OBJECTIVE
To compare the differences in acetabular position during total hip arthroplasty (THA) between by direct anterior approach and by posterolateral approach.
METHODS
Between December 2008 and December 2015, 102 patients undergoing THA were included in the study. THA was performed by anterior approach in 51 cases (anterior group) and by posterolateral approach in 51 cases (posterolateral group). There was no significant difference in gender, age, body mass index, side, and cause of illness between 2 groups ( >0.05), with comparability. The acetabular abduction angle and anteversion angel were measured on the X-ray film at 1 day after operation to evaluate whether the acetabular prosthesis was displaced in the safe zone.
RESULTS
The acetabular abduction angle was (42.28±5.77)° in the anterior group and was (43.93±7.44)° in the posterolateral group, showing no significant difference ( =1.30, =0.19). The acetabular anteversion angle was (21.14±5.17)° in the anterior group and was (21.05±4.10)° in the posterolateral group, showing no significant difference ( =0.05, =0.96). The ratio in the target safe zone of the acetabular abduction angle in the anterior group and the posterolateral group were 88.2% (45/51) and 84.3% (43/51) respectively, showing no significant difference ( =0.33, =0.56). The ratio in the target safe zone of the acetabular anteversion was 80.4% (41/51) in the anterior group and was 82.4% (42/51) in the posterolateral group, showing no significant difference between 2 groups ( =0.06, =0.79). The ratio in the target safe zone of both the abduction and anteversion angel was 70.6% (36/51) in the anterior group and was 68.6% (35/51) in the posterolateral group, showing no significant difference ( =0.05, =0.82).
CONCLUSION
There is no differences in the acetabulum position during THA between by direct anterior approach and posterolateral approach.
目的
比较全髋关节置换术（THA）中直接前路与后外侧路髋臼位置的差异。
方法
2008年12月至2015年12月，纳入102例行THA的患者。51例采用前路手术（前路组），51例采用后外侧路手术（后外侧组）。两组在性别、年龄、体重指数、手术侧别及病因方面差异无统计学意义（P>0.05），具有可比性。术后1天通过X线片测量髋臼外展角和前倾角，评估髋臼假体是否位于安全区内。
结果
前路组髋臼外展角为（42.28±5.77）°，后外侧组为（43.93±7.44）°，差异无统计学意义（t=1.30，P=0.19）。前路组髋臼前倾角为（21.14±5.17）°，后外侧组为（21.05±4.10）°，差异无统计学意义（t=0.05，P=0.96）。前路组和后外侧组髋臼外展角在目标安全区内的比例分别为88.2%（45/51）和84.3%（43/51），差异无统计学意义（χ²=0.33，P=0.56）。前路组髋臼前倾角在目标安全区内的比例为80.4%（41/51），后外侧组为82.4%（42/51），两组间差异无统计学意义（χ²=0.06，P=0.79）。前路组髋臼外展角和前倾角均在目标安全区内的比例为70.6%（36/51），后外侧组为68.6%（35/51），差异无统计学意义（χ²=0.05，P=0.82）。
结论
THA中直接前路与后外侧路在髋臼位置上无差异。
