What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial tests whether robot-assisted surgery can align broken thigh bones (femur fractures) more precisely than traditional surgeon-performed methods. Adults with a closed femur fracture are randomly assigned to receive either robot-assisted or conventional reduction, followed by standard internal fixation. The study measures how well the bone fragments align, surgical time, blood loss, healing, and functional recovery over a year. The goal is to see if robotic assistance improves outcomes and reduces trauma.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Robot-assisted closed reduction procedure
What this could lead to
If successful, this could make femur fracture surgery more precise, potentially improving bone alignment and speeding up recovery.
What could go wrong
The trial is relatively small and early, so results may not apply to all patients. Robot-assisted surgery may not always outperform traditional methods and could carry technical risks.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 80 people

The number the study aims to enrol. It can still change while the study runs.

Started

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria： * Age 18 to 80 years, inclusive. * Unilateral, acute, closed femoral shaft fracture. * AO/OTA classification 32-A, 32-B, or 32-C femoral shaft fracture. * Time from injury to surgery no more than 21 days. * Ability to walk independently before injury, with or without assistive devices. * Ability to provide written informed consent. Exclusion Criteria： * Open fracture. * Multiple severe trauma requiring immediate priority management. * Asymmetry of the lower limbs. * History of ipsilateral femoral shaft malunion. * History of ipsilateral femoral deformity that significantly affects assessment of - limb rotation or length. * Ipsilateral fracture at another site. * Pathological fracture caused by tumor, metabolic bone disease, or other underlying bone pathology. * Complex hardware from previous ipsilateral surgery. * History of ipsilateral surgery that significantly affects clinical or radiographic evaluation. * Active infection. * Severe underlying medical condition that makes the patient unable to tolerate surgery. * Cognitive impairment that prevents study participation or follow-up. * Poor compliance with study procedures or follow-up. * Pregnancy or lactation. * Judged by the investigators to be unsuitable for enrollment. * Unable to complete the planned follow-up period. * Refusal to undergo randomization. * Refusal to participate in the clinical study.
