They’re a very important muscle group that’s located where your upper arm meets your torso. Your deltoids are one of the most complex muscle groups in your body, and they’re made to move.

A forceful injury can tear or rupture the bicep or tricep tendons. Injuries to the upper arm muscles and tendons are most common in men 30-50, but women also may experience them.

An individual typically wears their arm in a sling to keep it still while the tendon heals. This may vary depending on the surgical procedure and the severity of the tear.
