摘要：
device and method for treating a human or animal joint. The present invention relates to a human or animal joint which is treated by introducing a device between suitably prepared joint joint surfaces in which the device is anchored to both of these joint surfaces with the aid of a device. material that has thermoplastic properties and with the help of vibratory energy. to allow at least limited joint pivoting after deployment, the device comprising two pivot portions (1 and 2), wherein one of the pivot portions is anchored to each of the joint pivot surfaces. In implantation a proximal face of the device is contacted with a vibrating tool (5) and vibration is transmitted through parts of the device to locations in which the material having thermoplastic properties is close to the bone tissue other than the joint pivot surfaces and in which liquefaction is desired. The liquefied material penetrates the bone tissue and on resolidification forms a positive fit connection between the device and the bone tissue. In order to achieve objective and efficient liquefaction, as little energy loss as possible, and yet allow the articulation of the articulating portions (1 and 2) of the device relative to each other after implantation, the device is equipped at least for implantation. , with a temporal connector portion (4) connecting the two pivot portions (1 and 2) to form joints with the connector portion (4) and possibly an interface portion (3), a rigid item. the connector portion (4) is removed from the joint immediately after anchoring of the joint portions (1 and 2) or in a second surgical operation after a healing phase in which the joint is immobilized by the connector portion or the connector portion (4). ) consists of a bioabsorbable or biodegradable material and is gradually removed by bioabsorption or biodegradation.dispositivo e método para tratar uma junta humana ou animal. a presente invenção refere-se a uma junta humana ou animal que é tratada por meio de intr
