Arthrography of the hip has been practised for over 40 years, but its value as a useful method of investigation has not been generally accepted. Difficulties in technique and interpretation may explain some lack of appreciation. Arthrography of any joint should be practised regularly to facilitate technique and to gain the necessary experience of interpretation. The surgeon or radiologist interested in this technique should have access to a regular flow of patients. The arthrogram can produce valuable information regarding the pathology of the condition which may influence treatment or prove of interest in retrospective study. In congenital dislocation of the hip routine arthrography in the past led to greater understanding of intra-articular obstruction and to the appreciation of some complications of treatment in the early moments of life. Dr Grech has made a stimulating contribution in this monograph which describes technique in the greatest detail. He provides useful guidelines for interpretation and detailed case records which will attract clinical interest. All hip conditions where arthrography might be indicated are described. The author's work is addressed primarily to radiologists or surgeons who might wish to practise arthrography, but there is much in this monograph which will interest those who are already familiar with the technique.
