1. A bone anchoring assembly comprising:
a bone anchor comprising:
a proximal end;
a distal end;
an outer profile suitable for defining a firm and stable coupling with a bone tissue;
a seat open on the proximal end, the seat comprising:
a threaded portion comprising a proximal end and a distal end, wherein the proximal end of the threaded portion is provided in proximity to the proximal end of the bone anchor; and
an insert configured to be received within and couple with the seat of the bone anchor, the insert comprising:
a proximal end;
a distal end;
a threaded portion comprising a proximal end and a distal end, wherein the threaded portion of the insert is configured to couple with the threaded portion of the bone anchor; and
wherein the insert is axially retained within the seat and is free to rotate about an axis of the insert,
wherein when the bone anchoring assembly is in an assembled configuration, the proximal end of the threaded portion of the insert is in an immediately distal position with respect to the distal end of the threaded portion of the seat such that the threaded portions of the insert and seat threadingly disengage when in the assembled configuration,
wherein the proximal end of the insert defines an eyelet, and wherein when the bone anchoring assembly is in the assembled configuration, the eyelet is disposed within the threaded portion of the bone anchor.
