RESUMO
The Bengal tiger (Panthera tigris tigris) is a species belonging to the Felidae family. In Argentina, tigers are currently only found in captivity. The longevity of individual animals in human-controlled environments depends on proper management and practices that prioritize animal welfare. Regular veterinary care is essential to maintain optimal health conditions. Professionals must have a comprehensive understanding of the anatomy and physiology of tigers to effectively perform medical procedures and administer treatments. The study described in the text focuses on the trajectory and distribution of nerves in the pelvic limb of a Bengal tiger specimen, providing detailed dissection findings. The results revealed that the lumbosacral plexus is formed from the ventral rami of the LIV, LV, LVI, LVII, SI, SII and SIII nerves. Among the observations to highlight is the great development of the nerves N. cutaneus femoris lateralis and N. cutaneus femoris caudalis some differences were observed in the distribution of the N. femoralis and N. obturatorius; the N. ischiadicus, together with its division into the fibularis communis and tibialis nerves, showed the same configuration observed in other cats. Finally, it was observed that the nerves N. gluteus cranialis and N. gluteus caudalis also originated from the truncus lumbosacralis. The similarities and differences with studies carried out on other cats are relevant and provide anatomical data for medical procedures in the Bengal tiger.

BACKGROUND AND OBJECTIVES: Lumbosacral plexus schwannomas (LSPSs) are benign, slow-growing tumors that arise from the myelin sheath of the lumbar or sacral plexus nerves. Surgery is the treatment of choice for symptomatic LSPSs. Conventional retroperitoneal or transabdominal approaches provide wide exposure of the lesion but are often associated with complications in the abdominal wall, lumbar or sacral plexus, ureter, and intraperitoneal organs. Advances in technology and minimally invasive (MIS) techniques have provided alternative approaches with reliable efficacy compared with traditional open surgery. We describe 3 MIS approaches using tubular retractor systems according to the lesion level. METHODS: This was a multicenter, retrospective observational cohort study to evaluate the use of MIS tubular approaches for surgical resection of LSPSs. We included 23 lumbar and upper sacral plexus schwannomas. Clinical presentation, spinal level, surgical duration, degree of resection, days of hospitalization, pathological anatomy of the tumor, approach-related surgical difficulties, and outcomes were collected. RESULTS: The posterior oblique approach was used in 43.5% of the cases, the transpsoas approach in 39.1%, and the transiliac in 17.4%. The mean operative time was 3.3 hours, and the mean hospitalization was 2.5 days. All tumors were WHO grade 1 schwannoma. Postoperative MRI confirms gross total resection in 91.3% of the patients. No patient requires instrumentation. The pros and cons of each approach were summarized. CONCLUSION: The MIS approaches adapted to the lumbar level may improve surgeons' comfort allowing a safe resection of retroperitoneal LSPS.

Abstract Objective: To show the experience of a Latin American public hospital, with SNM in the management of either OAB, NOUR or FI, reporting feasibility, short to medium-term success rates, and complications. Methods: A retrospective cohort was conducted using data collected prospectively from patients with urogynecological conditions and referred from colorectal surgery and urology services between 2015 and 2022. Results: Advanced or basic trial phases were performed on 35 patients, 33 (94%) of which were successful and opted to move on Implantable Pulse Generator (GG) implantation. The average follow-up time after definitive implantation was 82 months (SD 59). Of the 33 patients undergoing, 27 (81%)reported an improvement of 50% or more in their symptoms at last follow-up. Moreover, 30 patients (90%) with a definitive implant reported subjective improvement, with an average PGI-I "much better" and 9 of them reporting to be "excellent" on PGI-I. Conclusion: SNM is a feasible and effective treatment for pelvic floor dysfunction. Its implementation requires highly trained groups and innovative leadership. At a nation-wide level, greater diffusion of this therapy among professionals is needed to achieve timely referral of patients who require it.

