Minimally Invasive Repair of Adult Slipped Rib Syndrome Without Costal Cartilage Excision.

BACKGROUND

Slipped rib syndrome (SRS) is a painful disorder caused when 1 or more of the 8th-10th false ribs become abnormally mobile. Established treatment modalities include analgesia, intercostal nerve injection, and costal cartilage excision. No definitive surgical correction of SRS without cartilage excision has been previously described. We aimed to determine whether a nonexcisional repair technique in affected adults could demonstrate significant relief from SRS using standardized outcome measures.

METHODS

We performed a retrospective review of cases of SRS treated at our institution in 2019. We obtained data by survey before and after sutured 10th rib fixation, using a self-reported rating scale from 0-10 at defined intervals. Surveyed outcome measures were compared pre- and postoperatively using the Wilcoxon signed rank sum test. The use of neural modulating, narcotic, and nonsteroidal antiinflammatory drug medications was also compared pre- and postoperatively using McNemar's test where applicable.

RESULTS

SRS was diagnosed using clinical examination alone in 42 adults and repaired in 29 patients. Median postoperative improvement in pain at 1 and 6 months was 75% (P < .001) and 80% (P < .001), respectively. Improvements in other outcome measures were similar. In patients who took pain medications preoperatively, narcotics were discontinued at 1 month by 100%, neural modulators by 86%, and nonsteroidal antiinflammatory drugs by 92% (all P values < .001). Pain medication use remained minimal at 6 months in 23 (79%) of patients completing follow-up.

CONCLUSIONS

Minimally invasive slipped rib repair in adults provides significant relief of SRS, offering a useful alternative to costal cartilage excision. It is well tolerated and effective.
