Purpose: Our aim was to study the dynamics of the post-surgical canal and nerve volumes and their relationships to objective [electromyoneurography (EMNG)] and subjective (pain) outcomes.
Methods: Forty-seven patients with carpal tunnel syndrome (CTS) (median age 52, range 23-75 years) with a prominent narrowing of the median nerve within the canal (observed during carpal tunnel release) were evaluated clinically using EMNG and magnetic resonance imagining (MRI) before and at 90 and 180 days post-surgery.
Results: Canal and nerve volumes increased, EMNG findings improved and pain resolved during the follow-up. Increase in tunnel volume was independently associated with increased nerve volume. A greater post-surgical nerve volume was independently associated with a more prominent resolution of pain, but not with the extent of EMNG improvement, whereas EMNG improvement was not associated with pain resolution.
Conclusions: Data confirm that MRI can detect even modest changes in the carpal tunnel and median nerve volume and that tunnel release results in tunnel and nerve-volume increases that are paralleled by EMNG and clinical improvements. Taken together, these observations suggest that MRI could be used to objectivise persistent post-surgical difficulties in CTS patients. Level of evidence 3 (follow-up study).

Introduction: This study sought to investigate the impact of the area deprivation index (ADI) on the treatment timeline from carpal tunnel syndrome (CTS) to carpal tunnel release (CTR). We hypothesize that increased social deprivation will correlate with increased time between care milestones from presentation to surgery.
Methods: This is a retrospective review of patients diagnosed with CTS who underwent CTR at a single academic institution.

Amyloidosis is a deadly systemic disease in which misfolded proteins accumulate in human tissue eventually leading to morbid dysfunction in multiple organ systems. The prognosis of untreated amyloidosis is poor. Orthopedic manifestations of amyloidosis include carpal tunnel syndrome (CTS), trigger digit, distal biceps tendon rupture, rotator cuff disease, and lumbar spinal stenosis.

In carpal tunnel syndrome (CTS), pain and sensory disturbance are the main symptoms, but thumb palmar abduction (TPA) paralysis cannot be ignored as a concurrent symptom. The reliable quantitative measurement of TPA power was not established. The purpose of this study was to report on the reliability of TPA strength measurements by the hand-held dynamometry (HHD) in large samples of CTS and its superiority over other tests, including grip, pinch powers, TPA angles and manual muscle testing, in terms of clinical progress indicators.

Flexible tactile sensors have received significant attention for use in wearable applications such as robotics, human-machine interfaces, and health monitoring. However, conventional tactile sensors face challenges in accurately measuring pressure because vertical deformation is induced by Poisson's ratio in situations where lateral strain is applied. This study shows a strain-insensitive flexible tactile sensor array without the crosstalk effect using a highly stretchable mesh.

Aims And Objectives: Dynamic incursion of lumbrical muscle proximal to the distal edge of transverse carpal ligament (TCL) has been long debated for its role in causing median nerve compression in the carpal tunnel. This study aims to evaluate the pattern of lumbrical incursion into the carpal tunnel in various finger positions and determine their extent of presence and relationship with respect to the TCL and to each other in the carpal tunnel.
Materials & Methods: Dissection of 30 fresh frozen cadaveric hands was done to map the lumbrical muscles.
