An intramedullary nail for a fractured elongated bone, comprising a cannulated rod having proximal and distal ends; an outside tubular sleeve for coaxially hosting and guiding the rod; and at least a pair of shape memory elements hosted in corresponding seats at the distal end of the rod. Each shape memory element can be retractably housed in its seat in a first configuration, allowing insertion of the nail into the bone, and can project from a sleeve opening in another configuration. Pairs of transversal holes are provided in proximal portions of the rod and the sleeve. The distal pair of shape memory elements lie on an offset plane to the plane of the proximal holes and are kept in their corresponding seats by a distal cover fixed to the rod. This improves the stability of the nail in the medullary canal.

Intramedullary nail with shape memory elements for elongated bones

An intramedullary nail for a fractured elongated bone, comprising a cannulated rod having proximal and distal ends; an outside tubular sleeve for coaxially hosting and guiding the rod; and shape memory elements hosted in corresponding seats of the rod. Each shape memory element can be retractably housed in its respective seat in a first configuration, allowing insertion of the nail into the bone, and can project from a sleeve opening in another configuration. Proximal and distal pairs of the elements are provided at the proximal and distal rod ends. The proximal element pair lie on a same plane and are kept in their seats by a proximal cover. The distal element pair lie on an offset plane to the plane of the proximal element pair and are kept in their seats by a distal cover. This removes the need for bone screws to stabilize the nail inside the medullary canal.

Intramedullary nail with shape memory elements

A device for use in the treatment of proximal humerus fractures, having a substantially spoon-shaped body comprising a blade-like proximal portion provided with at least one seat, a plate-like and elongate distal portion provided with at least one seat, a central bulge, or block, including a central seat, the central bulge interposed between the proximal portion and the distal portion, a cylindrical counterbore obtained in the central bulge and communicating with the central seat, and an eccentric ring and annular seat, the eccentric ring positioned within the annular seat.

Device for the ostheosynthesis of proximal humerus fractures

An intramedullary nail () suitable for insertion in a fractured elongate bone (), of the type comprising a stem () extended between a proximal end () and a distal end (). The nail comprises a plurality of elements () realized with at least one shape-memory material, a plurality of seats () formed in the stem () for housing the elements (). The elements () are suitable to take a first shape wherein they are retractably housed in the respective seats () and a second shape wherein they project from the respective seats ().

Intramedullary nail comprising elements of shape-memory material

A device for use in the treatment of proximal humerus fractures, comprising a substantially spoon-shaped body having a blade-like proximal portion intended to complement the humerus head and provided with at least one seat in which to insert a wire, a threaded nail, or a similar element to stabilize the fracture, a plate-like and elongate distal portion, intended to complement the humerus neck and provided with at least one seat in which to insert a screw or a similar element to fix the body to the humerus, and a central bulge, or block, interposed between the proximal portion and the distal portion and wherein a seat is obtained in which to insert a screw intended to stabilize the humerus head.

An endomedullary nail for the treatment of proximal femur fractures, comprising an elongate body () having a proximal portion () and a distal portion (). The proximal portion () has a first and a second hole () for a respective cephalic screw (), each having a transversal axis to the axis of the proximal portion (). The first hole () is split into two passages each having a respective axis (A, B) with a predetermined angle relationship with respect to the axis (C) of the second hole (). The passages () are arranged to be selectively engaged by a respective cephalic screw ().

External fixation device for reducing bone fractures

The invention relates to a new type of axial unilateral external splint device for stabilizing bone fractures, comprising an extendible rod-like middle body () and oppositely located bone screw clamps () which are articulated to respective ends () of the rod-like middle body () by means of ball joints. Advantageously, a ball-and-socket joint () is mounted to each clamp (), within a main body () with which a bone screw clamping arrangement () is associated or co-operates. Also provided are ancillary members () adapted for removable association with the end of each clamp () to allow each clamp to be more suitable for use, depending on the different operative installation conditions of the fixator.

Axial external fixator

The invention relates to a bone screw, particularly for use with external splints in fracture stabilization, comprising an elongate cylindrical body ( ) of predetermined length and diameter tapering into a threaded end portion ( ) which terminates with a tip ( ), and an opposite screw-handling end ( ). The screw-handling end ( ) has substantially the same diameter as that of the elongate cylindrical body ( ) and comprises a flat ( ) extending parallel to the axis of the cylindrical body over the main part of the cylinder body portion unoccupied by the thread. In a further embodiment, the screw-handling end ( ) is formed with a plurality of flats ( ) extending parallel to the axis of the cylinder body ( ) at predetermined spacings. These flats extend over the main part of the cylindrical body portion unoccupied by the threadway and alternate with lands ( ).
