Although there is correlation between the histological and radiological features of intraosseous lipomas in general, some discrepancies occur in the radiological appearances of lipomas in different sites. The evidence that these lesions are true benign tumours of fat is controversial. Several aetiological factors have been implicated in their development. The constant location of os calcis lesions at the critical angle suggests an aetiology that may be related to biomechanical lines of stress. In other instances it is possible that involution of pre-existing lesions may lead to the development of lipomas.

The sternoclavicular joint is vulnerable to the same disease processes as other synovial joints, the most common of which are instability from injury, osteoarthritis, infection and rheumatoid disease. Patients may also present with other conditions, which are unique to the joint, or are manifestations of a systemic disease process. The surgeon should be aware of these possibilities when assessing a patient with a painful, swollen sternoclavicular joint.

Corticosteroid injections for Morton neuroma can be of symptomatic benefit for at least three months.

The varicograms of 128 legs were reviewed by a panel of two vascular surgeons and a radiologist with a specialist vascular interest. Varicography effectively elucidates the anatomical basis of recurrence. Recurrent varicose veins were associated with (i) technically unsatisfactory surgery at the saphenofemoral junction (66 per cent) and (ii) failure to remove the long saphenous vein in the thigh (60 per cent). A new classification is offered as a basis for comparison of series, audit and surgical training.
