Midtarsal Fracture

(see also: Midfoot/Forefoot Fractures; Navicular Frx; Cuboid Frx; Longitudinal Stress Injuries of Midtarsal Joint)

Medial Stress Injury

  • type of sprain of the midtarsal joint;
  • caused by inversion of the foot, inaddition, fracture subluxation of joint may be found;

Lateral Stress Injury

  • this injury is frequently misdiagnosed as an ankle sprain;
  • characteristic feature of these injuries is crushing of cuboid or anterior calcaneus as the forefoot is driven laterally;
  • avulsion fractures of navicular tuberosity are seen frequently, & navicular may subluxate laterally on the talar head;
  • Cuboid Frx is sometimes found with this injury:
    • cuboid is crushed between calcaneus and 4th & 5th metatarsals;
  • treatment includes initial non wt bearing cast for 6-8 weeks;


  • often avulsion of navicular tuberosity is felt to be an isolated injury, and attention is not given to entire mid tarsal joint complex;
  • non displaced fractures may be treated by short leg plaster immobilization  until healed - usually 6 weeks;
  • is satisfactory reduction is not possible, try open reduction & K wire fixation or screw fixation;
  • when injury to this articular complex occurs in the diabetic patient w/ peripheral neuropathy, aaggressive treatment is indicated to avoid late collapse and Charcot arthropathy
