Key Takeaway
Note that intercostal nerve cryoablation is associated with lower opioid use and shorter stays in rib fractures.

This systematic review and meta-analysis examined the role of intercostal nerve cryoablation (INCA) compared with surgical stabilization of rib fractures (SSRF) alone in adult patients. The analysis included 479 patients from observational studies, noting that the included research had an observational design and a small number of retrospective studies.

Key findings indicated lower postoperative opioid consumption with a mean difference of -140.14 morphine milligram equivalent (95% CI, -266.79 to -13.49; P = 0.03). ICU length of stay was shorter by a mean difference of -2.76 d (95% CI, -3.78 to -1.73; P < 0.0001). Hospital length of stay was also shorter by a mean difference of -1.79 d (95% CI, -2.79 to -0.80; P < 0.01).

Secondary outcomes showed lower postoperative intubation rates with a risk ratio of 0.47 (95% CI, 0.28-0.80; P < 0.01). Pneumonia incidence was lower with a risk ratio of 0.43 (P = 0.0506). No significant difference was found for tracheostomy rates or mortality. Safety data were not reported.

The authors note limitations including risk of bias and imprecision. The study type is observational, so associations persist but causality is not established. Practice relevance is not reported, and the overall certainty is very low.

Adults with broken ribs often face a long recovery filled with pain and heavy reliance on opioids. A recent analysis looked at a technique called intercostal nerve cryoablation, which uses cold energy to numb the nerves around the ribs. This approach was compared to standard surgery that only fixes the broken bones without numbing the nerves.

The data showed that patients receiving the nerve freezing treatment used significantly less pain medicine after their procedure. They also spent fewer days in the intensive care unit and left the hospital sooner than those who had surgery alone. The analysis also found lower rates of needing a breathing tube after surgery.

However, the findings come with important caveats. The studies included were mostly observational and looked back at past records, which can introduce errors. Because of this design and the small number of patients involved, the overall certainty of the results is very low. These results show associations rather than proving a direct cause and effect. More high-quality research is needed before this becomes a standard option.

What this means for you:
Freezing rib nerves may reduce pain medicine and hospital time, but evidence is currently weak.

INTRODUCTION: Rib fractures are common in trauma patients and are associated with significant morbidity due to pain-related respiratory compromise. Surgical stabilization of rib fractures (SSRF) improves outcomes in select cases, but postoperative pain can persist despite surgery. Intercostal nerve cryoablation (INCA) has emerged as a potential adjunct to enhance analgesia and recovery. This systematic review and meta-analysis evaluated postoperative outcomes associated with the use of INCA in conjunction with SSRF in adult patients with rib fractures. METHODS: We conducted a systematic search of seven databases (PubMed, Embase, Scopus, Web of Science, Cochrane Library, Virtual Health Library, ClinicalTrials.gov) from inception to March 16, 2025. Comparative studies involving adult trauma patients undergoing SSRF with or without INCA were included. The primary outcomes were postoperative opioid consumption, intensive care unit (ICU) length of stay, and hospital length of stay. Secondary outcomes included pneumonia incidence, postoperative intubation rates, tracheostomy rates, and mortality. Meta-analyses were performed using random-effects models, and the certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation framework. RESULTS: Four retrospective cohort studies comprising 479 patients were included. Relative to SSRF alone, SSRF with adjunctive INCA was associated with lower postoperative opioid consumption (mean difference [MD] -140.14 morphine milligram equivalent; 95% confidence interval (CI), -266.79 to -13.49; P = 0.03), shorter ICU stay (MD -2.76 d; 95% CI, -3.78 to -1.73; P < 0.0001), and shorter hospital stay (MD -1.79 d; 95% CI, -2.79 to -0.80; P < 0.01). Adjunctive INCA was also associated with lower postoperative intubation rates (risk ratio 0.47; 95% CI, 0.28-0.80; P < 0.01) and showed a borderline association with lower pneumonia incidence (risk ratio 0.43; P = 0.0506). No significant differences were identified for tracheostomy or mortality. The certainty of evidence was very low overall owing to risk of bias, imprecision, and the observational design of the included studies. CONCLUSIONS: Adjunctive INCA during SSRF was associated with lower postoperative opioid requirements, shorter ICU and hospital stays, and more favorable pulmonary outcomes in patients with rib fractures. These findings are encouraging but derive from a small number of retrospective studies with important methodological limitations and should therefore be interpreted as associative rather than causal. Prospective randomized trials are needed to determine whether these associations persist and to better define the role of INCA in the management of rib fractures.
