RESUMO
Echinococcus granulosus infection is the primary cause of spinal hydatidosis. We describe the case of a 22-year-old man from the Brazilian Amazon region with crural spastic paraparesis and back pain. Radiological examinations showed multilocular lesions involving compression of the thoracic spine and rib injury. The patient underwent vertebrectomy with spinal stabilization and thoracoplasty with resectioning of the costal arch. Subsequently, the patient was prescribed oral treatment with albendazole. Marked recovery of the neurological status was achieved. Bone hydatid disease is rare, accounting for 0.5%-0.4% of all hydatid cysts, affecting the spine in 50% of cases. The treatment of choice is surgery accompanied by antiparasitic medication.
RESUMO
Introduction Tarsal tunnel syndrome (TTS) is caused by compression of the posterior tibial nerve. Objective To evaluate the effectiveness of surgical treatments compared to conser vative treatments in reducing the symptoms of the syndrome. Methods The PubMed, Lilacs, Cochrane Library, and PEDro databases were used for this review. Results Only 11 articles were selected. Conclusion The most common causes of TTS identified were presence of ganglia, bone prominence causing a talocalcaneal collision, trauma, varicose and idiopathic veins. The main symptom was pain in the medial plantar region and paresthesia that can radiate to the fingers or to the calf. Most patients have a positive Tinel sign upon physical examination. Electrodiagnostic test usually shows the presence of latency in sensory nerve conduction. There is no consensus suggesting that a longer time between diagnosis and surgical treatment leads to worse prognosis. In the group of operated patients, the ones who benefited most from the procedure were those who had a structure such as ganglion, cysts, or varicosities causing compression. The most cited surgical complications were postsurgical wound infection, wound dehiscence, and calcaneus hypoesthesia. Regarding surgical techniques, the release of the posterior tibial nerve via endoscopy had a favorable outcome in relation to the symptoms of pain and hypoesthesia, with no reports of infection of the operative site in the articles identified in this review. We observed a rate of good or excellent pain control of 68% (n » 204) for open surgery (n » 299), 100% (n » 8) for endoscopic surgery (n » 8), and 7% (n » 2) for conservative treatment (n » 28).
Introdução A síndrome do túnel do tarso (STT) é causada pela compressão do nervo tibial posterior. Objetivo Avaliar a eficácia dos tratamentos cirúrgicos em comparação aos conservadores na redução dos sintomas da síndrome. Métodos Foram utilizados as bases de dados PubMed, Lilacs, Cochrane Library e PEDro. Resultados Apenas 11 artigos foram selecionados. Conclusão As causas mais comuns de STT identificadas foram presença de gânglios, proeminência óssea causando colisão talocalcânea, trauma, varizes e veias. O principal sintoma foi dor na região plantar medial e parestesia, que pode irradiar para os dedos ou panturrilha. A grande maioria dos pacientes apresenta um sinal de Tinel positivo no exame físico. O teste eletrodiagnóstico geralmente mostra a presença de latência na condução nervosa sensorial. Não há consenso de que o maior tempo entre o diagnóstico e o tratamento cirúrgico leva a um pior prognóstico. No grupo de pacientes operados, os que mais se beneficiaram com o procedimento foram aqueles que apresentavam estrutura como gânglio, cistos ou varicosidades causando compressão. As complicações cirúrgicas mais citadas foram infecção da ferida operatória, deiscência da ferida e hipoestesia do calcâneo. A cirurgia endoscópica teve evolução favorável em relação aos sintomas de dor e hipoestesia, não havendo relato de infecção do sítio operatório. Observou-se que a taxa de bom ou excelente controle da dor foi de 68% (n » 204) para cirurgia aberta (n » 299), 100% (n » 8) para cirurgia endoscópica (n » 8), e 7% (n » 2) para o tratamento conservador (n » 28).
RESUMO
ABSTRACT Objective: Analyze the clinical and radiological aspects of the S2AI screw technique in patients with neuromuscular scoliosis undergoing deformity correction surgery by intraoperative navigation. Methods: Retrospective analysis of medical records of patients undergoing neuromuscular scoliosis correction surgery with the S2-alar-iliac technique between 2017-2020. Results: In the total sample of 35 patients, 18 (51.4%) were female, with an average age of 14.9. The average preoperative coronal curve was 100° ± 26.2, with an average correction of 55% ± 16.3, with an average coronal curve of 44.8°± 19.5 at the end of surgery and 45 ° ± 19.6 at the end of follow-up. The average preoperative pelvic obliquity was 27.9°± 10.9, with a correction rate of 66.1% ± 27.6, being 8.2° ± 5.4 at the end of surgery and 9 .4°± 7.0 at the end of the follow-up. The average of operated levels was 17.3± 0.7. All 70 S2 screws had a diameter of 7mm. The average duration of surgeries was 416 ± 86 minutes, with estimated intraoperative bleeding of 921 ± 394.1 ml. The average density of screws in the sample was 1.3 ± 0.2 screws per level, and the average density in the lumbosacral spine was 1.5 ± 0.2. Conclusions: Intraoperative navigation can contribute to the rate of complications related to the S2AI screw decrease; in addition, the length of this screw appears to have significant relevance in maintaining the correction throughout the follow-up. Level of evidence IV; Case series.

