Starting Your Research: An Orientation Framework for Limb Lengthening

Start With the Decision, Not the Device Brand

Define the question first: indication, candidate evaluation, segment, amount, method, outcomes, risk, rehabilitation, remote care, or cost. A source is useful only when its population, procedure, date, and outcome match the question closely enough.

Use the Right Source for the Claim

• Regulator database and current manufacturer instructions for indications, limits, recalls, and required removal.
• Primary studies for what occurred in a defined cohort, with design, denominator, and follow-up visible.
• Systematic reviews for the shape and gaps of the evidence, while checking heterogeneity and included eras.
• Professional or public-health guidance for broader clinical, travel, and safety recommendations.
• Institutional patient pages for that center's workflow, not universal rules.
• Provider pages and questionnaires for provider-stated facts that still require date, scope, and verification status.
• Patient experience for questions and lived context, not incidence, candidacy, or medication instructions.

Build a Claim Log

• Exact claim in your own words, source, URL or identifier, publication and access date.
• Population, indication, segment, device, method, sample size, denominator, and follow-up.
• Whether the result is crude or adjusted, absolute or relative, and the confidence interval.
• Funding, conflicts, missing follow-up, and whether the source predates a device recall or redesign.
• What the source does not establish and what remains unresolved.

When Sources Conflict

Check whether they studied different patients, devices, definitions, countries, eras, or endpoints. A provider protocol can differ from a study without either being fraudulent, but the provider should explain the rationale and evidence. Current regulator information overrides an older availability or recall statement.

Do Not Copy a Number Without Its Frame

A length, complication rate, healing index, satisfaction percentage, or return date must retain its denominator, population, method, timepoint, and uncertainty. Published averages are descriptions, not personalized targets.

Turn Research Into Consultation Questions

• Which finding in my history, examination, or imaging changes the plan?
• What exact device and current source document governs its use?
• What are your comparable outcomes, denominator, definitions, and missing follow-up?
• What are the stop rules, emergency pathway, remote-care limits, and revision responsibility?
• Which uncertainty remains after consultation, and would an independent opinion change the decision?

Date-Sensitive Information Must Be Rechecked

Device status, recalls, provider credentials, facility affiliation, prices, insurance, and travel rules can change. Record the date and verify again near consent and surgery. The FDA currently states that stainless-steel Precice devices including STRYDE remain recalled; PRECICE MAX also has an open Class II recall as of July 12, 2026. ^[1][2]
