There are two main treatment options for left humeral tuberosity fracture: the first is conservative treatment: for left humeral tuberosity fracture after good alignment of the fracture and no obvious displacement, you can choose strictly conservative treatment, using triangular scarf suspension for six weeks, and then bone grafting and calcium treatment during the period. After six weeks, X-rays are repeated to determine the healing status of the fracture and to decide when to do functional exercises of the shoulder joint. This method is also suitable for patients who are older and less fit and do not have the means to tolerate surgery; the second type of treatment is surgery. For a left humeral greater tuberosity fracture followed by a well aligned fracture with no significant displacement, a strictly conservative treatment can be chosen, using a triangular scarf suspension for six weeks, followed by bone grafting and calcium therapy during that time. After six weeks, X-rays are repeated to determine the healing status of the fracture and to decide when to do functional exercises of the shoulder joint. This approach is also suitable for older patients who are less fit and do not have the means to tolerate surgery. If the fracture is significantly displaced after a large nodal fracture, most will require surgery. The surgery is performed under brachial plexus anesthesia or general anesthesia, with an incision and internal fixation of the fracture, with either titanium screws or absorbable screws.
