NCT05612139

Brief Summary

This study has been planned as part of the Orthofix Srl post-market active surveillance plan for the collection of data on both the clinical performance and the safety profile of the JTIN. The rationale of the proposed study is to update and support the pre-market clinical evaluation of the JTIN with Real World Evidence clinical data in a real-life surgical setting, in order to confirm the benefit/risk ratio of this medical device and to keep the CE mark under Medical Device Regulation (MDR) requirements. One selected site, experienced in the treatment of pediatric patients with OI, where the usage of JTIN is already part of the normal clinical practice, will participate in this study.

Outcome Measures

Primary Outcomes (1)

  • Percentage of Procedures With at Least One Serious/Not Serious Adverse Event Certainly or Possibly Related to JTIN

    The primary endpoint is measured to evaluate the clinical safety profile of JTIN within the scope of its intended purpose.

    1 year

Secondary Outcomes (3)

  • Implant Survival Rate: Percentage of Not Exchanged Nails

    1 year

  • Percentage of Procedures With Bone Union Achievement

    1 year

  • Post-treatment Fracture-free Survival Rate

    1 year

Study Arms (1)

JTIN treated patients

Pediatric patients, older than 18 months, suffering from osteogenesis imperfecta treated with JTIN telescopic nail

Device: JTIN implantation surgery

Interventions

The JTIN is a self-extending intramedullary nail (telescopic rod) designed to provide fixation of femoral and/or tibial fractures, osteotomies, malunions and non-unions. The design of the JTIN includes a female and a male component, which are anchored to the proximal cortex and distal epiphysis through screw-type fixation. These two components slide from each other, allowing for extension of the JTIN as the bone structures remodel and patient growth occurs.

Study Population

Pediatric patients older than 18 months suffering from osteogenesis imperfecta.

You may qualify if:

  • is in pediatric age (\> 18 month and \< 18 years) at the time of surgery;
  • is skeletally immature;
  • has a diagnosis for OI;
  • has a regular indication for surgical intervention with JTIN to treat femoral and/or tibial fractures, osteotomies, malunions and non-unions;
  • patient and/or legal representative is duly informed and doesn't oppose to participation.

You may not qualify if:

  • has a medical condition that is a contraindication according to the manufacturer's instruction for use;
  • has any conditions that in the Investigator's opinion may interfere with the study execution or due to which the patient should not participate for safety reasons;
  • requires the application of, or has already in-situ the application of concomitant devices that cannot be safely removed (except for permitted concomitant devices paragraph);
  • is participating in other clinical trials or has taken part in any clinical study in the last 3 months with exception of analytical trials on genetics study related to OI (i.e. studies that do not include an investigational treatment for the patient such as new drugs or other medical devices);
  • is likely to be lost to follow up, according to investigator's opinion.
