Human or animal joints are treated by introducing a device that anchors on both joint surfaces with the aid of thermoplastic material and vibrational energy between the joint surfaces of appropriately prepared joints. After implantation, the device includes two joints (1,2) anchored at each articulating surface of the joint so that the joint can perform at least a limited joint motion. At the time of implantation, the proximal side of the device contacts the vibrating tool 5 and the vibration is transmitted through the elements of the device to the bone tissue of the joint surface of the joint and the liquefaction is delivered to the desired location. The liquefied material penetrates the bone tissue and solidifies again to form a firm, customized connection between the device and the bone tissue. To achieve the desired effective liquefaction, where possible, to reduce the energy loss, and to allow the joints (1,2) of the device after implantation to perform joint movements with each other, the device comprises at least two joints And a temporary connection portion 4, and is provided with a connection portion 4 and a boundary portion 3 which is a solid element, if possible. The connection part 4 is removed from the joint immediately after the anchor of the joint part 1 or 2 or is removed in the second operation step after the healing step in which the joint is fixed by the joint part, or the connection part 4 is made of a bioabsorbable or biodegradable material And is slowly removed by bio-absorption or biodegradation.인간 또는 동물 관절은 적절하게 준비된 관절의 관절면 사이에 열가소성 물질과 진동 에너지의 도움으로 양 관절면에 앵커되는 장치를 도입하여 치료된다. 이식 후, 관절이 적어도 제한적인 관절 운동을 할 수 있도록, 장치는 관절의 관절면마다 앵커되는 두 관절부(1,2)를 포함한다. 이식 시, 장치의 근위면은 진동 도구(5)와 접촉하고 진동은 장치의 요소를 통해 열가소성 물질이 관절의 관절면의 골조직에 인접하고 액화가 바람직한 위치에 전달된다. 액화된 물질은 골조직에 침투하고 다시 고화되면 장치와 골조직 사이에 확고한 맞춤 연결을 형성한다. 가능하면 에너지 손실을 줄이면서 목적하는 효과적인 액화를 달성하고, 이식 후 장치의 관절부(1,2)가 서로 관절 운동을 할 수 있도록, 장치는 적어도 이식을 위해 두 관절부(1,2)를 연결하는 임시 연결부(4)를 구비하고, 연결부(4)와 가능하다면 견고한 요소인 경계부
