Locking Screws (Proximal/Distal, Half-Threaded): Enhancing Stability in Femoral Fracture Fixation

Locking Screws (Proximal/Distal, Half-Threaded) are crucial components in orthopedic surgery, particularly for procedures involving bone fixation plates or nails used to treat femur fractures. These specialized screws offer several advantages for optimal fracture healing:

• Proximal and Distal Variations: Locking screws come in specific variations for placement within the femur. Proximal screws are designed for the upper end of the femur near the hip joint, while distal screws are used for the lower end near the knee. This ensures proper fit and functionality based on the anatomical location.
• Half-Threaded Design: Unlike fully threaded screws, these locking screws have threads along only half their length. This allows for secure purchase within the bone cortex (outer layer) while leaving the remaining half of the screw smooth. The smooth shank allows the screw to slide within the locking holes of the plate or nail, enabling compression and stability at the fracture site.
• Enhanced Fixation with Locking Plates or Nails: Locking screws are specifically designed to work in conjunction with bone fixation plates or nails that contain corresponding locking holes. When inserted through the plate or nail hole and into the bone, the smooth shank locks the screw within the plate/nail, preventing loosening and ensuring strong fixation of the fracture fragments.

Applications in Femoral Fracture Fixation:

Locking Screws (Proximal/Distal, Half-Threaded) are widely used in various surgical procedures for femoral fractures, including:

• Fixation with locking bone plates for complex fractures
• Minimally invasive surgery (MIS) techniques using femoral interlocking nails
• Revision surgery for fractures with hardware failure or non-union

Important Considerations:

Locking Screws (Proximal/Distal, Half-Threaded) are valuable tools for orthopedic surgeons, but their use requires proper surgical training and knowledge of specific fracture fixation techniques. Consulting with a qualified orthopedic surgeon is crucial to determine the most appropriate implant selection and surgical approach for your individual case. Here are some additional factors to consider:

• Type and severity of the femoral fracture
• Chosen method of fracture fixation (plate or nail)
• Patient’s overall health and medical history

Additional Notes:

• Locking screws come in various sizes, thread diameters, and lengths to accommodate different bone sizes, fracture patterns, and specific implant systems.
• The material of locking screws is typically stainless steel or titanium.
