Arthroscopic Glenoid Augmentation for Glenoid Bone Loss
The shoulder joint is composed of three bones, the scapula (shoulder blade), the clavicle (collarbone) and the humerus (upper arm bone). The humeral head rests in the shallow socket of the scapula, known as the glenoid. The glenoid bone can become damaged and develop bone loss, typically from recurrent shoulder instability. Patients who have glenoid bone loss associated with recurrent shoulder instability may become candidates for glenoid reconstructive surgery, otherwise known as an arthroscopic glenoid augmentation. Greater Los Angeles, California area shoulder surgeon, Dr. Mark Getelman with offices in Van Nuys and Thousand Oaks specializes in diagnosing and treating shoulder instability connected with glenoid bone loss.
Shoulder instability occurs when the humeral head is forced out of the shoulder socket. This generally occurs from overuse or a traumatic event. Patients suffering from shoulder instability experience chronic pain and repeated shoulder dislocations which often results in varying levels of anterior-inferior glenoid bone loss.
Once glenoid bone loss is diagnosed, surgical correction must be performed. Dr. Getelman specializes in various arthroscopic glenoid augmentation procedures, all designed to address glenoid bone loss. The amount of bone loss necessary to consider glenoid surgery varies, but many orthopedic specialists agree bone loss greater than 20-25 percent will require some form of augmentation.
Several types of grafts can be used for arthroscopic glenoid augmentation to rebuild bone loss and reconstruct the glenoid. These grafts include:
- Distal clavicle autograft
- Iliac crest autograft
- Distal tibia allograft
In autograft cases, a patient’s own tissue is harvested, either from the clavicle or the iliac crest (largest bone in the hip), and used to reconstruct the area of glenoid bone loss. In distal tibia allograft cases, a portion of a donor’s tibia is harvested and used to perform the reconstruction.
Dr. Getelman will explain the different graft options in great detail with each patient requiring an arthroscopic glenoid reconstructive surgery.
