epidural spinal cord compression.

The incidence of congenital dislocation of the hip in 156 children with infantile idiopathic scoliosis was 6.4 per cent, approximately 10 times its frequency in the general population. In both of these deformities there was a predominance of girls (eight girls: two boys). In unilateral dislocation of the hip the convexity of the thoracic scoliosis was on the same side as the dislocation. Eight out of the 10 children with both deformities also had plagiocephaly

In our practice sequestration of the shafts of long bones in children because of acute osteomyelitis continues to be a problem. Conventional procedures for bone grafting are likely to fail. Vascularised grafts with microvascular anastomosis are technically demanding with a high rate of failure. Transfer of the rib on its vascular pedicle to achieve anterior fusion in the thoracic spine is now well established and the length of the pedicle available is adequate to allow grafting of a diaphyseal defect in the humerus. We describe the successful use of this procedure in two patients

We describe a method for approaching the lower cervical and upper thoracic spine, the brachial plexus and related vessels. The method involves the elevation of the medial corner of the manubrium, the sternoclavicular joint, and the medial half of the clavicle on a pedicle of the sternomastoid muscle. We have used this exposure in 17 cases with few complications and good results. Its successful performance requires high standards of anaesthesia, surgical technique and postoperative care

In 139 patients with burst fractures of the thoracic, thoracolumbar or lumbar spine, the least sagittal diameter of the spinal canal at the level of injury was measured by computerised tomography. By multiple logistic regression we investigated the joint correlation of the level of the burst fracture and the percentage of spinal canal stenosis with the probability of an associated neurological deficit. There was a very significant correlation between neurological deficit and the percentage of spinal canal stenosis; the higher the level of injury the greater was the probability. The severity of neurological deficit could not be predicted

Aims

Severe spinal deformity in growing patients often requires surgical management. We describe the incidence of spinal deformity surgery in a National Health Service.

A modified transthoracic approach to the thoracic vertebral column is described. In this method, the parietal pleura is detached from the chest wall and retracted with the visceral pleura and its contents. A direct approach to the vertebral bodies is thus achieved without transgression of the intrapleural space. The technique can be extended to include exposure of the thoracolumbar spinal column, utilising a thoracoabdominal approach with extrapleural and extraperitoneal dissection. Management of the costophrenic detachment is thus simplified. This approach has significant advantages for orthopaedic, vascular and neurosurgical procedures

Aims

The aim of this paper is to describe the impact of COVID-19 on spine surgery services in a district general hospital in England in order to understand the spinal service provisions that may be required during a pandemic.

1. The radiographic appearance of normal thoracic and lumbar vertebrae at 15-degree intervals of rotation is described. Each image can be identified by its characteristic features. 2. The appearance on antero-posterior radiographs of apical vertebrae in scoliosis closely resembles the normal at each phase of rotation, on the basis of which an image-matching method is proposed for estimating rotation in scoliosis. 3. The method gives only approximate values of rotation but has the advantage of being able to monitor rotation through 90 degrees

Two siblings with spondylothoracic dysostosis, and two siblings and three unrelated children with spondylocostal dysostosis are described. Both conditions are inherited and characterised by malformed thoracic and lumbar vertebrae. Spondylothoracic dysostosis produces "crab-like" deformities of the ribs, and is usually fatal during early infancy due to respiratory failure. Spondylocostal dysostosis causes short-trunked dwarfism but does not usually reduce life expectancy. These clinical features are distinct from congenital scoliosis, although all three conditions are associated with a particular group of malformations

The effect of early fusion on growth of the spine has been studied in rabbits. Free periosteal grafts from the tibia were transplanted either posteriorly between the spinous and articular processes or postero-laterally between the articular and transverse processes. Sound bony fusion was achieved in both the thoracic and the lumbar spine. Spinal fusion caused local narrowing and wedging of the intervertebral spaces, followed by retardation of growth and wedging of the vertebrae. A progressive structural scoliosis developed after unilateral postero-lateral fusion and a lordosis developed after posterior fusion

The following preliminary conclusions seem possible. 1. In early cases of Pott's disease of the thoracic spine in children the treatment should include chemotherapy, recumbency and costo-transversectomy. An exception may be made if severe destruction has led to subluxation of the column, when more radical surgery is indicated. 2. Combination of conservative treatment with costo-transversectomy can prevent spread of the disease along the vertebral column, and can lead to regression of this "spondylitis anterior.". 3. The abscess can be totally eradicated and the risk of recrudescence therefore diminished

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 etiology it is termed "idiopathic" and it is believed not to differ in essentials from the more common adolescent scoliosis. Lumbar idiopathic scoliosis has a good prognosis as to deformity, but leads more often than any other curvature to degenerative arthritis and pain in later life

Aims

Now that we are in the deceleration phase of the COVID-19 pandemic, the focus has shifted to how to safely reinstate elective operating. Regional and speciality specific data is important to guide this decision-making process. This study aimed to review 30-day mortality for all patients undergoing orthopaedic surgery during the peak of the pandemic within our region.

High myelomeningocele lesions do not preclude an acceptable level of functional walking provided that an integrated programme of surgical treatment and bracing is adopted. Clinical analysis of 100 patients with myelomeningocele shows that the development of the "swivel walker" and "hip guidance orthosis" has been associated with an improved level of function. Over 30 per cent of patients with thoracic lesions and 68 per cent of those with lumbar lesions achieved independent walking. For this reason the criteria used at present by paediatricians to govern the selection of infants for non-active treatment may require reconsideration

A study of cadaveric vertebral biopsy and a review of 100 clinical biopsies has shown that needles and trephines producing tissue specimens of two millimetres or more in diameter can be expected to give a high degree of diagnostic accuracy. The erythrocyte sedimentation rate was a more useful screening investigation than were estimations of serum alkaline phosphatase. The complications are described. It is suggested that patients with painful thoracic metastases and evidence of progressive cord compression should have early decompression after open biopsy if further neurological compromise is to be prevented

1. Experience in the treatment of tuberculous disease of the spine, hip and knee by combined constitutional, antibiotic and operative measures is described. 2. In patients with tuberculosis of the spine, especially in the thoracic region and when perispinal abscess formation is a prominent feature, the treatment helps to ensure stable ankylosis in the type of case in which it otherwise might not occur. 3. In children with tuberculosis of the hip and in adults and children with tuberculosis of the knee it is usually possible to save the joint and to restore function, provided the joint has not been destroyed before treatment is begun
