This book serves as a definitive guide to diagnosing shoulder conditions for all levels of
orthopaedic surgeon with an interest in shoulder pathology and for junior surgeons in
training. It comes at a time when the knowledge regarding shoulder conditions has vastly
improved with the shoulder sub-speciality growing at a rapid pace in terms of practitioner
numbers procedures and evidence-base. However with the multitude of special tests for
shoulder conditions the clinician faces a variety of sensitivities and specificities of the
respective tests. It is unclear in most circumstances which single test is the best and
growing evidence confirms that a set of tests is superior for diagnosing shoulder conditions.
This forms the basis of cluster testing which is the key concept for the title and content of
this book. In many common shoulder diagnoses the preference for clusters has been reflected in
both experience and clinical evidence but for conditions where evidence for clusters is less
clear a consensus-based approach is utilised by the authors of this key resource for
diagnosing shoulder conditions.
