Costal cartilage excision for the treatment of pediatric slipping rib syndrome.

Background: Costal cartilage excision is an effective treatment of slipping rib syndrome (SRS), although the diagnosis of SRS may be elusive. We review our experience with SRS in the pediatric patient.

Methods: This is a retrospective review from 2000 to 2011 of patients presenting with symptoms of SRS before 18 years of age.

Results: Seven patients were identified who were diagnosed with SRS and underwent costal cartilage excision. All patients presented with unilateral chest pain that was exacerbated by activity. Five patients reported a popping or clicking sensation with activity that was associated with pain. On physical examination, all patients had reproducible pain with palpation over the affected cartilage. Four patients had a mobile or popping rib with palpation, and 4 also had chest wall asymmetry. Five patients underwent imaging, and 4 patients were referred to specialists. It was a median of 2 years (0-5 years) from onset of symptoms to resection. At resection, all cartilages were grossly abnormal. There were no postoperative complications. Follow-up was complete for all patients over a median 0.9 years (0.2-2.0 years). One patient had recurrence of pain in a different location; another had persistent pain, which was less severe.

Conclusions: Slipping rib syndrome presents with costal cartilage pain that is reproducible on physical examination and commonly associated with a mobile rib. Excision of the affected cartilage(s) is an effective treatment and should be considered early to avoid unnecessary diagnostic tests and evaluation, which delay definitive therapy.
