Washington Nationals right-handed pitcher John Patterson had successful exploratory surgery performed this morning on his right forearm by Nationals Orthopedist Dr. Ben Shaffer and Nationals hand consultant Dr. Richard Barth at Sibley Hospital in Washington, D.C.
During the 75-minute procedure, Patterson's lacertus fibrosis was released and the median nerve was explored and decompressed. Several areas of constriction within the nerve were released, thus leaving the nerve healthy and free of compression.
Patterson, 28, will be in a splint for one week, at which time he will begin range of motion and strength exercises. He is expected to be out approximately 4-6 weeks.
