Long-term outcome after surgical management of symptomatic non-union rib fractures

• Introduction: Traumatic chest wall injuries are common however the incidence of non-union rib fractures is unknown. Previous studies have suggested that surgical management of symptomatic non-union rib fractures could be beneficial in selected patients, although many experience persisting pain despite surgery. The aim of this study is to investigate the long-term outcome after surgical management of symptomatic non-union rib fractures. Methods: This is a cross-sectional study including adults (≥18 years) managed surgically for symptomatic non-union rib fractures with plate fixation during the period 2010–2020 at Sahlgrenska University Hospital. Patients operated for acute chest wall injury or injury due to cardiopulmonary resuscitation were excluded. Patients answered standardized questionnaires concerning remaining symptoms and satisfaction with surgery, quality of life (QoL, EQ-5D-5 L) and disability (Disability Rating Index, DRI). Lung function, movement of chest wall and thoracic spine, and shoulder function (Boström index) were assessed. Results: Sixteen patients, 12 men and four women, with mean age 61.6± 11.1 were included in the study. The mechanism of injury was trauma in 10 patients and cough-induced injuries in five patients. Lung disease was significantly more prevalent in cough-induced injuries compared to traumatic injuries, 5 vs 1 (p = 0.008). The mean follow-up time was 3.5 years. Ninety-four percent were satisfied with the surgery and reported that their symptoms had decreased, although 69 % had remaining symptoms, especially pain, from the chest wall. Quality of Life was decreased with EQ-5D-5 L index 0.819 (0.477–0.976) and EQ-VAS 69 (10–100). Disability Rating Index was 31.5 (1.3–76.7) with problems running, lifting heavy objects, and performing heavy work. Predicted lung function was decreased with Forced Vital Capacity (FVC) 86.2 ± 14.2 %, Forced Expiratory Volume in 1 second (FEV1) 79.1 ± 10.7 % and Peak Expiratory Flow (PEF) 89.7 ± 14.5 %. Patients with cough-induced injuries had full shoulder mobility. Conclusions: Chest wall surgery for symptomatic non-union rib fractures results in decreased symptoms and patient satisfaction in most cases despite remaining symptoms, reduced lung function, chest wall movement, and QoL and persistent disability.
