摘要:
The invention relates to a device (17) for tensioning a flexible band (3) used to maintain a bone element on an implant, said device comprising a rod (18) having a first end (19) provided with means (20) for bearing on the implant, a movable part (32) for hooking the flexible band onto a portion (28) of the device, and means (34) for adjustably locking the movable part in translation in relation to the portion of the device. The rod (18) comprises a gripping handle (26) at the second end (27) thereof. The aforementioned portion of the device forms an angle α with the rod (18) to which it is rigidly connected at an intermediary point, the direction of the band being altered at an angle, and the aforementioned adjustable locking means (34) comprise manual screwing means (35) for actuating the movable part.

The present invention provides an intervertebral fusion apparatus for positioning and combining vertebrae, which uses a solidifiable material and an intervertebral fusion cage concurrently. By diffusing the solidifiable material from the top or bottom surface of the intervertebral fusion cage, the contact area with vertebrae and hence the stability can be increased. In addition, the intervertebral fusion cage provided by the present invention can further include a wing member connected pivotally on the side and operated concurrently with the solidifiable material to change the shape and thus avoid slipping off the operation opening. By using the intervertebral fusion apparatus, the stability of the intervertebral fusion cage during and after surgeries can be improved effectively. Thereby, the success rate and safety of vertebral fusion surgeries can be increased.

The invention concerns a set of femoral stems comprising a stem (1) designed to be impacted in a bone cavity with cement and a stem (2) designed to be impacted in said cavity without cement. The invention is characterized in that the cross-section of each of the stems (1) and (2) is different and determined to enable their being set after passing a single file which is identical in dimension to the cement-free stem (2) whereof the cross-section is determined to ensure immediate self-locking following impingement; the stem (1) designed to be impacted with cement, is self-centered in the metaphyseal part through a portion at the cervical section identical in front and saggital dimensions to the file and centered in the metaphyseal part by a closure plug (3), said stem (1) including a central through channel (1a) for injecting the cement and its discharge outside to fill the space between the stem and the bone.
摘要:
An apparatus for forming a flowable material against a prosthetic implant can comprise a mold body having an outer surface and an inner surface. The inner surface can define a mold cavity that is selectively configured to at least partially accept the prosthetic implant in a forming position. An inlet port can be configured on the mold cavity that extends between the inner and outer surfaces. The mold cavity can substantially conform to a profile of a bone opposing surface of the prosthetic implant such that a void is created between the inner surface of the mold body and the bone opposing surface of the prosthetic implant. The inlet port can be configured to permit introduction of the flowable material into the void and against the bone opposing surface of the prosthetic implant

摘要:
Methods and apparatuses for restoration of human or animal bone anatomy, which may include introduction, into a bone of an expansible implant capable of expansion in a single determined plane, positioning the expansible implant in the bone in order to correspond the single determined plane with a bone restoration plane and opening out the expansible implant in the bone restoration plane. A first support surface and a second support surface spread tissues within bone. The embodiments of the disclosure may also include injecting a filling material around the implant.
