Prosthetic-free ribs stabilization technique in critical complex chest wall traumas: first results and experiences

BACKGROUND: Surgical stabilization in complex chest wall traumas, especially in case of posterior ribs arch destruction and flail chest, still remains a challenge for thoracic and trauma surgeons. Throughout the years different techniques and materials developed to address the complex anatomy of the ribs and reach an adequate fixation. Our aim is to present a prosthetic-free ribs stabilization technique which is easily reproducible and can achieve an efficient mechanical stabilization of the chest wall. METHODS: This surgical technique can be summarized in three steps: muscle sparing thoracotomy following modified “Shaw-Paulson’s” technique (complete section of the latissimus dorsi muscle along the transverse processes of vertebral spine to rich the serratus muscles plane), prosthetic-free ribs fixation with single stiches (Maxon™ 1) and muscles repositioning. RESULTS: Between January 2018 and June 2020, we retrospectively evaluated ten consecutive patients (six male and four female) which underwent a chest wall stabilization because of a posterior ribs destruction and flail chest. No chest wall deformities were observed during follow-up with CT-scan after 4, 30 and 90 days and no patient underwent additional early or late stabilization procedures. CONCLUSIONS: In the case of severe thoracic trauma with chest wall destruction and flail chest, modified “Shaw-Paulson approach” and prosthetic-free fixation technique with Maxon thread should be considered as a valuable option allowing an adequate stabilization of the chest with optimal respiratory function.
