System for fixing cervical vertebrae, an apparatus for fixing cervical vertebrae and a driver used for an apparatus for fixing cervical vertebrae
A fixing apparatus for cervical vertebrae in which in which a fixing plate is made to be in proximity with cervical vertebrae and screws are inserted into the cervical vertebrae through screw holes formed in the fixing plate, includes an opening and closing member that opens and closes the screw holes while being moved between a closing position for covering the screw holes and an opening position for opening the screw hole on the fixing plate.
Orthopedic screw extractor
An orthopedic screw extractor device including a shaft, an end portion about a first end of the shaft for securing to a handle, and a screw extracting tip about a second end of the shaft opposite the first end. The screw extracting tip further includes a generally frustoconical shape having a side at an angle of about 5 to 15 degrees relative to a longitudinal axis of the screw extracting tip. The screw extracting tip further includes first, second and third screw threads and first, second and third flutes circumferentially spaced about the screw extracting tip and extending across an entire length of the screw extracting tip. Each of the screw threads has a lead of about 0.07 to 0.12 inches, a pitch of about 0.02 to 0.04 inches, a thread angle of about 40 to 50 degrees, and a depth of about 0.01 to 0.02 inches.
Low profile spinal tethering devices
Methods and devices for treating spinal deformities are provided. In one exemplary embodiment, a low-profile spinal anchoring device is provided for receiving a spinal fixation element, such as a tether, therethrough. The device generally includes a staple body that is adapted to seat a spinal fixation element, a fastening element for fixing the staple body to bone, and a locking assembly for coupling a spinal fixation element to the staple body. In one embodiment, the locking assembly includes a washer that is adapted to couple to the staple body such that the spinal fixation is disposed therebetween, and a locking nut that is adapted to engage the staple body to mate the washer to the staple body.
SPINAL IMPLANT SYSTEM AND METHOD
A surgical instrument comprises a first member including a drive engageable with a first mating surface of a bone fastener. A second member is rotatable relative to the first member and includes an element engageable with a second mating surface of the bone fastener. An actuator is connected with the second member and includes visual indicia of engagement of the element with the second mating surface. Systems, spinal implants and methods are disclosed.
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.
VARIABLE ANGLE ORTHOPEDIC FASTENERS FOR FIXATION OF AN ORTHOPEDIC IMPLANT
Systems for variable angle insertion of surgical fasteners relative to an orthopedic plate with locking of the surgical fastener relative to the plate upon insertion. The systems may include a pivot member secured relative to either the orthopedic plate or the fastener. In either regard, the pivot member may provide locking engagement with the plate to lockingly engage the fastener relative to the plate.
PROXIMAL INTERPHALANGEAL FUSION DEVICE
The various embodiments of the present invention provide a system, including methods, apparatus and kits for connecting bones and/or bone portions using a multi-part bone connector with one or more rotating joints.
HUMERAL IMPLANT ANCHOR SYSTEM
A stemless humeral shoulder assembly having a base member and an anchor advanceable into the base member. The base member can include a distal end that can be embedded in bone and a proximal end that can be disposed at a bone surface. The base member can also have a plurality of spaced apart arms projecting from the proximal end to the distal end. The anchor can project circumferentially into the arms and into a space between the arms. When the anchor is advanced into the base member, the anchor can be exposed between the arms. A recess can project distally from a proximal end of the anchor to within the base member. The recess can receive a mounting member of an anatomical or reverse joint interface.
EXTRACTOR DEVICE
An orthopedic screw extractor device including a shaft, an end portion about a first end of the shaft for securing to a handle, and a screw extracting tip about a second end of the shaft opposite the first end. The screw extracting tip further includes a generally frustoconical shape having a side at an angle of about 5 to 15 degrees relative to a longitudinal axis of the screw extracting tip. The screw extracting tip further includes first, second and third screw threads and first, second and third flutes circumferentially spaced about the screw extracting tip and extending across an entire length of the screw extracting tip. Each of the screw threads has a lead of about 0.07 to 0.12 inches, a pitch of about 0.02 to 0.04 inches, a thread angle of about 40 to 50 degrees, and a depth of about 0.01 to 0.02 inches.
THREADED SUTURE ANCHOR
The present disclosure relates to a suture anchor. The suture anchor includes a body having a proximal end and a distal end, the body including threads along at least a partial length of the body and at least one through hole, the threads including a profile such that the threads located near the distal end of the body include a first shape and the threads located near the proximal end of the body include a second shape different from the first shape. Delivery devices and anchor dilators are also disclosed.
