Assessment of the functional outcome of proximal humerus fracture following “PHILOS” plating

Abstract

Objective: The aim of our study was to evaluate the functional outcome using Constant-Murley scoring and grading system and complications of proximal humeral fractures in the elderly Indian population treated with proximal humerus internal locking system (PHILOS). Method: A prospective study was carried out in a tertiary care center in Kolhapur. A total number of 46 patients with fracture of proximal humerus (NEERs 2 part, 3part & 4part) were studied between January 2019 and Oct 2020. All were treated with PHILOS via deltopectoral approach. A mean follow up of 12 months was carried out, and evaluation was done with the help of Constant-Murley scoring and grading system. Result: The mean radiological union time was 16 weeks. The outcome was measured using Constant-Murley scoring and grading system. Average follow up period was 12 months with good patient satisfaction. Total of 11 patients out of 46 reported complications like Malunion (4.50%), Shoulder Joint Stiffness (17.80%), Infection (8.90%) and Implant Loosening (2.20%). No case of peripheral neuropathies reported in any of the patients. Conclusion: PHILOS plating via deltopectoral approach is a good treatment option showing good clinical outcome in the treatment of proximal humerus fracture (NEERs 2/3/4 part). It offers a more stable fixation and deltopectoral approach gives better exposure for the surgery.
