Micromed’s 3.5 mm diameter titanium cortical screw offers an excellent combination of stability, biocompatibility and reduced implant weight. It is ideal for precise fixation in cortical bone and is particularly suitable for demanding applications in orthopaedics and traumatology.
The titanium cortical screw (Ø 3.5 mm) represents a modern and high-performance solution for osteosynthesis. With a length range of 12 mm to 115 mm, it covers a wide range of indications and allows for precise adaptation to individual anatomical requirements. Titanium offers significant advantages over stainless steel in clinical use. Its excellent biocompatibility minimises the risk of adverse reactions, which is particularly important in sensitive patients. Furthermore, titanium is characterised by high corrosion resistance and very good osseointegration, thereby supporting stable and long-term anchorage in the bone. Another key advantage is titanium’s lower modulus of elasticity compared to stainless steel. This is closer to that of bone tissue, enabling a more physiological load distribution and reducing the risk of stress shielding. At the same time, the material’s high strength ensures reliable stability even under demanding load conditions.
The precisely engineered thread geometry of the 3.5 mm diameter cortical screw ensures secure anchorage in the cortical bone and facilitates controlled force transmission. It is ideally suited for use in plate osteosynthesis and is frequently employed in fractures of the radius, ulna, humerus and tibia. Typical applications include:
Fracture management in the upper and lower extremities Use in 3.5 mm plate systems Management of diaphyseal and metaphyseal fractures Applications with increased requirements for biocompatibility
For surgeons and operating theatre staff, the titanium cortical screw offers precise handling, a high degree of procedural reliability and dependable results in everyday clinical practice. micromed stands for consistent quality, well-thought-out design and practice-oriented implant solutions.
Comparison of titanium cortical screws with stainless steel cortical screws The choice between titanium and stainless steel cortical screws is a key factor in modern osteosynthesis. Both materials offer specific advantages that can be utilised in a targeted manner depending on the indication and clinical requirements. Titanium cortical screws are characterised by their excellent biocompatibility and are used in particular for sensitive patients or where there are heightened requirements for tissue compatibility. Titanium’s modulus of elasticity, which is lower than that of stainless steel, is closer to that of human bone, enabling a more physiological load distribution and reducing the risk of stress shielding. Furthermore, titanium promotes osseointegration and supports long-term stable anchorage within the bone. Stainless steel cortical screws, on the other hand, offer very high mechanical strength and have been a tried-and-tested standard in orthopaedics and traumatology for many years. They are particularly suitable for applications involving high loads and impress with their robustness and cost-effectiveness. Stainless steel implants enable reliable fixation and are well established in numerous standard indications. Advantages of titanium at a glance:
Very high biocompatibility Lower risk of adverse reactions Modulus of elasticity closer to that of bone (reduced stress shielding) Very good corrosion resistance Promotes osseointegration
An overview of the advantages of stainless steel:
High mechanical strength A tried-and-tested material in clinical practice High stability in high-load applications Cost-effective Reliable and reproducible results
In clinical practice, the decision between titanium and stainless steel cortical screws depends on various factors, including the indication, load-bearing conditions, patient profile and surgical preference. micromed offers both variants in consistently high quality to provide surgeons and operating theatre staff with the optimal solution for every application.
