As with most minimally invasive spine procedures, lateral lumbar interbody fusion (LLIF) requires the use of biplanar fluoroscopy for localization and safe interbody cage placement. Computed tomography (CT)-based intraoperative spinal navigation has been shown to be more effective than fluoroscopic guidance for posterior-based approaches such as pedicle screw instrumentation. However, the use of spinal navigation in LLIF has not been well studied. ⋯ Use of an intraoperative cone-beam CT with an image-guided navigation system is feasible and safe and appears to be accurate, although a larger study is required to confirm these results.

6A.09: DIAGNOSIS OF SODIUM SENSITIVITY FROM MEAN ARTERIAL PRESSURE MEASURED AT THE ARM OR AT THE FINGER.
The severity of sodium sensitivity is quantified or 1) by the difference in mean arterial pressure (MAP) between high- and low-sodium diets (δMAP), or 2) by the sodium-sensitivity index (SSI), i.e. ratio between δMAP and the difference in urinary sodium excretion rates at the end of the two diets. MAP is usually measured with an arm cuff but the use of finger blood pressure monitors is rapidly increasing. Thus, our aim is to evaluate whether finger measures of MAP can be reliably used for assessing sodium sensitivity. ⋯ : The assessment of sodium sensitivity depends strongly on the MAP measurement site, with important discrepancies between brachial and finger measures.

4A.09: SAFETY AND PERFORMANCE OF THE ENLIGHTN RENAL DENERVATION SYSTEM IN PATIENTS WITH SEVERE UNCONTROLLED HYPERTENSION: 12 MONTH RESULTS FROM THE ENLIGHTN II STUDY.
Percutaneous sympathetic renal artery denervation is available for the treatment of patients with resistant hypertension. We further investigated the safety and efficacy of a multi-electrode renal denervation system (EnligHTN™) in patients with severe uncontrolled hypertension. ⋯ In this real world, post-marketing study we demonstrate that multi-electrode renal denervation results in durable, highly significant and safe lowering of both office BP and ambulatory BP parameters in patients with severe uncontrolled hypertension up to 12 months following treatment.

Ulnar nerve entrapment at the elbow is more than a compressive lesion of the nerve. The tensile biomechanical consequences of entrapment are currently marginally understood. ⋯ This work provides a framework for evaluating regional nerve kinematics. Suppressed translation due to tethering shifted the location of high strain from articular to more distal regions of the ulnar nerve. The authors hypothesize that deformation is thus shifted to a region of the nerve less accustomed to high strains, thereby contributing to the development of ulnar neuropathy.

There is an increasing demand for surgery of degenerative spinal disease. Limited healthcare resources draw attention to the need for cost-effective treatments. Outpatient surgery, when safe and feasible, is more cost effective than inpatient surgery. ⋯ This series of 1449 consecutive outpatient microsurgical spine decompressions adds to the growing literature in favor of outpatient spinal surgery in properly selected patients. In our study, 99.8% of the patients were successfully discharged either to their homes or to a hotel on the day of surgery. The overall complication rate was 3.5%, surgical mortality was 0%, and only 1.5% had to be admitted to a hospital within 3 months after surgery.
