Abstract:
OBJECTIVE:To explore the application effect of grid locator in hip arthroscopy for the treatment of femoral acetabular impingement (FAI).
METHODS:Total of 50 patients of FAI were treated by arthroscopic hip joint surgery for from January 2020 to January 2021, and were divided into two groups according to intraoperative positioning methods. Among them, 27 cases in the positioner group were treated by hip arthroscopy assisted by grid positioner including 10 males and 17 females with a mean age of (35.91±9.92) years old. In the non-locator group, 23 cases were treated with hip arthroscopy by positioning puncture according to the operator's experience including 12 males and 11 females with a mean age of (36.01±11.03) years old. Intraoperative fluoroscopy times, puncture time, adjusted puncture times and operation time of two groups were compared. The α Angle and lateral central edge(LCE) angle of hip joint were measured and compared before and after operation. Four evaluation indexes were recorded and compared, including pain visual analogue scale(VAS), hip Harris score, non-inflammatory hip joint score (NAHS), hip joint activities of daily living (HOS-ADL).
RESULTS:All patients were followed up for 6 to 12 months with an average of (18.69±3.72) months. The α angle and LCE angle of hip joint at 1 month after operation were decreased in both groups(P<0.05), but there was no significant difference between groups(P>0.05). VAS, hip Harris score, NAHS and HOS-ADL score after operation were higher than those before operation(P<0.05), but there was no statistical significance between groups (P>0.05). Intraoperative fluoroscopy times(6.04±1.13), puncture time(13.19±3.52) min, puncture adjustment times(4.59±1.55) and operation time(48.28±3.38) min in the positioner group were less (shorter) than those of (13.43±2.56), (22.39±2.93) min, (10.43±3.33), (62.25±5.73) min in the non-positioner group(P<0.05). No postoperative complications occurred in both groups, and the pain was significantly relieved.
CONCLUSION:The application of hip arthroscopy in the treatment of femoral acetabular impingement sign can obtain good postoperative results. Compared with the traditional positioning method, the grid locator can improve the accuracy of skin positioning point, shorten the puncture time, reduce the number of fluoroscopy, and improve the efficiency of surgical puncture.
