OBJECTIVE: To evaluate the effectiveness of posterior @entity1171 fixation on the function of ankle in @entity1 with @entity1171 . METHODS: Between June 2007 and June 2009, 110 @entity1 with @entity1171 were treated with posterior @entity1171 fixation in 59 @entity1 (fixation group) or without fixation in 51 @entity1 (non-fixation group). In fixation group, there were 31 males and 28 females with an average age of 62.6 years (range, 19-75 years); the causes of injury included traffic accident (20 cases), falling (18 cases), and @entity6475 (21 cases) with a disease duration of 1-3 days (2.2 days on average); and the locations were left ankle in 32 cases and right ankle in 27 cases, including 6 cases of type I, 23 of type II, 19 of type III, and 11 of type IV according to the @entity1171 classification. In non-fixation group, there were 38 males and 13 females with an average age of 64.5 years (range, 16-70 years); the causes of injury included traffic accident (15 cases), falling (12 cases), and @entity6475 (24 cases) with a disease duration of 1-3 days (2.5 days on average); and the locations were left ankle in 22 cases and right ankle in 29 cases, including 8 cases of type I, 16 of type II, 19 of type III, and 8 of type IV according to the @entity1171 classification. There was no significant difference in general data between 2 groups (P > 0.05). RESULTS: All @entity1 of 2 groups achieved wound healing by first intention. The @entity1 were followed up 12-18 months (16 months on average). X-ray films showed that @entity174 healed at 8-12 weeks (10 weeks on average) in fixation group and at 10-14 weeks (12 weeks on average) in non-fixation group. There were significant differences in the clinical score (89.28 +/- 8.62 vs. 86.88 +/- 9.47, P < 0.05), postoperative reposition score (33.34 +/- 2.15 vs. 31.24 +/- 2.89, P < 0.05), and @entity571 score (13.22 +/- 1.66 vs. 12.46 +/- 2.03, P < 0.05) according to Phillips ankle scoring system between 2 groups at last follow-up. There was no significant difference in clinical score of type I and II @entity1 between 2 groups (P > 0.05), but significant differences were found in clinical score and @entity571 score of type III and IV @entity1 between 2 groups (P < 0.05). There were significant differences in the postoperative reposition score between 2 groups in all types of @entity174 (P < 0.05). CONCLUSION: The posterior @entity1171 fixation may provide satisfactory clinical functional outcomes for @entity1171 . Proper @entity174 classification and correct method of internal fixation are important for achieving good reduction and improving the long-term results.
