Funktionell-anatomische Untersuchungen an den Zehengelenken (Articulationes interphalangeae) der Schultergliedmaße des Pferdes

description: Functional anatomical investigations on the interphalangeal joints of the forelimb in the horse. The proximal and distal interphalangeal joints are of particular importance in sporting horses, as degenerative diseases or fractures lead to a loss in performance. It was the objective of this study to investigate several biomechanical properties of the coffin and pastern joints. Forty three specimens of 30 male and female horses of different breeds and sizes were examined. Their age ranged between 3 months and 30 years. Using computertomographic osteoabsorptiometry (CT-OAM), the distribution of the subchondral bone density was determined topographically in three-dimensional reconstructions of the distal and proximal interphalangeal joints. The specimens were divided into 6 age groups. Following exarticulation the joints were evaluated for chondral lesions. These were documented by using a template of the respective articular surface and were summed up graphically in order to demonstrate the most common locations for chondral damage. The size of the articular surfaces was determined in order to investigate a relationship between the subchondral bone density and the size of the joints. Five specimens (coffin joint and pastern joint) were examined with regard to split lines in the articular cartilage. The articular cartilage was pierced at regular intervals (2 mm) at 90° angles with needles that had previously been dipped into ink. The subchondral plate of four specimens (proximal and distal interphalangeal joint), after maceration and demineralisation, was investigated with regard to subchondral split lines in the same way as described above. The CT-OAM shows a relatively low subchondral bone density in the first age group (horses up to 9 months). In the following age groups the bone density generally increased, varying with the age of the horse. The maximum bone density is found in the palmar areas of the coffin joint and the pastern joint. As far as the coffin joint is…
