Study Evaluates Outcomes of Arthroscopic Anatomic Glenoid Reconstruction Using Distal Tibial Allograft

A study published online in The American Journal of Sports Medicine observed good outcomes in patients who underwent arthroscopic anatomic glenoid reconstruction using distal tibial allograft for recurrent anterior shoulder instability. Seventy-three patients (mean age, 28.8 years; 21 patients were female) were treated by the same surgeon. Mean follow-up was 4.7 years. Mean Western Ontario Shoulder Instability Index score decreased from 71.1 preoperatively to 25.6 postoperatively. No dislocation recurrences or nerve injuries were observed Subluxation symptoms presented in one patient. Five patients sustained hardware complications necessitating screw removal. Among 66 patients with available postoperative CT scans, the graft union rate was 100 percent.

Study: Which Oncology Patients Are at Risk of SSI?

A retrospective study published in the Oct. 15 issue of the Journal of the AAOS ® identified predictors of surgical site infection (SSI) in orthopaedic oncology patients. Over a six-year period, 757 procedures were performed on 624 patients who were preoperatively diagnosed with a malignant or possibly malignant neoplasm of the bone or soft tissues. Significant patient-specific SSI risk factors were malignancy, smoking history, and American Society of Anesthesiologists (ASA) score. In controlled analyses, the two factors independently significantly associated with SSI risk were whether the surgery was done on an inpatient basis and the number of previous surgeries performed on the same site.

Study Compares Altmetric Attention Scores and Social Media Attention for Orthopaedic Versus Nonorthopaedic RCTs

A study published online in Arthroscopy compared the Altmetric Attention Score (AAS) and citation rates between orthopaedic versus nonorthopaedic randomized, controlled trials (RCTs) and assessed factors that increased their social media exposure. Orthopaedic (n = 9) and nonorthopaedic (n = 59) RCTs published between January 2011 and December 2016 in The New England Journal of Medicine, The Lancet, JAMA, Annals of Internal Medicine, and Archives of Internal Medicine were included. Orthopaedic studies had a significantly higher mean AAS than nonorthopaedic studies (574.0 versus 256.9). Orthopaedic studies were more likely to be mentioned on Twitter and Facebook. Higher AAS was associated with more citations for orthopaedic RCTs.

Study Compares Adjacent Segment Disease Requiring Surgery After Cervical Total Disk Replacement Versus Anterior Cervical Diskectomy and Fusion

A meta-analysis published online in the Journal of Orthopaedic Surgery and Research compared symptomatic adjacent-level disease requiring surgery following cervical disk replacement versus anterior cervical fusion. RCTs with more than 48 months of follow-up were included. At 48 to 120 months of follow-up, cervical disk replacement patients had a significantly lower overall rate of symptomatic adjacent-level disease requiring surgery. When using unrestricted prosthesis, the cervical disk replacement group had a significantly lower disease rate, but when assessing the cervical disk replacement group using semi-restricted prosthesis, the difference was not statistically different from the fusion group.

Study: Antegrade Intramedullary Compression Screw Fixation of Metacarpal Fractures

A study published online in The Journal of Hand Surgery reported intramedullary screw sizes for each metacarpal of the hand to attain interference fit with fracture fixation. One hundred hand radiographs were evaluated. The medullary canal width was narrowest in the ring finger metacarpal in the coronal (2.8 mm) and sagittal planes (3.5 mm). Excluding the thumb, the widest midshaft medullary width was found in the little finger metacarpal in the coronal plane (4.1 mm) and in the middle metacarpal in the sagittal plane (3.9 mm). Maximal dorsal and ulnar overhang was observed at the base of the middle and small metacarpal, respectively.

Study Indicates Pediatric Trauma Patients Do Not Benefit from Longer Fasting

A study that examined the outcomes associated with three different fasting scenarios in patients treated at a level 1 pediatric emergency department (PED) for orthopaedic injuries found that when ASA fasting guidelines for children requiring sedation were followed, length of stay in the PED was significantly longer. The study, presented at the 2020 virtual Annual Meeting of the Pediatric Orthopaedic Society of North America by Derek M. Kelly, MD, FAAOS, also found that adverse events related to sedation are rare and not related to how fasting guidelines are followed. The study was designated as one of the top clinical papers at the meeting.

AAOS Launches New Program Providing Leadership Education, Mentoring, and Network Opportunities

The AAOS Leadership Institute (ALI) is offered in four successive tiers that align to the member’s current level of involvement in the Academy’s governance structure. An essential goal of the ALI program is to extend AAOS leadership opportunities to any interested member, including resident and candidate members, and will serve as a clear pathway and pipeline for those interested in reaching higher levels of Academy leadership. For members already in positions of AAOS leadership, ALI is a good refresher for AAOS strategy, goals, leadership skills, and more. Levels 1 and 2 are available through your Learning Management System (LMS) Dashboard.
