2 One of most common skeletal diseases in dogs Incidence in cats is lower than in dogs Hip Dysplasia Breeds: Large breed dogs St. Bernard, G. Shepherd, Labs, Golden Ret, Rottweiler

3 Positive Ortolani Sign Lateral recumbency Femur pushed upward toward the spine If laxity exists, the head of the femur subluxates out of the acetabulum

4 Positive Ortolani Sign From this position, the leg is then abducted (moved outward from the body)

5 Positive Ortolani Sign The head of the femur falls back into the acetabulum and a clunk or pop can be felt

6 Hip Dysplasia: OFA guidelines Borderline no consensus between radiologists to classify hip as Normal or Dysplastic

61 Hip Luxation Hit by horse

62 Hip Luxation Coonhound jumped off balcony after a bird

63 Ehmer Sling A true Ehmer sling encircles the animal s body

64 Hip Luxation Treatment Open reduction = surgical reduction of the luxation (1) Capsulorrhaphy Resuture the torn capsule. Often there isn t enough capsule left to suture

65 Hip Luxation Treatment (2) Toggle Pin Drill hole through femoral head Drill hole through acetabulum Use toggle pin on inside of pelvis Anchor suture to toggle pin; run the suture backwards through the acetabulum and femur and secure.

66 Hip Luxation Treatment (3) Prosthetic Capsule Screws placed in the dorsolateral acetabulum. Hole drilled through neck of femur. Suture passed from screws through hole in neck and tightened.

67 Hip Luxation Treatment (4) Greater Trochanter Translocation Trochanteric osteotomy.. Reflect gluteal musculature proximally Using osteotome and mallet, prepare new site caudal and distal to normal location. Secure with small pins and orthopedic wire

75 Declaw Considered inhumane by some people Outlawed in many European countries San Francisco advises against it It is an amputation of the distal phalanx of cat s toes

76 Declaw Postop Complications Owners need to be aware that significant lameness may result for up to 2 weeks after surgery Radial neuropraxia is a complication from a tourniquet that was applied too tightly

77 Dock Tails Also banned in some European countries Done at 2-5 days old No anesthesia 1 stitch
