RESUMO
BACKGROUND: The Affordable Care Act's Readmission Reduction Program (RRP) and ongoing transparency efforts to promote consumer-driven competition place significant institutional focus on improving 30-day readmission rates. It remains unclear whether the reduction in readmission rates subsequent to the RRP occurred due to improved quality and/or partly due to increased use of observation status in conditions that may have been classified as readmissions prior to the RRP. We hypothesize that a significant percentage of our institution's 30-day readmissions after elective total knee and hip arthroplasty (TKA/THA) overestimate the needs, duration, and complexity of the hospital-based intervention and inaccurately reflect the quality of service provided. METHODS: We performed a retrospective review of prospectively collected quality control data for 30-day returns to hospital after elective TKA/THA at our institution over a 2-year period. After stratification of the readmissions to under 48-hour and over 48-hour length of stay, we calculated the financial implications to our institution if the under 48-hour length of stay admissions were reclassified as an observation by applying discharge-weighted and payment-weighted analyses to the 2017 RRP report. We then calculated the out-of-pocket expenses for the under 48-hour Medicare subpopulation. RESULTS: We found that 16.7% of the 30-day readmissions after elective TKA/THA required a length of stay under 48 hours. If the short length of stay TKA/THA readmissions were reclassified as observations, our institution's 2018 RRP penalty would have been reduced to 39% or $334,512.28. However, this reclassification would result in an increase in out-of-pocket expenses by $540.25 (range $291.56-$1105.08) per patient. CONCLUSION: A subpopulation of 30-day readmissions does not require a level of care consistent with inpatient admission services. Classification of this short length of stay subpopulation as an observation vs an admission per Centers for Medicare and Medicaid Services guidelines would have removed our institution from the TKA/THA-specific RRP penalty. However, this would result in the unintended consequence of shifting costs, particularly self-administered drug costs, to patients.

Background: When performing a total hip arthroplasty via the direct anterior approach (DAA), many orthopedic surgeons utilize an orthopedic traction table. This technique requires an expensive table, time for positioning, staff to operate the table, and time-consuming transitions when preparing the femur. Some surgeons advocate for an "off-table" technique to avoid these difficulties. In this paper, we compare operating room efficiency between on-table and off-table techniques. Material and methods: We retrospectively reviewed patients undergoing total hip arthroplasty by a single surgeon across the transition from on-table to off-table DAA technique. Three cohorts were defined; the last 40 on-table hips, the first 40 off-table hips, followed by the second 40 hips. Timestamps from the operative record were recorded to calculate setup, surgical, takedown, and total room time. Implant fixation, patient demographic data, comorbidities, and complications were recorded. Results: From cohort 1 to 2, there was a 7-minute (14.44%, P = .0002) improvement in setup time but no change in total room time. From cohort 2 to 3, there was an additional 7-minute (15.47%, P < .0001) improvement in setup time, 32-minute (25.88%, P < .0001) improvement in surgical time, and 40-minute (21.96%, P < .0001) improvement in total room time yielding cumulative changes from cohort 1 to 3 of 15 minutes (27.68%, P < .0001), 28 minutes (23.11%, P < .0001), and 43 minutes (23.37%, P < .0001), respectively. There was no correlation between height, weight, or body mass index and time at any interval. Conclusion: Conversion to an off-table DAA technique offers an improvement in operating room efficiency. This is seen in setup, operative, and total room time. Implementation could allow for an additional case each day.
RESUMO
BACKGROUND: Varus malposition is a risk of early failure in total hip arthroplasty. The degree to which the tip of the greater trochanter (GT) overhangs the canal can increase this risk. Although we know proximal femoral anatomy is variable, no study has addressed variations in medial overhang of the GT on plain radiographs. METHODS: All low anteroposterior pelvis radiographs more than 1 year were reviewed 3 times by 2 orthopaedic surgeons and one radiologist. The canal width (CW) was measured 10 cm below the lesser trochanter. Canal overhang (CO) was defined by the distance between the lateral medullary canal and a parallel line beginning at the most medial aspect of the GT. The overhang index (OI) is defined as the percentage of the canal overhung by the GT. RESULTS: The mean CW was 13.5 mm, mean CO 16.4 mm, and mean OI 1.22. Hips were then classified as the following: (A) OI < 0.5 (n = 8), (B) OI 0.5-1.0 (n = 78), (C) OI 1.0-1.5 (n = 191), and (D) OI > 1.5 (n = 68). Intraobserver reliability was excellent for all measures: 0.89 (confidence interval: 0.87-0.91) for CW, 0.96 (0.95-0.97) for CO, and 0.97 (0.97-0.98) for OI. Interobserver reliability was good for CW 0.75 (0.70-0.79) and excellent for CO 0.90 (0.88-0.92) and OI 0.95 (0.94-0.96). CONCLUSIONS: Variations in the morphology of the proximal femur can predispose to varus component malposition. The degree to which the GT overhangs the canal can be quantified and classified based on plain films. This can aid in preoperative planning and help guide intraoperative proximal femoral preparation.
RESUMO
The incidence of periprosthetic fractures have been increasing, and in patients with osteopenic bone, high body mass index, or a combination both, they are difficult to treat and pose a high risk for malunion. Previous studies have compared the use of locking plates and intramedullary nails, and have found that each has its own strengthens and drawbacks, but neither is superior in terms of treating periprosthetic fractures. Here, we present the technique and series of patients treated with a combination of a retrograde intramedullary nail and flare-to-flare lateral locking plate without the use of allograft or autograft supplementation.

