However, the other studies regarding this topic had reported contradictory results. Therefore, we conducted this meta-analysis to compare the clinical results and other parameters between total hip arthroplasty following pelvic osteotomy and primary total hip arthroplasty. We systematically searched PubMed, the Cochrane Library, EMBASE, Web of Science, Scopus, EBSCO and Web of science from inception to September 2020. This study compared the outcomes between THA following previous PO and primary THA with respect to operative time, blood loss, Harris hip score (HHS), revision rates, complication rates, cup position, cup size, cup coverage and hip joint center. 14 studies with 3913 participants were included. The THA after PO group had longer operative time (MD, 13.8 mins; 95% CI, 4.73 to 22.87 mins; P=0.003), greater blood loss (MD, 82.21 ml; 95% CI, 27.94 to 136.48 ml; P=0.003), worse HHS (MD, -2.79 points; 95% CI, -4.08 to -1.50 points; P<0.00001), smaller acetabular anteversion angle (MD, -3.98°; 95% CI, -6.72 to -1.24°; P=0.004), larger cup size (MD, 1.52 mm; 95% CI, 0.75 to 2.28 mm; P=0.0001), more lateral (MD, 2.83 mm; 95% CI, 1.22 to 4.43 mm; P=0.0005) and superior (MD, 2.26 mm; 95% CI, 1.11 to 3.40 mm; P=0.0001) hip joint center. No statistically significant differences were demonstrated between the THA after PO group and primary THA group in revision rates, complication rates, acetabular abduction angle, cup coverage. THA after pelvic osteotomy was associated with inferior intraoperative outcomes, lower functional scores and worse inferior positioning of acetabular component compared with primary THA. Due to the alerted anatomical structure after PO, the findings of current study implicated that preoperative assessment such as computed tomography scan should be conducted in order to achieve satisfactory results.","PeriodicalId":7018,"journal":{"name":"Acta orthopaedica Belgica","volume":"90 3","pages":"523-533"},"PeriodicalIF":0.5,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143027663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various prophylactic methods have been evaluated, such as double antibiotic protection with intravenous Cefazolin and soaking of the transplant with vancomycin, which results in a near- zero infection rate. This soaking method has only been studied in vitro, confirming the absence of toxicity of vancomycin on tenocytes. The primary objective of our study was to assess the mechanical quality of vancomycin-soaked tendon transplants at 6 months post-operatively. The secondary objective was to assess the rate of new rupture at 1 year. This is a retrospective, single-center study including patients who underwent ACL reconstruction using a vancomycin- soaked hamstring autograft at Rennes University Hospital between December 2018 and February 2021. An objective assessment of joint laxity by means of the GNRB® at 134N was performed at 6 months post-operatively and a clinical evaluation (Lysholm and subjective IKDC questionnaires) at 1 year were performed. Fifty-three patients aged between 18 and 57 years were included. At 6 months, GNRB® of the operated knee joints was significantly different compared with the non-operated ones but was below the threshold for complete or partial rupture according to the manufacturer's clinical significance threshold (3 mm for a complete rupture and 1.5 mm for a partial rupture). At one year, 3.8% of our population had an early rupture, the reason for which was technical defects in the positioning of the graft. The stability of knees reconstructed with a Vancomycine soaked ACL graft is comparable with that of the contralateral knee with an intact ACL.

Electronic databases including Medline, Scopus, Web of Science, Cochrane library, and Embase were systematically searched for identifying relevant published studies from their inception to April 2023.

However, there is no consensus on the treatment of these fractures and their relative indications for surgery. The purpose of this study is to determine whether surgical treatment of mid-diaphyseal clavicular fractures indeed results in fewer complications and better radiological outcomes, as current trends suggest, in comparison to conservative treatment. A retrospective multicenter study was conducted between January 2005 and April 2017, involving adult patients aged 16 to 75 years with mid-diaphyseal clavicular fractures. Out of a total of 715 clavicle fractures assessed, 220 met the inclusion criteria for this study. The research encompassed a matched-pair cohort, comparing clavicle fractures treated surgically and those managed conservatively. The consolidation rate was respectively 94.5% In the operative group, and 89.1% in the conservative group. There was no statistically significant difference in terms of consolidation (p-value: 0.219). The surgical group had an infection rate of 1.8%. Additionally, 31.8% of patients experienced hardware-related discomfort, and 43.6% required a secondary surgery to remove the plate. The results of this study reveal a similar rate of consolidation between the two treatment approaches. However, there is a noticeable but not significant difference in pseudarthrosis incidence in the conservative group, which is typically asymptomatic and does not usually require surgical intervention. On the other hand, patients who have undergone osteosynthesis often experience hardware-related discomfort and may require a subsequent procedure for hardware removal. Low profile dual plating might reduce this inconvenient.","PeriodicalId":7018,"journal":{"name":"Acta orthopaedica Belgica","volume":"90 3","pages":"435-441"},"PeriodicalIF":0.5,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143027552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
