Dorsal suspension for Morton’s neuroma: A comparison with neurectomy

BackgroundThe purpose of this study was to investigate and compare the clinical outcomes of dorsal suspension with those of neurectomy for the treatment of Morton’s neuroma.MethodsWe conducted a retrospective study of dorsal suspension and neurectomy group. The dorsal suspension was performed by dorsal transposition of neuroma over the dorsal transverse ligament after neurolysis. The visual analog scale (VAS), the Foot and Ankle Ability Measure (FAAM), postoperative satisfaction, and complications were evaluated.ResultsBoth groups reported significant pain relief, and there were no significant differences between the groups with respect to postoperative pain. The postoperative FAAM outcomes showed no significant between-group differences. Satisfaction analysis showed ‘excellent’ and ‘good’ results in the dorsal suspension and neurectomy groups (95% and 77.7%, respectively). Complications of numbness and paresthesia reported in the dorsal suspension group (5% and 5%, respectively) were significantly fewer than those of neurectomy group (61.1% and 33.3%, respectively) (both, p < .05).ConclusionsWith its favorable results, dorsal suspension can be another operative option for the treatment of Morton’s neuroma.Level of Evidence: Level III, retrospective comparative case series.     

Earthquake generated proximal tibial nerve compression treated by surgery

Purpose

This article reports on nine cases of proximal tibial nerve compression by the soleal tendinous arch caused by unsuitable treatment of acute compartment syndrome (ACS). Also, we report the clinical results of neurolysis and analyse the cause of this special type of neurological compression.

Methods

There were nine extremities in nine patients included in the study. All patients were among the victims of the Wenchuan earthquake in 2008. All patients had a previous lower extremity ACS. Pain level, numbness in the sole, muscle strength of the flexor hallucis longus and Tinel’s sign were evaluated pre- and post-operatively. Each proximal tibial nerve compression was subjected to neurolysis with division of the soleal tendinous arch.

Results

At a mean follow-up of 22 months, eight patients (87 %) with weakness of the flexor hallucis longus showed improvement in flexor strength and seven patients (78 %) exhibited improved sensory function in the sole. All patients experienced pain relief. Subjective pain was reduced from an average score of 2.7 to 0.7 based on a visual analogue scale. Physical examination for Tinel’s sign revealed all patients experienced relief of radiating pain, but two patients still retained a positive Tinel’s sign (mild) over the soleal tendinous arch. In summary, four patients were highly satisfied, four were satisfied and one was neither satisfied nor dissatisfied with functional recovery after neurolysis.

Conclusions

Unsuitable treatment of lower extremity ACS can lead to tibial nerve compression beneath the soleal tendinous arch. Neurolysis may improve pain and sensory and motor function.     

Neurólisis del plexo celiaco intraoperatoria directa frente a percutánea guiada por tomografía computarizada en el cáncer de páncreas no operable: estudio aleatorizado,controlado y de no inferioridad

BackgroundCeliac plexus neurolysis (CPN) has been used to control pancreatic cancer (PC) pain, up to our knowledge, there is no study compared intraoperative CPN and computed tomography (CT)-guided techniques.ObjectivesTo compare the effects of intraoperative and CT-guided CPN in unresectable PC on pain intensity and analgesic requirements.MethodsA total of 90 patients were enrolled in this prospective, randomized, open label, controlled, non-inferiority study, 20 patients were excluded or lost to follow up. The patients were randomly allocated to either intraoperative or CT-guided CPN group. A mixture of 20 ml ethanol 90%, 100 mg lignocaine and 5 mg dexamethasone was infused on each side of the aorta in both groups. Visual analogue score (VAS) and oral daily tramadol consumption were recorded at day 7, 14, 30, 60, 120 and 180 days after intervention. Occurrence of any intervention related complications were reported.ResultsMedian VAS was similar in both intraoperative and CT-guided CPN groups from day 7 up to 180 days after intervention. The median daily analgesic consumption of oral tramadol (mg) was comparable in both intraoperative and CT-guided CPN groups after intervention at day 7 (50 versus 50), day14 (50 versus 50), day 30 (50 versus 50), day 60 (50 versus 50), day 120 (100 versus 75) and day 180 (100 versus 100). The incidence of diarrhea, vomiting, hypotension and back pain was similar in both groups.ConclusionIntraoperative CPN is non-inferior to CT-guided CPN as both techniques were similarly associated with reduced pain severity and analgesics requirements.

尺神经前置术中可吸收膜对电生理的早期疗效

目的观察尺神经前置术中聚乳酸可吸收医用膜对神经电生理恢复的早期效果。方法收集肘管综合征患者共34人:10人为肘部外伤后引起尺神经卡压,24人无明显诱因;均予肘部尺神经松解、皮下前置术。术中尺神经表面包裹可吸收医用膜者19侧,未使用者17侧。随访时间2～15个月。随访肌电图:肘上5cm～肘下5cm神经传导速度、以及在肘部刺激尺神经后于小鱼际肌引出CMAP波幅的术前术后的区别。结果2组在肘部尺神经卡压段的传导速度(MNCV)均有明显改善,其中,对照组1人,观察组3人术前小指展肌无法引出CMAP,MNCV为0,术后有不同程度的恢复。余下患者中,对照组MNCV差值平均改善程度有43.0%,观察组平均改善程度有58.7%,但总体上2组统计学意义上无明显差别。波幅方面,对照组在小指展肌引出的CMAP波幅较术前平均改善程度54.6%,观察组108.3%。且总体上两组波幅改变程度有统计学意义上差别。结论聚乳酸可吸收医用膜在肘部尺神经松解、前置术中对神经电生理早期恢复有一定效果。     

A 32-year experience with the surgical treatment of selected brachial plexus lesions with emphasis on its reconstruction

Twenty-five patients with brachial plexus injury were treated by anastomosis, neurolysis, and calvicular decompression. The patients treated by anastomosis are described in detail because evidence of regrowth of axons across the anastomosis can be documented, whereas the effects of neurolysis are difficult to judge. The techniques of brachial plexus reconstruction are illustrated. Clinical improvement occurred in 93% of patients treated with anastomosis, 89% of those treated with neurolysis, and 100% of those treated with decompression. Electromyographic studies provided valuable information in assessment before and after surgery. The benefits of surgical therapy of brachial plexus injuries outweigh the risks in carefully selected patients.

目的报道肘管综合征的显微外科治疗效果。方法显微镜下神经外膜或内膜松解，将尺神经前置并埋于前臂屈肌群内，神经入出口处保持一定宽松度，术后用石膏托将肘关节固定于45°屈肘位。结果随访时间为6～24个月，手术部位皮下未扪及神经，叩击无放电感，明显肌肉萎缩者症状无加重，爪形手畸形有所恢复；轻度肌肉萎缩者肌力明显改善，无肌肉萎缩者手部活动灵活度功能恢复，尺侧半手指皮肤感觉异常消失。结论显微外科神经松解并将其前置埋于肌膜下是治疗肘管综合征的有效方法。     

Neurólisis robótica del pudendo en el tratamiento del síndrome de atrapamiento del pudendo

Introduction

Pudendal nerve entrapment syndrome (PNE) is characterised by the presence of neuropathic pain in the pudendal nerve (PN) territory, associated or not with urinary, defecatory and sexual disorders. Surgical PN decompression is an effective and safe alternative for cases when conservative treatment fails. The aim of this study is to describe the first robot-assisted pudendal neurolysis procedure performed in our country.
