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
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;
- Treatment:
- 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;
