Many joint-depressive, neglected calcaneal fractures need distraction arthrodesis of the subtalar joint. Because the calcaneal tuberosity is usually malunited in the varus position, more distraction is required on the medial side to place the tuberosity in the everted position before insertion of a bone graft. Traditionally, a distractor is placed on the medial side to achieve this task. However, the medially placed distractor hinders with the positioning of the extremity and exposure of the main operative site, which is commonly on the lateral side. We introduce a technique to avoid this burden by placing a hinged distractor device on the lateral aspect of the foot while maintaining the correction of the varus deformity.
许多合并关节面塌陷、被忽视的跟骨骨折需要进行距下关节撑开融合术。由于跟骨结节通常在内翻位畸形愈合，在植入骨 graft 之前，需要在内侧施加更多的撑开力，以便将结节置于外翻位。传统上，在内侧放置撑开器来完成这项任务。然而，放置在内侧的撑开器会妨碍肢体的定位和主要手术部位（通常在外侧）的显露。我们介绍一种技术，通过在足外侧放置一个铰链式撑开器装置来避免这种负担，同时保持对内翻畸形的矫正。
