Rotator Cuff Tear Repair Surgery

Overview of Rotator Cuff Tear Repair Surgery

The rotator cuff is a common source of pain in the shoulder. It refers to a group of four muscles and tendons that attach to the head of the humerus and stabilizes the shoulder as it moves in space. The most commonly affected tendon is the supraspinatus tendon.  Issues with the rotator cuff commonly cause problems with overhead activity, pain with sleeping on the shoulder, and moving the shoulder in certain motions.  If torn, the rotator cuff can cause progressive pain and disability in the shoulder.  Unfortunately, the rotator cuff has poor healing potential on its own and often requires surgical repair in many cases.

Biceps Tear or Injury

Introduction to Biceps Tears or Injuries

The biceps muscle goes from the shoulder to the elbow on the front of the arm. Two separate tendons connect the upper part of the biceps muscle to the shoulder, the long head tendon and the short head tendon.  The long head of the biceps connects the biceps muscle to the top of the shoulder socket, the glenoid.  The long head of the biceps tendon runs within the bicipital groove.   The short head of the biceps connects on the corocoid process of the scapula.  The lower biceps tendon is called the distal biceps tendon and it attaches to the radial tuberosity in the forearm.  The biceps is most commonly injured at the long head and more rarely it can be injured at the distal biceps tendon.  Depending on where it is injured and the finding depends on how the injury needs to be treated.

Shoulder Dislocation & Instability

Introduction to Shoulder Dislocation and Instability

The shoulder joint consists of the rounded top of the bone in the upper arm (humerus), which fits into the socket (glenoid) — the cup-shaped outer part of the shoulder blade.  When the top of the humerus moves out of its usual location in the shoulder joint, the shoulder is said to be dislocated.

Shoulder dislocations can occur after a traumatic event or can be atraumatic in people who are loose jointed.  In a dislocation event sometimes the structures around the shoulder can be damaged and can cause labral tears or rotator cuff tears.  Proper treatment is necessary to prevent recurrent instability of the shoulder joint which can cause continued dislocations and progressive damage if not treated appropriately.
