RESUMEN
OBJECTIVE: To determine the effect of direct oral anticoagulants (DOACs) compared with warfarin on the 30-day readmission rates in patients with traumatic intracranial hemorrhage (ICH). METHODS: We conducted a retrospective review of patients from our hospital's trauma database admitted between June 2011 and October 2015 to our level II trauma center after sustaining a traumatic ICH while receiving anticoagulant therapy. Patients were stratified based on the anticoagulation drug (DOAC or warfarin) prescribed on admission. The readmission rates between the 2 groups were compared using χ2 analysis and multivariate logistic regression. Patients who died during their initial admission were excluded. RESULTS: Over the 4-year period, 160 patients were admitted with traumatic ICH. Seventy-nine were receiving warfarin and 57 were receiving a DOAC at admission. Data collected included age, sex, injury severity score, admission Glasgow Coma Score, Abbreviated Injury Scale (head), mechanism of injury, hospital and intensive care unit lengths of stay, discharge destination (eg, home, rehabilitation facility, nursing facility), comorbidities, operative interventions, readmissions, and reasons for the readmissions. The rate of readmission for rebleeding of ICH was significantly lower in the DOAC group compared with the warfarin group (5.3% vs. 17.7%; P = 0.04). Multivariate logistic regression suggests that warfarin use, but not DOAC use, is associated with increased readmission both for all causes and for ICH rebleeding. CONCLUSIONS: Warfarin use is associated with higher readmission rates in patients with intracranial bleeding for both all-cause readmissions and for intracranial rebleeding.

OBJECT: Pedicle screw fixation with transverse process fusion has gained widespread acceptance since its inception. Improved rates of arthrodesis have been demonstrated when this technique is used. The authors present one of the largest series of patients to undergo this procedure at a single center; one of the goals was to correlate construct length and spinal disease with rates of successful arthrodesis by conducting a prospective analysis of lumbar fusion in which pedicle screws were placed. METHODS: During a 7-year period, the senior author performed pedicle screw fixation with posterolateral fusion in 457 patients; the mean follow-up period was 28.4 months. Indications for fusion included metastatic tumor, single-level degenerative disc disease (DDD), trauma, degenerative scoliosis, and translational vertebral instability. Successful fusion was based on the radiographic demonstration of a bilateral contiguous osseous bridge over the transverse processes and absence of movement on dynamic x-ray films. Fusion rates were lowest in cases of tumors (54%) and highest in cases of trauma (96%). In patients with single-level DDD the rate was 91%, and in those with translational instability it was 89%. Fusion rates, however, declined steeply in relation to each additional motion segment in the translational instability group. In this group a strong linear trend for proportion was demonstrated (p < 0.001). The overall fusion rate in patients with degenerative scoliosis was 70%. The overall fusion rate for the entire group was 86%. CONCLUSIONS: The data in this study can be used as a benchmark with which to compare newer technologies. Although overall pedicle screw-assisted fusion rate in cases of trauma or selected degenerative lesions approached 90%, the arthrodesis rates are not uniform for the different diagnoses. This appears to be related to the underlying spinal disease and the number of segments included in the fusion.

OBJECT: The authors undertook a retrospective single-institution review of 261 patients who underwent anterior cervical corpectomy, reconstruction with allograft fibula, and placement of an anterior plating system for the treatment of cervical spinal stenosis to assess fusion rates and procedure-related complications. METHODS: Between October 1989 and June 1995, 261 patients with cervical stenosis underwent cervical corpectomy, allograft fibular bone fusion, and placement of instrumentation for spondylosis (197 patients), postlaminectomy kyphosis (27 patients), acute fracture (25 patients), or ossification of the posterior longitudinal ligament (12 patients). All patients suffered neck pain and cervical myelopathy or radiculopathy refractory to medical management. Of the procedures, 133 involved a single vertebral level (two disc levels and one vertebral body), 96 involved two levels, 31 involved three levels, and a single patient underwent a four-level procedure. Clinical and radiographic outcomes were assessed postoperatively and at 6-month intervals. The mean follow-up period was 25.7 months (range 24-47 months). Successful fusion was documented in 226 patients (86.6%). A stable, fibrous union developed in 33 asymptomatic patients (12.6%), whereas an unstable pseudarthrosis in two patients (0.8%) required reoperation. There were no cases of infection, spinal fluid leakage, or postoperative hematoma. Complications included transient unilateral upper-extremity weakness (two patients), dysphagia (35 transient and seven permanent), and hoarseness (35 transient and two permanent). In 14 patients (5.4%) radiological studies demonstrated evidence of hardware failure. CONCLUSIONS: Cervical corpectomy with fibular allograft reconstruction and anterior plating is an effective means of achieving spinal decompression and stabilization in cases of anterior cervical disease. Symptomatic improvement was achieved in 99.2% of patients. In their series the authors found a fusion rate of 86.6% and rates of permanent hoarseness of 3.4%, dysphagia of 0.7%, and an instrumentation failure rate of 5.4%.
