Reasons for performing study: Diagnostic navicular bursoscopy has been described in limited cases. Review of greater numbers is needed to define its contribution to case management and prognostic values.
To compare in vitro biomechanical properties of a novel suture pattern to a current standard for primary repair of equine superficial digital flexor tendon (SDFT) laceration.
In vitro randomized, paired design.
Cadaveric equine forelimb SDFT (n = 24).
Reasons for performing study: Injuries of the calcaneal insertions of the superficial digital flexor tendon and their relationship to displacement of the tendon from the calcaneus have not previously been reported.
Objectives: To describe findings made on clinical cases with disruption of the calcaneal insertions of the superficial digital flexor tendon (SDFT) including observations on their role in horses with unstable subluxation of the tendon. To describe novel surgical techniques and the results of treatment.
Objective To report on the outcome of wounds to the hindlimb of racehorses, and horses with the intended use of racing, where both the long digital extensor (LoDE) and lateral digital extensor (LaDE) tendons had been completely transected. Design Retrospective case series. Methods Records of all horses admitted with hindlimb lacerations between 2002 and 2009 were examined for cases where both the LoDE and LaDE tendons in the hindlimb had been severed, and specifically in horses intended to be used for racing.
Objective—To compare in vitro expansion of equine tendon- and bone marrow–derived cells with fibroblast growth factor-2 (FGF-2) supplementation and sequential matrix synthesis with pulverized tendon and insulin-like growth factor-I (IGF-I).
Sample—Cells from 6 young adult horses.
Objective:To compare in vitro expansion, explant colonization, and matrix synthesis of equine tendon- and bone marrow–derived cells in response to insulin-like growth factor-I (IGF-I) supplementation.
Sample—Cells isolated from 7 young adult horses.
Reasons for performing study: Tears of the radial head of the deep digital flexor (DDF) have not previously been documented.
Objectives: To describe the presentation, clinical, ultrasonographic and tenoscopic features associated with tears of the radial head of the DDF and to report the results of treatment.
Hypotheses: Tears of the radial head of the DDF cause lameness and distension of the carpal sheath of the digital flexor tendons. Removal of disrupted tissue that is extruded into the sheath can result in clinical resolution and restoration of function.
Reasons for performing study: Mesenchymal stem (progenitor; stromal) cell (MSC) therapy has gained popularity for the treatment of equine tendon injuries but without reports of long-term follow-up.
Objectives: To evaluate the safety and reinjury rate of racehorses after intralesional MSC injection in a large study of naturally occurring superficial digital flexor tendinopathy and to compare these data with those published for other treatments.
Objective—To evaluate outcome after intralesional injection of insulin-like growth factor-I (IGF-I) for treatment of superficial digital flexor (SDF) tendonitis in Thoroughbred racehorses.
Design—Retrospective case series.
Animals—40 Thoroughbred racehorses.
Procedures—Medical records of racehorses with SDF tendonitis treated within 13 weeks after injury by intralesional injection of IGF-I (25 or 50 μg every other day for 4 or 5 treatments) were reviewed. Outcome was determined via analysis of race records, owner follow-up, and examination.
Reasons for performing study: Longitudinal tears (LTs) of the digital flexor tendons are an important cause of chronic tenosynovitis of the digital flexor tendon sheath (DFTS). The origin of those marginal tears is not yet fully understood. The long-term outcome after medical and surgical treatment is guarded.
Objectives: To determine the prevalence of LTs of the digital flexor tendons in a large population of horses undergoing diagnostic tenoscopy of the DFTS and to assess the outcome of surgical treatment and the factors influencing the outcome.