BACKGROUND: The phrenic nerve has been extensively reported to be a very powerful source of transferable axons in brachial plexus injuries. The most used technique used is supraclavicular sectioning of this nerve. More recently, video-assisted thoracoscopic techniques have been reported as a good alternative, since harvesting a longer phrenic nerve avoids the need of an interposed graft. OBJECTIVE: To compare grafting vs phrenic nerve transfer via thoracoscopy with respect to mean elbow strength at final follow-up. METHODS: A retrospective analysis was conducted among patients who underwent phrenic nerve transfer for elbow flexion at 2 centers from 2008 to 2017. All data analysis was performed in order to determine statistical significance among the analyzed variables. RESULTS: A total of 32 patients underwent supraclavicular phrenic nerve transfer, while 28 underwent phrenic nerve transfer via video-assisted thoracoscopy. Demographic characteristics were similar in both groups. A statistically significant difference in elbow flexion strength recovery was observed, favoring the supraclavicular phrenic nerve section group against the intrathoracic group (P = .036). A moderate though nonsignificant difference was observed favoring the same group in mean elbow flexion strength. Also, statistical differences included patient age (P = .01) and earlier time from trauma to surgery (P = .069). CONCLUSION: Comparing supraclavicular sectioning of the nerve vs video-assisted, intrathoracic nerve sectioning to restore elbow flexion showed that the former yielded statistically better results than the latter, in terms of the percentage of patients who achieve at least level 3 MRC strength at final follow-up. Furthermore, larger scale prospective studies assessing the long-term effects of phrenic nerve transfers remain necessary.

BACKGROUND: To recover biceps strength in patients with complete brachial plexus injuries, the intercostal nerve can be transferred to the musculocutaneous nerve. The surgical results are very controversial, and most of the studies with good outcomes and large samples were carried out in Asiatic countries. The objective of the study was to evaluate biceps strength after intercostal nerve transfer in patients undergoing this procedure in a Western country hospital. METHODS: We retrospectively analyzed 39 patients from 2011 to 2016 with traumatic brachial plexus injuries receiving intercostal to musculocutaneous nerve transfer in a rehabilitation hospital. The biceps strength was graded using the British Medical Research Council (BMRC) scale. The variables reported and analyzed were age, the time between trauma and surgery, surgeon experience, body mass index, nerve receptor (biceps motor branch or musculocutaneous nerve), and the number of intercostal nerves transferred. Statistical tests, with a significance level of 5%, were used. RESULTS: Biceps strength recovery was graded ≥M3 in 19 patients (48.8%) and M4 in 15 patients (38.5%). There was no statistical association between biceps strength and the variables. The most frequent complication was a pleural rupture. CONCLUSIONS: Intercostal to musculocutaneous nerve transfer is a safe procedure. Still, biceps strength after surgery was ≥M3 in only 48.8% of the patients. Other donor nerve options should be considered, e.g., the phrenic or spinal accessory nerves.

