Technical Field
The invention relates to the technical field of medical instruments, in particular to an annular external fixator assembly capable of correcting rotation deformity.
Background
In the traditional external fixation, a splint or plaster is usually adopted to fix the fracture outside the skin, and because the splint or plaster is separated from the fracture by soft tissues such as muscles, blood vessels, nerves and the like, the fracture end has a room for movement, so that the anatomical contraposition alignment is difficult to achieve; the muscle disuse atrophy caused by the subsidence of swelling and ineffective movement of the affected limb caused by trauma aggravates the external fixation loosening, thereby easily causing the fracture to cause the serious consequences of abnormal healing, delayed healing or bone nonunion.
The traditional annular external fixator can fix, prolong and move bones well, and can conveniently correct angulation and poor contraposition deformity, but the traditional annular external fixator is very troublesome in correction of rotation deformity and complex in structure.
