Chicken Model

We report the effects of early and late ultrasound treatment protocols on healing of surgically lacerated zone 2 flexor tendons in a chicken model. Ultrasound was administered directly using a coupling gel. Treatment was shown to increase range of movement, to advance scar maturation and to decrease the amount of inflammatory infiltrate around the repair site. No adverse effects on tensile strength were noted in either group. Early (starting 7 days post-operatively) administration was more effective than late (starting 42 days post-operatively) administration in achieving these effects. These results suggest that ultrasound therapy may be of benefit in the early healing process of flexor tendon lacerations.

SummaryObjective: Even though equine multi-limb tendinopathy models have been reported, it is unknown if fore- and hindlimb tendon healing behave similarly. The aim of this study was to compare the healing process of surgically induced superficial digital flexor tendon (SDFT) core lesions of fore- and hindlimbs in horses.Methods: Tendon core lesions were surgically induced in the SDFT of both fore- and hindlimbs in eight horses. One randomly assigned forelimb and one randomly assigned hindlimb were injected with saline one and two weeks post-surgery. The healing process was monitored clinically and ultrasonographically. After 24 weeks, the tendons were harvested and biochemical, biomechanical and histological parameters were evaluated.Results: Twenty-four weeks post-surgery, the forelimb SDFT lesions had a significantly higher colour Doppler ultrasound vascularization score (p = 0.02) and glycosaminoglycan concentration (p = 0.04) and a significantly lower hydroxylysylpyridinoline content (p = 0.03).Clinical relevance: Our results indicate that fore- and hindlimb SDFT surgically induced lesions exhibit significant differences in several important parameters of tendon healing 24 weeks post-surgery. These differences create significant challenges in using all four limbs and accurately interpreting the results that one might generate. Therefore these findings do not support the use of four-limb models for study of tendon injury until the reasons for these differences are much better understood.

Flexor Digitorum

The purpose of this study was to examine the in vivo characteristics of the stainless-steel Teno Fix™ device used for flexor tendon repair. The common flexor digitorum superficialis tendon was transected in 16 dogs and repaired with the device. The animals were euthanized at 3, 6, or 12 weeks postoperatively. Difficulties with cast immobilization led nine of 16 animals to be full weight bearing too early, leading to rupture of their repairs. The seven tendons with successful primary repairs (gap <2 mm) underwent histological examination. This in vivo study demonstrates that use of the Teno Fix™ in “suture” of dog flexor tendons did not lead to scarring at the tendon surface, does not cause an inflammatory reaction within the tendon and does not interfere with tendon healing.
