Wide Awake Flexor Tendon Repair in the Finger

Wide awake flexor tendon repair means no tourniquet and no sedation tendon repair under pure local lidocaine and epinephrine finger and hand anesthesia. The 5 main advantages of doing the repair this way in the unsedated patient are as follows: (1) fewer postoperative ruptures happen because intraoperative testing of the tendon repair reveals gaps in 7% of cases that are repaired before skin closure.1 (2) These repairs get less tenolysis because intraoperative testing of the repair guides the surgeon to vent pulleys that impede full flexion or extension of the finger.2 (3) Surgeons educate the lucid patient during the surgery, so he understands how to avoid rupture and getting stuck.3 (4) Intraoperative flexor tendon repair testing guides the surgeon in the decision to maintain a superficialis repair or resect a superficialis slip.4 (5) Seeing full active flexion and extension with no gap during the surgery empowers the surgeon to allow up to half a fist of true active postoperative flexion (not place and hold) 3 to 5 days after surgery.5 LOCAL ANESTHESIA Inject lidocaine with epinephrine (buffered 10:1 with 8.4% bicarbonate) everywhere you plan to dissect. Inject slowly from proximal to distal to decrease injection pain (See Video 1, Supplemental Digital Content 1, which displays a preoperative patient and local anesthetic injection.

Wait 30 minutes or more after the last injection to give time for maximal epinephrine vasoconstriction in the finger. OPERATIVE TIPS See Videos 2 to 4, Supplemental Digital Content 2, which demonstrates dissecting the skin flaps and exposing the sheath.

See video, Supplemental Digital Content 3, which demonstrates how to retrieve tendon ends.

See video, Supplemental Digital Content 4, which demonstrates how to suture the tendon and intraoperative patient education.

Repeatedly, test full active patient flexion and extension of the finger after each core and epitenon suture to make sure that there is no gap and that the repair fits through the pulleys. Repair any gaps and vent pulleys as required to get a full range of motion before skin closure. This is like testing blood flow in a vascular anastomosis to ensure function before skin closure. Have the patients extend the finger if you feel them pull against you as you retrieve the tendon. Extension generates reflex relaxation of flexor muscles. You do not need cautery. Bleeding stops by the time you sew back the skin flaps to expose the sheath. Surgeons can repair tendons in minor procedure rooms outside the main operating room in daytime hours. Involve hand therapists in patient teaching during surgery. POSTOPERATIVE THERAPY See Video 5, Supplemental Digital Content 5, which displays post operative therapy.

See video, Supplemental Digital Content 3, which demonstrates how the surgeon gets the patient to extend the finger to relax the flexor tendon and let it come distally in the sheath by pushing it with Adson forceps through sheathotomies.

Immobilize and elevate the hand until swelling, friction, and work of flexion is gone (3–5 days). Initiate up to half a fist of true active movement (not place and hold).
