The aim of this study was to review the literature on the innervation of the wrist with an emphasis on pathological and therapeutic aspects. The nerves involved in wrist innervation and their mechanoreceptor endings are described. The literature over the past 30 years includes several topics that are still subjects of discussion and debate and require further research.

The lateral antebrachial cutaneous nerve (LACN) is the sensory branch of the musculocutaneous nerve and usually innervates the lateral aspect of the forearm. Isolated lesions are rare, of varied aetiology and generally underdiagnosed. We present a retrospective descriptive study of electromyography performed at the General University Hospital of Castellón in the last 20 years with isolated NCAL lesion.

Background: Deficient shoulder function is a common and exhausting issue in children with obstetric brachial plexus injuries. Even with functioning elbow, wrist, and fingers, upper limb function is markedly disabled by limited shoulder abduction external rotation. Lower trapezius transfer carries many advantages; simple and safe technique, same line of pull as donor; reliable nerve supply (extraplexal from spinal accessory nerve), and not acting on rotation of the shoulder, mostly it will not adversely affect internal rotation range after the transfer.

Background: In motor nerve conduction studies (MNCS), proximal stimulation should give a longer duration and lower amplitude compound muscle action potential (CMAP) due to higher temporal dispersion. Yet the CMAP waveforms at the distal and proximal stimulation sites appear remarkably similar. The objective of this study was to confirm this anomaly and investigate its possible cause by studying the median and ulnar nerves.

Purpose: To evaluate the precise origin of sensory nerves through gross anatomical study of the TFCC, synthesized alongside imaging and histological techniques.
Method: Six cadaveric forearm specimens were obtained to map the course and branches of the ulnar nerve through macrodissection. Immunohistochemical staining targeting PGP 9.
