With a clinical practice that spans the range of upper extremity pathology, I have advanced training and interest in the newest techniques for hand and wrist trauma, arthritis of the upper extremity, nerve compression syndromes including carpal tunnel, tumors around the hand and arm, and repetitive stress injuries. The trend is towards less invasive procedures to allow more rapid return to work, sports, and daily activities. Surgery is just one option; many of these diagnoses can be successfully managed without surgery with a coordinated approach including therapy, medications, and patient education. Even though my focus is on the upper extremity pathology, it is important to recognize that these problems commonly affect the whole patient - their work, recreational activities, and even simple daily tasks - and their treatment must be undertaken in that context. Dr. Guyette is rated as a Distinguished provider by MediFind in the treatment of Tenosynovitis. His top areas of expertise are Synovitis, Dupuytren Contracture, Trigger Thumb, Wrist Arthroscopy, and Trapeziectomy.
