About this study

There is a high probability of mechanical complications in patients with degenerative lumbar scoliosis after long segment fixation and fusion, and there are few studies on distal borderline kyphosis deformity/failure. This study was designed to retrospectively analyze the patients with degenerative lumbar scoliosis (DLS) who underwent posterior selective decompression and long segment fixation and fusion surgery in the lumbar spine department of our hospital from April 2009 to May 2016. Patients' basic data, surgical data and preoperative, immediate postoperative and follow-up imaging data were collected to study the incidence of distal mechanical complications, risk factors and their relationship with clinical symptom scores in DLS patients undergoing posterior selective decompression and long segment fixation and fusion. It has guiding significance for clinical operation decision making.

Questions about this trial

What is this clinical trial studying?

An observational study of Degenerative Scoliosis, run by Peking University Third Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 13 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Imaging and Endoplant-related Mechanical Complications (time frame: 2019.1.1-2025.12.31). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jul 2021.
