Implants
An implant assembly includes a first implant member, a second implant member, and a contractible element that is connected between the first and second implant members. The first implant member is configured to be placed against a first bone portion, and the second implant member is configured to be placed against a second bone portion. The contractible element is fixed at a first end to one of the first and second implant members, and movable at a second end with respect to one of the first and second implant members so as to induce tension in the suture, thereby providing a compressive force against the first and second bone portions. The second end can then be fixed with respect to the first and second implant members. The contractible element can contract in length in response to bodily fluids, thereby ensuring adequate post-operative compression. An instrument is also disclosed that is configured to implant the first and second implant members adjacent the first and second bone portions, respectively.
Meniscus prosthetic devices with anti-migration or radiopaque features
A prosthetic device for use as an artificial meniscus is disclosed. The prosthetic device restores stress distribution, stability, and function to the knee joint after removal of the damaged natural meniscus. In some embodiments, the prosthetic device includes an anti-migration feature that inhibits extreme movement within the joint while permitting free floating over a significant range. In one aspect, the anti-migration feature is an enlarged anterior structure or a posterior meniscus remnant engaging channel while in another aspect, the anti-migration feature includes a tethering member. Still further, removable radiopaque features are provided to enhance trialing of the implant prior to final implantation within the joint.
SURGICAL REDUCTION TOOLS AND METHODS FOR ACHIEVING BONE COMPRESSION
Surgical reduction tool assemblies may be used for achieving compression between bone fragments or across joints when performing arthrodesis procedures, bone fracture procedures, etc. The reduction tool assemblies may be used to reduce a gap between bone fragments or between bones of a joint prior to attempting to achieve final compression with a bone plate.
Fracture fixation device
Assemblies for securing fractured bone are provided. The assembly includes a first fixation element, a second fixation element, and an adjustable flexible member construct. The first fixation element having a male or a female sleeve is secured within a first portion of the fractured bone. The second fixation element having the other of the male or female sleeve telescopically received within the one of the male or female sleeve is secured within a second portion of the fractured bone. The adjustable flexible member construct extends between the first and second fixation elements and has at least one adjustable loop coupled to the first fixation element and the second fixation element and a pair of adjusting ends extending through an opening in the first fixation element. The pair of adjusting ends can be pulled to reduce a diameter of the adjustable loop and to compress fragments of the fractured bone.
TIBIAL PLATEAU LEVELING OSTEOTOMY PLATE
A TPLO plate configured to accommodate flexible strands (flexible loops) attached to tissue to be attached to bone. The TPLO plate has one or more suture eyelets, to allow the user (surgeon) to pass a flexible strand through the eyelets and attach/reattach the tissue to the plate at the anatomical location, and to improve the rotational stability of the joint or bone. The eyelets may have various shapes, forms and configurations and may be provided on or within a surface of the TPLO bone plate in any number, depending on the characteristics of the fractured bone or bone segments, or of the plate design. The eyelets preferably receive one or more flexible strands.
Surgical Suture System, Tissue Restraints, and Tissue Anchors
A surgical suture system, tissue restraint/suture capture and tissue anchor for tissue repair and reattachment of torn tissue to a tissue substrate, medical, veterinary or dental prosthesis or medical implant. The system includes a plurality of tissue restraints/suture captures which each include a central locking aperture sized and configured to receive a beaded suture member passed therethrough which minimizes longitudinal tensioning and/or restraining movement, the “GO” force, of a beaded suture member in the forwardly direction through the locking apertures for suture tightening and which maximizes “NO-GO” force to pull the suture in the reverse direction. Uniquely configured tissue anchors and other medically implantable devices securely receive one of the tissue restraints/suture captures for tensioning of a suture member between tissue and the tissue anchor.
FLEXIBLE FASTENING BAND CONNECTOR
A flexible fastening band connector can comprises a recess to receive a distal end portion of a flexible fastening band and lumen to receive the proximal end portion of the flexible fastening band. The lumen guides the proximal end portion of the flexible fastening band toward a fastening mechanism. The flexible fastening band connector can comprise an opening to receive a spinal rod. In operation, the spinal rod is coupled to additional devices to secure the spinal rod to portions of one or more vertebra. In some embodiments, a method of performing an operation, e.g. a spinal operation, on a patient using the disclosed connector is provided.
Surgical Method of Stabilizing Bone or Joint Fracture Using Flexible Line
A surgical method for stabilizing a fractured bone, comprises optionally realigning two portions of the bone impacted by the fracture, followed by drilling a hole through at least the first portion of bone and preferably the second portion of bone across the interface defined by the fracture. A flexible thread is threaded forward through the hole and a rear section of the thread anchored to the first portion of bone. The thread is pulled taut, holding the first bone portion relative to the second bone portion in a healing position. With the thread taut, a front section of the thread is anchored relative to the bone, thereby maintaining the first bone portion and second bone portion in the healing position.
Method and apparatus for stitching tendons
Methods and apparatuses for repairing a tear in soft tissue are disclosed. A method according to the principles of the present disclosure includes connecting an intermediate member to a bone anchor and placing the intermediate member on the soft tissue. The method further includes inserting a first suture through the intermediate member and the soft tissue to attach the intermediate member to the soft tissue and fixing the bone anchor to bone to secure the soft tissue to the bone.
Sternum fixation device and method
An apparatus and technique for infernally securing a plurality of bone segments together. The device incorporates a plate-like structure stabilizing the fracture and integrated fasteners to attach straps circumscribing the bone segments.
