Overview

Finger fractures account for approximately 10% of all fractures and are the most common fractures of the hand. Each finger contains three bones called phalanges (except the thumb, which has two), and the hand bones that connect to the fingers are called metacarpals. Any of these bones can fracture from direct trauma, twisting injuries, or crushing forces.

The complexity of finger fractures varies widely, from simple, stable fractures that heal well with conservative treatment to complex injuries requiring surgical intervention. The location and pattern of the fracture, along with associated soft tissue damage, determines the treatment approach and prognosis. Proper diagnosis and treatment are crucial because even seemingly minor finger fractures can lead to permanent deformity, stiffness, or loss of function if inadequately managed.

The fingers play a vital role in hand function, enabling precise movements necessary for daily activities, work, and recreation. A fracture can significantly impact quality of life, affecting everything from writing and typing to playing sports and musical instruments. Early recognition, appropriate treatment, and proper rehabilitation are essential for optimal recovery and return to normal function.

Symptoms

The symptoms of a finger fracture can vary depending on the location, severity, and type of fracture. Recognition of these symptoms is important for seeking timely medical attention.

Primary Symptoms

Common Signs and Symptoms

  • Deformity - Visible angulation, rotation, or shortening of the finger
  • Bruising - Discoloration appearing within hours to days
  • Tenderness - Point tenderness directly over the fracture site
  • Inability to move - Difficulty or inability to bend or straighten the finger
  • Numbness or tingling - May indicate nerve involvement
  • Crepitus - Grinding sensation with movement (should not be tested)

Severity Indicators

  • Open fracture - Bone visible through skin wound
  • Complete loss of function - Unable to move finger at all
  • Severe deformity - Obvious malalignment
  • Vascular compromise - Pale, cold fingertip
  • Joint involvement - Fracture extending into joint space

Causes

Finger fractures result from various mechanisms of injury, each potentially causing different fracture patterns and associated injuries.

Direct Trauma

  • Crush injuries - Heavy objects falling on fingers, car doors, hammers
  • Direct blows - Sports impacts, fights, accidents

Diagnosis

Accurate diagnosis of finger fractures involves clinical examination and imaging studies to determine the type, location, and severity of the fracture.

Clinical Examination

  • History taking - Mechanism of injury, timing, previous injuries
  • Visual inspection - Deformity, swelling, wounds, bruising
  • Palpation - Point tenderness, crepitus, stability
  • Range of motion - Active and passive movement assessment
  • Neurovascular exam - Sensation, circulation, capillary refill
  • Tendon function - Flexor and extensor tendon integrity

Imaging Studies

X-rays:

  • Standard views - AP, lateral, and oblique projections
  • Entire hand films - To rule out associated injuries
  • Comparison views - Opposite hand for pediatric cases
  • Special views - For specific fracture patterns

Advanced Imaging:

  • CT scan - Complex fractures, intra-articular injuries
  • MRI - Soft tissue injuries, ligament damage
  • Ultrasound - Dynamic assessment, tendon evaluation

Fracture Classification

  • Location - Proximal, middle, or distal phalanx; metacarpal
  • Pattern - Transverse, oblique, spiral, comminuted
  • Displacement - Non-displaced, displaced, angulated
  • Joint involvement - Extra-articular vs intra-articular
  • Stability - Stable vs unstable patterns
  • Open vs closed - Skin integrity

Common Fracture Types

  • Mallet finger - Distal phalanx with extensor tendon injury
  • Bennett's fracture - Thumb metacarpal base
  • Boxer's fracture - Fifth metacarpal neck
  • Volar plate avulsion - PIP joint injury
  • Seymour fracture - Pediatric distal phalanx with nail bed injury

Treatment Options

Treatment of finger fractures depends on the fracture type, location, stability, and patient factors. The goal is to restore anatomy, maintain function, and prevent complications.

Conservative Treatment

Splinting and Immobilization:

  • Buddy taping - Simple, stable fractures taped to adjacent finger
  • Aluminum splints - Moldable support for specific positions
  • Stack splints - For mallet finger injuries
  • Ulnar gutter splints - Fourth and fifth finger fractures
  • Radial gutter splints - Second and third finger fractures
  • Duration - Typically 3-6 weeks depending on fracture

Closed Reduction:

  • Digital block - Local anesthesia for pain control