Morphological studies provide knowledge that allow us to understand how animals interact with the natural environment or the captivity. The goal of this study was to describe the origin and antimeric distribution of lumbosacral plexus nerves in Didelphis aurita and D. albiventris. Fourteen adult cadavers of D. aurita, seven males and seven females, and 13 adult cadavers of D. albiventris, nine males and four females were used. The specimens were sexed, identified, fixed and dissected until the origins of the lumbosacral plexus nerves were exposed. Data were represented as absolute frequency and simple percentage. The lumbosacral plexuses derived a trunk for the femoral and obturator nerves from the ventral branches of L3-L4 (75%) in D. aurita, and in D. albiventris the femoral nerve of L3-L4 (73.1%) and the obturator nerve of L3-L4 (61.5%). In both species, formation of a lumbosacral trunk derived from L5-L6-S1 occurred in 78.6% of D. aurita and 61.5% of D. albiventris. The origin and distribution of lumbosacral plexus nerves of the studied species present similarities with domestic and wild eutherian mammals.

El dolor abdominal es una de las sintomatologías que afectan con frecuencia la cavidad abdomino-pélvica. Dicha cavidad posee una inervación somática en la que intervienen del séptimo a doceavo nervios intercostales, ramos colaterales y terminales del plexo lumbar y el nervio pudendo; siendo objetivo de este trabajo la descripción anatómica del dolor abdominopélvico a través del plexo lumbar, nervios intercostales y nervio pudendo, sus diferentes patrones y variaciones de conformación, y las implicancias de éstas últimas en las distintas maniobras clínico-quirúrgicas. Se realizó un estudio descriptivo, observacional y morfométrico de la inervación somática de la cavidad abdomino-pélvica, en 50 preparaciones cadavéricas, fijadas en solución de formaldehído, de la Tercera Cátedra de Anatomía, Facultad de Medicina, Universidad de Buenos Aires, entre Agosto/2017-Diciembre/2019. La descripción clásica del plexo lumbar se encontró en 35 casos; la presencia del nervio femoral accesorio en ningún caso; así como también la ausencia del nervio iliohipogástrico en ningún caso; el nervio obturador accesorio se halló en 2 casos; el nervio genitofemoral dividiéndose dentro de la masa muscular del psoas mayor en 6 casos; el nervio cutáneo femoral lateral emergiendo únicamente de la segunda raíz lumbar en 6 casos y por último se encontró la presencia de un ramo del nervio obturador uniéndose al tronco lumbosacro en un caso. Los nervios intercostales y el nervio pudendo presentaron una disposición clásica en todos los casos analizados. Es esencial un adecuado conocimiento y descripción del plexo lumbar, nervios intercostales y nervio pudendo para un adecuado abordaje de la cavidad abdomino-pélvica en los bloqueos nerviosos.
SUMMARY: Abdominal pain is one of the symptoms that affect the abdominal-pelvic cavity. The abdominal-pelvic cavity has a somatic innervation involving the seventh to twelfth intercostal nerves, collateral and terminal branches of the lumbar plexus and the pudendal nerve. The objective of this work is the description of the lumbar plexus, intercostal nerves and pudendal nerve, its different patterns and structure variations, as well as its implications during pain management in patients. A descriptive, observational, and morphometric study of patterns and structure variations of the lumbar plexus, intercostal nerves and pudendal nerve was conducted in 50 formalin-fixed cadaveric dissections of the Third Chair of Anatomy at the School of Medicine in the Universidad de Buenos Aires from August 2017 to December/2019. The standard description of the lumbar plexus was found in 35 cases; accessory femoral nerve was not present in any of the cases; absence of the iliohipogastric nerve was also not found in any case, while the accessory obturating nerve was found in 2 cases; genitofemoral nerve dividing within the muscle mass of psoas in 6 cases; lateral femoral cutaneous nerve emerging only from the second lumbar root in 6 cases and finally, presence of a branch of the obturating nerve was found joining the lumbosacral trunk in one case. The pudendal and intercostal nerve patterns presented a typical pathway in all cases. Adequate knowledge and description of the lumbar plexus, intercostal nerves and pudendal nerve is essential for an adequate approach of the abdominal-pelvic cavity in nerve blocks.

