Contributor(s):

Synonym(s): Distal ulnar plate closure


Introduction

  • Higher incidence than distal radial growth plate closure Radius: distal growth plate closure.
  • Cause: direct trauma, known or unknown.
  • Signs: bowing of radius, deviation of carpus (carpal valgus), external rotation at the carpus, subluxation of elbow joint, osteoarthritis.
  • Treatment: surgical intervention to restore elbow joint to normal congruity and lengthen/straighten entire antebrachium.
  • Prognosis: fair - degenerative joint disease (DJD) a common sequela.

Pathogenesis

Etiology

  • Trauma.

Pathophysiology

  • Elbow changes caused either by relative overgrowth of radius in proximal and lateral direction, or displacement of proximal ulna distally.
  • Distal humerus is squeezed between radial head and anconeal process - subluxation of joint and osteoarthritis.
