The clinical signs and diagnostic imaging of two adult llamas with severe metatarsophalangeal valgus angular limb deformity causing metatarsophalangeal instability, severe osteoarthritis and marked bilateral hindlimb lameness are described. The metatarsophalangeal axis was corrected and arthrodesis of the metatarsophalangeal joint was achieved by distal medial metatarsal condylectomy and the medial application of a custom‐made angled 4·5 mm dynamic compression plate. A secure construct with normal limb angulation and a good biomechanical outcome was achieved in each of the hindlimbs of both llamas. The development and final dimensions of the implants are described to assist decision making during the evaluation of the surgical management of such cases.
