Methods are described for conducting minimally invasive medical interventions utilizing instruments and assemblies thereof to stabilize and/or fixate a dysfunctional sacroiliac (SI) joint. The methods include the initial steps of providing a drill guide assembly adapted to create a pilot opening in the dysfunctional SI joint, a prosthesis configured to be inserted into the pilot opening created by the drill guide assembly and a prosthesis deployment assembly adapted to engage and advance the prosthesis into the pilot opening in the dysfunctional SI joint. The drill guide assembly includes a drill guide having a prosthesis access opening therethrough; the opening having a configuration that corresponds to the shape of the prosthesis. In some aspects of the invention, the methods thus include the step of advancing the prosthesis through the drill guide and then into the pilot opening in the dysfunctional SI joint with the prosthesis deployment assembly; the initial advancement of the prosthesis through the drill guide providing consistent, optimal placement of the prosthesis in the dysfunctional SI joint.

The present invention relates generally to implants used in medical procedures such as bone fixation or fusion. More specifically, this application relates to fenestrated implants used in bone fixation or fusion.

Configurations are described for conducting minimally invasive medical interventions utilizing elongate instruments and assemblies thereof to stabilize and/or fixate a sacro-iliac joint. In one embodiment, a tool assembly may be advanced from a posterior approach into the SI junction and configured to create a defect defined at least in part by portions of both the sacrum and the ilium, the defect having a three dimensional shape defined in part by at least one noncircular cross sectional shape in a plane substantially perpendicular to the longitudinal axis of the tool assembly. After a defect is created, the tool assembly may be retracted and a prosthesis deployed into the defect.

The present invention relates generally to implants used in medical procedures such as bone fixation or fusion. More specifically, this application relates to fenestrated implants used in bone fixation or fusion.

A system for decorticating at least one bone surface includes an elongated soft tissue protector, an elongated drive shaft and a cutter. The elongated soft tissue protector has a bore extending therethrough. The bore has a non-circular lateral cross-section, a maximum lateral extent and a minimum lateral extent. The cutter may be located on or near a distal end of the drive shaft. The cutter has a non-circular lateral cross-section, a maximum lateral extent and a minimum lateral extent. The maximum lateral extent of the cutter is greater than the minimum lateral extent of the bore but is no greater than the maximum lateral extent of the bore. The bore of the soft tissue protector is configured to slidably receive the cutter therethrough. Other systems and methods for decorticating at least one bone surface are also provided.

A decompression device and method for removing marrow and other fluid from an intramedullary canal. The decompression device includes a cannula having a channel that allows fatty marrow to pass therethrough. A first port extends from the device and is in operable connection to a vacuum source that creates suction for removing fluid from the intramedullary canal. In some embodiments, one or more fenestrations are disposed along the second end of the cannula to expedite the removal of the fluid. In operation, the cannula is inserted into the intramedullary canal of a femur. Once fatty marrow is removed from the intramedullary canal, the cannula is removed and a reaming device is inserted into the femur. In this way, the fatty marrow is removed prior to the reaming procedure in order to prevent these fluids from traveling to the lungs causing blockage that leads to severe cardiorespiratory and vascular dysfunction.

The Modified anatomical direct lateral approach (Vitosha approach), a novel approach in hip arthroplasty, preserving the iliofemoral ligament and restoring the joint capsule, providing higher initial joint stability and easier rehabilitation without the need for post-operative patients' dislocation precautions is provided. The fascial incision curves along the posterior aspect of the greater trochanter and ends at its lower border, preventing a split of vastus lateralis muscle. The anterolateral periosteal layer which conjoins the gluteus medius and vastus lateralis muscles is sharply elevated from the greater trochanter. Gluteus medius muscle and the underlying gluteus minimus are split along its fibers and retracted anteriorly. A vertical capsular incision is made anterior to the femoral shaft, starting from the basicervical line and extending proximally along the longitudinal body axis, with the iliofemoral ligament fibers remained intact.

A medical device for implantation in a hip joint of a human patient is provided. The natural hip joint having a ball shaped caput femur as the proximal part of the femoral bone with a convex hip joint surface towards the centre of the hip joint and a bowl shaped acetabulum as part of the pelvic bone with a concave hip joint surface towards the centre of the hip joint. The caput femur has a centrally placed longitudinal extension, extending through the center of the caput and collum femur, aligned with the collum femur, defined as the caput and collum femur center axis. The medical device comprising; an artificial acetabulum, comprising a concave surface towards the centre of the hip joint. The artificial concave acetabulum is adapted to, when implanted, be fixated to the femoral bone of the human patient, and be in movable connection with an artificial caput femur fixated to the pelvic bone of the patient.

A method for fixating an artificial convex caput femur surface to the pelvic bone of a patient, the method comprising the steps of: exposing the acetabulum surface, creating a hole or recess in the pelvic bone from the acetabulum side of the pelvic bone, providing the artificial convex caput femur, comprising an elongated member to the hip joint, inserting said elongated member in said hole, and performing an action on the acetabulum side of the pelvic bone such that the elongated member is structurally changed on the abdominal side of the pelvic bone or inside the pelvic bone.

An articulating rotary cutting tool configured to articulate a distal cutting tip upon a trigger being operated. The trigger can be locked into various articulating positions. The velocity of rotation of a cutting bit is substantially constant in both articulating and non-articulating positions. An articulation joint is one of a hex ball joint or a flexible spring joint. A button is included to release a locking pressure holding the trigger in a locked position. The trigger may employ articulating sliding surfaces that provide constraint to a flexed head in both directions of articulation.
