Spinal anaesthesia has seen increased use in contemporary primary total knee arthroplasties (TKAs). However, controversy exists about the benefits of spinal in comparison to general anaesthesia in primary TKAs. This study aimed to investigate the pain control, length of stay (LOS), and complications associated with spinal versus general anaesthesia in primary TKAs from a single, high-volume academic centre. We retrospectively identified 17,690 primary TKAs (13,297 patients) from 2001 to 2016 using our institutional total joint registry, where 52% had general anaesthesia and 48% had spinal anaesthesia. Baseline characteristics were similar between cohorts with a mean age of 68 years (SD 10), 58% female (n = 7,669), and mean BMI of 32 kg/m2 (SD 7). Pain was evaluated using oral morphine equivalents (OMEs) and numerical pain rating scale (NPRS) data. Complications including 30- and 90-day readmissions were studied. Data were analyzed using an inverse probability of treatment weighted model based on propensity score that included many patient and surgical factors. Mean follow-up was seven years (2 to 18).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
Complex fractures of the femur and tibia with associated severe soft tissue injury are often devastating for the individual. The aim of this study was to describe the two-year patient-reported outcomes of patients in a civilian population who sustained a complex fracture of the femur or tibia with a Mangled Extremity Severity Score (MESS) of ≥ 7, whereby the score ranges from 2 (lowest severity) to 11 (highest severity). Patients aged ≥ 16 years with a fractured femur or tibia and a MESS of ≥ 7 were extracted from the Victorian Orthopaedic Trauma Outcomes Registry (January 2007 to December 2018). Cases were grouped into surgical amputation or limb salvage. Descriptive analysis were used to examine return to work rates, three-level EuroQol five-dimension questionnaire (EQ-5D-3L), and Glasgow Outcome Scale-Extended (GOS-E) outcomes at 12 and 24 months post-injury.Aims
Methods
The purpose of this study was to compare outcomes of combined total joint arthroplasty (TJA) (total hip arthroplasty (THA) and total knee arthroplasty (TKA) performed during the same admission) versus bilateral THA, bilateral TKA, single THA, and single TKA. Combined TJAs performed on the same day were compared with those staged within the same admission episode. Data from the National (Nationwide) Inpatient Sample recorded between 2005 and 2014 were used for this retrospective cohort study. Postoperative in-hospital complications, total costs, and discharge destination were reviewed. Logistic and linear regression were used to perform the statistical analyses. p-values less than 0.05 were considered statistically significant.Aims
Patients and Methods
Increasing numbers of posterior lumbar fusions
are being performed. The purpose of this study was to identify trends
in demographics, mortality and major complications in patients undergoing
primary posterior lumbar fusion. We accessed data collected for
the Nationwide Inpatient Sample for each year between 1998 and 2008
and analysed trends in the number of lumbar fusions, mean patient
age, comorbidity burden, length of hospital stay, discharge status,
major peri-operative complications and mortality. An estimated 1 288 496
primary posterior lumbar fusion operations were performed between
1998 and 2008 in the United States. The total number of procedures,
mean patient age and comorbidity burden increased over time. Hospital
length of stay decreased, although the in-hospital mortality (adjusted
and unadjusted for changes in length of hospital stay) remained
stable. However, a significant increase was observed in peri-operative
septic, pulmonary and cardiac complications. Although in-hospital mortality
rates did not change over time in the setting of increases in mean
patient age and comorbidity burden, some major peri-operative complications
increased. These trends highlight the need for appropriate peri-operative services
to optimise outcomes in an increasingly morbid and older population
of patients undergoing lumbar fusion.
