肘部尺神经卡压与尺神经半脱位的诊疗进展

肘部尺神经卡压也称为肘管综合征,可造成手部一系列功能障碍,是最常见的上肢神经卡压症之一。尺神经脱位及半脱位为尺神经卡压的影响因素。尺神经卡压按McGowan分级分为Ⅰ、Ⅱ、Ⅲ级。Ⅰ级首选保守治疗 Ⅱ、Ⅲ级保守治疗效果欠佳,多需要手术治疗。手术方式主要有尺神经原位松解术（包括肱骨内髁切除术）、粘膜下尺神经前置术、肌下尺神经前置术及肌内尺神经前置术等,其中原位松解手术操作相对简单,但对于尺神经卡压伴有尺神经脱位者多属禁忌,应首选尺神经前置术。

Advancement on Diagnosis and Treatment of Ulnar Nerve Compression and Subluxation

Ulnar nerve compression of elbow called as cubital tunnel syndrome is one of most common nerve compression of upper extremity injury and can cause a series dysfunctions of hand. Subluxation or luxation of ulnar nerve is the influential factor of ulnar nerve compression. Ulnar nerve compression is classified as grade Ⅰ ,Ⅱ and Ⅲ according to McGowan system. Expectant treatment is the first choice for patients of grade Ⅰ . Surgical intervention is usually applied in grade Ⅱ and Ⅲ patients due to non-ideal effect of expectant treat- ment. The procedures include ulnar nerve relaxation in situ, subcutaneous anterior transposition, submuscular anterior transposition and intramuscular anterior transposition. The procedure of ulnar nerve relaxation is sim- ple, but not suitable for ulnar nerve compression accompanied with luxation. However, anterior transposition is the preferred procedure for such kind of patients.
