A taper broach is a surgical cutting instrument used in orthopedic and podiatric surgery to prepare the intramedullary canal of small bones, specifically the phalanges (toes) and metatarsals (long bones of the foot), for implant placement. It features a tapered, fluted design that progressively widens and shapes the canal to accommodate a tapered implant, such as a stemmed prosthesis or a screw.
