Laminitis

Reasons for performing study: In the treatment of laminitis it is believed that reducing tension in the deep digital flexor tendon by raising the palmar angle of the hoof can reduce the load on the dorsal lamellae, allowing them to heal or prevent further damage.

Objective: To determine the effect of alterations in hoof angle on the load in the dorsal laminar junction.

Despite ongoing research and a widening range of treatment options, laminitis remains a severely damaging condition with poorly understood pathophysiology. Results obtained from cytokine regulation studies during the last decade have highlighted the inflammatory nature of laminitis. This review will describe the role of systemic activation and local infiltration of neutrophils in laminar tissues in the induction of laminitis.

Reasons for performing study: Anatomical change within a laminitic foot is of diagnostic and prognostic importance. A lateromedial radiograph represents the current ‘gold standard’ by which these changes are identified. Detection of anatomical change is dependent upon a priori knowledge of normality and subjective assessment alone may not identify modest change. Normal baseline data is, therefore, needed against which objective comparisons can be made. There is little information regarding the radiological anatomy of the donkey foot, hence an equine model has been widely adopted.

Objectives: To determine the temporal progression of lamellar BM changes and whether laminin-332 (Ln-332) 2 cleavage products are generated during laminitis development.

This study compared three subjective scoring systems used to assess lameness associated with equine laminitis: (1) visual analogue scale, (2) Obel score and (3) clinical grading system (CGS). Two groups of 12 observers, consisting of equine veterinarians and final-year veterinary students, scored lameness severity after watching video footage of 14 horses on two occasions. Generalizability theory was used to investigate the reliability of the three systems and the effects of observer experience. Overall reliability across all times and observers was high.

Laminitis is a disease that represents a loss of the normal homeostatic mechanisms that control the day-to-day function of the distal phalanx. The degree or severity to which homeostasis is affected is directly related to the severity and the final outcome for the equine patient. A systematic approach including the physical examination, digital radiography, venography, and newer techniques such as computer tomography and magnetic resonance imaging can assist the clinician in developing a prognosis for the acute and chronic laminitis case.

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).

Reasons for performing study: To evaluate quantitative sensory testing (QST) of the feet of laminitic horses using a power-assisted hoof tester.

Hypothesis: Hoof Compression Thresholds (HCTs) can be measured reliably and are consistently lower in horses with chronic laminitis than in normal horses.

The goals of mechanical treatment during the acute phase of laminitis are to preserve the lamellar interface by reducing the forces that are compromising its integrity and to make the horse more comfortable. Early decision making is important in managing acute laminitis. This article helps the practitioner to identify some of the commonly used and accepted methods of protecting the laminitic foot. The materials available and the theories behind their use are also described. The laminitic foot needs to be understood before determining methods for its support.
