Lateral compression type B 2-1 pelvic ring fractures in young patients do not require surgery

According to Young and Burgess, type B 2-1 pelvic fractures are a type of lateral compression fracture (LC-1) and are the most common pelvic injury at all ages. Although they are considered unstable in rotation and despite biomechanical recommendations for anterior stabilization, most authors recommend non-operative treatment. However, studies comparing outcomes and complications regarding operative versus non-operative treatment are still scarce. Seventy-one patients aged under 65 years with a type B 2-1 pelvic fracture were treated between 2006 and 2011. Patients in Group I (n = 35) were treated non-operatively and patients in Group II (n = 36) were treated operatively. Postoperative complications, clinical course, and follow-up (VAS for Pain, SF 36, EQ-5D) of at least 1 year postoperatively were evaluated. Our data show that operatively treated patients had a significantly higher complication rate. Preoperatively, the only significant difference between the non-operative and operative groups was the amount of anterior fracture dislocation and the presence of an isolated pelvic ring fracture. In the postoperative follow-up, no significant differences were found regarding pain or quality of life. Type B 2-1 pelvic ring fractures in young patients should be treated non-operatively.
