Although seemingly simple in its anatomy and function, the extensor mechanism of the hand is actually a complex set of interlinked muscles, tendons, and 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 structures is frequently possible in acute injury, it is rarely possible in chronic situations. Technically exacting procedures may be necessary to restore function.
尽管手部伸肌机制在解剖结构和功能上看似简单，但其实际上是一组由肌肉、肌腱和韧带相互连接而成的复杂结构。要了解不同层面损伤的后果，需要对手部伸肌的解剖结构有透彻的理解。重建方案必须恢复正常功能。虽然急性损伤时解剖结构的一期修复通常可行，但在慢性损伤情况下则很少能够实现。可能需要技术要求严格的手术来恢复功能。
