Bilateral costal cartilage fractures sustained in the gym during repeated bench press exercises

Costal cartilage fractures are common in high-energy blunt chest trauma but are frequently missed on imaging evaluation and accordingly underreported in the literature. In this report, we describe a case of a 32-year-old male who sustained bilateral costal cartilage fractures following repeated blunt trauma in the gym sustained during bench press exercises. The patient presented with a painful "clicking" of a rib in and out of place while bending or turning sideways. Initial chest X-ray and computed tomography (CT) imaging were reported negative for fractures; however, a closer inspection of the CT image revealed bilateral costal cartilage fractures. As the patient's symptoms improved over time, a conservative approach to treatment with regular analgesia and advice to avoid external impact on the fracture sites was adopted. This unique case highlights an unusual mode of trauma and diagnostic complexity of costal cartilage fractures.

Costal cartilage fractures in blunt polytrauma patients - a prospective clinical and radiological follow-up study

Purpose

To assess the healing of costal cartilage fractures (CCFX) in patients with blunt polytrauma with follow-up imaging and clinical examination. Effect on physical performance and quality of life (QoL) was also evaluated.

Methods

The study group comprised twenty-one patients with diagnosed CCFX in trauma CT. All the patients underwent MRI, ultrasound, ultra-low-dose CT examinations, and clinical status control. The patients completed QoL questionnaires. Two radiologists evaluated the images regarding fracture union, dislocation, calcifications, and persistent edema at fracture site. An attending trauma surgeon clinically examined the patients, with emphasis on focal tenderness and ribcage mobility. Trauma registry data were accessed to evaluate injury severity and outcome.

Results

The patients were imaged at an average of 34.1 months (median 36, range 15.8–57.7) after the initial trauma. In 15 patients (71.4%), CCFX were considered stable on imaging. Cartilage calcifications were seen on healed fracture sites in all the patients. The fracture dislocation had increased in 5 patients (23.8%), and 1 patient (4.8%) showed signs of a non-stable union. Four patients (19.0%) reported persistent symptoms from CCFX.

Conclusion

Non-union in CCFX is uncommon but may lead to decreased stability and discomfort. Both clinical and radiological examinations play an important part in the post-traumatic evaluation of CCFX. CT and MRI visualize the healing process, while dynamic ultrasound may reveal instability. No significant difference in QoL was detected between patients with radiologically healed and non-healed CCFX. Post-traumatic disability was mostly due to other non-thoracic injuries.

Prevelance of the costal cartilage fracture on the computerised tomography in chest trauma

INTRODUCTION

Radiography remains limited in costal cartilage injuries, and sonography, CT and MR imaging turns out to be more sensitive in the detection of cartilage injuries. This study aims to determine the frequency of costal cartilage fractures detected in the CT images of the patients with high energy chest trauma and to evaluate the association of costal cartilage fracture with the complications of trauma.

METHODS

The CT images of 93 patients aged 18-91 years with a trauma admitted to the Emergency Department of the State Hospital between February 2019 and June 2019 were studied retrospectively. Thorax CT images of 93 patients who presented to the emergency department with blunt chest trauma with AIS > 2 were retrospectively investigated by a radiologist with a board certificate who had 15 years of experience in the field.

RESULTS

Costal cartilage fracture was identified in 39 of 93 patients with severe chest trauma. Among the 93 chest trauma patients admitted to the emergency department between February and June 2019, the prevalence of costal cartilage was calculated as 41.93%. Note that the most common costal cartilage fractures in the study group were identified in the 6th, 7th, 8th and 1st costal cartilages. Another significant relationship (p = 0.007) was found between costal cartilage calcification and cartilage fracture.

CONCLUSION

Costal cartilage fractures frequently occur in blunt thoracic trauma with multiple rib fractures and are of clinical importance as they lead to the instability of chest wall. The incidence of cartilage fractures increases in elderly patients with costal cartilage calcification.
