Hip

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

A possible successful option to provide immediate stem stability for revision of a loosened BFX stem with a properly osseointegrated cup

Regional periprosthetic acetabular bone grayscale value varies with the design of THA.
