Compared to modern uncemented femoral stem designs, cemented stems yield lower rates of periprosthetic fracture requiring re-operation, without increasing risk of all-cause mortality. Tapered-wedge stems had similar rates of re-operation due to periprosthetic fracture as reamed uncemented stems.
The association between donor-specific human leukocyte antigen (HLA) antibody formation and small bone allograft resorption has not been studied. We present the case of a patient treated for glenoid bone loss using a distal tibial allograft with Bankart repair who formed donor-specific HLA antibodies against the allograft and had subsequent graft resorption. X-ray and computed tomography (CT) scans were performed before and after surgery at standard checkpoints. Patient blood and serum samples were collected before and after surgery for HLA typing and HLA antibody testing. Human leukocyte antigen antibodies against the donor-specific HLA-A2 antigens were identified 6 weeks after surgery and were still detected at 5 months after surgery. At 6 months after surgery, a CT arthrogram revealed significant graft resorption. This case shows a temporal correlation between HLA antibody formation and clinical findings, potentially suggesting an association between HLA antibody formation and graft resorption. Further study is required to confirm this.
Objective: The purpose of this meta-analysis was to determine whether perioperative fascia iliaca compartment blockade (FICB) decreases mortality in patients with hip fracture. Methods: MEDLINE (PubMed and Ovid platforms), Web of Science, EMBASE, and Cochrane Database of Systemic Reviews were screened for "fascia iliaca compartment block, hip fracture" articles in English, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, from January 1, 2005, to March 1, 2020. All relevant randomized controlled trials and cohort and case-control studies were included for analysis. Relevant article titles were identified, and their corresponding abstracts were independently reviewed by two authors for inclusion. The full-text articles were then obtained for all relevant identified abstracts and assessed for inclusion in the meta-analysis. Conflicts in quality assessment between the two independent reviewers were resolved by a consensus vote of all authors.Results: Study quality was assessed objectively using the Jadad and Newcastle-Ottawa Scale. This meta-analysis was done in accordance with the PRISMA (http://links.lww.com/JAAOS/A731) and QUORUM guidelines. Quantitative synthesis analysis was done using Cochrane Reviews Review Manager (version 5.3). All analyses were completed using random-effects models and comparing the individual effect sizes within each study. Discussion: Management of hip fracture pain with FICB does not markedly decrease short-term mortality. Our findings support the continued use of FICB for the management of hip fractures in geriatric patients and suggest the need for future prospective randomized
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.
