We have investigated whether patients with adolescent-onset idiopathic scoliosis (AIS) are more likely to have a low body-weight. Measurements of weight, height and body mass index (BMI) were made in 44 young women with AIS and compared with age- and gender-adjusted normative data. The body mass criteria of the International Classification of Diseases for eating disorders was used to determine how many patients were within the range considered to be ‘eating disordered’. Compared with the normative data, the AIS group did not differ significantly in terms of height, (p = 0.646), but they were significantly lighter (p < 0.001) and had significantly lower BMI scores (p < 0.001); 25% of the series had BMI scores which were within the range considered to be anorexic.

The relationship between a diagnosis of AIS and low body-weight may indicate disordered eating and is thus a cause for concern, particularly in the light of the well-established relationship between eating psychopathology and osteoporosis. Aspects of organic health may need to be considered in addition to the cosmetic deformity.

Surgical decompression of the spinal canal is presently accepted worldwide as the method of treatment for thoracolumbar burst fractures with neurological deficit in the belief that neurological recovery may be produced or enhanced. Our clinical and laboratory experience, however, indicates that the paralysis occurs at the moment of injury and is not related to the position of the fragments of the fracture on subsequent imaging. Since the preoperative geometry of the fracture may be of no relevance, our hypothesis, backed by more than two decades of operative experience, is that alteration of the canal by ‘surgical clearance’ does not affect the neurological outcome.

We have reviewed the existing world literature in an attempt to find evidence-based justification for the variety of surgical procedures used in the management of these fractures. We retrieved 275 publications on the management of burst fractures of which 60 met minimal inclusion criteria and were analysed more closely. Only three papers were prospective studies; the remainder were retrospective descriptive analyses. None of the 60 articles included control groups. The design of nine studies was sufficiently similar to allow pooling of their results, which failed to establish a significant advantage of surgical over non-surgical treatment as regards neurological improvement. Significant complications were reported in 75% of papers, including neurological deterioration. Surgical treatment for burst fracture in the belief that neurological improvement can be achieved is not justified, although surgery may still occasionally be indicated for structural reasons. This information should not be withheld from the patients.

It has been suggested that reamed intramedullary nailing of the femur should be avoided in some patients with multiple injuries. We have studied prospectively the effect of femoral reaming on the inflammatory process as implicated in the pathogenesis of acute respiratory distress syndrome (ARDS) and multiple-organ failure (MOF). We studied changes in the levels of serum interleukin-6 (IL-6) (proinflammatory cytokine), neutrophil CD11b (C3) receptor expression (activated neutrophil adhesion molecule), serum soluble intracellular adhesion molecule (s-ICAM-1), serum soluble E-selectin (the soluble products of endothelial adhesion molecules) and plasma elastase (neutrophil protease) in a series of patients with femoral fractures treated by nailing. We have also compared reamed nailing with unreamed nailing.

We found that the levels of serum IL-6 and elastase rose significantly during the nailing procedure indicating a measurable ‘second hit’. There was no clear response in leukocyte activation and no difference in the release of endothelial adhesion molecule markers. There was no significant difference between groups treated by reamed and unreamed nailing. Although clinically unremarkable, the one patient who died from ARDS was shown to be hyperstimulated after injury and again after nailing, suggesting the importance of an excessive inflammatory reaction in the pathogenesis of these serious problems.

Our findings have shown that there is a second hit associated with femoral nailing and suggest that the degree of the inflammatory reaction may be important in the pathogenesis of ARDS and MOF.

1. A new piece of equipment, the quantitative colour television image analyser, has been introduced as providing a superior method for measuring bone density.

2. This method produces not only a numerical result but also a pattern of density distribution in the form of a seven colour contour map.

3. The changes in twenty rheumatoid hands at an interval of one year have been measured. The metacarpals and proximal phalanges always lose bone, but the metacarpo-phalangeal joint may gain in density if the disease process is far advanced. Some areas can lose 50 per cent of bone in one year.
