Henning Plaster Spreader

A Henning Plaster Spreader is a specialized orthopedic surgical instrument that primarily assists in procedures involving plaster casts and orthopedic immobilization. Below is a detailed breakdown of its design, purpose, and usage.

Design & Features

• Material: High-quality stainless steel ensures durability, resistance to corrosion, and easy sterilization.
• Structure:
  • The instrument has two robust arms connected by a hinge mechanism.
  • Broad, curved jaws distribute force evenly when spreading plaster.
  • Some models feature serrated inner surfaces for improved grip on hardened plaster.
• Handle:
  • An ergonomic handle design includes ridges or finger loops for a secure grip.
  • Some versions incorporate a ratchet mechanism to maintain the spread without continuous hand pressure.

Purpose & Applications

• Spreads and separates plaster casts during removal or adjustment.
• Expands a split cast to accommodate swelling or further modifications.
• Plays a crucial role in orthopedic and trauma surgery for safe and efficient cast removal.
• Supports veterinary medicine in similar applications for animals requiring plaster immobilization.

Usage & Handling

1. The orthopedic surgeon or technician inserts the jaws of the spreader into the split section of the plaster cast.
2. Applying gradual pressure to the handles widens the split, creating enough space to safely remove or modify the cast.
3. If needed, the ratchet mechanism locks the instrument in place to maintain the spread.
4. Once sufficiently widened, the tool is removed, allowing for additional adjustments like cutting or trimming.
