Description
Provides a fully updated Seventh Edition of the classic gold-standard reference on equine lameness
This new edition of the go-to resource for equine lameness features updates throughout and more in-depth information on objective lameness assessment, sports medicine, rehabilitation, treatment options, and advanced imaging. With contributions from the world’s leading authorities on the subject, the book covers functional anatomy, examination, imaging, lameness of the distal limb, proximal limb, and axial skeleton, principles of musculoskeletal disease, therapies, occupation-related conditions, lameness in young horses, and farriery. More than 1,700 images support the text, making it an exhaustive reference for all aspects of lameness in horses.
Now in its seventh edition, Adams and Stashak’s Lameness in Horses continues to be the definitive resource on equine lameness for veterinary specialists, practitioners, interns, residents, and students alike. The book is supplemented with a companion website offering a plethora of “how-to” videos demonstrating a variety of different physical examination techniques, including palpation, hoof testing, flexion tests, and perineural and intrasynovial injection techniques.
- Offers a fully revised new edition of the classic text on equine lameness
- Includes more extensive information on objective lameness assessment, sports medicine, rehabilitation, treatment options and advanced imaging
- Features over 1,700 images to illustrate the concepts described
- Written by internationally renowned experts in the field
- Includes access to a companion website with "how-to" videos
Adams and Stashak’s Lameness in Horses is a must-have reference for any practicing large animal and equine veterinarian, equine veterinary specialist, or veterinary student dealing with lameness in the horse.
