Background: The deltopectoral approach is the most commonly used approach for the reduction and fixation of proximal humerus fractures. But it provides inadequate access to the posteriorly displaced fragments in comminuted fractures and to the lateral surface where the plate is to be applied. These disadvantages can be obviated by a direct lateral transdeltoid approach. There have been concerns regarding postoperative axillary nerve palsy and deltoid dysfunction with this approach. This study had been conceptualized to assess the outcome of fixation of proximal humerus fractures with deltoid splitting lateral approach.
Methods: A total of 20 patients with Neer’s type 2 and 3 fractures of proximal humerus were included in this study. Lateral transdeltoid approach was used for exposure, with either an extended incision or a “two window” less invasive incision, depending upon the fracture anatomy. Functional outcome was assessed using the Constant Murley shoulder score.
Results: The fracture was classified as Neer’s type 2 in 30% and type 3 in 70% of the cases. The mean Constant Murley score at final follow up was 78 (range 64-84). Graded according to the Constant shoulder score grading criteria, the results were excellent in 60%, good in 35% and fair in 5% of the cases. No case of postoperative axillary nerve palsy was encountered.
Conclusions: The functional outcome was either excellent or good in 95% of the cases and no case of axillary nerve palsy was seen. Hence, Lateral transdeltoid approach is a convenient and useful approach to proximal humerus fractures.
