Abstract
An in vivo experimental study was performed on the flexor profundus tendons of adult canines
to determine tensile strength differences between locking and grasping technique repairs
and to document the tensile strength using a passive mobilization protocol through
the first 21 days following surgery. Forty experimental third and fourth flexor tendons
of the right forepaws were lacerated and repaired with either of the 2 techniques.
The experimental tendons were harvested at days 3, 7, 14, and 21 and were biomechanically
tested. The third and fourth profundus tendons of the left forepaws were used as control
(day 0) tendons; they were lacerated and repaired with the locking or grasping techniques
at the time of harvest and also were biomechanically tested. The locking technique
statistically improved tensile strength values at days 0, 3, and 21. The tensile strength
decrease was minimal when using a passive mobilization protocol after surgery. (J
