Large bone defects resulting from osteolysis, fractures, osteomyelitis, or metastases pose significant challenges in acetabular reconstruction for total hip arthroplasty. This study aimed to evaluate the survival and radiological outcomes of an acetabular reconstruction technique in patients at high risk of reconstruction failure (i.e. periprosthetic joint infection (PJI), poor bone stock, immunosuppressed patients), referred to as Hip Reconstruction In Situ with Screws and Cement (HiRISC). This involves a polyethylene liner embedded in cement-filled bone defects reinforced with screws and/or plates for enhanced fixation. A retrospective chart review of 59 consecutive acetabular reconstructions was performed by four surgeons in a single institution from 18 October 2018 to 5 January 2023. Cases were classified based on the Paprosky classification, excluding type 1 cases (n = 26) and including types 2 or 3 for analysis (n = 33). Radiological loosening was evaluated by an orthopaedic surgeon who was not the operating surgeon, by comparing the immediate postoperative radiographs with the ones at latest follow-up. Mean follow-up was 557 days (SD 441; 31 to 1,707).Aims
Methods
The current study aimed to compare robotic arm-assisted (RA-THA), computer-assisted (CA-THA), and manual (M-THA) total hip arthroplasty regarding in-hospital metrics including length of stay (LOS), discharge disposition, in-hospital complications, and cost of RA-THA versus M-THA and CA-THA versus M-THA, as well as trends in use and uptake over a ten-year period, and future projections of uptake and use of RA-THA and CA-THA. The National Inpatient Sample was queried for primary THAs (2008 to 2017) which were categorized into RA-THA, CA-THA, and M-THA. Past and projected use, demographic characteristics distribution, income, type of insurance, location, and healthcare setting were compared among the three cohorts. In-hospital complications, LOS, discharge disposition, and in-hospital costs were compared between propensity score-matched cohorts of M-THA versus RA-THA and M-THA versus CA-THA to adjust for baseline characteristics and comorbidities.Aims
Methods
Perioperative hospital adverse events are an issue that every surgeon endeavors to avoid and minimize as much as possible. Even “minor events” such as fever or tachycardia may lead to significant costs due to workup tests, inter-consultations, and/or increased hospital stay. The objective of this study was compare perioperative outcomes (hospital length of stay [LOS], discharge disposition), rates of in-hospital adverse events and transfusion, and postoperative readmission and reoperation rates for simultaneous and staged bilateral direct anterior total hip arthroplasty (DA-THA) patients. A retrospective chart review was conducted on a consecutive series of 411 primary bilateral DA-THAs performed between 2010 and 2016 at a single institution by two fellowship trained surgeons. These were categorized as: (1) simultaneous (same anesthesia, n=122) and (2) staged (different hospitalizations, n=289). The mean time between staged surgeries was 468 days (± 414 days). Baseline patient demographics as well as hospital LOS, discharge disposition (home vs. other), hospital adverse events (i.e., nausea, vomiting, tachycardia, fever, confusion, pulmonary embolism, etc.), blood transfusions, and unplanned hospital readmissions and reoperations within 90 days were collected. Groups were compared using independent –tests, Fisher's exact test, and Pearson Chi-Square.Introduction
