![]() ![]() The early detection of this fracture is difficult. We suggest CT and MRI as excellent imaging modalities that can help the timely diagnosis and appropriate treatment for this combined impingement with circumferential lesions.įracture of posteromedial tubercle of talus (PMTT), first described by Cedell in 1974, is an uncommon injury caused by dorsiflexion-pronation of the foot and ankle as the posterior talotibial ligament is torn from its attachment to the talus. To fully recognize this occult lesion and avoid missing is imperative for reducing the morbidities. To our knowledge, this was the first reported case with anterior, posterior and posteromedial impingement which was treated operatively with an excellent short-term outcome. The AOFAS hindfoot score was 90 at 1 year follow-up. We reported a 58-year-old female with combined anterior and posterior ankle impingement syndrome with nonunion of Cedell fracture in whom open osteophytes debridement, fracture internal fixation and posterior talotibial ligament reconstruction were performed. But the concurrent lesion of both of them has not been reported. The injury mechanisms and management strategies of these two lesions have been reported individually. Cedell fracture, fracture of posteromedial tubercle of talus, is an uncommon and easily missed injury which may elicit posteromedial ankle impingement. Combined anterior and posterior ankle impingement has seldom been reported. ![]()
