Shoulder arthroscopic procedures have become common in today's orthopedic practice. The safety of shoulder arthroscopy though well established, is not without complications both minor and significant. The true incidence of complications is difficult to identify in the current literature. However, as with all procedures, complications associated with shoulder arthroscopy do occur. General compli...

Background and purpose - Increasing numbers of shoulder arthroplasty are performed internationally. The predictors of intraoperative complications when implanting primary shoulder replacements are unknown. We determined the incidence of intraoperative complications during primary shoulder arthroplasty using the National Joint Registry of England, Wales, Northern Ireland and the Isle of Man (NJR...

TEACHING OBJECTIVES: To review the current concepts of shoulder arthroplasty. To review the normal post-operative appearance of shoulder arthroplasty including materials, design, and function. To review the imaging appearance of common complications. CONTENTS: Prosthesis material, design, and terminology Preoperative imaging assessment Normal post-operative imaging appearance Imaging findings o...

The reported rate of complications of reverse shoulder arthroplasty (RSA) seems to be higher than the complication rate of anatomical total shoulder arthroplasty.The reported overall complication rate of primary RSA is approximately 15%; when RSA is used in the revision setting, the complication rate may approach 40%.The most common complications of RSA include instability, infection, notching,...

Chronic unreduced anterior dislocations of the shoulder are rare. Arterial and neurological complications in chronic glenohumeral dislocations are even less frequent. We report three cases of old anterior shoulder dislocations. Open reduction is indicated for most chronic shoulder dislocations. Arterial lesions require urgent intervention with reconstruction. Conservative treatment is advised f...

displaced fracture of the acromion without associated shoulder injury occurs rarely. a 31-year-old gentleman presented with an isolated acromion fracture resulting from a direct trauma to the top of his left shoulder. open reduction and internal fixation using multiple pins was performed and the fracture was closed without complications. the patient achieved excellent shoulder function and rank...
