Recurrent Slipping Rib Syndrome: Initial Experience with Vertical Rib Stabilization Using Bioabsorbable Plating.

Background: Slipping rib syndrome (SRS) is an often underdiagnosed cause of lower chest wall and abdominal pain. The diagnosis of SRS is established by physical examination with or without dynamic ultrasound. The pain can be debilitating and surgical excision of the nonattached, subluxing cartilages is curative for most patients, but frustratingly, up to a quarter of patients have transient or limited relief and require reoperation. Some of these patients were found to have subluxation of the remaining bony ribs, suggesting that excision of rib cartilage alone may not be curative in a subset of patients. Materials and Methods: A retrospective review was performed of 3 patients with recurrent slipping rib pain and hypermobile bony ribs on reoperation. In an effort to stabilize the hypermobile ribs, vertical bioabsorbable plating across their ribs was performed. The plates secure the ribs apart from each other, preventing the movement of ribs against each other and therefore the pain. Results: All patients tolerated the procedure well. Mean length of stay was 2.6 days. Mean follow-up is 7 months and all report significant improvement in pain. Conclusions: Rib plating allows stabilization of hypermobile ribs, while preserving the patient's anatomical rib cage, and is a safe treatment for recurrent pain after the initial procedure. This is a novel approach in patients with recurrent slipping rib symptoms.
