The disclosure generally relates to condylar implant assemblies and methods for inserting an implant assembly for supporting the condylar head of a bone. More particularly the disclosure relates to an implant assembly for use in support of the condyle of a humerus, femur, or other bones having a condyle comprising spongy bone. In some implementations, the implant assembly may be inserted into the head of the bone and bands of a dilating member of the implant assembly may be expanded through slots in a tube of the implant assembly for supporting the condylar head of the bone.

A method for bone healing or treatment of bone fracture in a subject includes optionally pre-drilling a hole or creating a cavity in a body tissue, implanting a device onto or into the body tissue, or at least partially inserting a device into the cavity or hole, administering a composition into the device and/or near the device. The composition includes a first finely divided particulate material, and can optionally include at least a second material. The first material is not bioresorbable or is very slowly bioresorbable and the second material or materials are bioresorbable at a higher rate than the first material. The method can optionally include fully inserting the device into the hole or cavity, and can optionally include administering a pharmaceutical composition to the subject.

The current invention features a rod screw for medical application that can be configured and used to fixate fracture of bones varying in shape and dimension, and treating maladies such as scoliosis, and securing an implanted device, to tissue such as bone. This is achieved by designing a flexible rod screw with a mechanism to lock the configuration in a rigid state. In an embodiment, a bone-fracture fixation device, such as a rod screw, includes a flexible body, a plurality of flexible members, and first and second interfaces. The flexible members are disposed longitudinally within the flexible body, such that the flexible body is rigid when the flexible members are fixed into position. And the first and second interfaces are respectively coupled to the flexible body, each of at least one of the first and second interfaces including a respective at least one hole each configured to receive a respective attachment member configured to engage a bone.

A bone implant includes a bore extending entirely through the bone implant. The bone implant also includes a light source to emit light onto bone adjacent the bone implant to stimulate bone growth and/or reduce bone loss.

The invention features bone drill guides, sleeves, and methods of use thereof in inserting hardware into bones, in particular to repair bone defects. The bone drill guides are designed to seat firmly against bone while allowing translational, rotational, and angular movement during an operation. The bone drill guides also allow for insertion of multiple devices, such as guide wires, into bone at defined and constrained relative position.

A bone fixation device for treatment of a bone fracture includes a fixation screw defining a transverse opening, a fixation arm configured for inserting the fixation screw through a bone fracture, a set screw, and an aiming arm configured for inserting the set screw into the transverse opening and engagement with the fixation screw. The set screw stabilizes the fixation screw.

A fracture fixation system includes a barrel extending along a barrel axis from a proximal end to a distal end having a peripheral wall. The barrel defines a passage through the barrel that extends along the barrel axis. The peripheral wall defines a transverse bore passing through opposing sides of the peripheral wall at the proximal end of the barrel in a direction that is substantially transverse to the barrel axis. The fixation system includes a peg extending along a peg axis and configured for insertion into the passage. The fixation system includes a flange configured for insertion into the transverse bore of the peripheral wall.

A smart medical device includes a structure configured to be at least partially implanted in a body, and an electronics cartridge that is configured to be inserted into the structure after the structure is implanted in the body. The structure may be a cannulated screw for use in treating bone fractures. The medical device includes an impedance sensor for monitoring and reporting on the healing state of bone fractures. The sensor includes components of the electronics cartridge and electrodes that are either associated with the cannulated screw or with the insertable electronics cartridge.

A method of reinforcing a femoral neck comprises creating a bore proximate to at least one of a Ward's triangle and a greater trochanter, creating at least one cavity in a cancellous bone region of the femoral neck, inserting a substantially collapsed support structure through the bore and into the at least one cavity, expanding the support structure, and allowing at least a portion of the load from the femoral neck bone to be transferred to the support structure. The support structure compresses at least a portion of the cancellous bone upon expansion. A cavity created by the expansion is adapted to receive a filler material such as, but not limited to, bone cement.

A bone plate for treating periprosthetic fractures includes a head portion to be positioned along a greater trochanter of a bone. The head portion includes pairs of bone fixation element receiving openings extending therethrough from a first surface of the plate which, when the plate is in an operative position, faces away from the bone, and a second surface which, when the plate is in the operative position, faces toward the bone. A pair of cable holes extend through the head portion from a first longitudinal side connecting the first and second surfaces to a second longitudinal side connecting the first and second surfaces. The head portion includes a pair of hooks for engaging a superior ridge of the greater trochanter. The plate also includes a shaft portion extending distally from the head portion to extend along a portion of the bone distal of the greater trochanter.
