Nomograms derived from mathematical analysis indicate that the level of malunion is the most important determinant of changes in the moment arm of the knee, the plane of the ankle and alterations in limb length. Testing in five patients undergoing reconstruction showed a mean error of postoperative limb length of 2.2 mm (sd 0.8 mm), knee moment arm of 4.7 mm (sd 3.3 mm) and ankle angle of 2.6° (sd 2.3°). These nomograms provide the information required when assessing whether a particular degree of angulation may be accepted.

Cephamandole levels in serum and drain fluid were measured in 32 knee replacement operations to determine the benefit of an intravenous dose of antibiotic at the time of tourniquet deflation. Concentrations of cephamandole in drain fluid were directly proportional to the serum concentration at the time of tourniquet release. A 'tourniquet-release' dose of antibiotic increased drain fluid concentration threefold.

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.
