Anatomical changes of the median nerve in patients with carpal tunnel syndrome
摘要
Abstract
Objective To observe the anatomical changes of the median nerve ( MN) in patients with carpal tunnel syndrome(CTS).Methods 15 patients with CTS (observation group), including 10 mild cases, 12 moderate cases and 8 severe cases, and 15 healthy persons (control group) were selected.Color Doppler ultrasonography was performed on two groups.The cross section areas(CSAs)of MN at three cross sections of articulatio radioulnaris , pisiform bone and hook of hamate bone were calculated .Results The thickness of ligament carpi transversum at cross section of pisiform bone and hook of hamate bone , the MN flattening ratio ( MNFR) in patients with different state of illness were calculated .In observa-tion group and control group, CSAs of MN were (0.10 ±0.02)and(0.06 ±0.01)cm2, (0.15 ±0.03)and(0.08 ±0.02) cm2, (0.12 ±0.02) and(0.06 ±0.02)cm2 at cross sections of articulatio radioulnaris, pisiform bone, hook of hamate bone respectively, compared the two groups , P<0.01.In mild cases, moderate cases and severe cases , the thickness of ligament carpi transversum at cross section of hook of hamate bone was (0.40 ±0.02), (0.43 ±0.03), (0.46 ±0.03)cm respectively, the MNFR was 3.32%±0.43%, 3.47%±0.23%, 3.69%±0.12% respectively, compared the mild, moderate and severe cases , P<0.05.In mild cases, moderate cases and severe cases , the thickness of ligament carpi transversum at cross section of pisiform bone was (0.30 ±0.02), (0.36 ±0.06), (0.40 ±0.03)cm respectively.the MNFR was 2.87%±0.34%, 3.12%±0.43%, 3.33%±0.11%respectively,compared the mild, moderate and severe cases, P<0.05.Conclusions The anatomical changes of the MN in patients with CTS are CSAs obviously increasing at three cross sections of articulatio radioulnaris , pisiform bone and hook of hamate bone .With the aggravation of state of ill-ness, the thickness of ligament carpi transversum at cross section of pisiform bone and hook of hamate bone , and the MNFR are obviously increasing .关键词