Abstract In an attempt to improvise the analgesia in patients with femoral fractures, we aimed at depositing local anesthetic deep to anterior psoas fascia (APf) under ultrasound (US) guidance to block lumbar plexus elements which emerge lateral, anterior, and medial to the psoas major muscle. We termed this as circumpsoas block (CPB). Clinical and computed tomography contrast studies revealed that a continuous CPB infusion with a catheter provided a reliable block of the lumbar plexus elements. No adverse were events noted. We conclude that US guided CPB is a reliable technique for managing postoperative pain after surgery of femur fractures.

INTRODUCTION: joint replacement is a highly effective intervention that significantly improves the patient's quality of life, relieves symptoms, restores joint function, and improves mobility and independence. The optimal pain control after total hip replacement has become an important goal of postoperative management. The purpose of this paper is to compare periarticular infiltration (PAI) and lumbar plexus nerve block (LPNB) for the management of post-operative pain in primary total hip arthroplasty because we believe that LPNB provides better analgesic management and lower opioid consumption. We evaluated the opioid usage during hospitalization and the complications derived from either technique. MATERIAL AND METHODS: we randomized 45 patients who underwent elective total hip arthroplasty between January 2019 and January 2020. Two groups were evaluated based on the association of PAI or LPNB. Both as part of a multimodal analgesic regimen. RESULTS: a total of 45 patients were evaluated (22 PAI group, 23 LPNB group). Block group required less opioid administration (p = 0.069). Most of the patients in both groups reported mild/moderate pain. The LPNB group had lower pain scale with physiotherapy. We did not have complications derived from either technique. CONCLUSION: lumbar plexus nerve block (LPNB) in patients undergoing total hip arthroplasty provides better pain management and reduced opioid consumption compared to PAI. The performance of this technique does not delay the beginning of physiotherapy and there were not any issues with the patient's recovery.
INTRODUCCIÓN: la artroplastía es una intervención altamente eficaz que mejora de manera significativa la calidad de vida del paciente, alivia los síntomas, restaura la función articular y mejora la movilidad e independencia. El control óptimo del dolor después de la artroplastía total de cadera se ha convertido en un objetivo importante del tratamiento postoperatorio. El propósito de este trabajo es comparar la infiltración periarticular (IPA) y el bloqueo nervioso del plexo lumbar (BNPL) para el manejo del dolor postoperatorio en la artroplastía total de cadera primaria, ya que creemos que la BNPL proporciona mejor manejo analgésico y menor consumo de opioides. Se evaluó el uso de opioides durante la hospitalización y las complicaciones derivadas de cada técnica. MATERIAL Y MÉTODOS: fueron aleatorizados 45 pacientes tratados con artroplastía total de cadera electiva entre Enero de 2019 y Enero de 2020 en dos grupos: IPA o BNPL. Ambos como parte de un régimen analgésico multimodal. RESULTADOS: veintidós en el grupo IPA y 23 en el grupo BNPL. El grupo de bloqueo requirió menos administración de opioides (p = 0.069). La mayoría de los pacientes de ambos grupos reportaron dolor leve/moderado. El grupo de BNPL tuvo menor escala de dolor al realizar fisioterapia. No tuvimos complicaciones derivadas de ninguna de las técnicas analgésicas. CONCLUSIÓN: el BNPL en pacientes sometidos a artroplastía total de cadera proporciona mejor manejo del dolor y una reducción del consumo de opioides en el postoperatorio en comparación con la IPA. La realización de esta técnica no retrasa el inicio de la fisioterapia y no hubo problemas con la recuperación del paciente.

