Abstract: Objective To analyze the operative treatment results and complications of the involved articulation calcaneal fracture.Methods From April of 2003 to April of 2007,titanic calcaneal anatomy plate was applied to treat 23 cases of comminuted calcaneal fracture involved posterior sub-talar joint with a lateral approach for the reduction.Results All patients were followed up for an average of 23 months.The data were evaluated with Mayland foot score,the excellent or good rates were 83.3% in Sanders Ⅱ type,88.9% in type Ⅲ,and 50% in type Ⅳ.The primary operative complications derived from the wound were skin necrosis rate at 8.7% and infection rate at 4.3%.Conclusion For the SandersⅡ or Ⅲ calcaneal fracture,treatment with a titanic anatomy plate can receive perfect results.The operative timing should depend on the situation of the soft tissue to avoid post-operative complications.
