Abstract

Amaç: Ulnar sinir seyri boyunca çeşitli noktalarda basıya hassastır ve özellikle dirsek bölgesi travmaya en açık alandır. Bu çalışmada, dirsekte ulnar nöropati ile ilişkili faktörler, lezyonun lateralitesi, elektromiyografi (EMG) ve manyetik rezonans görüntüleme (MRG) bulguları ile bunların üst ekstremite fonksiyonlarına etkileri değerlendirildi.
Gereç ve Yöntemler: Ekim 2023-Nisan 2025 arasında ulnar nöropati ön tanısıyla EMG yapılan 18-75 yaş arası 52 hasta retrospektif olarak incelendi. Demografik özellikler, komorbiditeler, dominant el, semptom süresi, yaşam tarzı faktörleri, eşlik eden tuzak nöropatiler ve Kısaltılmış Kol, Omuz ve El Engellilik Anketi (Quick-DASH) skorları kaydedildi. Ulnar sinirin sıkıştığı dirsek MRG ile değerlendirildi. MRG’de sinyal yoğunluğu ve boyut artışı, intranöral/ekstranöral lezyon ve efüzyon varlığı kaydedildi.
Bulgular: Katılımcıların 21’i (%40,4) erkek, 31’i (%59,6) kadındı; %88,5’inde sağ el dominanttı. 23 hastada (%44,2) 2 saatten uzun telefon kullanımı, 16’sında (%30,8) dirseği masaya yaslama alışkanlığı vardı. Ulnar nöropati 21 hastada (%40,4) sağ, 12 hastada (%23,1) bilateraldi. Nöropati şiddeti 28 hastada (%53,8) hafif, 7 hastada (%13,5) ağırdı. Ortalama Quick-DASH skoru 31,5±26,9 idi. 23 hastada (%44,2) karpal tünel sendromu eşlik etmekteydi. Orta-ağır ulnar tuzaklanması olan hastalarda MRG bulguları anlamlı derecede daha fazlaydı (p=0,002).
Sonuç: Ulnar sinir tuzaklanmasının erken tanısında dikkatli muayene, elektrodiagnostik testler ve görüntüleme yöntemleri birlikte kullanılmalıdır. Yaşam tarzı faktörlerinin modifiye edilmesi semptomların azalmasına ve progresyonun önlenmesine katkı sağlayabilir.

Evaluation of Factors Associated with Ulnar Neuropathy at the Elbow and Electromyography Findings

Abstract

Aim: The ulnar nerve is vulnerable to compression along its course, particularly at the elbow. This study aimed to evaluate factors associated with ulnar neuropathy at the elbow, lesion laterality, electromyography (EMG) and magnetic resonance imaging (MRI) findings, and their effects on upper extremity function.
Material and Methods: Medical records of 52 patients aged 18–75 who underwent EMG with suspected ulnar neuropathy between October 2023 and April 2025 were retrospectively reviewed. Demographics, comorbidities, hand dominance, symptom duration, lifestyle factors, coexisting entrapment neuropathies, and Quick Disabilities of the Arm, Shoulder and Hand (Quick-DASH) scores were recorded. MRI findings of the affected elbow included increased nerve signal/size, intraneural or extraneural lesions, and effusion.
Results: Of 52 patients, 21 (40.4%) were male and 31 (59.6%) female; 88.5% had right-hand dominance. Prolonged mobile phone use (>2 hours) was reported in 23 patients (44.2%), and leaning on the elbow in 16 (30.8%). Ulnar neuropathy was right-sided in 21 (40.4%) and bilateral in 12 (23.1%). Neuropathy severity was mild in 28 (53.8%) and severe in 7 (13.5%). The mean Quick-DASH score was 31.5±26.9. Coexisting carpal tunnel syndrome was present in 23 patients (44.2%), mostly moderate in severity. MRI findings were significantly more frequent in elbows with moderate to severe entrapment (p=0.002).
Conclusion: Careful neurological examination, electrodiagnostic tests, and imaging are essential for early detection of ulnar nerve entrapment. Lifestyle modifications may help reduce symptoms and prevent progression.
