MINIMALLY INVASIVE SURGICAL TOOLS AND SYSTEMS
A surgical tool includes a body defining an opening sized and configured to receive a first bone portion therein, a displacement tip coupled to a first end of the body, the displacement tip sized and configured for insertion into a medullary canal of a second bone portion, and a deployable retention block configured to be transitioned from a first position to a second position. The deployable retention block is configured to maintain the first bone portion in a predetermined position when the deployable retention block is in the second position.
METHODS AND APPARATUS FOR MINIMALLY INVASIVE BUNION SURGERY
A system and method for performing a percutaneous bunionectomy. The system including a jig, which subsequent to attachment and performance of an osteotomy on the bone, uses a rack and pinion mechanism to translate the separated portion of the bone to a surgeon determined displacement λ. A locking mechanism maintains the desired displacement of the bone portions and allows the surgeon, with use of an attached visual guide, to insert a k-wire through the bone portions to serve as a guide wire for the internal fixation that maintains the displacement during the healing. The system removes the requirement that the surgeon manually maintain the desired displacement while inserting the guide wire.
ROTATIONAL GUIDED GROWTH DEVICES, SYSTEMS, AND METHODS
A tether assembly may be attached to a bone to correct a rotational deformity. The bone may have a growth plate that separates a first section of the bone from a second section of the bone. The tether assembly may have a tether member with a first end, a second end, and a central portion extending between the first end and the second end. The first end may have a closed outer wall that defines and fully bounds a first aperture. The second end may have an open outer wall that defines and partially bounds a second aperture. The open outer wall may define a slot in communication with the second aperture. The first and second ends may be securable to the first and second sections of the bone via coupling members inserted through the first and second apertures and anchored in the first and second sections, respectively.
Device and Surgical Technique for Foot Surgery
A correction clamp assembly that permits a physician to surgically correct a bunion or similar deformity is provided. The assembly includes an elongate bridge, as well as first and second blocks slidably or rotatably connected to the elongate bridge. More specifically, first block is configured to slide along a slot formed in the elongate bridge, as well as rotate relative thereto. Additionally, the second block is configured to rotate relative to the elongate bridge. First and second pins may be configured to extend through the first and second block, and then into various pieces of bone. Once a cut is made in a portion of joint or bone, the pins can thereafter be moved towards and away from one another to position the respective pieces of bone in a desired location. Locking screws may also be provided to releasably secure the blocks relative to the bridge.
Osteotomy systems, devices and methods
Osteotomy systems, devices, and methods for using the osteotomy systems are disclosed. The osteotomy system including an alignment device, at least one k-wire for insertion into the alignment device, and a cut guide with at least one hole for receiving at least one k-wire and a slot for receiving a saw blade. An osteotomy kit including an alignment device, cut guide, and position rotation device. The alignment device, cut guide, position rotation device, and bone plate are also disclosed. Finally, a method for fusing bones using the osteotomy system is also disclosed.
Suture system and method
A suture system including a suture construct having a first reduction construct configured to be selectively arranged in an expanded state and a reduced state. The first reduction construct includes a first locking limb, a first contractible loop, and a first opposed loop disposed generally opposite to the first contractible loop, wherein reduction of the first opposed loop contracts the first contractible loop from the expanded state into the reduced state and secures the suture construct in the reduced state. The suture construct may also include a second reduction construct. Optionally, the suture system includes a first and a second pusher tube defining a first and a second lumen, respectively, wherein each pusher tubes are advanced over portions of opposed loops, respectively, and wherein distal portions of opposed loops extend beyond the pusher tubes, respectively.
Joint spacer systems and methods
In some examples, a method for preparing one or more bones involves inserting a spacer into a space defined between a first bone and a second bone, such as a joint space between a first metatarsal and medial cuneiform. A bone preparation guide can be aligned with opposed ends of the first bone and the second bone using the spacer as an alignment reference. For example, the bone preparation guide may include an opening such that the guide can be installed across the joint space with the spacer received in the opening. A clinician may use the bone preparation guide to guide a tissue removing instrument to cut or otherwise prepare the ends of the first bone portion and second bone portion.
MINIMALLY INVASIVE TOOLS, SYSTEMS AND METHODS
A system includes a first tool having a base, a nut, and a tool guide. The base extends from a first end to a second end and includes at least one thread disposed along a length thereof. The first end includes a foot having a widthwise dimension that is greater than a diameter of the at least one thread. The nut is configured to be disposed along the length of the base and to engage at least one thread. The tool guide is configured to be slideably disposed along the length of the base and has a body including a flange portion. The flange portion defines an opening for receiving at least one of a pin and a cutting tool. Rotation of the first nut causes the nut to translate along the length of the base thereby causing the tool guide to move along the length of the base.
COMPRESSOR-DISTRACTOR FOR ANGULARLY REALIGNING BONE PORTIONS
A compressor-distractor device may be used during a surgical procedure, such as a surgical procedure to correct a bunion deformity. In some examples, the compressor-distractor includes first and second engagement arms having first and second pin-receiving holes, respectively. The first and second pin-receiving holes may be angled relative to each other. The compressor-distractor may also include an actuator operatively coupled to the first and second engagement arms. In some example uses, a clinician may pin a first surgical device to a patient's bones use a pair of parallel pins. After removing the surgical device over the parallel pins, the clinician may thread the parallel pins through the angled first and second pin-receiving holes of the compressor-distractor, causing the bones to move relative to each other. Thereafter, the clinician may actuate the actuator on the compressor-distractor to move the bones towards and/or away from each other.
IMPLANTS, DEVICES, SYSTEMS, KITS AND METHODS OF IMPLANTING
A distraction kit including at least one trial insert, at least one handle for coupling to the at least one trial insert, a correction indication guide, and at least one implant. A method for performing a distraction arthrodesis including inserting at least one trial insert into a joint and selecting a trial insert of the at least one trial insert for correction of the joint in a first plane. The method also including rotating the selected trial insert in a medial-lateral direction for correction of the joint in a second plane and selecting the needed correction in the first plane and the second plane. The method further including marking at least one bone for the selected correction. Then, marking the implant with the correction indication guide to achieve proper placement of the implant and joint correction replication from the desired trial positioning. Implants, devices, and systems are also disclosed.
