Ossified Posterior Longitudinal Ligament

Background: To assess respiratory function in cervical chronic compressive myelopathy (CCM) patients in pre-operative period, post-operative period and to compare pre-operative status with post-operative status. Aims and Objectives: 1. To assess respiratory function in cervical CCM patients in pre-operative period. 2. To assess respiratory function in cervical CCM patients in post-operative period, following relief of compression. 3. To compare, pre-operative status with post-operative status. Materials and Methods: A prospective study was done in 50 patients with cervical CCM due to either cervical disc disease or ossified posterior longitudinal ligament (OPLL) who were operated. None of the patients included in the study had any clinical signs & symptoms of respiratory dysfunction. Spirometry was performed in pre-operative and postoperative period after 3 months and results were analyzed. Forced vital capacity (FVC), forced expiratory volume in first second (FEV1), ratio of mean FEV1 to FVC (FEVI: FVC%) and peak expiratory flow rate (PEFR) were calculated. Results: Majority of the patients were in their fourth decade of life with male predominance. Thirty-six patients (72%) presented with prolapsed intervertebral disc and 14 patients (28%) had ossified posterior longitudinal ligament (OPLL). Patients were operated depending upon the pathology. The present study showed that there was significant reduction in preoperative FVC, FEV1, PEFR values as compared with predicted values and they showed significant improvement in post-operative period after surgical relief of compression. Conclusion: Significant yet occult respiratory dysfunction in form of impairment of various lung capacities exists in patients with cervical CCM. An objective evaluation of this occult respiratory dysfunction is essential to prognosticate, prevent respiratory complications and to improve post-operative respiratory rehabilitation. Institution of incentive spirometry as a routine in all cervical CCM cases will be of benefit in preventing respiratory complications.

Ossified Posterior Longitudinal Ligament

Background: The most common cause of radiculopathy or myelopathy is “ossification of the posterior longitudinal ligament (OPLL)”. Surgical management consists of various anterior and posterior procedures. Anterior procedures done are corpectomy and fusion. Posterior procedures include laminectomy and laminectomy with fusion that include the use of lateral mass or pedicle screws with rods. Objective was to study the clinical course and to delineate clinico-radiological prognostic factors with regard to surgical outcome.Methods: Patients operated for cervical OPLL were included. Detailed clinical history and radiological findings were retrospectively taken from the case records of the patients and prospectively recorded in the cases operated till May 2018. A minimum follow-up of 6 months was done for improvement. Preoperative clinical evaluation was done. Surgical options were individualized for each patient. Detailed clinical evaluation was done at discharge and at follow-up.Results: It has been found that those patients who were admitted with Nurick’s myelopathy grade IV and V at admission, those with higher number of levels involved like 5, 6 and 7, those with duration of symptoms of more than one year were more likely to have same or deteriorated outcome compared to their counterparts. Other parameters were not found to be significantly associated with outcome.Conclusions: Duration of symptoms >12 months, Sphincter disturbances were significant poor clinical prognostic markers. Significant poor radiological prognostic markers were segmental stenotic index <0.4, MRI T2-Weighted hyper intense signal change.
