5.0mm Cannulated Headless Screw | Orthopedic Trauma Implants

Clinical Indications in Orthopedic Trauma The 5.0mm cannulated headless screw is indicated for articular trauma reconstruction, osteotomies, non-union stabilization, and joint arthrodesis across medium-to-large skeletal structures:

  • Hindfoot & Tarsal Trauma: Displaced fractures of the talus (neck and body), intra-articular calcaneal fractures, and large cuboid/navicular split fractures.

  • Midfoot & Hindfoot Arthrodesis: Subtalar joint fusion, talonavicular arthrodesis, and calcaneocuboid joint fusion where protruding screw heads would cause painful subcutaneous or intra-articular impingement.

  • Foot & Ankle Osteotomies: Calcaneal sliding osteotomies, Dwyer osteotomies, and corrective midfoot re-alignments requiring high axial compression.

  • Malleolar & Tibial Pilon Fragments: Large Chaput, Wagstaffe, or Volkmann’s (posterior malleolus) articular fragments requiring rigid lag compression without bulky hardware under thin skin envelopes.

  • Knee & Patellar Trauma: Articular split coronal shear fractures of the distal femoral condyles (Hoffa fractures) and coronal patellar fractures.

  • Periprosthetic & Acetabular Augmentation: Supplementary articular fragment lag fixation where conventional screw heads would interfere with joint motion or implant seating.

Product Featured

Differential Variable Pitch Compression

Designed with a wider, coarser thread pitch at the leading distal end and a tighter, finer pitch at the trailing proximal end. Each full revolution draws the distal fragment closer to the proximal fragment, generating uniform, high-yield axial interfragmentary compression across the fracture line without relying on an external screw head.

True Headless Subchondral Profile

Countersinks entirely subchondral or flush with the articular cartilage, preserving smooth articular joint kinematics, preventing mechanical conflict with opposing articular surfaces, and eliminating friction or attrition of overlying tendons and soft-tissue envelopes.

Percutaneous Cannulated Precision

The continuous central longitudinal cannula allows insertion over a 1.4 mm – 1.6 mm calibrated guide wire under intraoperative C-arm fluoroscopy, enabling minimally invasive percutaneous surgery (MIS), reducing blood loss, and safeguarding local periosteal vascularity.

Dual Self-Drilling & Self-Tapping Geometry

Precision reverse-cutting flutes on both the leading and trailing threads clear bone chips during insertion, lowering peak cutting torque, minimizing micro-fracture risks, and removing the need for a separate bone tap in dense subchondral or cortical bone.

Anti-Cam-Out High-Torque Recess

Deep-broached StarDrive (T20) or 3.5 mm cannulated hexagonal drive recess provides deep driver engagement, maximizing torque transmission and preventing driver slippage, cam-out, or head deformation during high-torque subchondral countersinking.

Traceability

High-precision permanent laser markings on the unthreaded central shank display diameter, length, and batch lot numbers for 100% OR tracking and regulatory compliance.
