Understanding Finger Fractures

Introduction to Finger Fractures

The human hand is an intricate structure composed of 27 bones that form the wrist, palm, and fingers. The fingers are particularly vulnerable to injury due to their frequent use in daily activities and the delicate nature of the bones within them. A finger fracture occurs when one of these bones breaks, typically as a result of trauma.

Among all hand fractures, injuries to the metacarpal bones, particularly those connected to the little finger, are the most common, accounting for about one-third of all cases. These fractures can range from simple breaks, where the bone remains in alignment, to more severe cases where the bone is shattered into multiple pieces.

Common Causes of Finger Fractures

Finger fractures are typically the result of significant force applied to the hand, leading to a break in one or more of the delicate bones that make up the fingers. These injuries can occur under various circumstances, often when the hand is exposed to high-impact situations. Below is a more detailed exploration of the common causes of finger fractures:

1. Falls

Mechanism: One of the most frequent causes of finger fractures is a fall, particularly when the individual instinctively extends their arm to break the fall. When the hand makes contact with the ground, the force of the impact is transmitted through the fingers, potentially causing the bones to fracture. The severity of the fracture often depends on the height from which the person falls and the surface they land on.

Common Scenarios:
 

• Slips on Wet or Icy Surfaces: These are particularly common during winter months or in environments where spills are not promptly cleaned up. A sudden loss of balance can cause a person to fall, leading to a reflexive extension of the hand to prevent further injury, resulting in finger fractures.

​

• Trips Over Obstacles: Uneven pavements, cluttered walkways, or unseen objects on the floor can lead to tripping, which often ends with the person landing on their hands.

​

• Falling from Heights: Falls from ladders, stairs, or elevated platforms can generate enough force upon impact to cause fractures in the fingers, especially if the fall is from a significant height.

​

2. Motor Vehicle Accidents

Mechanism: The violent forces involved in motor vehicle accidents can directly impact the hands, particularly if they are on the steering wheel, dashboard, or are otherwise engaged in bracing for impact. The energy from the collision can cause the bones in the fingers to fracture, sometimes alongside other injuries.

Common Scenarios:
 

• Car Crashes: During a collision, the driver or passenger may instinctively grip the steering wheel tightly or brace their hands against the dashboard, exposing the fingers to the force of the crash, which can lead to fractures.

​

• Motorcycle and Bicycle Accidents: In accidents involving motorcycles or bicycles, the rider may be thrown off, landing on their hands. The direct impact with the ground or another vehicle can easily fracture the fingers.

​

• Airbag Deployment: While airbags are designed to save lives, the rapid deployment can cause significant force against the hands if they are positioned near the steering wheel at the moment of inflation, potentially leading to fractures.

​

3. Sports Activities

Mechanism: Many sports involve high speeds, physical contact, or sudden, unexpected impacts, all of which can result in finger fractures. Athletes are particularly at risk during activities where falls, collisions, or forceful impacts with sports equipment are common.

Common Scenarios:
 

• Contact Sports: Sports such as football, rugby, and hockey involve frequent physical collisions with other players, the ground, or equipment. These impacts can easily result in fractures, particularly when the fingers are directly involved in catching, blocking, or tackling.

​

• High-Impact Activities: Sports like snowboarding, skateboarding, and gymnastics involve high speeds and the potential for falls from considerable heights or during complex manoeuvres. When athletes fall, they often extend their hands to break the fall, leading to finger fractures.

​

• Ball Sports: In sports like basketball, volleyball, or cricket, the fingers are frequently exposed to impact from fast-moving balls, which can jam or hyperextend the fingers, resulting in fractures.

​

• Racquet Sports: Tennis, squash, and similar sports involve rapid wrist and finger movements to control the racquet. A sudden miss-hit or overextension can lead to fractures, particularly in the small bones of the fingers.

​

4. Physical Altercations

Mechanism: Engaging in physical altercations, whether intentional (such as in a fight) or accidental (such as punching a hard object in frustration), can lead to fractures, particularly in the bones of the little finger. The force of impact when the hand strikes a hard surface can easily cause the bones to break.

Common Scenarios:
 

• Fist Fights: During a physical altercation, punching another person or being punched can result in fractures, especially if the punch lands awkwardly or with excessive force. The bones of the hand are not designed to absorb the impact of punching, especially when the hand is not properly aligned.

​

• Punching Hard Objects: Out of frustration or anger, individuals may punch walls, doors, or other hard surfaces. The bones in the fingers, particularly the metacarpals that connect the fingers to the hand, are vulnerable to breaking upon impact, commonly resulting in what is known as a "boxer’s fracture."

​

• Accidental Impact: In moments of inattention, people might accidentally slam their hands against hard objects, such as a car door or a piece of furniture, leading to a fracture.
