Which of the following describes the most desirable position in which to immobilize the hand?

E. Wrist is extended, MCP joints are flexed, and IP joints are extended.

DISCUSSION: Plaster splints and dressings should hold the digits in the “intrinsic plus” position. This includes 60 to 80 degrees of flexion at the MCP joints, 10 to 20 degrees of flexion at the proximal interphalangeal (PIP) joints, and 5 to 10 degrees of flexion at the distal interphalangeal (DIP) joints. With the MCP joints in flexion and the PIP joints in extension the collateral ligaments are elongated, thereby decreasing the likelihood of ligament contracture and subsequent joint stiffness. At times, however, the PIP joint is immobilized in greater flexion to correct palmar angulation and to maintain proper rotation of the digit after an unstable fracture.
