In this episode of The Hoofcare Companion, we explore the collateral ligaments of the equine lower limb, examining their anatomy, location, function and importance in maintaining joint stability during locomotion. Collateral ligaments play a vital role in controlling excessive movement within joints, resisting abnormal lateral and medial displacement, and maintaining the structural integrity of the equine limb. Injury to these structures can result in lameness, reduced athletic performance and, in more severe cases, joint instability. We examine the medial and lateral collateral ligaments of the fetlock (metacarpophalangeal and metatarsophalangeal joints), proximal interphalangeal joint (pastern) and distal interphalangeal joint (coffin joint). We also consider the collateral ligament complexes of the carpus and tarsus. Throughout the episode, we discuss the associated pathologies, including desmitis, desmopathy and enthesopathy, and explain how these injuries may develop through trauma, repetitive loading and abnormal biomechanical forces. We explore the veterinary diagnostic process, including clinical examination, diagnostic analgesia, radiography, ultrasonography and MRI, highlighting the importance of accurately identifying the injured structure. Particular attention is given to the farrier's role in managing collateral ligament injuries. We consider how hoof balance, mediolateral support, breakover, shoe selection and the distribution of ground-reaction forces may influence loading through affected joints. We also discuss the importance of collaboration between veterinary surgeons and farriers when developing appropriate treatment and rehabilitation strategies. In this episode, we cover: • Anatomy and precise locations of the equine collateral ligaments. • The function of medial and lateral collateral ligaments. • Fetlock, pastern and coffin joint collateral ligament injuries. • Carpal and tarsal collateral ligament complexes. • Common causes and clinical signs of ligament pathology. • Veterinary diagnostic techniques and advanced imaging. • Treatment options and ligament healing. • Farriery considerations and therapeutic shoeing principles. • Rehabilitation, prognosis and return to work. Understanding collateral ligament anatomy is essential for farriers, veterinary surgeons, veterinary students and equine professionals involved in identifying, managing and rehabilitating horses with musculoskeletal injuries.
