A device for containing bone graft material comprises a body including an inner sleeve extending longitudinally from a proximal end to a distal end and an outer sleeve surrounding the inner sleeve and extending longitudinally from a proximal end to a distal end such that a bone graft collecting space is formed therebetween.

A system for repairing a defect on an articular surface of a patient's trochlear region, the system comprising a guide block comprising a body having an exterior surface configured to engage with the saddle portion and ridge portions of the patient's trochlear region, a protrusion extending generally from the body and configured to be received in a first bore formed in the articular surface along a reference axis, and a first cavity extending through the body configured to establish a first working axis displaced from the reference axis, wherein the exterior surface of the body and the protrusion are configured to secure the location of the guide block about the patient's trochlear region. A method for preparing an implant site in bone, comprising: establishing a reference axis extending from the bone; creating a bore in the bone by reaming about the reference axis; securing a guide block about the articular surface; establishing a first working axis extending from the bone using the guide block, the first working axis is displaced from the reference axis; and creating a first socket in the bone by reaming about the first working axis, wherein the first socket partially overlaps with the bore.

Surgical tools and kits are disclosed for repairing hyaline or meniscal cartilage, using membrane segments to protect and promote the growth and activity of cartilage-generating cells. These kits include: (i) a set of dilator tubes, adapted from similar tubes used in spinal surgery except shorter, that will allow a surgeon to progressively enlarge an insertion tunnel for inserting a membrane segment into an articulating joint that is being repaired; and, (ii) an assortment of membrane tamping devices, with smooth rounded tamping heads (or tips, etc.), and with a size and length that allow the tool tip to pass through the longest dilator tube while being held by the surgeon. Additional components (including disposable supplies) that can help facilitate these types of surgery can be included in any such kit, or in supplemental kits that can be bundled and shipped with these primary kits.

The present invention is directed to a system comprising a medical instrument (e.g. cup implant, 3) and a holding device (2) that interacts with said medical instrument to form a sealable cavity within the combined arrangement of components. An impaction device (1) is also provided, preferably which provides means to allow fluid to be expelled from the cavity but which prevents further fluid from entering the cavity.

The present disclosure includes apparatuses for a bone graft harvesting device. An example apparatus includes a blade tip including a proximal end and a distal end, wherein the distal end of the blade tip includes a number of blades configured to morcellate bone in response to being rotated and a lead tip located within the blade tip and configured to maintain the bone graft harvesting apparatus centered on a bone graft punch hole.

Methods of harvesting cancellous bone and bone marrow include extracting loosened cancellous bone and bone marrowincluding a liquid component thereofto a collection container that has a first cup and a suction port to which a suction source is connected. After extraction, the suction source is disconnected and a lid of the collection container is removed and replaced with a lid having a plunger with a press head that is configured to filter the extracted liquid by depressing the plunger toward a bottom of the first cup. The filtered liquid is poured through a suction port into a second cup while depressing the plunger, thereby separating the liquid from a semi-solid mass of cancellous bone that remains. The bone is extracted through a cortical opening in the femur, tibia, or calcaneus, or from an intermedullary canal that is preferably formed by reaming of the tibia using an orthopedic reamer.

A decompression device and method for removing marrow and other fluid from an intramedullary canal. The decompression device includes a cannula having a channel that allows fatty marrow to pass therethrough. A first port extends from the device and is in operable connection to a vacuum source that creates suction for removing fluid from the intramedullary canal. In some embodiments, one or more fenestrations are disposed along the second end of the cannula to expedite the removal of the fluid. In operation, the cannula is inserted into the intramedullary canal of a femur. Once fatty marrow is removed from the intramedullary canal, the cannula is removed and a reaming device is inserted into the femur. In this way, the fatty marrow is removed prior to the reaming procedure in order to prevent these fluids from traveling to the lungs causing blockage that leads to severe cardiorespiratory and vascular dysfunction.

An articular ball impactor having a heat resistant material used during heat shrink fit process for providing secure fixation of Morse taper components in modular orthopedic implants. The female Morse component of the articular ball is heated by electromagnetic unit providing thermal expansion. Subsequently, it is impacted over the male Morse taper component and then cooled by commonly used sterile irrigation fluid allowing the female Morse component to shrink thus providing considerable compression, fit and significant reduction of micromotion that has been so widely responsible of fretting and mechanical corrosion.

An implant for repairing an articular cartilage defect site including an implant fixation portion with an upper segment and at least one bone interfacing segment and a top articulating portion with an articulating surface and an engagement surface. The upper segment includes a supporting plate with a first locking mechanism segment. The engagement surface includes a second locking mechanism segment. The first locking mechanism segment with at least two channels is structured to couple to the second locking mechanism segment with at least two protrusions. The at least one bone interfacing segment structured for insertion into the articular cartilage defect site. An implant including an implant fixation portion, a top articulating portion, and a locking mechanism with a first locking segment coupled to the upper segment and a second locking segment coupled to the at least one engagement surface and structured to couple to the first locking segment.
