摘要:
An orthopaedic implant system includes an orthopaedic implant implantable at a selected location within a corporeal body. The implant includes a first structural material and a second structural material. The first structural material is non-resorbable relative to the corporeal body and is different relative to the second structural material. The implant is an internal fixation device.

The present invention extends to a stemmed amputation implant. In some embodiments, a dual stemmed implant includes a base plate and two intramedullary rods extending from the proximal side of the base plate. The two intramedullary rods are configured for insertion into corresponding intramedullary bone canals reamed into remaining portions of amputated bones, such as, for example, a tibia and fibula or an ulna and radius. The position of the intramedullary rods relative to one another is configured to maintain appropriate separation between amputated bones when the first intramedullary rod and the second intramedullary rod are inserted into the amputated bones. In some embodiments, a hollow tube replaces one or more of the intramedullary rods. A hollow tube can be configured to cover the exterior of a bone, such as, for example, the fibula, when the bone is not stable enough for intramedullary fixation.

An implant is provided which enhances structural stability across a joint between a first and a second bone to be immobilized. The implant comprises a first and a second element, wherein the first element comprises a proximal, a distal and an intermediate section. The front end of the implant is formed as a pointed head with structures enabling the implant to penetrate bone material, including a channel-like structure running from the front end to a reservoir in the intermediate section. The reservoir is provided for receiving bone material through the channel-like structure and distributing it into a space between two bones upon placing the implant into the bones. A tool is provided for placing the implant into two bones, wherein the tool has means for connecting it to structures in the first element and the second element, so that the two elements can be moved independently.

A fusion device for fusing a joint of a human or animal patient is provided, wherein the joint is a synovial joint comprising two articular surfaces and a gap therebetween, and wherein the device comprises: at least one anchorage portion (1) and at least one stabilization portion (2), wherein the anchorage portion(s) and the stabilization portion(s) constitute separate parts wherein the fusion device has an overall depth (D) parallel to an implantation direction (I), the overall depth extending from a proximal face (4) to a distal end of the fusion device, an overall width (W) and a thickness profile (T1 and T2) perpendicular to the implantation direction (I), wherein the at least one anchorage portion (1) comprises a thermoplastic liquefiable material being arranged on a surface of the anchorage portion (1) or inside a perforated sheath (52) constituting a part of the anchorage portion (1), and wherein the anchorage portions are configured to be positioned and anchored between the articular surfaces in the joint first, and the stabilization portion is capable of being mounted on the proximal ends of the anchorage portions or wherein the stabilization portion is configured to be positioned between the articular surfaces first, and the anchorage portions are capable of being pushed through or past the stabilization portion and anchored in the bone tissue beside and/or beyond the stabilization portion.
摘要:
The sacral-iliac joint between an iliac and a sacrum is fused either by the creation of a lateral insertion path laterally through the ilium, through the sacral-iliac joint, and into the sacrum, or by the creation of a postero-lateral insertion path entering from a posterior iliac spine of an ilium, angling through the sacral-iliac joint, and terminating in the sacral alae. A bone fixation implant is inserted through the insertion path and anchored in the interior region of the sacrum or sacral alae to fixate the sacral-iliac joint.
摘要:
According to some embodiments, systems and methods for reshaping bone are provided. The systems may include an implant body, an actuator coupled to the implant body, a sensor configured to detect a parameter indicative of a biological condition, a transceiver, and a controller. The transceiver may be configured to transmit data associated with the parameter to an external remote control and receive instructions from the external remote control. Finally, the controller is configured to move the actuator in response to the instructions from the external remote control, wherein the actuator adjusts the implant body. The methods may include measuring a parameter indicative of a biological condition; transmitting data associated with the parameter from the implantable device to an external remote control; transmitting instructions from the external remote control to the implantable device; and actuating the bone growth device in response to the instructions from the external remote control.
