🔍 Key Findings
Study population: 73 hips from 60 dogs undergoing cementless THR.
Methods evaluated:
- ACVD/ACOLL (acetabular circle on VD or OLL view)
- ALVD/ALOLL (acetabular line)
- FHCVD/FHCOLL/FHCCCHB (femoral head circle)
- Intraobserver repeatability and interobserver consistency were excellent for ACVD and ACOLL.
- FHC methods consistently underestimated actual cup size by 2.4–3.6 mm.
- AC and AL methods had low bias (±0.5 mm) and better predictive value.
- OA severity negatively affected the accuracy of all measurements (p < .05).
- Highest predictive accuracy was ~49% using ACVD with rounding down protocol.
