Abstract:
Objective To investigate the clinical effect of anterograde percutaneous screw fixation under robot navigation in the treatment of acetabular anterior column fractures.Methods A retrospective analysis was made on 7 cases of anterior acetabular column fractures from April 2021 to January 2023.The traction reduction was conducted by using pelvic"double reverse"traction table,the orthopedic robot-assisted design was carried out to plan the screw entry point and direction,and the antegrade channel cannulated screw was used for internal fixation.Results The operation time was 60-95 min(mean,78 min).The intraoperative blood loss was 5-20 ml(mean,8.6 ml).The number of fluoroscopy was7-11(mean,8.7).The guide needle was unadjusted in 3 cases and adjusted for 1-2 times in 4 cases(once in 2 cases and twice in 2 cases).The actual path deviated from the planned by 0.65-1.50 mm(mean,0.98±0.30 mm).The excellent and good rate of screw position was 100%.X-ray and CT examinations were performed at 48 h after the operation.According to the Matta reduction standard,anatomical reduction was achieved in 6 cases and satisfactory reduction in 1 case.All the 7 cases were followed up for 6-28 months(mean,15 months).At the last follow-up,the Harris score of the hip joint was85-96 points(mean,91.6 points)and the pain of visual analogue scale(VAS)was0.There were no complications such as infection,loosening of internal fixation,or neurological dysfunction.Conclusion Anterograde percutaneous screw fixation under robot navigation in the treatment of acetabular anterior column fractures is safe,effective,and satisfactory.
