Match each classic clinical presentation with its most likely pediatric musculoskeletal diagnosis.
- An obese 13-year-old boy presents with a dull ache in his anterior thigh and an altered, waddling gait.Slipped capital femoral epiphysis
- A 6-year-old boy presents with an insidious onset of a painless limp and restricted hip internal rotation and abduction.Legg-Calvé-Perthes disease
- A 2-year-old girl holds her right arm pronated against her body after her father playfully swung her by the hands.Radial head subluxation
- A 14-year-old active female soccer player presents with anterior knee pain that worsens with jumping and climbing stairs.Osgood-Schlatter disease
Answer
The correct matches align the obese adolescent with Slipped capital femoral epiphysis, the 6-year-old with an insidious limp to Legg-Calvé-Perthes disease, the toddler with a traction injury to Radial head subluxation, and the active adolescent to Osgood-Schlatter disease.
Each clinical vignette provides classic demographic and symptomatic clues that point to a single highly specific diagnosis. Recognizing these age-dependent patterns is essential for appropriate orthopedic management.
