They are applicable to various types of rib fractures such as emergency treatment, car accidents, construction trauma, multiple rib fractures, flail chest and obvious displacement. Compared with traditional internal rib fixation technology, the rib encircling connector, made by special technology, is more aligned with the physiological curvature of human ribs. It can effectively treat various forms of rib fractures, without stimulating tissues. The rebounding and pressurization of the back of the arch is continuous and stable. It will not loosen due to early bone absorption, bone healing and human movement of the fracture ends.
