Extensor tendon: Anatomy, injury, and reconstruction

Although seemingly simple in its anatomy and function, the extensor mechani sm of the hand is actually a complex set of interlinked muscles, tendons, a nd ligaments. A thorough understanding of the extensor anatomy is required to understand the consequences of injury at various levels. Reconstructive options must restore normal function. Whereas primary repair of anatomic st ructures is frequently possible in acute injury, it is rarely possible in c hronic situations. Technically exacting procedures may be necessary to rest ore function.
