A Randomized Controlled Trial of Surgical Rib Fixation in Polytrauma Patients With Flail Chest

Clinical efficacy of surgical versus conservative treatment for multiple rib fractures: A meta-analysis of randomized controlled trials

BACKGROUND

There are still controversies between surgical treatment and conservative treatment for multiple rib fractures (MRFs). No consensus has been reached concerning the indications and timing of surgery. In this meta-analysis, we aimed to determine the optimal treatment for MRFs.

METHODS

Six databases (PubMed, Medline, Embase, Cochrane, Cnki, Wanfang Database) were retrieved for all eligible randomized controlled trials (RCTs) published before January 2020. MRFs were treated either with operative reduction and internal fixation or conservative treatment. The pertinent data were retrieved. The quality of RCTs was evaluated by the modified Jadad rating scale and meta-analysis was performed using RevMan 5.3 software.

RESULTS

Seven RCTs involving 538 MRFs patients (260 were treated surgically vs. 278 conservatively) were included in this meta-analysis. Compared with conservative treatment, surgical treatment resulted in shorter length of hospital stay (WMD -8.48; 95% CI -11.34 to -5.63; P < 0.001), length of ICU stay (WMD -5.72; 95% CI -7.31 to -4.13; P < 0.001) and duration of mechanical ventilation (WMD -4.93; 95% CI -8.79 to -1.07; P = 0.01), with a lower risk of complications including pneumonia (RR 0.40; 95% CI 0.30 to 0.53; P < 0.001) and chest wall deformity (RR 0.07; 95% CI 0.03 to 0.14; P < 0.001). The sensitivity analysis carried out by excluding one study with significant heterogeneity showed that the rate of tracheostomy was lower in the surgical group than in the conservative group (RR 0.44; 95% CI 0.28 to 0.71; P = 0.0008).

CONCLUSIONS

For patients with MRFs, surgical treatment resulted in faster recovery, a lower risk of complications and better prognosis than conservative treatment.

Late Operative Rib Fixation is Inferior to Nonoperative Management

BACKGROUND

Operative rib fixation (ORF) of traumatic rib fractures has been shown to decrease hospital length of stay (LOS), ventilator days, and mortality. ORF performed within 1 day of admission has been shown to have favorable outcomes compared to later ORF. This report examines the ORF experience over 10 years at a level I trauma center.

METHODS

ORF patients from January 2007-January 2018 were matched to nonoperative controls in a 1:2 ratio based on age, injury severity score (ISS), chest Abbreviated Injury Score (AIS), and head AIS. Patient demographic, injury, and outcome data were collected from the trauma registry and medical records. Hospital day of ORF was identified for each ORF patient. Hospital LOS, ICU LOS, ventilator days, and mortality were compared against matched nonoperative controls.

RESULTS

Ninety-five ORF patients were matched to 190 nonoperative patients. ORF patients had a higher number of rib fractures (9.6 vs 6.4, P < .001). ORF patients with short time to operation (0-2 days) had a shorter average hospital stay than those with delayed operations (11.8 vs 12.6 vs 13.4 vs 19.6 days, P = .003). ORF patients with operations performed 3-4 days and >6 days after admission also had statistically significant longer ICU LOS and ventilator days. Patient mortality was higher when ORF was performed after 6 days.

DISCUSSION

Early ORF may improve pulmonary function, patient outcomes, and decrease LOS. Shifting practice toward early fixation may help further solidify the benefits of this procedure in the treatment of blunt chest trauma.

Surgical fixation of rib fractures decreases intensive care length of stay in flail chest patients

Background

Nonoperative treatment is currently the standard therapy for rib fractures. However, there is a trend towards surgical fixation from conservative management over the last decade. While surgical fixation of rib fractures has shown promising results, its impact on the clinical results remains unclear based on the current literature. As such, the present study aims to compare the short-term outcomes of multiple rib fracture patients treated by surgical fixation with traditional conservative management.

Methods

Data for patients with multiple (three or more) rib fractures admitted to our department between January 2012 and January 2019 were retrospectively collected and analyzed. Propensity score matched patients were compared between those treated with surgical rib fixation and those of nonoperatively treated. Primary outcomes were hospital length of stay for multiple rib fracture patients, and intensive care unit (ICU) length of stay for flail chest patients. Secondary outcomes included in hospital mortality, ICU usage rate, duration of ventilator support, ventilator usage rate, and pneumonia.

Results

The study included 1,201 patients with mean age of 50.1±12.7 years, of whom 954 (79.4%) were male. The average number of rib fractures was 6.3±2.4, with a mean injury severity score of 20.5±7.3. Among them, 563 (46.9%) patients had surgical rib fixation and 638 (53.1%) patients received nonoperative treatment. There were 191 patients with a flail chest, 133 (69.6%) had operative rib fixation and 58 (30.4%) were nonoperatively treated. After propensity score match, the hospital length of stay was not significantly differed between surgery and conservative management in multiple rib fracture patients (10.7±3.4 vs. 10.2±3.8 days, P=0.067), nor were the secondary outcomes, in terms of in hospital mortality (0.9% vs. 1.1%, P=0.704), ICU usage rate (12.3% vs. 12.9%, P=0.820), duration of ventilator support (100.1±13.9 vs. 99.8±20.7 hours, P=0.822), ventilator usage rate (12.0% vs. 12.9%, P=0.732), and pneumonia (24.3% vs. 24.9%, P=0.861). For patients with a flail chest, shorter ICU length of stay was found to be associated with surgical rib fixation comparing with nonoperative treatment (5.5±1.9 vs. 6.7±2.1 days, P=0.011). No secondary outcomes such as in hospital mortality (4.4% vs. 4.4%, P=1.000), ICU usage rate (20.0% vs. 22.2%, P=0.796), duration of ventilator support (113.1±20.4 vs. 131.2±19.5 hours, P=0.535), ventilator usage rate (20.0% vs. 20.0%, P=1.000), pneumonia (28.9% vs. 31.1%, P=0.818) were significant different between the operative and nonoperative groups.

Conclusions

Surgical rib fixation results in a shorter ICU length of stay in patients with a flail chest, and a comparable outcome for patients with multiple rib fractures when compared with nonoperative treatment.

Rescue Re-Do Inline Osteosynthesis with Wire Cerclage for Failed Rib Plating of Multilevel Rib Nonunion

Rib nonunion is a rare occurrence that requires surgical management and has a high rate of failure that may necessitate repeated intervention. We present the case of successful rescue redo repair of previously failed plating of chronic nonunion for multilevel posterior rib fractures, reinforced by wire cerclage of the osteosynthesis plate. Our objective is to illustrate the feasibility of repeated interventions, and the technique to resolve this challenging problem.
