Which option best describes selecting a splint when time is limited for a PIP extension deficiency after injury?

• A. Prefabricated dynamic PIP extension assist splint
• B. Customized dynamic PIP extension splint
• C. Paraffin therapy followed by joint mobilization
• D. Flexion blocking exercises

Answer: (A)

When time is of the essence, using a ready-made dynamic PIP extension assist splint is the most efficient way to address a PIP extension deficiency after injury. This type of splint provides an immediate extension force to the proximal interphalangeal joint, helping to restore extension while allowing controlled motion at the joint. Because it’s prefabricated, it can be applied right away without waiting for customization, making it cost-effective and easily adjustable to different finger sizes. This supports early mobilization and helps prevent contractures from developing during the healing process.

A customized dynamic PIP extension splint would offer a tailored fit and precise force but requires measurements, fabrication time, and fitting, which isn’t ideal when speed is needed. Parafin therapy with joint mobilization is a therapeutic modality, and flexion-blocking exercises are therapy techniques rather than a splint solution; neither provides the immediate, sustained extension force a prefabricated dynamic splint delivers.
