This paper reports a prospective study of the value of ultrasonography in detecting lesions of the lumbar
A thoracolumbar gibbus is an uncommon but potentially dangerous feature of achondroplasia. In a series of unselected South African Negro achondroplasts, nine out of 17 had an abnormality of this type. In contrast, only one girl out of 20 affected individuals of European or mixed ancestry had a gibbus. It is likely that the high frequency of this deformity in South African Negro achondroplasts is the result of the traditional practice by which an infant is carried on the mother's back, with the legs straddling her waist and the

There has been an increase in the incidence of bone and joint tuberculosis (BJTB) in The Netherlands and we have carried out an epidemiological study in order to find an explanation for this increase. Data from 1993 to 2000 from The Netherlands Tuberculosis Register (NTR) were used. In 1993 there was a total of 52 patients with BJTB. This figure increased gradually to 80 in 1999 before decreasing to 61 in 2000. There was a total of 12 447 patients with tuberculosis; BJTB was found in 532, accounting for 4.3% of all cases and 10.6% of all extrapulmonary cases. Localisation in the
The nerve roots of the cauda equina may be visualised by contrast-enhanced CT scans and by surface-coil MRI. We have identified the pattern of anatomy from L2-L3 to L5-S1 in 10 human cadaver specimens and correlated this with anatomical dissections. Individual roots are slightly more distinct on contrast-enhanced CT than on surface-coil MRI. There is a crescentic oblique pattern of nerve roots at the lower lumbar levels which is still apparent in the more crowded proximal sections. In all cases, the axial images correlated precisely with the dissections. Current imaging modalities can help the clinical understanding and management of abnormalities in this region of the

A syndrome of back and loin pain produced by impingement of the lowest rib against the iliac crest is described in six patients. All had noticed a significant loss of height and five had osteoporosis of the
The aim of this study was to report a retrospective, consecutive
series of patients with adolescent idiopathic scoliosis (AIS) who
were treated with posterior minimally invasive surgery (MIS) with
a mean follow-up of two years ( We prospectively collected the data of 70 consecutive patients
with AIS treated with MIS using three incisions and a muscle-splitting
approach by a single surgeon between June 2013 and February 2016
and these were retrospectively reviewed. There were eight male and
62 female patients with a mean age of 15 years (Aims
Patients and Methods
Magnetic resonance imaging (MRI) was used to compare the appearance of the
Twenty-four children with infantile or juvenile idiopathic scoliosis had their
Twenty-eight patients with adolescent idiopathic scoliosis treated by anterior spinal fusion with Dwyer instrumentation were reviewed. The average length of follow-up was 6.9 years. This technique produced better correction of lateral curvature and rotation than Harrington instrumentation, particularly in the thoracolumbar and lumbar region. The length of
Fifty-four adults with eighty hips affected by congenital disease which had not been treated have been reviewed. Fifty-nine per cent of forty-two dislocated hips had fair or poor grading scores. The incidence of osteoarthritis was markedly increased in the presence of a well-developed false acetabulum. Unilateral dislocation led to valgus deformity and degenerative changes in the ipsilateral knee in seven of twenty-two patients. Dislocation did not increase the incidence of symptomatic lumbar spondylosis. The height of the dislocated head on the ilium was not found to be related to the prognosis for the hip, the knee or the lumbar
1. A high incidence of paraplegia following operations for the correction of severe scoliosis in adults led to an investigation of the normal blood supply of the human spinal cord. 2. This entailed three methods of study: micro-dissection of the vessels of the spinal cord in thirty-five cadavers; radiological measurements of the spinal canal in fifty healthy subjects; and a study of the macerated
1. Ten children with scoliosis and cerebral palsy of various types have been reviewed. All underwent operation for correction and stabilisation of the spinal curve, and spinal fusion. 2. Three of the ten patients required supplemental surgery in the form of regrafting, with or without reinsertion of Harrington rods. All have shown considerable correction of the curve, and in all cases the fusion appears to be consolidated. Operation has given these children stable
Early decompression in Pott's paraplegia gives encouraging results. It produces speedy recovery from paraplegia and ensures rapid healing of the lesion. Lateral extrapleural decompression without fusion for lesions of thoracic vertebrae is safe and satisfactory. It gives adequate exposure of the anterior and posterior parts of the vertebral bodies and of the theca, without endangering the stability of the
1. A twenty-five-year-old man who developed neuropathic arthritis because of indifference to pain is described. He presented at the age of thirteen with degenerative changes in the light knee with analgesia only in the right leg below the knee. 2. A painless fracture of the ulna developed non-union and was associated with a neuropathic arthritis of the elbow joint. 3. Later the other knee and the lumbo-sacral

We have reviewed 41 patients with pustulotic arthro-osteopathy (PAO), all having both the typical skin rash of pustulosis palmaris et plantaris and bone lesions. The most common bones affected were the clavicle, sternum and ribs. Changes in the clavicle started, not as an enthesopathy, but with periosteal bone formation, indicative of a bone marrow disorder. About 30% of the patients also had lesions in the
The midsagittal and interpedicular diameters and the trefoil shape of lumbar vertebrae of known age at death were measured in skeletons from a population aged between 1 and 70 years. All the trefoil configurations were at L5 with the exception of one at L4. The overall prevalence was 25%, but this shape was not generally apparent until adulthood. The midsagittal diameter in the trefoil canals was found to be significantly smaller than that in the unaffected canals. This did not change significantly after six years of age indicating that the cause of the trefoil configuration is probably present early in life. The trefoil shape was no more common in the
