目的 从解剖及临床方面报告内窥境下腕管松解术的解剖人路及手术方法，旨在提高手术疗效、减少手术并发症。方法 以１８侧新鲜成人上肢标本及２６侧福尔马林液固定的成人上肢标本为对象，观察在内窥镜下碗管松解术入路的解剖结构，观察、测量及定周围相关组织结构。临床应用１９例２１侧，镜视下切断腕横韧带，手术在局麻、无止血带下进行。结果观测屈肌支持带、正中神经圾其分支和掌浅弓等结构。手术入口为腕横纹近端２～３ｃｍ、

Carpal tunnel release using universal subcutaneous endoscope system: anatomical study and clinical application

Objective To report carpal tunnel release using Universal Subcutaneous Endoscope System from anatomical and clinical point of view for the purpose of avoiding operative complication and improving clinical efficacy. Methods Operation approach and adjacent structures were observed and measured on 18 fresh upper limb specimens and 26 formaldehyde solution fixed upper limb specimens. Nineteen patients with 21 carpal tunnel syndrome (CTS) were treated with this method under local anaesthesia without tourniquet. The incision is made in the wrist just 2-3 cm superior to palmar crease of the wrist at the medial border of the palmaris longus. The operation plane is just under the deeper layer of deep fascia. The instrument points to the third web. The median nerve and its branches, flexor retinaculum and superficial palmar arch were carefully observed. Results The results were satisfactory in all patients. Conclusion Single wrist portal arthroscopic procedure is a safe, simple and efficient approach if the anatomic structures of the wrist are perfectly clear to the opeator.
