About this study

Official title: Clinical Safety and Efficacy of S53P4 Bioactive Glass Putty in Spinal Fusion Surgery: Post Market Clinical Follow-up Study

A retrospective, single-tertiary centre observational study.

The study population consists mainly of patients with instrumented posterolateral spine fusion operated at the Department of Neurosurgery or at the Department of Orthopaedics and Traumatology in the Turku University Hospital. Also, patients with non-instrumented posterolateral spine fusion, interbody spine fusion, and a combination of posterolateral and interbody spine fusion are included.

The approximate number of the above-mentioned operations with BonAlive® putty is 400 - 500 between September 2013 and April 2021. In the operations, the BonAlive® putty was used either alone, together with autologous bone (AB) chips, with milled allogenous bone chips, with demineralized bone matrix (DBM), with other synthetic bone grafts, or with a combination of the above-mentioned.

Read the detailed description

In the first stage of the investigation, the clinical safety and efficacy of BonAlive® putty are assessed in a retrospective case-series, and the observations are compared to the existing literature. Thereafter, a retrospective case-controlled study will be created to compare the use of a mixture of BonAlive® putty and AB to AB alone for clinical safety and efficacy. The cases will be matched up with the controls by gender, age, smoking behavior, the number of operated levels and the site of operated levels as far as possible. The chosen surgical technique will be the most commonly used.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To demonstrate the clinical efficacy of BonAlive® (S53P4 bioactive glass) putty in spine fusion operations when used alone and together with autologous bone.

    Radiologic endpoints are based on a neuroradiologist evaluatyion possible complications (breakage and/or loosening of the instrumentation) and bony fusion on a modified Bridwell grading criteria I-IV for PLF.

    Measured: 24 months

  2. Clinical outcomes are for pain VAS:

    Visual analogue scale 1-10.

    Measured: 24 months

  3. EQ-5D cost effectiviness questionnaires.

    Values are anchored at 1 (full health) and 0 (a state as bad as being dead) as required by their use in economic evaluation.

    Measured: 24 months

  4. ODI: (Oswestry Low Back Pain Disability Questionnaire).

    ODI is validated to use in patients with low back pain.The final score/index ranges from 0-100. A score of 0-20 reflects minimal disability, 21-40 moderate disability, 41-60 severe disability, 61-80 crippled, and 81-100 bed-bound.

    Measured: 24 months

  5. 15 D questionnaire The 15D is a generic, comprehensive (15-dimensional), self-administered instrument for measuring HRQoL among adults.

    Health index on a 0-1 scale has been used successfully in several pharmacoeconomic evaluations. The maximum score is 1 (no problems on any dimension) and the minimum score is 0 (being dead).

    Measured: 24 months

Secondary outcomes (2)
  1. To demonstrate that the clinical efficacy of BonAlive® putty used together with autologous bone in spine fusion operations is not inferior to the clinical efficacy of autologous bone used alone.

    Radiologic endpoints are based on a neuroradiologist evaluation possible complications; 1. breakage and/or loosening of the instrumentation 2. bony fusion on a modified Bridwell grading criteria for PLF.

    Measured: 24 months

  2. To demonstrate that the clinical use of BonAlive® putty does not cause excess infections or other complications subsequent to spine fusion operations compared to the reported amounts in the literature without the use of BonAlive® putty.

    Odom´s scale

    1 Excellent: No symptoms related to cervicaldisease.Able to perform daily activities without limitations. 2 Good: Moderate symptoms related tocervical disease.Able to perform daily activities without significant limitations. 3 Satisfactory: Slight improvement in symptomsrelated to cervical disease.Significant limitations in daily activities. 4 Poor: No improvement in, or aggravation of,symptoms related to cervical disease.Not able to perform daily activities.

    Measured: 24 months

Questions about this trial

What is this clinical trial studying?

An observational study of Spine Fusion and Spinal Deformity, run by Bonalive Biomaterials Ltd at 1 site in Finland.

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 2 inclusion and 3 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 12 Aug 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 Finland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To demonstrate the clinical efficacy of BonAlive® (S53P4 bioactive glass) putty in spine fusion operations when used alone and together with autologous bone. (time frame: 24 months). The study lists 5 primary outcomes in all. 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?
