4.0mm Cancellous cannulated screw | Orthopedic Trauma Implants

Clinical Indications in Orthopedic Trauma The 4.0mm self-tapping cancellous cannulated screw is indicated for fracture management, reconstruction, and arthrodesis in small to medium-sized bones:

Ankle & Pilon Fractures: Medial and lateral malleolar fracture fixation, distal anterior tibial margin (Tillaux/Chaput) fragments, and Volkmann’s posterior rim fixation.

Foot & Tarsal Trauma: Talus neck and body fractures, intra-articular calcaneus fractures, navicular fractures, and Lisfranc tarsometatarsal arthrodesis.

Pelvis & Acetabular Fixation: Iliac wing compression, pediatric pelvic trauma, and peri-articular lag fixation.

Knee & Patellar Trauma: Patellar fractures (tension band wiring augmentation or direct lag screws), coronal shear fractures of the distal femur and proximal tibia.

Wrist & Elbow Fixation: Radial head and neck fractures, olecranon osteotomies, coronoid process fixation, and carpal scaphoid stabilization.

Pediatric & Small Stature Trauma: Slipped capital femoral epiphysis (SCFE) in small frames or pediatric metaphyseal fracture compression.

Percutaneous Guide-Wire Insertion

The smooth internal longitudinal cannula allows accurate delivery over a 1.25 mm guide wire under fluoroscopic C-arm guidance, minimizing soft-tissue disruption, reducing surgical exposure, and safeguarding periosteal vascularity.

Deep Cancellous Thread Architecture

Engineered with an enlarged outer-to-core diameter ratio and aggressive thread pitch to maximize surface contact area and purchase in soft, porous, or osteopenic cancellous bone, significantly increasing pull-out strength.

Interfragmentary Lag Compression

The partially threaded configuration (with a smooth proximal shaft) creates controlled interfragmentary compression across fracture planes as the threads bite the distal fragment and the hemispherical head seats against the near cortex or washer.

Efficient Self-Tapping & Self-Drilling Flutes

Sharp distal reverse-cutting flutes clear dense bone debris during insertion, reducing driving torque, operative steps, and the risk of thermal osteonecrosis.

Low-Profile Head with Washer Compatibility

Hemispherical head profile countersinks neatly into bone margins; pairs with dedicated spherical washers to distribute compressive loads evenly across thin cortical bone envelopes and prevent head sinkage.

Anti-Cam-Out Drive Recess

Precision 2.5 mm hexagonal or StarDrive recess ensures positive engagement under high compression loads, preventing driver slippage and head deformation during final tight seating.

Traceability

Permanent high-resolution laser marking denoting diameter, length, and manufacturing lot code on each individual piece.
