Herbert Screws Instruments Set

The Herbert Screw Instrument Set is a high-precision toolkit designed for the fixation of scaphoid and small bone fractures. Optimized for headless cannulated compression screws, this 316L stainless steel set includes specialized jigs, cannulated drills, and guide wires. It is the clinical standard for hand and foot surgeons requiring internal compression without hardware protrusion, ensuring maximum joint mobility and stable anatomical healing.

The Herbert Screw Instrument Set is a specialized orthopedic kit designed for the fixation of small bone fractures, non-unions, and osteotomies, most notably scaphoid fractures in the wrist. The Herbert screw is unique because it is a headless, cannulated compression screw with differential thread pitches that allow for internal compression without leaving hardware protruding from the articular surface.

Crafted from High-Grade 316L Stainless Steel or Titanium, this set provides the delicate, high-precision tools required for hand and foot surgery where anatomical space is extremely limited.

Core Components & Technical Utility

Instrument Surgical Function
Cannulated Drill Bits Precision-engineered to slide over a guide wire for perfectly centered bone tunnels.
Threaded Guide Wires Used for initial fracture reduction and to establish the exact trajectory of the screw.
Herbert Screw Inserter A specialized screwdriver designed to engage the headless drive mechanism of the screw.
Parallel Guide / Jig Ensures that the guide wire is placed perfectly perpendicular to the fracture line for maximum compression.
Differential Tap Pre-cuts threads for both the leading and trailing ends of the screw in dense cortical bone.

Key Features

  • Headless Compression Technology: Instruments are designed to bury the screw entirely within the bone, preserving joint movement and preventing soft-tissue irritation.

  • Cannulated System: Allows for a minimally invasive “percutaneous” approach, reducing surgical trauma and recovery time.

  • Differential Pitch Accuracy: Specifically calibrated to work with screws that have different thread leads at each end, creating a “pulling” effect to close the fracture gap.

  • Ergonomic Micro-Tools: Scaled down for the fine motor movements required in carpal (hand) and tarsal (foot) reconstructions.

Clinical Indications

  • Scaphoid Fractures: The primary application for stabilizing the small bones of the wrist.

  • Osteochondritis Dissecans (OCD): Fixing small fragments of bone and cartilage within a joint.

  • Small Joint Arthrodesis: Fusion of finger or toe joints.

  • Radial Head Fractures: Stable fixation of intra-articular elbow fragments.
