A Brief Guide to Orthopedic Screw Types and Applications

Orthopedic screws are fundamental fixation implants used to stabilize bone fragments, maintain alignment, and support healing in fracture management. From distal radius fractures to hip fixation procedures, selecting the appropriate orthopedic screw types plays an important role in achieving stable fixation and supporting clinical outcomes. Selection depends on factors such as bone quality, fracture pattern, anatomical location, and surgical technique.  In this article, we’ll explore five major types of orthopedic screws, explain their design features, and highlight their role in modern fracture fixation systems, helping you make an informed decision. 

1. Cortical Screws: Precision for Dense Bone

Cortical screws are designed for fixation in hard cortical bone and feature a high core-to-outer diameter ratio that provides the rigidity needed for stable fixation. Their shallow, closely spaced thread profile supports strong engagement in dense bone, making them suitable for procedures requiring precise stabilization. Commonly manufactured in stainless steel and titanium alloys, cortical screws are available in multiple diameters to suit different anatomical and procedural requirements, with self-tapping variants helping streamline insertion during surgery.

These screws are commonly used in the fixation of diaphyseal fractures involving long bones such as the femur, tibia, and humerus. They are often used with plate systems to help maintain fracture alignment and support fixation in load-bearing regions.

2. Cancellous Screws: Secure Fixation for Soft Bone

Cancellous screws are designed for fixation in spongy trabecular bone and are commonly used in anatomical regions where cortical bone is thinner or limited. Their deep, widely spaced threads are intended to improve purchase in softer bone structures, supporting stable fixation where bone density is lower. Depending on procedural requirements, cancellous screws may be available in partially or fully threaded designs and are commonly manufactured in stainless steel and titanium alloys for strength and biocompatibility. Self-tapping options may also be used to support surgical efficiency in selected procedures.

They are commonly used in metaphyseal and epiphyseal fractures, including proximal humerus fractures and injuries near joint surfaces. Cancellous screws are particularly valuable in osteoporotic bone, where improved purchase may help support fixation stability. In some cases, surgeons combine cancellous and cortical screws in hybrid constructs to address variations in bone density within the same fracture.

3. Cannulated Screws: Guide-Wire Precision for Minimally Invasive Surgery

Cannulated screws are designed with a hollow core that accommodates a guide wire, supporting controlled implant placement during orthopedic procedures. This feature enables more precise positioning and facilitates percutaneous insertion, helping minimise soft tissue disruption during minimally invasive approaches. Depending on fixation requirements, cannulated screws may be available in cortical or cancellous thread configurations, as well as self-tapping variants and multiple diameters to accommodate different anatomical locations and bone densities.

These screws are commonly used in procedures requiring accurate fixation, including femoral neck, wrist, and ankle fracture management. They are also used in selected ligament reconstruction procedures where guided placement supports stable fixation. Their compatibility with minimally invasive techniques has contributed to their widespread use in modern orthopedic surgery.

4. Lag Screws: Compression for Fracture Stabilisation

Lag screws are designed to generate interfragmentary compression by engaging the far bone fragment while allowing smooth passage through the near fragment. This mechanism helps draw fractured bone segments together, supporting fracture stability and bone healing. Depending on the fixation strategy, lag screws may be used independently or incorporated into broader fixation constructs to enhance stabilisation.

They are commonly used in fractures where compression plays an important role in supporting bone union, including intertrochanteric hip fractures and tibial plateau fractures. Lag screw principles are also incorporated into systems such as cephalomedullary nails and dynamic hip screw constructs to support fracture fixation.

5. Headless Herbert Screws: Low-Profile Fixation for Small Bones

Headless Herbert screws, also known as headless compression screws, are cannulated compression screws designed with differential threading at both ends to generate controlled compression while remaining flush with the bone surface. Their headless profile helps minimise soft tissue irritation after implantation, while the cannulated structure supports guide-wire-assisted placement for improved positioning accuracy. Different thread pitches at each end of the screw create compression as the implant advances, helping maintain stable fixation across the fracture site.

These screws are commonly used in small bone fractures involving the hand, wrist, and foot, particularly scaphoid and metacarpal fractures. They are also used in selected foot and ankle arthrodesis procedures where stable fixation is required without prominent hardware.

How Orthopedic Screw Design Supports Modern Fracture Fixation

Advances in orthopedic screw design have improved the way fractures are stabilized, allowing surgeons to adapt fixation strategies based on fracture type, bone quality, and anatomical requirements. Modern fixation systems increasingly combine precision engineering and specialized implant designs to support stable fixation across complex clinical scenarios. Key innovations shaping orthopedic screw applications include:

Locking Plate Systems: Threaded screw heads lock into the plate to create fixed-angle constructs, helping maintain stability in osteoporotic or comminuted fractures where conventional fixation may be less reliable.

3D Printing: Patient-specific implant planning and customized fixation strategies are increasingly being explored for anatomically complex fractures.

Robotic-Assisted Fixation: Emerging robotic technologies are helping improve implant positioning and surgical precision in selected orthopedic procedures, particularly in complex reconstruction cases.

Material selection also continues to influence implant performance. Titanium alloys are widely used for their strength, corrosion resistance, and biocompatibility, while stainless steel remains a reliable option in many trauma applications. Thread configuration, diameter, and self-tapping features further help surgeons adapt fixation to procedural needs.

Final Word 

Orthopedic screws remain central to modern fracture fixation, with different designs supporting specific clinical needs across trauma and reconstructive procedures. Selecting the appropriate orthopedic screws along with locking plates based on procedural requirements and bone characteristics plays an important role in supporting stable fixation and long-term performance. To ensure quality and biocompatibility, choose a dependable orthopedic implant supplier. With their broad portfolio of orthopedic screws available in different materials, designs, and sizes, you can address varied fixation requirements across clinical settings.
