Injections péri-neurales écho-guidées du rameau ventral du 7ème et 8ème nerf spinal cervical chez le cheval sain : étude anatomique post-mortem et évaluation clinique de l’anesthésie tronculaire / Ultrasound-guided peri-neural injections of the 7th and 8th cervical spinal nerve ramus ventralis in normal horses : post-mortem anatomical study and clinical evaluation of the nerve blockTouzot-Jourde, Gwenola 25 January 2018 (has links)
La radiculopathie cervicale caudale a été identifiée comme cause de boiterie affectant le membre antérieur chez le cheval. Les affections dégénératives des articulations intervertébrales des processus articulaires entraînent un remodelage périarticulaire pouvant comprimer les racines du nerf spinal ou leur rameau ventral. Les objectifs de l’étude étaient de décrire la réalisation d’injections échoguidées périneurales du rameau ventral des nerfs spinaux cervicaux 7 et 8 (RV7 et RV8), d’évaluer sur des cadavres de chevaux par dissection la diffusion péri-nerveuse d’une solution colorée ainsi que de décrire chez des chevaux sains les signes cliniques associés à une anesthésie périneurale échoguidée du RV7 et RV8 individuellement. Dans l’étude post-mortem, 5 RV7 et 5 RV8 ont été visualisés échographiquement et colorés par une injection de 7 ou 14 ml de solution colorée. Une portion du tronc nerveux a été trouvée coloré pour chaque injection. La coloration était uniforme transversalement sur toute la largeur du nerf et couvrait une longueur supérieure à 2 cm pour 8 RV alors qu’une coloration de la moitié crâniale du RV sur une longueur de moins de 2 cm pour un RV7 et un RV8. L’étude sur cheval sain portait sur 4 chevaux sains sans image radiographique anormale de la colonne cervicale. Six RV7 et 8 RV8 ont été anesthésiés de la Lidocaïne 2% mélangés à du iohexol. Toutes les injections ont entraîné boiterie antérieure ipsilatérale de l’injection. Les boiteries les plus sévères correspondaient à une parésie du nerf suprascapulaire pour RV7 et à une parésie radiale pour RV8. Cette étude a montré qu’il était possible de réaliser une injection périneurale des RV 7 et RV8 chez le cheval et que l’anesthésie tronculaire des deux racines provoque une atteinte motrice essentiellement de la fonction nerveuse. Ces résultats contribuent à mieux comprendre la symptomatologie des compressions nerveuses cervicales chez le cheval. / Caudal cervical radiculopathy has been identified as a cause of frontlimb lameness in horses. Degenerative conditions of articular process joint result in periarticular remodeling responsible for compression of spinal nerve roots or their ramus ventralis (RV). The objectives of the study were to describe how to perform perineural RV injection under ultrasonographic guidance, to evaluate on cadaver perineural RV staining after a dye solution injection, as well as describe clinical signs associated with a perineural ultranosonography-guided anesthesia of RV7 and RV8 respectively. In the post-mortem study, the RV of the spinal cervical nerves was visualized in all cadavers. Eight RV had a uniform transversal staining of the nerve trunk that covered longitudinally a distance greater than 2 cm. One C7 and one C8 RV showed incomplete transversal staining with a more concentrated color on its half cranial aspect and a longitudinal coverage of less than 2 cm. The in vivo study included 6 RV7 and 8 RV8 perineural injections of a local anesthetic agent, performed on 4 horses that had no abnormal finding on cervical radiographs. All anesthetic injections (lidocaine 2% and iohexol) resulted in modifications of the locomotion with variable degree of lameness on the ipsilateral frontlimb. Severe lameness was characteristic of a suprascapular paresis for RV7 and a radial paresis for RV8. Mild to moderate lameness on the ipsilateral frontlimb included decreased anterior phase of the stride, intern circumduction of the limb and sometimes stumbling for that same frontlimb. Signs of ataxia on the hindlimbs were encountered for 3 injections. This study showed that it is possible to perform perineural injections of RV7 and RV8 in horses and that perineural anesthesia of RV7 and RV8 results in motor dysfunction. These findings constitute a contribution to understanding clinical signs associated with cervical nerve compression in horses.

Treatment Effect of CT-Guided Periradicular Injections in Context of Different Contrast Agent Distribution PatternsReuschel, Vera, Scherlach, Cordula, Pfeifle, Christian, Krause, Matthias, Struck, Manuel Florian, Hoffmann, Karl-Titus, Schob, Stefan 13 June 2023 (has links)
Acutely manifesting radicular pain syndromes associated with degenerations of the lower
spine are frequent ailments with a high rate of recurrence. Part of the conservative management are
periradicular infiltrations of analgesics and steroids. The purpose of this study is to evaluate the
dependence of the clinical efficacy of CT-guided periradicular injections on the pattern of contrast
distribution and to identify the best distribution pattern that is associated with the most effective pain
relief. Using a prospective study design, 161 patients were included in this study, ensuring ethical
standards. Statistical analysis was performed, with the level of statistical significance set at p = 0.05.
A total of 37.9% of patients experienced significant but not long-lasting (four weeks on average)
complete pain relief. A total of 44.1% of patients experienced prolonged, subjectively satisfying pain
relief of more than four weeks to three months. A total of 18% of patients had complete and sustained
relief for more than six months. A significant correlation exists between circumferential, large area
contrast distribution including the zone of action between the disc and affected nerve root contrast
distribution pattern with excellent pain relief. Our results support the value of CT-guided contrast
injection for achieving a good efficacy, and, if necessary, indicative repositioning of the needle to
ensure a circumferential distribution pattern of corticosteroids for the sufficient treatment of radicular
pain in degenerative spine disease.
