AAOS Continues Its Commitment to Safety; Requires Masks at 2021 Annual Meeting

The AAOS 2021 Annual Meeting, Aug. 31 to Sept. 3 in San Diego, is just around the corner, and AAOS is committed to creating a safe and healthy environment for all attendees, exhibitors, San Diego Convention Center workers, AAOS staff, and the community. As such, all attendees will need proof of vaccination or a negative COVID-19 test result from within 72 hours of the first day of attendance in order to enter the convention center. Attendees will also need to properly wear a face covering/mask while in public event spaces. Faculty or designated speakers will be allowed to remove their masks while presenting but should wear masks at all other times. Visit the AAOS 2021 Health & Safety Resources webpage for the latest updates and guidance.

Meta-analysis of RCTs Compares Tissue Adhesives to Standard Wound Care in TJA

A meta-analysis of ten randomized controlled trials (RCTs) found no additional benefits for tissue adhesives (TA) as an adjunct or closure method versus traditional wound closure in total joint arthroplasty (TJA). This study was published online in The Journal of Arthroplasty. Rates of wound infection, discharge, and dehiscence, as well as length of stay and patient satisfaction scores, were comparable between TA and subcuticular sutures (SCS) or skin staples (ST). TA was significantly associated with longer time to closure versus ST, but shorter time to closure compared to SCS.

Study: 2D versus 3D Glenoid Version Measurements prior to TSA

Two-dimensional (2D) glenoid version measurements (via CT scan) were retroverted less often than three-dimensional (3D) measures, according to a study published online in the Journal of Shoulder and Elbow Surgery. Scans from 315 shoulders undergoing total shoulder arthroplasty (TSA) were assessed. Average 2D measurements were significantly less retroverted compared to 3D measurements (–4.9 degrees versus –8.4 degrees). 3D measurements were more retroverted than 2D measurements 73 percent of the time. With outliers excluded, high error samples were evenly distributed throughout the data.

Study: One-week Immobilization is Safe after Nonoperative Humeral Fracture Treatment

A study published in the August 8 issue of the Journal of Bone & Joint Surgery found a short (one-week) immobilization period after nonsurgical management for proximal humeral shaft fractures was safe, with similar outcomes to longer immobilization. The researchers randomized 143 patients to one or three weeks of immobilization. Visual Analog Scale and other functional assessment scores were comparable overall between one week and two years postoperatively. There were no significant differences in complications.

Study: Machine Learning Model Predicts Prolonged Opioid Use after Hip Arthroscopy

A study published online in Arthroscopy assessed a machine learning–based tool to predict likelihood of prolonged opioid use (>90 days) after hip arthroscopy. Six potential algorithms were developed using the Military Data Repository (n = 6,760). Overall, 40.9 percent of patients filled at least one opioid prescription >90 days postoperatively. A model developed using the Artificial Neural Network methodology demonstrated sufficient discrimination and calibration for clinical use. Factors associated with prolonged opioid use were pre- and postoperative opioid use, age, mental health comorbidity, and preoperative substance use disorder.

Study: Interdigital versus Transarticular Lateral Release with Scarf Osteotomy

Interdigital versus medial transarticular approaches for lateral soft-tissue release with scarf osteotomy were both effective for treatment of severe hallux valgus, according to a study published online in Foot & Ankle International. Seventy-seven feet (interdigital, n = 36; transarticular, n = 41) were followed for at least 93 months. American Orthopaedic Foot and Ankle Society scores improved from 60 to 93 and 59 to 95 in the transarticular and interdigital groups, respectively. Hallux valgus and intermetatarsal angles improved in both treatment groups. Clinical and radiographic outcomes were also comparable overall.
