The LISS (Less Invasive Stabilization System) Distal Femoral Safety Lock Plate is specifically designed for internal fixation using minimally invasive surgical techniques. It combines angular stable fixation with soft tissue preservation, ensuring both mechanical stability and biological support for fracture healing.
Anatomically pre-contoured for the lateral distal femur, the plate eliminates the need for intraoperative bending and allows optimal fracture alignment. Its low-profile design accepts both 4.5 mm cortical screws and 5.0 mm locking screws, enabling hybrid fixation (locking and non-locking).
The angular stable locking mechanism creates a fixed-angle construct that provides excellent stability, particularly in osteoporotic or comminuted bone. Its compatibility with Minimally Invasive Percutaneous Osteosynthesis (MIPO) preserves the periosteal blood supply and soft tissue envelope, reducing infection risk and supporting faster healing. A distal cluster of multiple screw holes ensures strong metaphyseal fixation, even in short distal fragments, while the targeting jig enables accurate screw placement through small incisions.
Indications
- Distal femoral fractures, including supracondylar fractures (AO/OTA 33-A, 33-C), comminuted intra-articular fractures, and osteoporotic or pathologic fractures
- Periprosthetic fractures around total knee arthroplasty
- Nonunions or malunions of the distal femur
- Fractures in polytrauma patients where soft tissue preservation is critical
- Metaphyseal-diaphyseal junction fractures
- Open fractures where minimally invasive stabilization is preferred
