This new blood test for infection is based on the phenomenon of leukergy in which white cells agglomerate in the peripheral blood of patients with inflammatory diseases. It was used in 26 patients with proven bone or joint infection and was positive in 25. The leukergy test was more accurate than the ESR, white cell count or blood culture. The percentage of cells agglomerated correlated with the clinical severity of the infection and the test detected reactivation of the septic process better than the other haematological tests. It is a rapid and inexpensive method which is useful in the diagnosis and management of bone and joint infections.

A new method of recording the three-dimensional anatomy of the proximal femur from a single anteroposterior radiograph is described. This technique shows that in Perthes' disease the femoral head and neck are in significant anteversion and true varus. This anatomical configuration may be important in the pathogenesis and treatment of this disorder.

The results of excision of the distal ulna in 34 wrists of 25 patients with chronic rheumatoid arthritis of the distal radio-ulnar joint were reviewed. Rest pain had been cured or relieved in 77%, pain on pronation-supination in 86%, and limitation of pronation-supination in 90%, while 88% of the patients graded the result as excellent or fair. Despite this marked relief of symptoms, function of the upper limb was improved in only 25% of patients and remained unchanged in 60%. Ulnar subluxation of the carpus had occurred in 24% but seemed to be related to the destructive disease process rather than to the operation itself. The length of ulna resected was not related to the outcome of the operation.

An unusually wide pneumatic tourniquet has recently become available; we provide a simple formula for its use with a low but effective inflation pressure. A prospective, randomised and controlled trial in 600 lower limb and 150 upper limb operations is reported. The wide tourniquet (12.5 cm) was as effective at low pressure as was a conventional tourniquet (9 cm) inflated to significantly higher pressures. Fewer patients suffered from painful paraesthesiae after operation using the broad, low-pressure tourniquet.

A model of tourniquet ischaemia was developed in the hind limb of the rat, and the metabolic changes that occurred in the calf muscles were monitored by the non-invasive technique of phosphorus-31 nuclear magnetic resonance spectroscopy. During ischaemia the intramyocellular pH became acidic as the level of phosphocreatine declined and that of inorganic phosphate rose. Phosphocreatine was no longer detectable after approximately 2 hours and ATP was depleted after approximately 3.5 hours. Metabolic recovery was rapid (1 hour) if ATP was present when the tourniquet was released but was prolonged (3 or more hours) if ATP was depleted. Hourly release of the tourniquet for 10 minutes ensured the maintenance of ATP and rapid metabolic recovery. Release for intervals of only 5 minutes did not have the same protective effect and in fact worsened tissue pH during the period of tourniquet ischaemia. Heparin and corticosteroids were without effect during and after periods of tourniquet ischaemia.
