The aim of the present study was to evaluate the functional outcome, benefits and complications of open reduction and internal fixation of displaced proximal humerus fractures with proximal humerus locking plate.
We studied the functional outcome of 40 patients aged between 15 to 65 years from September 2013 to February 2015, who had displaced proximal humerus fracture and underwent PHILOS plate fixation for the same. Fractures were classified according to NEER’s and AO classification. Patients were followed up for a minimum period of 1 year. Functional outcomes and shoulder range of movement were assessed based on the Constant and Murley scoring system.
Patients were followed up for 12 months. All fractures healed satisfactorily; 12 weeks (27.5%) was the most common union time (radiological finding) in the study population followed by 8 weeks (22.5%) and 10 weeks (20%). Avascular necrosis was noted in 1 patient, mild infection in 2 patients and stiffness in 2 patients. The mean Constant score at 6 weeks was 40.39, at 12 weeks was 59.24, at 6 months was 73.88 and at one year was 75.62. Constant score continues to improve till 1 year.
Proximal humerus locking plate gives a reliable, stable fixation for fractures of proximal humerus with a good radiological union and good functional outcome.
