SUMMARY: Carpal tunnel syndrome (CTS) is the most common nerve entrapment disorder. It is characterized by pain, paraesthesia and, ultimately, muscle wasting of the hand. The purpose of this study was to evaluate the prevalence of CTS among haemodialysis patients both clinically and with the use of electromyography (EMG). Fifty-five dialysis patients on regular haemodialysis treatment were included. There were 34 (62%) female and 21 (38%) male patients. The mean age was 47.3 ± 13.7 years. The mean age at commencement of dialysis was 44.4 ± 14.5 years. The mean duration on dialysis was 37 months. Twenty-two patients (40.8%) showed normal examination and normal EMG findings. Thirty-two patients (59.2%) had either abnormal EMG findings or positive physical signs or both. Further analysis of these 32 patients indicated that 13 patients (24%) had abnormal EMG finding compatible with the diagnosis of CTS and there were abnormal clinical features in 26 patients (48%) (seven patients with positive EMG findings and 19 patients with negative EMG studies). There was not a good correlation between EMG and the clinical examination. There was a statistically significant positive correlation between the finding of abnormal EMG suggesting CTS and the duration on dialysis, with increasing prevalence observed in patients treated for more than 5 years (P = 0.039). CTS was also diagnosed by EMG in 18% of patients remaining on dialysis for less than 5 years. This study revealed the high prevalence of CTS in dialysis patients and emphasizes the importance of EMG studies in the detection of early cases of CTS. It also provides quantitative data for timely surgical intervention before irreversible changes and during the follow-up of patients after decompression of the median nerve. [ABSTRACT FROM AUTHOR] |
