All patients who presented with symptoms and signs of frozen shoulder following documented traumatic anterior dislocation in the previous six months were included in the study. All cases were first time dislocations that were treated initially with simple reduction under sedation and early mobilisation (within two weeks). All patients had failed initial conservative treatment with physiotherapy and had persistent shoulder stiffness and pain. Our exclusion criteria included previous recurrent dislocations and patients who were unfit for a general anaesthetic. All patients had pre-operative glenohumeral radiographs (antero- posterior and Y-views) taken and were listed for manipulation under anaesthesia as soon as the inclusion criteria were met. The time from dislocation was recorded at the time of initial consultation.
