Lateral access alignment guide and rigid arm
In one embodiment, a surgical rigid arm (100, 150, 200, 900) includes a first portion (102, 152, 202, 902), a second portion (103, 153, 203, 903) and a central portion (105, 154, 205, 906), where the central portion is extends between the first and second portions. A first end of the first portion and a second end of the second portion are each attached to a peripheral side (14) of a surgical bed (10, 30) such that the first portion and the second portion extend from the surgical bed in a first direction. The central portion extends substantially horizontally and is positioned over the surgical bed, the central portion being connected to the surgical instrument such that a load from the surgical instrument is distributed across the central portion to the first portion and second portion to provide rigid support for the surgical instrument.
Minimally invasive hip arthroplasty techniques and apparatus
A minimally invasive hip arthroplasty technique involves intramedullary insertion of an elongate femoral broach into a femur. The broach has a superior lateromedial transverse bore. A reaming rod is then located through the transverse bore and the neck of the femur. A cutting head is coupled to a distal end of the reaming rod via an incision. An orthogonal drive arm of an arthroplasty jig may also be inserted behind the cutting head to press the cutting head to ream the acetabulum while the reaming rod rotates the cutting head.
Total ankle external alignment footplate
A footplate assembly for ankle includes a footplate base; a slider arm that is rotatably coupled to the footplate base, the slider arm being configured to be couplable to external ankle instrumentation; a locking fastener configured to lock the slider arm in a chosen orientation relative to the footplate base; and a knob coupled to the footplate base having a scale to display the angle of the slider arm relative to the footplate base.
CHEVRON OSTEOTOMY TOOLS AND METHODS
A targeting guide is disclosed includes a handle extending substantially along a longitudinal axis. The longitudinal handle defines one or more burr holes extending from a first side of the handle to a second side of the handle. A head is coupled to a distal end of the longitudinal handle. The head defines a plurality of guide holes sized and configured to receive a k-wire therethrough.
DEVICES FOR DYNAMIC SIZING AND SAGITTAL BALANCING IN TOTAL KNEE ARTHROPLASTY
The present disclosure describes one or more embodiment of devices for assisting femoral component placement in total knee arthroplasty. The device may include a distractor configured to provide a constant distracting force. The distractor may include a main body of the distractor, a tibial paddle fixedly connected to the main body, the tibial paddle configured to engage a top of a tibia, at least one femoral paddle configured to push against a bottom of a femur, a spring housing fixed on the main body of the distractor, and a coiled constant force spring disposed in the spring housing. The spring housing is attached to an outer end of the coiled constant force spring, and the coiled constant force spring is configured to apply the constant distracting force on the at least one femoral paddle. The device further includes a mechanical apparatus for locating an isometric point of the femur.
BONE CUTTING GUIDES
Bone cutting guides and bone cutting guide assemblies are disclosed that are useful for preparing a bone in a joint space, such as those in mid-foot region joints, to prepare the cartilage end of the bone for receiving cartilage repairing implants such as hydrogel implants.
Pistol Grip Joint Tensioner
Disclosed herein are a joint distractor for joint distraction and a method for utilizing the same in a joint distraction procedure. The joint distractor may include a first surface and a second surface. The first surface may contact a first bone of a joint and the second surface may contact a second bone of a joint. The first surface may be a flexible surface that is substantially parallel to the second surface in a first position and forms an arch in a second position to distract the first bone from the second bone. A method for distracting a joint may utilize the first and second surfaces of the joint distractor.
Joint osteotomy system and method
A system includes a first spacer sized and configured to be received within a resected bone space of a first bone and a second spacer sized and configured to be coupled to a second bone. The first spacer and the second spacer each include a body extending between a bone contacting surface and a coupling surface. At least one shim is positioned between the first and second spacers. The shim includes a body extending between a first coupling surface and a second coupling surface. The first spacer, the second spacer, and the at least one shim position the first and second bones in a predetermined alignment. An adjustable guide including a guide adapter and a guide body is configured to couple to the first spacer and is adjustable on a first axis.
Bi-planar instrument for bone cutting and joint realignment procedure
A technique for correcting a bone deformity, such as a bunion, may be performed using an instrument that defines a spacer body connected to a fulcrum. The spacer body portion of the instrument can be inserted into a joint space between opposed bone ends. The fulcrum body can be inserted between adjacent metatarsals. An angle set between the spacer body and fulcrum body can help properly position both features within different joint spaces for ensuring that subsequent steps of the surgical procedure are properly performed and instrumentation is appropriately aligned.
Method of forming and decorticating a void in a sacroiliac joint
A method for forming and abrading an implant void in a sacroiliac joint (“SI Joint”) without the use of a rotary cutting instrument. The method incorporates a multimodal abrading device having abrading surfaces on opposing sides and an open tip comprising a cutting edge. The method includes the step of using the abrading head to cut bone tissue from the SI Joint at an insertion point while simultaneously using the abrading surfaces to decorticate the cortical bone at the insertion point.
