Application and Advantages of Cannulated Screw for Medical Orthopedic Implants

In modern orthopedic surgery, the choice of implant is crucial to the success of fracture treatment. Cannulated Screw, as a commonly used orthopedic implant, have been widely used in clinical practice due to their unique design and excellent performance. In this article, we will discuss the application of Cannulated Screw in orthopedic surgery and their advantages.

Cannulated Screw are screws with a cavity in the center, usually made of materials such as titanium alloy or stainless steel. This design not only reduces the weight of the implant, but also allows for more precise fixation by passing a guide pin or wire inside the screw. The head of the Cannulated Screw usually has self-tapping threads that can be easily screwed into the bone to provide strong fixation.

Application of Cannulated Screw

Cannulated Screw are widely used in orthopedic surgery, especially for femoral neck fracture and patella fracture. Neck of femur fracture mostly occurs in the elderly and children, for children, Cannulated Screw can avoid the damage to the epiphysis and reduce the postoperative complications. Cannulated Screw combined with tension band fixation is often used for patella fracture to realize anatomical repositioning and early functional exercise.

Taking patellar fracture as an example, the fracture site is usually fixed temporarily with Kirschner's pin, and then under the fluoroscopic view of C-arm machine, the Cannulated Screw is screwed along the guide pin to make sure that the threads pass through the fracture line completely. This method can effectively reduce surgical trauma and accelerate the patient's postoperative recovery.

Advantages of Cannulated Screw

a) Biomechanical Advantages: The design of the Cannulated Screw allows it to provide uniform compression at the fracture site, helping to promote fracture healing. At the same time, its triangular distribution of structural strength provides stable fixation and prevents fracture redisplacement.

b) Minimally invasive surgery: Cannulated Screw can usually be implanted through a small incision, which reduces surgical trauma and post-operative pain, and accelerates patient recovery.

c) Reduced complications: Compared with traditional implants, Cannulated Screw fixation can reduce the incidence of complications such as fracture non-union, malunion and infection. Especially in pediatric femoral neck fracture, Cannulated Screw can effectively avoid damage to the epiphysis and reduce serious complications such as femoral head necrosis.

d) Early postoperative functional exercise: As the Cannulated Screw provides a strong fixation effect, patients can perform functional exercise in the early postoperative period, which can accelerate the recovery of joint function and reduce the occurrence of joint stiffness and muscle atrophy.

Conclusion.

As an important orthopedic implant, Cannulated Screw plays an important role in fracture treatment with its unique biomechanical advantages and minimally invasive characteristics. Through precise fixation and minimally invasive surgery, Cannulated Screw not only improves the fracture healing rate, but also reduces the incidence of postoperative complications, providing patients with better treatment results and quality of life. With the continuous development of material science and surgical techniques, the application of Cannulated Screw in orthopedics will have a broader future!
