The SplintER series is back with its fourth installment! In this series, we review splinting fundamentals, introduce advanced concepts, and highlight ways to implement these into your next shift. In this post, we summarize some of the most commonly deployed splints in the ED. Peer-reviewed by sports medicine experts (Dr. Kori Hudson and Dr. Anna Waterbrook), these injury-splint summary tables provide information on the origin, insertion, and positioning for each splint, along with the recommended number of layers of plaster.

Learning Objectives

  1. Review splint techniques associated with injuries commonly managed in the ED.
  2. Learn some basic tips to help with successful placement of these splints.

Understanding proper splinting technique is a critical skill for all emergency physicians. Though many facilities have nurses and patient care technicians who may assist with splint application, the ultimate responsibility for proper splint application lies with the physician.

Critical Basics:

  1. Protect the skin: Head from splint activation can cause burns. Wrinkles in layers can cause friction, blisters, or infection.
  2. Ensure patients understand splint care: showering, weight bearing, unwrapping and re-wrapping if the splint feels too tight. Proper follow-up is critical.

Tricks of the Trade:

  1. Makeshift Cuff and Collar: Use a disposable wrist restraint to create this splint.
  2. How to avoid the mess of plaster: Before activation, layer plaster and place in a sleeve (stockinette). Place the sleeve into lukewarm water, and remove excess water by sliding the sleeve between your index and long finger. Mold the sleeve to the affected body part.
  3. Remember the equinus position: Utilize this for Dancer’s fractures and Achilles ruptures.

The most important advice: Practice splinting! Make your own splints and check the ones that nurses and  technicians make for your patients. If it isn’t right, try making it again. In some cases, a bad splint may be worse than no splint at all!
