To describe the clinical setting and pattern of talar insufficiency stress fractures as diagnosed with magnetic resonance (MR) imaging.
The authors retrospectively reviewed the clinical history and MR images from four patients with five talar insufficiency fractures. All patients were women (age range, 30-70 years). Images were evaluated for the location and orientation of fractures and the presence of concomitant osseous and soft-tissue injury.
Concomitant fractures were identified in two patients. Only two fractures were typical in location and orientation at the talar neck. Three fractures were atypical in location and orientation. One occurred horizontally in the talar body and two occurred in the posteromedial talus (one was oriented vertically and one horizontally). Two patients had associated concomitant stress fractures--one in the distal tibia and one in the calcaneus.
The location and orientation of talar insufficiency fractures is more variable than previously recognized. Specific diagnoses and coexisting fractures can be determined with MR imaging.
描述经磁共振成像（MR）诊断的距骨应力性骨折的临床情况及模式。
作者回顾性分析了4例患有5处距骨应力性骨折患者的临床病史及MR图像。所有患者均为女性（年龄范围30 - 70岁）。对图像进行评估，观察骨折的位置、方向以及是否存在合并的骨与软组织损伤。
2例患者合并其他骨折。仅2处骨折在距骨颈的位置和方向上较为典型。3处骨折在位置和方向上不典型。1处骨折水平位于距骨体，2处骨折位于距骨后内侧（1处垂直，1处水平）。2例患者合并有其他应力性骨折，1例在胫骨远端，1例在跟骨。
距骨应力性骨折的位置和方向比之前认识到的更具变异性。通过MR成像可确定具体诊断及并存的骨折情况。
