3.9mm Interlocking Screw | Orthopedic Trauma Implants

Clinical Indications in Orthopedic Trauma The 3.9mm interlocking screw is indicated for transverse, oblique, and comminuted fracture management stabilized with intramedullary devices:

  • Tibial Shaft Fractures: Proximal, middle, and distal third diaphyseal tibia fractures managed with reamed or unreamed interlocking tibial nails.

  • Humeral Diaphyseal Trauma: Antegrade and retrograde humeral nailing for midshaft humerus fractures, pathological lesions, and impending humeral fractures.

  • Metaphyseal Tibial Extensions: Distal pilon-extension fractures and proximal extra-articular tibia fractures requiring multi-planar distal/proximal locking configurations.

  • Non-Unions & Malunions: Revision osteosynthesis and dynamization procedures using dynamic locking slots to induce axial dynamization and secondary callus formation.

  • Pathological & Periprosthetic Fixation: Prophylactic and post-fracture stabilization of osteolytic long-bone lesions requiring stable load-sharing constructs.

Product Featured

Rotational & Axial Load Bearing

Secures both static and dynamic locking apertures within the nail, converting the implant into a load-sharing internal splint that neutralizes cyclic bending, shearing, and torsional forces.

Enhanced Cross-Sectional Shear Resistance

Engineered with an enlarged core-to-thread ratio to resist high transverse shearing stresses applied by the intramedullary nail wall during early patient rehabilitation.

Self-Tapping Blunt-Tapered Tip

Features dual cutting flutes for fast cutting across near and far cortices while terminating in a rounded tip to reduce irritation of periosteal soft tissues and adjacent neurovascular bundles on the far cortex.

Low-Profile Hemispherical Head

Contoured head geometry countersinks cleanly against the cortical surface to minimize soft-tissue impingement, bursitis, and prominent hardware discomfort in thin-envelope anatomical sites (e.g., distal tibia and proximal humerus).

High-Torque Drive Interface

Available in deep StarDrive (T15/T20) or 3.5 mm hexagonal recess profiles to ensure positive driver coupling and eliminate cam-out, stripping, or driver jamming through distal targeting jigs and radiolucent drill guides.

Traceability

High-precision laser etching on the screw head displays diameter, length, and lot numbers for 100% operating room tracking and implant registry safety.
