Summary: This study aimed to establish normative data for cross sectional area (CSA) measurements of the median and ulnar nerves in children using ultrasound. The CSA measurements of the nerves were found to correlate with patient age and height.

Summary: The article provides a comprehensive review of functional recovery in the rat median nerve model. It highlights the impact of different types of nerve injuries on the onset and speed of recovery and recommends the use of additional tests in conjunction with the grasping test. Careful planning of repetitive examinations is necessary to ensure valid and reliable data.

Summary: The study demonstrates that computerized gait analysis is a valid and feasible method for evaluating functional recovery following autograft repair of the rat median nerve. Parameters such as Print Area, Duty Cycle, and Stand Index were identified for assessing nerve regeneration. External paw rotation was also identified as a valid parameter for evaluating motor reinnervation.

Summary: Ulnar nerve repetitive nerve stimulation (RNS) has traditionally been used to evaluate myasthenia gravis (MG) but has lower diagnostic sensitivity compared to median nerve RNS. This study directly compared the diagnostic yields of median and ulnar nerve RNS in patients with generalized MG, finding that median nerve RNS had superior diagnostic sensitivity for mild generalized MG.

Summary: Functional Near-Infrared Spectroscopy (fNIRS) is a non-invasive optical technique that measures cerebral hemodynamics across multiple regions of interest, and thereby characterises brain functional activation. Since its first description in 1993, fNIRS has undergone substantial developments in hardware, analysis techniques, and applications. This technique has significantly enhanced our understanding in diverse areas of neuroscience research and is being applied in neurodevelopment, cognitive neuroscience, psychiatric disorders, neurodegenerative conditions, and brain injury management in intensive care settings.

Summary: The study confirmed differences in physiological sensory perception between the median and ulnar nerves, with the median nerve being more sensitive to temperature stimulation and less sensitive to pain-inducing temperature stimuli compared to the ulnar nerve. Vibratory limits did not significantly differ between nerves and subgroups.

Summary: This study reviews the surgical procedures and functional results of distal sensory nerve transfers for ulnar nerve lesions above the wrist. Sensation recovery was assessed using the British Medical Research Council scale, and excellent results were reported for each technique in the targeted territory.

Summary: Anterior interosseous nerve to ulnar motor nerve supercharged end-to-side (SETS) nerve transfer, known as a super turbocharged end-to-side (STETS) procedure, redirects axons from the abductor digiti minimi (ADM) muscle to enhance innervation of critical intrinsic muscles in severe ulnar neuropathy. The STETS technique may optimize outcomes without additional patient morbidity by directing the maximum number of nerve fibers to the most critical target.

Summary: This study aimed to present functional outcomes of carpal tunnel release surgery in mucopolysaccharidosis patients. The results showed improvements in handling small and large objects post-surgery, but it is inconclusive whether the surgery alone was responsible for these benefits. Better designed studies are needed to draw more definitive conclusions.

Summary: This study assessed the relationship between ultrasonographic hand muscle thickness measurements and hand muscle strength in patients who underwent median or ulnar nerve reconstruction. Moderate to highly correlations were observed between different muscle thickness measurements and pinch and handgrip strengths in both nerve groups. Sonographic measurements of intrinsic hand muscle thickness may be a useful tool for the assessment and follow-up of patients with median or ulnar nerve injury.

Summary: This study identified and outlined a reliable anatomical landmark, the ulnar insertion of the brachialis muscle, to protect the median nerve during elbow surgery. The research demonstrated that elbow flexion and neutral forearm position significantly increase safety margins between the two structures, suggesting potential modifications to medial elbow approaches described previously.

Summary: This study compared the functional outcomes of surgical intervention for ulnar tunnel syndrome (UTS) patients with different etiologies. The results showed that ulnar tunnel release can improve the outcome of patients regardless of the etiology, especially in patients with trauma-induced UTS.

Summary: Nerve guide conduits (NGCs) have been explored as advanced tools for peripheral nerve injury treatment, with 3D printing technologies showing great potential in fabricating functional NGCs. Various printing methods and construction strategies for functional NGCs are discussed in this review, highlighting the challenges and prospects for their development.

Summary: This study anatomically dissected the cutaneous nerve branches of the median and ulnar nerves in the palm. The results revealed three groups of nerve branches with different distributions, including a proximal row, a distal row, and a metacarpophalangeal group. The palm of the hand was consistently innervated by long branches originating proximal to the palmar arch and shorter branches originating distal to the palmar arch.
