This book provides an up-to-date overview of the latest evidence regarding shoulder stiffness or frozen shoulder. All aspects are covered: epidemiology, etiology, anatomy and biomechanics, clinical symptoms, histology and laboratory tests, physical examinations, imaging studies and the various conservative and surgical treatment options. The book is published in cooperation with ISAKOS and reflects the conclusions of the Consensus Meeting of the ISAKOS Upper Extremity Committee in Amsterdam in May 2014, which brought together global opinion leaders in the field. Frozen shoulder itself remains shrouded in mystery. There is ongoing uncertainty over its causation and continuing relative neglect due to the belief that it is a self-limited disease despite the evidence that most patients fail to achieve complete recovery, with many experiencing persistent pain and stiffness. Shoulder Stiffness: Current Concepts and Concerns provides an excellent summary of present knowledge regarding frozen shoulder and will be of value to all who manage the condition.
