Rank-Ordered List of Cost-effective Strategies for Preventing Prosthetic Joint Infection in Total Joint Arthroplasty in an Academic US Hospital.

Although the overall rate of prosthetic joint infection (PJI) is low, it remains a major complication associated with total joint arthroplasty (TJA). PJI represents a significant economic burden to the health care system that is projected to increase commensurate with increasing joint replacement volumes. This review provides a rank-ordered list of cost-effective strategies that are performable intraoperatively and have data supporting their efficacy at preventing PJI after TJA.

Outcome of the Wagner Cone femoral component for difficult anatomical conditions during total hip arthroplasty.

Purpose: Total hip arthroplasty (THA) in patients with small or unusual proximal femoral anatomy is challenging due to sizing issues, control of version, and implant fixation. The Wagner Cone is a monoblock, fluted, tapered stem with successful outcomes for these patients; however, there is limited information on subsidence, a common finding with cementless stems.

Methods: We retrospectively reviewed our cases using the modified Wagner Cone (Zimmer, Warsaw, IN) implanted over a 13-year period (2006-2019) in patients with small or abnormal proximal femoral anatomy.

Safety and Effectiveness of Outpatient Total Ankle Arthroplasty.

Background: Total ankle arthroplasty (TAA) is a surgical procedure commonly reserved for patients suffering from symptomatic end-stage ankle arthritis. As the number of TAAs increases, so does the associated economic burden. Given these economic constraints, there has been interest in the feasibility of outpatient TAA.

Cost-effectiveness of dual-mobility components in patients with displaced femoral neck fractures.

Aims: Total hip arthroplasty (THA) with dual-mobility components (DM-THA) has been shown to decrease the risk of dislocation in the setting of a displaced neck of femur fracture compared to conventional single-bearing THA (SB-THA). This study assesses if the clinical benefit of a reduced dislocation rate can justify the incremental cost increase of DM-THA compared to SB-THA.

Methods: Costs and benefits were established for patients aged 75 to 79 years over a five-year time period in the base case from the Canadian Health Payer's perspective.

Treatment of Geriatric Acetabular Fractures-A Concise Review of the Literature.

Optimal management of acetabular fractures (AF) in the elderly has not been defined clearly. The incidence of such fractures is rising in the aging population. Advancements in implant technology have improved the longevity of combined or staggered total hip arthroplasty procedures for this patient population, thus allowing earlier weight bearing and continued functional independence.

Converting hip and knee arthroplasty cases to same-day surgery due to COVID-19.

Aims: In 2020, the COVID-19 pandemic meant that proceeding with elective surgery was restricted to minimize exposure on wards. In order to maintain throughput of elective cases, our hospital (St Michaels Hospital, Toronto, Canada) was forced to convert as many cases as possible to same-day procedures rather than overnight admission. In this retrospective analysis, we review the cases performed as same-day arthroplasty surgeries compared to the same period in the previous 12 months.

Impact of 3D Printed Calcaneal Models on Fracture Understanding and Confidence in Orthopedic Surgery Residents.

Objective: To determine if three-dimensionally printed (3Dp) fracture models can improve orthopedic trainee education.

Design: A prospective comparison study of orthopedic trainees and attending surgeons was performed, where a range of calcaneal fractures were used for creating anonymized 3Dp models. Study participants rotated through workstations viewing computed tomography images and either a digital 3D volume rendering or 3Dp model of the fractured calcaneus.

Surgical outcomes of chronic isolated scapholunate interosseous ligament injuries: a systematic review of 805 wrists.

Background: Management of chronic isolated scapholunate interosseous ligament (SLIL) injuries has generated a substantial volume of low-quality literature with descriptions of multiple new surgical techniques, and the impact of instability pattern and the optimal surgical technique remain unclear. The primary goal of this review was to compare clinical, radiographic and patient-rated outcomes between current surgical techniques.

Methods: We performed a systematic literature search using multiple databases.

Necrotizing Fasciitis Involving Spine: Unusual Medical Emergency for Spine Surgeon.

Background: Necrotizing fasciitis (NF) is a surgical diagnosis characterized by a rapidly progressive soft tissue infection, widespread tissue necrosis, and associated systemic illness. Friability of the superficial fascia, dishwater-gray exudate, and absence of pus are surgical characteristics of this diagnosis. Due to rapid progression of the infection, early recognition and aggressive surgical debridement are crucial to reduce mortality.

Kinematic differences between gender specific and traditional knee implants.

In the ongoing debate about gender-specific (GS) vs. traditional knee implants, there is limited information about patella-specific outcomes. GS femoral component features should provide better patellar tracking, but techniques have not existed previously to test this accurately.
