III. Epidemiology

  1. Phalanx Fractures account for 10% of all Fractures and 1-2% of all emergency department visits
  2. Distal Phalanx Fractures are most common
  3. Most commonly caused by work injury or sports injury

IV. Exam

  1. See Hand Exam (includes Hand Neurovascular Exam)
  2. Injury exam mantra: "joint above, joint below, circulation, motor function and sensation, skin and compartments"
  3. Evaluate for flexor and extensor tendon integrity at MCP, PIP and DIP joints
  4. Evaluate for rotational alignment (see below)
  5. Evaluate for open Fracture

V. XRay

  1. Hand or finger xray
    1. Anteroposterior, lateral and oblique views
    2. Rotational abnormalities may appear on lateral xray as variation in phalanx shaft widths

VI. Management: General Principles of Hand Fracture Management

  1. Nerve Block for any manipulation required at time of Splinting
    1. See Digital Nerve Block
    2. See Hand and Wrist Regional Anesthesia
  2. Correct angular malalignment and rotation
    1. Fracture reduction for all unstable, oblique, angulated or displaced Fractures
      1. Obtain post-reduction xrays after reduction and Splinting
    2. Axes of all flexed fingers should point toward Scaphoid Bone or radial styloid (thenar eminence)
      1. OrthoHandPositionFistToScaphoid.jpg
  3. Splinting
    1. Splint in position of moderate flexion
      1. Avoid Splinting fingers in extension (esp MCP)
    2. Avoid over-immobilization (leads to Joint Stiffness and longer recovery)
      1. Stable, non-displaced Phalanx Fractures may be buddy taped with early protected ROM
    3. Gutter splint (Ulnar Gutter Splint or Radial Gutter Splint)
      1. Splint in intrinsic position (30 degrees wrist extension, 90 degrees MCP flexion, IPs in extension)
  4. Evaluate peri-articular Fractures for avulsed tendon
    1. Avulsed fragments are often attached to a tendon or ligament
  5. Outpatient follow-up within 5-7 days
    1. Reevaluate for angulation, rotation or translation

VII. Management: Open Reduction and Internal Fixation (ORIF)

  1. Indications
    1. Malrotation >10 degrees
    2. Unstable displaced intra-articular Fractures
      1. if >25-30% of joint surface involved
  2. Advantages
    1. Avoid excessive manipulation
    2. Avoids prolonged Splinting
