Abstract

An arthroscopic surgery method for ankle impingement of the embodiment removes a posterior process of talus from the portal formed in the position specified beforehand by vibrating ultrasonically of an ultrasonic treatment tool which inserted and inserted the ultrasonic treatment tool to the posterior process of talus and a tendon sheath of flexor hallucis longus muscle tendon, and deletes the tendon sheath of flexor hallucis longus muscle tendon by the ultrasonic treatment tool used for deleting the posterior process of talus.

First claim

What is claimed is:

1. An arthroscopic surgery method for ankle impingement comprising:
inserting an ultrasonic treatment tool into a portal formed in a position specified in advance such that a tip of a probe of the ultrasonic treatment tool reaches a posterior process of a talus and a tendon sheath of a flexor hallucis longus muscle tendon to be treated;
removing the posterior process of the talus using the tip of the probe that is vibrating ultrasonically to knock the posterior process of the talus and pulverize the posterior process of the talus into extremely fine pieces; and
excising a fibrous tendon sheath of the tendon sheath of the flexor hallucis longus muscle tendon and canceling strangulation of the tendon sheath of the flexor hallucis longus muscle tendon by shaving the posterior process of the talus using an ultrasonic vibration of the ultrasonic treatment tool.

2. The arthroscopic surgery method for ankle impingement according to claim 1 , wherein the portal is a rear portal.

3. The arthroscopic surgery method for ankle impingement according to claim 1 , wherein the portal is a front portal.

4. The arthroscopic surgery method for ankle impingement according to claim 1 , wherein
the portal forms a front portal and a rear portal and
when the portal is the front portal, the method for the front portal is subsequently performed after the rear portal.

5. An arthroscopic surgery method for ankle impingement comprising:
positioning an ultrasonic treatment tool such that a tip of a probe of the ultrasonic treatment tool reaches an osteophyte on an inner side of a talus and/or a tibia;
shaving a synovial membrane using the probe vibrating ultrasonically; and
removing an osteophyte using the tip of the probe that is vibrating ultrasonically to knock the osteophyte and pulverize the osteophyte into extremely fine pieces.

6. The arthroscopic surgery method for ankle impingement according to claim 5 , wherein the osteophyte is an osteophyte of a lower end front of the tibia and an osteophyte of a neck of the talus.

7. An arthroscopic surgery method for ankle impingement performed under an arthroscope comprising:
a first surgical step of inserting an ultrasonic treatment tool and the arthroscope into a joint fissure between a talus and a tibia through at least two portals;
a second surgical step of circulating a perfusion around a location to be treated;
a third surgical step of removing a synovial membrane/soft tissue;
a fourth surgical step of securing a field of view by cutting and eliminating a tissue and a ligament determined to be excess;
a fifth surgical step of excising a lateral tubercle of a posterior process of the talus;
a sixth surgical step of dissecting a tendon sheath of a flexor hallucis longus muscle tendon and canceling strangulation;
a seventh surgical step of removing a pathologic soft tissue of anterior impingement; and
an eighth surgical step of removing an osteophyte of the tibia and the talus, wherein
a probe of the ultrasonic treatment tool that is vibrating ultrasonically is used for each procedure of at least the third surgical step to the eighth surgical step, and
in the eighth surgical step, the osteophyte of the tibia and the talus is knocked and pulverized by a tip of the probe into extremely fine pieces to remove the osteophyte of the tibia and the talus.

8. The arthroscopic surgery method for ankle impingement according to claim 7 , wherein
nerves, blood vessels, and ligaments present close to and around the location to be treated are not damaged while performing the third through eighth surgical steps.
