🔍 Key Findings
- GTO enabled successful cementless THR in dogs with severe medialization of the greater trochanter or chronic craniodorsal hip luxation.
- All 5 hips had acceptable long-term outcomes (median follow-up: 48 months) with full function and no persistent complications.
- Only one major complication occurred—a luxation unrelated to the GTO and successfully corrected with cup revision.
- GTO facilitated femoral canal access and gluteal preservation, reducing risk of iatrogenic injury during broaching.
- All GTOs healed radiographically (4 by 6 weeks, 1 by 12 weeks), with no cases of nonunion or implant migration.
- No complications related to GTO or PTBW fixation (pins + tension band) were observed in any dog.
- Surgical planning included templating both THR and GTO to ensure ideal alignment and reduce fracture risk.
- GTO may be especially valuable in luxoid hip dysplasia phenotypes or chronically fixed luxations.
