The adapter can introduce lateral and/or angular offsets between the baseplate and the glenosphere, which can correct for unwanted offsets or inclinations. A middle peg extension (752) can screw onto a medial end of the middle peg (114), which can offer different combinations of peg length and peg material. The baseplates can be made available in various discrete sizes, each of which has the same distance between the middle peg and an inferior screw hole (112).

    Abstract: A glenoid device for preparing a shoulder joint of a patient includes a reusable guide holder having a body between an upper surface and a lower surface and a bore passing through the body of the guide holder. The glenoid device also includes a patient-specific glenoid guide having a body with an upper and lower surface. The lower surface of the patient-specific glenoid guide is configured as a negative surface of a glenoid face based on preoperative image scans of the shoulder joint of the patient. The upper face of the patient-specific glenoid guide is configured to be coupled and contact the lower face of the guide holder, such that the bore of the guide holder is aligned along a patient-specific bore through the body of the patient-specific glenoid guide and along a corresponding alignment axis of the patient-specific glenoid guide.

  • Patent number: 9814588
    Abstract: Arthroplasty components include an articular surface and a bone-facing surface. The bone-facing surface bears at least one anchoring element adapted for an oblique implantation trajectory. The anchoring element includes a reinforcement plate, a dowel, and surface features. Each surface feature resists forces acting along a different direction.

  • Patent number: 9782263
    Abstract: A glenosphere includes a body and a flange. The body includes a first body surface and a spherical second body surface, and includes an engagement feature to engage with an attachment structure attachable to a bone. The flange extends radially outward from the body and includes a first flange surface contiguous with a first body surface and a second flange surface contiguous with the second body surface. The flange has a flange length extending from a first end and a second end such that an angle defined by a first line from a center of the body to the first end and a second line from the center of the body to the second end is less than 180 degrees.

  • Patent number: 9713533
    Abstract: A glenoid implant can include a body, a first fixation member, a second fixation member, and a third fixation member. The body can include an articular surface and a scapula-engaging surface opposite from the articular surface. The first, second and third fixation members can extend from the scapula-engaging surface. The third fixation member can include a porous titanium material and be disposed between the first and second fixation members, such that the first, second and third fixation members define a substantially linear configuration.

  • Patent number: 9687351
    Abstract: A prosthesis including a magnetic implant approximating the size of a bone to be replaced; a first magnetic bone implant securable to a first bone adjacent the bone to be replaced; and a second magnetic bone implant securable to a second bone adjacent the bone to be replaced. Each of the first and second magnetic bone implants have a magnetic relationship with the magnetic implant. A method of reconstructing a wrist includes removing a patient's scaphoid to create a void. The scaphoid has a plurality of adjacent bones, each of the adjacent bones comprising a surface generally facing the void. The surface of at least two of the adjacent bones is prepared by affixing a magnetic element thereto and a magnetic scaphoid implant is inserted into the void. A magnetic relationship exists between the magnetic elements and the magnetic scaphoid implant.

  • Patent number: 9629724
    Abstract: A method of surgically implanting a reverse shoulder orthopedic implant, the method comprises the step of installing a glenosphere component having a bore formed therein over a metaglene component implanted within bone tissue of a glenoid surface of a scapula, capturing a screw cap within the bore of the glenosphere component, the screw cap positioned with a shaft of the screw cap located within a bore formed in an elongated stem of the metaglene component and an upper surface of a locking flange opposite the shaft of the screw cap flush with an upper surface of a platform of the metaglene component opposite the elongated stem of the metaglene component.

  • Patent number: 9629725
    Abstract: Reversed glenoid implants, and related kits and methods, are described that include an anchor member having a proximal head and a baseplate having a distal end with a first aperture sized to accept the proximal head of the anchor member. The proximal head is inserted along an un-threaded length thereof from the distal end into the first aperture, and the anchor member is restrained against axial translation with respect to the baseplate but is permitted to rotate with respect to the baseplate.

  • Patent number: 9610168
    Abstract: A total ankle replacement prosthesis may comprise a tibial implant, a talar implant, and an intermediate implant. The intermediate implant may fixedly attach to the tibial implant and may articulate with respect to the talar implant. The intermediate implant may have unequal front and back angular extent, so as to discourage a particular direction of subluxation, and a kit may be provided containing various such intermediate implants. Various features may be provided in regard to dovetails, fins, recesses, the placement of fins and pegs, and the shape of the perimeter of the tibial implant. Recesses may allow a surgical blade to slice a latch off of an already-installed intermediate implant, in order to allow its removal from the tibial implant.
