Extensor Tendon Repair Technique
- Zone 1 (DIP joint):running 5-0 Prolene suture supplemented by a transarticular Kirschner
wire in full extension for 6 week
- Zone 2 (middle phalanx): Running 5-0 suture near cut edge of tendon, reinforced with “basket-weave” or “Chinese
fingertrap” type of cross-stitch on dorsal surface of the tendon
- Zones 3 through 5 in fingers, and zones 2 and 3 in thumb: Modified Kessler core 4-0 suture, reinforced with 5-0 cross-stitch on the dorsal surface
- Zones 6 and 7: Modified Kessler core 4-0 suture, reinforced with 5-0 cross-stitch run around the entire circumference of the
tendon
Extensor Tendon Repair Complications
Extensor Tendon Repair Follow-up care
- Zones 1 and 2: 6 weeks of immobilization with either splint or Kirschner wire fixation of the DIP joint
- Zones 3 through 5: splint with the wrist in 40 degrees of extension, slight flexion at the MP joint, and extension at the PIP joints for 4 weeks.
- Zones 6 and 7: splint with the wrist in 40 degrees of extension, slight flexion at the MP joint, and extension at the PIP joints for 4 weeks. Allow full active motion at the IP joints.
- Consider Dynamic splinting (passive joint extension with a dynamic outrigger device, with
flexion limited by palmar splint), Controlled active mobilization (active joint extension, limiting joint flexion with a palmar splint). Dynamic provides better short term outcomes but is equivalent to static splinting at 6 months. (Mowlavi A, Plast Reconstr Surg2005; 115:482-487)
Extensor Tendon Repair Outcomes
- Patients without associated injury = 64% achieved good or excellent results; With associated injury =45% good or excellent results. More fingers loose ability to flex fully than ability to extend fully. Injuries in zones 1 through 4 have a worse outcome than injuries in the more proximal zones.
