Bipolar Hip Prosthesis

This Bipolar Hip Prosthesis is designed for use in hemiarthroplasty procedures. Orthopedic surgeons use it to treat femoral neck fractures, avascular necrosis of the femoral head, and similar hip conditions. It works well in cases where partial hip replacement is the right clinical choice.

How the Bipolar Design Works

The implant uses a dual-bearing system. An inner femoral head moves inside a larger outer cup. As a result, motion spreads across two surfaces instead of one. This helps surgeons achieve a broader functional range of motion. In addition, it reduces the risk of acetabular erosion and protrusio acetabuli — two complications that can occur with standard unipolar hemiarthroplasty.

Key Features

• Dual-bearing bipolar design for better articulation and reduced acetabular wear
• Head sizes from 30mm to 60mm to fit a wide range of patient anatomies
• Fenestrated and Non-Fenestrated stem options for cemented and uncemented fixation
• Material options: premium-grade surgical stainless steel and titanium
• High-polish outer cup surface for smooth movement within the native acetabulum
• Tapered femoral stem with collar for stable intramedullary seating

Fenestrated vs. Non-Fenestrated Stems

The fenestrated stem has openings along its length. These openings allow bone or cement to integrate with the implant. Consequently, this option supports secure fixation and better osseointegration in suitable cases. The non-fenestrated stem, on the other hand, has a solid profile. Surgeons typically prefer it in cemented hemiarthroplasty, where bone cement provides primary fixation. Both stem types come in stainless steel and titanium. This gives surgical teams the flexibility they need based on patient needs and procedure type.

Material & Build Quality

Both material options meet the durability and biocompatibility standards that orthopedic implants require. Titanium offers a high strength-to-weight ratio. It also suits patients where metal sensitivity or long-term bone integration is a factor. Stainless steel, meanwhile, delivers proven mechanical performance and remains a trusted choice across orthopedic applications worldwide.

Clinical Indications

Surgeons use this hip implant in the following conditions:

• Displaced femoral neck fractures (subcapital and transcervical)
• Avascular necrosis (AVN) of the femoral head
• Pathological fractures of the femoral neck
• Cases where total hip replacement is not suitable

Available Sizes

The prosthesis comes in outer head diameters from 30mm to 60mm. This wide size range allows surgeons to match the implant closely to the patient’s native femoral head. As a result, they can achieve better joint fit and improved outcomes.

This Bipolar Hip Prosthesis suits hospitals, orthopedic surgery centers, surgical distributors, and procurement teams. Both fenestrated and non-fenestrated versions are available in stainless steel and titanium. Contact us for size availability and further product details.
