Abstract:
BACKGROUND: Sciatica is a disease of the peripheral nerves. Sciatica indicates that there is damage to the peripheral nerves in the sciatic nerves. Factors that can affect this disease include gender, posture, parity, age, genetic factors, and occupation. Some of the pathophysiological conditions of sciatica include the pathology of the intervertebral disc, dorsal root, and sciatic nerve itself. The results of standard therapy with surgery have not been effective and very expensive. Therefore, research on therapy in sciatica cases still needs to be done and evaluated. Physical exercise treatment (aerobic] is necessary for this therapy in sciatica cases due to promote the function of peripheral nerves. AIM: This study aimed to determine the effect of aerobic exercise treatment on peripheral nerve injury and its relationship to walking function during injury-induced peripheral nerve regeneration. METHODS: This study was an experimental study with a post-test. he study sample consisted of Male Sprague-Dawley rats with an age of about 2-3 months divided into three groups. Control group was conducted by surgery without clamping/injuring the peripheral nerves. The treatment for second group (P1) was clamping/injury of peripheral nerve and given the treatment of physical exercise with aerobics. The treatment for third group (P2) was clamping/injury of peripheral nerve and not given the treatment of physical exercise with aerobics. The intensity of giving physical exercise treatment with aerobic that is carried out is for 42 days. Nerve functional evaluation was carried out using the sciatic function index (SFI) method. Histological staining for sciatic was used hematoxylin-Eosin (HE) staining and immunohistochemistry with Growth Associated Protein 43 (GAP43) [Bioss, bs-0154R] and S100 antibody [ab52642]. This research was approved by Animal Ethics Committee of University of Indonesia protocol (No.19-07-0852). RESULTS: There was a significant change between the 7th and 14th days (p<0.001; paired t-test) in the P1 treatment. Improvement in nerve function was found on the 14th day after being given aerobic treatment. This is indicated by the data average change in SFI scores on days 7 and 4 was from -144 to 34. This data is also supported by footprint changes for injured hindfoot data. CONCLUSION: Low intensity aerobics treatment improve the walking function and nerve function in sciatic nerve injury on day 14. This is due to the effect of physical exercise on the injured sciatic nerve.

Abstract:
Entrapment neuropathy of the sciatic nerve and pudendal nerve are painful syndromes that are often overlooked by physicians. Laparoscopic surgical interventions for nerve entrapment syndromes of the posterior pelvis focus on removing the compression lesion with the purpose of eliminating the suspected cause of sciatica, as well as pudendal neuralgia. Herein, the authors report the rare event of sciatic and pudendal nerve entrapment, which was caused by aberrant vessels and a variant piriformis muscle bundle, as a seldom-diagnosed cause of sciatica and pelvic pain, for both neurosurgeons and neuropelveologists. The authors present the laparoscopic decompression technique for the pudendal and sciatic nerves by giving our technical “tips and tricks” enriched by a surgical video.

Abstract:
Rarely, sciatica is of extraspinal aetiology. By compressing the sciatic nerve, swelling of the short external rotators of the hip can cause sciatica. Uncommon anatomical relationships between the sciatic nerve and local muscles may potentiate this compressive effect. In this report, we describe the presentation of right sciatica and foot drop resulting from both extreme local constriction and unusual anatomical variation of the right sciatic nerve.

Abstract:
Anatomical structures involving muscles and nerves in the gluteal region are important as any variations of Sciatic nerve (SN) and its surrounding muscles like piriformis muscle (PM) can lead to entrapment or compression of this nerve causing sciatica and piriformis syndrome. To find out variations in the gluteal region related to piriformis muscle and the nerves surrounding it. The study was done on 20 embalmed cadavers (total 40 gluteal regions) during routine cadaveric dissection. The anatomical relations of the piriformis and surrounding nerves i.e. sciatic nerve, its divisions and gluteal nerves were studied. The dissection was done on 40 gluteal regions. In 36 gluteal regions (90%) the sciatic nerve emerged below the piriformis as a single trunk. While in 4 gluteal regions (10%) there was a higher division of sciatic nerve. In one cadaver we observed an accessory piriformis muscle just inferior to the main piriformis muscle. The sciatic nerve was also dividing higher up into common peroneal nerve and tibial nerve in the gluteal region. The common peroneal nerve (CPN) was observed emerging between the main and the accessory piriformis muscle. Along with it the inferior gluteal nerves were also seen traversing between the main and the accessory piriformis muscle.Knowledge of anatomical variations in the gluteal region is important to explain the myalgia and neuropathies in this region. This knowledge is also important in performing hip surgeries and giving intramuscular injections in the gluteal region.

