Intramedullary systems, expandable intramedullary nails, expandable anchors, and methods of using the same. The intramedullary system may include an expandable intramedullary nail configured to extend into an intramedullary canal of a long bone and/or one or more expandable anchors configured to extend at an angle transverse to the intramedullary nail. The intramedullary nails and/or anchors may include one or more integrated expansion mechanisms that allow for insertion in a contracted configuration and expansion into a deployed configuration to lock the relative position and prevent axial rotation and translation of the system.

Systems and methods for restructure and stabilization of bones that provide an anti-microbial effect are disclosed herein. A device includes a delivery catheter having an inner void for passing at least one light sensitive liquid, and an inner lumen; an expandable member releasably engaging the distal end of the delivery catheter; at least one channel positioned in the expandable member; and a light conducting fiber sized to pass through the inner lumen of the delivery catheter and into the expandable member, wherein, when the light conducting fiber is in the at least one channel, the light conducting fiber is able to disperse light energy to provide an anti-microbial effect. When the light conducting fiber is in the expandable member, the light conducting fiber is able to disperse the light energy to initiate hardening of the light sensitive liquid within the expandable member to form a photodynamic implant.

Photodynamic devices for replacement of an articular head of a bone are provided. In an embodiment, a photodynamic device includes a photodynamic support member and an articular member attachable, either fixedly or removably, to the photodynamic support member and having a bearing surface. In an embodiment, the articular member includes a recess designed to receive the photodynamic support member. In an embodiment, the photodynamic support member includes an opening into which a shaft of the articular member can be inserted to attach the articular member to the photodynamic support member.

Intramedullary nails, systems, and methods. The intramedullary nail may include a generally elongate body extending from a first, distal end to a second, proximal end. The distal end may include one or more openings configured to receive one or more bone anchors that extend transversely through the distal end intramedullary nail, and thereby configured to secure the distal end of the nail. The proximal end may also include one or more openings configured to receive one or more bone anchors that extend transversely through the proximal end of the intramedullary nail, and thereby configured to secure the proximal end of the nail. In some embodiments, the proximal end may further include a cross-locking feature, which includes a second bone anchor that interlocks with a first bone anchor, for example, for enhanced bone purchase and bony fixation.

A shoulder implant for simulating a naturally occurring bursa proximal to or in lieu of a subacromial bursa, the shoulder implant comprising: an expandable member expandable to a size and/or a shape sufficient to fill a space beneath an acromion and/or a coracoid process of the shoulder, the space defines a filled volume less than a maximal volume occupied by the expandable member if fully expanded; and an amount of filler for filling the expandable member to the filled volume, such that, when implanted, the expandable member is configured to cushion and facilitate motion between a tendon and/or ligament of a rotator cuff, and a bone part in the shoulder.

Apparatus and methods for treatment of a bone. The apparatus may include an implant. The implant may include an implant tail and an implant head configured to expand, inside the bone, from a collapsed state to an expanded state. The apparatus may include an intramedullary rod defining a central longitudinal rod axis. The intramedullary rod may include a guide segment configured to guide the implant head into the bone and support the implant tail. The intramedullary rod may include an elongated extension member spaced radially apart from the central longitudinal axis. The extension member may be configured to provide clearance for the implant head as the implant head is advanced, in the collapsed state, into the bone. The extension member may be configured to provide clearance for the implant head in the expanded state.
