The authors report a case of median nerve compression due to a chondrosarcoma of the wrist. A 30 year-old right handed man complained of typical symptoms of median nerve compression. X-ray examination showed normal findings. During operation a more proximal lumbrical origin was the only abnormal finding. After nerve decompression pain relief was prompt. Six months later the patient again complained of symptoms of median nerve compression. Now X-ray examination showed scattered punctuate calcific densities of dystrophic calcification. The tumor was histologically shown to be a chondrosarcoma. It was treated by wide local excision and radiation therapy.

Background: Anatomical variations of the recurrent motor branch (RMB) are at risk of injury during carpal tunnel release procedures. Previous studies have visualized the RMB using ultrasound (US) and magnetic resonance imaging (MRI) but have not compared the imaging capabilities of the two. Previous investigations have overlooked two specific types of carpal tunnel syndrome (CTS): simultaneous compression of the median nerve and the RMB and isolated compression of the latter.

This study investigates the effects of photobiomodulation (PBM) with a 660-nm laser on nerve regeneration and muscle morphometry following median nerve axonotmesis in rats. Sixteen Wistar rats were divided into a control group and laser-treated group, with the latter receiving 10 applications of PBM (660 nm; 20 mW; 10 J/cm; 0.4 J; and 20 s) over 2 weeks.

Objective: To identify the sonomorphological appearance and to measure the thickness of the piriformis muscle (PM) and the proximal portion of the sacral nerve roots S1-S3 in healthy premenopausal women.
Materials And Methods: This prospective multicentric observational study included a consecutive series of women undergoing transvaginal sonography (TVS) at two tertiary gynecological referral centers. Standardized assessment of the pelvic organs was performed followed by an attempt to visualize the right and left PM and sacral nerve roots S1-S3 at their origin in proximity to the sacral neuroforamen.
Comparison of costoclavicular and lateral sagittal infraclavicular approaches in ultrasound-guided brachial plexus block.

Objectives: Lateral sagittal infraclavicular approach is frequently used because it has less risk of complications and provides rapid and adequate regional anesthesia. Due to the fact that the brachial plexus is deeper in the infraclavicular region and the approach angle is sharper, it can be technically challenging. In this study, we aimed to compare the costoclavicular approach, which is a newly defined approach, with the lateral sagittal infraclavicular brachial plexus block.

Introduction/aims: Reduced nerve sizes obtained by nerve ultrasound (NUS) have been proposed as a potential diagnostic marker for amyotrophic lateral sclerosis (ALS). However, prospective studies evaluating patients with suspected ALS are currently lacking. We, therefore, evaluated the diagnostic accuracy of a standardized NUS protocol in a large sample of suspected ALS patients.
