As a fellowship-trained and board-certified orthopedic surgeon specializing in upper extremity and joint replacement surgery, Dr. Bruce Thoma’s expertise includes the diagnosis and treatment of injuries and conditions of the elbow, hand, shoulder, and knee. Dr. Thoma offers knee and shoulder injections, total knee and shoulder replacements, and arthroscopy of the knee and shoulder to help his patients return to normal function. 

Dr. Thoma’s formative education took place at St. Mary of the Lake Grade School and Andrean High School, after which, he earned his Bachelor of Arts degree from Indiana University in Bloomington, Indiana. The next four years were spent on a U.S. Navy destroyer during the Vietnam War. After returning home, he was eager to become a doctor and was accepted to the Indiana University School of Medicine in Indianapolis, Indiana. He completed his flexible internship at Mercy Health Saint Mary’s Campus in Grand Rapids, Michigan, and his orthopedic residency at Lutheran Hospital in Fort Wayne, Indiana. He then underwent specialized fellowship training at the Rancho Los Amigos National Rehabilitation Center in Downey, California, before going to work at the Valparaiso Orthopedic Clinic in 1987, which has grown into the Lakeshore Bone & Joint Institute of today, a complex and far-reaching enterprise.

Throughout his years of practice, Dr. Thoma has relied on the support of the talented and giving doctors and staff at Lakeshore Bone & Joint Institute as well as his wife, three children, and his extended family. He enjoys sprint triathlons and ice hockey as well as World War II history.

Dr. Thoma sees patients at our Chesterton and Valparaiso – Cumberland offices.