Introduction Dorsal root entry zone (DREZ) leasioning (DREZ-otomy) is considered an effective treatment for chronic pain due to spinal cord injuries, brachial and lumbosacral plexus injuries, postherpetic neuralgia, spasticity, and other conditions. The objective of the technique is to cause a selective destruction of the afferent pain fibers located in the dorsal region of the spinal cord. Objective To identify and review the effectiveness and the main aspects related to DREZ-otomy, as well as the etiologies that can be treated with it. Methods The PubMed, MEDLINE and LILACS databases were used as bases for this systematic review, having the impact factor as the selection criteria. The 23 selected publications, totalizing 1,099 patients, were organized in a table for systematic analysis. Results Satisfactory pain control was observed in 70.1% of the cases, with the best results being found in patients with brachial/lumbosacral plexus injury (70.8%) and the worst, in patients with trigeminal pain (40% to 67%). Discussion Most of the published articles observed excellent results in the control of chronic pain, especially in cases of plexus injuries. Complications are rare, and can be minimized with the use of new technologies for intraoperative monitoring and imaging. Conclusion DREZ-otomy can be considered a great alternative for the treatment of chronic pain, especially in patients who do not tolerate the side effects of the medications used in the clinical management or have refractory pain.

SUMMARY: The aim of this study was to clarify the diverse spinal compositions of the branches of the lumbar plexus in terms of their prevalence rates and thicknesses. Thirty lumbar plexuses extracted from Korean adults were used in this study. The nerve fascicles were separated and traced with the aid of a surgical microscope. The thickness of each spinal nerve component was calculated based on the mean of the largest and smallest diameters using digital calipers under the surgical microscope. The most common patterns of the spinal composition of the branches of the lumbar plexus were as follows: The iliohypogastric nerve (IHN) and the ilioinguinal nerve (IIN) arose from the ventral ramus of the first lumbar nerve (L1), the genitofemoral nerve (GFN) arose from the anterior division of the ventral ramus of the second lumbar nerve (L2), and the lateral femoral cutaneous nerve (LFCN) arose from the posterior division of the ventral ramus of theL2, the femoral nerve (FN) arose from the posterior division of the ventral ramus of L2-the fourth lumbar nerve (L4), with the thickest spinal component derived from the third lumbar nerve (L3), and the obturator nerve (OBN) arose from the anterior division of the ventral ramus of L2-L4, with the thickest spinal component derived from L3. However, when L5 constituted the FN and OBN, the thickest spinal components of the FN and OBN was L4. This morphometric study has measured the thicknesses of diverse spinal components that constitute the branches of the lumbar plexus after separating the nerve fascicles. The thicknesses of the various spinal components of these branches can be compared in order to understand which make the main and minor contributions to the lower limb.
RESUMEN: El objetivo de este estudio fue evaluar las diversas composiciones espinales de los ramos del plexo lumbar en cuanto a sus tasas de prevalencia y grosor. Se utilizaron treinta plexos lumbares extraídos de individuos adultos coreanos. Se separaron y trazaron los fascículos nerviosos por medio de un microscopio quirúrgico. El grosor de cada componente del nervio espinal se calculó con base en la media de los diámetros mayor y menor utilizando calibradores digitales bajo el microscopio. Los patrones más comunes de la composición espinal de los ramos del plexo lumbar fueron los siguientes: el nervio iliohipogástrico (NIH) y el nervio ilioinguinal (NII) surgieron del ramo ventral del primer nervio lumbar (L1). El nervio genitofemoral (NGF) surgió de la división anterior del ramo ventral del segundo nervio lumbar (L2). El nervio cutáneo femoral lateral (NCFM) surgió de la división posterior del ramo ventral L2. El nervio femoral (NF) surgió de la división posterior del ramo ventral de L2. El cuarto nervio lumbar (L4), con el componente espinal más grueso derivado del tercer nervio lumbar (L3) y el nervio obturador (NOB) surgieron de la división anterior del ramo ventral de L2-L4, con el componente espinal más grueso derivado de L3. Sin embargo, cuando L5 constituía el NF y NOB, los componentes espinales más gruesos del NF y NOB eran de L4. Este estudio morfométrico analizó los espesores de diversos componentes espinales que constituyen las ramas del plexo lumbar después de separar los fascículos nerviosos. Es posible comparar los espesores de los diversos componentes espinales de estos ramos para comprender las contribuciones principales y menores al miembro inferior.

