骨外固定器是基于骨折愈合与生物力学的原理，在骨折的近心和远心骨段经皮穿针或钉，再用合适的连接杆和固定夹把裸露在外的针端彼此连接起来，以达到治疗骨折目的的一种装置“’，它的出现。发展是骨伤治疗史上的一项了不起的成就。经过几代人的努力，骨外固定器技术已成为治 The external fixator is based on the principles of fracture healing and biomechanics. Percutaneous needles or nails are inserted through the proximal and distal segments of the fracture, and the exposed ends of the needles are connected to each other with appropriate connecting rods and clips. In order to achieve the purpose of treating bone fractures, a device "’, its emergence. Development is a remarkable achievement in the history of orthopedic treatment. After several generations of efforts, external fixation technology has become a rule.
