About Dynamic Hip Screw

Advin Health Care provides the Dynamic Hip Screw with precise engineering to ensure effective fracture stabilization. Its sliding lag screw allows dynamic compression of the fracture, promoting faster healing and maintaining proper alignment of the proximal femur. The DHS is compatible with standard cortical screws for secure fixation to the femoral shaft. It is widely used in open reduction and internal fixation (ORIF) procedures, facilitating early mobilization and functional recovery. The durable design minimizes soft tissue irritation and enhances postoperative patient comfort.

Advanced Features:

Sliding lag screw for controlled dynamic compression
Compatible with 4.5mm and 6.5mm cortical screws
Provides rigid fixation for intertrochanteric and subtrochanteric fractures
Low-profile design to reduce soft tissue irritation
Suitable for trauma and post-traumatic proximal femur fractures

Precision Engineering and Material Quality

Constructed from stainless steel or titanium alloys, the Dynamic Hip Screw provides high tensile strength and durability combined with a polished, corrosion-resistant surface. The anatomically contoured design and precision threading ensure accurate fit and enhanced stability during fixation.

Optimized for Surgical Efficiency

Designed to work seamlessly with standard DHS instrumentation, the lag screw incorporates a typical 135 angulation. Available in multiple plate hole options and screw sizes (50mm to 120mm), this implant supports real-time manual operation, simplifying both implantation and intraoperative handling for orthopedic surgeons.

Safety, Sterility, and Shelf Life Assurance

Pre-sterilized via ETO or gamma radiation methods, the DHS can be supplied as a single-use sterile product or reusable type. Each implant is CE marked and manufactured under ISO 13485 standards, with a shelf life of up to five years when stored in a dry, sterile environment.

FAQ's of Dynamic Hip Screw:

Q: How is the dynamic hip screw surgically implanted to treat femoral fractures?

A: The Dynamic Hip Screw is implanted through manual surgical procedures, using standard DHS instrumentation sets. After accurately positioning the anatomically contoured plate and lag screw at a typical 135 angle, the device stabilizes the proximal femur fracture effectively during real-time operation.

Q: What are the available options for plate holes and screw sizes in this DHS system?

A: This DHS system provides 2, 3, or 4 plate holes and screw lengths typically ranging from 50mm to 120mm, enabling orthopedic surgeons to match specific patient anatomical needs for optimal bone stabilization.

Q: When should a dynamic hip screw be used instead of other orthopedic implants?

A: A dynamic hip screw is recommended primarily for the fixation of intertrochanteric and subtrochanteric femoral fractures in adult patients, offering anatomical accuracy and stability for moderate to complex fracture patterns.

Q: Where should the pre-sterilized DHS implants be stored before use?

A: Pre-sterilized DHS implants must be stored in a clean, dry, sterile environment to maintain the integrity of the device and ensure patient safety until surgical use.

Q: What benefits does the polished metallic surface of the DHS provide?

A: The polished metallic surface offers enhanced corrosion resistance and improved compatibility with bodily tissues, reducing the risk of implant-related complications and supporting long-term durability.

Q: What is the shelf life of the sterile Dynamic Hip Screw and what are the recommended storage conditions?

A: Sterile Dynamic Hip Screws have a shelf life of up to five years when kept sealed in their original packaging and stored in a dry, sterile environment as per manufacturer instructions.

Q: How does this DHS meet international standards for quality and safety?

A: The Dynamic Hip Screw is CE marked and manufactured under ISO 13485 standards, ensuring global compliance for reliability, safety, and consistent product performance in orthopedic surgical applications.
