[Slipping rib syndrome in paediatrics: report of 4 cases]

The slipping rib syndrome (SRS) is an unknown pathology for the pediatric surgeon due to its low incidence in children. The weakness of the costal ligaments allowing an area of rib hypermobility has been postulated recently as the main etiology. It produces an intermittent pain in the lower thorax or upper abdomen that can affect to the daily activities and can be the origin of unspecific chronic pain.

A retrospective review of patients diagnosed with SRS between october 2012 and march 2017 was performed. Data of demographics, symptoms, imaging studies, surgical findings and long-term follow-up were collected.

During this period, 4 patients were diagnosed with SRS. Median age at diagnosis was 13 years (12-15 years) with a mean duration of symptoms of 13 months (12-36 months). In 2 patients the SRS was associated with Costal Dysmorphia (CD). The initial diagnosis was clinical with posterior ultrasound confirmation. Resection of the affected cartilages was performed in 3 patients and after a follow-up of 6 months (3-30 months), they all are painless and refer a good cosmetic result. One patient refused the intervention.

The SRS is an infrequent cause of thoracic pain with an etiology not well understood. The awareness of this disease and its typical presentation can avoid unnecessary studies. The resection of the affected cartilages is a safe and effective treatment.
