Surgical management of multiple rib fractures in polytrauma patients: semi-damage control surgery.

: To investigate the timing and extent of surgery for rib fractures in polytrauma patients. : Data from polytrauma patients who underwent early and partial rib fracture fixation after successful resuscitation were retrospectively analyzed. The study encompassed demographic data, clinical data, and outcomes. : In total, 71 patients with polytrauma were included. ISS ranged from 16 to 50 with a mean score of 25.3±7.5. The median lactate level was 3.6 mmol/L (IQR: 3.1 to 4.5), the median base deficit (BD) was 8.2 mmol/L (IQR: 6.4 to 9.8) and the shock index (SI) median was 1.2 (IQR: 0.9 to 1.3). Total fractured ribs in 71 patients were 726; individually, the minimum and maximum number of fractured ribs was 3 and 22, respectively (median, 10; mean, 10.2 ± 4.0). The average time to surgery was 42.9±42.6 h. Specifically, 41(57.7%) received the surgery within 24h and 52 (73.2%) patients received the surgery within 3 days following successful resuscitation. A total of 246 (33.9%) ribs underwent open reduction and internal fixation with plate, 3.46 ribs for each patient, with high frequencies of the 6th (49, 19.9%), 5th (46, 18.7%), 4th and 7th ribs (both 36, 14.6%). The average length of ICU stay was 11.5 ± 7.5 days and the duration of hospitalization was 16.3 ± 9.9 days. No surgical site infection or mortality was observed. Early and partial rib fracture fixation to restore the relative stability of the thorax is safe and effective for polytrauma patients after successful resuscitation. This surgery strategy is called semi-damage control surgery.
