Flexor Tenolysis


  • The flexor tendons are stuck down in the tunnel system causing restriction in range of movement.


  • Adhesions have formed between the tendon and surrounding pulley system. This usually occurs after tendon lacerations have been repaired for significant injury to the fingers.


  • There is a lack of active flexion, re the patients arm muscle power.
  • The fingers can usually be passively flexed, by the other arm, or by the hand therapist.


  • Hand therapy – work at trying to maximize gains of active flexion in keeping the finger joints supple.
  • If no progress is made after three to six months, surgery is recommended.
  • Surgery – GA – day surgery
    • Opening of the finger via a volar approach
    • Division of adhesions by surgical dissection
    • Early hand therapy post operatively to maximize surgical gains.

Potential Complications

  • Infection, haematoma, neurovascular injury, further stiffening and adhesions.

Post Op Care

  • Light dressings and then to hand therapy to push active and passive range of motion for up to three months.
