Foot pain is the most common cause of lameness in horses. In sport horses, podotrochlear syndrome (‘navicular syndrome’) is reported to be the most frequent condition affecting the front foot. Ultrasonography has the potential to detect damage to the soft tissues as well as the bone surfaces; in some clinics it has become the technique of choice for the identification and documentation of many podotrochlear injuries.

Objective—To determine the effect of differences in structural and mechanical tendon properties on functionality of the passive stay apparatus in horses.

Sample—5 forelimbs each from nondwarf Friesians, dwarf Friesians, and ponies.

Objective: To describe partial removal of the intrathecal component of the deep digital flexor tendon (DDFT) in horses with chronic septic DDF tendonitis and tenosynovitis unresponsive to conventional therapy, and to report long-term outcome.

Study Design: Case series.

Animals: Horses (n=4).

Objective: To report outcome after the surgical treatment of lacerations of the superficial digital flexor tendon (SDFT), deep digital flexor tendon (DDFT), suspensory ligament (SL), and/or distal sesamoidean ligaments (DSL) in horses.

Study Design: Case series.

Animals: Horses (n=106) with lacerations of the SDFT, DDFT, SL, and/or DSL.

Methods: Medical records (1988–2002) were reviewed for signalment, limb and tendon/ligament involvement (location and extent of injury, tendon sheath involvement), method of repair, and outcome.

Objective: To report outcome after desmotomy of the accessory ligament of the deep digital flexor tendon (ALDDFT) in adult horses (≥2 years) for treatment of desmitis of the ALDDFT or flexural deformity of the distal interphalangeal joint (FDDIJ).

Study Design: Case series.

Animals: Horses with desmitis of the ALDDFT (n=9) and FDDIJ (n=15).

Methods: Records (April 1996–July 2008) of 24 adult horses (mean age, 6.7 years) that had ALDDFT desmotomy were reviewed. Follow-up data was obtained 12–120 months after desmotomy.

Seven isolated equine front limbs were used to establish the normal T1 relaxation time of equine superficial digital flexor tendon (SDFT), deep digital flexor tendon (DDFT), and suspensory ligament (SL) using magic angle magnetic resonance (MR) imaging. MR imaging of the metacarpi was performed with the limbs positioned at 55° (the magic angle) relative to the main magnetic field. Transverse spin-echo proton density and inversion recovery images were acquired. T1 relaxation time was calculated based on ratios of signal intensity determined from the different pulse sequences.

Reasons for performing study: The assessment of a normal range for cross-sectional area (CSA) of tendons in the tarsal region is important in order to use them as reference values in the identification of pathological changes of dimensions.

Objectives: To provide normal reference values for the CSA of the tendons of the tarsus of Standardbred trotter horses (STH) by means of ultrasonography.

Methods: Transverse echographic images of the tendons were obtained at different levels proximodistally; these images were digitised and CSA values (mean ± s.d.) were obtained for each structure.

Transection of the deep digital flexor tendon is a controversial treatment for chronic laminitis largely because of the variation in personal experience with the procedure and the varying success rates reported in the previously published data. Differences in reported success rates are more likely because of the dissimilarities in foot pathology and the foot management associated with the procedure. This report presents 245 tenotomy cases, in which all cases received the same shoeing protocol (realignment shoeing).

The effectiveness of new therapies to treat tendon injuries is difficult to determine and is often based on semi-quantitative methods, such as grey level analysis of ultrasonographic images or subjective pain scores. The alternatives are costly and long-lasting end-stage studies using experimental animals.

Superficial digital flexor tendon lesion is an important cause of lameness in equine athletes. Although numerous treatments have been described, few are effective at promoting significant improvement in the quality of the extracellular matrix. Therefore, great potential remains for recurrence and in certain cases, an abrupt end to the horse’s athletic career. Recently, several experiments have focused on the therapeutic potential of mesenchymal stem cells (MSCs) in cases of tendon lesions.
