Abstract
Background
The aim of this study was to evaluate clinical results and complication rate in patients with proximal humeral fracture treated with Anatomical Locking Plate System (A.L.P.S.) Proximal Humeral Plating System with smooth pegs.
Methods
Retrospective evaluation of 116 consecutive patients treated with A.L.P.S. Proximal Humeral Plating System. Shoulder function was evaluated by Constant score and disabilities of arm, shoulder and hand (DASH). Furthermore, European Quality of life 5 Dimensions (EQ-5D) and single shoulder value (SSV) were assessed. Fractures were classified according to Neer.
Results
Fifty-two patients were included with a mean follow-up of 49 months. Mean Constant score was 62.8. Mean DASH was 17, and the mean EQ-5D was 0.91. According to Neer classification 63% (n = 33) of the fractures were two-part, 31% (n = 16) three-part, and 6% (n = 3) four-part fractures. Peg penetration was registered in 13 cases (25%, n = 52). In total a reoperation rate of 23% (n = 12) and an overall complication rate of 37% (n = 19) were recorded.
Discussion/conclusion
Open reduction and plate fixation with the A.L.P.S. Proximal Humeral Plating System with smooth pegs provides a stable fixation with good clinical outcome and complication and reoperation rates in line with previous studies with plates using screws in the humeral head.
