Epidural Injections

Objectives: Trans-foraminal epidural injections have been used successfully to aid in the management of cervicobrachialagia. The aim of this study was to assess the cross sectional area of the vertebral artery during transforaminal cervical nerve root injections (TFCNRI) when the head is typically rotated and to compare with the neutral position cross sectional area. We hypothesize that head rotation does not lead to a change of vertebral artery calibre at the neural foramen, thus this technique can be performed relatively safely during TFCNRI. Material and Methods: A pilot study involving a retrospective review of 16 computed tomography guided TFNRI was performed and cross sectional area of vertebral artery with head tilted and head in neutral position was performed. Results: There was no correlation between the degree of head rotation and change in the area of the ipsilateral or contralateral vertebral artery. Conclusion: We suggest that head can safely be rotated to varied degrees while performing TFCNRI.

Objective To assess the relevance of electrodiagnosis (EDX) in the cross-sectional area (CSA) of the nerve root of patients with cervical radiculopathy (CR) by using high-resolution ultrasonography (HRUS).Methods The CSAs of the cervical nerve roots at C5, C6, and C7 were measured bilaterally using HRUS in 29 patients with unilateral CR whose clinical symptoms, magnetic resonance imaging (MRI) findings, and EDXresults corresponded with each other (CR-A group), and in 26 patients with unilateral CR whose clinical symptoms and MRI findings matched with each other but did not correspond with the EDX findings (CR-B group). Results The CSA of the affected side in each nerve root was significantly larger than that of the unaffected side in both the CR-A and CR-B groups. The side-to-side difference in the bilateral CSAs of the nerve root and the ratio of the CSAs between the unaffected and affected sides were statistically larger in the CR-A group than in the CR-B group.Conclusion The increased CSAs in the CR-A group reflect the physiological changes of the cervical nerve root, which is supported by the EDX findings.

The purpose of this study was to determine the differences in the muscle cross-sectional area (MCSA) of the triceps surae in the supine and sitting positions using magnetic resonance imaging (MRI), and the relationship between the MCSA of the triceps surae in the sitting position and muscle thickness (MT), assessed using MRI and ultrasonography, respectively. This study included 16 healthy young male participants. The measurement positions were 90° flexion of the knee joint and neutral position of the ankle joint in the sitting or supine positions. Using an open-configuration MRI system with a vertical gap and ultrasonography, we measured the MCSA and MT of the soleus muscle and the medial and lateral heads of the gastrocnemius muscle at three selected locations in the ventral part of the muscle. As a result, the 50% portion of the soleus muscle and the 25% and 50% portions of the gastrocnemius medial and lateral heads were higher in the sitting position than in the supine position. Furthermore, only 50% of the gastrocnemius medial head showed a correlation between the MCSA and MT. When using the MT of the triceps surae as an indicator of muscle volume in the sitting position, the muscle site should be considered.

Abstract OBJECTIVE AND IMPORTANCE: Extradural hemangioblastomas account for 8 to 12% of all spinal hemangioblastomas. Among them, intra-extradural forms with a dumbbell extension are extremely rare. We report a case of intra-extradural hemangioblastoma involving the C6 cervical nerve root. CLINICAL PRESENTATION: The patient was a 31-year-old woman presenting with signs of myelopathy and C6 radiculopathy on the right side. A computed tomographic scan and magnetic resonance imaging demonstrated a dumbbell tumor that had developed through the C5–C6 intervertebral foramen. Angiography revealed a well-circumscribed mass with feeders from the vertebral artery and the deep cervical artery. INTERVENTION: The tumor was totally removed through the lateral approach, with control of the vertebral artery and sacrifice of the C6 cervical nerve root. Limited bone drilling to enlarge the foramen permitted us to reach and resect the intradural component. Histopathological examination confirmed the diagnosis of hemangioblastoma. Follow-up was uneventful. CONCLUSION: This is the sixth reported case of a cervical dumbbell hemangioblastoma investigated by computed tomographic scanning and MRI but the first one resected via the lateral approach. The lateral approach seems appropriate for surgical resection because it provides primary control of the vascular feeders and access to the extradural and intradural components.

Root Injury

Penetrating vertebral artery injury is uncommon yet potentially fatal. We present two cases of penetrating vertebral artery injury with concomitant cervical nerve root injury managed in our centre. The first case was a young gentleman who suffered from neck injury by broken metal fragment. Cervical nerve root injury was suspected preoperatively. Massive bleeding from vertebral artery was encountered during wound exploration. It was managed by ligation, followed by retrograde endovascular embolisation. The second case was a young lady being assaulted with knife and fork over the neck. She was also suspected to have cervical nerve root injury preoperatively. Vascular control of vertebral artery was achieved with endovascular intervention. Subsequent operation for foreign body removal and nerve root repair was performed with minimal bleeding intraoperatively. Management approach of penetrating vertebral artery injury with concomitant cervical nerve root injury and the role of endovascular intervention were discussed.

Computed tomography of the carpal tunnel was performed in the hands of both patients and controls in a neutral position, in flexion and in extension. The median nerve was not compressed between the long flexors and the flexor retinaculum in either flexion or extension of the wrist. In flexion, the nerve usually moved dorsally, away from the flexor retinaculum. No difference could be found between the cross-sectional area of the carpal tunnel between patients and controls.
