Ankle diastasis without fracture.

摘要: Ankle diastasis without associated fracture occurs in a latent form which the is detected only by stress radiographs, and frank with visible on routine, unstressed radiographs. Whereas ankle requires no reduction can be treated cast immobilization, anatomical of mortise. The method depends upon particular type diastasis. We have identified four types fracture. Type I injuries demonstrate straight lateral fibular subluxation plastic deformation fibula are best open reduction, removal any interposed soft tissue, stabilization tibiofibular screw. II present due to distal may require osteotomy for prior internal fixation. Plastic as cause has not been previously reported. uncommon III injury consists posterior rotatory fibula. In IV talus dislocated superiorly, resulting divergence tibia usually closed manipulation plaster immobilization. authors two patients Both required restore normal relationship. Good results were obtained patients. Fair secondary stiffness pain activity All maintained mortise following
