Question 1
What is lameness and what signs can you use to identify the affected limb?
![Page 3: Key Issues Presentation](https://reader030.fdocuments.net/reader030/viewer/2022032505/55c4f953bb61eb46508b483e/html5/thumbnails/3.jpg)
Question 1• What is lameness?
– When the animal is unable to walk without difficulty; having an abnormal gait or posture
• What signs can you use to identify the affected limb?– (applies to both forelimb)
• Lame limb:– Non-weight bearing– More inclined to protract– Shorter strides
• Head position/nodding– Head drop on sound limb– Up on lame limb
• Unable to turn smoothly

Question 2
What techniques could you use in each case to try and localize the source of the
lameness?
![Page 5: Key Issues Presentation](https://reader030.fdocuments.net/reader030/viewer/2022032505/55c4f953bb61eb46508b483e/html5/thumbnails/5.jpg)
General Techniques:• Clinical History• Physical Examination– Observation– Palpation– Manipulation
• Diagnostic Imaging
Species Specifics Techniques:• Equine:
– Gait Assessment• Straight-Line • Lunge (circle)
– Diagnostic Nerve Blocks• Perineural Blocks• Intrasynovial Blocks
– Diagnostic Scintigraphy (physiological imaging)
• Canine:– Manipulation Tests
• Cranial Drawer Test• Tibial Thrust
Question 2
![Page 6: Key Issues Presentation](https://reader030.fdocuments.net/reader030/viewer/2022032505/55c4f953bb61eb46508b483e/html5/thumbnails/6.jpg)
Question 3
What criteria could you use to grade the severity of the lameness in each case?
![Page 7: Key Issues Presentation](https://reader030.fdocuments.net/reader030/viewer/2022032505/55c4f953bb61eb46508b483e/html5/thumbnails/7.jpg)
Grading Equine Lameness (AAEP Scale)0. Lameness not perceptible under any circumstances1. Lameness is difficult to observe and is not consistently apparent, regardless of circumstances2. Lameness is difficult to observe at a walk or when trotting in a straight line but consistently apparent under certain circumstances3. Lameness is consistently observable at a trot under all circumstances4. Lameness is obvious at a walk5. Lameness produces minimal weightbearing in motion and/or at rest or a complete inability to move
Other scales include the Modified Scoring System, and scales on a 0-10 basis.
Grading Canine Lameness0. Stands and walks normally 1. Stands with abnormal posture and walks without lameness2. Mild lameness when walking3. Moderate lameness when walking 4. Severe lameness when walking5. Non-weightbearing
Objective assessment such as force plate or pressure mat analysis can be used in order to more accurately grade lameness.
Question 3
In both cases, numerical grading can be extremely subjective. Animals should be graded on the same scale by all professionals involved.

Question 4
What directional terminology would you use to accurately describe the location of
the abnormality?

Bouncer: Dysplasia of elbow joint on right fore limb. • Elbow joint found on caudal aspect
of proximal limb, distal to the shoulder joint.
Flash: SDFT lesion on left fore limb.
• SDFT located on caudal aspect of limb • It begins at the palmer aspect of the carpus and
crosses the palmer aspect of the proximal interphalangeal joint, inserting on the middle phalanx.

Question 5
What diagnostic techniques could you use in each case to try and determine the
cause of the lameness?
![Page 11: Key Issues Presentation](https://reader030.fdocuments.net/reader030/viewer/2022032505/55c4f953bb61eb46508b483e/html5/thumbnails/11.jpg)
Bouncer (Canine):• Manual palpation of the limb• Radiology/Ultrasound• Arthrocentesis• CT / MRI• Blood sampling for biochemistries
Flash (Equine):• All of the above tests mentioned• Equine Nerve Block
Question 5

Question 6
What would you need to know about how bones heal
in order to successfully manage a fracture?
![Page 13: Key Issues Presentation](https://reader030.fdocuments.net/reader030/viewer/2022032505/55c4f953bb61eb46508b483e/html5/thumbnails/13.jpg)
Type of Bone:• Lamellar Bone
• Compact bone (bone outer surface)
• Spongy bone (bone interior) • Woven Bone
• Temporary bone during healing • Random orientation of collagen
fibers• Often replaced by lamellar bone
Location of fracture relative to structure:• Diaphysis• Metaphysis (often growth plates
involved)• Epiphysis

Question 6
Fracture Healing Times:

Healing Complications:• Inadequate blood supply• Leading to cartilage formation• Necrosis can occur
• Instability• Lots of movement and tension
will encourage development of a fibrous tissue callus
• Fibrous tissues won’t stabilize fractures
