Brief Summary:
A retrospective review of demographics and adverse events from cases completed with the RibFix Advantage System. Evaluation of device integrity, and performance by a prospective CT scan with a minimum of 3 months post-implantation.

Condition or disease Intervention/treatment
Rib Fracture Multiple Device: RibFix Advantage

Detailed Description:

The RibFix Advantage System is a novel intrathoracic titanium plating system that is FDA-cleared for the treatment of rib fractures. The RibFix Advantage System is designed to be implanted in a less invasive procedure where plates are introduced and placed on the pleural cortex of the rib during video-assisted thoracoscopic surgery. Intrathoracic plate placement allows for smaller cutaneous incisions and less muscle disruption, which may aid in patient recovery compared to traditional open reduction internal fixation systems that are currently available.

The purpose of this study is to gather the first clinical data on this novel device in the context of a case series of patients with radiologic and quality-of-life follow-up.

Intervention Details:
  • Device: RibFix Advantage
    Class II device in the United States; consists of bridges (with locking posts) and locking caps for the thoracoscopic fixation and stabilization of ribs. These implants are manufactured from commercially pure titanium and titanium alloys. When fully assembled, the bridge plate is placed on the underside of the rib (pleural cortex); the threaded locking posts extend through pre-drilled holes in the rib, and the locking caps are fixed to the locking post on the anterior (cutaneous) side of the rib. The combined threaded locking post and cap provides for fixation of the bridge and stabilization of the fracture.

Primary Outcome Measures :
  1. Fracture stability [ Time Frame: 3 months post-implantation ]
    Evaluated by a computed tomography (CT) scan. Rib fractures repaired with RibFix Advantage should demonstrate continuity without overlap

  2. Device integrity [ Time Frame: 3 months post-implantation ]
    Evaluated by a computed tomography (CT) scan. Images should demonstrate no plate migration, no post/cap migration and no plate fracture

Secondary Outcome Measures :
  1. Adverse Events of Interest [ Time Frame: From the the date of implantation until the day of hospital discharge, or up to 10 days post-implantation, whichever occurs first; 30 days post surgery; 3 month post-implantation ]
    Includes: Chest infections, Empyema, Mediastinitis. Wound infection, Wound dehiscence, Chest wall deformity related to the device, Pleural effusion related to the device, Hemothorax related to the device, Pneumothorax related to the device and Hemo-pneumothorax related to the device
