Interpretation of regulatory factors for 3D printing at hospitals and medical centers, or at the point of care.

3D printing is revolutionizing the medical device landscape through its ability to rapidly create patient-specific anatomic models, surgical instruments, and implants. Recent advances in 3D printing technology have allowed for the creation of point-of-care (PoC) 3D printing centers. These PoC centers blur the line between healthcare provider, medical center, and device manufacturer, creating regulatory ambiguity.

Partial Hand Transplant: Lessons Learned From Cadaveric Dissection Studies.

As the field of vascularized composite allotransplantation continues to expand, new upper extremity transplant candidates are being considered. We recently evaluated a bilateral amputee who had a mid-forearm amputation and a contralateral metacarpal hand amputation. In the latter limb, a "partial" hand transplant that preserved the majority of the patient's existing hand, including a partially severed thumb with intact thenar muscle function, was proposed.
