“…Diagnosis is achieved through the use of MRI, which is the preferred imaging modality [8,9]. T1-weighted spinecho or fast spin-echo sequences can characterize the nerve's anatomy along with its surrounding structures, while T2-weighted spin-echo or fast spin-echo sequences allow for better identification of edema within the nerve and its surrounding structures [8,9].…”

SUMMARY:The objective of this study was to evaluate morphological changes of the median nerve in patients with carpal tunnel syndrome (CTS) and healthy controls, to correlate the MRI findings of wrists. This study compared not only morphological changes of the median nerve and also displayed descriptively structures in carpal tunnel between patients diagnosed with idopathic CTS and healthy controls. Our study involved 60 hand, 30 of hand were evaluated diagnosed with idiopathic CTS and 30 hand as healthy controls bilaterally. Two provocative tests (Phalen's and Tinel's test) were performed on each hand for both the patient group (60 wrist) and the control group (60 wrist). With regard to Phalen and Tinel's test results, 24 and 26 wrists were excluded from patient and control groups respectively. Totally 70 wrists were evaluated, and in terms of cross-sectional area of median nerve at the level of distal radioulnar joint, pisiform bone and the hook of hamate bone by MRI in the patient and control groups. In addition to evaluation of crosssectional area of median nerve, we determined signal intensity of wrists and different localization of the median nerve in the carpal tunnel. Cross-sectional area of the median nerve measured by wrist magnetic resonance at the level of metacarpal bones and signal intensity of wrists may be considered as a valuable indicator to determine patients referred with idiopathic CTS.

“…Pathophysiologisch gibt es viele Ursachen, die zu einer kompressiven Neuropathie führen können [5,7]. Wie bereits erwähnt, kann ein peripherer Nerv in einem kongenital eng angelegten fibrösen oder fibroossären Tunnel komprimiert werden.…”

. 2). Ebenfalls innerhalb des Tarsaltunnels (Lokalisation 0-2 cm proximal einer imaginären Linie von der Malleolarspitze zum Tuber calcanei) teilt sich der N. tibialis in seine 2 Endäste auf, den N. plantaris medialis und den N. plantaris lateralis. Bereits beim Eintritt des N. tibialis in den Tarsaltunnel gehen die dorsalsten Endäste des N. tibialis (Rr. calcanei mediales) ab und ziehen unter dem Retinakulum nach dorsokaudal, um sensibel die Haut des medialen Anteils der Ferse und den anschließenden Anteil der Fußsohle zu versorgen. Als Variante können die Rr. calcanei mediales auch das Retinakulum selbst durchbohren oder zwischen dem Retinakulum und der Faszie des M. abductor hallucis austreten.Da die Kompression entweder den ganzen Stamm des N. tibialis oder aber weiter distal isoliert nur einen der beiden Nn. plantares betreffen kann, unterscheidet man ein proximales und ein distales Tarsaltunnelsyndrom. Das distale betrifft den medialen oder lateralen plantaren Nerv in ihrem Verlauf unter dem M. abductor hallucis.
