During a 4-year period, 35 nonconsecutive intraarticular fractures of the calcaneus were fixed with 2.7-mm minifragment plates and 3.5-mm small fragment screws through an extended lateral approach. There were 25 type II and 10 type III fractures by the classification system of Sanders. The reduction of the facet was anatomic in 91%. The reduction of the tuberosity was acceptable (< or = 5 degrees of angulation) in all cases. Early motion was begun in the ankle, subtalar, and midfoot joints in all cases. Two patients had minor edge necrosis amenable to local treatment. There were no deep infections. Using the Maryland foot score, there were 77% good or excellent results. The small size of the minifragment plates allows for their application to a wide variety of fracture patterns. They are also low profile and are therefore easy to cover. Multiple plates were used in many cases without steric interference. They provided rigid enough fixation to allow aggressive early motion exercises without loss of reduction or hardware failure in any case. Minifragment plates with small fragment screws are effective for the fixation of intraarticular calcaneus fractures through an extended lateral approach.
在4年期间，通过延长外侧入路，使用2.7毫米微型接骨板和3.5毫米小骨块螺钉固定了35例非连续性跟骨关节内骨折。根据Sanders分类系统，其中有25例II型骨折和10例III型骨折。91%的关节面复位达到解剖复位。所有病例中结节的复位均可接受（成角≤5度）。所有病例均在踝关节、距下关节和中足关节早期开始活动。2例患者出现轻微边缘坏死，可进行局部治疗。无深部感染。采用马里兰足部评分，77%的结果为良好或优秀。微型接骨板尺寸小，可应用于多种骨折类型。它们的外形也很低，因此易于覆盖。许多病例中使用了多个接骨板，没有空间干扰。它们提供了足够牢固的固定，使患者能够积极进行早期活动锻炼，在任何情况下都不会出现复位丢失或内固定失败。带小骨块螺钉的微型接骨板通过延长外侧入路固定跟骨关节内骨折有效。
