Broken Nail Extraction Instrument Overview

The Broken Nail Extraction Instrument Set is a complete revision-surgery toolkit for removing failed internal fixation hardware. It addresses the three most common removal scenarios: broken or stripped screw heads, broken intramedullary nails, and screws with damaged drive recesses. The 50-piece set covers screwdriver drives from 0.5mm Phillips through SW5.5 hex and T2.3–T5.3 star, extraction screws with 0.5/1.0mm pitch, hollow reamers from Φ2.7 to Φ10, threaded extraction bolts Φ3.5–Φ6.5, and high-speed drill bits for pilot channel preparation.

Every instrument is machined from high-strength 316L stainless steel to withstand the torsional loads encountered when freeing corroded or cold-welded hardware.

Clinical Indications

  • Broken Screw Head Removal: Extraction screws hexagonal 2.5mm with 0.5mm pitch and 1.0mm pitch (Ref 308-1821/308-1822) engage broken screw shafts for reverse-thread extraction.
  • Stripped Drive Recess Recovery: Hexagonal screwdrivers SW1.5–SW5.5 and star screwdrivers T2.3–T5.3 (Ref 308-1805/308-1813, 308-1814/308-1820) extract screws with intact drive recesses.
  • Broken Intramedullary Nail Extraction: Hollow reamers Φ2.7–Φ10 in sawtooth configuration (Ref 308-1825/308-1831) core out bone around broken nail fragments; extraction bolts Φ3.5–Φ6.5 (Ref 308-1832/308-1835) engage the nail lumen for removal.
  • Failed Internal Fixation Revision: Screw extractors Φ3.5/Φ4.5 (Ref 308-1845/308-1849) and pliers for screw removal (Ref 308-1846) handle residual fragments after primary extraction.
  • Spinal Hardware Removal: The spinal monoaxial pedicle screwdriver (Ref 308-1843) supports removal of broken pedicle screws and spinal fixation hardware.

Key Features & Advantages

  • Full Drive Coverage: 20 screwdrivers — Phillips, square, hexagonal (SW1.5–SW5.5), and star (T2.3–T5.3) — match virtually all modern screw drive types.
  • Progressive Extraction System: Extraction screws (0.5/1.0mm pitch) → hollow reamers (sawtooth) → extraction bolts (threaded) provide a stepwise escalation for stubborn hardware.
  • High-Speed Drill Bits: Φ4×36×80mm, Φ6×36×80mm, and Φ8×36×70mm (Ref 308-1838/308-1840) create pilot channels around embedded hardware under power.
  • Specialized Removal Tools: Sharp hook, round gouge 8mm, tip screwdriver, and pliers for screw removal handle fragment retrieval and soft-tissue clearance.
  • Quick-Coupling Handles: T-shaped and straight quick-coupling handles (Ref 308-1847/308-1848) provide maximum torque transmission for extraction maneuvers.

Frequently Asked Questions

The set handles: (1) screws with intact drive recesses — via Phillips (0.5mm), square (1.1–1.5mm), hexagonal (SW1.5–SW5.5), and star (T2.3–T5.3) screwdrivers; (2) broken screw shafts — via extraction screws with 0.5mm and 1.0mm pitch (Ref 308-1821/308-1822); (3) broken intramedullary nails — via hollow reamers Φ2.7–Φ10 (sawtooth) and extraction bolts Φ3.5–Φ6.5 (threaded); and (4) residual fragments — via screw extractors Φ3.5/Φ4.5 and pliers for screw removal.

The hollow reamer (e.g., Φ6.5 sawtooth, Ref 308-1829) is advanced over the nail to core out surrounding bone; then the matching extraction bolt (Φ6.5 threaded, Ref 308-1835) is screwed into the nail lumen under the T-shaped quick-coupling handle (Ref 308-1847) for controlled retrograde removal.

Yes. Three high-speed drill bits — Φ4×36×80mm, Φ6×36×80mm, and Φ8×36×70mm (Ref 308-1838/308-1840) — create pilot channels around embedded screws or nail fragments when used with a power driver, reducing manual effort in dense cortical bone.

Yes. All instruments are machined from high-strength surgical-grade 316L stainless steel to withstand the torsional loads of extraction procedures and repeated high-temperature, high-pressure steam sterilization. The instrument box (Ref 308-1850) is an anodized aluminum tray with dedicated slots.

It is compatible with femoral, tibial, and humeral intramedullary nail systems (nail lumen diameters Φ2.7–Φ10), plus pedicle screw systems via the spinal monoaxial pedicle screwdriver (Ref 308-1843). It serves as the essential companion set for any hardware removal or revision surgery.
