The shoulder specialists at COMG offer state-of-the-art minimally invasive arthroscopic procedures for a range of shoulder disorders.

Rotator Cuff Tear Img

Rotator Cuff Tear

A rotator cuff is a group of tendons in the shoulder joint that provides support and enables a wide range of motion. A major injury to these tendons may result in rotator cuff tears. It is one of the most common causes of shoulder pain in middle-aged and older individuals

Shoulder Instability Img

Shoulder Instability

Shoulder instability is a chronic condition that causes frequent dislocation of the shoulder joint.

Labral Tear Img

Labral Tear

Traumatic injury to the shoulder or overuse of the shoulder (throwing, weightlifting) may cause the labrum to tear. In addition, aging may weaken the labrum leading to injury.

Shoulder Impingement Img

Shoulder Impingement

The shoulder is a ball-and-socket joint. The ball-shaped end of the upper arm bone (humerus) fits neatly into a socket, called the glenoid, which is part of the shoulder blade or scapula.

Shoulder Arthroscopy Img

Shoulder Arthroscopy

Shoulder arthroscopy is a minimally invasive diagnostic and surgical procedure for conditions and injuries involving the bones, cartilage, tendons, ligaments, and muscles of the shoulder joint.

Shoulder Labrum Reconstruction Img

Shoulder Labrum Reconstruction

Traumatic injury to the shoulder, overuse of the shoulder associated with excessive throwing or weightlifting can cause a labral tear. It may also result from a weakened labrum due to aging.

Rotator Cuff Repair Img

Rotator Cuff Repair

The rotator cuff is a group of 4 muscles in the shoulder joint including the supraspinatus, infraspinatus, teres minor, and subscapularis. These muscles originate in the scapula and attach to the head of the humerus through tendons. The rotator cuff forms a sleeve around the humeral head and glenoid cavity, providing stability to the shoulder joint while enabling a wide range of movements.

SLAP Repair Img

SLAP Repair

Repeated use of the shoulder while throwing or a fall onto the shoulder can result in a SLAP (superior labrum anterior and posterior) tear or injury.

Superior Capsular Reconstruction Img

Superior Capsular Reconstruction

Superior Capsular Reconstruction is a surgical procedure to repair massive, irreparable rotator cuff tears. The surgery involves reconstruction of the superior capsule of the shoulder joint using an autograft (tissue from the same person) or an allograft (tissue from a donor)

Arthroscopic Latarjet Procedure Img

Arthroscopic Latarjet Procedure

The Latarjet procedure is an advanced procedure to treat shoulder instability caused by lack of bony support in the shoulder joint.

Arthroscopic Bankart Repair Img

Arthroscopic Bankart Repair

Young people who have sustained a dislocation of the shoulder may experience a specific type of labral tear called a Bankart tear. The condition usually occurs during a shoulder injury.

Arthroscopic Subacromial Decompression Img

Arthroscopic Subacromial Decompression

Subacromial decompression is a surgical procedure performed for the treatment of a condition called shoulder impingement. In shoulder impingement, the degree of space between the rotator cuff tendon and shoulder blade is decreased due to irritation and swelling of the bursa or due to development of bone spurs.
