Patient-Reported Outcome questionnaires for hip arthroscopy: a systematic review of the psychometric evidence

Abstract Background Hip arthroscopies are often used in the treatment of intra-articular hip injuries. Patient-reported outcomes (PRO) are an important parameter in evaluating treatment. It is unclear which PRO questionnaires are specifically available for hip arthroscopy patients. The aim of this systematic review was to investigate which PRO questionnaires are valid and reliable in the evaluation of patients undergoing hip arthroscopy. Methods A search was conducted in Pubmed, Medline, CINAHL, the Cochrane Library, Pedro, EMBASE and Web of Science from 1931 to October 2010. Studies assessing the quality of PRO questionnaires in the evaluation of patients undergoing hip arthroscopy were included. The quality of the questionnaires was evaluated by the psychometric properties of the outcome measures. The quality of the articles investigating the questionnaires was assessed by the COSMIN list. Results Five articles identified three questionnaires; the Modified Harris Hip Score (MHHS), the Nonarthritic Hip Score (NAHS) and the Hip Outcome Score (HOS). The NAHS scored best on the content validity, whereas the HOS scored best on agreement, internal consistency, reliability and responsiveness. The quality of the articles describing the HOS scored highest. The NAHS is the best quality questionnaire. The articles describing the HOS are the best quality articles. Conclusions This systematic review shows that there is no conclusive evidence for the use of a single patient-reported outcome questionnaire in the evaluation of patients undergoing hip arthroscopy. Based on available psychometric evidence we recommend using a combination of the NAHS and the HOS for patients undergoing hip arthroscopy.</p

The effect of type of femoral component fixation on mortality and morbidity after hip hemiarthroplasty:A systematic review and meta-analysis

Background: Hip hemiarthroplasty is a well-established treatment of displaced femoral neck fracture, although debate exists over whether cemented or uncemented fixation is superior. Uncemented prostheses have typically been used in younger, healthier patients and cemented prostheses in older patients with less-stable bone. Also, earlier research has suggested that bone cement has cytotoxic effects and may trigger cardiovascular and respiratory adverse events. Questions/Purposes: The aim of this systematic review and meta-analysis was to compare morbidity and mortality rates after cemented and uncemented hemiarthroplasty for the treatment of displaced femoral neck fractures in elderly patients. Methods: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched seven medical databases for randomized clinical trials and observational studies. We compared cemented and uncemented hemiarthroplasty using the Harris Hip Score (HHS), as well as measures of postoperative pain, mortality, and complications. Data were extracted and pooled as risk ratios or standardized mean difference with their corresponding 95% confidence intervals in a meta-analysis model. Results: The meta-analysis included 34 studies (12 randomized trials and 22 observational studies), with a total of 42,411 patients. In the pooled estimate, cemented hemiarthroplasty was associated with less risk of postoperative pain than uncemented hemiarthroplasty. There were no significant differences between groups regarding HHS or rates of postoperative mortality, pulmonary embolism, cardiac arrest, myocardial infarction, acute cardiac arrhythmia, or deep venous thrombosis. Conclusions: While we found that cemented hemiarthroplasty results in less postoperative pain than uncemented hemiarthroplasty in older patients with femoral neck fracture, the lack of significant differences in functional hip scores, mortality, and complications was surprising. Further high-level research is needed

Sporting and physical activity following hip resurfacing

The aim of this study was to assess sporting and physical activities in patients who had undergone hip resurfacing. Our study included 117 patients who underwent hip resurfacing between 2003 and 2008. University of California at Los Angeles (UCLA) activity level and Oxford hip scores (OHS) were used. Sporting and physical activities of all patients were analysed pre- and postoperatively. The mean age at surgery was 54 years. The mean follow up was 30 months. There was statistically significant improvement in UCLA activity scores from 4.4 to 6.8 (p < 0.05) and Oxford hip scores from 43.4 to 17.7 following surgery. Eighty-seven percent of patients continued to take part in sporting activities following hip resurfacing. Our study has demonstrated that hip resurfacing can allow patients to remain extremely active

Biópsia percutânea por agulha grossa de tumores de partes moles guiada por tomografia computadorizada: resultados e correlação com análise da peça cirúrgica

OBJETIVO: Avaliar a eficácia da biópsia percutânea por agulha grossa (BPAG) de tumores de partes moles guiada por tomografia computadorizada (TC), em relação ao sucesso na obtenção de amostra para análise, e comparar o diagnóstico da BPAG com o resultado anatomopatológico da peça cirúrgica, quando disponível. MATERIAIS E MÉTODOS: Foram revisados os prontuários e laudos diagnósticos de 262 pacientes com tumores de partes moles submetidos a BPAG guiada por TC em um centro de referência oncológico entre 2003 e 2009. RESULTADOS: Das 262 biópsias realizadas, foi possível a obtenção de amostra adequada em 215 (82,1%). Os tumores mais prevalentes foram os sarcomas (38,6%), carcinomas metastáticos (28,8%), tumores mesenquimais benignos (20,5%) e linfomas (9,3%). Foi possível realizar graduação histológica em 92,8% dos pacientes com sarcoma, sendo a maioria (77,9%) classificada como alto grau. Do total de pacientes, 116 (44,3%) realizaram cirurgia para exérese e confirmação diagnóstica. A BPAG mostrou acurácia de 94,6% na identificação de sarcomas, com sensibilidade de 96,4% e especificidade de 89,5%. A graduação histológica teve concordância significativa entre a BPAG e a peça cirúrgica (p < 0,001; kappa = 0,75). CONCLUSÃO: A BPAG guiada por TC demonstrou elevada acurácia diagnóstica na avaliação de tumores de partes moles e na graduação histológica dos sarcomas, permitindo um adequado planejamento terapêutico
