Study summary

This research project compares the clinical performance of the cortical bone trajectory CBT insertion technique with the current clinical Gold standard, the Pedicle screw insertion technique. Both techniques are performed by aid of MySpine patient-specific guide systems.

Read the detailed description

Adult subjects, among those whose clinical condition makes them eligible for a spinal stabilization and meeting the inclusion/exclusion criteria, will be invited to participate to the research project and ask to sign a consent in order to further use of personal and clinical data collected during standard practice visit.

The primary objective of the research project is to compare clinical outcomes, in terms of assessing the main outcomes of importance to patients with back problems (pain, function, symptom-specific well-being, quality of life, disability), of spine surgery with cortical bone trajectory screw placement technique respect the traditional pedicle screw placement technique. Preoperative data and collected during visit as per standard routine at 6 weeks, 3, 6 and 12 months postop will be recoreded and assessed for the purpose of this research project.

Study population

Patients listed for lumbar intervertebral body fusion meeting all inclusion/exclusion criteria, will be proposed to take part to the current comparative research project during their pre-operative visit (consecutive ongoing recruitment through project leader in daily clinical practice). They will be provided with an information letter and, in case of acceptance to participate to the research project, asked to sign a consent form in order to further use of personal and clinical data collected during standard practice visit. The patient will be assigned to the research project group according to two consecutive series (First serie: MySpine MC and second serie: MySpine STD).

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. patients affected by degenerative disc disease, osteochondrosis and grade I spondylolisthesis needing a one/two level surgical treatment with posterior approach and screw fixation
  2. those who need a surgical procedure of lumbar spine stabilization from level L1 to level L5.
  3. patients who are willing and able to provide written for participation in the study. Written informed consent must be obtained prior to the patient's surgery
  4. Healthy patients or patients with mild or severe systemic disease identified as patients with 1, 2 or 3.
  5. Patients with ≤ 35 kg/m2
  6. non responsive or insufficient response to conservative treatment.

Exclusion criteria

Exclusion Criteria:

  1. Patients presenting as defined by Medacta instruction for use
  2. Patients affected by lytic spondylolisthesis and degenerative spondylolisthesis with grade≥2 will be excluded
  3. Patients \<18 years
  4. Patients who are pregnant or intend to become pregnant during the study
  5. Known substance or alcohol abuse
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

ASA physical status

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

What researchers measure

Primary outcomes

  1. Spine surgical patient outcome changing in the time respect the preoperative

    Change in Core Outcome Measures Index (COMI) for the assessment of people affected by degenerative lumbar disease in daily practice

    Time frame: baseline, 6 weeks, 3 months, 6 months, 12 months

Secondary outcomes

  1. Spine Disability index

    questionnaire for assessing functional status and quality-of-life impairment in patients with low back pain or spinal cord disease and injury in research and clinical settings. he index enquires about functional limitations in various activities of daily living with the index score ranging from 1 (best) to 100 (worst). Among others, pain intensity, personal hygiene, walking, sleeping, social life, sexual life (optional) and travel are assessed by the patient. Each section has six possible responses, which are scored from 0 to 5.

    Time frame: baseline, 6 weeks, 3 months, 6 months, 12 months

  2. Pain perception

    A visual analog scale (from no pain "0" to severe pain "10") to evaluate low back pain

    Time frame: baseline, 6 weeks, 3 months, 6 months, 12 months

  3. Bone fusion

    A postoperative CT scan will be performed to asses bone fusion at index level defining the presence of bridging bone.

    Time frame: baseline, 12 months

  4. Incidence of adverse event Device-related

    Colleciton of all adverse event for all study duration

    Time frame: baseline, 6 weeks, 3 months, 6 months, 12 months
