The efficiency of posterior longitudinal ligament （PLL） resection in anterior cervical decompression and fusion has been demonstrated. However, no clinical reports have compared PLL removal with preservation in Bryan cervical disc arthroplasty. This study aimed to assess the role of removal of PLL in Bryan cervical disc arthroplasty at an 18-month follow-up.展开更多
