Introduction: There exist conflicting electrodiagnostic reports between diagnosing mild carpal tunnel syndrome (CTS) and normal results, depending on the interpretation methods used by electrodiagnosticians. This underscores the necessity for precise clinical guidelines. This study aims to assess how the variation between mild and normal electrophysiological reports impacts (1) subsequent clinical outcomes in patients diagnosed with CTS and (2) physicians' decision-making.

This study aimed to compare the fascicular anatomy of upper limb nerves visualized using in situ high-resolution ultrasound (HRUS) with ex vivo imaging modalities, namely, magnetic resonance microscopy (MRM), histological cross-sections (HCS), and optical projection tomography (OPT). The median, ulnar, and superficial branch of radial nerve (n = 41) were visualized in 14 cadaveric upper limbs using 22-MHz HRUS. Subsequently, the nerves were excised, imaged with different microscopic techniques, and their morphometric properties were compared.

Introduction: Surgical treatment of ulnar tunnel syndrome is controversial, with no consensus on the ideal procedure. Nevertheless, in-situ decompression seems to provide faster recovery with less morbidity than neurolysis-transposition. The aim of this retrospective study was to validate a new percutaneous technique using ultrasonography.

Long-term follow-up study of Kudo Type-5 elbow prosthesis in patients with rheumatoid arthritis: minimum 10-year clinical outcomes.

J Shoulder Elbow Surg

December 2024

Department of Orthopaedic Surgery, Faculty of Medicine, The University of Tokyo, 7-3-1 Hongo, Bunkyo-ku, Tokyo, 113-8655, Japan. Electronic address:

Objectives: Rheumatoid arthritis often leads to debilitating damage in the elbow joint, which may require total elbow arthroplasty (TEA). The Kudo TEA is one of the unlinked type prostheses with reportedly favorable outcomes. However, there is limited information available regarding its long-term performance.

Rare bilateral vascular variations of the upper limb: a cadaveric case study.

J Cardiothorac Surg

December 2024

Centre for Human Anatomy Education, Department of Anatomy and Developmental Biology, Biomedical Discovery Institute, Faculty of Medicine, Nursing and Health Sciences, Monash University, Clayton, Australia.

Arterial variations in the upper limb are of significant clinical importance, especially in procedures such as venepunctures, coronary artery bypass grafts, trauma reconstructive surgeries, brachial plexus nerve blocks, and breast reconstructions. This report presents previously undocumented arterial variations in the upper limbs in a 95-year-old female cadaveric donor. We observed bilateral superficial ulnar arteries originating at the cubital fossa, deviating from the previously reported origin at the proximal brachial artery.
