Injury to the Hand
Physical damage to the hand, fingers, or wrist caused by trauma, accidents, or overuse
Quick Facts
- Type: Traumatic Injury
- ICD-10: S60-S69
- Common in: All age groups
- Recovery: Variable
Overview
Hand injuries are among the most common types of trauma encountered in emergency departments and primary care settings. The hand is a complex structure consisting of 27 bones, numerous joints, tendons, ligaments, muscles, nerves, and blood vessels, all working together to provide intricate movement and sensation. This complexity makes the hand both remarkably capable and vulnerable to various types of injuries.
Hand injuries can range from minor cuts and bruises to severe trauma involving fractures, dislocations, tendon ruptures, and nerve damage. The impact of a hand injury extends beyond the immediate physical damage, as our hands are essential for daily activities, work, and self-care. Even seemingly minor injuries can significantly affect quality of life and functional independence.
The types of hand injuries vary widely and can include fractures of the finger bones (phalanges) or hand bones (metacarpals), sprains and strains of ligaments and tendons, cuts and lacerations that may damage underlying structures, burns, crush injuries, and repetitive stress injuries. Some injuries may involve only soft tissues, while others may affect bones, joints, or vital structures like nerves and blood vessels.
Prompt and appropriate treatment of hand injuries is crucial for optimal healing and restoration of function. The goals of treatment include pain relief, prevention of infection, restoration of anatomy, and preservation or restoration of hand function. Early intervention can often prevent complications and improve long-term outcomes. Understanding the signs and symptoms of serious hand injuries helps ensure timely medical attention when needed.
