Abstract

Introduction: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathycaused by the compression of the median nerve in the carpal tunnel in the wrist. In thediagnosis of CTS, neurological examination and electrophysiological studies (EMG) findingsare based primarily. This study was conducted in order to determine how effective magneticresonance imaging examining in the diagnosis and follow-up of patients diagnosed withcarpal tunnel syndrome is.Material and methods: Our research was performed on 21 patients with 23 wrists diagnosedwith CTS with clinical and electrophysiological tests. Magnetic resonance imaging (MRI)was performed preoperatively and postoperatively in 14.2 weeks for the hands of 21 patientsin the anatomical prone position by using a wrist coil. The length and width measurements ofthe sections of the median nerve were proportionalized at three levels (length / width), andflattening ratio of the median nerve, median nerve area, the intensity of the median nerve wereevaluated. All patients was operated by the same surgeon, neurolysis was not applied to anypatient.Results: When the results of the EMG before and after surgery of the study group wereanalyzed, it has been detected that, there was a significant improvement in motor conductionvelocity and sensory conduction time compared to preoperative results. Hand / wrist MRI ofthe study group was compared with the control group, it has been observed that, the arithmeticmean of all measurements, except the ratio of carpal tunnel area / wrist area were greater thanthe control group. The differences in terms of median nerve flattening ratio in the middle anddistal, the distal median nerve area, flexor retinaculum thickness, flexor retinaculum spring,the flexor retinaculum spring ratio were not significant.Conclusion: Electrophysiological studies are the gold standard in the diagnosis of CTS. MRIis an effective method in the evaluation of patients after surgery. It may be used to reveal thecause of failed surgery. MR imaging is an effective method in the diagnosis of patients and inpost-operative follow-up.

Özet

Giriş: Karpal tünel sendromu (KTS) el bileğinde median sinirin karpal tünel içerisindesıkışması sonucu gelişen en yaygın tuzak nöropatisidir. KTS tanısında öncelikle nörolojikmuayene ve elektrofizyolojik inceleme (EMG) bulguları esas alınır. Bu araştırma karpal tünelsendromu tanısı konmuş hastaların magnetik rezonans görüntüleme tetkikinin hastalığıntanısında ve takibinde ne kadar etkili olduğunun tespit edilmesi amacıyla yapılmıştır.Material method: Araştırmamızda klinik ve elektrofizyolojik testlerle KTS tanısı konan 21hasta 23 bilek üzerinde gerçekleştirilmiştir. Preoperatif ve post operatif olarak 14.2 haftada 21hastanın eli anatomik pron pozisyonunda iken el bileği koili kullanılarak magnetik rezonansgörüntüleme(MRG) yapılmıştır. Üç düzeyde median sinirin kesitinin boy ve en ölçülerioranlanarak (boy/en) ve median sinirin yassılaşma oranı, median sinir alanı, median sinirintensitesi, değerlendirilmiştir. Tüm hastalar aynı cerrah tarafından cerrahi uygulanmış, hiçbirhastaya nöroliz uygulanmamıştır.Bulgular: Operasyon öncesi ve sonrası olgu grubunun EMG sonuçlarının incelendiğindemotor ileti hızı ve duysal ileti zamanının operasyon öncesine göre anlamlı oranda düzeldiğisaptanmıştır. Olgu grubunun el/bilek MRG'si kontrol grubu ile karşılaştırılınca karpal tünelalanı/el bilek alanı oranı dışında kalan tüm ölçümlerde aritmetik ortalamanın kontrolgrubundan büyük olduğu görüldü. Orta ve distalde median sinir yassılaşma oranı, distaldemedian sinir alanı, fleksör retinakulum kalınlığı, fleksör retinakulum yaylanması, fleksörretinakulum yaylanma oranın da ise farkın anlamlı olmadığı belirlenmiştir.Sonuç: Elektrofizyolojik çalışmalar KTS tanısını koymakta altın standarttır. MRG hastalarınameliyat sonrası değerlendirilmesinde etkin bir yöntemdir. Başarısız cerrahı nedenini ortayaçıkarmada kullanılabilir. MR tetkiki hastaların tanısı koymada ve post operatif takiplerindeetkili bir yöntemdir.
