Zone I Flexor Digitorum Profundus Repair: A Surgical Technique

Area of Science:

• Orthopedic Surgery
• Hand Surgery
• Tendon Repair

Background:

• Zone I flexor tendon injuries require robust repair techniques to restore function.
• Traditional methods may have limitations regarding fixation strength or potential complications.

Purpose of the Study:

• To describe a novel all-inside technique for zone I flexor tendon repair.
• To present a method combining suture anchor fixation with buried back-up fixation.

Main Methods:

• An all-inside technique utilizing suture anchors and transosseous tunnels for fixation.
• A dorsal counterincision for buried suture tie-off, avoiding suture buttons.
• Proposed anesthesia: wide awake; Incisions: midlateral; Exposures detailed.

Main Results:

• The described technique provides strong fixation for zone I flexor tendons.
• Allows for early active range of motion post-operatively.
• Avoids the need for a suture button, thus protecting the nail matrix.

Conclusions:

• This all-inside technique offers a strong and safe option for zone I flexor tendon repair.
• Facilitates early rehabilitation by permitting active range of motion.
• The technique is advantageous as it does not jeopardize the nail matrix.
