Brandon Clark, D.O.

Trauma, Arthroplasty Surgery of the Hip and Knee

Dr. Brandon Clark is a fellowship trained orthopaedic surgeon specializing in Orthopaedic Trauma and Adult Post-traumatic Reconstruction with the Arthritis and Fracture Care Center at NAO. Considered a specialist in Orthopaedic Trauma, Dr. Clark helps those with multiple orthopaedic injuries, fractures of the pelvis and hip, and complex fractures around major joints. Dr. Clark and his partner, Tim Bonatus, D.O., are the only fellowship-trained Orthopaedic Trauma surgeons north of Phoenix. Their life-saving skills are performed at the Level 1 Trauma Center in Flagstaff and lives are being saved for trauma victims daily. Together, they provide a tremendous service in this region.

Dr. Clark is also a member of the Arthritis and Fracture Care Center team, located at the Summit Center. Here, he provides a wide range of treatment options for patients with hip and knee arthritis, including non-surgical interventions, as well as total joint replacements. He also provides surgical repair and reconstruction of broken bones that have failed to heal or have healed in a poor position. Dr. Clark is versatile at the most advanced surgical techniques, including the Anterior Hip Approach, a tissue-sparing alternative to traditional hip replacement, providing the potential for less pain, faster recovery and improved mobility because the muscle tissues are spared during the surgery.

Originally from Craig, Colo., Dr. Clark obtained a bachelor’s of science from Oklahoma State University (OSU) and a master’s of science in Physiology from the University of Oklahoma. He later returned to OSU to obtain his medical degree then completed his residency in Orthopaedic Surgery at Bone & Joint Hospital at St. Anthony, Oklahoma City. He rounded out his formal training with his completion of an orthopaedic trauma fellowship at the prestigious University of Pittsburgh Medical Center, which is recognized nationally as a top-five trauma hospital and training facility.
