An OTR® is treating a client with a boutonniere deformity using conservative splinting. Which statement can the OTR use to educate the client about the proper use of the circumferential proximal interphalangeal (PIP) joint orthosis?

A. Wear the orthosis only at night to maintain the PIP joint in extension when at rest.

B. Remove the orthosis every hour for passive motion exercises.

C. Wear the orthosis continuously for up to 6 weeks.

D. Wear the orthosis during the day, but remove it at night.

The recommended use for a boutonniere deformity is to continuously wear the circumferential proximal interphalangeal (PIP) joint orthosis, including while sleeping, for up to 6 weeks. This approach provides a thorough support structure for the PIP joint, similar to an arm brace supporting a bone structure, for effective healing.

Explanation:

In treating a client with a boutonniere deformity, an Occupational Therapist Registered (OTR) might utilize a circumferential proximal interphalangeal (PIP) joint orthosis as part of an appropriate physical therapy plan.

The OTR can educate the client that the recommended use of this orthosis is to wear it continuously, even during sleep, for up to 6 weeks. This approach (Option C) provides a consistent and thorough support structure for the PIP joint to heal correctly.

The client might compare it to wearing an arm brace. Much like how a brace supports and reinforces the underlying bone structure it is intended to help (Figure 6.4 Arm Brace), the PIP joint orthosis will be providing support to aid in healing the boutonniere deformity. Continuous use allows for effective control of the joint and promotes proper alignment and healing.
