| Title: | Orthopedic Fixation Device With Bioresorbable Layer |
| Family: | Patent family and legal status for 8,506,608 |
| INPADOC Status: | Active |
| Inventor(s): | Cerynik, Douglas (Wynnewood, PA), Harding, Susan P. (Galloway, NJ) |
| Publication Number: | 8506608 |
| Application Number: | 12/730661 |
| Abstract: | An orthopedic screw is used in a fixation device for treating fractures. The device has a body with holes to accept the bone screws. The bone screws have a layer of bioresorbable material on the shaft. Engagement between the bone screws and the body is initially through the bioresorbable material, which engagement rigidly fixes the relative angular orientation between the bone screws and the body when the device is applied to a bone. As the bioresrobable material is resorbed the angular relation between the bone screws and the body is no longer rigidly fixed, thereby effecting a transformation from rigid osteosynthesis to flexible osteosynthesis to allow micromotion between the bone fragments which promotes healing. |

| Application Number: | 09/289000 |
| Abstract: | A method for treating a non-weight bearing arthritic joint involves resecting at least one of the opposed joint surfaces to expose a cancellous bone surface. A bioresorbable implant is mounted to one of the joint surfaces so that the resected joint surface rubs against the surface of the implant. This causes the fibroblast to change into fibrocartilage at the resected bone surface as the implant is resorbed thereby effectively replacing the implant with fibrocartilage during such resorption. |

| Title: | Resorbable Scaffolds To Promote Cartilage Regeneration |
| Family: | Patent family and legal status for 6,530,956 |

| Inventor(s): | Mansmann, Kevin A. (Paoli, PA) |
| Publication Number: | 6530956 |
| Application Number: | 09/393522 |
| Abstract: | A load-sharing resorbable scaffold is used to help transplanted chondrocytes or other cells generate new cartilage in a damaged joint such as a knee, hip, or shoulder. These scaffolds use two distinct matrix materials. One is a relatively stiff matrix material, designed to withstand and resist a compressive articulating load placed on the joint during the convalescent period, shortly after surgery. Due to the requirement for relatively high stiffness, this material must be denser and have less pore space than other matrices, so it will not be able to support highly rapid cell proliferation and cartilage secretion. The second material comprises a more open and porous matrix, designed to promote maximal rapid generation of new cartilage. In one preferred geometric arrangement, the stiffer matrix material is used to provide an outer rim and one or more internal runners, all of which can distribute a compressive load between them. The rim and runners create a cluster of internal cell-growing compartments, which are filled with the porous and open matrix material to encourage rapid cell reproduction and cartilage generation. These improved scaffolds can also have an articulating outer membrane with certain traits disclosed herein, bonded to and resting upon the upper edges of the runners and rim. The scaffold will support the membrane with a degree of stiffness and resiliency that allows the membrane to mimic a healthy cartilage surface. These scaffolds can be made of flexible materials, to allow them to be inserted into a damaged joint using arthroscopic methods and tools. |

| Application Number: | 09/364420 |
| Abstract: | An anatomic, neck-locking femoral prosthesis for use in total hip replacement is described. The asymmetric device fundamentally comprises a shell with a hollow bell-shape, which is anchored on the outside of retention neck and the trochantic bed of the femur. The prosthesis is mechanically fastened during the operation and further biologically secured by in-growing bone around the neck and trochantic bed area through the side holes on the shell and by growing into its interior porous coating surface of implant thereafter. The loading force on the femoral head would be well distributed on the shell and directly conducted into the cortex bone of the femoral shaft through the shell. The prosthesis would provide a simple and safe replacement method of hip prosthesis for most patients, particularly benefit for younger patient who has a defective head of femur. Because of less changes in term of anatomic structure of femur, new device could eliminate most of side effects and complications, which appear in regular stem type prosthesis of THA and thereafter. |

| Publication Number: | 6187008 |
| Application Number: | 09/349303 |
| Abstract: | An implant has a threaded end for screwing into a bone on one side of a joint and an extending resorbable polymer shaft for crossing the joint. The resorbable shaft is fixed in a bone on the opposite side of the joint. The present invention avoids joint stiffness by allowing slight movement of the bones relative to one another initially while the soft tissues heal. As the shaft resorbs, it allows progressively more motion in the joint so that the articular surfaces are not degraded from lack of motion. Eventually, the shaft is completely resorbed thus requiring no removal operation. The implant of the present invention also finds application in bridging a bone fracture to allow progressive load shifting to the bone during healing. |

| Publication Number: | 6017366 |
| Application Number: | 08/844486 |
| Abstract: | A resorbable implant for interposition arthroplasty which is intended to fill a void between two adjacent bone ends, providing a cushion between the bone ends to prevent impingement of the bone ends while providing time for tissue to infiltrate into the space occupied by the implant. It has a protracted resorption time of preferably at least three months to allow time for the proliferation of load-bearing host fibrous tissue in place of the resorbed implant material. The implant preferably is porous with a pore size of greater than about 80 microns in order to enhance infiltration of fibrous tissue. The implant has a modulus in the range of 0.8 to 20 MPa which is soft enough to allow it to conform to surface irregularities of the adjacent bone surfaces while being hard enough to maintain a desired separation between those bones while tissue infiltration replaces the resorbable implant material. The implant may be preformed to the desired shape or alternatively may be formable by the surgeon by methods such as carving with a scalpel. A preferred application for the implant is as a trapezium bone replacement. |

