Publication number: 20120263683Abstract: Provided herein are preparations for repairing enchondral or osteochondral defects (4) by implantation, said preparations comprising a cartilage element (A) and optionally a bone element (B) which is connected to the cartilage element (A). The cartilage element (A) can contain cells during the implantation or is populated after the implantation with cells migrating from surrounding tissue. The aim is to better equip the cartilage element (A) of one such preparation for integration into the surrounding tissue and/or for an easy-to-achieve, primary stability. To this end, said cartilage element is not homogeneously embodied but has different characteristics in a peripheral and/or basal region (2, 3) to those in a central region (3). Said differing characteristics (A) relate to the structure and/or composition of the matrix used and/or to the cells established in the matrix, and are not used to prevent the migration of cells into the preparation from the surrounding tissue.Type: ApplicationFiled: April 16, 2012Publication date: October 18, 2012Applicant: Zimmer Orthobiologics, Inc.Inventors: Simona Berardi Vilei, Peter Bittmann, Philipp Wagner, Martin Frenz

Patent number: 8287546Abstract: Embodiments disclosed herein provide a combination compressor/distractor useful for fitting a spinal stabilization system in a patient through minimally invasive surgery. The spinal stabilization system may comprise screws anchored in vertebrae. The vertebrae may need to be compressed or distracted. One embodiment of an instrument disclosed herein may comprise a shaft for engaging one of the screws through an extender sleeve. A driver may engage another screw through an opening of the instrument. Through this engagement, a surgeon may use the rack and pinion of the instrument to compress or distract one or more levels of the vertebrae in a parallel motion, which can be advantageous clinically in certain situations.Type: GrantFiled: June 5, 2009Date of Patent: October 16, 2012Assignee: Zimmer Spine, Inc.Inventors: Emily E.

Publication number: 20120253469Abstract: A surgical instrument is disclosed that facilitates the implantation of one of a number of differently sized or differently configured hip stem prostheses into a proximal end of a femur while also providing a surgeon with a substantial amount of rotational control over the prosthesis during the implantation. A suitable hip stem prosthesis is selected from a family of hip stem prostheses of varying sizes and dimensions. The surgical instrument attaches to the selected hip stem prosthesis via first and second spaced engagement portions such that the instrument is operable to exert rotational control over the selected hip stem prosthesis. The first engagement portion is an impaction portion configured to engage a corresponding impaction feature on a proximal body portion of the hip stem prosthesis. The second engagement portion is an adjustable clamping portion configured to clampingly receive the neck of the hip stem prosthesis, regardless of the prosthesis size.Type: ApplicationFiled: June 30, 2011Publication date: October 4, 2012Applicant: ZIMMER, INC.Inventor: James S.

Patent number: RE43714Abstract: Repairs of cartilage defects or of cartilage/bone defects in human or animal joints with the help of devices including a bone part (1), a cartilage layer (2) and a subchondral bone plate (4) or an imitation of such a plate in the transition region between the cartilage layer (2) and the bone part (1). After implantation, the bone part (4) is resorbed and is replaced by reparative tissue only after being essentially totally resorbed. In a critical phase of the healing process, a mechanically inferior cyst is located in the place of the implanted bone part (1). In order to prevent the cartilage layer (2) from sinking into the cyst space during this critical phase of the healing process the device has a top part (11).Type: GrantFiled: December 12, 2000Date of Patent: October 2, 2012Assignee: Zimmer Orthobiologics, Inc.Inventors: Daniel Nadler, Pedro Bittmann, Margarete K.
