55 results about "Second tarsal bone" patented technology

The calcaneus (heel bone) is the largest of the tarsal bones. It transmits the weight of the body to the ground and acts as a lever for the muscles of the calf. The calcaneus joins with the talus and cuboid. The talus (ankle bone) is the second largest of the tarsal bones and sits atop the calcaneus.

Apparatus and method for stabilizing adjacent bone portions

A method and apparatus for stabilizing first and second adjacent bone portions. The method includes the steps of: providing a spacer; providing a stabilizer, with the spacer and stabilizer configured to be movable guidingly, one relative to the other, between a pre-assembly relationship and an operative relationship; and placing the spacer and stabilizer into an operative relationship with the first and second adjacent bone portions. As an incident of the spacer and stabilizer being changed from their pre-assembly relationship into the operative relationship with each other and the first and second bone portions, the spacer, stabilizer and first bone portion cooperate to cause the first bone portion and spacer to be urged towards each other. The method may be carried out by moving the stabilizer and spacer, and all auxiliary parts and handling and assembling instruments, substantially in a single plane along one line or parallel lines.

Ligament reestablishing system

The invention relates to the field of medical instruments and discloses a ligament reestablishing system. After a ligament is reestablished for the first time by using the ligament reestablishing system, the ligament can be quickly replaced through a small incision outside a joint without using an arthroscope if a revision surgery needs to be carried out on the ligament. Because the technology has the character of quick revision, a ligament substitute material is not needed to be firmly combined with a bone channel any longer, so the ligament reestablishing system provides possibilities for reliable use of artificial materials except autologous / allogenic tendons. Moreover, the difficulty and cost of the revision surgery are reduced, the hospital time is reduced, and the indication of ligament reestablishment is expanded. The ligament reestablishing system comprises a first endosteal hollow channel, a second endosteal hollow channel, a ligament substitute, a first fixing piece and a second fixing piece. A bone penetrating through the near end of the joint and a bone penetrating through the far end of the joint are implanted into the first endosteal hollow channel and the second endosteal hollow channel respectively. The ligament substitute is placed into the first endosteal hollow channel and the second endosteal hollow channel.
