A fenestrated axial screw is an advanced orthopedic/spinal fixation screw designed with multiple small holes (fenestrations) along the shaft, enabling the controlled delivery of bone cement (such as PMMA) through the screw into the surrounding bone. This feature significantly enhances screw fixation strength and pull-out resistance, particularly in osteoporotic or compromised bone conditions.

The screw is typically inserted in a standard manner, after which bone cement is injected through a cannulated core, exiting via the fenestrations to create a cement-bone interface that improves anchorage and stability. This makes it highly effective in cases where conventional screws may not achieve sufficient fixation.

Manufactured from medical-grade titanium alloy, fenestrated axial screws offer high mechanical strength, corrosion resistance, and excellent biocompatibility. The design ensures uniform cement वितरण and controlled flow, reducing the risk of leakage while maximizing fixation.

These screws are widely used in spinal fixation procedures, trauma cases, and revision surgeries, especially in patients with osteoporosis, poor bone quality, or complex instability, where enhanced fixation is critical for successful outcomes.
