“…Therefore, compression of the ulnar nerve at the wrist may explain the ulnar spread of sensory symptoms in mild/moderate CTS patients. The present results are similar to those of Yemisci et al (2011). Ablove et al (1996) report that the volume and pressure in Guyon's canal are elevated in CTS patients and that spontaneous relief of ulnar nerve symptoms occurs after isolated carpal tunnel release.…”

ABSTRACT. Many carpal tunnel syndrome (CTS) patients have symptoms in both the median and ulnar digits more frequently than in the median digits alone. This is possibly because of close anatomical contiguity of the carpal tunnel and Guyon's canal, and the high pressure may also affect the latter, causing indirect compression of ulnar nerve fibers. Thus, we evaluated the functional status of the ulnar nerve in patients with CTS in order to investigate the relationship between ulnar nerve impairment and sensory symptoms of the ulnar territory. Electrophysiological studies were conducted in CTS patients and healthy controls. CTS patients were divided into the mild/moderate group and severe group; they were further divided into the symptomatic and asymptomatic subgroups according to the sensory symptom of the fifth digit region. The findings suggest that CTS patients could have coexisting ulnar nerve wrist entrapments that might exacerbate the severity of CTS. Sensory impairment in the ulnar territory was observed more frequently in the mild/moderate stage of CTS, which is associated with ulnar nerve involvement. These findings also suggest that damage Ulnar nerve in carpal tunnel syndrome to the ulnar nerve fibers caused by compression forces in Guyon's canal may underlie the ulnar spread of symptoms in CTS.

“…However, there was no significant positive correlation between MDLu and MDLm, which was also noted by Ginanneschi et al [28]. Moreover, contrary to what has been reported in other studies [3,10,27,28], we did not detect correlations, neither positive nor negative, between other parameters, especially SCVu and SVCm [28], ASPu and SCVm [10], ASPu and MDLm [3,10,28], SCVu and MDLm [27,28] and sensory distal latency of ulnar nerve (SDLu) and MDLm [27].…”

“…Similar results were noted in some other studies, but were statistically significant [27,32]. Furthermore, when comparing the averages of these parameters in each group ("whole hand" and "limited to median nerve territory" paresthesias) with the averages of the correspondent parameters in "healthy hands" group, statistically significant differences were found.…”

“…Similar results were found by other authors both for sensory parameters of the ulnar nerve [3,10,27] and MDLu [10,28]. However, Azmy et al [30] found a non-significant difference between APSu averages of healthy and affected hands.…”