Objective To analyze 78 cases of brachial plexus injury submitted to the Oberlin technique between 2003 and 2012. The potential complications of this technique were analyzed, especially motor damage or hypoesthesia of the hand. Method Medical records from patients with brachial plexus injuries at the levels of the C5-C6 and C5-C6-C7 vertebrae were retrospectively analyzed. Cases submitted to the Oberlin procedure with or without concomitant brachial plexus procedures between 2003 and 2012 were evaluated. The minimum follow-up period was of 1 year. In addition to the clinical examination, electromyography and magnetic resonance imaging (MRI) of the brachial plexus were used to diagnose and locate the nerve damage. Results A total of 78 surgical patients met the inclusion criteria. Postoperative neurological changes, mostly transient, were observed in 18 patients. Hypoesthesia in the ulnar side of the handwas observed in seven cases; neuropathic pain in five cases; allodynia in four cases, and hand motor loss in two cases. Conclusion Based on the results of the present case series, we conclude that there are few sequelae in the donor nerve territory compared with the benefit of the Oberlin technique on the recovery of elbow flexion after brachial plexus injuries.

BACKGROUND: The phrenic nerve can be transferred to the musculocutaneous nerve using video-assisted thoracoscopy, aiming at the recovery of elbow flexion in patients with traumatic brachial plexus injuries. There are few scientific papers in the literature that evaluate the results of this operative technique. OBJECTIVE: To evaluate biceps strength and pulmonary function after the transfer of the phrenic nerve to the musculocutaneous nerve using video-assisted thoracoscopy. METHODS: A retrospective study was carried out in a sample composed of 28 patients who were victims of traumatic injury to the brachial plexus from 2008 to 2013. Muscle strength was graded using the British Medical Research Council (BMRC) scale and pulmonary function through spirometry. Statistical tests, with significance level of 5%, were used. RESULTS: In total, 74.1% of the patients had biceps strength greater than or equal to M3. All patients had a decrease in forced vital capacity and forced expiratory volume in 1 s, with no evidence of recovery over time. CONCLUSION: Transferring the phrenic nerve to the musculocutaneous nerve using video-assisted thoracoscopy may lead to an increase in biceps strength to BMRC M3 or greater in most patients. Considering the deterioration in the parameters of spirometry observed in our patients and the future effects of aging in the respiratory system, it is not possible at the moment to guarantee the safety of this operative technique in the long term.

BACKGROUND: Spinal meningiomas account for approximately 40% of intradural extramedullary tumors. As they are usually slow growing, some patients are often diagnosed late in the clinical course when they have developed myelopathy. METHODS: Here, we retrospectively studied a cohort of 51 patients undergoing surgery for spinal meningiomas. The median follow-up period was 45.9 months (range, 1-168 months). Assessment included evaluation of functional outcomes (e.g., comparison of the pre and postoperative status using the modified McCormick Functional Scale) and identification of prognostic factors. RESULTS: Seventeen patients with grade IV (McCormick Scale) neurological deficits on admission underwent surgical resection; 4 of 5 grade III (McCormick Scale) and 14 patients (Grade IV) improved within 2.11 months (mean time) postoperatively. There was no surgical mortality and the morbidity rate was 16%. CONCLUSION: Patients with advanced neurological deficits/myelopathy (Grades III or IV on the McCormick Scale) improved following surgical resection of spinal meningiomas.
RESUMO
Idiopathic spinal cord herniation is a rare cause of progressivemyelopathy, especially in the absence of a history of spinal or surgical trauma. The radiological diagnosis ismade through a myelography or an MRI exam. The spinal cord is pushed anteriorly, buffering the dural defect and leading inmost cases to Brown-Séquard syndrome. The present study describes the case of a male patient with a clinical picture of progressive thoracicmyelopathy. In the clinical and radiological investigation, an idiopathic spinal cord herniation on the chest level was identified. During the surgery, the spinal cord was reduced to the natural site, taking its usual elliptical shape, and the dural defect was repaired with a dural substitute. The numbness of the patient improved, and the shocks in the lower limbs disappeared. A postoperative MRI confirmed the surgical reduction of the herniation and the restoration of the anterior cerebrospinal fluid (CSF) column to the spinal cord. The authors describe the clinical, radiological, intraoperative, and postoperative evolution.

