We describe a patient who presented with dystonia of her small finger secondary to entrapment neuropathy of the ulnar nerve at the elbow. Pre operative electrophysiological studies suggested that the locus of entrapment was located proximal to the medial epicondyle. This was confirmed intraoperatively by the presence of a thickened and prominent arcade of Struthers. Surgical decompression resulted in a rapid and dramatic improvement of the dystonic pattern as well as an improvement in nerve conduction. A review of literature has not revealed any other reports of such a clear cut association between ulnar nerve entrapment and non task-specific focal hand dystonia.

Efficacy and Complications of External Fixator-Assisted Correction in Cubitus Varus Deformity.

Background: Untreated cubitus varus results in cosmetic deformity as well as posterolateral rotatory instability at the elbow if longstanding. French osteotomy with its modifications is the most commonly done osteotomy and relies on a medial intact hinge and these osteotomies fail to address the lateral prominence. Intraoperative fixator assistance to adjust the translation and fine tune the osteotomy is a novel method to address the lateral prominence.

This study assesses differences in median nerve position with or without palmaris longus (PL). We hypothesize that PL presence alters median nerve position, resulting in a greater distance to the skin volar surface, a decreased distance to the radius volar surface, and an increased distance to the flexor carpi radialis (FCR).

Entrapment neuropathies at the elbow are common in clinical practice and require an accurate diagnosis for effective management. Understanding the imaging characteristics of these conditions is essential for confirming diagnoses and identifying underlying causes. Ultrasound serves as the primary imaging modality for evaluating nerve structure and movement, while MRI is superior for detecting muscle denervation.

Objective: Cubital tunnel syndrome is a common peripheral neuropathy of the upper extremity. Anterior transposition of the ulnar nerve is an established surgical treatment option for this condition. This study aimed to introduce a novel musculofascial lengthening technique that uses only a portion of the flexor-pronator muscle mass for submuscular anterior transposition of the ulnar nerve and investigate its clinical outcomes.

Introduction: Carpal tunnel syndrome is a challenging condition when conventional carpal tunnel revision surgery fails to alleviate symptoms. This study aims to assess the outcomes of combining carpal tunnel revision surgery with a synovial wrap for cases of recurrent carpal tunnel syndrome in patients who had adhered median nerve, with a minimum 1-year follow-up.
Patients And Methods: A retrospective analysis was conducted on 10 patients (mean age: 73.
