Traditionally graft displacement following Pemberton and Dega acetabuloplasties involves internal fixation for treatment of developmental dysplasia of hip (DDH). This study was performed to assess the acetabular remodeling by conservative management of graft displacement among patients with DDH. This was a retrospective study of 20 patients 17 (85%) women and 3 (15%) men; mean age 22.90 ± 6.96 months with DDH who underwent Pemberton and Dega acetabuloplasties at King Khalid University Hospital, Riyadh between January 2013 and January 2018. All patients after losing acetabular correction during immediate postoperative period were treated by conservative management. The management involved application of Spica cast for 6 weeks that was trimmed to broomstick cast for an extended period of time and finally replaced by nocturnal abduction brace until normal acetabular index (AI) was achieved. The patients were followed up for a mean period of 44.60 ± 12.36 months. Out of the total, 18 (90%) patients with DDH were successfully treated by conservative management. The mean preoperative AI of 43.70° ± 5.91° improved to 21.35^o ± 6.32^o at the final follow-up (P < 0.001) which was no different when compared to the mean of unaffected hips (19.70^o ± 2.96^o; P < 0.44). The mean preoperative CEA of all the patients was negative that improved during the conservative treatment to 29.20° ± 10.0° which was no different when compared with the mean of unaffected (31.70° ± 4.64^o; P = 0.32) hips at the final follow-up. doption of less aggressive approach for management of displaced, rotated or impacted autograft following acetabuloplasties among children with DDH was not only a useful conservative approach for remodeling of hips but also obviated the need for additional surgical intervention.

传统上，Pemberton 和 Dega 髋臼成形术后的移植物移位包括内固定以治疗发育性髋关节发育不良 (DDH)。本研究旨在通过保守治疗 DDH 患者的移植物移位来评估髋臼重塑。这是对 20 名患者的回顾性研究，其中 17 名 (85%) 女性和 3 名 (15%) 男性；2013 年 1 月至 2018 年 1 月在利雅得哈立德国王大学医院接受 Pemberton 和 Dega 髋臼成形术的 DDH 平均年龄为 22.90 ± 6.96 个月。所有在术后即刻失去髋臼矫正后的患者均接受保守治疗。管理包括使用 Spica 石膏 6 周，并在较长时间内修剪为扫帚石膏，最后更换为夜间外展支架，直至达到正常的髋臼指数 (AI)。对患者的平均随访时间为 44.60 ± 12.36 个月。在总数中，18 名（90%）DDH 患者通过保守治疗成功治疗。平均术前 AI 43.70° ± 5.91° 提高到 21.35^o ± 6.32 ^o在最终随访时 ( P < 0.001)，与未受影响的髋关节的平均值 (19.70 ^o ± 2.96 ^o ; P < 0.44)相比没有差异。所有患者术前平均 CEA 均为阴性，在保守治疗期间改善至 29.20° ± 10.0°，与未受影响患者的平均值（31.70° ± 4.64 ^o ; P= 0.32) 最后一次随访时的臀部。在 DDH 儿童髋臼成形术后，采用较不激进的方法来处理移位、旋转或受阻的自体移植物不仅是一种有用的髋关节重塑保守方法，而且不需要额外的手术干预。