BACKGROUND: The phrenic nerve can be transferred to the musculocutaneous nerve in patients with traumatic brachial plexus palsy in order to recover biceps strength, but the results are controversial. There is also a concern about pulmonary function after phrenic nerve transection. In this paper, we performed a qualitative systematic review, evaluating outcomes after this procedure. METHOD: A systematic review of published studies was undertaken in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement. Data were extracted from the selected papers and related to: publication, study design, outcome (biceps strength in accordance with BMRC and pulmonary function) and population. Study quality was assessed using the "strengthening the reporting of observational studies in epidemiology" (STROBE) standard or the CONSORT checklist, depending on the study design. RESULTS: Seven studies were selected for this systematic review after applying inclusion and exclusion criteria. One hundred twenty-four patients completed follow-up, and most of them were graded M3 or M4 (70.1 %) for biceps strength at the final evaluation. Pulmonary function was analyzed in five studies. It was not possible to perform a statistical comparison between studies because the authors used different parameters for evaluation. Most of the patients exhibited a decrease in pulmonary function tests immediately after surgery, with recovery in the following months. Study quality was determined using STROBE in six articles, and the global score varied from 8 to 21. CONCLUSIONS: Phrenic nerve transfer to the musculocutaneous nerve can recover biceps strength ≥M3 (BMRC) in most patients with traumatic brachial plexus injury. Early postoperative findings revealed that the development of pulmonary symptoms is rare, but it cannot be concluded that the procedure is safe because there is no study evaluating pulmonary function in old age.

PURPOSE: Most cases of obstetric brachial plexus palsy (OBPP) involve C5 and C6 nerve roots (Erb's palsy). In those cases, re-establishing the elbow flexion is the primary goal of surgery. The partial transfer of the ulnar nerve to the musculocutaneous nerve (Oberlin's procedure) is widely used in adults, but incipient in children. The purpose of this study is to describe the results obtained with such procedure as regards the improvement of the elbow flexion and donor nerve morbidity. METHOD: Thirteen children aged 9 to 15 months underwent Oberlin's procedure. They were assessed preoperatively and 1 year postoperatively using the active movement scale and also according to the functionality of the affected limb. All of them were evaluated because of the possibility of movement loss resulting from the donor nerve. We used the non-parametric, statistic Wilcoxon signed rank test (α = 0,05) method. RESULTS: There was a significant improvement in the active elbow flexion between pre- and postoperative periods. Eleven children presented functional improvement. All of them maintained negative cookie test 1 year after the surgery. We did not observe any loss related to the donor nerve in terms of wrist flexion. CONCLUSION: The results suggest that Oberlin's procedure can be an effective and safe alternative to treat elbow flexion in Erb's palsy.

A derivação ventriculoperitoneal (DVP) representa uma forma importante e comum de tratamento da hidrocefalia. Entretanto, pode ocorrer uma série de complicações durante a sua instalação ou por causa de seu mau funcionamento, como infecção, obstrução e hiperdrenagem liquórica. Nesse trabalho, descrevemos uma rara complicação em que um paciente submetido à DVP evoluiu com tetraparesia progressiva. Investigação posterior evidenciou hiperdrenagem da válvula, levando a diminuição do retorno venoso intracraniano, dilatação do plexo venoso epidural e consequente compressão medular no nível da junção bulbomedular. Após o diagnóstico, fizemos o ajuste no nível de desempenho da válvula, e o paciente evoluiu com melhora clínica. Concluímos que o conhecimento desse tipo de complicação associada à disfunção de DVP pode levar a um diagnóstico mais precoce e melhor resposta ao tratamento. O tratamento envolve a correção do fator causal, ou seja, a hiperdrenagem...
The ventriculoperitoneal shunt represents an important and common treatment of hydrocephalus. However, there may be a number of complications during installation or due to a malfunction, such as infection, obstruction and overdrainage. In this paper, we described a rare complication in a patient submitted to a shunt who evolved to progressive tetraparesis. Further investigation showed valve overdrainage, leading to a decrease in venous return, intracranial epidural venous plexus dilatation and consequent cord compression at cervicomedullary junction. After the diagnosis, we adjusted the level of performance of the valve and the patient clinically improved. We concluded that the knowledge of this kind of complication related to shunt dysfunction may take to an early diagnosis and a better treatment response. The treatment involves correcting the causative factor which is the overdrainage...

