Thirty-two elbows in 31 patients diagnosed as having cubital tunnel syndrome underwent ultrasonographic examination to assess morphological changes in the ulnar nerve and its surrounding tissues. On longitudinal images, the site of constriction due to the fibrous band and proximal swelling of the nerve were observed by ultrasonography and were confirmed intraoperatively. On axial images, the lengths of the major axis [7.2 (SD 1.6) mm] and the minor axis [3.7 (0.9) mm] of the nerve at the medial epicondyle were greater than those in normal subjects. There was a correlation between the stage of ulnar nerve palsy and the diameter of the major axis. Preoperatively, ganglia were detected by ultrasonography in the cubital tunnel in three cases and an anconeus epitrochlearis muscle in two.
对31例诊断为肘管综合征的患者的32个肘部进行了超声检查，以评估尺神经及其周围组织的形态学变化。在纵向图像上，通过超声检查观察到纤维带导致的狭窄部位和神经近端肿胀，并在术中得到证实。在轴位图像上，内侧髁上神经的长轴[7.2（标准差1.6）mm]和短轴[3.7（0.9）mm]长度大于正常受试者。尺神经麻痹的分期与长轴直径之间存在相关性。术前，超声检查在3例患者的肘管内检测到神经节，2例检测到肱三头肌内侧头。
