The aim of this study is to present our technique for a large focal correction of a partially flexible dropped head deformity through combined anterior and posterior osteotomies, as well as anterior soft tissue releases.
One patient with dropped head deformity underwent an anterior and posterior osteotomy with anterior soft tissue release.
The patient recovered well, with postoperative radiographs demonstrating significant improvement in coronal and sagittal alignment. His C2-C7 sagittal vertical axis improved from 7.5 cm preoperatively to less than 4 cm postoperatively and his C2-C7 sagittal Cobb improved from 35° of kyphosis to 10° of lordosis.
In this report, we present our technique for a large focal correction of a partially flexible dropped head deformity through combined anterior and posterior osteotomies and anterior soft tissue releases. These more conservative osteotomies permitted gradual deformity correction and alleviated the need for pedicle subtraction osteotomy. We were able to restore horizontal gaze and improve sagittal malalignment. Although the technique we present here is one of many possible options for managing the deformity, we believe this combined approach is safe and effective and well tolerated by patients.
本研究的目的是介绍我们通过前后联合截骨术以及前路软组织松解术对部分柔韧性低头畸形进行大面积局部矫正的技术。
1例低头畸形患者接受了前后截骨术及前路软组织松解术。
患者恢复良好，术后X线片显示冠状面和矢状面排列有显著改善。其C2-C7矢状垂直轴从术前的7.5厘米改善至术后小于4厘米，C2-C7矢状面Cobb角从后凸35°改善至前凸10°。
在本报告中，我们介绍了通过前后联合截骨术和前路软组织松解术对部分柔韧性低头畸形进行大面积局部矫正的技术。这些更为保守的截骨术允许逐步矫正畸形，并减少了椎弓根截骨术的必要性。我们能够恢复水平注视并改善矢状面排列不齐。虽然我们在此介绍的技术是处理该畸形的众多可能选择之一，但我们认为这种联合方法是安全有效的，且患者耐受性良好。
