Shoulder & Elbow Surgical Education

The information contained below is designed to provide patients and physical therapists with basic information on common surgical procedures. This service should supplement the information provided at your patient consultation office visit.


We employ a team approach to the treatment of disorders involving the shoulder and elbow. Lori Sharp is a board certified physician’s assistant who supports the team by seeing patients in the office as well as by assisting in the operating room and helping perform research activities. She is a native of the Knoxville area and has extensive knowledge of shoulder and elbow disorders. Dr. G. Brian Holloway and Dr. Edwin E. Spencer Jr. are board certified orthopaedic surgeons and specialize in all areas of shoulder and elbow surgery. Dr. Holloway attended Temple Medical School, graduated from a residency program at Akron General Orthopaedic, and performed a shoulder and elbow fellowship at the University of Pennsylvania. Dr. Spencer graduated from Duke Medical School and an orthopaedic residency program at the University of Michigan before performing a shoulder and elbow fellowship at the Cleveland Clinic. He has a strong interest in research and has published multiple articles in leading orthopaedic journals. Both physicians are involved in teaching at a national level and have been selected to be instructors at the national Orthopaedic Learning Center.

We at the Center specialize in all forms of shoulder surgery—from arthroscopic surgery such as rotator cuff repairs, to shoulder replacement, including total shoulder replacement. We also perform a new kind of procedure termed a reverse total shoulder replacement. Though a limited number of patients would need such a procedure, very few surgeons around the country are qualified to perform this surgery. We also perform complex operations such as tendon transfers and reconstructions.

Dr. Spencer and Dr. Robert Ivy specialize in elbow surgery. This includes tendon and ligament repair and reconstruction, such as the Tommy John procedure. We also perform elbow replacements and revisions as well as elbow arthroscopy.

All upper extremity fractures and dislocations are treated with both reconstruction and replacement.

Our group is actively involved in research at the local and national level. This includes biomechanical and clinical studies. A patient’s permission must be obtained prior to inclusion in any study. Patient participation is certainly encouraged to advance the treatment of shoulder and elbow disorders.
