ResumoObjetivoAnalisar os resultados entre 1984 e 2004 em nossa instituição do tratamento cirúrgico de 69 pés equinovaros em 43 pacientes portadores de mielodisplasia segundo os critérios clínico e radiográfico.MétodosEstudo retrospectivo com análise de prontuário, radiografias e consulta com pacientes portadores de mielomeningocele que foram submetidos a correção cirúrgica de pés equinovaros. A técnica cirúrgica foi a liberação posteromediolateral (LPML)_radical associada ou não a talectomia.ResultadosA média de idade na época da cirurgia foi de quatro anos e dois meses e o seguimento médio pós‐operatório, de sete anos e dois meses. Foram encontrados resultados satisfatórios em 73,9% dos pés e insatisfatórios em 26,1% (p<0,0001).ConclusãoA deformidade residual no pós‐operatório imediato está relacionada com resultados insatisfatórios e a abertura do ângulo de Kite (talocalcaneano) nos pés submetidos somente a LPML, além do posicionamento adequado do calcâneo, nos casos em que foi feita a talectomia, é o parâmetro radiográfico relacionado aos resultados satisfatórios.AbstractObjectiveTo analyze the results from surgical treatment of 69 cases of clubfoot in 43 patients with myelodysplasia according to clinical and radiographic criteria, at our institution between 1984 and 2004.MethodsThis was a retrospective study involving analysis of medical files, radiographs and consultations relating to patients who underwent surgical correction of clubfoot. The surgical technique consisted of radical posteromedial and lateral release with or without associated talectomy.ResultsThe patients’ mean age at the time of the surgery was four years and two months, and the mean length of postoperative follow‐up was seven years and two months. Satisfactory results were achieved in 73.9% of the feet and unsatisfactory results in 26.1% (p<0.0001).ConclusionResidual deformity in the immediate postoperative period was associated with unsatisfactory results. Opening of the Kite (talocalcaneal) angle in feet that only underwent posteromedial and lateral release, along with appropriate positioning of the calcaneus in cases that underwent talectomy, was the radiographic parameter that correlated with satisfactory results

Os AINH (Antiinflamatórios não hormonais) são agentes utilizados na prática clínica que interferem no processo inflamatório pela inibição da síntese de prostaglandinas e tromboxanos. Alguns trabalhos experimentais investigaram sua ação no processo de consolidação de fraturas, por meio de estudos clínicos e histológicos, sendo escassas as análises biomecânicas. Nesse estudo foram utilizados 20 ratos da linhagem Wistar, divididos aleatoriamente em dois grupos iguais: grupo A (controle) e grupo B (tratado com diclofenaco sódico). Em ambos os grupos foram realizadas fraturas abertas, após perfuração, na tíbia direita. A administração da droga foi via intramuscular, dose única diária, por 28 dias. Os animais foram pesados semanalmente. Após o sacrifício as tíbias foram dissecadas, pesadas e submetidas a ensaio biomecânico de flexão analisando-se carga máxima, deformação e coeficiente de rigidez. Observou-se que no grupo tratado com AINH não houve aumento do peso corpóreo a partir da segunda semana e as tíbias fraturadas foram mais pesadas. Neste grupo o calo ósseo suportou menor carga máxima, apresentando maior deformação e menor coeficiente de rigidez. Nos animais tratados, o osso não fraturado também se mostrou menos rígido. Concluiu-se, nas condições estudadas, que o DS alterou o processo de consolidação e o metabolismo ósseo, levando a retardo na maturação do calo e menor rigidez do osso intacto, respectivamente.

Surgical treatment is indicated for hip dislocation in patients with cerebral palsy (CP), but it requires care due to the state of nutrition and associated clinical comorbidities. The use of resources that minimize blood loss and the need for blood transfusions are essential to avoid complications. Tranexamic acid (TXA) has been highlighted for orthopedic surgeries to control intraoperative bleeding; however, there is a lack of large studies for its use in hip surgeries in patients with CP. This study aims to evaluate the efficacy and safety of tranexamic acid to reduce bleeding in pediatric patients with cerebral palsy undergoing surgical treatment for hip instability. A sample of 31 patients with CP who underwent surgical treatment for hip dislocation (hip adductor stretching, varization osteotomy of the proximal femur and acetabuloplasty using the Dega technique) was randomly divided into groups: control (n = 10) and TXA (n = 21). Preoperative and 24 h hemoglobin concentrations, the length of hospital stay (LHS), and intraoperative bleeding (IB) were analyzed. TXA significantly reduced the IB (p = 0.02). The variance in hemoglobin concentration was lower for the TXA group, but without statistical significance (p = 0.06). There was no difference in LHS. Also, no statistical difference was observed for the number of transfusions (p = 0.08). The findings provide evidence of the effectiveness of TXA in decreasing intraoperative bleeding and its safety for use in pediatric patients with cerebral palsy.

