Carpal Tunnel Syndrome in the Non-Dominant Hand

Amaç: Karpal tünel sendromu (KTS) median sinirin el bileği seviyesinde, karpal tünel içinde farklı nedenlere bağlı olarak, basıya maruz kalması sonucu gelişen, üst ekstremitenin en sık görülen periferik bir nöropatisidir.Ülkemizde yapılan bir çalışmada sağ el tercihi oranı %67,5, sol el tercih oranı %31,9 ve her iki eli de kullanabilme oranı %1,1 olarak saptanmıştır.Karpal tünel sendromunun baskın olan elde daha sık görüldüğü bilinmektedir.Bu çalışmada izole baskın olmayan elde veya daha belirgin derecede KTS saptanan olguların demografik ve risk faktörleriyle ilişkisi araştırılmıştır. Materyal ve Metot: Ocak 2016- ocak 2020 tarihleri arasında, Samsun Eğitim veAraştırma Hastanesi elektofizyoloji laboratuvarına KTS ön tanısıyla yönlendirilen ve KTS saptanan olgular ardışık olarak çalışmaya dahil edilmiş ve retrospektif olarak incelenmiştir. Bulgular: Çalışmaya KTS ön tanısıyla EMG laboratuvarına yönlendirilen ardışık 3304 hasta alındı. Hastaların 439 kişide KTS saptanmadığı için çalışma dışı bırakılarak 2865 olgu değerlendirildi. İki taraflı KTS olgularının %57,1’inde baskın elde daha belirgin, %8,5’inde baskın olmayan elinde daha belirgin KTS saptanmıştır.Her iki el tercihi olan olguların %60’ında sağ, %40’ında sol elde daha belirgin KTS saptanmıştır. Sonuç: Karpal tünel sendromu saptanan, sağ ve sol el tercihli hastaların yaş, cinsiyet, demografik ve sinir iletim incelemeleri açısından istatistiksel olarak anlamlı fark bulunmadı.Aim: Carpal tunnel syndrome (CTS) is the most common peripheral neuropathy of the upper extremity, which develops as a result of exposure of the median nerve at the level of the wrist, within the wrist canal due to different reasons. In a study conducted in our country, the rate of right-handedness was 67.5%, the rate of left-handedness was 31.9%, and the rate of using both hands was 1.1%. In this study, our aim is to examine the rates of isolated and/or bilateral CTS in the non-dominant hand, which is more prominent in this wrist. Materials and Methods: Between January 2016 and January 2020, the cases who were referred to Samsun Training and Research Hospital electrophysiology laboratory with the preliminary diagnosis of CTS and who were found to have CTS were included in the study consecutively and analyzed retrospectively. Annet Hand Preference Questionnaire” was applied. Results: A total of 3304 consecutive patients referred to the EMG laboratory with a preliminary diagnosis of CTS were included in the study. Since CTS was not detected in 439 patients, 2865 cases were evaluated by excluding them from the study. Of 2810 right-handed patients; There were 1874 women (66.7%) and 936 (33.3%) men, with a mean age of 45.1±1.7 and 48.5±0.7, respectively. There were 35 (1.2%) left hand dominant patients. There was no statistically significant difference between the age, gender and demographic data of the right and left hand dominant patients. Conclusion: CTS was detected only in the right hand of 2100 (74.7%) patients with right-handed preference. CTS was more prominent in the dominant hand in 18% of bilateral CTS cases, and more prominent in the non-dominant hand in 5.4%. Although it is one of the few studies on hand dominance in the literature, the high number of patients in the article increases the value of the article. As in other studies, carpal tunnel syndrome is more prominent in the dominant hand