Abstract:
Objective: To assess the prevalence and clinical implications of variant sciatic nerve anatomy in relation to the piriformis muscle on magnetic resonance neurography (MRN), in patients with lumbosacral neuropathic symptoms. Materials and Methods: In this retrospective single-center study, 254 sciatic nerves, from 127 patients with clinical and imaging findings compatible with extra-spinal sciatica on MRN between 2003 and 2013, were evaluated for the presence and type of variant sciatic nerves, split sciatic nerve, abnormal T2-signal hyperintensity, asymmetric piriformis size and increased nerve caliber, and summarized using descriptive statistics. Two-tailed chi-square tests were performed to compare the anatomical variant type and clinical symptoms between imaging and clinical characteristics. Results: Sixty-four variant sciatic nerves were identified with an equal number of right and left variants. Bilateral variants were noted in 15 cases. Abnormal T2-signal hyperintensity was seen significantly more often in variant compared to conventional anatomy (40/64 vs. 82/190; p = 0.01). A sciatic nerve split was seen significantly more often in variant compared to conventional anatomy (56/64 vs. 20/190; p < 0.0001). Increased nerve caliber, abnormal T2-signal hyperintensity, and asymmetric piriformis size were significantly associated with the clinically symptomatic side compared to the asymptomatic side (98:2, 98:2, and 97:3, respectively; p < 0.0001 for all). Clinical symptoms were correlated with variant compared to conventional sciatic nerve anatomy (64% vs. 46%; p = 0.01). Conclusion: Variant sciatic nerve anatomy, in relation to the piriformis muscle, is frequently identified with MRN and is more likely to be associated with nerve signal changes and symptomatology.

Abstract:
Most of the sciatic nerve course in individuals is normal and variations in sciatic nerve is seen in approximately sixteen to twenty five percent of cases. Often sciatica is misdiagnosed. Pseudo-sciatica occurs as a result of non-spinal etiological factors. Understanding the origin and course of sciatic nerve is needed to correctly diagnose sciatica. The present study is undertaken to determine the normal course of sciatic nerve, along with its variations. Material And Methods: The following study was conducted on variation of sciatic nerve found during routine dissection of 100 cadavers for teaching purpose, in the Department of Anatomy, Govt. Medical College, Kurnool and other medical colleges in Kurnool. There were no other gross anomalies or pathologies. The skin around the area was normal and no evidence of surgery was present. The gluteal region was dissected and Gluteus maximus muscle was reflected and exposing the sciatic nerve and Piriformis muscle. Result: The incidence of variation in sciatic nerve is very low and is noted firstly in the right side of the cadaver. The occurrence of variation is 16 in 100 cadavers. Eighty four cadavers showed normal course of sciatic nerve. Out of sixteen cadavers, ten cadavers showed variation related to type b ranging 62.5% of total variations seen. Four cadavers showed type c variation ranging 25 % of total variations. Two cadavers were seen with a variation of type e ranging 12.5%. Conclusion: Sciatic nerve is the thickest, largest and longest nerve in the body. Its pathologies are also frequent in occurrence in daily life. A thorough knowledge of its anatomy and variations of sciatic nerve is required to give proper treatment plan to the patient. Also the, significance of it should not be overlooked during surgical and popliteal nerve block anaesthetic procedures.

Abstract:
Sciatic nerve endometriosis (EM) is a rare presentation of retroperitoneal EM. The authors present 2 cases of catamenial sciatica diagnosed as sciatic nerve EM. They propose that both cases can be explained by perineural spread of EM from the uterus to the sacral plexus along the pelvic autonomie nerves and then further distally to the sciatic nerve or proximally to the spinal nerves. This explanation is supported by MRI evidence in both cases. As a proof of concept, the authors retrieved and analyzed the original MRI studies of a case reported in the literature and found a similar pattern of spread. They believe that the imaging evidence of their institutional cases together with the outside case is a very compelling indication for perineural spread as a mechanism of EM of the nerve.

