Operative Stabilization of Chest Wall Trauma: Single-Center Report of Initial Management and Long-Term Outcome

Conservative treatment of even severe thoracic trauma including flail chest was traditionally the standard of care. Recently, we reported possible benefits of surgical chest wall stabilization in accordance with other groups. The aim of this study was to critically review our indications and results of internal fixation of rib fractures in the long-term course.

We retrospectively analyzed the data of a consecutive series of patients with internal rib fracture fixation at our institution from 8/2009 until 12/2014, and we retrospectively studied the late outcome through clinical examination or personal interview.

From 1398 patients, 235 sustained a severe thoracic trauma (AIS ≥3). In 23 of these patients, 88 internal rib fixations were performed using the MatrixRIB^® system. The median age of these operated patients was 56 years [interquartile range (IQR) 49-63] with a median ISS of 21 [IQR 16-29]. From 18 local resident patients, follow-up was obtained after an average time period of 27.6 (12-68) months. Most of these patients were free of pain and had no limitations in their daily routine. Out of all implants, 5 splint tips perforated the ribs in the postoperative course, but all patients remained clinically asymptomatic. Plate osteosynthesis showed no loss of reduction in the postoperative course. No cases of hardware prominence, wound infection or non-union occurred.

In our carefully selected thoracic trauma patients, locked plate rib fixation seemed to be safe and beneficial not only in the early posttraumatic course, but also after months and years, patients remain asymptomatic and complete recovery as a rule.
