Influence of Laminoplasty and Internal Fixation on Vertebral Stability After Laminectomy

April 18, 2016 updated by: Yuntao Lu, Southern Medical University, China

Influence of Laminoplasty and Internal Fixation on Vertebral Stability After Cervical, Thoracic and Lumbar Laminectomy for Tumor Resection

The lesion located inside the spinal canal caused big trouble for clinical treatment. Traditional laminectomy will destroy the biomechanics and influent the vertebral stability, which might cause kyphosis or other deformity. So in some centers, neurosurgeries praised laminoplasty to make the intactness of posterior column. They thought the laminoplasty can maintain the vertebral stability, and meanwhile the range of motion won't change so much. However, some other scholars thought laminoplasty had no helps for stability because of the pseudarthrosis. They preferred screw and stick system for internal fixation. And we did meet several patients after laminectomy suffered with spinal deformity. So we thought it is necessary for investigating the benefit of patients from laminoplasty and internal fixation.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

After laminectomy for removal of the cervical, thoracic and lumbar lesions, the recruited cases were randomly divided into two groups.

  1. The cases in group of laminoplasty, the lamina and spinous process was replanted to maintain the anatomical intactness of spinal canal.
  2. On the other hand, the cases in internal fixation group, the pedicle screws were implanted, and tickets were used to complete the internal fixation.

During 3 years follow up, the vertebral deformity and the range of motion were investigated and evaluated. And in the meantime, the patient's age will also be analyzed to detect it's influence for the prognosis.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Surgical perfomance (Laminoplasty)
After the lesions inside the spinal canal were surgical removed by laminectomy, the lamina and spinous process were replanted with titanium plates and screws.
Procedure: Surgical performance
Two different surgical performances
Surgical perfomance (Internal fixation)
After the lesions inside the spinal canal were surgical removed by laminectomy, the pedicle screws (Thoracic and lumbar vertebra) or lateral mass (Cervical vertebra) and sticks were used for internal fixation.
Procedure: Surgical performance
Two different surgical performances

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Vertebral deformity
Time Frame: 3 years
3 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
