An observational study in Fracture, Lengthening; Leg and Orthopedic Disorder, sponsored by University of British Columbia. Recruiting at 1 site in Canada. Open to participants aged 0 Years to 25 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-11-09.
Sponsored by University of British Columbia · Observational
Implant devices are important tools - their use is essential across a number of orthopaedic indications, including hip conditions, trauma and limb deformity.
Given the vital role fixation devices play in maintaining alignment, promoting healthy bone healing and preventing joint degeneration, it is essential to understand the expected lifetime outcomes of these implants, and evaluate their safety and efficacy.
Prospective implant efficacy and safety registries are needed to support this endeavour, especially considering new regulatory requirements from the European Union Medical Devices Regulation (EU MDR) in relation to post-market clinical follow-up (PMCF).
STUDY PROCEDURES Screening Patients will be screened against basic inclusion/exclusion criteria to see if patients may be appropriate for study participation according to any standard of care assessments available, and where appropriate with the site's REB/IRB screening procedures and local regulatory requirements. If a patient is deemed eligible, data outlined throughout this protocol will be collected, de-identified and entered into a Research Electronic Database Capture (REDCap) system managed at BCCH.
Enrollment Patients will be assigned a sequential, unique study number (subject ID) and de-identified data will be entered in the study database. The center number is designated by the BCCH team for each individual investigational site. The patient number will be in sequential order by the patient screening date starting with 001. Once a patient has been assigned a subject ID, the number will not be reused.
Pre-Operative Procedures Once a patient is identified as eligible for an Implant Safety and Efficacy device report, it will be determined whether that patient is already enrolled in one of the existing condition-specific registries. Should participants be enrolled in a condition-specific registry, demographic data, medical history, preoperative clinical data, including any pre-existing infections at or near the operative site, and data on pre-operative radiographs for the relevant underlying diagnosis will have already been prospectively collected under registry procedures. If a patient has not been previously enrolled in a condition-specific registry, the patient will be offered enrollment in both the condition registry and for the purposes of the Implant Safety and Efficacy device report. Demographic data, medical history, preoperative clinical data and data on pre-operative radiographs for the relevant underlying diagnosis will then be collected retrospectively from the medical record.
Required Data Collection:
Operative details in the source documentation will be collected that provide specific information from the subject's surgery such as surgical approach, complications, and unique device identification (UDI) numbers for the implanted device.
The following data will be collected and entered into the registry:
Follow-up Procedures
Data collected during routine standard of care follow-up visits will be collected as part of this study. The following data will be collected:
The condition-specific registries are designed to capture every visit that occurs, whether scheduled or unscheduled. An unscheduled visit may occur when an adverse event occurs, or when a patient returns outside of the planned interval window. If an unscheduled visit occurs, the following assessments are to be done:
723 studies on the registry are indexed under Fractures, Bone; 114 are open to participants now.
This study's planned enrollment of 4,000 is above the median of 130 across 239 observational studies indexed under Fractures, Bone.

Exclusion Criteria:
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.
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.

Pediatric patients indicated for the device-specific indication, per physician discretion and as indicated in the device IFU.
Device: Pediatric orthopaedic implant
Patient receives a pediatric orthopaedic implant as a part of standard clinical care.
Device related adverse events
Determine the frequency and severity of device-related adverse events at device-specific end points. All adverse events will be recorded and followed during the study. The frequency and severity of device related adverse events will be analyzed to ensure the device risk profile has not changed.
Time frame: 2 years post implant insertion
Implant survival
Determine the implant survival rate at post-operative end-point: (lack of revision)
Time frame: 2 years post implant insertion
Implant efficacy
Efficacy will be assessed by post-operative clinical and radiographic evaluations at each follow-up end-point to assess bone fixation and/or deformity correction.
Time frame: 2 years post implant insertion
Numeric pain rating scale (NPRS)
The numeric pain rating scale (NPRS) is a subjective, 11-point numerical scale in which respondents self-report their pain on a scale of 0 (no pain at all) to 10 (worst pain imaginable).
Time frame: 2 years post implant insertion
LIMB-Q Kids
LIMB-Q Kids is a new patient reported outcome measure (PROM) for children with lower limb deformities.
Time frame: 2 years post implant insertion
PROMIS
The Patient Reported Outcomes Measurement Information System (PROMIS) measures are self-reported and parent-reported. It includes over 300 measures of global, physical, mental, and social health for adults and children in the general population and those living with a chronic condition. Specifically, the PROMIS Global Health will be administered to all patients while the PROMIS Physical Function - Mobility short form will be administered to those with an implant used in a lower extremity and the PROMIS Physical Function - Upper Extremity short form will be administered to those with an implant used in an upper extremity.
Time frame: 2 years post implant insertion

Started Jan 2022 (actual). Primary completion is estimated for Dec 2028, 83 months after the start.
Of 66 non-industry observational studies under Fractures, Bone, half reached primary completion within 43 months of starting (the median), counting those still running; a quarter within 20 and three quarters within 88. This study's planned 83 months is above that.
Counting every sponsor, half of 86 studies reached it within 46 months; a quarter within 20 and three quarters within 124.
