Question 1

Following extensor tendon repair in zone VI, the standard early mobilization protocol positions the wrist at:

Accepted Answer

30–40° extension

Answer

After zone VI extensor repair, the wrist is positioned in 30–40° extension to reduce tension on the repair while early controlled motion is initiated.

Question 2

The purpose of serial static casting or splinting in PIP flexion contracture is to:

Accepted Answer

Achieve incremental gains in extension through tissue creep

Answer

Serial static splinting applies a sustained low-load stretch that promotes plastic deformation (creep) of contracted soft tissue, progressively increasing PIP extension.

Question 3

For carpal tunnel syndrome, a neutral wrist splint worn at night is recommended because:

Accepted Answer

Wrist flexion during sleep increases carpal tunnel pressure

Answer

During sleep, unconscious wrist flexion dramatically increases carpal tunnel pressure and median nerve compression; a neutral splint prevents this positional aggravation.

Question 4

A dorsal blocking orthosis following flexor tendon repair is set with the wrist at approximately:

Accepted Answer

20–30° flexion

Answer

Standard dorsal blocking orthosis post-flexor tendon repair positions the wrist in 20–30° flexion and MCPs in 40–60° flexion to protect the repair while allowing controlled motion.

Question 5

When applying a circumferential orthosis, the therapist should ensure that the orthosis does not compress the:

Accepted Answer

Superficial sensory nerves and bony prominences

Answer

Circumferential orthoses must be relieved over bony prominences and superficial nerves to prevent pressure ulcers and nerve compression injuries.
