2024年5月24日 · Biomedtrix BFX® cementless total hip replacement (THR) requires the use of femoral broaches to prepare a press-fit envelope within the femur for subsequent stem insertion. Current broaches contain teeth that crush and remove cancellous bone; however, they are not particularly well-suited for broaching sclerotic (corticalized) cancellous bone.

The Collared Stem is designed to achieve press-fit stabilization with an identical femoral preparation and similar stem insertion technique as is practiced for a collarless BFX EBM Stem.

2025年1月15日 · Older dogs and a lower femoral canal flare index (stovepipe morphology) have been associated positively with postoperative fractures in dogs treated with the older design BFX standard stem. 20 A recent large case series with dogs receiving a BFX lateral bolt stem showed an association between fractures and increased age. 29 Another recent study ...

2025年2月14日 · To determine the effect of broach tooth design on THR stem insertion, a BFX® stem was inserted into prepared test blocks and insertion and subsidence energy and peak loads were determined.

Biomedtrix BFX® cementless total hip replacement (THR) requires the use of femoral broaches to pre-pare a press-fit envelope within the femur for subsequent stem insertion.

2024年5月24日 · To determine the effect of broach tooth design on THR stem insertion, a BFX® stem was inserted into prepared test blocks and insertion and subsidence energy and peak loads were determined.

Precision acetabular reamers and femoral broaches are used for bone preparation. The implants are firmly and tightly seated into a prepared bone bed. The precise match of geometry and support by adjacent bone around the implant, combined with specific implant design features, works to maintain the implant position within the bone.

2023年3月7日 · For each pair of femora, one BFX + lb and one CFX implant was placed, alternating right and left femurs for each implant type. The BFX femur was prepared first, and stem sizing was confirmed during implantation based on achieving a press-fit feel during broaching and BFX + lb implantation.

2025年2月14日 · Models of the femoral stem implant (BioMedtrix BFX™ number 4 Stem) were superimposed over the solid bone models to confirm the 3D templating of the femoral implant size and determine the drilling and broaching axis of the proximal femur.

2024年5月24日 · To determine the effect of broach tooth design on THR stem insertion, a BFX ® stem was inserted into prepared test blocks and insertion and subsidence energy and peak loads were determined. Results: Broach tooth design led to significant differences in broaching energy and peak broaching loads in test blocks of both densities.
