IMPLANT FOR BONE AND CARTILAGE RECONSTRUCTION
The aim of the invention is to restore the mobility of an articular end (2) of a bone (3) of a patient by means of a reconstruction implant. This implant (1), which permits reconstruction both of bone and of cartilage, comprises a grated framework (10) and a sheet (20) made of a biological tissue material, this sheet firmly covering one face (11) of the framework, while the opposite face (12) is designed to be pressed rigidly against, and firmly joined to, the end of the bone.
Methods and apparatus for treating disc herniation and preventing the extrusion of interbody bone graft
Methods for treating an annulus fibrosis having a defect include inserting a flexible device into the defect. The flexible device is advanced distally beyond an outer layer of the annulus fibrosus. The flexible device is then expanded such that a width of the flexible device is larger than the defect, where the flexible device prevents escape of nucleus pulposus through the defect. The flexible device may have at least two appendages made from a shape-memory metal. Alternatively, the flexible device may have a U-shaped structure that includes a central portion and two legs. The flexible device may also be anchored to the annulus fibrosis and/or the vertebrae.
BONE ANCHOR DELIVERY SYSTEMS
Methods of inserting and retaining interbody fusion material are disclosed. In some embodiments, the methods include inserting an anchored implant comprising a bone anchoring portion and an engagement portion. A method may also include inserting at least one bone fusion material within a disc space between two adjacent vertebral bodies. In some embodiments, a method includes driving the bone anchoring portion into an outer surface of at least one of the adjacent vertebral bodies and recessing the bone anchoring portion within the outer surface of the at least one adjacent vertebral body.
MECHANICALLY ENTANGLED DEMINERALIZED BONE FIBERS
DBM compositions, methods of making and methods of treatment with the same are provided. The DBM compositions are made from mechanically entangled bone material that does not contain a carrier. The coherent mass of mechanically entangled demineralized bone fibers can be obtained by needle punching with barbed needles, entanglement with water or air jets, or by applying ultrasonic waves to the demineralized bone fibers. A coherent mass of mechanically entangled demineralized bone fibers can also be obtained by application to demineralized bone fibers of moisture, heat and pressure provided by pressure rollers. A method of making a bone material for hydration with a liquid is also provided. The method includes subjecting demineralized bone fibers to mechanical entanglement to obtain a coherent mass of demineralized bone fibers in the absence of a carrier. A method of treating a bone cavity with a mass of mechanically entangled demineralized bone fibers is also provided. The method of treatment includes implanting into a bone cavity a coherent mass of mechanically entangled demineralized bone fibers, wherein the coherent mass of mechanically entangled demineralized bone fibers does not contain a carrier.
Bone structural device
A bone structural device including a plurality of bone structural segments (40), wherein adjacent bone structural segments (40) are pivotally connected to one another about a pivot axis, and the bone structural segments (40) are expandable in height, which is in a direction generally parallel to the pivot axis.
Labral reconstruction system and methods
A system for installing a labral graft includes placing anchors into a bone thereby immovably coupling the anchors to the bone, coupling a suture to at least one of the anchors, coupling sutures to a graft, using the sutures coupled to the graft to manipulate the graft into position and tightening the sutures, thereby coupling the graft to the bone. Additionally, the system also includes a graft installation funnel having a tapered funnel body and an annular space within the tapered funnel body that is capable of retaining a graft and easing installation of the graft. Further, the system for installing a labral graft includes a graft preparation device including a block with a longitudinal recess, the longitudinal recess having a cross section that mimics the natural shape of a tissue that is to be replaced by a graft, and suture slots.
AN IMPLANT SYSTEM FOR REPAIR OR REPLACEMENT OF TENSION CARRYING CONNECTIVE TISSUE
A link (1) for connecting two loops of a flexible tension-carrying construct (2, 2a). It solves the problem of providing effective means to connect two anchor points (7, 7a), typically on bones articulating at a joint by the flexible tension-carrying construct.
Suture-locking washer for use with a bone anchor, and method for supporting the thumb of a patient after basal joint arthroplasty, and other novel orthopedic apparatus and other novel orthopedic procedures
The invention provides surgical methods, devices, apparatus, and systems for supporting the thumb of a patient after basal joint arthroplasty. The embodiments of the invention comprise at least one index metacarpal anchor, at least one thumb metacarpal anchor, at least one sling for positioning the thumb metacarpal anchor relative to the index metacarpal anchor, and at least one anchor washer for tightening and securing the sling(s) without the need to tie the suture(s) components of the sling(s) into knots. Index and thumb metacarpal anchors comprise at least one bone-engaging element for engaging the respective metacarpal. The anchor washer may incorporate one or more sling-engagement mechanisms. Increasing the number of sling-engagement mechanisms associated with the anchor washer increases the surface area of the sling(s) and provides multiple sling elements to provide redundancy and increase the pull force of the sling(s) attachment(s) used to affix the thumb and index metacarpal anchors into a position relative to each other.
Method and apparatus for closing fissures in the annulus fibrosus
A method for closing a fissure in a region of tissue having an inner surface and an outer surface, the method comprising: providing at least a pair of transverse anchor components, each transverse anchor component being coupled to at least one flexible longitudinal fixation component having a longitudinal axis; placing the transverse anchor components relative to the inner surface of the tissue on both sides of the fissure such that an exposed end of a flexible longitudinal fixation component extends through the tissue and past the outer surface of the tissue on both sides of the fissure; applying axial tension to the exposed ends; and anchoring the exposed ends.
SOFT ANCHOR SURGICAL FIXATION DEVICE AND METHODS OF USE THEREOF
A soft anchor surgical fixation device includes two soft anchoring implants. The implants have a first elongate state where the implants may slide easily through a bone hole or tunnel, and a second axially compressed state where the implants are prevented from sliding through the bone hole or tunnel. The device also includes a suture pathway extending at least partially along and through the sidewalls of the implants. Tension on the suture transitions the implants from the first elongate state to the second compressed state.
