Cemented Stem (Polish Stem) | Un Cemented TI + HA Coated Stem | Un Cemented Porus Coated Stem

Description

Our comprehensive portfolio of Hip Replacement Stems provides orthopedic surgeons with a versatile range of fixation options to address diverse patient bone morphologies, age groups, and activity levels. Whether performing a primary Total Hip Replacement (THR) or a complex revision, these stems are engineered to restore joint biomechanics while ensuring a stable, long-lasting interface with the femoral canal.

We offer three distinct stem technologies, each manufactured from medical-grade alloys and precision-machined to ensure anatomical accuracy and mechanical integrity.

1. Cemented Stem (Polished Finish)

The Cemented Polished Stem is the gold standard for patients with compromised bone quality or wider femoral canals (Dorrs Type C). Manufactured from high-fatigue-strength Stainless Steel, its mirror-polished surface is specifically designed to work with bone cement.

• Key Advantage: The polished geometry facilitates a “taper-slip” mechanism, allowing for uniform load transfer to the cement mantle and reducing the risk of cement-mantle fracturing.

• Clinical Use: Highly recommended for geriatric trauma cases and patients with osteoporosis where immediate weight-bearing is required.

2. Uncemented TI + HA Coated Stem

Engineered for biological fixation, the Titanium (TI) + Hydroxyapatite (HA) Coated Stem is designed for the active patient. The titanium alloy core provides an elasticity modulus closer to natural bone, while the HA coating acts as a bioactive scaffold.

• Key Advantage: The HA coating stimulates rapid osseointegration, creating a chemical and mechanical bond between the bone and the implant for superior long-term stability.

• Clinical Use: Ideal for younger, active patients with good bone stock who require a “press-fit” solution.

3. Uncemented Porous Coated Stem

The Porous Coated Stem features a specialized surface architecture designed to facilitate mechanical bone ingrowth. The microscopic pores allow the patient’s natural bone to grow into the implant surface, creating a permanent, rigid fixation.

• Key Advantage: Provides exceptional primary stability through a high-friction coefficient at the time of insertion, followed by reliable secondary biological fixation.

• Clinical Use: Perfect for patients where robust mechanical interlocking is prioritized to prevent early micromotion and subsiding.

Key Features across the Range

• Orthopedic-Grade Materials: High-strength Stainless Steel or Titanium alloys ensure maximum biocompatibility and corrosion resistance.

• Precision Taper Machining: Standardized tapers ensure seamless compatibility with a wide range of modular femoral heads (SS, CoCr, or Ceramic).

• Anatomical Geometry: Optimized neck-shaft angles and distal tapering to prevent stress shielding and ensure a smooth surgical fit.

• Broad Size Range: Available in multiple sizes and offsets to precisely match the patient’s unique femoral anatomy.
