The invention relates to an implant for the osteosynthesis of the PIP arthrodesis or the DIP arthrodesis of small joints and for the osteosynthesis and stabilisation of fractures of small bones of the human skeleton, said implant being resorbable by the human body. The implant consists of two shafts placed against each other. At least one fixing aid is located between the shafts, said fixing aid protruding beyond the diameter of the shaft. Each shaft can optionally have longitudinal grooves and transverse grooves. The implant consists of a magnesium-based material which can be resorbed by the human body. The invention provides an implant which has an extremely high tensile strength, excellent stability, optimal healing properties, and an optimally adapted resorption speed.

A photocurable device injection system for creating in situ polymerization via light or free-radical to enable fractured bone fixation. The system comprises a photosensitive polymeric resin sensitive to light, temperature, oxygen, enzymes, or a combination thereof. The photosensitive polymeric resin may be configured to cure at room temperature or physiological temperature with a light source. The photosensitive polymeric resin may be configured to depolymerize with ultrasonication, sonication, or a combination thereof. The system further comprises an implantable 3-dimensional biocompatible pouch comprising an optical light guide. The system further comprises one or more micro-sized ultrasonication probes configured to contact a three-dimensional pouch by one or more openings. The one or more probes may be configured to enable polymer outflow.

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.

A method and a device for bone adjustment in a mammal is presented, wherein a device is implanted in the medullar cavity of a bone in the body of said mammal, said device being a device exerting a force to anchoring devices anchored ins aid bone. The method and device has utility in therapeutic and cosmetic bone adjustments, including the lengthening, reshaping and realigning of bones, for example in the correction of congenital deformations, restorative orthopedic surgery and the like.

A method for the long-term delivery of fluids to a bone of a patient includes providing a cannulated bone screw and an insert configured to be coupled to the bone screw. The method further includes creating an aperture in the skin of a patient, inserting the bone screw into a bone of the patient through the aperture, and coupling the insert to the bone screw. The method further includes the steps of providing a fluid source, coupling the fluid source to the insert, and delivering a fluid from the fluid source to the insert.

The present invention provides a system for fixation of fractures comprising an orthopedic plate configured to abut and support the side of a bone. A cupped drill guide cooperates with the end of the plate and envelops a portion of the bone with a hook and drill guide assembly that can be used to reduce that bone. An expandable cage member can be inserted through the plate into the bone to buttress it, to inhibit subsidence, and to cause or to support the reduction. Optionally the cage member holes can be used for a smaller diameter screw through the use of inserts.

The disclosure provides example methods, systems and apparatus for stabilization of a rib. An example method includes: (a) accessing a medullary canal of a rib having a fracture, (b) advancing a guidewire into the medullary canal across the fracture, (c) advancing a delivery catheter containing a stent over the guidewire into the medullary canal and across the fracture, (d) retracting the delivery catheter relative to the stent, and (e) expanding the stent in the medullary canal.

One aspect of the disclosure relates to an aspect of the disclosure relates to an adjustable implant including: a housing; a first adjustable member at least partially positioned within the housing and moveable relative to the housing; and a first actuation assembly positioned within the first adjustable member and configured to move the first adjustable member relative to the housing.

An implant and method for fixation of long bones. The implant provides rotational, longitudinal, and bending stability. The implant comprises one or more elongated members that span the intramedullary cavity of a long bone, a distal tip that expands radially relative to the long axis of the implant, and a locking mechanism at the proximal end of the implant.

Orthopedic fastener devices for fixation of fractured bones are disclosed. The orthopedic fastener device is in the form of an orthopedic fastener having an IM nail coated on its external surface with a bioabsorbable or biodegradable hydrogel. Also disclosed are hydrogel coated orthopedic fastener devices in the form of a K-wire or bone screw, a method for stabilizing a fractured long bone fracture by inserting an orthopedic fastener into the medullary canal of the bone and a kit for fastener implantation.
