Most authors agree that where angulation is less than 20 degrees, manipulation for reduction is not required and only symptomatic support is required: this is usually in the form of a removable splint. Some advocate the reduction of a bowing fracture where angulation exceeds 20 degrees. In isolation, treatment of bowing fractures is debated 2. Treatment and prognosisīowing fractures usually accompany another fracture and in those cases, treatment is determined according to the type and severity of the accompanying injury. In some cases, there may be dislocation of the paired bone, e.g. radius, and this is usually diaphyseal (either greenstick or complete). There is usually an accompanying fracture of a paired bone, e.g. There is no fracture line or visible cortical injury. The bowing tends to be fluid and blend into the normal bone at either end. If the view is in the plane of the bow, the bone may appear completely normal 1. On a plain film, bowing of the bone can be visualised provided that the view is in a different plane to the direction of bowing. Microscopic examination of the bone reveals that there are microfractures along the concave border of the bowed bone, but these are not visible radiographically. If the force is greater than the mechanical strength of the bone, the bone undergoes plastic deformation and when the force is released, the bone remains in its bowed position. This quality makes splints ideal for the management of a variety of acute musculoskeletal conditions in which swelling is anticipated, such as acute fractures or sprains, or for initial. This ability to bend occurs because the cortex is thinner in absolute and relative terms compared to adult bones and because of the way the cortex and periosteum bind to each other in the developing skeleton. Paediatric bones have a degree of elasticity and therefore, if the force is low and subsequently released, the bone returns to its normal position and no lasting evidence of that bowing is seen radiographically. When an angulated longitudinal force is applied to a bone, the bone bends. This is often after falling from furniture or climbing equipment, especially monkey bars. Buckle fractures occur most often in the forearm (radius and ulna), near the wrist, as a result of a child falling on their hands. Clinical presentationĬhildren present with pain and swelling following a fall, usually on an outstretched hand. However, bowing fractures of all long bones have been described. The radius and ulna are the most commonly affected bones, followed by the fibula. These injuries usually occur in children although adolescents may be affected. fractures in carpal, radius, or ulna bones that often occur in children from falls onto outstretched hands or from direct blunt trauma distal forearm is the. It often occurs with a distal radius fracture. However, there have been several case reports of bowing in adult bones. An ulnar syloid fracture is a common type of wrist injury involving the end of the bony part of your wrist. 1, 2015, doi:10.1542/ fractures are almost exclusively found in children. Types of Forearm Fractures in Children Buckle or torus fracture: A stable fracture that compresses the bone on one side, forming a buckle on the opposite side. “Primary Care Physician Follow-up of Distal Radius Buckle Fractures.” Pediatrics, vol. One side of the bone buckles (bulges) when pressure is applied to the other side. New York, The McGraw-Hill Companies Inc., 2011, (Ch) 133 A buckle fracture is a break that does not go completely through the bone. Hopkins-Mann C, Ogunnaike-joseph D, Moro-Sutherland D: Musculoskeletal Disorders in Children, in Tintinalli JE, Stapczynski JS, Ma OJ, et al (eds): Tintinalli’s Emergency Medicine, ed 7. Your child has a buckle injury, which means there is a small area of compressed bone in the wrist This type of break is common in children, and normally heals.
