Explain an unstable slipped capital femoral epiphysis and the urgent operation to a parent — OSCE

Communication framework

Establish what the mother already understands and fears. Ask her to tell you, in her own words, what has happened so far and what she is most worried about. The fear for his walking and his future, the anxiety about the anaesthetic, and the confusion about the urgency are the three emotions you will spend the most time addressing, and you address them with plain language and with the evidence of why acting tonight protects his hip. Do not launch into the plan before you have heard her. [1]

Explain the diagnosis in plain language, without jargon. Tell her that her son has a slipped growth plate at the top of his thigh bone — the ball of the ball-and-socket hip joint — and that the ball has shifted on its neck because the growth plate that holds it in place has weakened during his growth spurt and given way under his weight. Avoid the terms epiphysis, physis, and capital realignment unless you translate them, and check her understanding by asking her to repeat back the key idea. The condition is treatable, and acting tonight gives him the best chance of a full recovery. [7]

Address the urgency directly and honestly. The reason the operation cannot wait for the morning is that the blood vessels supplying the ball of the hip joint travel along the neck of the bone, and the slip has kinked and stretched them. Because her son cannot walk on the leg, the slip is unstable, and the longer the ball sits in the slipped position, the higher the risk that the blood supply is lost permanently — which would mean a collapsed hip, a limp, and an artificial joint in early adulthood. The operation tonight repositions and fixes the bone to protect the blood supply, and the anaesthetic team will make him as safe as possible for it. Acknowledge that this is frightening and fast, and that you would not be recommending it if it were not necessary. [1] [10]