Fifty-two lower limbs (93%) showed normal anatomy of the sciatic nerve. Four regions (7.1%) showed variations in the morphology of the sciatic nerve. Of these, one (1.8%) showed a variation of the sciatic nerve with the piriformis muscle. This single case showed a common peroneal nerve emerging on the left between the heads of a double piriformis muscle - a variant not described in the original Beaton and Anson classification, with the tibial nerve deep to the muscle. In two other limbs, the sciatic nerves showed a normal relationship with the piriformis, but had variations in the bifurcation loci (bilateral). The divisions were in upper third and middle third of the right and left thighs respectively.</p><p><strong>Conclusion</strong>. Knowledge of the level of bifurcation and distribution of the sciatic nerve and its location is important. This nerve is commonly encountered by neurologists, orthopaedics, and anaesthesiologists. The uncommon anatomical findings described are relevant to surgeons to enable them to perform efficient surgical procedures and avoid errors.</p><p>Sciatic Nerve; Bifurcation Loci; Piriformis; Sciatica</p>

Abstract:
Background: Sciatica is typically caused by disc herniations or spinal stenosis. Extraspinal compression of the sciatic nerve is less frequent. Case Description: We report a rare case of sciatica with compression of the sciatic nerve by a low-flow vascular malformation in a 24-year-old female patient. The special feature of this case was sciatica along the S1 dermatome, which only occurred in the sitting position and inclination because of compression of the sciatic nerve between the vascular malformation and the lesser trochanter. Spinal imaging showed no abnormal findings. Surgery was performed interdisciplinary and included neurosurgery, vascular surgery, and trauma surgery. After surgery, the patient became symptom-free. Conclusion: Rare and extraspinal causes of local compression of the sciatic nerve should be considered, especially in cases of lacking spinal imaging correlation and untypical clinical presentation. Interdisciplinary surgical cooperation is of special value in cases of rare entities and uncommon locations.

Abstract:
Peripheral nerve damage affects hundreds of thousands of people every year. This study tested the effectiveness of using lysophosphatidylcholine (LPC) in combination with nerve growth factor (NGF) to increase the healing rate of damaged left sciatic nerves in female rats. The rats were randomly divided into eight groups: Sham, Right Sciatic, Crush, LPC, LPC-NGF, Crush- LPC, Crush-NGF, and Crush-LPC-NGF. The healing of the nerves was measured by monitoring gait, electrophysiological parameters (compound muscle action potential amplitudes and nerve conductance velocities) and morphological parameters (total fascicular area, total myelinated fiber counts, fiber densities, fiber diameters, and g-ratio). Gait and electrophysiological parameters were measured three times a week. Morphological parameters were measured at three weeks and at six weeks. The LPC and LPC-NGF groups were not statistically different from the controls (Sham and Right Sciatic) at either of the morphological time points but were statistically different from the controls for the first three weeks for the electrophysiological parameters and gait. The LPC-NGF group did not differ from the LPC group at any time point for any of the parameters. Crush, Crush-LPC, Crush-NGF, and Crush-LPC-NGF groups statistically differed from the controls at week 3 for all parameters and only in the electrophysiological parameters at week 6. Crush-LPC, Crush-NGF, and Crush-LPC-NGF did not differ from each other or from the Crush group. The combination of LPC and NGF did not prove to be an effective treatment for peripheral nerve damage. Future work is recommended to test multiple injections of LPC and NGF.

Abstract:
Electrical injury is known to alter the normal physiological function of nerves. In most cases, the change in function is only minor, but in severe instances the physiological function may be lost entirely. The changes in function involve the ability of the nerve to transmit an impulse, which is a function of the nerve's ability to create and maintain an electrical gradient across its membrane. When the nerve is exposed to an electrical current, the ability to maintain an electrical gradient across the membrane is reduced or lost. This change may be transient or permanent. The changes in the gradient hinder the nerve from propagating the impulse, which is the means of information transfer to and from the CNS (central nervous system). Due to the manner in which human victims are typically exposed to an electric shock, the peripheral axons usually display the greatest change in physiological function.

