Slipping rib syndrome in an adolescent wrestler

Slipping rib syndrome is a commonly missed diagnosis of upper abdominal pain. It results from hypermobility of the anterior rib due to the disruption of the interchondral ligaments, most likely secondary to repetitive motions or some inciting event. The hypermobility leads to impingement of the intercostal nerves resulting in significant pain.A 10-year-old adolescent male child was evaluated for 4 months of intermittent, left-sided, upper abdominal pain following a wrestling injury. His paediatrician referred him for further evaluation after a negative workup given the patient was still having intermittent bouts of short-lasting pain that would spontaneously resolve. Physical examination demonstrated a positive hooking manoeuvre with associated swelling and prominence over the lower left ribs.In conclusion, a broad differential diagnosis, thorough clinical examination, and knowledge of slipping rib syndrome are important to appropriately diagnose and treat patients symptoms.
