Hip

Structural models allow for foreseeing geometrical and structural outcomes of surgical choices

Canine hip dysplasia (CHD) and elbow dysplasia (ED) impact the health and welfare of all dogs. The first formally organized assessment scheme to improve canine health centered on reducing the prevalence of these orthopedic disorders.

Overall prevalence 24.9%, slightly higher in males, more severe in bilateral than unilateral cases

Varus stem angulation should be avoided to prevent fissures. Canal fill is a poor indicator of optimal stem size.

The original Zurich cup geometry is distorted as a consequence of the press-fit mechanism

There is a paucity of clinical reports focusing solely on HD in cats

Asymmetrical hip conformation may be the sequela of a LTV and mask or aggravate genetically induced canine hip dysplasia

OBJECTIVES: A very limited safe anatomical window for transiliosacral implant placement exists in cats (<0·5 cm 2 ). Lag screw fixation requires multiple bilateral implants thus increasing the risk of iatrogenic trauma and implant interference. We describe a safe and effective method for bilateral sacroiliac fixation in cats using a single implant to minimise inadvertent iatrogenic damage to local structures and restore pelvic canal diameter.

Femoral head ostectomy, as described for dogs, provided a favorable outcome in this species.

The use of intra-operative radiology can significantly improve the quality of lag screw insertion for the stabilization of sacroiliac luxations in cats