OBJETIVO: Mostrar o planejamento pré-operatório, e os resultados do tratamento cirúrgico da luxação paralítica do quadril em pacientes com paralisia cerebral. A técnica utilizada foi a osteotomia derrotatória e varizante do fêmur proximal, associada à osteotomia do ilíaco tipo Dega, sem abertura da cápsula articular. MÉTODOS: Realizamos um estudo retrospectivo de 10 quadris em oito pacientes com paralisia cerebral tipo tetraparesia espástico, submetidos a tratamento cirúrgico entre 2003 e 2005 com a mesma técnica cirúrgica. Foram avaliados parâmetros clínicos e radiográficos pré e pós-operatórios, bem como o planejamento pré-operatório com uso do intensificador de imagem. Os parâmetros clínicos analisados foram: dor, dificuldade de higiene e dificuldade de posicionamento. Os parâmetros radiológicos foram os índices de Reimers, índice acetabular e ângulo cervicodiafisário. Estes resultados foram submetidos a análise estatística. RESULTADOS: Obtivemos bons resultados com esta técnica. Com um seguimento médio de três anos, todos os quadris estavam reduzidos na última consulta, com alto grau de satisfação dos familiares, em relação ao tratamento. Além disso, mostramos que o planejamento pré-operatório com uso do intensificador de imagem nos permite a redução e estabilização desses quadris sem a necessidade de capsuloplastia. CONCLUSÃO: Os autores concluíram que no tratamento da luxação do quadril dos pacientes com paralisia cerebral tetraparéticos espásticos com o planejamento pré-operatório, não é necessária a capsuloplastia para estabilização da articulação coxofemoral. OBJECTIVES: To show the preoperative planning and the results of surgical treatment for paralytic hip dislocation in children with cerebral palsy. The techniques used were proximal femoral varus derotation osteotomy and Dega osteotomy without opening of the joint capsule. METHODS: We performed a retrospective review of ten hips in eight patients with cerebral palsy with spastic quadriplegia treated with surgery from 2003 to 2005, by the same surgical technique. Were assessed clinical and radiological outcomes before and after surgery, as well as the preoperative planning with the use of fluoroscope. The clinical parameters analyzed were: pain, difficulty performing personal hygiene, and sitting balance. The radiological parameters were Reimer's index, acetabular index and neck-shaft angle. These results were submitted to statistical analysis. RESULTS: We obtained good results with this technique. After an average follow-up of three years, all hips were stable in the last assessment, and there was a high level of satisfaction among the families in relation to the treatment. We also show that preoperative planning with fluoroscopy enables the reduction and stabilization of the hips without the need for capsuloplasty. CONCLUSION: The authors conclude that in the treatment of hip dislocation in patients with Cerebral Palsy with spastic quadriplegia, it is not necessary to open the joint capsule to stabilize the coxofemoral joint

Introduction During open surgical dislocated hip reduction, several anatomical structures, such as the round ligament, are approached. However, there is controversy over both the possibility of preserving the ligament and its functional importance. Materials and Methods This experimental study used skeletally immature rabbits as a model for congenital hip dislocation. Thirty-six rabbits comprised the sample that was submitted to the round ligament analysis. The sample was stratified for analysis (biomechanics, zymography, histology, and immunohistochemistry). Statistical analysis compared the unstable side to the control side of each rabbit. Results Biomechanical assays showed that the mean maximal strength of the round ligament on the unstable side was similar to that of the control side (p = 0.594), which was also the case with maximum deformation (p = 0.328). Histologically, there was a statistically significant increase in cellularity on the unstable side (p <0.001). Additionally, there was significantly greater collagen occupancy on the control side (p <0.001). Zymography revealed no significant difference in the amount of active metalloproteinase 2 (MMP-2) (p = 0.068). Conclusions Although histological analysis found evidence of significant changes in the RL in unstable hips, there were no significant differences in zymography, and no changes were observed in biomechanical tests.
