Problems solved by technology

[0005] A problem common to all of these systems is that once the implant has been implanted and without additional surgery, it is difficult to adjust the implant to, for example, maintain a compressive force to support the healing process

Embodiment Construction

[0097] Usually, see Figures 1 to 10D , an implant system constructed according to one embodiment includes one or more implant assemblies 1 and an instrument 50 configured to implant the implant assemblies 1 in a patient. Each implant assembly 1 can comprise a first implant component, which can be in the form of a first plate 10, a second implant component, and a retractable element 5, the second implant component It may be in the form of a second plate 30, the retractable elements being connected to the first plate 10 and the second plate 30, respectively. In use, the first plate 10 can be deployed relative to a first portion of musculoskeletal tissue (eg, first bone portion 12 ), while the second plate 30 can be deployed relative to a second portion of musculoskeletal tissue (eg, second bone portion 12 ). Section 11) while deploying. The first bone part 12 may be, for example, the ilium of the right hip and the second bone part 11 may be the ilium of the left hip.

Abstract

The invention discloses an implant assembly comprising a first implant component, a second implant component, and a retractable element connected to the first implant member and said second implant member. The first implant component is configured for placement against a first bone portion, and the second implant component is configured for placement against a second bone portion. The retractable element is secured to one of the first implant member and the second implant member at a first end and is implanted relative to the first implant at a second end. One of the implant member and the second implant member is movable to induce tensioning of the suture to apply a compressive force on the first bone portion and the second bone portion. Subsequently, the second end may be fixed relative to the first implant component and the second implant component. The length of the contractile element is contractible in response to bodily fluids, thereby ensuring adequate post-operative compression. The present invention also discloses an instrument configured to respectively implant the first implant component and the second implant component in the first bone portion and the second bone portion Adjacent location.

Description

technical field [0001] The present disclosure relates to implants, devices, methods of implantation, and methods of manufacture. Background technique [0002] Implants for holding parts of bone together to support bone healing are known. For example, Figure 11 Examples of conventional implants are shown. Commercially available from DePuy Synthes with a place of business in West Chester, PA ® The implant is used to hold the fractured part of the sacrum together. The implant may include one or more rod assemblies 200, each rod assembly 200 having a rod 201 extending through the opposite first portion 12 and second portion 11 of the ilium, respectively, the rod assembly 200 positioned on the opposite side of the sacrum S Inner-outer. The rod may be threaded and configured to threadably receive respective first and second nuts 202, 204 at opposing first and second ends thereof. A first nut 202 and a second nut 204 can be threadedly connected to the rod 201 and pressed agai...
