ABSTRACT
OBJECTIVE: 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.

Traumatic laceration of the posterior tibial artery is an infrequent yet potentially devastating injury. Prompt diagnosis and treatment are necessary in order to limit ischemic damage to distal tissues. A case report is presented along with a brief overview of current surgical technique.

Collapsing pes plano valgus deformity and pes cavus deformity have been identified and treated for many years. Recently, a combination of these deformities has been recognized occurring simultaneously. This multiplanar deformity is known as the cavo-valgus foot. Treatment of this foot type requires a firm understanding of planal dominance. The authors present a case report on this subject.