SUMMARY: The innervation of the pelvic limbs of the Van cat is investigated in this research. The origins of the nerves, the innervated muscles and nerve diameters were shown in a table. Five cat cadavers were used in the study. The pudendal nerve originated from the S1-S2 spinal nerves. The femoral nerve consisted of the ventral branches of the 5th and 6th lumbar nerves in 4 cats The ischiatic nerve was composed of the 6th and 7th lumbar (L6-L7) and S1 spinal nerves in all cadavers. The ischiatic nerve was the thickest branch of sacral plexus (the average diameter on the right side was 3.31 ± 0.27 mm and the average diameter on the left side was 3.28 ± 0.29 mm). The lumbosacral plexus was formed by the ventral branches of the L4-S3 spinal nerves. N.genitofemoralis consisted of only the ventral branches of L4 in all cadavers. N. femoralis did not give rise to a branch to the m. iliopsoas. N.plantaris lateralis was found to give a branch to the 3th finger. The quadriceps femoris muscles did not take any branches from either the ischiadicus nerve or the pudendal nerve. The obturator nerve did not receive any branches from the L4 spinal nerves. There was no branch to the skin from the caudal gluteal nerve. The thinnest nerve was the pudendal nerve. Due to the scarcity of studies on the lumbosacral plexus of cats, it is thought that this study will complete a gap in the field of veterinary anatomy.
RESUMEN: En esta investigación se estudió la inervación de los miembros pélvicos del gato Van. Los orígenes de los nervios, los músculos inervados y los diámetros de los nervios son mostrados en una tabla. En el estudio se utilizaron cinco cadáveres de gatos. En cuatro gatosel nervio pudendo se originaba a partir de los nervios espinales S1-S2. El nervio femoral consistió en los ramos ventrales de los nervios lumbares quinto y sexto. El nervio isquiático estaba compuesto por los nervios espinales sexto y séptimo lumbar (L6-L7) y S1 en todos los cadáveres. El nervio isquiático era el ramo más grueso del plexo sacro (el diámetro medio del lado derecho medía de 3,31 ± 0,27 mm y el diámetro medio izquierdo 3,28 ± 0,29 mm). El plexo lumbosacro estaba formado por los ramos ventrales de los nervios espinales L4-S3. N. genitofemoralis constaba solo de las ramas ventrales de L4 en todos los cadáveres. N. femoralis no dio lugar a un ramo a la m. iliopsoas. Los músculos del cuádriceps femoral no tomaron ningún ramo ni del nervio isquiático ni del nervio pudendo. El nervio obturador no recibió ramos de los nervios espinales L4. No existían ramos a la piel desde el nervio glúteo caudal. El nervio más delgado fue el nervio pudendo. Debido a la escasez de estudios sobre el plexo lumbosacro de los gatos, este estudio completará un vacío en el campo de la anatomía veterinaria.

