Cement‐Augmented Screw Fixation with PHILOS Plating for Osteoporotic Proximal Humeral Fractures: An Observation of Mid‐ and Long‐Term Curative Efficacy

Objectives The mid‐ and long‐term clinical outcomes of cement‐augmented screws in the treatment of osteoporotic proximal humeral fractures have rarely been reported. The aim of this study was to observe the mid‐ and long‐term efficacy of combined cement‐augmented screw fixation and PHILOS plating in the treatment of osteoporotic fractures of the proximal humerus. Methods This study retrospectively analyzed data from 19 patients with osteoporotic fractures of the proximal humerus who had undergone internal fixation at the Guizhou Provincial People's Hospital from February 2017 to May 2021. The cohort was comprised of six males and 13 females, aged 75–87 (mean age: 82.52 ± 1.24) years. According to the Neer classification, three, 12, and four patients had two‐part, three‐part, and four‐part fractures, respectively. All patients were treated with open reduction internal fixation with cement‐augmented screws and PHILOS plating. Time until fracture healing was recorded postoperatively. Patients were observed for postoperative complications, including humeral head necrosis, loosening or breaking of the augmented screws, screw perforation of the humeral head, and varus fracture displacement. Visual analog scale and Constant scores of the shoulder joint were compared 1, 3, 6, and 12 months after surgery. Scores at the most recent follow‐up were used to evaluate shoulder joint function. Measured data conforming to a normal distribution were expressed as mean ± SD. Analysis of variance or rank sum tests were used for intergroup comparisons. A value of p
