Description
Alexander Kopp and co-authors follow dissolving magnesium bone screws in mini pigs for eighteen months in a 2026 study. Magnesium gear can hold bone while it heals and then melt away, which spares a second surgery, but fast melt can break hold and puff gas pockets. A plasma coat meant to slow the melt was tested against bare gear of the same alloy in leg and arm bones.
Coated and bare screws and plates sat in non broken bones and were checked by fine scans and tissue cuts after removal. Bare gear had melted away in full, while coated gear kept part of its frame, which shows the coat worked. Coated gear also sat in richer mature bone and caused no late harm. The coat may suit load bearing fixings.
