The goal of this monocentric observational study is to evaluate the outcomes of patients who underwent a delayed surgical stabilization of rib fractures/surgical stabilization of rib fracture nonunion (SSRFN) based on the timing of surgery after trauma.
Rib fractures occur in a significant number of patients with blunt chest trauma, and while conservative treatment remains the standard, surgical stabilization of rib fractures (SSRF) has shown improved clinical outcomes. However, conservative therapy often results in chronic chest pain and long-term incapacity, with up to 64% of patients experiencing persistent pain. Additionally, rib fracture nonunion, a condition where the bone fails to heal, affects approximately 12-15% of cases treated conservatively and can lead to long-term complications, including pain, limited mobility, and impaired quality of life.
This single-center observational study aims to analyze the outcomes of patients who underwent delayed SSRF (surgery between 3 weeks and 3 months after trauma) or nonunion SSRF (surgery performed more than 3 months after trauma). To assess whether a shorter interval between trauma and surgery results in better outcomes, the primary objective is to assess the persistence of thoracic pain in both patient groups. The secondary objective is to determine if SSRF improved patients' well-being.
This prospective research project is a single center analysis of existing data on patients, who underwent rib fixation for nonunion at the Department of Thoracic Surgery of the University Hospital Basel between January 1st, 2012 and June 30th, 2024. A prospective follow-up visit will be organized to assess the postoperative outcome.
The results of this study will provide valuable insights into optimizing treatment timelines for non consolidated rib fractures or rib fracture nonunion, improving patient outcomes and reducing long-term pain and disability.

| Measure | Description | Time Frame |
|---|---|---|
| Pain status at Follow-up (FU) | The pain status at the timepoint of the follow-up visit is measured using the numeric rating scale (NRS, scale 0: no pain to 10: worst pain) in different situations (at rest, at movement, and during deep inspiration). The type of pain (local, diffuse, neurogenic) will be also assessed. | After surgery at follow-up visit (1-8 weeks after recruitment) |
| Recommendation of the surgery to another person in a situation like the own | The patients will be asked if they would recommend the surgery to another person in a situation like the own. The assessment will be performed in two categories: yes/no. | After surgery at follow-up visit (1-8 weeks after recruitment) |
| Pain status at FU compared to before surgery | The pain status at the timepoint of the follow-up visit compared to the timepoint before surgery in five distinct categories on a Likert-scale (much better, slightly better, no change, slightly worse, much worse). | After surgery at follow-up visit (1-8 weeks after recruitment) |
| Painkiller Use (including nonsteroidal anti-inflammatory drugs and opioids) | The painkiller use including nonsteroidal anti-inflammatory drugs and opioids is being recorded. | After surgery at follow-up visit (1-8 weeks after recruitment) |
| Measure | Description | Time Frame |
|---|---|---|
| Health status | The subjective health-related quality of life is recorded using the 12-Item Short-Form (SF-12) questionnaire. The SF-12 is a validated scale used to assess physical and mental health, with scores ranging from 0 to 100, where higher scores indicate better health and well-being. | After surgery at follow-up visit (1-8 weeks after recruitment) |
| Measure | Description | Time Frame |
|---|---|---|
| Satisfaction with the decision for surgery | Satisfaction with the decision for surgery will be assessed by use of NRS (numerical rating scale). (Would you have let the surgery done again? 0=Yes, absolutely satisfied; 10= absolutely dissatisfied): | After surgery at follow-up visit (1-8 weeks after recruitment) |
| Satisfaction with cosmetic results |

| Resumption of daily/professional activity at FU | Resumption of former professional activity and daily activities will be assessed by use of the numeric rating scale (NRS, scale 0: no pain to 10: worst pain). | After surgery at follow-up visit (1-8 weeks after recruitment) |
| Resumption of daily/professional activity at FU compared to before surgery | Resumption of former professional activity and daily activities will be assessed by comparison with the situation before trauma and before surgery (much better, slightly better, no change, slightly worse, much worse). | After surgery at follow-up visit (1-8 weeks after recruitment) |
| Complications | Complications related to surgery until/at 30 d after surgery according to the Clavien-Dindo classification. | Day 30 after surgery |
| Correlation between Number of Broken Ribs, Fixed Ribs, and Impact on Patient Outcomes | This outcome assesses the relationship between the number of broken ribs, the number of surgically fixed ribs, and their influence on patient recovery and clinical outcomes. | After surgery at follow-up visit (1-8 weeks after recruitment) |
| Association between Age and clinical outcomes | This outcome measures the association between patient age and the clinical outcomes following rib fractures. | After surgery at follow-up visit (1-8 weeks after recruitment) |
