Summary

Free tendon grafts can restore function in fingers and thumbs when primary repair is not feasible due to delayed treatment or tendon damage. This method proved successful in a majority of patients, offering a viable solution for complex flexor tendon injuries.

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Reconstructive Surgery

Background:

  • Primary suture repair of flexor tendons is often inadvisable in cases of delayed treatment (weeks/months), tendon rupture with nonviable segments, failed primary repair, or infection.
  • Restoring continuity in profundus or flexor pollicis longus tendons is crucial for hand function.

Purpose of the Study:

  • To evaluate the efficacy of using free tendon grafts to bridge defects in adult flexor tendons when primary repair is not optimal.
  • To assess the functional outcomes of free tendon grafting for finger and thumb reconstruction.

Main Methods:

  • Free tendon grafts were utilized to bridge gaps in flexor tendons, specifically profundus and flexor pollicis longus tendons.
  • Patient selection criteria included intact flexor tendon within the digital sheath and adequate muscle function.

Main Results:

  • Satisfactory function was restored in 28 out of 37 treated fingers.
  • Satisfactory function was achieved in eight out of ten treated thumbs.

Conclusions:

  • Free tendon grafting is an effective method for restoring continuity and function in complex flexor tendon injuries where primary repair is contraindicated.
  • The success of this reconstructive procedure is contingent upon the condition of the remaining flexor tendon sheath and the motor muscle unit.
