Crutchfield tongs are skull traction tongs used to apply axial traction to the cervical spine for the management of cervical fractures, dislocations, and subluxations. Designed in the 1930s by William Gayle Crutchfield, an American neurosurgeon at the University of Virginia, they were the first widely-used skull traction device and remain in clinical use as a fallback when modern alternatives (Gardner-Wells tongs, Mayfield headrest) are unavailable.
This guide is written for neurosurgical residents, trauma OR teams, and procurement managers stocking spinal trauma instrumentation. As an ISO 13485-certified manufacturer of CE-marked surgical instruments since 1980, we cover the clinical indications, anatomy, and material requirements for safe Crutchfield tong application.
What Are Crutchfield Tongs?
Crutchfield tongs are a skull traction device — two pointed pins anchored into the outer table of the parietal bone, connected by a U-shaped frame, with a traction rope attached to the apex of the U. The device transmits axial traction force from a weight system through the skull to the cervical spine, reducing fracture displacement and stabilizing the spine while definitive treatment is planned.
The instrument was developed by William Gayle Crutchfield (1900–1972), Professor of Neurosurgery at the University of Virginia. He published his original technique in 1933, and Crutchfield tongs became the standard skull traction device in North American spine surgery for the next several decades. They have largely been replaced by Gardner-Wells tongs and halo devices in modern practice, but remain in clinical inventories for specific indications and resource-limited settings.
Anatomy of the Instrument
A Crutchfield tongs set has four functional parts:
- Two skull pins (points) — sharp threaded pins that anchor into the parietal bone. Most modern Crutchfield variants have 5 mm pin diameter with a flange to prevent over-insertion.
- Adjustable arms — the two arms that hold the pins. Adjustable to accommodate different skull diameters.
- Locking screws — secure each arm to the apex frame at the desired width.
- Traction yoke — the apex of the U-frame where the traction rope attaches.
Surgical-grade Crutchfield tongs are manufactured from AISI 420 stainless steel. Pin tips are precision-ground to a sharp point with a flange that prevents penetration beyond the outer table of the skull.
Clinical Uses
Cervical Spine Trauma — Fracture Reduction
The classic indication. For unstable cervical fractures (e.g., bilateral facet dislocation, burst fracture with displacement), Crutchfield tongs apply axial traction to gradually reduce the displacement. Weight is added incrementally (5 lbs / 2.3 kg per cervical level, up to 50–70 lbs total in selected cases) under fluoroscopic guidance.
Cervical Spine Stabilization Pre-Surgery
While the patient awaits definitive surgical stabilization (anterior cervical discectomy and fusion, posterior fusion), Crutchfield tongs provide stable axial traction.
Resource-Limited Settings
Halo vests and Gardner-Wells tongs are more common in well-resourced centres. Crutchfield tongs remain useful in settings without those alternatives — they are simple, robust, and require no consumable accessories.
Clinical technique for skull traction is learned under specialist neurosurgical supervision. Inappropriate weight, pin placement, or skull penetration causes serious complications. This guide is reference material, not procedural instruction.
Crutchfield vs Gardner-Wells vs Halo: Modern Choice
| Device | Pin design | Application | Modern use |
|---|---|---|---|
| Crutchfield | 2 sharp threaded pins requiring scalp incision | Skull traction, in-bed | Fallback / resource-limited |
| Gardner-Wells | 2 spring-loaded blunt pins, no incision | Skull traction, in-bed | Standard modern skull traction |
| Halo (with vest) | 4 pins through halo ring | Ambulatory stabilization | Standard for non-operative cervical immobilization |
Gardner-Wells tongs largely replaced Crutchfields because they don’t require scalp incision — the spring-loaded pins seat into bone through intact scalp. Halo devices are preferred when ambulatory stabilization is needed.
Material and Manufacturing
Crutchfield tongs are manufactured from AISI 420 martensitic stainless steel. The skull pins specifically must be hardened to 56–58 HRC for sharp point retention through repeated use; the frame and adjustable arms are 45–50 HRC for strength without brittleness.
The pin geometry is critical — too sharp and the pin penetrates the inner table of the skull (catastrophic); too blunt and the pin slips on the outer table during traction. Surgical-grade tongs have a calibrated pin tip with an integrated flange that prevents over-insertion.
Sterilization and Care
Crutchfield tongs see direct bone contact, so reprocessing is rigorous:
Step 1 — Pre-soak in enzymatic cleaner immediately after removal. Blood and tissue fragments collect at the pin tips and threads.
Step 2 — Manual cleaning. Brush every part — pin threads, locking screws, frame. Pay special attention to pin tips.
Step 3 — Ultrasonic. 8–10 minutes at 40 kHz with neutral pH detergent.
Step 4 — Rinse, dry, inspect. Distilled water rinse. Inspect pins for sharpness — dulled or bent pins must be retired or replaced.
Step 5 — Lubricate. Locking screws and arm adjustment threads.
Step 6 — Pack. Single set in sterilization tray. Pins separately wrapped to protect points.
Step 7 — Steam autoclave. 134 °C, 3-minute hold (ISO 17665 / EU MDR 2017/745).
Step 8 — Storage. Sealed sterilization wrap.

Frequently Asked Questions
What are Crutchfield tongs used for?
Crutchfield tongs are used for skull traction in the management of cervical spine fractures, dislocations, and subluxations. They apply axial traction force to gradually reduce fracture displacement and stabilize the cervical spine while the patient awaits definitive surgical treatment. They are also used in resource-limited settings where Gardner-Wells tongs or halo devices are not available.
Why are they called Crutchfield tongs?
The instrument is named after William Gayle Crutchfield (1900–1972), an American neurosurgeon at the University of Virginia who published the original design in 1933. His skull traction technique became the standard in North American spine surgery for several decades before being largely replaced by Gardner-Wells tongs.
What is the difference between Crutchfield and Gardner-Wells tongs?
Crutchfield tongs use sharp threaded pins that require a scalp incision to seat into bone. Gardner-Wells tongs use spring-loaded blunt pins that seat through intact scalp without incision. Gardner-Wells is the modern standard because it’s faster to apply and avoids the scalp wound. Crutchfield tongs remain in use in some centres and resource-limited settings.
How much traction weight is used with Crutchfield tongs?
The standard guidance is approximately 5 pounds (2.3 kg) per cervical vertebral level, applied incrementally under fluoroscopic guidance. Most cervical fractures require 15–35 lbs total. Bilateral facet dislocation reduction may require up to 50–70 lbs in selected cases. The weight is increased gradually with serial radiographs to monitor reduction.
Can Crutchfield tongs be reused?
Yes — they are reusable surgical-grade instruments. After each use, they undergo full reprocessing (enzymatic pre-soak, manual cleaning, ultrasonic, autoclave). Pins must be inspected for sharpness and bending before each application — dulled or bent pins are retired.
How long do Crutchfield tongs last?
The frame of a surgical-grade Crutchfield set lasts indefinitely with correct care. The pins are the wear point — sharpness degrades after 10–20 uses depending on patient anatomy and pull-out force. Most institutions stock replacement pins separately and replace them as needed.
