The TCO Foot and Ankle Fellowship program offers advanced subspecialty training in foot and ankle orthopaedics in a high-volume private practice. The Fellow can expect exposure to all aspects of foot and ankle orthopaedics with a particular focus on ankle replacement and arthrodesis, hindfoot and forefoot reconstruction, sports injuries, and trauma. The Fellow will be expected to: develop knowledge and skills to cultivate an individual practice; develop the knowledge and skills necessary to provide complete orthopaedic foot and ankle care for persons of all ages; participate as a member of a team that includes physicians, rehabilitation specialists, and prosthetists and orthotists; and participate in a publishable-quality research project. This fellowship supports professional growth through regularly scheduled didactic lectures, monthly journal club and research meetings, industry labs, and participation in AOFAS Winter and Annual meetings.
The fellow will rotate for a total of three months (two six-week rotations) with each of the four attendings (Dr. Paul Cammack, Dr. William Engasser, Dr. Jeffrey Seybold, and Dr. John Tanner). The fellow will be expected to work with another team if their attending is away for any extended period of time during the scheduled rotation. The schedule will be adjusted as best as possible to maximize time with all four attendings and cover the recommended list of procedures.
TCO Foot & Ankle Fellowship has achieved AOFAS Fellowship Accreditation.
