OBJECTIVE Penetrating gunshot wounds (GSWs) to the spinal column are stable injuries and do not require spinal orthoses or bracing postinjury. Nonetheless, a high number of GSW-related spinal cord injury (SCI) patients are referred with a brace to national rehabilitation centers. Unnecessary bracing may encumber rehabilitation, create skin breakdown or pressure ulcers, and add excessive costs. ⋯ No patients deteriorated neurologically, whether or not they were initially braced. The unnecessary use of spinal orthoses increases costs and patient morbidity. Reeducation and dissemination of this information is warranted.

Multicenter Study
Vertebral compression fractures after stereotactic body radiation therapy: a large, multi-institutional, multinational evaluation.
OBJECTIVE The purpose of this study was to identify factors contributing to an increased risk for vertebral compression fracture (VCF) following stereotactic body radiation therapy (SBRT) for spinal tumors. METHODS A total of 594 tumors were treated with spinal SBRT as primary treatment or re-irradiation at 8 different institutions as part of a multi-institutional research consortium. Patients underwent LINAC-based, image-guided SBRT to a median dose of 20 Gy (range 8-40 Gy) in a median of 1 fraction (range 1-5 fractions). ⋯ CONCLUSIONS A VCF following SBRT is more likely to occur following treatment for a solitary spinal metastasis, reflecting a more aggressive treatment approach in patients with adequately controlled systemic disease. Higher prescription dose and a preexisting VCF also put patients at increased risk for post-SBRT VCF. In these patients, pre-SBRT cement augmentation could be considered to decrease the risk of subsequent VCF.

OBJECTIVE Transfer of the spinal accessory nerve to the suprascapular nerve is a common procedure, performed to reestablish shoulder motion in patients with total brachial plexus palsy. However, the results of this procedure remain largely unknown. METHODS Over an 11-year period (2002-2012), 257 patients with total brachial plexus palsy were operated upon in the authors' department by a single surgeon and had the spinal accessory nerve transferred to the suprascapular nerve. ⋯ In these patients, the average range of motion measured from the thorax was 87° (SD 40.6°). CONCLUSIONS In total palsies of the brachial plexus, using the spinal accessory nerve for transfer to the suprascapular nerve is reliable and provides some recovery of abduction for a large majority of patients. In a few patients, a more extensive approach to access the suprascapular nerve, including, if necessary, dissection in the suprascapular fossa, may enhance outcomes.

Comparative Study
Modeled cost-effectiveness of transforaminal lumbar interbody fusion compared with posterolateral fusion for spondylolisthesis using N(2)QOD data.
OBJECTIVE Transforaminal lumbar interbody fusion (TLIF) has become the most commonly used fusion technique for lumbar degenerative disorders. This suggests an expectation of better clinical outcomes with this technique, but this has not been validated consistently. How surgical variables and choice of health utility measures drive the cost-effectiveness of TLIF relative to posterolateral fusion (PSF) has not been established. ⋯ However, with EQ-5D-based QALYs, TLIF would become cost-prohibitive at an increased surgical cost of $2960 relative to that of PSF. With the 2014 US per capita gross domestic product of $53,042 as a more stringent cost-effectiveness threshold, TLIF would become cost-prohibitive at surgical costs $2562 above that of PSF with SF-6D-based QALYs or at a surgical cost exceeding that of PSF by $1570 with EQ-5D-derived QALYs. CONCLUSIONS As with all cost-effectiveness studies, cost per QALY depended on the measure of health utility selected, durability of the intervention, readmission rates, and the accuracy of the cost assumptions.
