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.
The most common cause of nerve endings to the  shoulder results from a proximal humerus fracture. Running  circumferential to the proximal end of the humerus is the axillary â¦  nerve. Injury to the humerus such as fractures or subluxation can  directly injure the axillary nerve resulting in possible sensation  loss or muscle weakness around the deltoid, teres minor and triceps  muscle.
