Abstract

Aim: Carpal tunnel syndrome (CTS) is the most common peripheral mononeuropathy caused by compression of the median nerve at the wrist inside the carpal tunnel. The aim of this study was to investigate the relationship between EMG data and surgical success in patients with CTS who showed a decrease in conduction velocity and prolonged latency in EMG. Thus, it was aimed to link the surgical indications to objective criteria. Patients and Methods: The patients who were diagnosed with carpal tunnel syndrome and underwent surgery between 2013-2018 were evaluated prospectively. In the postoperative 12th month, changes in the median nerve velocity were observed by the EMG controls. Post-operative drowsiness was accepted as a surgical failure. Results: 266 patients (62 males, 204 females) were included in the study. Complaints of 23 patients were continuing. The median motor latency average of the patients who complained was 6,63 msec (min 3,04 - max 11,04), and the message speed was 42,91 m / s (min 36,88 - max 51,8). Median nerve sensory potential was not found in 16 patients, sensory and motor potential was not achieved in 2 patients. Median nerve sensory conduction could not be obtained in 70 of the patients without any complaint, but motor potential was obtained in all of patients. When median motor nerve latency was higher than 4.63 ms, it was found that the patient complaint of drowsiness continued after surgical treatment of CTS. Conclusion: When the motor nerve latans is above 4.63 msn, the chance of success in the surgical treatment of CTS decreases. Performing CTS surgical treatment before these limits may prevent the occurrence of irreversible changes.

Özet

Amaç: Karpal tünel sendromu (KTS), median sinirin el bileğinde karpal tünelde kompresyonu ile oluşan en sık görülen periferik mononöropatisidir. Bu çalışmada EMG’de ileti hızında azalma ve latansta uzama gösteren KTS tanılı hastalarda EMG verilerinin cerrahinin başarısı üstündeki rolü araştırıldı. Böylece cerrahi endikasyonların objektif kriterlere bağlanması amaçlandı. Hastalar ve Yöntem: 2013-2018 yılları arasında elde uyuşma şikayetiyle olan, EMG’de karpal tünel sendromu tanısı almış ve cerrahi uygulanmış hastalar prospektif olarak değerlendirildi. Ameliyat sonrası 12.ayda hastaların şikayetlerinin devam edip etmediği sorgulanarak median sinirdeki ileti hızının değişimi yapılan EMG kontrolleri ile saptandı. Bu verilerle ameliyat öncesi EMG bulguları karşılaştırıldı. Ameliyat sonrası uyuşukluğun devam etmesi cerrahi başarısızlık olarak kabul edildi. Bulgular: Çalışmaya 266 hasta (62 Erkek, 204 Kadın) dahil edildi. Şikayetleri devam eden hasta sayısı 23’tü. Şikayeti devam eden hastaların median motor latans ortalaması 6,63 msn (min 3,04 - max 11,04), ileti hızı ise ortalama 42,91 m/sn (min 36,88 - max 51,8)’di. Şikayetleri devam eden hastaların 16’sında median sinir duyu potansiyeli, 2’sinde hem duyu hem motor potansiyeli elde edilemedi. Şikayeti olmayan hastaların ise 70’inde median sinir duyu iletimi elde edilemezken, tamamında motor potansiyel elde edildi. Median motor sinir latans 4,63 msn’nin üstünde olduğunda KTS cerrahi tedavisinde hastanın uyuşukluk şikayetinin devam ettiği istatistiksel olarak tespit edildi. Sonuç: Motor sinir Latans 4,63 msn’nin üstünde olduğunda KTS cerrahi tedavisinde başarı şansı azalmaktadır. KTS cerrahi tedavisi bu sınırlara gelmeden yapılması geri dönüşümsüz değişikliklerin ortaya çıkmasını engelleyebilir.
