6.5mm Cannulated Headless Screw | Orthopedic Trauma Implants

Clinical Indications in Orthopedic Trauma The 6.5mm cannulated headless screw is indicated for large fragment intra-articular trauma reconstruction, osteotomies, non-union stabilization, and high-load joint arthrodesis:

  • Hindfoot & Ankle Arthrodesis: Subtalar joint fusion, tibiotalar (ankle) arthrodesis, and triple arthrodesis procedures where protruding hardware causes painful subcutaneous soft-tissue prominence.

  • Femoral Condyle Coronal Shear Fractures: Hoffa fractures (AO/OTA 33-B3) of the distal femur requiring anterior-to-posterior or posterior-to-anterior subchondral headless compression.

  • Tibial Plateau Fractures: Split intra-articular coronal or sagittal fractures of the medial or lateral tibial condyles (Schatzker Type I, II, and IV) requiring subchondral interfragmentary lag compression.

  • Talus & Calcaneus Trauma: Displaced fractures of the talar body/neck and large intra-articular calcaneus shear splits.

  • Pelvic & Acetabular Column Fixation: Subchondral lag fixation across posterior wall/column acetabular fragments where screw heads would obstruct joint kinematics.

  • Major Joint Osteotomies: Supracondylar femoral or tibial corrective osteotomies requiring high-yield internal compression.

Product Featured

Variable Pitch High-Yield Compression

Precision-engineered with a wider thread pitch at the leading distal tip and a finer thread pitch at the trailing proximal end. Each full revolution draws the distal fragment closer to the proximal fragment, producing sustained axial interfragmentary compression across fracture or fusion planes without relying on an external screw head.

True Headless Subchondral Profile

Countersinks entirely subchondral or flush with the articular cartilage, maintaining smooth joint articulation, preventing joint surface conflict, and eliminating friction against overlying soft-tissue envelopes and tendons in thin subcutaneous areas.

Fluoroscopy-Guided Percutaneous Precision

A calibrated central longitudinal cannula permits guided delivery over a 2.0 mm – 2.4 mm guide wire under intraoperative C-arm fluoroscopy, enabling minimally invasive surgery (MIS), reducing blood loss, and preserving delicate periosteal vascularity.

Self-Drilling & Self-Tapping Flutes

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

Anti-Cam-Out High-Torque Recess

Broached with a precision StarDrive (T25/T30) or 4.0 mm cannulated hexagonal recess that provides deep driver engagement, maximizing torque transmission and preventing driver slippage, cam-out, or drive stripping during deep countersinking.

Traceability

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