A Biomechanical Study of Double-row Suture-bridge and Double-screw Fixation Strength in Split-type Greater Tuberosity Fractures of the Humerus
Background: This study aimed to compare the fixation strength of double-row suture-bridge (DR) and double-screw (DS) fixation methods in treating split-type greater tuberosity fracture of the humerus.Methods: We established 24 fracture models of frozen pig shoulders with reserved supraspinatus, infraspinatus, and teres minor muscles. The specimens were randomly divided into two groups according to the fixation methods of double-row suture-bridge (group A) and double screws (group B).
