梯形骨折和钩骨骨折延迟愈合的情况很少见，也很难治疗。骨折碎片可包括具有腕伸肌插入物的邻近掌骨。这两例分别发生在第2掌骨和第5掌骨根部直接撞击后。当仅使用石膏固定时，桡侧腕长伸肌和尺侧腕长伸肌是可能延迟骨愈合的变形力。当伴有掌骨关节内骨折及其肌腱附着物时，即使是最小移位的梯形或钩状骨折，也主张早期内固定。
Delayed union of fractures of the trapezoid and body of the hamate are rare and difficult to treat. The fracture fragments may include the neighboring metacarpals with the insertions of the wrist extensors. These two cases occurred after direct blows to the bases of the 2nd and 5th metacarpals, respectively. The extensor carpi radialis longus and extensor carpi ulnaris are deforming forces that may delay osseous union when cast immobilization alone is used. Early internal fixation is advocated for even minimally displaced fractures of the trapezoid or hamate when accompanied by intra-articular fragments of metacarpal with their tendinous insertions.
