摘要:
An implant is provided for use in an ankle joint between reconditioned end surfaces established on a distal end of an upper tibia bone and an opposing lower talus bone. The implant comprises a substantially porous rigid component adapted to be anchored against the upper tibia reconditioned end surface and the lower talus reconditioned end surface. The component defining an opening therethrough. An intramedullary nail is configured to pass through the opening in the component when the nail is driven through the talus and into the tibia.

A prosthetic implant for forming a support structure between adjoining vertebrae in a spinal column. The prosthetic implant includes a generally spherical or ellipsoidal body that at least partially engages a surface of adjacent vertebrae.
摘要:
A mold assembly for the in situ formation of a prosthesis inside an annulus located in an intervertebral disc space between adjacent vertebrae of a patient. The mold assembly includes at least a first mold (54) having at least one interior cavity adapted to be located in the intervertebral disc space. At least a first lumen (52) has a distal end fluidly coupled to the mold at a first location. One or more discrete reinforcing structures are located in the intervertebral disc space with the mold. One or more biomaterials (70) are provided to be delivered to the interior cavity through the first lumen. The at least partially cured biomaterial, the reinforcing structures and the mold cooperating to form the prosthesis.
摘要:
An instrument for controlling the distribution of bone cement on the surface of the head of a bone to prepare the bone to receive a re-surfacing prosthesis comprises a hollow shell which can be fitted on to the head of the bone to define a space around the head. The shell is rotationally symmetrical and has a spike like projection extending axially from the internal surface of the shell. At least one rib is located on the internal surface of the shell, extending from the spike like projection or from close to it, towards the open face of the shell, which contacts cement on the head of the bone in a sweeping action when the shell is rotated around its axis on the head of the bone.
摘要:
A characteristic features of the invention is that a spacer member (1) is intended to be placed between the ends of the bones which are to be connected, one end of the spacer member being designed to form a joint surface against one of said bone ends (6, 7). A joint-stabilizing connection (2, 3) is arranged to connect said ones. The spacer member (1) is made of at least one tissue-compatible material.

An implant for use in spinal surgery comprises a resilient element having an inflatable cavity. It is formed of a biologically compatible material and is arranged for placement between end plates of adjacent vertebra. The implant may also include a wound disc replacement element. A method of performing spinal surgery on a patient comprises securely mounting a patient onto a patient support table; imaging a spinal region of the patient; building up a three-dimensional image file of the spinal region of the patient; storing the image file; and utilizing the image file for planning and carrying out computer controlled spinal surgery on the patient utilizing the implant. A computer-controlled surgical implant system comprises a steerable endosurgical implanting assembly operative to install the implant at a desired location in a patient; and a computerized controlled, which operates the steerable endosurgical implanting system.
摘要:
The invention relates to a three-dimensional hinge (100) comprising a first rigid body (10), a second rigid body (20) and a joint member. The joint member connects the first rigid body (20) and the second rigid body (20). The joint member comprises at least three base connectors (32,33,34), each base connector connected to the second rigid body (20) at respective connection point (22, 23, 24) and engaging with an engaging portion of the first rigid body.

Expandable fabric bags (22) and methods of use for reduction, fixation, support and treatment of bone abnormalities such as tibial plateau fractures, femoral head necrosis, compression fractures of the spine and other bone abnormalities.
摘要:
The invention relates to a dilatable balloon implant (3), which is configured with a limited permeability to liquid. The invention also relates to a vertebroplasty device comprising a balloon implant (3) with a limited permeability to liquid, which is connected to the distal end of an introduction sleeve (2), in such a way that the interior of said implant communicates with the introduction sleeve.
