LEWISTON — “Surgical Treatment of Shoulder Problems” is the subject of a special presentation set for Tuesday, March 12, at Central Maine Medical Center.

Orthopaedic surgeon Matt Bush, MD, will discuss shoulder replacement, reverse shoulder replacement and shoulder arthroscopy, all surgical options for repairing shoulder problems resulting from rheumatoid arthritis or injury.

Shoulder replacement is a surgical procedure in which all or part of the shoulder joint is replaced by a prosthetic implant. The procedure is usually done to relieve arthritis pain or fix severe joint damage.

Bush will talk about the two primary methods for shoulder replacement: total shoulder replacement and reverse shoulder replacement.

Total shoulder replacement involves a replacement of the ball and socket joint. A metal ball replaces the head of the upper arm bone and a plastic socket replaces the cartilage on the cavity.

A reverse shoulder replacement involves the insertion of a metal ball section to the ball of the joint and a socket section being added to the upper arm bone. A reverse shoulder procedure, which is used to treat those with severe damage or arthritis involving the shoulder joint, allows the arm to be moved by different muscles.

Bush will also discuss shoulder arthroscopy, a surgical approach that uses a tiny camera and surgical tools to examine and repair the tissues inside or around the shoulder joint. Arthroscopic surgery can be used to repair a damaged rotator cuff, relieve impingement syndrome and correct shoulder instability.

A graduate of Dartmouth College in Hanover, N.H., Bush earned his medical degree from Columbia University College of Physicians and Surgeons in New York City. He served an orthopaedic surgery residency at Hospital for Special Surgery in New York City and at Rhode Island Hospital, Providence, R.I. He completed a hand and upper extremity fellowship at Wake Forest University in Winston Salem, N.C.

Bush is certified by the American Board of Orthopaedic Surgery. He practices with Central Maine Orthopaedics at 690 Minot Ave., Suite 1, Auburn.

The presentation is being sponsored by the Orthopaedic Institute of Central Maine, a partnership of Central Maine Medical Center and Central Maine Orthopaedics.

The presentation will be offered from 6 to 7 p.m. March 12 in the Chairmen’s Rooms on the lower level of the 12 High Street medical office building.
