The influence of adjunctive caudal epidural steroid injection on the therapeutic effect of transforaminal epidural steroid injection

Background: Epidural steroid injection is widely used to treat the short and long-term symptoms of low back and radicular pain. To the best of our knowledge, the influence of transforaminal epidural steroid injection (TFSI) combined with caudal epidural steroid injection (CESI) on pain intensity, patient satisfaction, and quality of life in lumbar radiculopathy has not been examined. Aim: To evaluate the short and long-term efficacy of TFSI, and TFSI combined with CESI (TFSI + CESI) in patients with lumbar radiculopathy. Materials and Methods: We retrospectively examined the records of 104 patients with lumbar radicular pain and L4/5 and/or L5/S1 intervertebral disc disease who underwent TFSI or TFSI + CESI. We compared the pain intensity using a Visual Numeric Scale (VNS), North American Spine Society (NASS) pain satisfaction index, and EuroQol five dimensions (EQ-5D) quality of life scores before intervention, and after 1, 6 and 12 months. Results: In the TFSI group, the mean pre-treatment VNS score was 9.2, which improved to 4.9 after 1 month and to 7.2 after 12 months. In the TFSI + CESI group, the mean pre-treatment VNS score was 9.4, which improved to 2.6 and 4.6 after 1 and 12 months, respectively. Improvement in the VNS scores was significantly higher in the TFSI + CESI group (P < 0.0001 for each). Mean EQ-5D quality of life index in the TFSI group improved from 0.59 in the pre-treatment phase to 0.76 after 12 months of intervention, while it improved from 0.62 in the pre-treatment phase to 0.84 at 12 months of intervention in the TFSI + CESI group. The EQ-5D scores were significantly better in the TFSI + CESI group at 1, 6, and 12 months after the procedure (P = 0.004, 0.036, and 0.042, for 1, 6, and 12 months, respectively). The NASS scores were significantly better in the TFSI + CESI group at 6 and 12 months after the intervention (P = 0.025 and 0.001 for 6 months and 12 months, respectively). Conclusion: In patients with lower lumbar radiculopathy, a combined TFSI + CESI technique offers superior short and long-term pain relief, quality of life, and long-term patient satisfaction, than when TFSI is performed alone

An anatomical variation of the third common digital nerve and recurrent motor branch of the median nerve

Carpal tunnel syndrome (CTS) is an entrapment neuropathy where the median nerve is compressed in the carpal canal. There are many variations of the distal branches of the median nerve at the wrist. Anatomical variations of this nerve have fundamental clinical importance to prevent injuries, especially during limited open or endoscopic surgical procedures. A case is presented of an anomalous course of the recurrent motor branch of the median nerve and high division of the third common digital nerve seen in a limited open carpal tunnel release

Intermittent priapism in degenerative lumbar spinal stenosis: Case report

BACKGROUND: Symptomatic lumbar spinal stenosis produces gradually progressive back and leg pain with standing and walking, relieved by sitting or lying. One of the uncommon symptoms is involuntary intermittent penile erection due to spinal canal stenosis. This symptom is very rare and often forgotten when history is taken

Patient Selection and Efficacy of Intradiscal Electrothermal Therapy with Respect to the Dallas Discogram Score

AIM: Intervertebral disc degeneration can cause severe low back pain. Intradiscal electrothermal therapy (IDET) is a minimally invasive treatment option for patients with symptomatic internal disc disruption unresponsive to conservative medical care. We aimed to evaluate 12-month pain and functional outcomes and predictors of clinical success in patients with discogenic back pain treated with IDET with respect to the Dallas Discogram Scale (DDS). MATERIAL and METHODS: This was a retrospective analysis of patients undergoing IDET for low back pain from 2009 through 2014 at Baskent University, Department of Neurosurgery. A total number of 120 consecutive patients data were collected retrospectively. The degree of disc degeneration was graded using the DDS during discography, and the presence of a high intensity zone (HIZ) on magnetic resonance (MR) imaging was noted. The primary outcome measure was assessment of back pain severity based on the Visual Analogue Scale (VAS); function was assessed by the Oswestry Disability Index (ODI). Follow-up examinations for ODI and VAS scores were assessed at 1, 6, and 12 months post-treatment. Outcomes were discussed with respect to morphological changes in intervertebral discs on discogram. RESULTS: There was an average 57.39% and 47.16% improvement in VAS and ODI scores, respectively, between pretreatment and 12 months follow-up (p<0.0001 for both comparisons). Predictors of 12-month clinical success was depended on DDS (p< 0.0001), a HIZ on MR imaging (p<0.0001). CONCLUSION: Durable clinical improvements can be realized after IDET in select surgical candidates with mild disc degeneration and HIZ, discography, and low-grade DDS, with more effective treatment results

Microvascular decompression as a surgical management for trigeminal neuralgia: A critical review of the literature