Massive allograft can be a useful option in revision total joint arthroplasty for treatment of significant bone loss. In rare cases, revision hip and knee arthroplasty procedures can be performed simultaneously using massive allograft-prosthetic composites. We present an 18 year follow up of a patient who received a simultaneous revision hip and knee total femoral allograft and discuss recent literature as it relates to this case.
RESUMO
OBJECTIVES: The primary purpose of this study is to determine whether a strategy of bringing patients back to the operating room for successive debridements allows for the eventual delayed primary closure (DPC) of fasciotomy wounds. DESIGN: Retrospective cohort study. Data were collected from medical records and radiographs. SETTING: Two urban level 1 trauma centers. PATIENTS: One hundred four adult patients with acute compartment syndrome in the setting of a tibia fracture (open or closed). INTERVENTION: All patients underwent decompressive fasciotomies with closure by either DPC or split-thickness skin grafting (STSG) during a subsequent surgical procedure. MAIN OUTCOME MEASURE: Number of fasciotomy wounds closed by DPC after the initial fasciotomy procedure. RESULTS: Of the 104 patients brought to the operating room for their first debridement after their fasciotomies, 19 patients (18%) were treated with DPC, whereas 42 patients (40%) were closed with STSG because they were believed to be too swollen to allow for primary closure by the treating surgeon. Three of the remaining 43 patients were treated with DPC during their second debridement. No patients who underwent more than 2 washouts could be treated with DPC. No patients who sustained open fractures were able to be closed by DPC (P = 0.02). Patients who underwent STSG on their first postfasciotomy procedure had a significantly shorter hospital stay than patients who underwent additional procedures before closure (12.2 vs. 17.4 days; P = 0.005). CONCLUSIONS: Fasciotomy wounds that are not able to be primarily closed during their first postfasciotomy surgical procedure are rarely closed through DPC techniques. Early skin grafting of these wounds should be considered, especially in the clinical setting of an open injury, because it significantly decreases the length of hospital stay. Other techniques that avoid repeated debridements and attempted closures might also help reduce hospital stay. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

The elderly constitute the most rapidly growing subpopulation in the United States. This age group represents a significant burden on the healthcare system due, in part, to increases in morbidity and mortality associated with an increase in the incidence of intestinal infectious diseases. Our previous studies suggest that impaired homing of IgA immunoblasts from the Peyer's patches to the intestinal lamina propria contributes to the diminished intestinal immune response in the elderly. The present study employs flow cytometry and quantitative immunohistochemistry to assess age-related changes in the numbers of peripheral blood mononuclear cells expressing the homing integrin alpha4beta7 and vascular endothelial cells in the intestine expressing its specific receptor, the address in MAdCAM-1, in inbred Fischer 344 rats. The proportion of alpha4beta7-positive mononuclear cells in young rats is significantly greater than that measured in the blood of senescent animals. Although the density of intestinal lamina propria blood vessels with MAdCAM-1-positive endothelium was greater in young adult rats in comparison to old animals, this difference achieved only borderline statistical significance. This is the first study to examine the expression of these two critical lymphocyte homing molecules as a function of age.
