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 Results may not be published yet.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

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.

Summary

This study looks at how much pollution and waste come from two ways of treating certain hand fractures: surgery or just letting the bone heal naturally with a splint or tape. Researchers will track 30 adults for a year, measuring things like carbon emissions and trash. The goal is to see which approach is better for the environment, without judging which is better for healing.

What this could mean

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

What this could lead to
If successful, this study could help guide more eco-friendly choices in hand fracture care without harming patient outcomes.
What could go wrong
This is a small observational study with only 30 participants, so results may not apply broadly. It measures environmental impact, not treatment effectiveness.

This is an AI summary of the original study and may miss details. Read our disclaimer.

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

Inclusion Criteria for the CARBO trial: Age ≥18 years. Access to a valid e-mail. Injury within 10 days prior to inclusion. Normal bilateral hand function prior to injury. Ability and willingness to provide written informed consent Single, displaced spiral or oblique diaphyseal fracture of the second to fifth metacarpals with definition of diaphysis as described by AO 2018 (AO/OTA as 77.2-5.2A) (Meinberg et al., 2018). Fracture line length at least twice the diameter of the bone at the level of the fracture. Fractures with at least 2 mm of radiological displacement and/or malrotation of injured finger compared to uninjured side regardless of fracture displacement. Exclusion Criteria: The patient is not expected to have difficulty adhering to the study protocol (e.g., due to insufficient language proficiency, dementia, substance abuse, or other reasons). The patient does not have an open fracture (Gustilo-Anderson grade \> I) or a pathological fracture. The patient does not have an ipsilateral fracture of the upper extremity, polytrauma, or generalized joint dysfunction (e.g., rheumatoid arthritis).
