To our knowledge, this is the first study to investigate this relationship by anatomically comparing C5-C6 nerve root translation before and after root untethering by cutting the cervical foraminal ligaments (FL). <b>Objective</b>  The aim of this study is to determine if C5 root untethering through FL cutting results in increased root translation. <b>Methods</b>  Six cadaveric dissections were performed. Nerve roots were exposed via C4-C6 corpectomies and supraclavicular brachial plexus exposure. Pins were inserted into the C5-C6 roots and adjacent foraminal tubercle. Translation was measured as the distance between pins after the SC was dorsally displaced 5 mm before and after FL cutting. Clinical feasibility of FL release was examined by comparing root translation between standard and extended (complete foraminal decompression) foraminotomies. Translation of root levels before and after FL cutting was compared by two-way repeated measures analysis of variance. Statistical significance was set at 0.05. <b>Results</b>  Significantly more nerve root translation was observed if the FL was cut versus not-cut, <i>p</i>  = 0.001; no difference was seen between levels, <i>p</i>  = 0.33. Performing an extended cervical foraminotomy was technically feasible allowing complete FL release and root untethering, whereas a standard foraminotomy did not. <b>Conclusion</b>  FL tether upper cervical nerve roots in their foramina; cutting these ligaments untethers the root and increases translation suggesting they could be harmful in the context of C5P. Further investigation is required examining the value of root untethering in the context of C5P.</p>","PeriodicalId":15280,"journal":{"name":"Journal of Brachial Plexus and Peripheral Nerve Injury","volume":"15 1","pages":"e9-e15"},"PeriodicalIF":0.7,"publicationDate":"2020-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-0040-1712982","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38215485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An anomalous innervation arising from the accessory deep peroneal nerve is described in 15% of cases.1 An “all tibial foot” innervation pattern has been reported.2,3 In our clinic, electromyographic findings revealed the presence of a deep peroneal to posterior tibial nerve anastomosis similar to the forearm anastomosis of the median to ulnar nerve of Martin and Gruber. In ►Fig. 1, tracings of the EDB compound muscle action potential (CMAP) were generated after stimulation at various sites in the foreleg (►Fig. 2). The medially located tarsal tunnel is a site that will not generate an EDB CMAP unless there is an anomalous innervation to the EDB. In our cases, the distal peroneal site of stimulation failed to generate a maximal CMAP. Additional amplitude occurred after stimulation of the distal tibial nerve in the tarsal tunnel. Proximal peroneal and distal tibial nerve stimulations are characteristics of a cross over in the foreleg from the peroneal to the tibial nerve (►Fig. 3). Of 72 patients, 11% (8/72) showed these results. It was present in both legs in half of the patients (4/8). The finding of a deep peroneal to posterior tibial anastomosis will be of interest to neurologists performing electromyographic studies and surgeons that deal with injuries to the foreleg.

Normally the amplitude of the CMAP of the EDB obtained by stimulation of the deep peroneal nerve at the ankle would be equal to that obtained by stimulation at the popliteal fossa, that is, trace A would equal with B. With a deep peroneal to posterior tibial anastomosis, a response is elicited by stimulating the posttibial nerve at the medial ankle (trace D).
