Abstract

Purpose: Traumatic vertebral injuries have a prevalence of 4-5% at level I centers. Studies have demonstrated that isolated thoracolumbar transverse process fractures (iTPF) rarely require brace or surgical interventions. We hypothesized that similarly isolated thoracolumbar spinous process fractures (iSPF) would have less need for bracing and operative interventions than SPFs with associated vertebral body (VB) fractures (SPF+VB). We performed a similar analysis for iTPF compared to transverse process fractures associated with VB injury (TPF+VB). Methods: In this single-center, retrospective study from 2012 to 2016, patients were classified into iSPF, SPF+VB, iTPF, and TPF+VB groups. Data including the fracture pattern, neurologic deficits, and operative intervention were obtained. The primary outcome studied was the need for bracing and/or surgery. A statistical analysis was conducted. Results: Of 98 patients with spinous process fractures, 21 had iSPF and 77 had SPF+VB. No iSPF patients underwent surgery, whereas 24 (31.17%) SPF+VB patients did undergo surgery (p=0.012). In the iSPF group, three patients (15%) received braces only for comfort, whereas 37 (48.68%) of the SPF+VB group required bracing (p=0.058). Of 474 patients with transverse process fractures, 335 had iTPF and 139 had TPF+VB. No iTPF patients underwent surgery, whereas 28 (20.14%) TPF+VB patients did (p≤0.001). Of the iTPF patients, six (1.86%) were recommended to receive braces only for comfort, while 68 (50.75%) of the TPF+VB patients required bracing (p<0.001). Conclusions: No patients with iSPF or iTPF required surgical intervention, and bracing was recommended to patients in these groups for comfort only. It appears that these injures may be safely managed without interventions, calling into question the need for spine consultation.
