After a fracture grows crooked refers to the deformity healing of the bone, after the fracture is repositioned, angulation within less than 10 degrees of physiological curvature is allowed, because angulation can restore the normal structure of the bone through bone shaping. If angulation within 10 degrees of physiological curvature is exceeded, or if angulation is not performed according to physiological curvature, surgery for correction is required. Traditional angulation surgery involves chiseling the fracture end and fixing it in a tubular cast for 2 months; this method often has complications, such as pressure sores and ischemic muscle spasm. Nowadays, a minimally invasive wedge osteotomy is mostly used, in which a plate is placed on the wedge osteotomy through a very small incision, which can reduce the complications of plaster fixation.
