Chronic postoperative osteomyelitis represents an important health problem due to its significant morbidity and low mortality rate. This pathology is challenging because of difficulties in understanding the pathogenesis and the decision-making involving the treatment. The present article had the goal of reviewing the definition, pathogenesis, clinical aspects, diagnosis, and treatment of chronic postoperative osteomyelitis, and of gathering this information in a single Brazilian updated publication.The PubMed, LILACS, and the Cochrane Library medical databases were analyzed using pertinent keywords. Current and relevant articles were selected.The present article gathered the established information, as well as innovations related to chronic osteomyelitis and its treatment, to offer updated data to assist the professionals involved in the management of chronic osteomyelitis.
Resumo Objetivo Avaliar o impacto da graduação da doença degenerativa lombar (DDL) sobre o alinhamento sagital espinopélvico. Métodos Ao todo, 130 pacientes (dade média: 57 anos; 75% do sexo feminino) com dor lombar associada a DDL foram prospectivamente incluídos. A gravidade da DDL foi definida pelos seguintes achados nas radiografias anteroposterior e de perfil da coluna lombar: osteofitose; perda de altura do disco intervertebral; esclerose na placa vertebral terminal; número de segmentos afetados; deformidades; e instabilidade objetiva. Os pacientes foram graduados segundo a DDL da seguinte maneira: grau 0–ausência de sinais de DDL na coluna lombar; grau I – sinais de DDL em até dois segmentos; grau II – envolvimento em três ou mais segmentos; grau III – quando associada a escoliose, espondilolistese ou laterolistese. Parâmetros radiográficos espinopélvicos, como incidência pélvica (IP), lordose lombar (LL), discrepância entre a IP e a LL (IP-LL), versão pélvica (VP), e eixo vertical sagital (EVS) foram analisados de acordo com os graus de DDL. Resultados Houve diferença nos parâmetros radiográficos comparando-se os graus de DDL, com os pacientes de grau III apresentando maiores valores de EVS (p = 0,001) e VP (p = 0,0005), o que denota maior inclinação anterior do tronco e maior retroversão pélvica do que os pacientes de graus 0 e I. Pacientes de grau III também apresentaram maiores valores de IP-LL, o que denota perda da lordose relativa ao valor da IP, do que pacientes grau I (p = 0,04). Conclusão Pacientes com DDL mais grave demonstraram uma tendência a maior desalinhamento sagital espinopélvico comparados com pacientes com graus mais leves.
Objective: To evaluate the impact of the severity of degenerative lumbar disease (DLD) on the occurrence of spinal deformity, as well as on the choice of treatment, whether conservative or surgical. Methods: This is a retrospective analysis of a prospective database. One hundred and thirty patients with low back pain and/or pain radiating to the lower limbs were included in the study and were graded on a DLD scale that considers total spine (panoramic) X-ray findings. The rates of adult spinal deformity (ASD) for the different degrees of the DLD scale were compared using the Chi-square test. The choice of treatment type, conservative or surgical, was also compared among the degrees of the DLD scale using Fisher's exact test. Results: The ASD rate was zero in grade 0 patients, 24% in grade I, 35% in grade II and 44% in grade III (P = 0.02). Grade III patients were more likely to be diagnosed with ASD (OR = 2.22; P <0.05; 95% CI = 0.90-5.45) compared to the other DLD grades. Only 7.7% of the patients were chosen for surgical treatment and there was no difference by the DLD scale grade. Conclusion: There was correlation between the DLD grading scale and the occurrence of ASD, with at least twice the chance of this diagnosis in DLD scale grade III as compared to the other grades. The treatment of choice was conservative in a very small number of patients analyzed, with no difference between the different grades of the DLD grading scale. Level of Evidence III; Retrospective analysis of prospective database (cohort).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
