Operative fixation of rib fracture nonunions

Conservative Treatment of Empyema Formation Following Intrathoracic Rib Fixation With Antibiotics and Tissue Plasminogen Activator/Dornase

Rib plating is a recommended intervention for patients with multiple rib fractures or flail chest to improve shortness of breath, significantly reduce pain, and shorten the length of hospital stay. Here, we report a unique and extremely rare finding in a patient with empyema following intrathoracic rib fixation. A 32-year-old male with a history of alcohol use disorder presented to the emergency department trauma bay after a motor vehicle accident. Computed tomography (CT) showed right hemopneumothorax and fourth to ninth rib fractures with displacement. The right fifth and sixth ribs were then plated using a titanium RibFix bridge, implanted intrathoracically along the posterior surface of the ribs. On postoperative day 11, the patient developed an empyema and a CT-guided drainage catheter was placed into the collection. The patient was given a 3-day course of tissue plasminogen activator (tPA) and DNase for the treatment of his empyema. On postoperative day 15, a repeat CT scan demonstrated significant improvement in the empyema with evidence of abscess resolution. Antibiotics were discontinued after a total of 7 days and the patient was discharged on postoperative day 20. This case report contributes information to the management of complications in intrathoracic rib fixation.

Management of non-union of rib fractures secondary to trauma: A scoping review

OBJECTIVE

Rib fracture non-union is an uncommon complication of traumatic rib fractures. Our objective was to perform a scoping review of the literature for the management of rib fracture non-union. This included analysis of the variations in surgical technique, complications experienced, and reported outcomes.

METHODS

We conducted a scoping review and searched databases (MEDLINE, CINAHL, and Embase). We performed abstract and full-text screening, and abstracted data related to pre-operative assessment, surgical technique, complications, and reported outcome measures.

RESULTS

We included 29 articles of which 19 were case reports and 10 were case series. The data quality was generally heterogeneous. The studies included 229 patients and the commonest symptoms of rib fracture non-union included chest pain, clicking, dyspnea and deformities. The patients underwent surgical management of rib fracture non-union (excluding first rib fractures) using various techniques. The majority used surgical stabilization of rib fracture with or without a graft. The reported outcomes were inconsistent between studies, but showed high rates of union (>94 %), reduction in reported VAS scores, and improved return to work when included. Implant failure occurred in 10 % of the 229 total patients reported in our studies, the re-operation rate was 13 %, and the overall complication rate was 27 %.

CONCLUSION

Surgical management of rib fracture non-union often involving locking plates and screws with or without a graft has been shown in several case reports and series as an effective treatment with acceptable implant failure and complication rates. Surgical management is therefore a viable option for symptomatic patients. Further research is required to determine optimal management strategies that further reduce surgical complications for these patients.

Symptomatic rib fracture nonunion: a systematic review of the literature

INTRODUCTION

Rib fractures commonly occur in trauma patients with varying presentations. Though the literature in recent years has moved toward favoring more early intervention of acute rib fractures, little has been reported on the matter of surgical fixation for symptomatic rib fracture nonunions.

MATERIALS AND METHODS

We performed a review of PubMed and Cochrane databases for articles published since 2000. Inclusion criteria were studies with greater than six months of follow-up, while case studies were excluded. A thorough analysis was performed on patient outcomes, complications reported, operative techniques utilized, and fixation systems used, among other parameters reported by the articles.

RESULTS

One hundred and thirty-nine studies resulted from our review, and a total of nine studies met our inclusion criteria with a combined total of 182 patients who underwent open reduction and internal fixation for symptomatic rib fracture nonunions. All studies reported a significant reduction of pain with increased satisfaction in the majority of patients. There were a total of 71 postoperative complications, the most common of which included surgical site infections, hardware failure, and hematoma. The most serious complications were insulting injury to the lung parenchyma or pleura; however, these were extremely rare based off the current literature. The use of bone grafting was common with eight of the nine studies mentioning the benefits of grafting.

CONCLUSION

Surgical stabilization of rib fracture nonunions appears to be an appropriate treatment alternative, and various techniques and approaches may be used with similar success. Further studies with higher level of evidence are recommended on the subject.

