目的探讨不同分型桡骨小头骨折的治疗策略。方法回顾分析1999年11月至2009年12月我们收治的80例桡骨小头骨折患者的临床资料，其中保守治疗12例（均为MasonI型）；切开复位内固定治疗48例（MasonI型4例，MasonII型15例，MasonⅢ型24例，MasonIV型5例）；桡骨小头切除12例（MasonHI型4例，MasonIV型8例）；桡骨小头置换8例（均为MasonIV型）。结果随访1．0—4．1年，按照Mayo肘关节功能评分评价其疗效，保守治疗优良率为83．3％（10／12），切开复位内固定优良率为87．5％（42／48），桡骨头切除优良率为75．0％（9／12），人工假体置换优良率为100．0％（8／8）。结论MasonI型桡骨小头骨折可以采用保守治疗；MasonII型、MasonⅢ型和部分MasonIV型骨折可以采用切开复位内固定治疗；对于部分MasonIV型骨折无法通过内固定达到稳定固定者可以选择单纯桡骨头切除或人工桡骨头假体置换。

英文摘要：

Objective To evaluate the treatment of radial head fracture of different type. Methods The clinical data of 80 radial head fracture cases from November, 1999 to December,2009 were collected and analyzed retrospectively. Among the 80 cases,12 cases received conservative treatment（all type Mason I ） ;48 cases received open reduction internal fixation （ORIF） （4 case type Mason I ,15 cases type Mason II ,24 cases type Mason Ⅲ, 5 cases type Mason Ⅳ ） ;12 cases received removing radial head （ 4 cases type Mason Ⅲ and 8 cases type IV ）. 8 cases received artificial joint replacement （8 cases type Mason IV ）. Results All cases were followed up for 1.0 -4.1 years. According to the Mayo Elbow Performance Index, the excellent and good rate of treatment in nonoperative, ORIF, excision of the radial head as well as artificial joint replacement was 83.3 % （ 10/12 ） ,87.5 % （42/48 ） ,75.0% （9/12） and 100. 0% （ 8/8 ）, respectively. Conclusions Conservative treatment can be selected for type Mason I ;Open reduction and internal fixation can be selected for type Mason Ⅱ , type Mason m and part of type Mason IV. The excision of radial head or mental prosthesis replacement is alternative for type Mason IV for those can not be treated with open reduction and internal fixation.
