Table 2 Complications after surgical fixation based on the presence and severity of chest wall injury

From: Complications of clavicle fracture surgery in patients with concomitant chest wall injury: a retrospective study

Variable Group p-value
No-CWI (n = 226) CWI (n = 90) Minor-CWI (n = 36) Complex-CWI (n = 54)
Complications
 Overall 31 (13.7%) 16 (17.8%) 4 (11.1%) 12 (22.2%) 0.35
 Surgery-related 28 (12.4%) 6 (6.7%) 2 (5.6%) 4 (7.4%) 0.29
  Union-related 7 (3.1%) 0 (0) 0 (0) 0 (0) 0.13
  Implant-related 18 (8.0%) 5 (5.6%) 1 (2.7%) 4 (7.4%) 0.65
  Wound/Infection 3 (1.3%) 1 (1.1%) 1 (2.7%) 0 (0) 0.70
Unplanned readmission
 30-day 4 (1.8%) 5 (5.6%) 0 (0) 5 (9.3%) 0.02
 90-day 10 (4.4%) 9 (10.0%) 2 (5.6%) 7 (13.0%) 0.082
  1. Overall complications include surgery-related complications and unplanned readmission
  2. Union related complications included nonunion or delayed union
  3. Subgroup analysis showed complex CWI group had significantly higher rate of unplanned 30- and 90-day readmission than no-CWI group (p-value = 0.005 and 0.018, respectively) (Additional file 1: Table S2)
  4. CWI chest wall injury
