Abstract:
The aim of our study was retro and prospective analysis of ultrasonographic parameters in the diagnosis of carpal tunnel
syndrome. Preoperative median nerve was examined by ultrasonography being taken the following parameters - the length
in the transverse plane (T) and thickness in the sagittal plane at the level of proximal entrances (D) of the median nerve in
the carpal tunnel, the smallest thickness in the sagittal plane at channel or at the distal outlet (d). Were used the following
indices: cross-sectional area of the median nerve (AT norm to 7 mm2
), AT = 3.14xTxD/4, the ratio of R = T/D (norm up to
3.3), and IGP degree of compression index = 100 (1-d/D) (rule around 10%).
In the Hand Surgery Department of IMSP CHTO in period 2011-2015 we present data of 202 patients with carpal tunnel
syndrome. Report male - female is 2.74: 1.
Mean age 55.6 ± 11.9. In 91 (45.05%) was determined PCTs. At 111 (54.95%) patients with CTS in association with traumatic
factor the mean (md) mdAT = 15,06mm2
, mdTD = 2.12; mdIGP 52.00%. In TCTS mdAT = 13,81mm2
; mdTD = 2.06;
mdIGP = 52.43%.
Following surgery, with amelioration of disease at 6 weeks in the group with CTS were examined by ultrasound to determine
mdAT = 14,43mm2, mdTD = 2.12; mdIGP = 21.78%; the SCCT lot mdAT = 16,96mm2; mdTD = 2.17; mdIGP = 22.82%.
At 3 months at 50 patients, of which 23 with CTS was determined mdAT = 13,52mm2, mdTD = 2.01; mdIGP = 13.13%; in
group TCTS with 27 patients – mdAT = 14,96mm2; mdTD, 2.10; mdIGP, 10.82%.
Conclusion
· Problem diagnosis and treatment of these patients until now remains current, despite of successes in the treatment of
orthopedic and experience in the treatment of CTS
· In our study, the absolute majority of patients by ultrasound investigation has been determined that IGP is more
demonstrative than AT and TD.
· Because the compression is the primary factor in the pathogenesis of CTS, the appreciation of PGI allows the determination
of treatment strategy.
