Treating navicular syndrome in equine patients.

Summary
Navicular syndrome remains a challenging condition in equine practice due to its multifactorial aetiology and progressive nature, affecting not only the navicular bone itself but also the bursa, deep digital flexor tendon, and surrounding soft tissue structures of the navicular apparatus. Waguespack and Hanson's 2013 review synthesised the evidence for both conservative and surgical management approaches, emphasising that effective treatment strategies must be individualised based on clinical severity, the horse's intended use, and owner compliance. Conservative management—comprising controlled rest, precise hoof balance with corrective farriery, systemic anti-inflammatory medications, hemorheologic agents, and intra-articular injections—remains the first-line approach, whilst surgical options such as collateral ligament desmotomy or palmar digital neurectomy are reserved for cases refractory to medical therapy. Emerging adjunct therapies including acupuncture and extracorporeal shock wave therapy have gained traction, though the evidence base remains developing. Since navicular syndrome lacks a definitive cure and manifests through varied pathological mechanisms, the clinical goal centres on symptom management and slowing degenerative progression rather than resolution, making individualised, multimodal protocols—developed collaboratively between veterinarians, farriers, and therapists—essential to optimising outcomes in affected horses.

Practical Takeaways
- •Develop treatment plans by considering severity of clinical signs, intended use and workload demands, and owner compliance—no one-size-fits-all approach exists for navicular cases.
- •Hoof balance and corrective trimming/shoeing form the foundation of nonsurgical management alongside medical therapy; these should be primary focus before pursuing surgical intervention.
- •When medical therapy fails, palmar digital neurectomy is the most commonly performed surgical option, though collateral ligament desmotomy remains an alternative depending on pathology.
Key Findings
- •Navicular syndrome is a chronic, progressive condition affecting multiple structures of the navicular apparatus including the navicular bone, bursa, DDFT, and associated soft tissues.
- •Treatment options include nonsurgical approaches (rest, hoof management, systemic antiinflammatories, hemorheologic medications, intraarticular medications) and surgical options (collateral ligament desmotomy, palmar digital neurectomy).
- •Adjunct therapies such as acupuncture and extracorporeal shock wave therapy have recently been incorporated into navicular syndrome treatment protocols.
- •No definitive cure exists for navicular syndrome; treatment is individualized and directed toward managing clinical signs and retarding degenerative changes.