Abstract:
Thesis advisor: Thomas N. Seyfried
GM1 gangliosidosis is a glycosphingolipid lysosomal storage disease caused by a genetic deficiency of acid b-galactosidase (β-gal), the enzyme that catabolyzes GM1 within lysosomes. Accumulation of GM1 and its asialo form (GA1) occurs primarily in the brain, leading to progressive neurodegeneration and brain dysfunction. Less information is available on the neurochemical pathology in optic nerve and sciatic nerve of GM1- gangliosidosis. Here we analyzed the lipid content and myelin structure in optic and sciatic nerve in 7 and 10 month old normal β-gal (+/?) and GM1-gangliosidosis β-gal (-/-) mice. Optic nerve weight was lower in the β-gal -/- mice than in unaffected β-gal +/? mice, but no difference was seen between the normal and the β-gal -/- mice for sciatic nerve weight. The concentrations of GM1 and GA1 were significantly higher in optic nerve and sciatic nerve in the β-gal -/- mice than in β-gal +/? mice. The content and composition of myelin-enriched cerebrosides, sulfatides, plasmalogen ethanolamines were significantly lower in optic nerve of β-gal -/- mice than in β-gal +/? mice, however cholesteryl esters were enriched in the β-gal -/- mice. No significant abnormalities in these myelin enriched lipids were detected in sciatic nerve of the β-gal -/- mice. The abnormalities in GM1 and myelin lipids in optic nerve of β-gal -/- mice were also associated with abnormalities in the X-ray diffraction pattern including myelin content in fresh nerves [M/(M +B)] and periodicity (d). With the exception of a slight reduction in myelin content, no abnormalities in the X-ray diffraction pattern were observed in sciatic nerve of β-gal -/- mice. The results indicate that neurochemical pathology is greater in optic nerve than in sciatic nerve of β-gal -/- mice

Abstract:
Transplantation of olfactory ensheathing cells (OECs) into injured spinal cord results in improved functional outcome through axonal regeneration, remyelination, and neuroprotection. However, because little is known of the fate of OECs transplanted into injured peripheral nerve, their myelin forming potential requires investigation. To study these issues OECs were isolated from the olfactory bulbs of adult green fluorescent protein (GFP)-expressing transgenic rats and transplanted into a sciatic nerve crush lesions. Five weeks to six months after transplantation the nerves were studied histologically and it was determined that GFP-expressing OECs survived in the lesion and distributed longitudinally across the lesion zone. Immunostaining revealed a high density of isoform Nav1.6 at the newly formed nodes of Ranvier which were flanked by paranodal Caspr staining. Immuno-electron microscopy for GFP revealed transplanted OECs form peripheral type myelin. These results indicate that transplanted OECs extensively integrate into transected peripheral nerve, form myelin on regenerated peripheral nerve fibers, and reconstruct nodes of Ranvier with proper sodium channel structure.

Abstract:
Previous studies have suggested that sympathetic sprouting in the periphery may contribute to the development and persistence of sympathetically-maintained pain in animal models of neuropathic pain. The purpose of this thesis was to examine morphological changes in the cutaneous innervation in rats after chronic constriction injury (CCI) to the sciatic nerve. More specifically, this study addresses the question of whether sympathetic fibres sprout de novo into the upper dermis of the rat hindpaw skin after CCI of the sciatic nerve. We also determined changes in peptidergic sensory innervation following CCI.
At several periods post-injury, hind paw skin was harvested and processed using a monoclonal antibody against dopamine-beta-hydroxylase to detect sympathetic fibres and a polyclonal antibody against calcitonin gene-related peptide to identify peptidergic sensory fibres. We observed migration and branching of sympathetic fibres into the upper dermis of the hind paw skin, from where they were normally absent. This migration was first detected at 2 weeks, peaked at 4 to 6 weeks and lasted for at least 20 weeks post-lesion. At 8 weeks post-lesion, there was a dramatic increase in the density of peptidergic fibres in the upper dermis. Quantification revealed that densities of peptidergic fibres 8 weeks post-lesion were significantly above levels of sham animals. Interestingly, the ectopic sympathetic fibres did not innervate blood vessels but formed a novel association and wrapped around sprouted peptidergic nociceptive fibres. Our data show a long-term sympathetic and sensory innervation change in the rat hind paw skin after the chronic constriction injury. This novel fibre arrangement after nerve lesion may play an important role in the development and persistence of sympathetically-maintained neuropathic pain after partial nerve lesions.

