Dördüncü parmak median-ulnar duyusal sinir latans fark testinin Karpal Tünel Sendromu derecelendirmesindeki değeri

Year 2016, Issue: 1, 11 - 15, 01.04.2016

Abstract

Amaç: Dördüncü parmak median-ulnar duyusal sinir latans fark testi, özellikle başlangıç düzeyindeki karpal
tünel sendromu olgularını saptamada sık kullanılan bir yöntemdir. Bu çalışmada dördüncü parmak median-ulnar
duyusal sinir latans fark testinin, karpal tünel sendromu derecelendirmesindeki değerini göstermek ve 4. parmak
median-ulnar duyusal sinir mukayeseli çalışmayı gerçekleştirmek için 2. parmak median duysal sinir latansının
hangi değerden yüksek olması gerektiğini belirlemek amaçlanmıştır.
Gereç ve yöntem: Rutin sinir iletim çalışmaları normal ve dördüncü parmak median-ulnar duyusal sinir latans
farkı 0.5 msn ve üzerinde ise çok hafif KTS, sadece median sinir duyusal latans uzaması (3.5 ms üzerinde)
varsa hafif KTS, median duyusal latans uzamasına ek olarak, median duyusal amplitüd düşüklüğü ve/veya
median sinir motor distal latans uzaması olanlar orta KTS olarak kabul edildi. Çalışmamızda 86’sı kadın, 35’i
erkek olmak üzere karpal tünel sendromu tanısı alan 189 el değerlendirildi.
Bulgular: Orta KTS’deki latans farkı ve yaş, istatistiksel olarak diğer gruplardan anlamlı derecede yüksekti
(p<0,001). Median-ulnar duyusal sinir 4.parmak latans farkı 0.5 msn ve üzerinde saptanan olguların median
duyusal sinir distal latans değeri 3.0 msn ve üzerindeydi.
Sonuç: Dördüncü parmak median-ulnar duyusal sinir latans farkı testinin, 1.9 msn ve üzerinde olması orta
derecede KTS tanısı koymada yardımcı iken, çok hafif ve hafif KTS derecelendirmesinde bir katkısı yoktur.
Ayrıca bu testin KTS kliniğine sahip, EMG incelemesi normal ve median duysal latans değeri 3.0 msn ve
üzerinde olan olgularda kullanılmasını önermekteyiz.

The value of fourth finger sensory median-ulnar nerve latency difference test in grading Carpal Tunnel Sydrome

Year 2016, Issue: 1, 11 - 15, 01.04.2016

Abstract

Purpose: Fourth finger sensory median-ulnar nerve latency difference test is a frequently used method in
detecting Carpal Tunnel syndromes of especially beginning stage. The objective of this study was to show the
value of fourth finger sensory median-ulnar nerve latency difference test in grading Carpal Tunnel syndrome
and to find out which value second finger sensory median nerve latency should exceed in order to make a
comparative study with fourth finger sensory median-ulnar nerve study.
Materials and methods: If routine nerve conduction studies were normal and the fourth finger sensory medianulnar
nerve latency difference was 0.5 msec and above, CTS was considered to be very mild; if only median
nerve sensory latency extension (over 3.5 msec) was present CTS was considered to be mild; if in addition to
median sensory latency extension there was median sensory amplitude decrease and/or median nerve motor
distal latency extension, CTS was considered to be moderate. 86 women, 35 men, 189 hands with diagnosis of
carpal tunnel syndrome were evaluated in this study.
Results: Latency difference and age in the moderate CTS group was statistically significantly higher when
compared with other groups (p<0.001). The cases whose median-ulnar sensory nerve fourth finger latency
difference was 0.5 msec and the cases above this had median sensory nerve distal latency values of 3.0 msec
and above.
Conclusion: While 1.9 msec and above fourth finger sensory median and ulnar nerve latency difference was
helpful in making a diagnosis of moderate CTS, it did not have a contribution to making very mild and mild CTS
diagnosis. In addition, we recommend this test to be used in cases with CTS clinic, normal EMG examination
and a median sensory latency value of 3.0 msec and over.
