Intramedullary nail system for the proximal humerus
Description
The blood supply to the capitellar fragments provided by the fine branches of the circumflex humeral artery can be damaged by surface compression, e.g. by a T-plate, and by the constricting effect of cerclage wires. Since the interlocking screws, as peripheral load-bearing fixation elements, penetrate the tissue only at certain points, damage to the soft-tissue zone near the capitellum is minimized so that the blood supply in the fractured capitellum is given a maximum chance of recovery.
