Gliding function following flexor-tendon injury. A biomechanical study of rat tendon function
JM Lane, J Black and FW Bora
Gliding function of flexor tendons one hour to eight weeks after a standard
injury was studied in rat digits by determining terminal force of flexion,
tendon excursion, and work of flexion using a tensile testing machine. A
rapid decrease in gliding occurred within hours of injury, indicating that
the postoperative hematoma and edema restrict gliding long before
collagenous adhesions are synthesized. The improvement in gliding function
with time implies that fibrous adhesions can be remodeled. Surgical methods
and therapeutic agents, therefore, should be directed toward limiting early
tissue injury and seeking ways to enhance the late remodeling of fibrous
peritendinous adhesions along functional lines.