OBJECTIVE: Data concerning the surgical treatment of lumbosacral plexus tumors (LSPTs) is scarce. This study aims to present our experience with a series of 19 patients surgically treated for symptomatic LSPTs at our institution. METHODS: This is a retrospective study of 19 patients surgically treated for symptomatic LSPTs from 2011 to 2019. Clinical data were retrieved from medical records and consisted of age, gender, clinical presentation, location of the lesion, surgical approach, final histopathologic diagnosis, follow-up time, outcomes, and complications. RESULTS: Nineteen surgical procedures were conducted. Thirteen patients were female and six, male. The median age of patients was 45 years (range 20 to 63 years). No patients harbored genetic syndromes. Surgical treatment appears to be correlated to the reduction of pain in patients with peripheral nerve sheath tumors (PNSTs), as assessed by visual analog scale (VAS). Sixteen patients did not present with new-onset deficits during follow-up (84.2%), two of whom recovered from their preoperative deficit. Four patients presented with postoperative weakness. The histopathological diagnoses were 11 schwannomas, four neurofibromas, three metastases, and one lymphoma. CONCLUSIONS: LSPTs are rare. When surgical treatment is indicated, it usually requires multidisciplinary management. Surgery appears to be effective concerning the reduction of pain in PNSTs and may also recover neurological deficits. Iatrogenic neurological deficits are an evident risk, such that intraoperative multimodal monitoring should always be performed if available. In lesions involving the sacral plexus, we found it to be indispensable.

OBJECTIVE: To determine predictors of success for sacral neuromodulation in women with overactive bladder, urinary retention, and fecal incontinence. METHODS: A retrospective chart review was performed on women who underwent a staged sacral neuromodulation implantation between 2007 and 2018. Clinical and procedural characteristics were recorded. Presence of intraoperative motor responses in either all 4 or <4 electrodes were used to group women. Endpoints included completion of stage II implant, tined lead revision, and patient-reported success. RESULTS: In 198 women with a mean age of 62.9 years (SD+/- 14.7), completion of stage II implant occurred in 92.4% of women, and 83.3% of these women reported success at the first postoperative visit. Continued success at 6 months was reported in 70.3%. Lead revision was noted in 23.0%. Age >65 years (odds ratio [OR]â¯=â¯0.2, 95% confidence interval [CI]â¯=â¯0.06-0.8) and prior onabotulinumtoxinA (onaBoNT-A) (ORâ¯=â¯0.2, 95% CIâ¯=â¯0.06-0.9) were negative predictors for completion of stage II implant on multivariable analysis. Also, prior pelvic floor physical therapy was a significant negative predictor of postoperative patient-reported success on multivariable analysis (ORâ¯=â¯0.25, 95% CIâ¯=â¯0.1-0.6). There were no differences seen in women who had motor responses with either all 4 electrodes or <4 electrodes in any endpoint (P > .05). CONCLUSION: Patient age >65 and history of prior onaBoNT-A were associated with failure to complete stage II implant. Women with prior pelvic floor physical therapy were less likely to report success after sacral neuromodulation. Motor responses in <4 electrodes during lead testing did not impact patient-reported success.

CONTEXTO CLÍNICO: El dolor lumbar y la neuralgia son síntomas muy comunes con un pico de aparición entre los 45 y 60 años.1 Sólo el 20% de los casos responde a una causa identificada en la columna, como degeneración de las facetas articulares o enfermedades del disco intervertebral y de estos, se estima que aproximadamente un 5% tiene su origen en una enfermedad discal.2 En los Estados Unidos, cerca del 30% de las personas entre 30 y 50 años presentarán síntomas secundarios a patología discal; en relación a Argentina, se desconoce la prevalencia.35 Esta patología se presenta en edades laboralmente activas, lo que se asocia también a pérdidas económicas secundarias. La hernia de disco se produce cuando el núcleo pulposo (interno) de un disco intervertebral sobresale a través de una debilidad en el anillo fibroso que lo circunda. Los pacientes afectados por esta patología, Suelen presentar dolor de intensidad moderada a severa, limitación física, dificultad para realizar sus actividades habituales (incluyendo las laborales) y refieren una afectación de su calidad de vida. Si bien la mayoría de las hernias discales (90%) se resuelven con terapia conservadora, algunas
