A torus fracture, also known as a buckle fracture, is an incomplete break in the bone. It occurs when one side is pushed in while the other side bends out, according to Baylor Scott & White Health.
Torus fractures are more common in children than adults because their bones are softer, notes Baylor Scott & White Health. The fracture typically occurs in the wrist or forearm. Symptoms of a torus fracture include pain, swelling, redness, warmth, bruising and difficulty moving the area. Patients with a torus fracture wear a cast or splint around the area for about four to six weeks to set the bones and protect them.
