  • Patent number: 10932913
    Abstract: A multi-layered prosthetic element comprises a central body (1; 1?) of a substantially truncated conical shape and having a through axial cavity (2; 2?) open at both ends which gives the central body (1; 1?) a ring-shaped cross-section. The central body (1, 1?) comprises an outer portion (110; 110?), made of trabecular metal material, an inner portion (130; 130?), made of trabecular metal material, and an intermediate portion (120; 120?) made of metal material without significant porosity. The outer portion (110; 110?) and the inner portion (130; 130?) are integrally connected to the intermediate portion (120; 120?). The intermediate portion (120; 120?) is configured to mechanically resist to stresses transmitted to the inner portion (130; 130?) on one side and to the outer portion (110; 110?) on the other side.

An augment system (100) can include a first augment (102) having a superior surface (106) and an inferior surface (108), the superior surface configured for attachment to the underside of the tibial baseplate. The augment system can include a second augment (104) having a superior surface (110) and an inferior surface (112), the superior surface configured for attachment to the inferior surface of the first augment. The first and second augments can be formed of different materials. One or more additional augments can be used with the first and second augments, and the augment system can be stacked on a resected surface of the tibia. In an example, the augment that directly contacts the resected surface of the tibia can be formed of a porous material, such as to facilitate bone growth.

  • Patent number: 9889014
    Abstract: A bone implant, particularly but not necessarily, for fixing bones of the foot is provided having body in the form of a crescent or arced shaped wedge, or a wedge in the shape of a crescent or arc. The crescent shaped wedge has bone screw bores that are each configured to hold a bone screw at a particular angle for receipt in a bone, eliminating the need to also use a plate. The crescent shape provides a graft area that allows introduction and retention of bone graft material to promote bone fusion. One or both tapered sides of the crescent shaped wedge may also have teeth, serrations or the like.

  • Patent number: 9833265
    Abstract: A system for fixating a dysfunctional sacroiliac joint for SI joint fusion, the system including a sacroiliac joint implant, a sacroiliac joint screw or rod and a delivery tool configured for approaching a sacroiliac joint. The system may include an implant having a porous 3D matrix structure and may be manufactured by laser or electron beam additive manufacturing. The delivery tool may include a radiolucent material. The SI fusion system may further include custom sacroiliac joint implants, anchors, alignment tools or targeting arms manufactured for a particular patient. Pre-surgical imaging studies, including 3D rendering, and their interpretation may assist in planning desired trajectories, anchor dimensions and implant dimensions and may provide details specific to the manufacture of particular sacroiliac joint tools or implants and their implantation into the sacroiliac joint. The system may be configured for use with surgical robots and may include an integrated nerve monitoring and stimulation system.

  • Patent number: 9808346
    Abstract: Improved tools and procedures relate to the immobilization of the sacroiliac joint for the treatment of pain associated with the joint. Kits comprise, for example, a guide element and an immobilization element of a biocompatible material with a size and shape suitable for placement within the sacroiliac joint. Suitable immobilization elements include, for example, pins, nails, screws, darts, wedges, shims and hardening material. A bioactive agent can be delivered into the joint to compliment the immobilization and promote healing. Suitable procedures can be done in a less invasive procedure through a cannula or the like.

  • Patent number: 9717598
    Abstract: A prosthetic device for a knee joint includes a body portion and a first keel. The body portion attaches to a bone of a knee joint. The body portion can have a bearing surface configured to replace at least a portion of the bone and an implantation surface configured to face the bone upon implantation. The first keel can be configured to be inserted into a corresponding first keel void formed in the bone. The first feel can be configured to project outwardly from the implantation surface by an amount sufficient to inhibit movement of the body portion relative to the bone in both medial and lateral directions upon insertion into the first keel void. The first keel can extend along a longitudinal direction of the body portion and is offset from a longitudinal centerline of the body portion. Methods of implanting and removing the prosthetic device are also provided.

  • Patent number: 9662216
    Abstract: An implant for a femoral head of a patient. The implant includes a shell implantable on the femoral head of the patient and correcting a defect of the femoral head. The shell is designed preoperatively to have a patient-specific first surface for articulation with the patient's acetabulum and a patient-specific periphery mateable with a periphery of the defect. The shell caps the defect and the first surface of the shell is continuous to a remaining healthy surface of the femoral head. The defect can be a bone defect, a cartilage defect or a combination thereof.

  • Patent number: 9610173
    Abstract: A vertebral body replacement apparatus includes an outer body member having a first end, a second end, and an opening, and an inner body member having a first end, a second end, and an inner surface defining an opening. The first end of the inner body member is received in the opening of the outer body member such that the inner body member and the outer body member are movable relative to one another. A support member has a first end secured within the inner body member and a second end extending a distance beyond the inner body member. The second end of the support member deflects relative to the first end of the outer body member in response to a force applied thereto and returns to a substantially non-deflected condition upon release of the force.
