الوصف: The ulnar nerve compression neuropathy commonly occurs around the elbow; however, focal compression or injury can also occur at the wrist, axilla, or neck involving the roots of the brachial plexus. Ulnar neuropathy at the wrist is caused by the compression of the ulnar nerve within Guyon’s canal or distal to it, often referred to as ‘ulnar tunnel syndrome.’ It can manifest as mixed, pure sensory, or pure motor neuropathy depending on the specific site of compression and the branches involved. This case report of 21 years old male patient, a college student, discusses the clinical and electrodiagnostic features of a case involving unilateral isolated pure motor neuropathy of the ulnar nerve. The onset of the case was insidious and subacute, characterised by painless and non-progressive symptoms with no history of trauma or injury to the affected limb. The Nerve Conduction Studies (NCS) were conducted, indicating probable compression of the deep motor branch of the ulnar nerve distal to the wrist. The patient was subsequently referred for highresolution Ultrasonography (USG) or Magnetic Resonance Imaging (MRI). Cases of ulnar neuropathy at the wrist are quite rare, and there is limited literature available on this topic.

الوصف: Introduction: The Martin-Gruber anastomosis is a median-ulnar nerve communication in the upper part of the forearm. This anastomosis is classified into four types. Aim: To determine the incidence and morphometry of the Martin-Gruber anastomosis and recognise its surgical implications in the South Indian population. Materials and Methods: This cross-sectional study was conducted on 60 cadaveric upper limb specimens obtained from the Department of Anatomy, Rajarajeswari Medical College and Hospital, Bengaluru, Karnataka, India between November 2022 and March 2023. The median and ulnar nerves were traced, and the Martin-Gruber anastomosis was identified and documented. The classification devised by Nakashima T was used in present study. The distance from the medial epicondyle of the humerus to the point of anastomosis on the ulnar nerve was measured using Vernier calipers. The data were analysed using the statistical software Stastistical Packages for the Social Sciences (SPSS) version 23.0. Categorical variables were expressed as frequency and percentage, while continuous data were expressed as mean and standard deviation. Results: The Martin-Gruber anastomosis was observed in 11 out of 60 upper limb specimens (18.33%). Type I anastomosis was observed in 3 specimens (27.27%), Type II in 2 specimens (18.18%), and Type III in 6 specimens (54.4%). Type IV was not documented in present study. The distance from the location of the anastomosis on the ulnar nerve to the medial epicondyle of the humerus ranged from 2.2 cm to 13.2 cm, with an average of 3.5 cm. Conclusion: The findings of present study might be useful for neurosurgeons during nerve transfer techniques for chronic ulnar neuropathy, which is seen in the general population as well as athletes.

الوصف: The common neuropathy Cubital Tunnel Syndrome (CuTS) causes sensory impairment. Numerous patients also exhibit muscle atrophy as a symptom of severe and persistent nerve damage, which typically portends a poor prognosis. In the majority of individuals with minor nerve dysfunction, nonsurgical treatment aimed at reducing both compression and traction on the ulnar nerve at the elbow is successful. The optimum care for a patient with this pathology requires prompt and accurate evaluation, diagnosis, and testing, as well as evidence-based therapy choices. The goal of this review article was to offer an updated summary of the most recent research on the results of several surgical procedures for CuTS. A clinician must use the available information to develop a diagnosis and treatment plan that are unique to the patient. The most effective surgical methods for CuTS need to be discovered through more in-depth scientific investigation.

Post-operative complications were compared between subjects who underwent the procedure with regional versus general anesthesia.Results: Ninety-one ulnar nerve in situ decompressions were included in the study, which were performed under regional anesthesia in 55 and general anesthesia in 36 cases. The occurrence of post-operative complications was not significantly different between patients who received regional (n = 7) anesthesia and general (n = 8) anesthesia. None of the complications were directly attributed to the type of anesthesia administered. The change in pre- and post-operative McGowan scores were not significantly different between anesthesia groups (p = 0.81).Conclusion: In situ ulnar nerve decompression at the cubital tunnel under regional anesthesia does not result in increased post-operative complications compared to those surgeries performed under general anesthesia. In situ ulnar nerve decompression performed under regional anesthesia is a safe and reliable option for patients who wish to avoid general anesthesia.Level of Evidence: III.Keywords: cubital tunnel, regional anesthesia, ulnar neuropathy

الوصف: Variations are inherent feature of the intricate brachial plexus. They can be at the level of origin, the course, or the innervation pattern of each peripheral nerve. Knowledge of the various described variations can be worthwhile during the routine hand surgery procedures. We present a case of an elderly patient with anomalous intramuscular course of the ulnar nerve presenting with ulnar neuropathy at the elbow. Level of Evidence: IV.

الوصف: Background: Ulnar neuropathy at the elbow is a common presenting disorder in neuromuscular medicine. Patients suffer from paresthesia in the 4/5 finger, pain at the elbow, and weakness and atrophy in advanced cases. Objective: This study aimed to find the incidence of ulnar nerve subluxation in patients with ulnar neuropathy at the elbow. Materials and Methods: This is a case-control study conducted in Al-Sadiq teaching hospital at the period of January 2018–August 2022. It included 84 patients diagnosed with ulnar neuropathy at the elbow by history, clinical examination and electrodiagnostic testing. All patients and control undergo ultrasonographic examination by high-resolution ultrasound looking for ulnar nerve cross-sectional area at 3 points: (1) 7 cm proximal to medial epicondyle, (2) at the medial epicondyle, and (3) at the cubital tunnel 2-3 cm distal to medial epicondyle. Also, dynamic ultrasonographic examination were done looking for subluxation of ulnar nerve behind medial epicondyle during elbow flexion. If ulnar nerve move on the top of medial epicondyle it is considered partial and when it dislocates anteriorly beyond the tip of medial epicondyle it is considered complete subluxation.

الوصف: Purpose: This study aims to investigate the ulnar-median mixed nerve latency difference (U-MLD) recorded from the medial aspect of the arm both in patients with ulnar neuropathy at the elbow (UNE) and in healthy individuals and thus to assist in the diagnosis of UNE. Materials and Methods: Twenty-nine patients meeting electrophysiological criteria defined by the American Association of Neuromuscular and Electrodiagnostic Medicine for diagnosis of UNE, and 50 healthy individuals were included in the study retrospectively. All participants' data were evaluated, such as median/ulnar motor and sensory response, U-MLD and the percentage of ulnar mixed nerve response amplitude difference between sides. Results: The U-MLD was significantly higher in patients with UNE than in the control group (1.78 ± 0.64 ms vs. 0.6 ± 0.22 ms, P = 0.000). The percentage of the ulnar mixed nerve response amplitude loss was significantly higher in the patient group compared to the control group (43.9% ± 30.3% vs. 21.4% ± 12.2%, P = 0.018). The U-MLD was significantly higher in the patients with amplitude loss ≥50%, and the ulnar mixed nerve response amplitude loss was ≥50% in all five patients with the ulnar sensory nerve action potential pathology. Conclusions: U-MLD is higher in patients with UNE; it can provide additional data in mild cases regarding the diagnosis of UNE, especially. Furthermore, the criterion that the ulnar mixed nerve response amplitude difference between the sides ≥50% suggests that it can be used to evaluate the severity of UNE.
