FIgure 3. pronounCeD SIDeBone on The lATerAl SIDe

A modern view on sidebone By JASon SoMerVIlle BSC (honS) AWCF introduCtion

most farriery books refer to sidebone in the context of the heavier horse breeds, this was the case when the majority of horses shod by farriers were working horses. these horses worked at a slower pace and often on hard surfaces requiring a traditional sidebone style shoe (Fig 1).

The modern horse likely to be diagnosed with sidebone is a hunter type or sports horse with a conformation defect. These horses are working at fast speeds and on a variety of surfaces including slippery surfaces such as grass. The style of shoeing has to fit the type of horse and the work that it has to perform, as well as helping to reduce the clinical symptoms of sidebone.

The hoof has a number of soft structures within it that are design to facilitate the movement of the hoof wall and dissipate concussion. These structures include the digital cushion, coronary band, frog, and lateral cartilages of the foot. These perform an important part of the shock absorbing mechanisms, and if any of these structures are compromised then the foot’s ability to dissipate shock is compromised. In the case of sidebone, the lateral cartilages of the foot are affected and these are considered to be important in the reduction of concussion (Butler 1985).

The lateral cartilages are located on both the medial and lateral sides of the foot, and are

rhomboid in shape. The cartilages are a thick, tough fibrocartilage that are held in place by four ligaments. The cartilage is thickest where it attaches to the palmar process of the distal phalanx (Fig 2). It attaches to the distal phalanx
