Recent literature has emphasized the role of hand surgeons in screening patients with carpal tunnel syndrome (CTS) for amyloidosis by performing a carpal tunnel synovial biopsy during open carpal tunnel release (CTR). This has led to misconceptions about the diagnostic utility of synovial biopsy and the clinical evaluation of suspected amyloidosis. Controversy over carpal tunnel biopsy is exacerbated by minimally invasive advances in CTR procedures. This current perspective aims to determine the role of carpal tunnel synovial biopsy in amyloidosis and provide an update for hand surgeons regarding the nuances of amyloidosis. We conclude that carpal tunnel synovial biopsy should not be performed without CTS symptoms but only in patients meeting criteria for open CTR such as in those with severe symptoms which have failed nonoperative treatment and minimally invasive procedures are contraindicated. A screening approach for amyloidosis is proposed in patients presenting with CTS symptoms. Despite advances in the understanding, treatment, and diagnosis of amyloidosis, there remains a need for accurate, specific, and sensitive diagnostic tests.

Background: Transthyretin cardiac amyloidosis (ATTRCA) is a prevalent disease, and it can be associated with heart failure (HF), left ventricle hypertrophy (LVH), atrial fibrillation (AF), and aortic stenosis (AS).

Aim: The study aims to detect the prevalence of ATTRCA in the symptomatic AS population.

Method: A single-center prospective study screening for ATTRCA in patients diagnosed with symptomatic severe AS undergoing aortic valve (AV) intervention.

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.

Purpose: Thread release of the carpal tunnel is the most recent of several minimally invasive ultrasound-guided carpal tunnel release techniques. The purpose of this article is to provide a step-by-step guide for minimally invasive, ultrasound-guided thread release of the carpal tunnel focused on transecting the transverse carpal ligament with minimal damage to the palmar aponeurosis on anatomical specimens.

Methods: Fifteen ultrasound-guided carpal tunnel thread releases were performed on the wrists of soft-embalmed anatomical specimens, which were dissected immediately after the intervention.
