[Strength required for mobilization of reconstructed flexor tendons in the front paw of the dog]

Adhesions of tendons with surrounding tissue, especially in zone II, are frequent complication at the reconstruction of flexor tendons of the hand. Through knowing of biomechanical incidents between the reconstructed flexor tendon and the surrounding tissue we get significant data for post-operative procedures, and that improves the opportunity for obtaining good functional results. By successive loading of operated flexor digitorum profundus in the experimental animals - dogs, medium values of force necessary for mobilization of tendons obtained on 3. post-operative day are 0 = +/- 3.36 N, 5. day 0 = +/- 6.85 N, 10. day 0 = +/- 9.58 N and 15. day 0 = +/- 10.19 N. It can be concluded that peritendon adhesions occur between 3 and 5 post-operative day. In time, the adhesions get stronger and block the movements of the tendon, and growing force is necessary for their mobilization.
