52 hands have been dissected to check the anatomy and function of the extensor pollicis brevis. Various abnormalities were found: absence of the E.P.B. (two), insertion on the distal phalanx (four), absence of bony insertion on the base of the first phalanx and insertion on the extensor hood (36). In ten cases (in addition to the two with absence of E.P.B.), no function was elicited by pulling the tendon which inserted upon the extensor hood.
解剖了52只手以检查拇短伸肌的解剖结构和功能。发现了各种异常情况：拇短伸肌缺如（2例），止点在远节指骨（4例），在近节指骨基部无骨性止点且止点在伸肌帽上（36例）。在10例病例中（除了2例拇短伸肌缺如的病例外），牵拉止于伸肌帽的肌腱未引出功能。
