To analyze 3T magnetic resonance imaging (MRI) findings and clinical features of patients with trigeminal neuralgia (TN) who underwent percutaneous balloon compression and to determine whether these findings had an impact on prognosis of TN. ⋯ Symptom duration was longer and microstructural changes were more apparent in patients with recurrence. In addition to age, comorbidities, and other clinical and radiographic features, symptom duration and FA values obtained with 3T MRI might be valuable information in surgical decision making.

Cervical and thoracic tandem spinal stenosis (ct-TSS) is a rare yet challenging degenerative disease. When the diagnosis is made, surgical decompression is indicated for both lesions. However, literature about the surgical approaches and prognosis of this disease is lacking. ⋯ The types of stenotic lesions should be considered when planning surgery for patients with ct-TSS. One-stage decompression is suitable for patients with adjacent stenotic lesions; staged procedures should be considered for other patients.

In situ decompression and transposition are equally effective in cubital tunnel syndrome treatment. Both are traditionally performed in the supine position. ⋯ In situ decompression is equally as effective as ulnar nerve transpositions but with fewer complications and recurrences. In the lateral decubitus position, the retroepicondylar tunnel is more accessible, allowing smaller incisions and better results.

It is expected that anatomic variations in the circle of Willis have a direct effect on blood flow in the internal carotid artery. Rupture of the lenticulostriate artery of the middle cerebral artery 1st segment (M1) is the most common cause of putaminal intracerebral hemorrhage (ICH), and we hypothesized that this could be related to the anatomic variations of the circle of Willis and the predominance of the anterior cerebral artery 1st segment (A1). ⋯ It was concluded that putaminal ICHs occur more frequently on the side of the dominant A1 segment. This information can help an understanding of the mechanism of putaminal spontaneous ICH development and may even assist in the treatment of ICH.

To investigate the role of lumbosacral transitional vertebra (LSTV) in the pathogenesis of adolescent lumbar disc herniation (ALDH) and the association between LSTV type and the herniation level of ALDH. ⋯ The LSTV is associated with LDH in adolescents and the sacralization of L5 may contribute to the L4/5 disc herniation in adolescent patients.
