A good working knowledge of musculoskeletal anatomy is important to understand the clinical impact of injuries to the muscle–tendon unit (ie, strains). Strains are common in small animals and should be included in the differential list for any type of lameness or decrease in working or sporting performance. Clinicians should always take a complete history, perform a thorough examination, and obtain radiographs of the affected region to evaluate bony structures. Ultrasonography, CT, and MRI offer more complete evaluation of the muscle–tendon unit and can aid in diagnosis and guide treatment.
Following are the author’s most common muscle and tendon injuries to consider in the lame patient.
