Abstract

Objective: To assess the functional outcome of proximal Humerus fractures after fixation with the PHILOS (Proximal Humerus Interlocking System) plating system in Sindh, Pakistan.
Methodology:This systematic case series was conducted at the Department of Trauma and Orthopedics, JPMC Karachi Pakistan from December 2017 to November 2019.A total of 81 patients of age 20 years and above of either sex presented with 3-part fracture, 4-part fracture or fracture-dislocation (according to the Neer classification system) with angulations of >45º or displacement of >1cm and fracture duration of less than two weeks were enrolled. Patients with pathological fractures secondary to tumors, infection and connective tissue disorders were excluded from the study. Passive elevation and rotation exercises were started on day 3rd day of operation. Active range-of-movement exercises were started at week 6. Final outcome was assessed on 24th week in terms of range of motion
Results: There were 25 (30%) patients with 3-part fracture, 41 (50%) with 4-part fracture and 15 (18%) patients had fracture dislocation. Right limb was involved in 55 (67%) patients and left limb was involved in 26 (32%) patients.Overall satisfactory outcome was found in 70 (86%) patients.
Conclusion: The functional outcome of PHILOS plate system in displaced proximal humerus fractures was found satisfactory.

Key words: Functional outcome, fracture proximal humerus, PHILOS plate.
