How do Static splint, Dynamic splint compare side by side?
The table below compares Static splint, Dynamic splint across 10 procurement-relevant dimensions, from does the splinted part move? through source.
Side-by-side comparison
| Dimension | Static splint | Dynamic splint |
|---|---|---|
| Does the splinted part move? | No. Cleveland Clinic: the splint holds your body part completely still. | Yes, within limits. Cleveland Clinic: you can move your splinted body part, but only a specific amount your provider sets. |
| How it is built | Performance Health (a vendor article) says a static splint has no moving parts. | Performance Health says a dynamic splint has a static base onto which levers, springs or pulleys can be attached. |
| What it is described as doing | Performance Health: it can be used for support, protection or correction. | Cleveland Clinic (finger splints): dynamic splints let you move your finger with support, and can be helpful if your provider recommends stretches or movements as part of recovery. |
| Who sets or changes it | A plain static splint stays as made. The adjustable relative is the static progressive splint, which Cleveland Clinic says does not let you move but is adjustable; your provider may adjust its position over time to stretch your body. | Cleveland Clinic: your provider may adjust how far you can move in your splint. |
| Static progressive vs dynamic | Static progressive: no movement, adjustable position. Performance Health says it applies a low-load prolonged stretch at the end of the available movement. | Dynamic: movement is allowed, up to an amount the provider sets. This is the core difference from a static progressive splint. |
| Serial static splints | Cleveland Clinic: serial static splints hold the body part at the furthest point of its range of motion, so tissue around an injury stays stretched and flexible while it heals. Performance Health describes them as positioning soft tissues toward the end of available range of motion. | Not a dynamic design: a serial static splint still holds the part in one position rather than allowing set movement. |
| Finger splints | Cleveland Clinic lists gutter, ulnar gutter, buddy (two-finger), stack and thumb spica splints separately from the dynamic type. A gutter splint is a rigid U-shaped support. | Cleveland Clinic: a frame that might have a spring or hinged joint surrounds the finger on the palmar side and sides; it lets you move your finger with support, much as you can move your knee in a knee brace. |
| How catalogs and HCPCS descriptors label them | In CASRAI's wrist brace HCPCS guide, L3906 is described as a static rigid or semi-rigid wrist-hand orthosis, and CGS Administrators describes L3807 as a static prefabricated custom-fitted wrist-hand-finger orthosis. | In the same guide, L3806 (wrist-hand-finger orthosis, nontorsion joint(s), custom fabricated, includes fitting and adjustment) carries the descriptor (dynamic). |
| When each applies | Applies when the treatment plan calls for the part to be held still. Static progressive and serial static variants add a provider-managed stretch. | Applies when the treatment plan calls for a provider-set amount of movement. Your provider chooses the type; this page does not recommend one for any injury. |

Common questions
Common questions about Static splint vs Dynamic splint
What is the difference between a static and a dynamic splint?
+
A static splint holds the body part completely still. A dynamic splint lets you move the splinted part, but only the amount your provider sets (Cleveland Clinic, Splint, read 2026-11-01).
What is the difference between a static progressive splint and a dynamic splint?
+
A static progressive splint does not let you move but is adjustable, so a provider can change its position over time to stretch the body part. A dynamic splint allows movement within a provider-set range (Cleveland Clinic, read 2026-11-01).
What is a dynamic finger splint?
+
Cleveland Clinic describes it as a frame, which might have a spring or hinged joint, around the palmar side and sides of the finger. It lets you move the finger with support.
What is a serial static splint?
+
A splint that holds the body part at the furthest point of its range of motion; providers use it so tissue around an injury stays stretched and flexible while it heals (Cleveland Clinic, read 2026-11-01).
How do I know which type I need?
+
Your healthcare provider decides which splint type fits your injury and sets or adjusts any allowed movement. This page is general information, not medical advice.
