Mesovascularized island flexor tendon: new concepts and techniques for flexor tendon salvage surgery.
Hand surgeons have long sought ways of avoiding adhesions in flexor tendon repair. We report a new concept in tendon surgery--the use of flexor tendons with perfect mesotendon blood supply and an inherent gliding mechanism composed of the paratendon and the common carpal sheath to minimize adhesions during tendon healing. This technique, inspired by reversed ulnar island forearm transfers, makes use of the flexor superficialis of the ring finger, which is supplied by a vascular mesotendon emerging from the ulnar pedicle just before Guyon's canal, and ensures a perfect blood supply, a favorable environment for suturing, and, consequently, impressive digital excursion.
