Study: Antibiotics with Gram-negative Agent for Managing Early PJI after TKA
According to a retrospective study published online in The Journal of Arthroplasty, for prosthetic joint infection (PJI) following total knee arthroplasty (TKA), vancomycin with gram-negative agents should be considered for Tsukayama Classification and Auckland Classification class A infections. Cephazolin or flucloxacillin should be considered for class C infections, and antibiotics should be withheld until cultures and sensitives are known for class B. Overall, 232 culture positive PJIs were assessed. Early PJIs were notably more resistant and polymicrobial, while gram-negative case distribution was higher in early class A infections compared with late class C. Vancomycin with gram-negative agents provided >90 percent coverage in both classification systems.

| Study: U-shaped Staples or Screws for Ankle Valgus Deformity in Children with Congenital Tibial Pseudarthrosis
According to a retrospective study published in the May/June issue of the Journal of Pediatric Orthopaedics, temporary hemiepiphysiodesis with U-shaped staples or screws is an effective treatment for postoperative ankle valgus deformity in children with congenital pseudarthrosis of the tibia. Of 41 patients, 23 were treated with U-shaped staples, 10 were treated with hollow screws, and eight were treated with cortical bone screws. At a minimum of 12 months follow-up, following internal fixation removal, correction rates were similar between all three groups.

| Study: Indications and Risk Factors for Postoperative Orthopaedic Medical Emergency Team Use
Older age, emergency surgery, higher Charlson Comorbidity Index scores, preoperative delirium or dementia, and nonneck femoral fracture were associated with a higher risk of nonhypotension postoperative orthopaedic medical emergency team (MET) use, according to a retrospective study published in the March/April issue of Current Orthopaedic Practice. Postoperative orthopaedic MET calls between October 2017 and April 2019 were categorized based on triggers and pre-, intra-, and postoperative parameters. Nonhypotension MET calls were more likely to be discharged to high-level care and less likely to have an intensive care unit admission.

| Study: Digital Tomosynthesis for Identifying Pedicle Screw Loosening after Posterior Spinal Fusion
Digital tomosynthesis offers a more accurate and quantitative diagnosis of pedicle screw (PS) loosening compared with conventional methods, according to a study published online in BMC Musculoskeletal Disorders. A total of 41 patients who underwent posterior spinal fusion using PS were evaluated. Based on CT imaging, PS loosening was identified in 12 screws and 60 screws did not have loosening. All patients underwent digital tomosynthesis in standing and lying positions. According to the results, PS loosening was associated with significantly greater displacement angles compared with patients without loosening (5.7 degrees versus 0.6 degrees, respectively).

OVT Review: Direct Anterior Approach for Hip Hemiarthroplasty
Neil Sheth, MD, FAAOS, FACS, reviews a video from the AAOS Orthopaedic Video Theater (OVT) demonstrating techniques, pearls, and pitfalls of the direct anterior approach for hip hemiarthroplasty. “Although the direct anterior approach is routinely performed in the primary, elective total hip arthroplasty setting, a few technical principles are critical when utilizing this approach for a hip hemiarthroplasty,” writes Dr. Sheth.

Virtual Course: AAOS and OTA Present Daily Dilemmas in Trauma
On Saturday, May 14, AAOS and the Orthopaedic Trauma Association (OTA) will cosponsor a virtual course on updates in trauma, led by Paul Tornetta III, MD, FAAOS, and J. Tracy Watson, MD, FAAOS. This case-based course features leaders in trauma presenting their insights on fracture fixation—both operative and nonoperative—as well as complication management, outcomes, and more. The interactive live course is comprised primarily of small group case reviews and faculty panel discussions. This virtual package also includes more than 40 prerecorded lectures and access to all content for 90 days.
