Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 18 who have recently undergone decompressive hemicraniectomy.

Probably not a fit

Patients who have undergone bilateral decompressive hemicraniectomy or have certain pre-existing conditions may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates whether an external cranial prosthesis can prevent Sunken Flap Syndrome in patients who have undergone decompressive hemicraniectomy. The study aims to determine if this intervention can also reduce healthcare costs and improve recovery outcomes for patients with traumatic brain injuries, brain bleeds, or large strokes. Participants will be monitored for changes in brain function and overall health following the placement of the prosthetic device. The trial is conducted at Johns Hopkins Hospital and Johns Hopkins Bayview Medical Center.

Why it matters

Potential benefit: If successful, this approach could significantly improve recovery and quality of life for patients after craniectomy.

How similar studies have gone: While the specific use of an external cranial prosthesis is novel, similar approaches in managing post-operative complications have shown promise in other studies.
