Explain a torus fracture and the soft-bandage plan to a parent — OSCE

Communication framework

Establish what the mother already understands and fears. Ask her to tell you, in her own words, what she thinks has happened and what she is most worried about. The expectation of a cast, the worry that the bone will not heal or will move without one, and the uncertainty about how to know if something is wrong at home are the three concerns you will spend the most time on, and you address them with plain language and the evidence of why a soft bandage is safe for this particular fracture. Do not launch into the plan before you have heard her. ^[3]

Explain the fracture in plain language, without jargon. Tell her that her daughter has a buckle fracture, sometimes called a torus fracture, which is a small crumple of the hard outer layer of the bone at the wrist — like denting the side of a soft drink can without breaking through it. Because the bone is a child's bone it is softer and more bendy than an adult's, and rather than snapping cleanly it crumpled a little. This is a stable, common and very forgiving injury: the bone does not move out of place, and it heals fully within about three weeks. Check her understanding by asking her to repeat the key idea back. ^[7]

Address the cast expectation directly and honestly, with the evidence. The reason a rigid cast is not needed is that a buckle fracture is stable and cannot slip out of place, so holding it still in plaster does not change how it heals. A large research study — the FORCE trial — compared giving children with exactly this fracture a soft bandage against a rigid cast, and found that the bandage was just as good for healing, while the children given the bandage had less pain and could use their hand better day to day. A soft bandage or a removable splint is therefore the recommended treatment, and her daughter can take it off for washing and gentle use as the pain allows. Acknowledge that a cast feels more reassuring, and explain that the reassuring thing here is the stability of the fracture itself, not the firmness of the bandage. ^{[3] [2]}
