The Wyvern Hip Replacement Pack by Signature Orthopaedics offers a comprehensive solution for orthopedic surgeons specializing in hip replacement surgeries. This modular system is meticulously designed to address a wide range of hip joint conditions, providing versatility and precision in surgical outcomes.

Key Components

• Modular Femoral Stems: Available in various sizes and materials, including stainless steel and optional hydroxyapatite coating, to accommodate different patient anatomies and fixation needs.
• Acetabular Cups: Featuring a 10° posterior wall and textured surface, made from ultra-high molecular weight polyethylene (UHDMWPE), with diameters ranging from 28mm to 56mm.
• Femoral Heads: Offered in multiple diameters and neck length offsets, constructed from materials such as cobalt chrome, high nitrogen stainless steel, and BIOLOX® delta ceramic.
• Stem Centralizers and Bone Cement Restrictors: Made from UHDMWPE, provided in sterile packs.
• Instrument Sets: Includes essential tools like rasp stem introducers, prosthesis impactors, and reamers, supplied non-sterile for pre-surgical sterilization.

Features and Benefits

• Versatile Modular System: Allows for tailored combinations of femoral stems, heads, and acetabular components to match specific surgical requirements.
• Biological Ingrowth and Cemented Fixation Options: Femoral components designed for both biological ingrowth and cemented fixation, enhancing adaptability.
• Advanced Material Composition: Utilizes high-grade materials such as Ti-6Al-4V alloy and BIOLOX® delta ceramic for durability and biocompatibility.
• Secure Taper Connections: Employs a 12/14 Euro taper for modular heads, with taper sleeves for secure attachment.

Packaging and Sterilization

All implants are individually sterile packed, using gamma radiation or ethylene oxide sterilization, ensuring safety and readiness for immediate use. Instruments require sterilization before use, recommended through a pre-vacuum cycle at 132°C.

Indications and Contraindications

The system is intended for patients with:

• Non-inflammatory degenerative joint diseases
• Inflammatory arthritis
• Hip joint trauma or previous surgical failure

Contraindications include conditions like osteoporosis and active infections. The use of components from other manufacturers is strongly discouraged to maintain system integrity.

Precautions

• MR Environment: Not evaluated for use in magnetic resonance environments.
• Component Inspection: Non-threaded components should be checked for damage before use.
• Resterilization: Not recommended for implants, particularly if packaging integrity is compromised.

Postoperative Considerations

Proper cleaning and maintenance of instruments are crucial, with postoperative care involving physical therapy and regular follow-ups to monitor implant performance and patient recovery.

The Wyvern Hip Replacement Pack embodies Signature Orthopaedics' commitment to quality and innovation, offering a reliable and adaptable solution for successful hip replacement surgeries.
