Where this comes from

Procedure volumes:CMS Medicare Physician & Other Practitioners, 2024. Fee-for-service claims only, so they exclude privately insured, Medicare Advantage and pediatric patients - volume is not comparable across practices with different patient mixes. These are billing records, not outcomes.

Training and practice: CMS Doctors and Clinicians list. A graduation year is when training finished, not years of orthopedic experience or a board certification. Affiliations come from Medicare enrollment and may be incomplete.

Registry details: NPPES. Subspecialties are self-reported at registration, not a board certification.

Credentials: Doctor of Medicine (MD)

An MD degree indicates completion of a medical doctorate program focused on allopathic medicine. MDs complete four years of medical school followed by residency training in their chosen specialty. Orthopedic surgery residencies typically last five years and include extensive training in surgical and non-surgical treatment of musculoskeletal conditions.
