通过对髋臼三维记忆内固定系统在髋臼后壁骨折伴髋臼关节后脱位中临床应用效果的分析，了解其治疗髋臼后壁骨折伴髋臼关节后脱位的可行性与特点。研究发现，其在固定时间及术后功能恢复等方面较之重建钛板内固定都具有明显的应用优势。%BACKGROUND:Posterior wal fractures of the acetabulum with posterior dislocation of the acetabular joint mostly require the operation of open reduction and internal fixation. Different materials can be chosen for internal fixation operation. OBJECTIVE: To explore the effect of acetabular three-dimensional memory fixation system on acetabular posterior wal fractures accompanying the acetabulum joint dislocation. METHODS: A retrospective analysis was performed on clinical data of 92 cases of acetabular posterior wal fracture and dislocation at the Heze Municipal Hospital of Shandong Province from February 2010 to February 2014. Al patients received the operation of open reduction and internal fixation. They were divided into three-dimensional memory fixation group (45 cases) and reconstruction titanium plate group (47 cases) according to different fixators. Al patients were folowed up for 12 months after fixation. RESULTS AND CONCLUSION:The operation time and intraoperative blood loss were significantly longer or higher in the reconstruction titanium plate group than in the three-dimensional memory fixation group (P < 0.05). Harris score was significantly greater in the three-dimensional memory fixation group than in the reconstruction titanium plate group during final folow-up (P < 0.05). Thromboembolic complications or deep infection were not detected after fixation in both groups. These findings confirm that three-dimensional memory fixation system obtained good effects in the treatment of the posterior wal fractures of the acetabulum with posterior dislocation.
