Ehlers-Danlos Syndromes Are Associated with Dislocation, Reduced Implant Survival after THA
A study published in the Feb. 15 issue of the Journal of the AAOS ® found that patients with Ehlers-Danlos syndromes (EDS) have higher rates of perioperative dislocation and reduced implant survival after total hip arthroplasty (THA) than patients without EDS. The researchers compared 354 THA patients with EDS with 3,518 matched controls. Ninety-day dislocation rates were 4.2 percent for the EDS group, versus 1.7 percent of controls; EDS was significantly associated with 90-day dislocation. Five-year implant survival was 92.7 percent for patients with EDS and 96.1 percent for controls.

Study: Factors Associated with Success of Chronic Antibiotic Suppression of PJIs
Factors such as gram-negative infections and multiple changes to the antibiotic regimen were associated with failure of chronic antibiotic suppression (CAS) for prosthetic joint infections (PJIs), according to a retrospective study published online in The Journal of Arthroplasty. PJIs in 31 knees and 14 hips were included, with a median follow-up of 50 months. Failure was defined as reoperation or infection-related mortality. The overall success of CAS was 67 percent (n = 30). Hip arthroplasty patients were less likely to require reoperation after CAS than knee arthroplasty patients. Severe antibiotic side effects were rare.

| Study: Lower Velocity, Greater Joint Load during Throwing in Baseball Players with Early Trunk Rotation
Early trunk rotation (ETR) during throwing in elite baseball players was associated with lower ball velocity and higher shoulder joint loading compared with non-ETR throwers, according to a study published online in the Journal of Shoulder and Elbow Surgery. Fifty-seven athletes were divided according to ETR status. Ball velocity was 120 km/h in the ETR group and 127 km/h in non-ETR athletes. Shoulders of throwers with ETR demonstrated horizontal adduction lag and dropped elbow, the authors noted. ETR shoulders also had increased maximal posterior force, inferior force, horizontal abduction moment, and vertical adduction moment compared with non-ETR shoulders.

| Study: History of Opioid Misuse Is Associated with Greater Resource Utilization after Spinal Fusion
A retrospective study published in Current Orthopaedic Practice found that a history of opioid misuse or abuse (OMA) prior to thoracolumbar spinal fusion was associated with increased postoperative resource utilization. The researchers assessed data on 73,442 spinal fusion patients, including 1,332 patients with a history of OMA. Prior OMA was associated with a longer length of stay (4.5 days versus 3.8 days), higher healthcare costs ($129,264 versus $118,065), and greater odds of readmission within one year, including a greater incidence of hospitalization for OMA-specific issues (16.3 percent versus 0.8 percent), compared with patients without a history of OMA.
