A staple instrument includes a staple holder comprising a pair of jaws, a drive shaft, a rotational handle, and a coupling to convert rotational motion of the handle into axial advancement of the shaft. A distal end of the shaft cooperates with the staple holder to cause three-point bending of a staple bridge to thereby open the legs of the staple.

Staple instrument

A Lisfranc reconstruction device includes a pair of operator grips mechanically linked to a first arm that includes a barrel and a second arm that includes a jaw whereby motion of the grips is mechanically transformed into relative translation of the barrel and the jaw for compression of a portion of a Lisfranc joint complex therebetween. The device includes a retention mechanism, such as a ratchet, to enable retention of the barrel and jaw when the desired position has been reached. The device may be provided in the form of a kit that includes a wire guide sleeve, a pilot wire, and a Lisfranc screw, in particular a cannulated Lisfranc screw that is sized to travel over the wire in a defined trajectory to facilitate proper screw placement. The device may be used for reconstruction of a traumatic injury to the Lisfranc joint complex.

Lisfranc reconstruction device, kit, and method

A surgical staple is provided having a bridge and at least a first leg and a second leg. The bridge has a first end and a second end. The surgical staple has a first extension of the bridge adjacent the first end of the bridge and extending on an opposite side of the first leg relative to the second leg and a second extension of the bridge adjacent the second end of the bridge and extending on an opposite side of the second leg relative to the first leg. The bridge may also have a waisted or reduced width mid-section.

Surgical staple

A compression device made of a superelastic material having a peripheral portion with an upper surface, a lower surface, and a central opening extending therethrough is provided. Tips of one or more resilient structures of the compression device project inward of the peripheral portion and form an opening. The one or more resilient structures are configured to exert a biasing force in a direction when deformed in an opposite direction. Also provided is a bone plate assembly comprising a captively retained compression device and a bone plate comprising one or more integrally formed resilient structures.

Compression device, bone plate, bone plate assembly, kit, and method

Apparatus and methods are described for use in securing a first bone relative to a second bone using a pair of surgical staples or, alternatively, a surgical staple and a bone screw. When a pair of staples are used, one of the legs of one of the staples may pass between the legs of the another of the staples. When a staple and a bone screw are used, the bone screw may pass between the legs of the staple. A guide tool can be used during the drilling of the holes for the legs of the staples or the legs of the staple and a bone screw. The guide tool provides guides for drilling guide holes for the staples or for the screw and staple.

Apparatus and methods for joining bones

Apparatus and methods are provided for using a plate to fuse bones together, including reducing or stabilizing a fracture or osteotomy. Legs of the plate are inserted into pre-drilled guide holes in one of the bones and one or more screws are inserted through apertures and into another of the bones to secure the plate to the bones. A plate insertion tool can be used to temporarily tension the legs prior to insertion into predrilled guide holes in a bone by bending or pivoting the legs away from the body. A tensioning tool can be used to tension the plate after the legs are inserted into the guide holes in the bone and during the insertion of one or more of the screws.

An orthopedic stabilization device is provided having a first button and a suture. The first button includes a base portion and a locking loop extending from a distal surface thereof, and a locking member slidably receiving the locking loop. At least a portion of the suture extends through the locking loop superior the locking member in the axial direction and at least a portion of the suture extends through the locking loop inferior the locking member in the axial direction such that a portion of said suture is frictionally retainable between said locking member and said locking loop when the suture is tensioned. The device may include a second button with the suture disposed between the first and second buttons such that the suture may be held in tension therebetween.

When a pair of staples are used, one of the legs of one of the staples may pass between the legs of the another of the staples. When a staple and a bone screw are used, the bone screw may pass between the legs of the staple. A guide tool can be used during the drilling of the holes for the legs of the staples or the legs of the staple and a bone screw. The guide tool provides guides for drilling guide holes for the staples or for the screw and staple. The guides can be fixed relative to each other during drilling of the guide holes.

A compression device made of a superelastic material having a peripheral portion with an upper surface, a lower surface, and a central opening extending therethrough is provided. One or more resilient teeth project inward of the peripheral portion into the central opening and are configured to exert a biasing force in an axial direction when deformed in a direction opposite the axial direction.

Deformable medical compression device

A bone plate system comprises a bone screw and a bone plate having at least two screw-receiving hole structures, at least one of the hole structures comprising an eccentric portion adjacent a first seating area for biasing bone in an inferior fusion area into dynamic compression as the screw is advanced, and a cowl portion that at least partially defines a second seating area and being positioned to enable cross-screw compression of an inferior fusion area. The screw is seatable in either the first or second seating area at the option of a surgeon. A surgical method generally comprises inserting a bone screw into the compression plate and compressing bone in an inferior fusion area by either dynamic or cross-screw compression.
