- Abstract:
- Objective To compare the imaging results of Salter pelvic osteotomy with proximal femur osteotomy or non-osteotomy for residual acetabular dysplasia (RAD) and examine the necessity of proximal femoral osteotomy.Methods From January 2018 to December 2018,clinical data were retrospectively reviewed for 28 RAD children (32 hips) undergoing Salter pelvic osteotomy.They were assigned into two groups of A and B.Group A:proximal femoral osteotomy group (n=14,15 hips),left hip (n=8),right hip (n=7),right hip (n=7),double hip (n=1);group B:femoral non-osteotomy group (n=14,17 hips),left hip (n=7),right hip (n=10),double hip (n=3).The imaging follow-up data of two groups were compared.The relevant measurement parameters included acetabular index (AI),c/b ratio,head-tear drop distance,coverage rate of head & acetabulum and central marginal angle (centre-edge angle of Wiberg,CEA).Results The average follow-up period was (19.20±8.99) months in group A and (28.88±7.81) months in group B (t=3.259,P=0.003).improvement of AI before and at the last follow-up was ΔAI,(15.77±2.01)° in group A and (15.43±2.99)° in group B (t=-0.372,P=0.712);last CEA,(33.72±6.53)° in group A and (31.72±8.64)° in group B (t=-0.730,P=0.47);c/b ratio,(0.68±0.47) in group A and (0.70±0.44) in group B (t=1.257,P=0.218);head-tear drop distance was (10.70±1.62) in group A and (11.78±0.87) in group B (t=2.380,P=0.024);During the last follow-up,head coverage percentage was (96.45±4.23)% and (88.93±12.27)% (t=-2.250,P=0.032);During follow-ups,there was no re-dislocation.According to the Severin classification,the excellent/good rates of two groups were 93.33%(14/15) and 76.47%(13/17)(χ2=1.719,P=0.190).Conclusion During Salter pelvic osteotomy for RAD,simultaneous proximal femoral osteotomy is not required.
