What is Claw Hand?
Claw hand, or claw deformity, is a condition where fingers are curled or bent into a claw-like position. It typically results from nerve damage, impacting the muscles in the hand, causing fingers to bend towards the palm.
Ulnar Nerve Damage Impact
The ulnar nerve controls fine motor movements in the hand. Damage to this nerve can result in claw hand. This nerve runs from the neck down to the hand, making it prone to injury at multiple points along its path.
Less-Known Causes
While trauma is a common cause, claw hand can also result from conditions like leprosy, diabetes, and Charcot-Marie-Tooth disease. These conditions can lead to peripheral neuropathy, causing the characteristic deformity.
Treatment Options
Treatment varies from physical therapy to surgical nerve repair. Splinting and occupational therapy help maintain hand function. Advanced cases may require tendon transfers or nerve grafts to restore mobility and strength.
Surprising Fact
Did you know? Claw hand can also be a congenital condition present at birth. In some cases, genetic factors play a role, leading to muscle imbalance and joint contractures that cause the clawed appearance.Unexpected Trigger
Claw hand can develop simply from long-term use of crutches! The pressure can damage nerves, surprisingly leading to this deformity.
