Functional outcome after management of displaced proximal humerus fractures using angle-stable plates: A prospective study

Abstract

Background: Management of three- and four-part fractures proximal humerus is a surgical challenge. Plate and screw fixation of these fractures is a viable treatment option. The aim of the present study is to analyze the clinical results after proximal humerus fracture fixation using angle-stable implants. Materials and Methods: Forty-eight patients (48 fractures) of the proximal humerus (three and four part, Neer classification) were treated at our institute by proximal angle-stable plates. Patients between 27 and 85 years presented to us during the study (Mean = 51.104 years, range = 27–85 years) over a 1-year and were operated by open reduction and internal fixation with angle-stable plates. Patients were followed up at 3, 6, and 9 months and evaluated using the Constant-Murley and Disabilities of the Arm, Shoulder, and Hand (DASH) scores. Results: The mean follow-up period was 24 months (8–60 months). Fractures united at an average of 12 weeks (range 8–16 weeks) with a mean follow-up of 1.5 years (10–18 months). The mean Constant-Murley and mean DASH scores at final follow-up visit were 67.438 and 17.154, respectively. Conclusion: Despite some complications, the locking plate system is quite efficient in the management of three- and four-part fractures proximal humerus.
