Background

  • Intra-articular fracture

Clinical Features

  • Swelling, decreased ROM, and TTP of MCP joint

Differential Diagnosis

Hand and Finger Fracture Types

Evaluation

Physical

  • Assess for rotational alignment (rotational malalignment is not tolerated)
  • Assess for skin integrity (maintain high index of suspicion for Closed fist infection)[1]

Imaging

  • AP, lateral, oblique
    • Angulation assessed on lateral view
  • Consider "Brewerton view (X-Ray)" if collateral ligament avulsion fracture suspected

Management

General Fracture Management

Specific Management

  • Ulnar Gutter Splint or Short arm cast that extends to the PIP joint
    • In a comparison of the typical 4th and 5th digit flexed at the MCP joint and a short arm, there was no significant benefit to the intrinsic plus position of the fingers[2]
  • Remove restrictive clothing, jewelry, etc.

Disposition

  • Almost always refer because are intraarticular and typically comminuted
  • Dorsal MCP wounds and lacerations should be treated as open and contaminated[1]
  • Non-displaced fracture can be splinted for 2-3 weeks followed by ROM exercises

Indications for Subsequent Out-Patient Orthopedic Surgery

  • Majority are operative, as no degree of articular displacement is acceptable
