Reassure a parent about a toddler's bow legs and intoeing — OSCE

OSCE communication and shared-decision station: reassuring the parent of a two-year-old with physiologic genu varum and internal tibial torsion that the bowing and the intoeing are normal developmental variants, explaining the Salenius and Vankka curve and the natural history in plain language, addressing the fear that the child needs braces or special shoes, and agreeing on a safety-net review.

Prompt
The mother of a two-year-old boy is worried that his legs are still bowed and that his feet turn in when he walks. She has read online that he needs special shoes and possibly braces, she is anxious that he will be teased or that he will need an operation, and she wants to know what is wrong and what to do. Counsel her.

Communication framework

Establish what the mother already understands and fears. Ask her to tell you, in her own words, what she has noticed and what she is most worried about. The fear that he needs special shoes or braces, the anxiety about teasing or an operation, and the uncertainty about what is wrong are the three concerns you will spend the most time addressing. Acknowledge that her instinct to check was right, and that the good news is that what she has noticed is normal for his age. Do not launch into the explanation before you have heard her. [4]

Explain the developmental curve in plain language. Tell her that every baby is born with bowed legs, and that the legs straighten on their own over the first two years as the child stands and walks. Explain that the legs then go through a knock-kneed phase around age three to four before settling to the normal adult alignment by about seven to eight years. Use a simple drawing of the curve if it helps, and check her understanding by asking her to repeat back the key idea — that her son is on the part of the curve where bowing is still expected, and the legs will continue to straighten. [1]

Address the intoeing directly. Tell her that the intoeing comes from a slight inward twist of the shin bone that is very common in toddlers, and that it straightens on its own as the bone grows, usually by age four to five. Explain that he may trip a little more than other children, but that the intoeing does not cause arthritis, does not affect his athletic ability, and does not mean there is anything wrong with his hips or his development. The studies show that intoeing children run and play as well as any other child. [4]

Address the special shoes and braces honestly. Explain clearly that special shoes, braces, and corrective devices do not make the legs straighten any faster, and that the careful studies have shown they make no difference to the outcome. The best thing for his legs is normal activity, normal shoes, and time. An operation is not needed for the great majority of children, and it is reserved only for the rare older child with a severe persistent problem. Acknowledge that the online advice is often out of date, and that her instinct to ask rather than buy the device was the right one. [4]

Invite questions, give a safety-net, and confirm the shared decision. Ask whether she has any questions, and address the specific fears she raised at the start. Document the discussion, measure and photograph the legs for the follow-up, and agree on a review in six to twelve months. Give a clear safety-net: return sooner if the bowing gets worse rather than better, if one leg becomes much more bowed than the other, or if any pain, limp, or short stature emerges. The mother who feels heard, informed, and supported leaves reassured rather than anxious, and the communication is as much a part of the management as the examination. [1] [4]
