AI Overview
, this plate provides, at minimum, two proximal legs for secure, stable fixation in the radial shaft, reducing the risk of subsidence, particularly in osteoporotic bone.
Key Aspects of the PI Locking Plate System:
- Design & Application: Specifically designed for dorsal approach fixation, allowing for secure handling of comminuted intra-articular fractures (AO type C3) and dorsally displaced fractures.
- Biomechanical Stability: The double-row distal screw configuration and two-leg proximal design offer superior support to the articular surface.
- Low Profile: Most systems utilize low-profile, pre-contoured titanium, which helps minimize irritation in the dorsal area.
- Complications: While providing high stability, the primary concern is potential dorsal tendon irritation or rupture, which often necessitates planned implant removal 4 to 6 months post-surgery.
Alternatives and Comparisons:
- Volar Locking Plates: Generally considered the standard of care with lower complication rates compared to dorsal, though pi-plates are superior for specific dorsal comminution cases.
- Percutaneous Pinning: Used for less complex fractures; PI locking plates offer superior stability in complex fractures.
