《Clinical neurophysiology》2019,130(2):297-302
ObjectiveTo assess the diagnostic performance of electrophysiology and nerve ultrasound in ulnar neuropathies of varying clinical severity in 135 consecutive patients.MethodsClinical severity of ulnar neuropathy was graded on a 4 point scale from very mild (symptoms only) to severe (marked atrophy of intrinsic hand muscles). Sensitivity and localization ability of electrophysiology and nerve ultrasound were assessed for each point of the scale.ResultsUltrasound had higher sensitivity than electrophysiology in clinically very mild (20% and 3% for ultrasound and electrophysiology, respectively) and mild (62% and 47% for ultrasound and electrophysiology, respectively) neuropathies, had greater localizing ability in axonal ulnar neuropathies, and identified nerve hypermobility.Ultrasound nerve cross-sectional area had strong positive correlation with both clinical and electrophysiological severity scores, but with significant overlap across the severity groups.ConclusionThe diagnostic work-up of ulnar neuropathies was improved by using both electrophysiology and ultrasound at all levels of clinical severity. Ultrasound increased the diagnostic yield in very mild and mild neuropathies, localized all the ulnar neuropathies with abnormal non-localizing electrophysiology and identified nerve hypermobility.SignificanceThis is the first detailed analysis of the diagnostic performance of electrophysiology and ultrasound in ulnar neuropathies of varying severity. 相似文献

We examined radiographs of the elbows of the pitching arms of 79 professional baseball pitchers (mean age, 25.1 years; mean
duration of professional career, 4.7 years) and noted the frequency and size of spurs, bone fragments, and intra-articular
loose bodies according to site. The influence of duration of professional baseball career on these osteoarthritic changes
was also investigated. The olecranon tip was the most frequent site of spurs (62/79; 78.5%), and fragmentation of the spur
was detected in 17 joints. The frequency of spurs was also high at the medial margin of the olecranon, the tip of the coronoid
process, the medial margin of the sigmoid notch, the medial margin of the trochlea and the olecranon fossa. In 38 subjects,
spurs were observed at the distal portion of the radial notch of the ulna. However, few pitchers had osteoarthritic changes
in the humeral capitellum or radial head. Intra-articular loose bodies were detected in 4 of 79 joints (5.1%), and bone fragments
were present below the medial humeral epicondyle in 25 of 79 joints (31.6%). Osteoarthritic changes in the elbow joint appeared
to be attributable mainly to traction stress and impingement associated with extension and valgus strain. Significant osteoarthritic
changes were often found in professional pitchers whose careers exceeded 5 years. 相似文献

肘关节后脱位并尺骨冠状突骨折9例临床疗效分析 总被引:6,自引:0,他引:6
目的 探讨肘关节后脱位并尺骨冠状突骨折的治疗方法。方法 总结2000年3月~2003年5月9例肘关节后脱位合并尺骨冠状突骨折患者的治疗经验,根据骨折类型分别采用内外侧入路对8例患者进行手术治疗,术后配合早期功能锻炼。结果 所有患者随访8~24个月,根据HSS评分标准,优5例(55.6%),良2例(22.2%),一般2例(22.2%),优良率77.8%,无严重肘关节并发症发生。结论 选择恰当的手术入路和早期功能锻炼是提高该类骨折效果的关键。 相似文献
