When splinting, what is the recommended MCP position for safe splinting?

The recommended metacarpophalangeal (MCP) position for safe splinting is 70-90 degrees of flexion. This range allows for optimal positioning that facilitates healing while also allowing for some functional movement of the fingers. Maintaining the MCP joints in this position reduces the risk of stiffness and promotes better alignment of the finger structures, which is essential for recovery.

In this position, the flexion reduces the stress on the extensor tendons and allows for effective positioning of the thumb and the remaining fingers. It helps to prevent the complications associated with prolonged immobilization, such as joint contractures and muscle atrophy. Furthermore, this degree of flexion balances the necessary immobilization while allowing for some functional positioning, which can assist with daily activities and rehabilitation efforts post-injury.

Positioning the MCP joints at either extreme, such as in full extension or significant flexion, may lead to complications. For example, full extension can immobilize the joints too tightly, potentially leading to stiffness and reduced range of motion. Meanwhile, significant flexion may not provide the stability needed for healing. Thus, the 70-90 degrees flexion is considered the most effective for safe splinting practices.