| Abstract: | The element (20) according to the invention comprises a biodegradable body which is before or during the implantation of an orthopaedic prosthesis (1) inserted into a recess (2) in the prosthesis (1) such that the rigidity of the prosthesis is increased. The element (20) provides mechanical connection between the shell segments (1a, 1b, 1c) so that the element (20) performs a supporting function which reduces the elastic properties or the possibilities of movement of the outer shell (1). The ability of the biodegradable element (20) to transfer forces is increasingly reduced after the implantation so that the outer shell (1) of the artificial acetabulum has increasingly more elastic properties depending on the mechanical properties determined by the structure. Some time after the implantation, the biodegradable element (20) degrades so much that it no longer transfers any forces. |

| Publication Number: | 20090177282 |
| Application Number: | 11/813827 |
| Abstract: | Bone tissue at the interface of a bone implant is shielded from stresses found in normal bone because of the higher stiffness or rigidity in the implant versus in bone. The resulting "stress shielding" of the bone by the implant eventually results in resorption of bone at the bone-implant interface and ultimately necessitates replacement of the bone implant. To overcome these problems, an implantable biomimetic prosthetic bone having a porous surface, a fiber-reinforced composite structure, and a polymer-based core is disclosed. The prosthetic bone is a good match for structure, stiffness, viscoelastic properties, specific weight and overall structure as real bone or host tissues adjacent to the prosthetic bone. The prosthetic bone may be formed as a total hip prosthesis. |

| Abstract: | An implant composite material is provided which is for use in the treatment of articular cartilage disorders such as hip joint femur head necrosis and knee joint bone head necrosis, the reconstruction/fixing of a bio-derived or artificial ligament or tendon, the uniting/fixing of a bone, etc. Part of the implant composite material is replaced by bone tissues in an early stage to enable the material to stably bond with a living bone, while the other part retains a necessary strength over a necessary time period. Finally, the implant composite material is wholly replaced by the living bone and disappears. It is an implant composite material having a constitution which comprises a compact composite of a biodegradable and bioabsorbable polymer containing bioabsorbable and bioactive bioceramic particles and a porous composite of a biodegradable and bioabsorbable polymer containing bioabsorbable and bioactive bioceramic particles, the porous composite being united with the compact composite. The porous composite is replaced by bone tissues in an early stage to enable the material to stably bond with a living bone, while the compact composite retains a necessary strength over a necessary time period. Finally, the material is wholly replaced by the living bone and disappears. Consequently, this implant composite material can sufficiently meet desires in this medical field. |

| Abstract: | To change a spatial relationship between two or more bones in a patients body, a wedge member is moved into a joint between the bones. As the wedge member enters the joint, pivotal movement occurs between the bones to change the orientation of the bones relative to each other. The wedge member may have a circular cross sectional configuration and be moved into the joint by rotating the wedge member about an axis which extends between a thin leading edge portion and a thick trailing edge portion of the wedge member. Alternatively, the wedge member may have a cam-shaped configuration and be rotated through less than a revolution to apply force against the bones. The wedge member may have a porous construction which enables bone to grow through the wedge member and immobilize the joint. The wedge member may be coated with and/or contain bone growth promoting material. The wedge member may be connected to only one of the bones or may be connected to two adjacent bones. If the wedge member is connected to only one bone, the joint may be capable of being flexed after the wedge member is inserted into the joint. |

| Abstract: | This invention is a method for the implantation of a combination of cells or cell-microcarrier aggregates wherein one component comprises a solid implantable construct and a second component comprises an injectable formulation. For example, in one embodiment, the solid implant may be first implanted to fill the majority of the cavity receiving the implant, and then cells or cell-microcarrier aggregates in an injectable format, with or without the addition of gelling materials to promote rapid gelling in situ, may be injected into spaces surrounding the solid implant in order to secure the solid implant in the site and/or to promote rapid adherence and/or integration of the solid implant to surrounding tissues. Also contemplated in this embodiment is that the cellular composition of the injectable component may differ from that of the solid component. For example, the solid implant may result from the culturing of chondrocytes on microcarriers or scaffolds, thereby resulting in an implant having cartilage-like properties, whereas the injectable cells or aggregates may result from the culturing of stem cells, resulting thereby in cells capable of producing cells of a chondrogenic, fibroblastic, myoblastic or osteoblastic phenotype. In this example, cells in the injectable aggregates may promote the fixation to or rapid integration of the solid cartilage implant into surrounding cartilage, connective tissue, muscle or bone, respectively. |
