Phalangeal Base Fracture Etiology / Epidemiology / Natural History

Phalangeal Base Fracture Anatomy

Phalangeal Base Fracture Clinical Evaluation

  • evaluate finger cascade with flexion. Any overlaps of injured digits indicates need for reduction +/- fixation.

Phalangeal Base Fracture Xray

  • P/A and lateral views of affected finger
  • 30-45 degree suppinated or pronated views

Phalangeal Base Fracture Classification / Treatment

  • Undisplaced, displaced unicondylar fx involving <25% of articular surface without joint subluxation/deformity: buddy taping
  • Displaced unicondylar: Closed reduction under c-arm guidance, generally requires pointed reduction forceps. Cannulated reduction forceps facilitates K-wire placement. ORIF if closed reduction fails (Tan V, JOT 2005;19:518)
  • Displaced Bicondylar: almost always unstable. CRPP. Generally joint is reduced and rixed with transverse k-wires placed parallel to joint surface. Metaphysis is then reduced and secured to the diaphysis with two K-wires inserted from the tip of each condyle proximally into the medullary canal distally. Also consider ORIF if closed recuction fails (Tan V, JOT 2005;19:518)
  • Open fracture: consider mini-external fixation. (Freeland AE, CORR, 1987;214:93)

Phalangeal Base Fracture CRPP Technique

  • Belsky MR, J Hand Surg 1984;9Am:725
  • 0.045 (1.1mm) K-wires generally used. Consider 0.062in(1.6mm) for larger bones(metacarpal); 0.035in(0.9mm) for smaller bones (pediatric fx).
  • Closed reduction under c-arm guidance.
  • one or more intramedullary or two crossed K-wires.
  • K-wires must not cross at the fracture site.
  • K-wires are left in until fracture callus in visible on xray. Usually 3-4 weeks

Phalangeal Base Fracture ORIF Technique

  • Mid-axial incision centered over fx

Phalangeal Base Fracture Associated Injuries

  • Adjacent phalanx or metacarpal fractures
  • Carpal fractures
  • fight bite (high risk of injection)
  • Phalangeal Shaft Fracture
  • Phalangeal Neck Fracture
  • Distal Phalanx Fracture

Phalangeal Base Fracture Complications

  • Flexion Contracture: see Hogan CJ, JAAOS 2006;14:524.
  • Loss of reduction
  • Delayed union
  • Malunion
  • Tendon adhesion / stiffness
  • Cold intolerance
  • Numbness
  • Abnormal nail growth
  • Nerve or vascular injury

Phalangeal Base Fracture Follow-up

  • Weekly follow-up until fracture callus is seen on xrays is indicated to ensure reduction is maintained
  • Advance to passive ROM / Buddy taping as soon as fracture allows.
