The significance of extensor tendon tethering and dorsal joint capsule tightening after injury to the hand.
This paper examines the clinical problem of extensor tendon tethering and/or dorsal joint capsule tightening secondary to hand injury. One hundred and forty-one patients were examined 13 to 51 months after hand injuries of varying severity. Fifty-six patients (40%) had suffered simple and eighty-five patients (60%) complex injuries. Seventy-four (52%) of the 141 patients had no extensor tendon tethering and/or dorsal joint capsule tightening. In 30 (21%), the extensor tendon tethering and/or dorsal joint capsule tightening was considered to be "obvious" in that it was easily seen on examination using various commonly used clinical tests of finger flexion and extension. In 37 (26%), the extensor tendon tethering and/or dorsal joint capsule tightening was considered to be of "lesser degree" because it was only evident on application of specific tests which are described in this paper. Of the 37, 21 (56%) described themselves as being unable to make a "proper" fist with the injured hand, 33 (89%) had pain or discomfort on the dorsum of the injured hand and/or fingers on gripping (P < 0.01) and 25 (70%) had weakness of power of gripping (P < 0.01). Thirty-two (87%) complained of functional problems at work, with activities of daily living or with the pursuit of their hobbies.
