Which limbs bear approximately 60% of a horse's weight when standing?
Forelimbs
All limbs equally
Hindlimbs
Diagonal pairs
The forelimbs support about 60% of a horse's weight due to the center of mass being located ahead of the barrel. The hindlimbs bear the remaining 40%, providing propulsion rather than primary support.
What visual sign is most indicative of forelimb lameness?
Head nod when landing on the lame limb
Head nod when landing on the sound limb
Tail swish with each stride
Hip hike on the lame side
A head nod that coincides with landing on the lame forelimb is a classic sign of forelimb lameness as the horse tries to unload that limb. Head nods in the opposite phase or other behaviors do not specifically localize forelimb pain.
Which of the following is a common cause of hindlimb lameness?
Navicular syndrome
Laminitis
Seedy toe
Hock osteoarthritis
Osteoarthritis of the hock joint is a frequent source of hindlimb lameness due to repetitive stress. Laminitis and navicular syndrome primarily affect the forelimbs, while seedy toe involves hoof wall separation rather than lameness from the hindlimbs.
Which joint is stressed during a carpal flexion test?
Fetlock joint
Coffin joint
Carpal joint
Hock joint
A carpal flexion test places sustained flexion on the knee or carpal joint, revealing discomfort or pain specific to that joint. Flexion of other joints targets different areas of the limb.
What tool is used to detect increased hoof wall temperature indicating inflammation?
Stethoscope
Hoof tester
Hoof gauge
Infrared thermometer
An infrared thermometer or thermography camera is used to detect changes in hoof wall temperature, signaling inflammation. A hoof tester measures pressure sensitivity, while stethoscopes and gauges do not assess temperature.
Which nerve block would you perform to isolate pain to the navicular apparatus?
High palmar nerve block
Abaxial sesamoid nerve block
Low palmar nerve block
Palmar digital nerve block
A palmar digital nerve block desensitizes the hoof including the navicular region and distal interphalangeal joint. More proximal blocks affect additional structures and are used to localize higher up the limb.
A positive carpal flexion test indicates pain in which joint?
Coffin joint
Hock joint
Carpal joint
Fetlock joint
The carpal flexion test specifically stresses the carpal joint by holding it in flexion before release. Increased lameness after this test localizes the problem to the carpus.
During palpation of the frog, sensitivity suggests which condition?
Sole bruise
Laminitis
Collateral ligament injury
Navicular syndrome
Localized pain when pressing on the frog most often indicates a sole bruise. Navicular syndrome pain is higher at the heel, laminitis presents more diffuse sensitivity, and collateral ligament injury is usually felt at the coffin joint margins.
Which imaging modality provides the highest sensitivity for detecting osteochondral fragments in the stifle?
Computed tomography
Scintigraphy
Ultrasound
Radiography
Computed tomography offers cross-sectional detail and high contrast, making it more sensitive than radiography or ultrasound for small osteochondral fragments. Scintigraphy shows bone turnover but lacks fine detail.
After diagnosing a superficial digital flexor tendon injury, which rehabilitation strategy is most appropriate?
Cold water hydrotherapy only
Immediate full turnout
NSAIDs only
Controlled exercise program
A structured, controlled exercise program promotes proper fiber alignment and gradual loading during tendon healing. Immediate turnout may overload the tendon, while passive modalities alone are insufficient without exercise.
Which clinical sign is most indicative of hindlimb lameness?
Hip hike
Head bob
Tail swish
Ear tilt
A hip hike, where the pelvis on the lame side is elevated during weight bearing, is a classic indicator of hindlimb lameness. Head bob is associated with forelimb issues, and ear or tail movements are nonspecific.
A horse with unilateral swelling and heat over the coffin joint would best be localized with which diagnostic block?
Ultrasound
Abaxial sesamoid nerve block
Bone scintigraphy
Distal interphalangeal joint flexion test
An abaxial sesamoid nerve block desensitizes the coffin joint and adjacent structures, confirming pain in that region. Flexion tests, imaging, and scintigraphy help but do not provide immediate localization via anesthesia.
A skyline radiographic view is most useful to evaluate which structure?
Coffin bone
Fetlock joint
Navicular bone
Distal radius
The skyline or palmaroproximal-palmarodistal view projects the navicular bone parallel to the beam for detailed assessment. Other structures are better imaged in lateral or dorsopalmar views.
Which condition is a contraindication for cold therapy?
Tendon injury
Bacterial infection
Acute inflammation
Circulation compromise
Cold therapy reduces pain and inflammation but should be avoided if circulation is compromised, as it may worsen perfusion deficits. It is routinely used in acute inflammation and tendon injuries.
A slight gait asymmetry that is difficult to observe in a straight line but becomes more apparent under stress is classified as which AAEP lameness grade?
Grade 3
Grade 1
Grade 4
Grade 2
Grade 1 lameness is subtle and difficult to observe at a walk but detected under certain conditions. Higher grades indicate more obvious and consistent lameness.
In nuclear scintigraphy, increased uptake in the proximal sesamoid bones most likely indicates which condition?
Navicular syndrome
Sesamoiditis
Distal interphalangeal joint arthritis
Suspensory desmitis
Increased radiopharmaceutical uptake in the sesamoid bones is characteristic of sesamoiditis due to active bone remodeling. Navicular and suspensory lesions localize elsewhere, and DIP arthritis shows uptake at the coffin joint.
A positive distal limb flexion exacerbates a hindlimb lameness but whole-limb flexion does not. Pain is most likely localized to which region?
Tarsus
Digit
Hock
Stifle
Distal limb flexion stresses the digit and its soft tissue and joint structures, producing pain confined to that region. Whole-limb flexion adds stress to higher joints such as the hock and stifle.
Which instrument measures ground reaction forces to quantify the timing differences in hoof contacts for lameness analysis?
GPS tracker
High-speed camera
Force plate
Electrogoniometer
Force plates record precise ground reaction forces and timing, allowing objective quantification of asymmetries in hoof contacts. Cameras record motion but not force, while GPS and goniometers measure position and angles, respectively.
A horse exhibits fetlock valgus deformity with pain on medial palpation. Which structure is most likely injured?
Medial collateral ligament
Suspensory ligament
Superficial digital flexor tendon
Lateral collateral ligament
Valgus deformity with medial pain and instability implicates the medial collateral ligament of the fetlock. Lateral collateral injuries cause varus deformities, and tendon injuries present differently.
During tendon healing, ultrasound shows a 15% increase in cross-sectional area. This change most likely indicates what?
Acute inflammation
Appropriate healing
Tendon atrophy
Excessive scar tissue formation
A marked increase in tendon cross-sectional area indicates fibrosis and scar tissue rather than healthy remodeling. Appropriate healing usually shows organized fiber alignment without significant enlargement.
