Clinical Indications in Orthopedic Trauma The 4.9mm interlocking screw is indicated for large long-bone fracture stabilization managed with intramedullary devices:
-
Femoral Shaft Fractures: Transverse, spiral, oblique, and comminuted midshaft femur fractures (Winquist-Hansen Type I–IV) treated with reamed or unreamed femoral nails.
-
Retrograde Femoral Fixation: Supracondylar and distal femoral metaphyseal fractures requiring distal transverse and condylar interlocking bolts.
-
Tibial Diaphyseal Fractures: High-energy tibia shaft fractures and segmental fractures stabilized with antegrade tibial intramedullary nails.
-
Periprosthetic & Subtrochanteric Trauma: Distal interlocking stabilization for long cephalomedullary constructs in subtrochanteric and extended shaft fractures.
-
Fracture Dynamization & Non-Unions: Controlled dynamization procedures utilizing the dynamic locking oval slot to convert static constructs into axial compression modes, promoting callus formation.
