Small bone suture anchors offer a reliable alternative for hand and wrist reconstructive surgery. These anchors demonstrate comparable strength to traditional methods with improved stiffness and surgical efficiency.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Hand and Wrist Reconstruction

Background:

  • Small bone suture anchors are emerging tools for hand and wrist reconstructive surgery.
  • Evaluating their efficacy compared to established techniques is crucial.

Purpose of the Study:

  • To compare the biomechanical properties and clinical outcomes of small bone suture anchors versus the Bunnell technique for flexor digitorum profundus (FDP) tendon reinsertion.
  • To assess the feasibility and reliability of bone anchors in clinical hand and wrist repairs.

Main Methods:

  • A paired cadaveric study (16 fingers) compared Acufex 2 mm anchors with the Bunnell technique for FDP reinsertion.
  • Load-to-failure and stiffness were measured.
  • A prospective clinical study enrolled 19 patients undergoing hand or wrist tendon/ligament repair with bone anchors.

Main Results:

  • No significant difference in load-to-failure (approx. 40 Newtons) between anchors and the Bunnell technique.
  • Bone anchor repairs exhibited significantly greater mean stiffness.
  • Clinical follow-up (average 24 months) showed stable repairs, with anchors being simple to insert and reducing surgical time.

Conclusions:

  • Small bone suture anchors provide reliable and biomechanically sound repairs for hand and wrist tendon and ligament injuries.
  • They offer advantages in surgical efficiency and stiffness compared to the traditional Bunnell technique.
  • Bone anchors represent a viable and effective option in reconstructive surgery of the hand and wrist.
