Abstract:
Objective:To compare a novel kind of anatomical locking plate versus proximal humeral internal locking system (PHILOS) in the treatment of proximal humerus fractures.Methods:A retrospective study was performed in the 35 patients with proximal humerus fracture who had been operatively treated at Department of Orthopedics, The Third Hospital of Peking University from January 2020 to June 2021. They were 13 males and 22 females, aged from 24 to 83 years (average, 56.7 years). Of them, 14 were fixated by the novel anatomical locking plate and 21 by PHILOS. The 2 groups were compared in terms of gender, age, fracture type, operation time, intraoperative blood loss, hospital stay, University of California (UCLA) shoulder scores and Disability of Arm Shoulder and Hand (DASH) scores for the upper limb dysfunction at one month after operation and at the last follow-up, and postoperative complications.Results:There was no significant difference in the preoperative general data between the novel plate group and the PHILOS group, showing comparability between them ( P>0.05). All the patients were followed up for 6 to 21 months (mean, 11.3 months). In the novel anatomical plate group, the operation time was (83.9±29.2) min, the intraoperative blood loss was (36.4±27.1) mL, the hospital stay was (2.3±1.1) d, the UCLA score and DASH score at one month after operation were (20.1±4.7) points and (55.5±19.1) points, the UCLA score and DASH score at the last follow-up were (28.5±4.6) points and (25.1±24.4) points, respectively; 2 patients developed complications after operation. In the PHILOS group, the operation time was (85.0±38.8) min, the intraoperative blood loss was (62.9±46.8) mL, the hospital stay was (2.4±0.9) d, the UCLA score and DASH score at one month after operation were (21.0±3.8) points and (49.6±23.7) points, and the UCLA score and DASH score at the last follow-up were (28.0±5.1) points and (19.1±17.3) points, respectively; 3 patients developed complications after operation. There was no significant difference in all the above items between the 2 groups (all P>0.05). Conclusion:In the treatment of proximal humerus fractures, the novel anatomical locking plate is a feasible internal fixator because it is comparable to PHILOS in fine efficacy, good fracture healing, and satisfactory functional recovery of the shoulder joint.
