String Halt and its Management in a Mare

A six year old mare was presented with involuntary and exaggerated upward flexion of right hind limb during walk, graze or exercise.The animal was operated after confirming as string halt condition. Two linear incisions were given over lateral digital extensor muscle and tendon joint and distal end of lateral digital extensor tendon before it joins the tendon of long extensor. First distal portion of tendon was transected then proximal portion with muscle belly. Mare showed an almost immediate improvement with complete recovery within 2 weeks.
