Flexural limb deformities in foals cause pain and welfare harm if untreated. Early intervention through splinting, physiotherapy, or surgery restores normal limb function and welfare.
Flexural limb deformities cause welfare harm through pain from abnormal weight distribution and locomotion. Foals with contracted digital flexor tendons that cause knuckling at the fetlock — walking on the dorsal surface of the hoof — experience skin trauma, pain, and inability to move normally. The welfare urgency scales with severity and the rate of progression. Severe congenital deformities that prevent normal standing cause immediate welfare harm requiring prompt intervention.
The treatment period also has welfare implications. Splinting and casting provide corrective mechanical forces but must be monitored vigilantly for pressure sores — casts that rub cause skin damage and pain that compounds the primary welfare problem. Regular cast changes and careful padding technique minimize iatrogenic welfare harm during corrective treatment.
