| 1 | Season of the year influences infection rates following total hip arthroplasty显示文摘AIM To research the influence of season of the year on periprosthetic joint infections.METHODS We conducted a retrospective review of the entire Medicare files from 2005 to 2014. Seasons were classified as spring, summer, fall or winter. Regional variations were accounted for by dividing patients into four geographic regions as per the United States Census Bureau(Northeast, Midwest, West and South). Acute postoperative infection and deep periprosthetic infections within 90 d after surgery were tracked. RESULTS In all regions, winter had the highest incidence of periprosthetic infections(mean 0.98%, SD 0.1%) and was significantly higher than other seasons in the Midwest, South and West(P < 0.05 for all) but not the Northeast(P = 0.358). Acute postoperative infection rates were more frequent in the summer and were significantly affected by season of the year in the West.CONCLUSION Season of the year is a risk factor for periprosthetic joint infection following total hip arthroplasty(THA). Understanding the influence of season on outcomes following THA is essential when risk-stratifying patients to optimize outcomes and reduce episode of care costs. | Samuel Rosas Alvin C Ong Leonard T Buller Karim G Sabeh Tsun yee Law Martin W Roche Victor H Hernandez | 2017 | World Journal of Orthopedics2017，8，12： | 4 |
| 2 | Ponseti method compared with soft-tissue release for the management of clubfoot:A meta-analysis study显示文摘AIM: To compare the functional outcomes of patients who underwent open surgery vs Ponseti method for the management of idiopathic clubfoot and to determine whether correlations exist between functional outcome and radiographic measurements.METHODS: A meta-analysis of the literature was conducted for studies concerning primary treatment of patients with idiopathic clubfoot. We searched PubM ed Medline, EMBASE, and the Cochrane Library databases from January 1950 to October 2011. Meta-analyses were performed on outcomes from 12 studies. Pooled means, SDs, and sample sizes were either identified in the results or calculated based on the results of each study.RESULTS: Overall, 835 treated idiopathic clubfeet in 516 patients were reviewed. The average follow-up was 15.7 years. Patients managed with Ponseti method did have a higher rate of excellent or good outcome than patients treated with open surgery(0.76 and 0.62, respectively), but not quite to the point of statistical significance(Q = 3.73, P = 0.053). Age at surgery wasnot correlated with the functional outcome for the surgically treated patients(r =-0.32, P = 0.68). A larger anteroposterior talocalcaneal angle was correlated with a higher rate of excellent or good outcomes(r = 0.80, P = 0.006). There were no other significant correlations between the functional and radiographic outcomes.CONCLUSION: The Ponseti method should be considered the initial treatment of idiopathic clubfeet, and open surgery should be reserved for clubfeet that cannot be completely corrected. | Marios G Lykissas Alvin H Crawford Emily A Eismann Junichi Tamai | 2013 | World Journal of Orthopedics2013，4，3： | 3 |
