The flexor digitorum profundus (FDP) tendon may retract after avulsion or division in Zone 1. When treatment has been delayed, the oedematous tendon can be too swollen to pass freely through the A4 pulley. We present a new technique for dealing with this situation which depends on the "double-barrelled" nature of the distal part of the FDP tendon. One half of the tendon is excised longitudinally and the remaining "demi-tendon" is passed through the intact A4 pulley to allow tendon repair or re-attachment. This technique has been used in six cases in which passage of the FDP tendon through the A4 pulley would otherwise have been impossible.
指深屈肌腱（FDP）在1区发生撕脱或离断后可能会回缩。当治疗延迟时，水肿的肌腱可能会肿胀得无法自由通过A4滑车。我们提出一种处理这种情况的新技术，该技术基于FDP肌腱远端的“双筒”特性。将肌腱的一半纵向切除，剩余的“半腱”穿过完整的A4滑车，以进行肌腱修复或重新附着。该技术已应用于6例FDP肌腱原本无法通过A4滑车的病例。