Trigeminal neuralgia (TN) is a common pain syndrome and is characterized by recurrent episodes of intense lancinating pain in one or more divisions of the trigeminal nerve. Neurovascular compression (NVC) has been considered as the main cause of TN in the root entry zone (REZ) of the trigeminal nerve in the cerebellopontine angle cistern. Microvascular decompression (MVD) is the surgical procedure of choice for the treatment of medically refractory TN. MVD has also been shown to provide pain relief even in patients without visible neurovascular compression. Additionally, it has been accepted that MVD can provide the highest rate of long-term patient satisfaction with the lowest rate of pain recurrence. We did, systematic review of the subject and also our own experiences

The Relationship of the Vertebral Artery with Anatomical Landmarks in the Posterior Craniovertebral Junction of Fresh Human Cadavers in the Turkish Population

AIM: Surgical anatomy concerning the posterior craniovertebral region in fresh human cadavers was studied to provide most accurate information for the surgical approach. MATERIAL and METHODS: In thirty-two fresh human cadavers, the distance from the posterior tubercle to the sulcus of vertebral artery (VA), the thickness and length of the third segment of VA (V3), the distance of C1/C2 facet to V3, the length, height and shape of the C2 ganglion to the neighboring structures, the distance from medial border of C1 lateral mass to dura mater, the distance of the transverse process of atlas to mastoid tip, the thickness of C1 posterior arcus were measured. RESULTS: There were variations of sulcus of VA in 14 of 32 cadavers (43.7%), the right VA was larger in 23 cadavers (71.8%). The ganglion was found over the C1 lateral mass screw entry point in 45 of 64 ganglions (70.31%) and below the screw entry point in 19 of 64 ganglions (29.69%). The distance of the medial border of the C1 lateral mass to dural tube was 3.81 +/- 0.55 mm at the right side and 3.91 +/- 0.59 mm at the left. The thickness of C1 posterior arch was 3.73 +/- 0.75 mm at the right side and 3.75 +/- 0.77 mm at the left. The mean distance from the transverse process of C1 to the mastoid tip was 15.82 +/- 4.49 mm at the right side and 15.46 +/- 4.38 mm at the left. CONCLUSION: This is the most comprehensive and only fresh cadaver study about this region in the literature

The microsurgical anatomy of the hypoglossal canal

The hypoglossal canal (HC) is a region of the skull base whose involvement in many pathological entities is often ignored. Adequate knowledge of the anatomy of the HC and its related bony, neural, and vascular structures is essential for surgery of lesions involving this area

Effects of arterial and venous wall homogenates, arterial and venous blood, and different combinations to the cerebral vasospasm in an experimental model

Background: Risks related to rebleeding of a ruptured intracranial aneurysm have decreased. However, ischemic neurologic deficits related to vasospasm are still the leading causes of mortality ami morbidity. It is well known that vasospasm is a dynamic process affected by various factors. The severity of vasospasm in animal models and clinical observations differ from each other. This variability has not been completely explained by blood and blood degradation products. Therefore, metabolites released from the damaged vessel wall during the bleeding are thought to play an important role in vasospasm

Is the presence of linear fracture a predictor of delayed posterior fossa epidural hematoma?

BACKGROUND: Though traumatic posterior fossa epidural hematoma (PFEDH) is rare, the associated rates of morbidity and mortality are higher than those of supratentorial epidural hematoma (SEDH). Signs and symptoms may be silent and slow, but rapid deterioration may set in, resulting in death. With the more frequent use of computed tomography (CT), early diagnosis can be achieved in patients with cranial fractures who have suffered traumatic injury to the posterior fossa. However, some hematomas appear insignificant or are absent on initial tomography scans, and can only be detected by serial CT scans. These are called delayed epidural hematomas (EDHs). The association of EDHs in the supratentorial-infratentorial compartments with linear fracture and delayed EDH (DEDH) was presently investigated. METHODS: A total of 212 patients with SEDH and 22 with PFEDH diagnosed and treated in Goztepe Training and Research Hospital Neurosurgery Clinic between 1995 and 2005 were included. Of the PFEDH patients, 21 underwent surgery, and 1 was followed with conservative treatment. In this group, 4 patients underwent surgery for delayed posterior fossa epidural hematoma (DPFEDH). RESULTS: Mean age of patients with PFEDH was 12 years, and that of the patients with SEDH was 18 years. Classification made according to localization on cranial CT, in order of increasing frequency, revealed of EDHs that were parietal (27%), temporal (16%), and located in the posterior fossa regions (approximately 8%). Fracture line was detected on direct radiographs in 48% of SEDHs and 68% of PFEDHs. Incidence of DPFEDH in the infratentorial compartment was statistically significantly higher than incidence in the supratentorial compartment (p=0.007). Review of the entire EDH series revealed that the likelihood of DEDH development in the infratentorial compartment was 10.27 times higher in patients with linear fractures than in patients with supratentorial fractures (p<0.05). CONCLUSION: DPFEDH, combined with clinical deterioration, can be fatal. Accurate diagnosis and selection of surgery modality can be lifesaving. The high risk of EDH development in patients with a fracture line in the posterior fossa on direct radiographs should be kept in mind. These patients should be kept under close observation, and serial CT scans should be conducted when necessary
