Table 3 Association of clinical and surgical outcomes between patients with isolated acetabular fractures (group C) and patients with combined acetabular fracture and spinal injury. Data are presented as means ± standard deviation (range) or % (n)

From: Patients with combined pelvic and spinal injuries have worse clinical and operative outcomes than patients with isolated pelvic injuries analysis of the German Pelvic Registry
