Abstract
Guidewires for facilitating the placement of implants and instruments during orthopedic surgery are disclosed. The guidewires are constructed and arranged to minimize and prevent undesired migration and/or rotation of the guidewire at a surgical site. Associated methods of performing surgery, e.g. a Sacroiliac (SI) joint fusion procedure, using the guidewire are also disclosed.
Claims27
A method of performing orthopedic surgery using a guidewire, the method comprising the steps of:
- forming a cannulation or through hole in one or more targeted bones at a surgical site;
- positioning a guidewire down into the cannulation or through hole, the guidewire having:
- a distal tip, a proximal portion, and an expansion segment along a length of the guidewire;
- the expansion segment defining a plurality of flanges being deformable from a non-expanded form to an expanded form upon advancement of the guidewire into the surgical site to resist forward and/or rotational motion of the guidewire, the non-expanded form of the expansion segment allowing for a diameter or cross-sectional area thereof to be equal to or less than a diameter or cross-section of the proximal portion of the guidewire when contained within a surgical tool or sheath, and the expanded form of the expansion segment allowing for expansion of the flanges in an outward direction to increase the cross-sectional area of the expansion segment relative to the proximal portion to resist forward advancement of the guidewire into the surgical site,
- wherein any additional advancement of the guidewire promotes further deformation of the flanges in the outward direction causing further resistance to forward and/or rotational motion;
- delivering an implant to the target bone(s) using the guidewire;
- and
- removing the guidewire.
A guidewire for facilitating orthopedic surgical procedures, the guidewire comprising:
- a distal tip, a proximal portion, and an expansion segment along a length of the guidewire;
- the expansion segment defining a plurality of flanges being deformable from a non-expanded form to an expanded form upon advancement of the guidewire into a surgical site to resist forward and/or rotational motion of the guidewire, the non-expanded form of the expansion segment allowing for a diameter or cross-sectional area thereof to be equal to or less than a diameter or cross-section of the proximal portion of the guidewire when contained within a surgical tool or sheath, and the expanded form of the expansion segment allowing for expansion of the flanges in an outward direction to increase the cross-sectional area of the expansion segment relative to the proximal portion to resist forward advancement of the guidewire into the surgical site,
- wherein any additional advancement of the guidewire promotes further deformation of the flanges in the outward direction causing further resistance to forward and/or rotational motion.
An orthopedic surgical kit comprising the guidewire of any of the preceding claims.
