About this study
Cervical spinal stenosis is a condition that can cause pain, sensory disturbances, and motor deficits due to the compression of neural structures in the cervical spine. While conservative treatments such as physical therapy and pain management can help some patients, others with persistent neurological deficits may require surgical intervention. Traditional surgical approaches, including anterior decompression and posterior open surgery, have proven effective but carry risks such as vascular or nerve injuries and postoperative pain.
This study evaluates a minimally invasive surgical approach called Posterior Uniportal Endoscopic Cervical Decompression as an alternative to traditional methods for patients with cervical spinal stenosis. The main objective is to assess changes in neurological deficits and disability related to cervical pain following this procedure. The study will also document hospitalization duration, surgical time, blood loss, and the incidence of postoperative complications.

This multicenter, prospective case series will recruit 50 patients from three medical centers in Mexico. Participants must have symptomatic cervical spinal stenosis that persists despite at least three months of conservative treatment. Eligible patients will undergo Posterior Uniportal Endoscopic Cervical Decompression, a technique that allows precise nerve decompression through a small incision, minimizing damage to surrounding tissues. Standardized clinical assessment tools, including the modified Japanese Orthopaedic Association (mJOA) scale, Neck Disability Index (NDI), and Visual Analog Scale (VAS) for pain, will be used to evaluate outcomes at multiple time points over 12 months.
By comparing patients' preoperative and postoperative evaluations, the study aims to determine whether Posterior Uniportal Endoscopic Cervical Decompression effectively improves neurological function and reduces disability while maintaining a favorable safety profile. Findings from this study could support the adoption of minimally invasive endoscopic techniques as a viable option for treating cervical spinal stenosis, potentially leading to faster recovery times and reduced surgical complications compared to traditional methods.
Read the detailed description
Cervical spinal stenosis is a condition characterized by the narrowing of the cervical spinal canal, leading to compression of the neural structures. This can cause chronic pain, sensory disturbances, and motor deficits, significantly impairing the quality of life. While conservative management, including physical therapy, analgesics, and steroid injections, can provide symptomatic relief for some patients, others with persistent neurological deficits may require surgical intervention. Traditional surgical techniques, such as anterior cervical decompression and fusion or posterior open decompression, have been effective but carry risks such as vascular injury, neurological complications, and postoperative pain.
This study investigates the use of Posterior Uniportal Endoscopic Cervical Decompression, a minimally invasive surgical approach that offers targeted decompression through a single small incision while minimizing tissue disruption. The primary objective of the study is to evaluate changes in neurological deficits and disability related to cervical pain following this procedure. Secondary objectives include assessing the duration of hospitalization, surgical time, blood loss, and the incidence of postoperative complications.
This multicenter, prospective case series will recruit 50 patients diagnosed with cervical spinal stenosis at three medical institutions in Mexico. The study will be conducted over a period of 24 months, with an initial 12-month patient recruitment phase, followed by postoperative follow-up assessments at predetermined time intervals up to one year.
Participants will undergo Posterior Uniportal Endoscopic Cervical Decompression, a technique designed to preserve spinal mobility while reducing compression on the nerve roots. The procedure will be performed under general anesthesia with continuous neurophysiological monitoring, including somatosensory evoked potentials, motor evoked potentials, and continuous electromyography. Using a working-channel endoscope, surgeons will perform foraminotomies or laminotomies to remove compressive elements such as osteophytes, hypertrophic ligaments, or herniated disc material. The technique is aimed at achieving decompression with minimal disruption to the surrounding soft tissues.
Patients must meet specific inclusion criteria, including an age range of 18 to 75 years, confirmed diagnosis of cervical spinal stenosis (Kang classification grade I-III), and the presence of neurological symptoms unresponsive to at least three months of conservative management. Exclusion criteria include prior cervical surgery at the affected level, active infections, systemic inflammatory diseases, vertebral instability, congenital spinal malformations, and contraindications for general anesthesia.
Patient outcomes will be systematically evaluated using validated clinical assessment tools, including:
- Modified Japanese Orthopaedic Association (mJOA) Scale - to assess neurological function.
- Neck Disability Index (NDI) - to measure the impact of cervical pain on daily activities.
- Visual Analog Scale (VAS) for pain - to quantify cervical and upper limb pain intensity.
- EQ-5D-5L health-related quality of life questionnaire - to evaluate overall well-being.
- Modified MacNab Criteria - to determine patient satisfaction with surgical outcomes.
Descriptive statistical methods will be used to analyze demographic and clinical characteristics of the study population. Changes in primary and secondary outcomes will be evaluated using paired t-tests for continuous variables and Chi-square tests for categorical variables. The impact of the procedure on neurological function and pain relief will be assessed through longitudinal comparisons between baseline and follow-up assessments at 1, 3, 6, and 12 months postoperatively. The incidence of complications will be categorized using the Clavien-Dindo classification, and the Comprehensive Complication Index will be used to quantify cumulative morbidity.
This study complies with the Declaration of Helsinki, the International Council for Harmonisation Good Clinical Practice (ICH-GCP) guidelines, and national regulatory requirements. All participants will provide written informed consent before enrollment, and patient confidentiality will be maintained through data pseudonymization. The study has been approved by the Ethics Committees of the participating institutions.
The expected impact of this study is to generate clinical evidence supporting Posterior Uniportal Endoscopic Cervical Decompression as a safe and effective alternative to traditional surgical approaches for cervical spinal stenosis.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Cervical Disability (Neck Disability Index)
This measure assesses disability related to cervical pain using the Neck Disability Index (NDI), a validated instrument scored from 0 (no disability) to 100 (maximum disability). It quantifies the impact of cervical pain on daily activities and overall function. Changes in NDI scores over time will reflect the effectiveness of the surgical intervention in reducing pain-related disability.
Measured: Baseline; 1 month, 3 months, 6 months, and 12 months postoperatively.
Change in Neurological Function (Modified Japanese Orthopaedic Association Score)
This measure evaluates neurological function using the Modified Japanese Orthopaedic Association (mJOA) scale. The mJOA score, which ranges from 0 (severe neurological deficits) to 18 (normal neurological function), assesses motor function, sensory deficits, and gait. Improvements in the mJOA score following surgery will be used as an indicator of enhanced neurological status.
Measured: Baseline; 1 month, 3 months, 6 months, and 12 months postoperatively.
Secondary outcomes (4)
Duration of Hospitalization
This metric records the total number of days from patient admission until discharge following the surgical procedure. It serves as an indicator of the immediate postoperative recovery and overall efficiency of the surgical intervention.
Measured: Measured during the index hospitalization.
Duration of Surgery
This outcome measures the surgical time, defined as the period from the initial incision to the final closure of the surgical site. It reflects procedural efficiency and may indirectly indicate the technical ease or complexity of the procedure.
Measured: Recorded intraoperatively.
Intraoperative Blood Loss
This measure quantifies the volume of blood lost during the surgical procedure, as collected via standard suction devices and measured in milliliters. It is an important indicator of surgical safety and efficiency.
Measured: Assessed during the surgical procedure.
Rate of Perioperative Complications
This measure records the incidence and severity of complications occurring during the perioperative period. Complications will be categorized according to the Clavien-Dindo classification and summarized using the Comprehensive Complication Index, providing a quantitative assessment of overall surgical morbidity.
Measured: Assessed 7 days, 1 month, 3 months, 6 months, and 12 months postoperatively.
