Treatment choices for unilateral cervical facet locking / 中华创伤杂志

ABSTRACT

Objective To explore different treatment choices for unilateral cervical facet locking. Methods The study involved 32 patients with cervical unilateral facet locking. Successful reduction by the skull traction was done in eight patients, of whom three were fixated by the head and neck chest plas-ter after a month of traction. Five patients were treated with anterior decompression and internal fusion fixation. The other 23 patients resulted in failure of traction and then were treated with anterior reduction, discectomy and internal fusion fixation in 14 patients, subtotal vertebral decompression and bone graft fix-ation in three, posterior open reduction and anterior bone graft fixation in one, posterior reduction, fixation and internal fusion fixation in three and posterior reduction and decompression plus anterior discectomy decompression and bone graft fixation in two. Due to misdiagnosis, one patient was treated with anterior decompression and fusion eight months after injury. Results A follow-up for average 18 months showed cervical instability in two patients who were treated with only traction, without fusion. The patients treated with anterior cervical fusion obtained bone union after 12 weeks, with satisfactory cervical physiological curvature and vertebral height. There were no internal fixation complications or neurological complications. Conclusions The treatment of lower cervical unilateral facet locking needs a compre-hensive considerations on whether there associates with disc injury, posterior column fractures or spinal cord injuries. As for patients with lower cervical unilateral facet locking combined with traumatic cervical disc herniation, the anterior reduction and decompression is the choice of treatment. While for those with-out disc herniation, traction or posterior open reduction and fixation can be carried out directly.
