PBG Proximal Bone Growth Cementless Stem

Features:

• 3° biplanar taper design matches natural femoral canal.
• Load transfer takes place superior to the metaphyseal-diaphyseal junction and avoid stress shielding in the distal part.
• Three point contact and fixation achieve immediate rotational stability.
• Proximal Vacuum Plasma Titanium Coating: 200um thickness, 200um pore size, and 30% porosity, ensure bone in-growth.
• Grit-blasted diaphyseal region provides ongrowth surface.
• Polished distal bullet tip avoids cortical impingement and reduces thigh pain.

Indications:

• Severe painful and/or disabled joint from osteoarthritis, traumatic arthritis, rheumatoid arthritis, or congenital hip dysplasia
• Avascular necrosis of the femoral head
• Acute traumatic fracture of the femoral head or neck
• Failed previous hip surgery including joint reconstruction, internal fixation, arthrodesis, hemiarthroplasty, or total hip replacement
• Certain cases of ankylosis
