Objective :To investigate clinical outcomes of the internal fixation of calcaneal plate in the treatment of Sanders Ⅲ 、Ⅳ calcaneal fractures .Methods :A retrospective analysis from January 2006 to March 2011 ,a total of 49 ca-ses including 51 feet were treated with calcaneal plate .According to Sanders classification :38 feet of Ⅲ ,13 feet of Ⅳ . The postoperative outcomes were evaluated according to Maryland scoring system ,Bohler angle ,Gissane angle and vis-ual analogue scale(VAS) .Results:All patients were evaluated .The mean followed up time was 11 month(range 8~18 month) .According to Maryland scoring system :excellent in 14 feet ,good in 29 patients ,moderate in 7 feet ,and poor in 1 foot .The excellent and good rate was 76 .9% .The rate indicated in different types :33 cases of Ⅲ :86 .7% .10 cases ofⅣ :76 .9% .There were significant differences in Bohler angle ,Gissane angle and visual analogue scale in preoperative , postoperative and follow up comparison (P<0 .05) .Conclusion:Calcaneal fractures could be treated successfully with calcaneal plate by lateral surgical approach ,making the postoperative Bohler angle and Gissane angle get a better recov-ery ,as well as the pain and joint function after the injury ,which is one of the ideal methods for calcaneal fractures of Sanders Ⅲ and above .% 目的：探讨跟骨钢板内固定技术治疗SandersⅢ、Ⅳ型跟骨骨折的临床疗效。方法：回顾性分析2006年1月-2011年3月采用跟骨钢板内固定治疗的病例，共49例51足，其中Sanders分型Ⅲ型38足、Ⅳ型13足，随访时采用Maryland足部评分系统评价术后疗效以及Bohler角、Gissane角和疼痛视觉模拟评分（VAS评分）。结果：所有患者均得到随访，平均随访11个月（8～18个月），根据M aryland足部评分系统：优14足，良29足，可7足，差1足，优良率84．3％。优良率在不同类型骨折中分别为：Ⅲ型33例，占该型86．8％；Ⅳ型10例，占该型76．9％；对术前、术后和随访的Bohler角、Gissane角、VAS评分等因素比较，差异有统计学意义（P＜0．05）。结论：跟骨骨折进行外侧入路手术跟骨钢板复位内固定治疗，得到良好的临床效果，术后Bohler角及Gissane角得到良好的恢复，疼痛明显改善，伤后关节功能恢复好，是治疗SandersⅢ型及以上的跟骨骨折理想方法之一。
