Previous studies showed canine digital-flexor-tendon healing by cellular activity of surrounding tissues, not by intrinsic tenoblastic activity. Adhesions occur at wound sites and points of tendon trauma; their density and severity reflect degree of tendon trauma. In the present study of 70 tendons, digital-sheath excision did not adversely affect tendon union or function, since new gliding sheaths formed. However, total sublimis tendon excision after profundus repair resulted in dense adhesions between profundus tendons and the osseous floor of the digital canals. Subtotal sublimis excision preserved the floors of the canals, and no adverse adhesions resulted. Avoidance of tendon trauma and preservation of the anatomic integrity of normal contiguous structures are essential for successful tendon surgery. |
