Prosthesis for hip replacement with polyethylene head and anti-rotational intra-prosthetic assembly
11638647 · 2023-05-02 ·

This invention corresponds to a prosthesis for total or hip resurfacing replacement, which comprises a prosthetic femoral head made of highly cross-linked polyethylene, with a diameter ranging from 38 mm to 64 mm, to articulate with a cup or acetabular component made of metal. When the invention applies to total hip replacement, the polyethylene head includes a metal core, which contains inside the female counterpart (14) to mate with the male counterpart (13) of a Morse taper, located at the upper end of the femoral component. The use of this type of head for total hip replacement, articulated with an ultra-polished acetabular cup, reduces the risk of dislocation, transmits less angular and torque forces to the Morse taper than large metal heads, and avoids the problems related to the metal-metal bearing or with the use of large metal heads with thin polyethylene. When the invention relates to hip resurfacing replacement, the highly cross-linked polyethylene femoral head has a lower polyethylene extension or stem with or without internal metal reinforcement (151) or a metal stem integrated into a metal-back (152). Using these types of heads for hip resurfacing replacement heads eliminates the problems associated with metal-on-metal resurfacing replacements.

GLENOID AUGMENTATION USING SOFT TISSUE GRAFT
20230139844 · 2023-05-04 ·

Surgical constructs, assemblies, kits and methods of tissue fixation are disclosed. Glenoid augmentation is conducted with one or more soft tissue grafts placed on the anterior glenoid to fill a glenoid defect. Knotted or knotless suture anchors can deliver and fixate the soft tissue graft within the glenoid bone defect. Suture anchors can also secure the native ligament to the soft tissue graft and provide stability to the shoulder joint. Soft suture anchors can deliver and fixate a soft tissue graft within the bone defect. The native soft tissue can be repaired over top of the soft tissue graft into its anatomical position.
