Finger Fractures

Finger fractures refer to breaks in one or more of the bones within the fingers, known medically as phalanges. These injuries can vary in severity from minor cracks to complete breaks that affect the bone’s alignment. Finger fractures are common injuries that can occur in a variety of settings, including sports, work-related activities, and everyday accidents.

Finger fractures are caused by various factors, ranging from accidental trauma to repetitive stress. Common causes of finger fractures include:

• Accidental Trauma
  The most frequent cause of finger fractures. This can occur from a direct blow during sports, a fall, or accidentally striking a hard object.
• Sports Injuries
  Impacts or falls in contact sports, ball games, and sports involving physical contact or the use of equipment can cause finger fractures.
• Work-Related Accidents
  Occupations involving manual labour or machinery use pose a higher risk for finger fractures due to potential impacts or entrapment.
• Falls
  Falling onto an outstretched hand can cause fractures in the fingers, especially if the fingers are positioned awkwardly upon impact.
• Crushing Injuries
  Fingers may be fractured if caught between two hard objects or if subjected to a heavy weight or force.
• Repetitive Motion
  Overuse and repetitive motions can lead to small cracks in the bone, known as stress fractures, in the fingers. This is particularly common in athletes or people performing repetitive tasks for extended periods.

The symptoms of a finger fracture can vary depending on the severity and type of fracture. Common symptoms of finger fractures include:

• Pain
  Intense pain at the site of the fracture, which may worsen when moving the finger or applying pressure.
• Swelling
  The area around the fracture often becomes swollen and tender to touch soon after the injury.
• Bruising
  Discoloration and bruising may appear around the injured area due to underlying bleeding and tissue damage.
• Deformity
  A visible deformity in the finger, such as an abnormal bend or twist, can indicate a severe fracture or dislocation.
• Reduced Mobility
  Difficulty in moving the finger, accompanied by stiffness or inability to bend or straighten the finger fully.
• Numbness or Tingling
  A fracture can affect nerves, leading to a sensation of numbness or tingling in the finger or even in the hand.
• Crepitus
  A sensation or sound of grating, popping, or crackling when moving the finger may be experienced due to the fractured bone ends rubbing together.

Diagnosing a finger fracture involves a combination of clinical evaluation and imaging studies to accurately identify the type and extent of the fracture. The diagnostic process typically includes the following steps:

• Medical History And Physical Examination
  A detailed medical history is initially taken to understand the circumstances leading to the injury. A physical examination is conducted to assess pain, swelling, deformity, and the range of motion in the finger.
• X-Rays
  The most common and crucial imaging test for diagnosing finger fractures. X-rays can clearly show the location, type, and extent of the fracture. Multiple views may be taken to get a comprehensive understanding of the injury.
• Computed Tomography (CT) Scan
  A CT scan may be performed in cases where more detail is needed or if the fracture involves complex finger structures. This imaging test provides a more detailed view of the bone and surrounding tissues.
• Magnetic Resonance Imaging (MRI)
  Although not commonly used for diagnosing simple fractures, MRI can help identify associated injuries to ligaments, tendons, or the soft tissues surrounding the fracture.
• Bone Scan
  On rare occasions, when a stress fracture is suspected but not visible on X-rays, a bone scan may be conducted. This involves injecting a small amount of radioactive material into the bloodstream, which accumulates in areas of bone growth and highlights stress fractures.

Surgical intervention may be required for finger fractures that are displaced, involve the joint, or have multiple fragments that cannot be adequately aligned through non-surgical means. Surgical options for treating finger fractures include:

• Open Reduction and Internal Fixation (ORIF)
  This procedure involves an incision directly accessing the fracture site. The bone fragments are then realigned (reduction) and stabilised using pins, screws, plates, or wires (internal fixation). When the fracture affects the hand’s metacarpal bones rather than the finger bones alone, treatment may involve metacarpal fracture fixation to restore alignment and hand function.
• Closed Reduction and Percutaneous Pinning
  In some cases, the bone fragments can be realigned without making a large incision, through a process called closed reduction. Once aligned, pins are inserted through the skin to hold the bone fragments in place (percutaneous pinning).
• External Fixation
  An external fixator may be used for complex fractures. This involves placing screws or pins into the bone on either side of the fracture, which are then connected to a stabilising frame outside the skin. This method allows for precise adjustment of bone alignment during the healing process.
• Bone Grafting
  A bone graft may be necessary if there is significant bone loss or if the fracture fails to heal (nonunion). Bone tissue, either from the patient’s body (autograft) or a donor (allograft), promotes bone growth and healing.
• Joint Replacement
  In severe cases where the fracture involves extensive damage to a joint, artificial joint replacement (arthroplasty) may be considered to restore function.
