Treatment of Greater Tuberosity Fracture: Evidence-Based Strategies for Treatment and Best Practices.

» Isolated greater tuberosity (GT) fractures account for approximately 20% of all proximal humerus fractures. » Displaced GT fractures can compromise the rotator cuff biomechanics and behave as rotator cuff deficient shoulders, leading to weakness (external rotation and scaption strength), loss of range of motion (elevation, abduction, external rotation), and subacromial impingement. » Most nondisplaced to minimally displaced fractures (<5 mm) can be treated nonsurgically with good outcomes. Secondary displacement of GT fractures is low, but the presence of associated shoulder instability predisposes patients to a higher risk, and thus, these patients should be monitored closely. » Displaced fractures benefit from surgical treatment. A tension band construct or buttressing mechanism is required to neutralize the deforming force of the posterior and superior rotator cuff on fracture fixation. » There is no consensus on the surgical approach (arthroscopic vs. open) and type of fixation (plate, screws alone, suture anchor repair, or hybrid fixation) for the surgical treatment of these fractures. Each fixation option has its own unique profile of advantages and risks, emphasizing the importance of individualized management. » Small (<1 cm) avulsion or depressed type fractures are amenable to arthroscopic treatment with suture anchor repair, with or without screw fixation, resulting in good outcomes. » Open repair is more common in split type fracture patterns or fractures with a large fracture fragment. There is no consensus on the surgical approach (deltopectoral vs. anterolateral or lateral deltoid approach) for open repair.
