Cementless Total Hip Replacement in 20 Juveniles Using BFX™ Arthroplasty


To describe outcome after a minimum of 1 year for total hip replacement (THR) using BioMedtrix BFX™ biologic fixation implants in skeletally immature dogs (6–10 months of age).


Medical records (November 2007–June 2010) of 20 dogs, 6–10 months old that had cementless THR were reviewed. Preoperative, immediate, 6-week and >1-year postoperative radiographs were compared. Clinical examination was performed at 6 weeks and >1 year postoperatively. Owner questionnaire was obtained at final follow-up.


Cementless THR using BFX™ implants was performed because of debilitating coxofemoral pain, resulting from canine hip dysplasia, after unsatisfactory outcome with medical management. Radiographs taken immediately, 6 weeks and at a mean of 29.8 months (range, 12–48 months) postoperatively revealed satisfactory implant positioning and stability. Significant change in measured cranial–caudal femoral stem fill and level (P
