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 humerus is one of the long bones of the arm. The distal, or bottom, end contributes to the elbow joint. The proximal, or top, end contributes to the shoulder joint. During a traumatic event, like a fall, any part of the humerus is susceptible to injury. Other bones, including the clavicle (collarbone) or scapula (shoulder blade) can also be injured.
