距骨骨折後の距骨壊死について

抄録

Ten patients in whom fracture of the talus with or without dislocation was recently treated in our clinic and related hospitals have been followed up (average 2 years and 6 months).
Avascular necrosis of the body of the talus occurred in 5 patients (50%).
They had often associated with the subtalar luxation and/or the fracture of the malleolus, but had no close relation to initial treatment.
Sufficient riduction, stable fixation and non weight bearing are the principle of treatment to prevent avascular necrosis and osteoarthritis of the ankle joint.
If avascular necrosis is recognized, non weight bearing extending a long period of time will be necessary in anticipation to replace necrosis mass by new bone.
