Lesser Tuberosity Avulsion Fracture: A Rare Case Report

Area of Science:

• Orthopedic surgery
• Sports medicine
• Traumatology

Background:

• Lesser tuberosity avulsion fractures are uncommon injuries.
• These fractures are frequently misdiagnosed due to subtle presentation and initial suboptimal imaging.
• Patients typically report shoulder heaviness and reduced range of motion.

Observation:

• A 29-year-old male sustained a displaced lesser tuberosity avulsion fracture after a fall.
• Initial radiographs were not true anteroposterior (AP) views, leading to a missed diagnosis.
• A subsequent true AP view confirmed the fracture, which was then surgically managed.

Findings:

• The fracture was treated via an open deltopectoral approach with screw fixation.
• Post-operative immobilization was followed by a structured physiotherapy regimen.
• The patient achieved full range of motion and strength within three months.

Implications:

• Early and accurate diagnosis of lesser tuberosity avulsion fractures is essential to prevent malunion and functional loss.
• This case highlights the importance of appropriate radiographic views and surgical awareness.
• Timely intervention and rehabilitation can lead to excellent functional recovery in these rare injuries.
