The association of trapeziectomy with ligamentoplasty is a simple treatment for osteoarthritis at the base of the thumb. Here we present the long-term results of a technique that creates a "hammock" under the first metacarpal bone using the Abductor Pollicis Longus tendon. This paper reports the results of treatment by this operation of 60 thumbs in 50 patients, including 13 men and 37 women of average age 60 (46-75) years. Thirty thumbs presented with severe pain and 30 with moderate pain. At final follow-up, 47 thumbs (78%) had experienced dramatic relief of pain following the procedure, 12 (20%) thumbs still had mild pain and one (2%) thumb had severe pain. No patients needed revision.

Objective: To investigate motor axonal excitability in multifocal motor neuropathy (MMN) associated with involuntary muscle activity.
Methods: Two MMN patients with continuous involuntary finger movements (MMNifm) were compared to 11 patients without movements (MMNnfm). Clinical examination, EMG of the abductor pollicis brevis muscle, nerve conduction studies, motor unit number estimation, excitability studies, and mathematical modeling were conducted in the patients with MMN and compared to controls.

Mouse models of amyotrophic lateral sclerosis (ALS) enable testing of novel therapeutic interventions. However, treatments that have extended survival in mice have often failed to translate into human benefit in clinical trials. Compound muscle action potentials (CMAPs) are a simple neurophysiological test that measures the summation of muscle fiber depolarization in response to maximal stimulation of the innervating nerve.

Surgeons use anatomical landmarks like the scaphoid tubercle, pisiform, trapezial tubercle and hook of hamate, along with Kaplan cardinal line (KCL) to avoid injury to the recurrent motor branch (RMB) of the median nerve during carpal tunnel release. The presence of transverse muscle fibres (TMF) overlying the transverse carpal ligament (TCL) may suggest proximity of the RMB, but their anatomical relationship is unclear. In this study, we evaluated the accuracy of anatomical landmarks to the RMB, TMF origin and insertion, and examined the relationship between TMF presence and RMB running patterns.

Carpal tunnel syndrome (CTS) due to amyloid deposition was reported to precede fatal cardiac amyloidosis by several years. Although nerve conduction study (NCS) supports CTS diagnosis, the incidence of positive amyloid deposition in electrophysiologically proven CTS is unclear. We retrospectively analysed the demographic data including age, gender, bilateral hand involvement, amyloid deposition and NCS results, of 111 consecutive CTS patients with postoperative symptom improvement (mean 71.

Background: Quantifying the biomechanical properties of the thenar muscle can provide valuable insight into hand assessment methods.
Purpose: This study aimed to examine the reliability of myotonometer measurements in determining the biomechanical properties (tone, stiffness and elasticity) of thenar muscles in healthy individuals and explore sex-based variations. Additionally, it assessed the relationship between pinch strength and these properties.
