Operative fixation of rib fracture nonunions

INTRODUCTION

Rib fractures are common injuries in trauma patients that often heal without intervention. Infrequently, symptomatic rib fracture nonunions are a complication after rib fractures. There is a paucity of literature on the surgical treatment of rib fracture nonunion. The purpose of this study was to describe the efficacy of rib fracture nonunion operative fixation with particular focus on surgical technique, healing rates, and complications.

MATERIALS AND METHODS

Patients aged ≥ 18 years with symptomatic rib fracture nonunions treated with open reduction and internal fixation (ORIF) with locking plates at a single urban level 1 trauma center were retrospectively reviewed. Pertinent demographic, clinical, radiographic, and surgical data were collected and analyzed.

RESULTS

A total of 18 patients met inclusion criteria. The mean time from injury to undergoing ORIF for rib fracture nonunion was just under a year and the number of ribs plated was 2.95 ± 1.16 (1-5 ribs) with bone grafting used in six cases. All patients (100%) showed evidence of healing at an average of 2.65 ± 1.50 months (2-8 months). All patients reported a decrease in pain. No narcotic pain medication was used at an average of 3.88 ± 3.76 weeks (0-10 weeks) post-operatively. Intraoperative and postoperative complications were found in 4 (22.2%) patients.

CONCLUSION

This study concluded that operative fixation of symptomatic rib fracture nonunion demonstrated favorable outcomes with reduction in preoperative pain levels, decreased use of narcotic pain medication, minimal complications, and a high rate of fracture union. This described method provides symptomatic relief, reduction in pain, and promotes bony healing of the fracture nonunion without development of major complications. We suggest that operative fixation should be considered as the primary method of treatment of symptomatic rib nonunions.

Far posterior rib plating: Preliminary results of a retrospective case series

INTRODUCTION

Far posterior, or paraspinal rib fractures, defined as fractures that are medial to the medial border of the scapula (and may involve the costovertebral articulation), are often treated nonoperatively. However, in certain cases, including severe displacement, persistent pain, nonunion, or persistent respiratory distress, stabilization with open reduction and internal fixation (ORIF) may be warranted. There is a paucity of literature regarding the surgical approach and clinical outcomes following ORIF for far posterior rib fractures and fracture-dislocations. The purpose of this paper is to describe the surgical approach and to report the first collection of clinical outcomes for patients undergoing paraspinal rib ORIF.

PATIENTS AND METHODS

A retrospective case series was performed at a single urban level 1 trauma center. Patients 18 years of age or older who underwent ORIF of far posterior rib fractures were included in this study. Far posterior rib fractures were defined as fractures that occurred medial to the medial border of the scapula underneath the paraspinal musculature. Data collection including patient demographics, injury characteristics, operative variables, and postoperative outcomes were collected and analyzed.

RESULTS

Twenty-six patients, with a mean age of 50.7 years, who underwent paraspinal rib ORIF were included in this study. The mean follow-up was 12.1 months. 80.8% of patients had a flail chest injury. On average, 3.4 ribs were instrumented posteriorly with 22.8% of patients requiring fixation spanning the costotransverse articulation. No intraoperative complications occurred. Only one patient required a repeat procedure. Total hospital length of stay averaged 17.3 days with an intensive care unit stay averaging 6.2 days. Total ventilator time averaged 4 days. 7 patients were diagnosed with postoperative pneumonia and 6 patients required tracheostomy.

CONCLUSION

Open reduction and internal fixation for far posterior, or paraspinal rib fractures and fracture-dislocations is a safe procedure with low complications rates and favorable postoperative outcomes including hospital length of stay, ICU length of stay, need for tracheostomy, postoperative pneumonia, and mechanical ventilation time.
