Study Notes
Median Nerve Palsy - "Hand of Benediction"
- "Hand of Benediction" is often misused. It precisely describes a proximal median neuropathy, but can also be used to describe ulnar clawing.
Traditional Description
- Typically, the "hand of benediction" presentation features hyperextension of the metacarpophalangeal (MCP) joints of the second and third digits.
- This hyperextension results from the unopposed action of the extensor digitorum muscles.
- Loss of function in the two lateral lumbricals, which normally flex the MCP joints, contributes to the hyperextension.
- The interphalangeal (IP) joints of the second and third digits are inflexible due to the loss of function of the lateral half of the flexor digitorum profundus.
Recent Studies
- Recent studies have challenged aspects of this traditional description.
