Aim Of The Study: The short extensor muscle of the toes (extensor digitorum brevis) is innervated by the deep peroneal nerve (DPN) but can also receive innervation from an accessory deep peroneal nerve (ADPN), a branch of the superficial peroneal nerve (SPN).
Patients And Methods: We conducted a systematic electrophysiological study of the DPN and ADPN in 200 healthy subjects (400 legs).
Results: We found the presence of an ADPN in 13.5% of the subjects (8.5% of the legs). On average, ADPN amplitudes and motor potential areas were one-fifth of those for the corresponding DPN. Without this systematic search, most of the ADPN would not have been detected. Comparative study of electrophysiological parameters in patients with and without ADPN showed a significantly higher (P<0.0001) DPN motor potential area ratio (distal/proximal ratio) in subjects without an ADPN.
Conclusion: Even though electrophysiological identification of the ADPN is generally not easy (in simple DPN motor conduction studies), the nerve can sometimes be clinically symptomatic (ankle pain). Evaluation of the DPN motor potential area ratio (distal/proximal ratio) heightens the detection of ADPN.

Glucagon: a potential protective factor against peripheral nerve compromise in patients with type 2 diabetes and obesity.
Diabetol Metab Syndr

Department of Endocrinology, Affiliated Hospital 2 of Nantong University, and First People's Hospital of Nantong City, No.666 Shengli Road, Nantong, 226001, China.
Background: Increased glucagon levels are now recognized as a pathophysiological adaptation to counteract overnutrition in type 2 diabetes (T2D). This study aimed to elucidate the role of glucagon in peripheral nerve function in patients with T2D with different body mass indices (BMIs).
Methods: We consecutively enrolled 174 individuals with T2D and obesity (T2D/OB, BMI ≥ 28 kg/m), and 480 individuals with T2D and nonobesity (T2D/non-OB, BMI < 28 kg/m), all of whom underwent oral glucose tolerance tests to determine the area under the curve for glucagon (AUC).

Department of Orthopaedic Surgery, Brigham and Women's Hospital, Boston, MA, United States.
Purpose: The popularity of minimally invasive (MIS) foot surgery continues to grow. However, it comes with certain limitations that present notable challenges. One significant hurdle is the absence of direct visualization of neurovascular structures and tendons.

Background: The development of new biomarkers is essential to improve diagnostic accuracy and guide treatment decisions in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). The aim of this study was to investigate the utility of the serum neurofilament light chain (sNfL) level as a marker for disability and response to immunomodulatory treatment in patients with CIDP.
Methods: This prospective, single-center, observational study included 38 patients with CIDP: 19 treatment-naive (CIDP-I) patients assessed before and after the initiation of immunomodulatory therapy and 19 stable patients on maintenance immunoglobulins (CIDP-M).
Imaging on the painful and compressed nerve: lower extremity.
Int Orthop
January 2025
Aspetar Orthopedic and Sports Medicine Hospital, Doha, Qatar.
Entrapment neuropathies of the lower extremity are often underdiagnosed due to limitations in clinical examination and electrophysiological testing. Advanced imaging techniques, particularly MR neurography and high-resolution ultrasonography (US), have significantly improved the evaluation and diagnosis of these conditions by enabling precise visualization of nerves and their surrounding anatomical structures. This review focuses on the imaging features of compressive neuropathies affecting the lumbosacral plexus and its branches, including the femoral, obturator, sciatic, common peroneal, and tibial nerves.

Department of Rehabilitation, Tianjin Hospital, Tianjin, China.
Background: Injuries to the common peroneal nerve often result in significant sensory and motor function loss, severely affecting patients' quality of life. Although existing treatments, including medication and surgery, provide some degree of efficacy, their effectiveness is limited by factors such as tolerance and adverse side effects.
Methods: This study aims to evaluate the effects of a 4-week regimen of mirror therapy combined with neuromuscular electrical stimulation on lower limb function, muscle strength, and sensation in patients with common peroneal nerve injuries.
