Abstract:
Objective:To investigate the effect of periacetabular osteotomy (PAO) assisted by preoperative 3D printing planning on the treatment of early developmental dislocation of the hip (DDH).Methods:A retrospective study was conducted of the 39 patients (44 hips) with CROWE type Ⅰ DDH who had been treated at Department of Orthopaedics, Guizhou Provincial People＇s Hospital from May 2015 to April 2019. In the observation group of 19 patients (22 hips) who were treated by PAO assisted by preoperative 3D printing planning, there were 4 males (4 hips) and 15 females (18 hips) with a mean age of 23(19, 39) years; in the control group of 20 patients (22 hips) who were treated by mere PAO, there were 2 males (2 hips) and 18 females (20 hips) with a mean age of 23(20, 29) years. The 2 groups were compared in terms of operation time, intraoperative bleeding, hospital stay, fluoroscopic frequency, Wiberg lateral center-edge angle (LCE), acetabular index (AC), acetabulum coverage rate, Harris hip scores (HHS) and complications at the final follow-up.Results:There were no significant differences between the 2 groups in their preoperative general data, showing compatibility of the 2 groups ( P>0.05). Both groups were successfully followed up for 6 to 12 months (mean, 9.6 months). The operation time [100 (90, 120) min], intraoperative bleeding [160 (150, 180) mL], hospital stay [6 (5, 7) d], and fluoroscopic frequency [24 (22, 25) times] in the observation group were all significantly better than those in the control group [140 (100, 157) min, 200 (180, 250) mL,9(7, 11) d and 28 (24, 32) times] in the control group ( P<0.05). However, there were no significant differences between the 2 groups in LCE, AC or acetabulum coverage rate immediately after operation, or in HHS or complications at the final follow-up( P>0.05). Conclusions:Although PAO has a definite therapeutic effect on early DDH, PAO assisted by preoperative 3D printing planning can effectively reduce operation time, intraoperative bleeding, hospital stay and intraoperative fluoroscopy. Thus, combination of the two can result in a better therapeutic effect than PAO alone.
