Adulthood consequences of spinal deformity surgeries in neurofibromatosis type 1 patients.

Background: Spinal deformity associated with Neurofibromatosis type1(NF-1) is known to be intractable, and it's surgical outcome is known to be poor. However, it is not clear whether or not patients are able to lead a healthy social life as adults, and we investigated the surgical outcomes of patients who had reached adulthood after surgery.

Methods: Thirty-eight patients (16 males, 22 females) who had undergone spinal deformity surgery and had reached the age of 18 years at last follow up were included.

Osteophyte Bridge Formation Correlates with Vascular Calcification and Cardiovascular Disease in Diffuse Idiopathic Skeletal Hyperostosis.

Diffuse idiopathic skeletal hyperostosis (DISH) is a noninflammatory spondyloarthropathy characterized by ectopic calcification of spinal cord tissue. Its etiology is possibly polygenic. However, its pathogenesis and systemic effects remain unclear.

Broad and Asymmetric Lower Extremity Myotomes: Results From Intraoperative Direct Electrical Stimulation of the Lumbosacral Spinal Roots.

Study Design: Retrospective review of prospectively collected data.

Objective: This study aimed to accurately map the lower extremity muscles innervated by the lumbar spinal roots by directly stimulating the spinal roots during surgery.

Summary Of Background Data: Innervation of the spinal roots in the lower extremities has been estimated by clinical studies, anatomic studies, and animal experiments.

Evaluation of segmental mobility in patients with lumbar spondylolisthesis : A comparison of images from standing flexion-extension and standing/supine slippage.

Purpose: To evaluate segmental mobility with degenerative lumbar spondylolisthesis (DLS), upright lateral flexion-extension radiographs (FE) are widely used. However, some authors have described that a combination of lateral radiographs in the standing position and supine sagittal image (SS) reveal more segmental mobility than FE. The purpose of this study was to investigate the optimal method for evaluating segmental mobility with DLS.

Degenerative Lumbar Spondylolisthesis Patients With Movement-related Low Back Pain Have Less Postoperative Satisfaction After Decompression Alone.

Study Design: Retrospective analysis of prospectively collected multicenter observational data.

Objective: The aim was to examine the preoperative factors affecting postoperative satisfaction following posterior lumbar interbody fusion (PLIF) and microendoscopic muscle-preserving interlaminar decompression (ME-MILD) in patients with degenerative lumbar spondylolisthesis (DLS).

Summary Of Background Data: The technique involved in DLS surgery may either be decompression alone or decompression-fixation.

Extraforaminal Stenosis at L2-L3 Treated with Microendoscopic Surgery: Report of Two Cases.

Introduction: The many cases of far-out syndrome that have been reported have involved extraforaminal stenosis at L5-S1. We report two cases of extremely rare extraforaminal stenosis at L2-L3.

Case Report 1: A 59-year-old man presented with a 1/2-year history of the right leg pain.

Early Lymph Node Metastasis May Predict Poor Prognosis in Soft Tissue Sarcoma.

Background: Lymph node metastasis (LNM) is a relatively rare event in soft tissue sarcoma. An association between the timing of LNM detection and patient prognosis is presently unknown.

Patients And Methods: We retrospectively analyzed the clinicopathological features of 33 patients with LNM between 2001 and 2015.
