Addition of posterior instrumented fusion to laminoplasty (posterior decompression with instrumented fusion: PDF) can improve the surgical outcome of patients with K-line (-) cervical ossification of the longitudinal ligament (OPLL) compared with laminoplasty alone. We sought to elucidate the factors that are significantly associated with a better outcome after PDF for K-line (-) OPLL. ⋯ Postoperative K-line conversion from (-) to (+) is a factor independently associated with a better surgical outcome.

The purpose of this research is to compare the clinical efficacy, postoperative complication and surgical trauma between anterior cervical corpectomy and fusion versus posterior laminoplasty for the treatment of oppressive myelopathy owing to cervical ossification of the posterior longitudinal ligament (OPLL). ⋯ In summary, when the preoperative canal occupying ratio < 60%, no palpable difference was tested in postoperative JOA score and neurofunctional recovery rate. But, when the preoperative canal occupying ratio ≥ 60% ACCF was associated with better postoperative JOA score and the recovery rate of neurological function compared with LAMP. Synchronously, ACCF in the cure for cervical myelopathy owing to OPLL led to more surgical trauma and more incidence of complication and reoperation. On the other hand, LAMP had gone a diminished postoperative C2-C7 Cobb angle, that might be a cause of relatively higher incidence of postoperative late neurofunctional deterioration. In brief, when the preoperative canal occupying ratio < 60%, LAMP seems to be effective and safe. However, when the preoperative canal occupying ratio ≥ 60%, we prefer to choose ACCF while complications could be controlled by careful manipulation and advanced surgical techniques. No matter which option you choose, benefits and risks ought to be balanced.

The Neck Disability Index (NDI) is used to evaluate patients with cervical spine disease. However, few reports have defined the cut-off values of the NDI. The purpose of this study was to identify the cut-off values of and factors with a negative impact on NDI. ⋯ Deterioration in NDI was associated with cervical spinal malalignment and manual labor in males and lack of physical activity and sarcopenia in females.
