Isolated avulsion fracture of the lesser tuberosity of the humerus. Report of two cases.

We describe two cases of isolated avulsion fracture of the lesser tuberosity: this is an extremely rare pathology, and to our knowledge only 34 cases have been reported in the literature. In the present cases, standard radiography and computed tomography clearly evidenced the detached bone fragments. As the patients refused surgical reduction, they were treated conservatively. Outcomes were successful, and three months after injury both of them returned to normal activity with only slight limitation in external rotation. At their check-up six-months after injury the patients continued to carry on normal activity, in both cases their limitation in external rotation had decreased even further. Both patients were pain-free and satisfied with their treatment outcome.