PURPOSE: Kyphosis is a major complication of spina bifida, causing skin ulcers and osteomyelitis. This study examined the clinical and surgical characteristics of eight patients who underwent surgery, as well as improvement of their postoperative kyphosis angulations. METHOD: The authors reviewed eight cases submitted to surgery between 2006 and 2010. Surgical intervention was indicated for osteomyelitis and recurrent ulcers at the curvature apex. Osteotomies and spine stabilization were performed. The patients' clinical characteristics were analyzed, as were the surgical techniques employed, variables of surgical complications, and angle range of the kyphosis deformity postcorrection. RESULTS: There were no deaths. The average age at the time of surgery was 11 years old. The level of neurological injury was T10 in four patients and T12 in four. Average amount of bleeding during surgery was 1,442 ml, (range, 340 to 3,200 ml). Improvement of kyphosis angle was evident in all patients. The average difference between preoperative and postoperative kyphosis angle was 63.2. CONCLUSIONS: Surgery performed by a multidisciplinary team minimizes risks. Despite the high number of complications published in the literature, the results found in this study were excellent with regards to improving kyphosis angle, as well as facilitating rehabilitation and daily care of children.

UNLABELLED: Spinal cord tumors are a rare neoplasm of the central nervous system (CNS). The occurrence of metastases is related to poor prognosis. The authors analyzed one series of metastasis cases and their associated mortality. METHODS: Clinical characteristics were studied in six patients with intramedullary tumors with metastases in a series of 71 surgical cases. RESULTS: Five patients had ependymomas of which two were WHO grade III. The patient with astrocytoma had a grade II histopathological classification. Two patients required shunts for hydrocephalus. The survival curve showed a higher mortality than the general group of patients with no metastases in the CNS (p<0.0001). CONCLUSION: Mortality is elevated in patients with metastasis and greater than in patients with only primary lesions. The ependymomas, regardless of their degree of anaplasia, are more likely to cause metastasis than spinal cord astrocytomas.

Tumores da medula espinhal são neoplasias raras do sistema nervoso central (SNC). A ocorrência de metástases é relacionada a pior prognóstico. Os autores analisaram uma série de casos de metástases e a mortalidade relacionada. MÉTODO: Foram estudadas as características clínicas em seis pacientes com metástases tumorais numa série de 71 casos operados. RESULTADOS: Cinco pacientes tinham ependimomas e dois dos quais foram grau III pela classificação da OMS. O paciente portador de astrocitoma tinha classificação histopatológica de grau II. Dois pacientes necessitaram de derivação devido à hidrocefalia. A curva de sobrevivência mostrou mortalidade mais elevada no grupo de pacientes com disseminação pelo SNC (p<0,0001). CONCLUSÃO: A mortalidade, além de elevada em pacientes com metástases, é maior do que em pacientes apenas com lesão primária. Os ependimomas, independentemente do seu grau de anaplasia, costumam causar mais metástases do que os astrocitomas medulares.

PURPOSE: This study analyzed the clinical characteristics of spinal cord injury (SCI) in children 10 years of age and younger, forms of prevention, and ways to improve treatment. METHODS: Ninety-three children were reviewed between 1996 and 2009. The variables studied were type, age, cause, neurological level, association between SCI and traumatic brain injury (TBI), arthrodesis surgery, time elapsed between trauma and diagnosis, and causes of death. The statistical evaluations were done using the chi-square and ANOVA scales, in the SPSS program version 11.0. RESULTS: The most common cause was automobile crash accidents. Getting run over by a car was second (29.1 %), followed by firearm injuries (11.8 %). The thoracic spine was the most commonly impacted area. Evaluation showed that 83.9 % had complete neurological injury. Associated TBI was present in 35.5 % of the cases. Only 21.5 % of the patients required arthrodesis of the spine. In 31.2 % of the cases, myelopathy was not diagnosed at the time of the accident. There was no statistical correlation between TBI and a delayed diagnosis of SCI (p=0.231). Five children (5.4 %) died. CONCLUSIONS: The study showed that the cause of the trauma is associated to the child's age and that prevention is important. Trauma from automobile crash accidents was the main cause, and, in older children, firearm injuries are an important risk. Spinal cord injury was not always diagnosed in children at the time of accident. Educating family members and training emergency teams to adequately treat children with multiple traumas are measures that can help reduce the incidence of SCIs and neurological damage.
