Extensor Tendon Injuries

Like flexor tendons, the extensor tendons are very close to the skin, and consequently highly susceptible to damage with cuts, lacerations and crush injuries. While the anatomy of the extensor system does not involve pulleys and other surrounding structures that restrict tendon motion, they are equally susceptible to scarring to surrounding tissue after injury. This is particularly true after a “combined injury” consisting of fracture, extensor tendon injury and nerve laceration. These, too, are complex injuries requiring meticulous surgical care and expert post-operative therapy.
