  1. The Effects of Edema & Self Adhesive Wrap on the Work of Flexion in a Cadaveric Hand Samuel D Buonocore MD

  2. Purpose: • To determine if the application of self adhesive wraps increase the work of flexion when hand therapy is initiated in edematous fingers.

  3. Introduction: • Forces generated in a repaired tendon are likely to be greater given the presence of edema, joint stiffness, muscle contracture, and the presence of the suture material within the tendon. • Early active protocols are often started within 24 hours of surgery and because edema can be significant 48 hours postoperatively, it is a common clinical scenario for hand therapy to be initiated in edematous digits. • To address this problem, self-adherent wraps are used in the postoperative period to try to eliminate edema. This study aims to determine if the presence of self-adherent wraps increase the work of flexion during early motion protocols.

  4. Materials and Methods: • A single fresh-frozen cadaveric hand with the distal 1/3 of the forearm intact was obtained. Flexor digitorum profundus tendons & flexor pollicis longus tendons were identified and dissected in the forearm, • Excursion of the flexor tendons for each of the digits was measured, the hand was then placed in a tensile testing machine, force excursion curves were generated for various clinical scenarios, including varying amounts of edema and the presence of two types of self adherent wraps. • Work of flexion (WOF) was calculated from the force excursion curves.

  5. Results: • Statistically significant increases in the WOF were noted for each of the clinical scenarios simulated, compared to the fingers baseline values for the WOF. • The increase in the WOF noted after the application of self adherent wraps was greater than the increase noted for moderate edema. • The effects on WOF were additive when both edema and self adherent wraps were present. The results were consistent among all 5 fingers tested.

  6. Conclusion: • Both the presence of edema and self adherent wraps increases the work of flexion in fingers in this cadaveric model. • Therapists and surgeons should be aware of the potential for increased stress placed on tendons when early motion protocols are initiated in these situations. • We recommend the removal of self adherent wraps before the therapy session begins, this is especially true if edema is also present.
