Background There are various algorithms for the treatment of prosthetic joint infections (PJI). Currently, a two-stage hip exchange is considered the "gold standard" of care for treatment of chronic hip PJIs. However, there has been recent debate whether a one-or two-stage exchange offers the correct treatment. One-stage exchange arthroplasty has particularly gained interest due to less morbidity, mortality, and functional impairment. Methods In a retrospective case series, the outcome of patients with chronic hip PJIs treated with our one-stage exchange arthroplasty was analyzed. Between January 2015 and January 2020, eight patients underwent a one-stage exchange hip arthroplasty by a single surgeon at a single institution for a chronically infected total hip arthroplasty (THA). Original diagnosis of PJI was made in accordance with the 2011 version of the Musculoskeletal Infection Society (MSIS) criteria. The femoral stem was cemented with antibioticimpregnated cement, and the polyethylene acetabular liner was cemented directly onto the acetabular bone with antibiotic-impregnated cement. Results Of the eight patients, three were female and five were male with a mean age of 70.5 years (SD 11.2, range 53-87). Six patients (75%) had infection eradication with retention of a stable implant and no additional surgery at a mean follow-up of 35.7 months (range 17-50). One patient (12.5%) underwent closed reduction for a dislocated THA at one month; however, this patient remained infection-free at the most recent follow-up of 41 months. One patient (12.5%) who was the oldest patient (87 years) died 18 days postoperatively. Overall, all living patients (87.5%) retained their one-stage exchange THA. One patient (12.5%, CI 95% 0.3-52.7) required additional surgery in the form of a closed reduction and zero patients (0.0%, CI 95% 0.0-36.9) required additional open surgery. Conclusion Single-stage exchange arthroplasty with an antibiotic-impregnated cemented femoral stem and antibioticimpregnated cemented polyethylene acetabular liner may be a useful option for the treatment of chronic hip PJIs. Our case series provides evidence that infection eradication and function preservation are possible using our one-stage exchange arthroplasty technique in a chronically infected THA. However, a multi-center study with randomization is necessary to further validate our results.
Olecranon fractures are common and frequently require surgical intervention when they are displaced or unstable. Treatment is largely dictated by fracture type and surgeon preference. Traditional methods of fixation, including tension band wiring and locking plate fixation, have adequate union rates; however, both techniques are associated with increased reoperation rates due to symptomatic hardware. The aim of this article is to describe a technique using a lowprofile, suture anchor tension band construct for simple transverse olecranon fractures, triceps avulsions, and olecranon osteotomies. The goal of this technique is to produce stable fixation and allow early range of motion while mitigating the reoperation rate caused by symptomatic or prominent hardware with olecranon plate fixation during fracture and olecranon osteotomies.
Category: Trauma; Ankle; Ankle Arthritis; Diabetes Introduction/Purpose: What level I evidence exists to support the use of FNF for surgical management of ankle fractures in high risk patients? The purpose of this study was to compare clinical outcomes following fibular intramedullary nail fixation (FNF) and open reduction and internal fixation (ORIF) of ankle fractures. Methods: A systematic review of the current literature was performed according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Certainty of evidence reported according to GRADE (Grading of Recommendations Assessment, Development, and Evaluation). Our primary hypothesis was that patients undergoing FNF procedures to manage an ankle fracture would have significantly higher patient reported outcome scores (PROs) than patients undergoing ORIF. Primary study outcome measures were validated PROs. Secondary outcome measures included complication rate, secondary surgery rate, and bony union. Results: The primary outcome analysis revealed no evidence of a significant effect difference on Olerud and Molander Ankle Score (OMAS) PRO and no evidence of statistical heterogeneity. Secondary outcome analysis revealed a significant 0.30 (0.12-0.74 95CI) relative risk reduction for complications in FNF (P=0.008). No evidence of an effect difference for bony union. No evidence of reporting bias was appreciated. Sensitivity analyses did not significantly alter effect estimates. Conclusion: The quality of evidence is reasonably strong and likely sufficient to conclude: (1) there is likely no clinically important difference between FNF and ORIF up to 12 months post-operatively, as defined by OMS (moderate certainty); (2) surgeons may reasonably expect reduced complications in 14 out of every 100 patients treated with FNF (moderate certainty); (3) there is likely no difference in bony union (low certainty). Future studies should investigate more patient-centered outcomes and if short-term findings are durable over time if these findings apply to lower risk populations.
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.
