Magnetic resonance images (MRI) were obtained of 10 healthy volunteers and 70 patients suffering from various orthopaedic disorders. Selected images of soft tissue, joint, bone and spinal abnormalities are presented and their interpretation is described. Although we have been using MRI for only a very short time, it is already possible to see its advantages: it provides good images of soft-tissues, detailed pictures of bone marrow, and excellent visualisation of the
In a series of over 250 patients, four suffered peritoneal penetration by one of the pelvic pins while being put into a halo-pelvic apparatus. In each case a point on the iliac crest two to three centimetres posterior to the anterior superior iliac crest had been used as the anterior landmark for the positioning of the pelvic pin guide. To avoid this complication we advise that the anterior landmark for the guide should be the "tubercle of the crest", five centimetres or more posterior to the anterior superior iliac
1. A report is given of a family suffering from dystrophia myotonica and familial Paget’s disease of bone. 2. Radiological changes in the skull occur in both disorders, which are quite dissimilar. Thickening of the calvarium, however, may be common to both. 3. The serum alkaline phosphatase is high in Paget's disease and normal in dystrophia myotonica. 4. In one patient the Paget's disease was complicated by the development of multiple sarcomata. Sarcomatous involvement of the
The aims of this study were to review the surgical technique for a combined femoral head reduction osteotomy (FHRO) and periacetabular osteotomy (PAO), and to report the short-term clinical and radiological results of a combined FHRO/PAO for the treatment of selected severe femoral head deformities. Between 2011 and 2016, six female patients were treated with a combined FHRO and PAO. The mean patient age was 13.6 years (12.6 to 15.7). Clinical data, including patient demographics and patient-reported outcome scores, were collected prospectively. Radiologicalally, hip morphology was assessed evaluating the Tönnis angle, the lateral centre to edge angle, the medial offset distance, the extrusion index, and the alpha angle.Aims

Spinal injury at more than one level is not uncommon. Awareness of multilevel injury of the
The effect of storage at sub-zero temperatures and subsequent thawing was investigated in dissected muscles, tendons, limbs and
The majority of patients with chronic infantile and juvenile forms of spinal muscular atrophy survive to adult life. Forty-four patients have been reviewed at an average of 17 years after diagnosis. The subdivision of patients into four groups, based on the maximal physical function developed by the individual, correlates well with the onset and severity of secondary deformity of the limbs and
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
1. Seventy-five injuries of the cervical spine are reported. Fifty-three were dislocations and fracture-dislocations involving the third to the seventh segments. 2. The importance of careful examination in all neck injuries is stressed. 3. The injuries are divided into stable and unstable types and the causation of the instability is discussed. 4. Plaster immobilisation for more than six months failed in some patients to prevent recurrence of dislocation. 5. Operative treatment was advised in all cases of dislocation, the
We studied the bone mineral density (BMD) of 48 long-term survivors of highly malignant osteosarcoma who had been treated according to the chemotherapy protocols of the German- Swiss-Austrian Co-operative Osteosarcoma Study Group which include high-dose methotrexate. The mean age of the patients was 31 ± 4.2 years and the mean follow-up 16 ± 2.2 years. The BMD of the lumbar

Localised Langerhans-cell histiocytosis of bone (eosinophilic granuloma) is a benign tumour-like condition with a variable clinical course. Different forms of treatment have been reported to give satisfactory results. However, previous series all contain patients with a wide age range. Our aim was to investigate the effect of skeletal maturity on the rate of recurrence of isolated eosinophilic granuloma of bone excluding those arising in the

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 aim of this study was to evaluate improvements in the quality
and safety of paediatric spinal surgery following the implementation
of a specialist Paediatric Spinal Surgical Team (PSST) in the operating
theatre. A retrospective consecutive case study of paediatric spinal operations
before (between January 2008 and December 2009), and after (between
January 2012 and December 2013) the implementation of PSST, was
performed. A comparative analysis of outcome variables including
surgical site infection (SSI), operating time (ORT), blood loss (BL),
length of stay (LOS), unplanned staged procedures (USP) and transfusion
rates (allogenic and cell-saver) was performed between the two groups.
The rate of complications during the first two postoperative years
was also compared between the groups.Aims
Patients and Methods
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
