Functional outcome after primary hemiarthroplasty in three o
Background : Several modalities of treatment are being used for the management of proximal humerus fractures. Primary hemiarthroplasty in proximal humerus fracture is indicated in three or four part fracture or fracture dislocations. It is also indicated if fracture involves a large area of articular cartilage loss and viability of head is doubtful. We studied the functional outcome of hemiarthroplasty in comminuted proximal humerus fracture.

Materials and Methods : 29 patients of three or four part proximal humerus fractures, (according to Neer's classification) who underwent primary shoulder hemiarthroplasty were included in this retrospective study. 20 patients were of more than 55 years of age. Functional evaluation based on Constant score and radiological assessment by periodic X-rays were done. All patients were operated in a 'beach chair position'. The lesser and greater tuberosities were dissected with their tendinous attachments and were later reattached to the proximal humerus for stability of the prosthesis. Cemented prosthesis was used in all cases.

Conclusion : This study showed that hemiarthroplasty in a grossly comminuted proximal humerus fracture is a viable alternative to osteosynthesis. Tuberosity healing plays a main role in good range of motion and better functional outcome after shoulder hemiarthroplasty.
