A
  • dislocation of femoral head out of acetabulum
  • majority are craniodorsal
  • primarily caused by vehicular trauma

Q

Hip Dysplasia

A
  • common in large breed dogs
  • inherited, polygenic, developmental defect
  • poor formation of hip joint
  • clinical symptoms occur at 5-8 months of age
  • treatments: TPO, FHO, total hip replacement

Q

TPO

A
  • repositioning the acetabulum
  • changes in orientation of hip socket
  • reserved for younger dogs, 5 months to 1 year

Q

FHO

A
  • removing head of femur
  • trying to take away pain from arthritis
  • better done in small and medium breed dogs

Q

Cranial Cruciate Tear

A
  • most common cause of rear limb lameness
  • sudden rotation of limb when joint is flexed
  • rupture allows tibia to move cranially
  • treatments: TTA, TPLO, Extracapsular repair

Q

TTA

A
  • stabilization technique
  • counteracting the force of tibial thrust due to tilted tibial plateau
  • changing angle of pull of patellar tendon to 90 degrees

Q

Extracapsular Repair

A
  • joint stabilization
  • no more tibial thrust present
  • suture passed from lateral aspect of femur to cranial aspect of tibia
17
Q

TPLO

A
  • stabilization of stride
  • changing the angle and relationship of femur and tibia
  • will not eliminate the cranial drawer sign
18
Q

Luxating Patella

A
  • usually medial luxation
  • small/toy breed dogs
  • may be congenital or acquired
19
Q

Partial Tear of Calcanean Tendon

A
  • usually just gastrocnemius tendon
  • dropped hock, curled toes
  • usually from trauma
20
Q

Complete Rupture of Calcanean Tendon

A
  • flat footed with a dropped hock and lame
  • all tendons are ruptured
  • can also be seen with an endocrinopathy
