SYSTEMS, METHODS, AND APPARATUS FOR SPINAL DEFORMITY CORRECTION
Methods for correction of spinal deformities using bone anchors having one or more features configured to actively draw in and/or compact vertebral bone into an inner chamber. In some implementations, a first bone anchor having an inner chamber may be advanced into a first vertebral body of a spinal column. One of more features of the inner chamber may, as the first bone anchor is rotatably or otherwise advanced, actively draw and compact vertebral bone into the inner chamber. A second bone anchor may be advanced into a second vertebral body of the spinal column, after which a tether may be coupled between the first and second bone anchors to apply a corrective force to at least a portion of the spinal column.
Knotless labral repair techniques and related devices
A suture anchor for use in a knotless, suture-first technique for securing soft tissue to bone comprises a proximal anchor body and a distal tip having an eyelet configured to receive an end of a repair suture. Internal locking elements on the distal tip and the proximal anchor body are provided for locking the tip and anchor body together when the suture anchor is implanted in a bone. A suture assembly for use in an alternate knotless technique comprises a suture anchor, a repair suture, and a shuttle suture. Both the repair suture and the shuttle suture rea looped at one end and straight at the other end. In the alternate technique, the loop and tail of the repair suture are manipulated to form a luggage tag configuration extending around the tissue, and the shuttle suture is used to tightly secure the luggage tag configuration and tissue against the bone.
SYSTEMS, METHODS, AND APPARATUS FOR SPINAL DEFORMITY CORRECTION
Bone anchors and related systems and methods for spinal deformity correction. In some implementations, two adjacent bone anchors may be advanced into respective, adjacent vertebral bodies of a spinal column. Cancellous bone may be compacted within respective inner chambers of the bone anchors. The inner chambers may comprise at least one of a plurality of bone engaging protrusions and a profile that increases in cross-sectional area, at least in part, from a proximal end of the inner chambers to a distal end of the inner chambers. A tether may then be coupled between the first and second bone anchors to apply a corrective force to at least a portion of the spinal column.
Composite interference screws and drivers
The present disclosure relates to an anchor. The anchor includes a suture bridge having a proximal end and distal end. The distal end of the suture bridge has a thickness greater than a thickness of the proximal end of the suture bridge. At least two ribs extend from the proximal end of the suture bridge to a proximal end of the anchor. At least one open helical coil wraps around the at least two ribs and extends, substantially, from the proximal end of the suture bridge to the proximal end of the anchor. The at least one open helical coil defines an internal volume communicating with a region exterior to the anchor through apertures between turns of the at least one open helical coil. The at least two ribs are engagable with a grooved shaft of a driver.
SURGICAL VESSEL CLOSING PRESSURE DEVICE
Various embodiments include a vessel clamping pressure device that is configured to receive suture threads extending from the closure of a vascular vessel of a patient, and maintaining tension on suture threads between the patient and the vessel clamping pressure device to apply pressure to the patient so as to apply a clamping pressure to the vascular vessel to facilitate clotting. In some embodiments, a pressure applying surface may include a cushioning material configured to cushion application of the pressure applying surface the patient.
Slack reducing suture anchor assembly and method of tissue repair
Surgical anchor assemblies and method of tissue repair using the same. The surgical anchor assemblies have a cannulated fixation device, an implant configured to be coupled to the fixation device, and a stop mechanism for preventing relative movement between the fixation device and the implant, such that the fixation device and the implant are configured to rotate together, and a flexible strand winds up to reduce any slack in the flexible strand used for the repair.
COMPRESSION AND TENSION INSTRUMENTS AND METHODS OF USE TO REINFORCE LIGAMENTS
The disclosure provides apparatus and methods of use pertaining to syndesmosis reinforcement. Embodiments include a clamp having two jaws that extend toward each other to clamp two bone portions therebetween. The clamp may include an angle gauge and an adjustment mechanism having a force gauge that combine to enable the compression of the two bone portions in an optimal direction or angle and at an optimal, measurable compression force. Embodiments also include a tension instrument configured to knotlessly lock a flexible strand construct between two anchors at the same optimal direction and tension applied by the clamp. Further embodiments include an exemplary syndesmosis reinforcement procedure that employs the clamp and the tension instrument to construct a ligament reinforcement construct that achieves optimal anatomic positioning in both directional alignment and the reduction force applied by the construct. Other embodiments are disclosed.
Syndesmosis construct
A knotless button includes a body defining a proximal portion and a distal portion. The body further defines an internal cavity and a first loop opening extending from the internal cavity to an outer surface of the body. A locking insert is slideably positioned within the internal cavity. The locking insert defines a second loop opening extending from a first side of the locking insert to a second side of the locking insert. The locking insert is slideably moveable from a first position to a second position within the internal cavity. A flexible strand defines a first adjustable loop extending through the first loop opening and the second loop opening. The locking insert is slideably moveable from a first position configured to allow adjustment of the first adjustable loop to a second position configured to lock the first adjustable loop.
BONE ANCHORS AND SCREWS
The variable or adjustable depth medical implants disclosed herein are cable of depth adjustment prior to implantation. The variable depth implants permit a single implant to provide multiple footprint configurations, allowing a surgeon adjustability in the operating room. The implants can comprise a metallic lattice designed for specific physical properties, such as an elastic modulus. In some examples, the main body of the implant is taller than the adjustable portion of the implant so that the physical properties of the main body of the implant are controlling at the implant site. In some embodiments, the variable implant is constructed in an additive process as a single unit.
Disclosed herein is, in some embodiments, a multi-segment bone anchor configured to allow variable bone ingrowth or attachment between each segment. In some versions, a lower segment is configured to allow bone ingrowth and a detachable upper segment is configured to prevent bone ingrowth, making the bulk of the bone anchor removable.
CANNULATED SUTURE AND/OR GRAFT ANCHOR
The present disclosure provides a system, method, and cannulated anchor for treating acute or chronic instability of two boney structures in a patient. The provided cannulated anchor includes an opening through which suture, and in some instances a tendon graft, may be positioned. The cannulated anchor also includes a securing mechanism that helps maintain its position when installed in bone, such as flexible prongs, angled tabs, or ridges. The cannulated anchor is installed by being translated over a k-wire with a cannulated inserter that engages the cannulated anchor. The k-wire passes through the tendon graft, if used, as the cannulated anchor is translated over the k-wire. Passing the k-wire through the tendon graft allows the tendon graft to take up more space within the cannulated anchor's opening versus being biased to one side of the k-wire during insertion.
