Abstract：Objective To evaluate the clinical effects of direct anterior approach ( DAA ) for total hip arthroplasty in the treatment of Crowe I, II type of hip dysplasia.Methods From June 2012 to October 2015, 47 cases of Crowe I, II type developmental dysplasia of the hip were treated with total hip arthroplasty, including the lateral approach group 27 cases ( 27 hips ) and the direct anterior approach group 20 cases ( 20 hips ). The operative incision length, operative time, intraoperative bleeding, Harris hip score preoperatively, 1 week postoperatively, 1 month postoperatively, 3 months postoperatively, 6 months postoperatively were analyzed. Prosthesis position of and complications 6 months postoperatively were observed.Results Operative incision length: DAA approach group ( 8.97 ± 1.030 ) cm, lateral approach group ( 14.37 ± 1.043 ) cm, statistically signiifcant ( P < 0.05 ). The intraoperative bleeding: DAA approach group ( 245.00 ± 37.906 ) ml, lateral approach group ( 384.07 ± 50.020 ) ml, statistically significant (P< 0.05 ); Harris hip score 1 week postoperatively: DAA approach group ( 71.15 ± 7.962 ), lateral approach group ( 64.63 ± 5.336 ), statistically signiifcant ( P < 0.05 ); Harris hip score 1 month postoperatively: DAA approach group ( 79.80 ± 4.916 ), lateral approach group ( 72.67 ± 4.446 ), statistically signiifcant ( P < 0.05 ); Harris hip score 3 months postoperatively: DAA approach group ( 89.80 ± 3.270 ), lateral approach group ( 84.48 ± 3.916 ), statistically signiifcant (P< 0.05 ). The operation time, angle of prosthesis, Harris hip score 6 months postoperatively showed no significant statistical differences ( P > 0.05 ). Greater trochanter pain occurred in 1 case, subcutaneous hematoma occurred in 1 case, and blood transfusion was applied in 21 cases in the lateral approach group. Femoral lateral cutaneous nerve injury symptom occurred in 2 cases and blood transfusion was applied in 5 cases in the direct anterior approach group.Conclusions Compared with the conventional approach, DAA has advantages of small incision, less bleeding, quicker recovery and so on, but the long-term hip joint functions are similar.
