What the literature leaves open

  • Although a sensitivity analysis confirmed the stability of our main pooled estimate, data from other regions remain scarce. An assessment of publication bias was inconclusive, as funnel plot asymmetry is likely a product of both high clinical heterogeneity and potential publication bias.

    Anatomical variation of the sciatic nerve division in the cadaver studies: a systematic review and meta-analysis · 2026 · DOI

  • There is a need to understand the biomechanical and morphological foundations of cubital tunnel syndrome. The pathogenesis of cubital tunnel syndrome is not fully understood.

  • One challenge is the limited size of the dataset, which requires careful selection of the backbone architecture. Another challenge is the variability encountered in ultrasound acquisition, including changes in transducer angle, patient positioning, and tissue deformation. The study also identifies the need for further evaluation on abnormal nerves and expansion of the dataset to include more patients and nerve types.

    Ultrasound imaging of small peripheral nerves – a primer for radiologists · 2026 · DOI

  • Electrophysiology provides only functional information and often fails to identify underlying anatomical causes. There is a need for a structured ultrasound protocol for assessing the common peroneal nerve.

    Ultrasound of the common peroneal nerve at the knee: a structured scanning protocol · 2026 · DOI

  • Meralgia paresthetica remains a frequently overlooked mononeuropathy. There is a need for a more comprehensive evaluation of patients with meralgia paresthetica. Current imaging techniques have limitations in evaluating the LFCN.

    Meralgia paresthetica: from qualitative ultrasound assessment to quantitative multimodality imaging · 2026 · DOI

  • Variations in ulnar nerve branching patterns have been a subject of investigation among several researchers. There is a need to understand the morphology of the ulnar nerve in the forearm and hand, including its variations.

    Morphology of the Ulnar Nerve in the Forearm and Hand, Including Its Variations · 2026 · DOI

  • Epidemiological and electrophysiological data from Sub-Saharan Africa remain scarce. No published study has specifically described the CTS profile in the local setting.

    Clinical and Electrophysiological Profile of Carpal Tunnel Syndrome in a Tertiary University Hospital in Senegal: A Descriptive and Analytical Study · 2026 · DOI

  • Delayed diagnosis due to lack of awareness of Hansen's disease as a cause of peripheral neuropathy. Irreversible neurological deficits if left untreated. Limited access to diagnostic and treatment facilities in endemic areas.

    Chronic ulnar nerve thickening with elbow mass: Imaging features suggestive of Hansen’s disease · 2026 · DOI

  • However, balanced against the higher revision rate and higher costs associated with ECTR, the tradeoff remains unclear, as reflected in divergent guideline recommendations.

    A Mechanism-Based Classification and Review of Endoscopic and Ultrasound-Guided Carpal Tunnel Release · 2026 · DOI

  • Most comparative trials use open or mini‑open CTR as the control; head‑to‑head tri‑ als between ECTR and UGCTR are limited to a single prospective propensity‑matched cohort, with no randomized head‑to‑head data and none comparing the different UGCTR mechanisms.

    A Mechanism-Based Classification and Review of Endoscopic and Ultrasound-Guided Carpal Tunnel Release · 2026 · DOI

  • The effects of hand nerve repair on digit maps in humans are not well understood. The relationship between altered digit maps and functional impairments is not well established. The study aims to address these gaps in knowledge.

    Cutting a nerve of the hand alters the organization of digit maps in primary somatosensory cortex · 2026 · DOI

  • The occurrence of such anterior or medial ulnar nerve variants relative to the medial epicondyle is rare but may be underreported because only a small subset of patients undergo surgeries like cubital tunnel release, where this aberrant anatomy would be identified.

    Surgical implications of an anteriorly positioned ulnar nerve of unknown etiology at the elbow: illustrative case · 2026 · DOI

  • The diagnosis of piriformis syndrome remains contentious in the absence of a universally accepted gold-standard test. The study has a small sample size of three patients.
