This third edition of Hypermobility of Joints follows the same format as its successful predecessors. The aim of those editions was to provide an overview of hyperlaxity of joints and this edition follows that aim by describing the most recent research and new developments in biochemistry as well as providing practical advice on clinical features and management. Further chapters provide illustrative case histories, a review of hypermobility in the performing arts and sports and an outline of heritable hypermobility syndromes. Hypermobility of Joints has implications for a wide number of specialties although it will particularly be of interest to rheumatologists, orthopedic surgeons and medical geneticists.
