An analysis of functional outcome and complications of proximal humeral interlocking system plating for displaced proximal humeral fractures a prospective study

Abstract

Background: The study was conducted to assess functional outcome and complications of Proximal Humerus Inter Locking System (PHILOS). Plating in displaced proximal humeral fractures by Constant-Murley (Subjective and Objective) score.Materials and Methods: The study was conducted on 60 patients with displaced proximal humeral fractures operated with Proximal Humerus Inter Locking System. Among 60 patients 24 females, 36 males; mean age 50.64 years range (26-70yrs). All patients were put on same physiotherapy program following internal fixation with the PHILOS plate. The patients were assessed clinically and radio graphically at regular intervals of 6 weeks, 12 weeks and 6 months. Functional outcome was assessed using the Constant- Murley score. Complications during the follow-up period were recorded.Results: In our series of 30 patients 2-part fractures were more common accounting 60 % compared to 3-part (20%) and 4-part (20%). Fractures united in all patients. The most frequent complication seen was shoulder stiffness in 6 patients. Excellent functional outcome seen in 18 (30%) cases, good 24 (40%) cases, fair 12(20%) cases, poor 6(10%) casesConclusion: Fixation of proximal humerus fractures with proximal humerus locking plates is associated with satisfactory functional outcomes in 2-part and 3-part and 4 part fracture. The complications are high in four part fractures and old age. Good surgical skills and surgeon’s experience are of utmost importance for successful operative treatment.
