This retrospective study assesses the complications affecting the cervical spine after halo-pelvic traction in 83 patients who were followed up for a minimum of five years. Forty-four patients (53 per cent) had significant cervical complications such as radiological degenerative changes, avascular necrosis of the dens, loss of movement, pain or spontaneous fusion. The most important predisposing factors were a long period in the halo-pelvic apparatus, tuberculous kyphosis, stiffness of the spinal deformity and an age of 15 years or more at the time of application.
这项回顾性研究评估了83例接受了至少五年随访的患者在头环骨盆牵引后影响颈椎的并发症。44例患者（53%）出现了严重的颈椎并发症，如影像学上的退行性改变、齿状突缺血性坏死、活动度丧失、疼痛或自发融合。最重要的诱发因素是使用头环骨盆装置的时间较长、结核性后凸、脊柱畸形僵硬以及应用时年龄在15岁及以上。
