Summary: OPLL can result in symptoms such as hand clumsiness and impaired gait, as demonstrated in this case study. The patient presented with signs of spinal cord compression, and imaging showed seesaw-like OPLL, indicating laminoplasty and laminectomy may not be the most suitable treatment options.

Summary: This study aimed to investigate the surgical efficacy of crossing the cervicothoracic junction during posterior cervical laminectomy and fusion for the treatment of multilevel cervical ossification of the posterior longitudinal ligament (OPLL). The results showed that this method is safe and effective, improving both clinical symptoms and radiographic outcomes in patients.

Summary: LF shows better prevention of OPLL growth compared to LP, but LP has superior postoperative neurological recovery, lower complication rate, and fewer reoperations.

Summary: This study compared the outcomes of expansive open-door laminoplasty with instrumented fusion (ELIF) and expansive open-door laminoplasty with instrumented non-fusion (ELINF) for multilevel cervical ossification of the posterior longitudinal ligament (OPLL). The results showed that ELIF was superior to ELINF, especially for patients with K-line ( - ) OPLL.

Summary: The study summarized 30 studies involving 2038 patients, indicating that ACCF had superior Japanese Orthopaedic Association scores compared to LP and LF. ACAF procedures resulted in significantly better cervical lordosis compared to ACCF, LP, and LF. Both ACAF and LP had lower complication rates compared to ACCF.

Summary: This study compared the cervical alignment and clinical outcomes in patients with cervical ossification of the posterior longitudinal ligament (OPLL) who underwent laminectomy with instrumented fusion ending at different levels. It was found that terminating at C-6 was recommended for elderly patients with great preoperative sagittal vertical axis to limit muscle invasion. Factors such as age, preoperative SVA, and NDI score were associated with postoperative imbalance.

Summary: Most studies on OPLL ossification using the finite element method have been conducted in the neutral state, which does not reflect the actual behavior of the cervical spine. This study conducted a biomechanical analysis during flexion and extension behaviors and found that spinal cord decompression did not work well in these movements. Therefore, additional surgery using an anterior approach should be considered for patients with focal OPLL who require posterior decompression.

Summary: Surgeons can choose either side for cervical unilateral open door laminoplasty (UODL) according to their preference, as the choice of lamina opening side does not significantly affect postoperative outcomes in terms of radiographic and clinical parameters or the incidence of C5 palsy.

Summary: The study aimed to evaluate the influence of the K-line on the outcome of open-door laminoplasty versus anterior cervical corpectomy decompression and fusion (ACCF) for patients with more than two levels of ossification of the posterior longitudinal ligament (OPLL). The results showed that for cases with K-line (+) and K-line (-), the improvement rate of JOA scores after posterior approaches was 72.4% and 53.1% respectively, with a significant difference. For patients with K-line (+), open-door laminoplasty provided the same neurologic function recovery as ACCF.

Summary: In the study on anterior decompression with fusion for the treatment of cervical ossification of the posterior longitudinal ligament, the number of operated levels was found to be significantly associated with postoperative complications, especially in cases with four or more levels involved.

Summary: This retrospective observational study evaluated the long-term recurrence rates and functional status of patients with thoracic ossification of the posterior longitudinal ligament (OPLL) after decompression and posterior fusion surgery. The study found that while the surgery had stable long-term clinical outcomes, late neurological deterioration was observed in some patients outside of the primary operative lesion. Factors such as young age, high body mass index, and lumbar OPLL were associated with this deterioration.

Summary: This study explored the effect of open-door laminoplasty and simultaneous C2 semi-laminectomy with lateral mass screw fixation (LSLF) in treating ossification of the posterior longitudinal ligament (OPLL) in cervical discs at C2 segment. The results showed that LSLF could better improve neck functions, reduce the severity of axial symptoms, and decrease the occurrence of C5 palsy compared to laminectomy and lateral mass screw fixation (LF) in patients with OPLL at C2 segment.

Summary: This study investigated the postoperative dysphagia in cervical posterior longitudinal ligament ossification (C-OPLL) and cervical spondylotic myelopathy (CSM) to identify the risk factors of each disease and the incidence. The results showed that increased angle C2-7 was a risk factor for both diseases.
