🔍 Key Findings
- 97.4% of dogs returned to normal function after total hip replacement using the BFX lateral bolt.
- Mean femoral stem subsidence was 1.22 mm, with most occurring in the first month and minimal thereafter.
- Postoperative complication rate was 13.6%, with 9.2% major and 4.4% minor complications.
- Femoral fractures (3.6%) and coxofemoral luxations (3.6%) were the most common major complications.
- Increased age and higher stem size were risk factors for postoperative femoral fractures; CFI >2.0 was also associated.
- Medial calcar fractures were avoided, and fractures occurred distal to stem ingrowth zone, simplifying repairs.
- Three cases underwent prophylactic plating, all with excellent outcomes and no complications.
- Explant rate was 2.6% (5/195), with most failures involving acetabular cup rather than femoral stem.
