The radiographic evaluation of gamekeeper's thumb is described in an experimental study in nine cadaveric hands. After the application of radial stress at the metacarpophalangeal joint in the extended and abducted thumbs in an attempt to create defects in the ulnar collateral ligament, initial and stress radiography and arthrography were employed. In four cadavers a fracture of the proximal phalanx was noted; stress radiography revealed variability in joint stability. Arthrography outlined ulnar extravasation in six of the nine cadavers; surgical confirmation of a capsular tear was obtained following careful dissection in each of these six cadavers. It would appear that plain films, stress radiography, and arthrography complement each other in the diagnosis of gamekeeper's thumb.
在一项针对九具尸体手部的实验研究中，描述了对守林人拇指的影像学评估。在伸直并外展的拇指掌指关节处施加桡侧应力，试图造成尺侧副韧带损伤后，采用了初始和应力位X线摄影及关节造影。在四具尸体中发现近节指骨骨折；应力位X线摄影显示关节稳定性存在差异。关节造影显示九具尸体中有六具存在尺侧造影剂外渗；在这六具尸体中，经仔细解剖后均获得了关节囊撕裂的手术证实。平片、应力位X线摄影和关节造影在守林人拇指的诊断中似乎相互补充。
