Eficácia, segurança e custo-efetividade comparada de tratamentos cirúrgicos e conservadores de fratura de úmero proximal: revisão rápida de evidências / Comparative effectiveness, safety and cost-effectiveness between surgical and conservator treatments for proximal humeral fracture: a rapid review of evidence

Tecnologia: Hemiprótese de ombro ajustável. Próteses de cabeça excêntrica reproduzem a anatomia da extremidade proximal do úmero. Indicação: Reconstrução da extremidade proximal do úmero no tratamento de fraturas complexas de úmero. Pergunta: o tratamento cirúrgico é superior ao tratamento conservador, para tratamento de fratura proximal de úmero, com melhores desfechos funcionais, menos complicações, menor mortalidade? Os efeitos terapêuticos da prótese de ombro excêntrica são superiores aos da prótese de ombro Neer II em pacientes com fratura proximal de úmero submetidos a hemiartroplastia de ombro nos desfechos de resultados funcionais e complicações cirúrgicas? Métodos: Levantamento bibliográfico foi realizado em bases de dados Pubmed, BVS e Google com estratégias estruturadas de busca. Foi feita avaliação da qualidade metodológica das revisões sistemáticas com a ferramenta AMSTAR e para os estudos econômicos, foi utilizado o QHES checklist. Resultados: Foram identificados 485 registros nas bases de dados internacionais e nacionais. Após a remoção de duplicatas e exclusão dos não elegíveis, pela análise de título e resumo, foram selecionadas quatro revisões sistemáticas e um estudo econômico. Conclusão: Não há evidências suficientes de ensaios clínicos para informar qual a melhor escolha entre as intervenções (não cirúrgicas, cirúrgicas ou de reabilitação) para essas fraturas. Não foram encontrados estudos brasileiros sobre eficácia e custo-efetividade das diferentes abordagens cirúrgicas bem como os tipos e marcas de próteses entre si

Technology: Adjustable shoulder hemi prosthesis. Eccentric head prostheses reproduce the anatomy of the proximal extremity of the humerus. Indication: Reconstruction of the proximal extremity of the humerus in the treatment of complex humerus fractures. Question: Is surgical treatment superior to conservative treatment, for the treatment of proximal humerus fractures, with better functional outcomes, less complications, less mortality? Are the therapeutic effects of the eccentric shoulder prosthesis superior to those of the Neer II shoulder prosthesis in patients with proximal humerus fractures who underwent shoulder hemiarthroplasty in the outcomes of functional results and surgical complications? Methods: Bibliographic survey was carried out in Pubmed, BVS and Google databases with structured search strategies. The methodological quality of systematic reviews was assessed using the AMSTAR tool and for economic studies, the QHES checklist was used. Results: Were they identified 485 records in international and national databases. After removing duplicates and excluding the ineligible ones, by analyzing the title and summary, four systematic reviews and one economic study were selected. Conclusion: There is not enough evidence of clinical trials to inform which is the best choice between interventions (nonsurgical, surgical or rehabilitation) for these fractures. No brazilian studies were found about the efficacy and cost-effectiveness of the different surgical approaches, as well as the types and brands of prostheses between them

Influence of Glenosphere Design on Outcomes and Complications of Reverse Arthroplasty: A Systematic Review

BACKGROUND: Different implant designs are utilized in reverse shoulder arthroplasty. The purpose of this systematic review was to evaluate the results of reverse shoulder arthroplasty using a traditional (Grammont) prosthesis and a lateralized prosthesis for the treatment of cuff tear arthropathy and massive irreparable rotator cuff tears. METHODS: A systematic review of the literature was performed via a search of two electronic databases. Two reviewers evaluated the quality of methodology and retrieved data from each included study. In cases where the outcomes data were similar between studies, the data were pooled using frequency-weighted mean values to generate summary outcomes. RESULTS: Thirteen studies met the inclusion and exclusion criteria. Demographics were similar between treatment groups. The frequency-weighted mean active external rotation was 24° in the traditional group and 46° in the lateralized group (p = 0.0001). Scapular notching was noted in 44.9% of patients in the traditional group compared to 5.4% of patients in the lateralized group (p = 0.0001). The rate of clinically significant glenoid loosening was 1.8% in the traditional group and 8.8% in the lateralized group (p = 0.003). CONCLUSIONS: Both the traditional Grammont and the lateralized offset reverse arthroplasty designs can improve pain and function in patients with diagnoses of cuff tear arthropathy and irreparable rotator cuff tear. While a lateralized design can result in increased active external rotation and decreased rates of scapular notching, there may be a higher rate of glenoid baseplate loosening.