Radiographic rib fracture nonunion and association with fracture classification in adults with multiple rib fractures without flail segment: A multicenter prospective cohort study

BACKGROUND

Rib fracture nonunion is a probable cause of chronic pain following chest trauma, although its prevalence remains unknown. The aims of this study were to determine rib fracture nonunion prevalence following nonoperative management and to determine if presence of nonunion was associated with the number of rib fractures, or the rib fracture classification of anatomical location, type, and displacement.

METHODS

This multicenter prospective cohort study included trauma patients with three or more fractured ribs but without a flail segment, who participated in the nonoperative management group of the FixCon trial between January 2019 and June 2022. The number and classification of rib fractures were assessed on trauma chest CT. Chest CTs conducted six months post-trauma were evaluated for the presence of nonunion. Radiological characteristics of nonunions were compared with normally healed rib fractures using the Mann-Whitney U, χ2 test, and Fisher's exact test as appropriate. A generalized linear model adjusted for multiple observations per patient when assessing the associations between nonunion and fracture characteristics.

RESULTS

A total of 68 patients were included with 561 post-traumatic fractures in 429 ribs. Chest CT after six months revealed nonunions in 67 (12 %) rib fractures in 29 (43 %) patients with a median of 2 (P25-P75 1-3) nonunions per patient. Nonunion was most commonly observed in ribs seven to 10 (20-23 %, p < 0.001, adjusted p = 0.006). Nonunion occurred in 14 (5 %) undisplaced, 22 (19 %) offset, and 20 (23 %) displaced rib fractures (p < 0.001). No statistically significant association between rib fracture type and nonunion was found.

CONCLUSIONS

Forty-three percent of patients with multiple rib fractures had radiographic nonunion six months after trauma. Fractures in ribs seven to 10 and dislocated fractures had an increased risk of rib fracture nonunion.

Chest Wall Injury Society recommendation for surgical stabilization of nonunited rib fractures to decrease pain, reduce opiate use, and improve patient reported outcomes in patients with rib fracture nonunion after trauma

BACKGROUND

Rib fractures are common injuries which can be associated with acute pain and chronic disability. While most rib fractures ultimately go on to achieve bony union, a subset of patients may go on to develop non-union. Management of these nonunited rib fractures can be challenging and variability in management exists.

METHODS

The Chest Wall Injury Society's Publication Committee convened to develop recommendations for use of surgical stabilization of nonunited rib fractures (SSNURF) to treat traumatic rib fracture nonunions. PubMed, Embase, and the Cochrane database were searched for pertinent studies. Using a process of iterative consensus, all committee members voted to accept or reject the recommendation.

RESULTS

No identified studies compared SSNURF to alternative therapy and the overall quality of the body of evidence was rated as low. Risk of bias was identified in all studies. Despite these limitations, there is lower-quality evidence suggesting that SSNURF may be beneficial for decreasing pain, reducing opiate use, and improving patient reported outcomes among patients with symptomatic rib nonunion. However, these benefits should be balanced against risk of symptomatic hardware failure and infection.

CONCLUSION

This guideline document summarizes the current CWIS recommendations regarding use of SSNURF for management of rib nonunion.

Outpatient Surgery for Rib Fracture Fixation: A Report of Three Cases

Rib fractures are common injuries observed in trauma patients that will often heal without operative intervention. However, patients can infrequently have continued pain. Operative fixation of these symptomatic rib fractures has traditionally led to the patient requiring hospital admission for observation and pain control. The purpose of this study was to review three cases of outpatient rib fracture, open reduction and internal fixation (ORIF) surgery. Three patients with symptomatic rib fractures treated with ORIF at a single urban level one trauma center underwent outpatient same-day surgery. Pertinent demographic, clinical, radiographic, and surgical data were collected. All patients had decreased preoperative pain and no complications. This case series demonstrates that outpatient surgery for rib fracture ORIF can be performed safely in a select patient population. Additionally, it has similar efficacy as inpatient operative fixation with the main added benefit being decreased costs to both the patient and the healthcare system. We suggest that outpatient operative fixation of rib fractures should be considered for select patients.
