| Popis: | Rupture of the flexor pollicis longus (FPL) and index flexor digitorum profundus (FDP2) tendons often occurs after locking plate fixation for distal radius fracture. This study aimed to determine the shortest tendon-radius distances of different hand positions. Fifty-nine hands of 30 healthy volunteers were studied. Distances between the FPL or FDP2 and distal radius were calculated in six wrist positions: 30° palmar flexion, neutral, 30° dorsiflexion, 60° dorsiflexion, maximum dorsiflexion, and 40° ulnar deviation with three finger positions (full extension and flexion of fingers, full flexion of the thumb or index finger, and full extension of the other four fingers). The shortest distance between the FPL or FDP2 and distal radius was noted. The shortest distance between the FPL and distal radius was during maximum wrist dorsiflexion with isolated thumb flexion. The distance between the FDP2 and distal radius was shortest with all-finger flexion in 30° wrist dorsiflexion. It is necessary to measure the distance between the FPL and distal radius in maximal wrist dorsiflexion with full flexion of the isolated thumb, as the shortest distance was observed with flexion of the isolated thumb. On the contrary, we recommend measuring the distance between the FDP2 and distal radius in 30° wrist dorsiflexion with flexion of all fingers. |
