Titin is a giant protein responsible for muscle elasticity and provides a scaffold for several sarcomeric proteins, including the novel titin-binding protein MURF-1, which binds near the titin M-line region.
ORIF Surgery for Proximal Humerus Fracture. This surgical procedure repairs a break in the proximal end of the humerus. ORIF stands for Open Reduction Internal Fixation. During this procedure, an incision will be made and a metal plate will be attached to the humerus to hold the bone in place while it heals. Preparation.
Healing of a mid-shaft humerus fracture takes several months but often exercises to improve the mobility of the shoulder and elbow joints are initiated much sooner. The two complications often seen are injuries to the radial nerve and nonunion of the fracture. Injuries to the radial nerve occur because this important nerve tightly wraps around the middle of the humerus. The radial nerve can be injured at the time of the fracture or during treatment of the fracture.
