Cubital tunnel syndrome is the second most common nerve entrapment neuropathy. When non-operative treatments fail, surgical intervention is indicated. Although there remains no consensus between simple decompression and anterior transposition, there is a growing recognition of improved clinical outcomes in the latter. Few details of ulnar nerve branches around the elbow are available however and their sacrifice may be necessary to facilitate anterior transposition. Therefore, ten cadaveric upper extremities were dissected to delineate the course and branching pattern of the ulnar nerve around the elbow joint; anterior transposition was also performed in the cadaveric specimens. Digital photographs of the dissection study were analyzed using the Image J package. Results show that distal ulnar nerve branches are distributed more laterally towards the olecranon and may potentially restrict transposition more than has been recognized; proximal branches may also overlap incision lines of such transposition procedures.
A 44-year-old male patient experienced persistent radiating pain from the elbow to the hand following herpes zoster vesicular eruptions three months earlier. His examination met the Budapest Clinical Criteria for Complex Regional Pain Syndrome (CRPS), revealing sensory, motor, vasomotor, and sudomotor signs and symptoms. Despite conservative treatments, the pain persisted.
Introduction: The endoscopic assisted release for cubital tunnel syndrome (CuTS) gained popularity in recent years with unclear long-term results. This study aims to evaluate long term results regarding functional and subjective outcomes after endoscopic assisted release for the CuTS.
Materials And Methods: Thirty one patients who have been treated by endoscopic assisted release for CuTS between 2006 and 2013 were followed up both clinically and with a questionnaire with a mean follow up of 152 months (range 120-204 months).

Background: Hereditary transthyretin amyloidosis (hATTR) is a rare autosomal dominant disease with high clinical variability, influenced by both genotype and the geographic origins of carriers. There is a limited understanding of the Val142Ile and Ser43Asn recognised mutations in Ecuador and Colombia. Therefore, the objective of this study is to describe the neurological and functional characteristics of patients with hATTR associated with the Val142Ile and Ser43Asn mutations, as well as to identify possible differentiating factors between the two mutations.
Background: Understanding peripheral ulnar nerve anatomy is necessary to refine surgical treatment of ulnar nerve injuries. This study topographically mapped the ulnar nerve and its distal branch points from a well-defined surgical landmark and assessed for variations in interfascicular motor arrangement and branch size.
Methods: Fifty-four cadaveric upper extremities were dissected to expose the distal ulnar nerve and its branches (dorsal cutaneous (DCB), volar sensory (VSB), and motor branches).
Background: Pediatric supracondylar humeral fractures present considerable surgical challenges due to the difficulty of achieving proper fracture alignment and stable fixation while avoiding injury to the ulnar nerve. This study assesses the biomechanical performance of a novel Kirschner wire (K-wire) fixation device (KFD), designed to enhance stability and reduce complications linked to traditional K-wire configurations.
Methods: Using finite element analysis (FEA), we evaluated four fixation strategies for treatment of pediatric supracondylar humeral simple transverse fractures: crossed pin fixation, crossed pin fixation with KFD, two lateral pin fixation, and two lateral pin fixation with KFD, under various mechanical loads.
