Si-Bone, Inc.
A maker of titanium and bone implants for the sacroiliac (SI) joint, where the spine meets the pelvis. Its iFuse line of triangular, 3D-printed titanium implants is used in minimally invasive surgery to fuse that joint and ease lower-back and pelvic pain. Founded in 2008 by orthopedic surgeon Dr. Mark Reiley, who also invented kyphoplasty, the company's name simply nods to its focus: "SI" stands for sacroiliac.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last year: -530.3K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
