[Anterolateral minimally-invasive total hip arthroplasty: a clinical comparative study of 110 cases].
OBJECTIVE To explore the indications and key points of anterolateral minimally-invasive total hip arthroplasty . METHODS 110 baseline indexes matched patients admitted for unilateral total hip arthroplasty were r and omly assigned to 2 equal groups to undergo surgery through a short anterolateral incision of < or = 10 cm or a st and ard posterolateral incision . All operations were done by the same surgeon . The demographic data , perioperative indexes , and postoperative function indexes were recorded and statistically analyzed . RESULTS No significant differences were detected with respect to operation time , abduction angle , anteversion angle , stem alignment , and stem fixation between these 2 groups . The incision length , blood loss , perioperative transfusion , and 100 - mm visual analogue pain scale ( VAS ) score at the first 24 hours of the anterolateral approach group were ( 7.49 + /- 0.86 ) cm , ( 376.18 + /- 168.30 ) ml , ( 410.09 + /- 136.46 ) ml , and ( 30.76 + /- 21.77 ) respectively , all significantly shorter , less , or lower than those of the st and ard posterolateral approach group [ ( 15.2 + /- 1.8 ) cm , ( 605.0 + /- 225.1 ) ml , ( 629.5 + /- 232.9 ) ml , and ( 50.3 + /- 13.7 ) respectively , all P < 0.01 ] . The Harris hip score and Barthel index 3 months after operation of the anterolateral approach group were ( 83.80 + /- 5.64 ) and ( 93.45 + /- 6.37 ) respectively , both significantly higher than those of the st and ard posterolateral approach group [ ( 75.0 + /- 7.5 ) and ( 94.6 + /- 7.5 ) respectively , both P < 0.01 ) ] , however , there were not significant differences in the Harris hip score and Barthel index 3 years after operation between these 2 groups . CONCLUSIONS Fewer traumas , less blood loss and rapid recovery can be obtained through this new total hip arthroplasty approach . But experienced doctors and special instruments are prerequisite
