Background: Proximal humeral fracture is defined as fractures occurring at or proximal to the surgical neck of the humerus. It affects 2.4% of women over the age of 75 years. It is the commonest fracture affecting the shoulder girdle in adults and its incidence is rising. For displaced fractures that meet surgical indications, deltopectoral approach is the most common approach for plate fixation of proximal humeral fractures. Deltoid splitting approach offers advantages of better exposure and implant placement for fixation of the fracture and early mobilization of the shoulder joint.

Methods: This is a comparative study of 30 cases of proximal humerus fractures treated by surgical fixation through deltoid splitting approach and 30 cases treated by delto pectoral approach. Patient of both sexes belonging to adult age group in general population presenting with proximal humerus fracture to the orthopaedic department of Bapuji Hospital and Chigateri General hospital attached to J.J.M. Medical College, Davangere. The period of survey extends from December 2020 to December 2022. The final results were evaluated using constant Murley score periodically. This constant Murley score ranges from 0 to 100 points representing worst and shoulder function respectively.

Results: No statistically significant difference was observed in outcome with regard to mechanism of injury, side of fracture and type of fracture with both deltoid splitting approach and delto pectoral approach.

Conclusions: The treatment of proximal humeral fractures with a proximal locking plate is reliable using both approaches. No significant difference found in functional outcome of proximal humerus fracture following deltoid split and deltopectoral approach on serial follow up.
