Cemented Stem (Polish Stem)

The Cemented Stem (Polish Stem) is a time-tested orthopedic implant engineered for definitive fixation in total hip replacement (THR). Designed specifically for use with bone cement, this stem is the ideal solution for patients with compromised bone density or wide medullary canals. The hallmark of this system is its high-gloss, mirror-polished surface, which is intentionally designed to facilitate the “taper-slip” principle—allowing for uniform load transfer and a stable interface within the polymethylmethacrylate (PMMA) cement mantle.

Manufactured from premium Medical Grade Stainless Steel, the stem provides the exceptional fatigue strength and mechanical rigidity required to support physiological loads over the long term. Its optimized geometry ensures a consistent cement mantle, which is critical for reducing stress concentrations and preventing early implant failure. By minimizing friction at the stem-cement interface, the polished design significantly reduces the risk of cement abrasion and subsequent osteolysis, ensuring high clinical survivorship.

Key Features & Benefits

• Mirror-Polished Finish: The ultra-smooth surface treatment is engineered to prevent cement-implant bonding, allowing for controlled subsidence that keeps the cement mantle in compression for maximum stability.

• High-Fatigue Stainless Steel: Built from orthopedic-grade alloys to provide superior resistance to the repetitive mechanical stresses of daily activity and weight-bearing.

• Anatomical Geometry: Features a refined taper and proximal-to-distal transition that supports accurate alignment and predictable seating within the femoral canal.

• Optimal Cement Mantle Formation: Specifically contoured to ensure a uniform circumferential thickness of bone cement, which is essential for protecting the femoral cortex and preventing loosening.

• Proven Clinical Longevity: Backed by decades of successful clinical data, making it a reliable and cost-effective choice for primary hip reconstruction.

Primary Clinical Applications

• Geriatric Total Hip Arthroplasty: The gold standard for elderly patients with osteoporotic bone (Dorr Type C), where immediate weight-bearing and stable mechanical fixation are required.

• Post-Traumatic Hip Reconstruction: Provides a dependable solution for patients undergoing hip replacement following complex femoral neck or intertrochanteric fractures.

• Dorr Type C Femoral Morphology: Specifically indicated for patients with “stovepipe” femurs where the bone quality is insufficient for a biological press-fit implant.

• Primary THR for Low-Demand Patients: Offers a stable and durable outcome for patients focused on pain relief and restoring moderate functional mobility.
