Study Assesses Antibiotic Resistance during Two-stage Revision for PJI

A retrospective study published online in The Journal of Arthroplasty measured the incidence of antibiotic-resistant infection after two-stage revision for chronic culture-positive hip and knee periprosthetic joint infection (PJI). Ten out of 142 total patients (7.04 percent) experienced antibiotic resistance during their two-stage revision. Twenty-five patients (17.6 percent) had positive cultures at prosthetic reimplantation, of whom 16 presented with a novel organism and 9 had recurrent infection. During the two-stage revision, 15 patients (10.56 percent) had persistent infection and 25 (17.6 percent) had novel infection. Twenty-six patients (18.3 percent) had reinfection of the same joint within one year of revision.

Study: Complaints and Outcomes of Shoulder Instability in Young Athletes

A study published online in the Journal of Shoulder and Elbow Surgery evaluated characteristics of shoulder instability among 58 high school and college athletes. Thirty patients had anterior instability and 28 had posterior instability. Injury due to contact event, surgical management rate, outcomes were similar between diagnoses. Patients with anterior instability reported chief complaints of instability (70 percent). Most patients with posterior instability (96 percent) complained of functional interference. Patients treated nonoperatively for anterior instability had higher initial disability compared to nonoperative patients with posterior instability. Post-discharge Penn Shoulder Scores after nonoperative treatment were significantly higher for the anterior versus posterior group (61±18.7 versus 27±25.2).

Study: EOS 2D Imaging Is Effective for Measuring Pedicle Size before Scoliosis Surgery

A study published online in the European Spine Journal assessed the EOS two-dimensional (2D) biplanar low-dose radiograph system for measuring preoperative pedicle size in 16 patients treated for idiopathic scoliosis. Overall, 203 pedicles were analyzed and 2D radiographs were compared with reconstructed intra-operative 3D images. EOS and 3D images showed strong correlations for intra- and extracortical pedicle height and width measurements, though there were some significant but clinically irrelevant differences in all measures except extracortical height. There were no significant differences in intra- and extracortical width among pedicles classified as Nash and Moe 0. Intra- and interobserver reliability was also high.

Study: ROM Preservation after Wrist Denervation for Advanced Wrist OA

A study published online in the Journal of Hand Surgery hypothesized that preserved range of motion (ROM) after wrist denervation for advanced wrist osteoarthritis (OA) would lead to improvements in pain and function. Thirty patients treated after scapholunate advanced collapse arthritis were followed for an average 47 months. Two patients required conversion to wrist fusion. For the remaining patients, total wrist-flexion extension improved by an average of 5 degrees. Mean Patient-Related Wrist Evaluation scores decreased from 82.4 to 60.9 points and mean QuickDASH (Disabilities of the Arm, Shoulder, and Hand) scores decreased from 32.4 to 24.8 postoperatively.

Study: Ankle Syndesmosis Reduction Quality Associated with Functional Scores

A study published online in Injury utilized CT scans to evaluate how ankle syndesmosis reduction quality impacted outcomes in 34 patients treated for ankle fracture. Twenty-six patients (76.5 percent) had anatomical reduction and 8 patients (235 percent) had non-anatomical reduction. Seventeen patients with anatomical reduction (65.4 percent) were male and 18 (66.7 percent) had type B fractures. In patients with non-anatomical reduction, three (37.5 percent) were male and there was similar incidence of type B and C fractures. Anatomical reduction was significantly associated with improved American Orthopedic Foot and Ankle Scores and Visual Analog Scale pain scores.
