Musculoskeletal Diseases Flashcards
Lameness clinical sign
Can be nerve or muscukoskeletal
Look at which leg there is more weight on
Watch if there is trouble with stairs, jumping, getting up and down
Sore to touch? Swollen?
Muscle atrophy
More slow compared to nerve damage
Using muscle less
Cat leg in splinter/cast
Dog post acl surgery
Causes of swelling
Hematoma Cellulitis Bursitis Inflammation Edema Tumors Abscess
Hematoma
Collection of blood under skin
After blood collection, trauma, bleeding
Cellulitis
Diffuse infection under skin
Overall swelling, may crackle/have air
Bursitis
Inflammation of Bursa Small fluid containing sacs near joint Pain, limits movement Trauma/bone injury/infection/swollen joints Rest, steroids, NSAIDs, antibiotics
Inflammation
Muscle, joint, bone and soft tissue
Infection, trauma, immune mediated
Swelling over inflamed region
Edema
Fluid in tissues
Heart failure, lymphatic drainage
Tumor, inflammation, trauma
Tumors
Soft tissue, bone
X-ray to confirm
Benign or cancerous
Metastatic in lymph nodes
Abscess
Localized infection under skin
Cat bites, FB, trauma
Burst, puss
Deformities
Fractures and dislocation Congenital malformation Improper old injury healing? Some breeds have curved legs (bow legged) Basset hounds, beagles
Fractures
Leg twisted at odd angle Leg feels loose and limp past fracture Pain, not using leg Small (green stick) Comminuted (shattered) Multiple fracture Trauma, bone deformity, weak bones
Dislocations
Knee, hip, elbow, shoulder Vertebrae, tail Unable to use when joint unstable Trauma Hip/elbow dysplasia increases risk of dislocation Medically pop back in with GA Surgery
Patella dislocation
Dogs may kick out and pop back in
Congenital/hereditary
Deepen groove to reduce ability to pop out
Collapse/weakness
Pain, difficulty getting up, stiff/sore legs
Non specific
Muscle and neurological problem
Inflammation
Heat, redness, swelling, pain, loss of function,
Discharge if infected
Does carrying leg or weight bearing create worse problems
Carrying leg
Needs to be seen asap
Want to avoid incorrect healing
Weight barring treatment
Rest and anti inflammatory
Pet should still be seen
Bruising and hematoma
Check skin for wounds and scabs
Does limping always mean pain
No
Can mean joint fusion, previous injury, short leg congenital defects
Lameness exam
Watch dog running outside
Palpation
Flexion tests
Walk/jog
Flexion test
Extend and flex limbs and watch for pain
Do in lateral recumbency
Palpation
Feel each limb
Look for swelling and pain
Watch for biting (use muzzle)
Cranial drawer
Best to do under sedation and anesthetic
Feel forward motion of tibia in relation to femur
Radiography
Painful, hips require sedation
Bones, joints (arthritis)
Do not see tendons or ligaments or soft tissue
Problems with radiography
Don’t over extend
Could fracture weak bone tumor
What to do if you suspect cancer
Do chest X-ray
