“…Interconnections between the flexor pollicis longus (FPL) and the extensor pollicis longus (EPL) tendons and a duplicated FPL are observed frequently. 5 Absence or hypoplasia of the extrinsic extensors (EPL and extensor pollicis brevis) or flexors (FPL) requires an observant examination of the active movement at the MCP and interphalangeal joints. Type III hypoplasia is divided into subtypes IIIA with a stable CMC joint and IIIB with an unstable CMC joint, 2 which is a crucial differentiation for the treatment paradigm.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
