Poly-faced bone fusion implant
A bone fusion implant is provided for treating conditions of Proximal Interphalangeal (PIP), Distal interphalangeal (DIP), and metatarsophalangeal (MTP) foot joints. The bone fusion implant may be a cortical bone allograft sized to fuse the foot joint to be treated. A proximal portion of the implant may be pressed into a hole drilled in a proximal bone portion of the foot joint, and a distal portion of the implant may be pressed into a hole drilled in a distal bone portion of the foot joint. Ramps on the proximal and distal portions facilitate press-fitting the implant into the holes in the bone portions. Side ramps ensure that the bone fusion implant remains substantially aligned with the foot joint while the distal portion is pressed into the hole into the distal bone portion. Grooves on the ramps alleviate pressure and ease inserting the implant into the holes in the bone portions.
DEVICES AND SYSTEMS FOR PREPARING THERAPEUTIC PELLETS
Devices and methods for mixing and preparing therapeutic pellets are described. In one aspect, the present disclosure may include a medical device for mixing and preparing pharmaceuticals. The medical device may include a body sized and shaped to be supported by a human hand. The body may be elastically flexible between a relaxed shape and a flexed shape. In the relaxed shape, the body may form a basin and may be shaped and sized to receive a vessel for mixing or forming the therapeutic pellets. In the flexed shape, the bowl may be configured for controlled pouring of the therapeutic pellets.
BONE GRAFT AND METHOD OF MAKING AND USING SAME
A spinal bone graft includes one or more cortical bone portions forming a first unit. The first unit includes an engagement surface for contacting bone, and a mating surface. The mating surface forms at least one first undercut. The bone graft also includes one or more cortical bone portions forming a second unit. The second unit includes an engagement surface for contacting bone, and a mating surface. The mating surface forms either at least one second undercut, or at least one connector. In the former, at least one connector is received in each of the first and second undercuts to interconnect the first and second units. In the latter, the at least one connector of the second unit is received in the first undercut of the first unit to interconnect the first unit and second unit.
IMPLANT FOR BONE-GRAFT AND A METHOD FOR BONE-GRAFTING USING THE SAME
An implant for bone-graft insertedly placed in a procedure pore, the implant includes a bone organism having a lump shape, and a protective film coated to cover an overall outer surface of the bone organism as to form an absorbent membrane. After the implant is insertedly placed in the procedure pore, the absorbent member is absorbed into a body and dissolved as time passes. The implant for the bone-graft may be applied to diverse procedures performed for hone-graft not only in a dental surgery but also in orthopedics or a plastic surgery.
Crafting of cartilage
The invention is directed to producing a shaped cartilage matrix isolated from a human or animal where the cartilage has been crafted to facilitate disinfection, cleaning, devitalization, recellularization, and/or integration after implantation. The invention relates to a process for repairing a cartilage defect and implantation of a cartilage graft into a human or animal by crafting the cartilage matrix into individual grafts, disinfecting and cleaning the cartilage graft, applying a pretreatment solution to the cartilage graft, removing cellular debris using an extracting solution to produce a devitalized cartilage graft, implanting the cartilage graft into the cartilage defect with or without an insertion device, and sealing the implanted cartilage graft with recipient tissue. The devitalized cartilage graft is optionally recellularized in vitro, in vivo, or in situ with viable cells to render the tissue vital before or after the implantation. The devitalized cartilage graft is also optionally stored between the removing cellular debris and the recellularizing steps.
Shape-memory-actuated materials for accelerated healing of orthopedic injuries
A three component system for repairing critically sized bone defects having a first shape memory polymer (SMP) component formed as a scaffold that fills the defects, a second SMP component formed as a restricting sleeve that stabilizes and supports osseointegration and osteoconduction, and a third SMP component formed as a two-dimensional cell culture substrate for engineering periosteal grafts.
SKELETAL-HOLE PLUG FORMED BY HARDENED BONE CEMENT
A skeletal-hole plug comprising a hardened bone cement, which has a circular or polygonal column, and the column is a porous hardened bone cement with a porosity of 30% to 90% by volume, which can be used to rapidly fill the skeletal holes resulted from the removal of bone screws, or from the removal of teeth, and to induce rapid growth of osteocytes in the skeletal holes.
Device to be implanted in a human or animal body for material or signal delivery or acquisition within the body, and method of implanting the device
For fixedly implanting a device for material or signal delivery or acquisition or a part of such a device in a human or animal body, an opening is provided in hard tissue of the body, the opening reaching through a hard tissue layer, e.g. through a cortical bone layer into cancellous bone underneath. The device includes a plug portion and/or a cover portion which includes a ring of a material having thermoplastic properties extending around the plug portion or on a tissue facing surface of the cover portion. The opening provided in the hard tissue has a cross section at least in the area of its mouth that is adapted to the plug or cover portion such that the plug portion can be introduced through the mouth of the opening or the cover portion can be positioned over the mouth of the opening such that the ring extends around the opening, along its wall and/or on the hard tissue surface around its mouth.
COMPOSITIONS AND METHODS FOR TREATING BONE FRACTURES
Provided herein are compositions and methods for treating bone fractures. In particular, provided herein are systems comprising carbon fiber sleeves and biocompatible polymers and the use of such systems in treating or preventing bone fractures.
Adjustable and fixed assembled bone-tendon-bone graft
The present invention has multiple aspects relating to a bone-tendon-bone graft and components thereof. Embodiments of the present invention comprise an intermediate bone block that is used to adjustably secure soft tissue (e.g., tendon) in a patient. The present invention further relates to an assembled bone-tendon-bone graft suitable for implantation in humans comprising the intermediate bone block and a length of soft tissue. In a preferred embodiment, a bone-tendon-bone graft comprises a length of soft tissue (e.g., tendon) extending from a first assembled bone block to a second bone block and then doubles back to said first assembled bone block. Depending upon the embodiment, the second bone block fixedly or slideably attaches to the length of soft tissue and facilitates it doubling back to the first assembled bone block.
