BACKGROUND The current consensus in the literature is that the anterolateral branch of the anterior humeral circumflex artery provides the main blood supply to the humeral head. While the artery is disrupted in association with 80% of proximal humeral fractures, resultant osteonecrosis is infrequent. This inconsistency suggests a greater role for the posterior humeral circumflex artery than has...

Introduction Posteriorly dislocated humeral head fracture has a great implication, as it is associated with high risk of avascular necrosis, limited access through the deltopectoral approach, and posterior approach to the posteriorly dislocated humeral fracture increases the risk to the remaining blood supply. Technical Tip Posteriorly dislocated humeral fracture is approached through deltope...

context functional humeral bracing remains the gold standard for treatment of humeral shaft fractures. there is an increasing trend in the literature to perform operative fixation of these fractures. evidence acquisition the aim of this systematic review was to compare the level one evidence for the outcome of non-operative with operative management of humeral shaft fractures in adults. a compr...

Background: We sought to characterize humeral-sided radiographic changes at a minimum of 2 years after reverseshoulder arthroplasty (RSA) to determine their association with specific implantation techniques.Methods: The immediate and most recent postoperative anteroposterior radiographs of 120 shoulders with primary RSAand a minimum of 2-years of radiographic follow-up were an...

BACKGROUND Collegiate baseball pitchers, as well as position players, exhibit increased humeral retrotorsion compared with individuals with no history of overhead sport participation. Whether the humeral retrotorsion plays a role in the development of throwing-related injuries that are prevalent in collegiate baseball pitchers is unknown. HYPOTHESES Humeral retrotorsion will be significantly ...

  Osteochondritis dissecans (OCD) is a common joint disorder in knee, ankle and elbow, however it can be rarely found in glenohumeral joint. In this study, we report an asymptomatic case of humeral head OCD, which was detected incidentally following a trauma. X-rays showed an area of lucency around an oval bony fragment measuring about 1 cm on the superior aspect of the humeral head. However, ...
