Implant assembly for low profile spinopelvic fixation and sacroiliac joint fusion
An orthopedic anchoring system for attaching a spinal stabilization system and concomitantly fusing a sacroiliac joint is disclosed that includes a delivery tool and an implant assembly for insertion into a joint space of a sacroiliac joint. The implant assembly may be secured using anchors inserted through bores within the implant body and into the underlying sacrum and/or ilium. The implant body may also include an attachment fitting reversibly attached to a guide to provide attachment fittings for elements of the spinal stabilization system. The implant assembly may be releasably coupled to an implant arm of the delivery tool such that the implant arm is substantially aligned with the insertion element of the implant assembly. An anchor arm used to insert the anchor may be coupled to the implant arm in a fixed and nonadjustable arrangement such that the anchor is generally aligned with a bore within the implant assembly.
Methods of fusing a sacroiliac joint with an additively manufactured sacroiliac joint implant
A system for fixating a dysfunctional sacroiliac joint for SI joint fusion, the system including a sacroiliac joint implant and a delivery tool configured for approaching a sacroiliac joint. The system may include an implant having a porous 3D matrix structure and may be manufactured by laser or electron beam additive manufacturing. The delivery tool may include a radiolucent material. The SI fusion system may further include custom sacroiliac joint implants, anchors, alignment tools or targeting arms manufactured for a particular patient. Pre-surgical imaging studies, including 3D rendering, and their interpretation may assist in planning desired trajectories, anchor dimensions and implant dimensions and may provide details specific to the manufacture of particular sacroiliac joint tools or implants and their implantation into the sacroiliac joint. The system may be configured for use with surgical robots and may include an integrated nerve monitoring and stimulation system.
SPINAL IMPLANT SYSTEM AND METHOD
A method for treating a spine is provided. The method includes the steps of: disposing an interbody implant adjacent a posterior portion of an intervertebral disc space; connecting a surgical instrument with at least one fixation element fastened with tissue adjacent the posterior portion; and manipulating the surgical instrument such that tissue adjacent the posterior portion engages the interbody implant and one or more vertebra rotate about the interbody implant. Spinal implants; surgical instruments and systems are disclosed.
OSTEOLYSIS-RESISTANT CEMENTLESS JOINT IMPLANT WITH IMPROVED STABILITY AND SEATING FUNCTION
An improvised anthroplastic prosthetic implant having, in some embodiments, secondary screws with threaded shafts for forming pilot holes into the resected cancellous bone surface, such as the tibia, and primary screws with tapered heads for replacing the secondary screws and forming a Morse friction fit with the implant and seating the implant in close apposition to, and at less than 150 um in, resected bone thereby facilitating implant stability, wherein the heads of the primary screws are recessed into a counterbore in the baseplate to improve axial postoperative stability of the implant.
HIP JOINT INSTRUMENT AND METHOD
The present invention relates to a method of treating a hip joint of a human patient, the hip joint comprising an acetabulum, the acetabulum being a part of the pelvic bone, and a caput femur, the caput femur being the proximal part of the femoral bone, said method comprising the steps of: cutting the skin of the human patient, dissecting an area of the pelvic bone on the opposite side from the acetabulum, creating a hole in said dissected area, said hole passing through the pelvic bone and into the hip joint of the human patient, and performing an action in the hip joint, through said hole in the pelvic bone.
Systems for and methods of preparing and fusing a sacroiliac joint
A system for performing a fusion procedure on a sacroiliac joint defined between a sacrum and an ilium. The system may include a working cannula including a proximal end, a distal end, a tubular body extending between the proximal and distal ends, a cannula passageway defined within the tubular body and having a cannula axis extending there through, a pair of prongs coupled to the tubular body and extending distally there from, an anchor arm engagement structure coupled to the tubular body, and a pin guide coupled to the tubular body and defining a pin passageway having a guidance axis there through that is generally parallel with the cannula axis.
Sacroiliac joint implant system
A method of treating a sacroiliac joint at a sacroiliac joint region having a sacrum, an ilium and a sacroiliac joint space therebetween, the method comprising: a) delivering a joint implant into the sacroiliac joint region, the joint implant comprising a body including a length extending between a proximal end and a distal end, an external surface extending the length, and a fixation member receiving channel extending the length and disposed in the external surface; and b) delivering a fixation member into the fixation member receiving channel thereby forming a joint implant assembly, the fixation member slidingly and matingly engaging the fixation member receiving channel in a grooved arrangement, wherein, when the fixation member is received into the fixation member receiving channel, the fixation member extends outward from the external surface of the joint implant and extends a portion of the length.
Spinopelvic fixation technology
Systems and methods for treating musculo skeletal disorders of the spinopelvic anatomy including treating spinal deformities by spinopelvic fixation including fusion of the sacroiliac joint at the base of long spinal fusion construct cases. The system may include implants designed to be used as an adjunct to long spinal fusions to further the immobilization and stabilization of the sacroiliac joint. The implants may be designed to augment an S2AI screw and an S1 screw in order to improve durability of the foundation of the spinal construct. The implants may have a triangular cross section.
Punch, Implant and Associated Method
A method of performing joint arthroplasty includes accessing a surface on a bone and supporting a stop with the accessed surface. The method includes positioning an instrument at least partially within the stop, the instrument having a body and a punch, the punch including a portion thereof having a shape similar to a shape of a stem of an implant, and rotating the stop with respect to the accessed surface based upon an indicia on one of the body and the stop so as to position the punch rotationally with respect to the accessed surface at a first orientation. The method further includes moving the body axially with respect to the stop to form a cavity in the bone with the punch at the first rotational orientation, the formed cavity having a shape similar to the stem of the implant, and implanting the stem of the implant into the cavity.
Kit for building a cage for spondylodesis and method therefor
A modular kit and/or method buildings a cage for spondylodesis, wherein the kit and/or method comprises at least two plates, wherein the plates comprise a biocompatible material and each comprise a planar structure and a plurality of pins projecting from the planar structure of the plates, wherein the pins each comprise at least one latching element, wherein the pins are elastically deformable and are arranged sufficiently close to each other on the planar structure such that pressing planar structures studded with pins of several plates onto each other causes the latching elements of different plates to snap into each other, wherein at least two of the at least two plates comprise a recess with a diameter of at least 5 mm.
