The button-over-nail technique for Zone I flexor tendon injuries.
The "button over the nail" is the most commonly used technique in order to re-insert the flexor digitorum profundus tendon into the distal phalanx in the management of Zone 1 injuries. Recent evidence in the literature has highlighted an associated morbidity with the technique. In this study, 37 patients were identified that had been treated using the "button technique", for which outcome data is collected by hand therapists as part of a prospective flexor tendon injury audit. Retrospective case note review was performed to determine incidence of post-operative surgical complications.   There were limited complications with the use of the "button technique" overall. However, functional outcome when compared to other studies are relatively poor with mean range of motion at the distal interphalangeal joint being 37.5 degrees. The authors would recommend any decision to change technique for the management of these injuries should consider functional outcome in the presence of a low surgical complication rate.
