Key Attributes
The splint's hospital-grade alloy shell is malleable for optimal fit yet rigid enough be be highly durable.

The anatomical contours are the backbone of the splint's superior fit.

The expanded heel pocket supports deep heal relief.

The splint's straps make donning and doffing for therapy and wound care easy.

The functional ankle position reduces the risk of stiffness and speeds healing.

Sizing
The Seattle Splint comes in four adult sizes and three children's sizes. Use the chart below to choose the proper size keeping the following guidelines in mind:
- Allow for a hand’s width between back of knee and top of splint.
- Toes should not extend over the splint.
- The splint must allow full knee flexion.
Customization
How to Customize the Seattle Splint for your Patient
The Seattle Splint’s malleable alloy shell allows practitioners to form the splint to fit each patient. The sides of the splint, the ankle width, and angle of the splint can be modified without tools.
Our orthoses are professional products designed to be custom fit by knowledgeable practitioners. In addition to the information here, we gladly provide training and support as needed via video conferencing.
Conform to the Calf
While the Seattle Splint is on the patient, cradle the back of the splint in your hands and squeeze the sides together to narrow and form the splint around the calf.
Adjust the Calf Width
Place the back of the Seattle Splint against your chest for support as you spread the splint’s sides to the desired calf width.
Adjust the Ankle Width and Angle
Position the Seattle Splint over the back of a chair and push down above, and then below the weld line to adjust the splint’s ankle width or increase dorsiflexion by up to 5°. Never push directly on the weld line.
Putting on the Seattle Splint
Place foot flat against the foot plate.
Gently, yet firmly, push down at the anterior ankle to slide the foot down into the splint at a neutral position.
Cross the padded ankle strap over the ankle to buckle.
Slide the bar of the slide buckle into the hook buckle.
Pull on the strap to tighten. DO NOT OVERTIGHTEN. A finger should easily slide under the pad.
Cross the second ankle strap over the pad. Buckle. Bring the padded shin strap across the tibia and buckle.
Using the Buckles
To buckle, the slide bar goes onto the hook.
To tighten, pull strap end.
To loosen, pull the strap over the hook to release.
To unhook, turn the slide bar like a key to slip it out of the hook.
Download Patient Instructions
The patient instructions are a printable document for practitioners to use when sending a patient home with a Seattle Splint. This document explains how to put on and remove the splint, how to use the buckles, how to properly take care of the splint, and a section for practitioners to fill out wear schedule and instructions.
Optional Components
Thigh Extension
The Thigh Extension attaches to any adult-sized Seattle Splint, converting it to a Seattle Long Leg. When accurately sized to a splint, the knee is positioned at 0°. Strategically placed movable straps provide counterforce while relieving circumferential pressure. The converted Seattle Splint allows easy access for dressing changes, wound care, arterial monitoring and therapy.
Anterior Shell
The Anterior Shell provides counterforce and support to ensure a neutral position of the ankle in cases of deformity or high tone. The shell distributes pressure to prevent further complications in patients with pitting edema or fragile skin.
