Operative Findings in Reoperation of Patients with Cubital Tunnel Syndrome

The purpose of this study was to report the operative findings in patients who underwent a secondary operation for cubital tunnel syndrome. A chart review was performed of 100 patients who had undergone a secondary operation for cubital tunnel syndrome by one surgeon. The mean age was 48 years (standard deviation 13.5 years). The most common complaint after primary surgery was increased symptoms in the ulnar nerve distribution (n = 55) and pain in the medial antebrachial cutaneous nerve distribution (n = 55). The most common operative findings included a medial antebrachial cutaneous nerve neuroma (n = 73) and a distal kink of the ulnar nerve (n = 57). This kink was noted as the nerve moved from its transposed position anterior to the medical epicondyle to its native position within the flexor carpi ulnaris. This study suggests that during primary surgery for cubital tunnel syndrome care should be given to avoid injury to the medial antebrachial cutaneous nerve, distal kinking of the ulnar nerve with transposition and pressure on the transposed nerve by the fascial flaps or tendinous bands.     

肘管综合征的手术治疗

目的：探讨尺神经松解前移手术治疗肘管综合征的临床效果。方法：工治疗肝管综合征26例，观察尺侧上副供血情况。结果：经随访，本组病例尺神经功能有较大改善。结论：尺神经松解前移术为治疗肘管综合征的较佳术式。     

肘管综合征29例分析

报告1982年至1995年手术治疗肘管综合征29例,均行尺神经松解前置术,部分还进行了神经内松解。优良率达92％。作者认为在分析尺神经卡压因素时,要重视由于肘管弓状韧带解剖变异所致的卡压因素。另外,肌电检查或分段肌电检查很有必要,不只是对肘管综合征的诊断与鉴别诊断有意义,而且对手术方式的选择决定是否神经内松解亦有特殊的意义。在手术显微镜下进行无损伤操作是提高疗效的重要手段。     

肘管综合征的成因和神经学检查

肘管综合征是常见的周围神经嵌压症之一。我院1990年12月—1995年12月共收治该症22例,均经严格的神经学检查和病因学分析后确诊,治疗全部行尺神经前移术。术后随访20例,平均随访2年5月,12例恢复正常,6例明显好转,2例较差。作者认为,当手部感觉改变和运动障碍为单纯尺神经损伤引起,肌电图提示尺神经传导速度在肘管部减慢,肘管内或外可找到神经受损原因,肘管综合征即可确诊;当肌电提示尺神经传导在肘管部减慢,而肘管内或外找不到神经受损原因,应高度疑诊肘管综合征。     

带筋膜尺神经前移治疗肘管综合征

目的 研究带筋膜尺神经前移在肘管综合征治疗中的应用。方法 采用带筋膜的尺神经多术治疗４０例肘管综合征。结果 感觉运动评分提高了３９．２％,有效率达９１．８％。结论带筋膜尺神经前移治疗肘管综合征有助于保护尺神经的血供及神经分支。慢性肘部牵拉伤是导致肘管综合征的主要因素。     

Ultrasound‐Assisted Precise In Situ Decompression for Cubital Tunnel Syndrome

ObjectiveTo explore the effect of locating the ulnar nerve compression sites and guiding the small incision so as to decompress the ulnar nerve in situ on the elbow by high‐frequency ultrasound before operation.MethodsA retrospective analysis was conducted on 56 patients who underwent ultrasound‐assisted in situ decompression for cubital tunnel syndrome from May 2018 to August 2019. The patients'' average age was 51.13 ± 7.35 years, mean duration of symptoms was 6.51 ± 1.96 months, and mean postoperative follow‐up was 6.07 ± 0.82 months. Nine patients had Dellon''s stage mild, 39 had stage moderate, and eight had stage severe. Ultrasound and electromyography were completed in all patients before operation. The presence of ulnar nerve compressive lesion, the specific location, and the reason and extent of compression were determined by ultrasound. A small incision in situ surgery was given to decompress the ulnar nerve according to the pre‐defined compressive sites.ResultsAll patients underwent in situ decompression. The compression sites around the elbow were as follows: two in the arcade of Struthers, one in the medial intermuscular septum, four in the anconeus epitrochlearis muscle, five beside the cyst of the proximal flexor carpi ulnaris (FCU), and the remaining 44 cases were all from the compression between Osborne''s ligament to the two heads of the FCU. The compression localizations diagnosed by ultrasound were confirmed by operations. Preoperative ultrasound confirmed no ulnar nerve subluxation in all cases. The postoperative outcomes were satisfactory. There was no recurrence or aggravation of symptoms in this group of patients according to the modified Bishop scoring system; results showed that 43 cases were excellent, 10 were good, and three were fair.ConclusionsHigh‐frequency ultrasound can accurately and comprehensively evaluate the ulnar nerve compression and the surrounding tissues, thus providing significant guidance for the precise minimally invasive treatment of ulnar nerve compression.
