Abstract

Objective: Many clinicians are unfamiliar with a diagnosis of lacertus syndrome (LS). We investigated the value of the lacertus notch sign in diagnosing LS.

Methods: We included 56 consecutive patients (112 upper extremities) who had neuropathic pain and neurological symptoms of the hand. The presence of LS and the lacertus notch sign in each upper extremity was assessed.

Results: Of the 83 upper extremities with LS, 54 (65.1%) had a lacertus notch sign, whereas 29 (34.9%) did not. Of the 29 upper extremities without LS, 9 (31.0%) and 20 (69.0%) had and did not have a lacertus notch sign, respectively. The rates of lacertus notch presence in upper extremities with and without LS were significantly different. Of the 63 upper extremities with a lacertus notch sign, 54 (85.7%) were diagnosed with LS, whereas 9 (14.3%) were not. Of the 49 upper extremities without a lacertus notch sign, 20 (40.8%) were diagnosed with LS, and 29 (59.2%) were not. We observed significant differences in the rates of LS in upper extremities with and without lacertus notch.

Conclusions: The presence of the lacertus notch sign is useful for diagnosing LS. When patients with neuropathic pain and neurological symptoms present with a lacertus notch sign, clinicians should consider the possibility of LS.

作为拉克特综合征标志的拉克特凹痕。

目的：许多临床医生对腔隙综合征（LS）的诊断并不熟悉。我们研究了拉克图斯切迹征在诊断拉克图斯综合征中的价值：我们连续收治了 56 名手部有神经病理性疼痛和神经症状的患者（112 名上肢患者）。方法：我们连续纳入了 56 例（112 只上肢）手部神经痛和神经症状患者，评估了每只上肢是否存在 LS 和裂隙征：结果：在 83 个有 LS 的上肢中，54 个（65.1%）有拉克尔特切迹，29 个（34.9%）没有。在 29 例未出现 LS 的上肢中，分别有 9 例（31.0%）和 20 例（69.0%）出现和未出现裂隙切迹。有LS和没有LS的上肢中，出现裂隙切迹的比例有显著差异。在63例有裂隙切迹的上肢中，54例（85.7%）被诊断为LS，9例（14.3%）未被诊断为LS。在 49 例无腔隙切迹的上肢中，20 例（40.8%）被诊断为 LS，29 例（59.2%）未被诊断为 LS。我们观察到，在有和无腔隙切迹的上肢中，LS的发病率存在明显差异：结论：腔隙切迹的存在有助于诊断 LS。当神经病理性疼痛和神经症状患者出现裂隙切迹时，临床医生应考虑 LS 的可能性。

期刊介绍： Pain Practice, the official journal of the World Institute of Pain, publishes international multidisciplinary articles on pain and analgesia that provide its readership with up-to-date research, evaluation methods, and techniques for pain management. Special sections including the Consultant’s Corner, Images in Pain Practice, Case Studies from Mayo, Tutorials, and the Evidence-Based Medicine combine to give pain researchers, pain clinicians and pain fellows in training a systematic approach to continuing education in pain medicine. Prior to publication, all articles and reviews undergo peer review by at least two experts in the field.
