DHS/DCS Screw 12.5mm X 70mm With Compression Screw SS316L Orthopedic

The Orthopedic DHS/DCS Screw 12.5mm x 70mm with Compression Screw SS316L is an orthopedic implant used in Dynamic Hip Screw (DHS) or Dynamic Condylar Screw (DCS) systems. These systems are commonly used for the fixation of intertrochanteric fractures, proximal femur fractures, and supracondylar fractures. Here’s a breakdown of the features and specifications:

Specifications Breakdown:
12.5mm Diameter: This screw has a diameter of 12.5 millimeters, which is relatively large compared to typical screws used for smaller bone fractures. The larger diameter ensures a strong, stable fixation in the femur or other bones that require greater load-bearing capacity. The screw’s size is designed to handle the stresses of weight-bearing activities, ensuring that it remains securely in place during the healing process.

70mm Length: The screw measures 70 millimeters in length. The length of the screw is important for providing sufficient engagement with the bone to ensure that the fracture is stabilized effectively. In the case of fractures in the femur or similar bones, this length helps to secure the fracture fragments and promote healing. The 70mm length is commonly chosen for fractures in the proximal femur or areas requiring a moderate depth of screw insertion.

Compression Screw: The compression screw is a key feature of the DHS/DCS system. The compression screw is used to apply compression across the fracture site, helping to stabilize the fractured bone and promote the healing process. Compression is essential to maintaining alignment of the bone fragments during healing, and the compression screw ensures that the fracture is kept in a position that promotes union and reduces the risk of nonunion or malunion.

SS316L (Stainless Steel 316L): The screw is made from SS316L stainless steel, a high-grade medical alloy known for its excellent corrosion resistance, biocompatibility, and strength. The “L” in SS316L stands for low carbon, which improves the material’s resistance to corrosion, making it particularly useful for long-term implantation in the body. SS316L is durable and can withstand the biomechanical forces exerted on the bone during the healing process.

Typical Uses:
The 12.5mm x 70mm DHS/DCS Screw with a compression screw is primarily used in:

Fracture Fixation: Primarily for intertrochanteric or subtrochanteric fractures of the femur, as well as fractures in the proximal femur or distal femur. The screw provides compression at the fracture site to stabilize and promote bone healing.
Dynamic Hip Screw (DHS) System: A DHS system is used for hip fractures, especially in elderly patients with hip fractures. The compression screw helps maintain alignment by applying pressure across the fracture site.
Dynamic Condylar Screw (DCS) System: A DCS system is used for fractures that involve the femoral condyles, often used in situations with supracondylar fractures of the femur.
Osteotomies: The screw can also be used in procedures where bones are cut and realigned, providing compression and stability during the healing process.
Advantages of DHS/DCS Compression Screws:
Compression Mechanism: The compression screw is designed to apply compression across the fracture site. This compression helps bring the bone fragments together, which is critical for the healing process. It improves the chances of a successful union by maintaining alignment and stability.
High Strength and Stability: The 12.5mm diameter provides high strength and stability, allowing the screw to support the mechanical load placed on the bone during weight-bearing activities. This is important for fractures that need to withstand high stress during the healing process.
Biocompatibility: SS316L stainless steel is highly biocompatible, minimizing the risk of adverse reactions when the screw is implanted in the body. It is a widely used material in orthopedic implants due to its ability to integrate well with the body and reduce the likelihood of infection or complications.
Corrosion Resistance: SS316L is resistant to corrosion, making it ideal for long-term implantation, as it ensures the screw remains functional and intact over time without degrading or weakening.
Durability: The SS316L material provides excellent durability, ensuring that the screw remains intact during the healing process and can withstand the biomechanical forces exerted on it by the body.
Ease of Insertion: The screw is designed for efficient placement in the bone, with the compression screw mechanism simplifying the process of securing the fracture.
Conclusion:
The 12.5mm x 70mm Orthopedic DHS/DCS Screw with Compression Screw made of SS316L is a critical implant for the stabilization of fractures, particularly in the femur and other large bones. The 12.5mm diameter ensures a strong, durable fixation, while the 70mm length provides sufficient depth to engage the bone for optimal stability. The compression screw allows for effective compression of the fracture site, promoting alignment and aiding in the healing process. The SS316L stainless steel material offers excellent corrosion resistance and biocompatibility, making it a safe and long-lasting option for fracture fixation. This screw is an essential tool for orthopedic surgeons performing procedures to treat hip fractures, femoral fractures, or fractures in other weight-bearing bones.
