GAMBARAN KLINIS DAN ELEKTRONEUROGRAFI NEUROPATI ULNA DISTAL PADA PASIEN SINDROM TEROWONGAN KARPAL DI RUMAH SAKIT CIPTO MANGUNKUSUMO

Introduction: Several studies have been reported in ulnar involvement carpal tunnel syndrome (CTS). There was also some researches CTS in Indonesia, but there is no study showed correlation between CTS and ulnar neuropathy at the wrist. Therefore this study can be a preliminary data to explore ulnar involvement in CTS patients. Aim: To determine the prevalence of ulnar neuropathy at the wrist based on clinical features and electroneurography in CTS patients. Method: This is a cross-sectional study in electroneurography laboratorium of Neurology Departement of Cipto Mangunkusumo Hospital involving CTS patients. Results: Of 32 patients and 52 hands, we found ulnar abnormality in form digiti IV-V sensory disturbance in 36 hands (62,1%). Motor and sensory amplitude decrement found in 28 (47,5%) and 23 (39,6%) hands. Ulnar neuropathy at the wrist in CTS based on electroneurography was found in 2 (3,45%) hands. Sensory disturbance was found more dominant in group of age 41-60 years old in 31 (86,1%) hands (p=0,3). There is no significance correlation between repetitive movement pattern and CTS severity with sensory disturbance (p = 0,66 and p = 0,07) Conclusion: The prevalence of digit IV-V sensory symptoms in this study was 62,1%. Distal ulnar neuropathy prevalence in this study was 3,45%.
