UN Cemented TI+HA Coated Stem

The UN Cementless TI + HA Coated Stem represents the gold standard in biological fixation for modern total hip replacement (THR). Specifically engineered for the active patient, this femoral stem utilizes a synergistic combination of high-strength Titanium alloy and a bio-active Hydroxyapatite (HA) coating. Unlike cemented options, the UN stem is designed to achieve a permanent, “living” bond with the patient’s bone, ensuring exceptional long-term stability and a more natural distribution of physiological loads.

The titanium core provides an elasticity modulus that closely mimics natural cortical bone, significantly reducing the risk of stress shielding and periprosthetic bone resorption. The addition of the HA coating acts as an osteoconductive scaffold, stimulating rapid bone migration toward the implant surface. This dual-action design ensures high primary stability through a precision press-fit and secures long-term secondary fixation through comprehensive osseointegration.

Key Features & Benefits

• Bio-Active HA Coating: The Hydroxyapatite layer promotes accelerated bone healing and chemical bonding at the interface, sealing the femoral canal against wear debris and preventing early loosening.

• Titanium Alloy Core: Manufactured from high-grade Titanium for its superior biocompatibility, lightweight strength, and fatigue resistance, providing a resilient foundation for life-long performance.

• Optimized UN Anatomical Profile: Features a tapered geometry that ensures a secure “wedge” fit within the femoral canal, providing immediate rotational and axial stability upon implantation.

• Bone-Friendly Biomechanics: The material properties help maintain healthy bone density by ensuring a more natural transfer of weight along the femur.

• Precision-Machined Taper: Equipped with a standard modular taper to ensure a perfect, vibration-free fit with a wide range of femoral heads (SS, CoCr, or Ceramic).

Primary Clinical Applications

• Primary Cementless THR: The ideal choice for younger, active patients with good bone quality (Dorr Type A and B) who require a long-lasting, biological solution.

• Active Lifestyle Restoration: Provides the rigid stability and durability needed for patients returning to high-impact daily activities or sports.

• Biological Reconstruction: Specifically indicated for cases where preserving as much natural bone as possible and encouraging bone growth are the primary surgical goals.