Abstract:
Introduction: Schwannoma is the most common benign tumor of the peripheral nerve sheath. They appear in the sheath of the nervous fascicle and are well-defined masses, which allow their dissection of the underlying neural bundle. Sciatic nerve involvement is rare, accounting for less than 1%. Case report: Male, 83. He has had sciatica on the left for 10 months. With progression of pain, VAS of 9 and difficulty to walk for 1 month after admission. On physical examination, a positive tinel sign in the left gluteal region with tactile perception of nodular lesion in sciatic nerve topography. Preserved and discrete hypoesthesia strength in left sciatic nerve territory. MRI shows nodular lesion, suggestive of neural sheath tumor. Undergoing a surgical procedure for excision of the lesion. Total resection of the lesion was performed with no changes in monitoring potential. The patient was discharged from the hospital the next day, with a VAS of 0, with no other complaints and pain control. Discussion: Schwannomas have a long subclinical course, their clinical presentation is usually misleading. The referred patient started with sciatica, with painful progression to VAS 9. The diagnoses of sciatic nerve schwannomas are made with MRI. The definitive diagnosis is possible after the histopathological study. The treatment of this tumor is by massive excision and preservation of the nerve. Conclusion: Studies regarding sciatic nerve Schwannoma are scarce. There is a need for further studies on the case, to train health professionals to recognize and effectively treat the pathology.

Abstract:
The bi-layer poly-L-lactic acid (PLLA) guide tube for peripheral nerve regeneration was developed by electrospinning method to enhance axonal extension. The inner layer of the guide tube had unidirectional nanofiber and Ile-Lys-Val-Ala-Val (IKVAV) modified surface. IKVAV modified unidirectional fiber sheets which had different fiber diameters from 400 to 1200 nm were fabricated to optimize fiber diameter of the guide tube for axonal extension. Fiber sheets without the IKVAV were prepared as the control group. PC12 cells seeded on the fiber sheets were cultured for 6 days. Axons were most extended in fiber diameter of 1090 nm with IKVAV and 1160 nm without IKVAV. Maximum axon length increased by about 25% due to IKVAV modification. The bi-layer guide tube which had fiber diameter about 1133 nm was fabricated. It was confirmed that the inner layer had unidirectional fibers and the outer layer had random fibers in the guide tube. CS, which corresponds to radial compressive stiffness, of the guide tube and the sciatic nerve were 230 N/mm2 and 1.64 N/mm2 respectively. Since radial compressive stiffness of the guide tube was higher than that of the sciatic nerve, the developed guide tube was expected to enhance axonal extension without narrowing.

Abstract:
Previous research has demonstrated the use of single-channel porcine-derived urinary bladder matrix (UBM) conduits in segmental-loss, peripheral nerve repairs as comparable to criterion-standard nerve autografts. This study aimed to replicate and expand upon this research with additional novel UBM conduits and coupled therapies. Fifty-four Wistar Albino rats were divided into 6 groups, and each underwent a surgical neurectomy to remove a 7-millimeter section of the sciatic nerve. Bridging of this nerve gap and treatment for each group was as follows: i) reverse autograft—the segmented nerve was reversed 180 degrees and used to reconnect the proximal and distal nerve stumps; ii) the nerve gap was bridged via a silicone conduit; iii) a single-channel UBM conduit; iv) a multi-channel UBM conduit; v) a single-channel UBM conduit identical to group 3 coupled with fortnightly transcutaneous electrical nerve stimulation (TENS); vi) or, a multi-channel UBM conduit identical to group 4 coupled with fortnightly TENS. The extent of nerve recovery was assessed by behavioural parameters: foot fault asymmetry scoring measured weekly for six weeks; electrophysiological parameters: compound muscle action potential (CMAP) amplitudes, measured at weeks 0 and 6; and morphological parameters: total fascicle areas, myelinated fiber counts, fiber densities, and fiber sizes measured at week 6. All the above parameters demonstrated recovery of the test groups (3-6) as being either comparable or less than that of reverse autograft, but none were shown to outperform reverse autograft. As such, UBM conduits may yet prove to be an effective treatment to repair relatively short segmental peripheral nerve injuries, but further research is required to demonstrate greater efficacy over nerve autografts.
