Lesser Tuberosity Avulsion Fracture: A Rare Case Report

INTRODUCTION: Lesser tuberosity avulsion fractures are rare and often missed. Patients often complain only of heaviness around the shoulder and some loss in range of motion. CASE REPORT: This is a rare case of a lesser tuberosity avulsion fracture with displacement. The patient was a 29-year-old male who suffered an injury to the right shoulder due to a fall. Post-fall, the patient developed typical heaviness and restrictions in the range of motion of his right shoulder. Radiographs initially taken were not true anteroposterior (AP) views. The fracture was primarily missed by another surgeon, after which on opting for a true AP radiographs, the fracture was diagnosed. The fracture was managed by an open deltopectoral approach. Fracture fragment was reduced to its footprint and was fixed using 2 × 4.0 mm cancellous screws. Post-surgery, the patient was advised 3 weeks of immobilization after which mobilization was started. By monitored physiotherapy, consistent results can be obtained without loss of reduction. In this case too, full ranges with strength were achieved by 3 months postoperatively. CONCLUSION: Such fractures often missed may cause loss of external rotation movements in the patient and eventually malunion of the fragment if displaced. Watchfulness and timely management of the fractures can give excellent results. This case report aims at increasing the awareness among the budding shoulder surgeons in identifying such injuries at the earliest, and the means of managing them.
