The Benediction Sign is commonly associated with a median nerve pathology. It is seen when the patient attempts to make a fist but is unable to flex the index and middle fingers at the metacarpophalangeal (MCP) and interphalangeal(IP) joints, causing these fingers to remain extended while the other fingers flex normally. This distinct clinical pres...
Historically, the Benediction Sign has been linked to cultural representations of blessings and greetings, which typically involved an open hand with extended fingers. It was noted in some historical and cultural analyses, such as the research by Futterman , that figures like Peter, the first Pope, might have had an ulnar neuropathy, which influenc...
The median nerve originates from the brachial plexus and primarily innervates the first and second lumbricals of the hand, among other structures. In the case of Benediction Sign, the inability to flex the second and third digits arises from damage to this nerve. However, ulnar nerve pathology affects the fourth and fifth digits, leading to what is...

The presentation involves these fingers remaining extended during an attempt to make a fist. This should not be confused with ulnar nerve symptoms, which affect the outer digits of the hand.
The differential diagnosis should consider other conditions that mimic the posture of Benediction Sign but are due to different underlying causes, such as rheumatoid arthritisor other forms of peripheral neuropathy.
The treatment of Benediction Hand involves the management and treatment of the underlying median nerve pathology. Treatment options may include: 1. Non-steroidal inflammatory drugs (NSAIDs) to control pain and prevent symptoms to get worse. 1. Use of hand or wrist brace to minimise further nerve compression and excessive bending. 2. Hand stretching...
