Coplana X-ray guided aiming arm for locking of intramedullary nails

A novel coplanar X-ray guided method and device for insertion of distal locking screws in intramedullary bone nails. The device has coplanar holes, which allow insertion of protective sleeves. A drill and bone screws can be inserted through the protective sleeves. Radiopaque target markers in the aiming arm enable the easy positioning of an X-ray source such that an X-ray beam is coplanar with the aiming arm transverse holes. After the X-ray source is accurately oriented, a single X-ray snapshot is enough to assess the exact distortion of the implanted intramedullary nail. The X-ray beam need not be coaxial with the intramedullary nail holes. The aiming arm has a mobile portion and a fixed portion fastened to the nail, wherein said aiming arm can be adjusted, displacing the mobile portion over the fixed portion, to compensate for the distortion of the intramedullary nail after implantation. Once the aiming arm is precisely positioned, the aiming arm transverse holes and intramedullary nail holes are accurately aligned, protective sleeves are inserted through aiming arm holes, bone drills are drilled through the intramedullary nail holes and surrounding bone material, and bone screws are inserted, locking the intramedullary nail to the bone.

External Fixator, Kit Comprising the Same, and Method of Fixation
20250082367 · 2025-03-13 ·

The present invention provides an external fixator (1) for fixation of a joint, such as a proximal interphalangeal (PIP) joint of a finger, and a kit comprising a congruent pair of such external fixators (1). The external fixator (1) comprises a rigid planar member made of a radio-transparent material. The planar member comprises a circular through hole (6) and a rectilinear main slot (10), which is radially aligned with the through hole (6). The external fixator (1) may also comprise a circular arc (8) of radio-opaque material centred on the through hole (6), a tail (14) to aid in its manipulation, and one or more subsidiary slots (20). The main and subsidiary slots (10, 20) have dentilated inner surfaces. In addition to a congruent pair of external fixators (1), the kit may further comprise a plurality of Kirschner wires and one or more stoppers (not shown). In use, the pair of external fixators are placed transversely on each lateral side of a patient's finger, a first one of the Kirschner wires is inserted through the through holes (6) in each external fixator (1) and through the condyle or head of the proximal phalanx. A second one of the Kirschner wires is inserted through the main slot (10) in each external fixator (1) and through the middle phalanx. The third Kirschner wire is inserted through a convenient one of the subsidiary slots (20) in each external fixator (1) and through, over or under the middle phalanx or a fragment thereof. Movement of the second Kirschner wire along the main slots (10) in the direction of arrow D can be used to apply a distraction force to the joint. Movement of the third Kirschner wire along the one of the subsidiary slots (20) towards the main slot (10) can be used to reduce subluxation of the middle phalanx or a fragment thereof. The one or more stoppers, which engage with the dentilated inner surfaces of the main and subsidiary slots (10, 20), prevent backwards movement of the Kirschner wires along the main and/or subsidiary slots (10, 20) thereafter. The invention also provides a method which comprises providing a congruent pair of such external fixators (1) for use in a surgical operation.
