Study Evaluates Impact of Hypogonadism Following TKA

A study published online in The Journal of Arthroplasty found that patients with hypogonadism undergoing total knee arthroplasty (TKA) may be at greater risk for medical complications, revision, longer hospital length of stay (LOS), and increased cost of care. Primary TKA patients were stratified into two groups: those with (n = 1,681) and without (n = 6,712) hypogonadism. Patients with hypogonadism had a greater incidence of 90-day complications compared to patients without (9.45 percent versus 4.67 percent), as well as two-year revisions (3.99 percent versus 2.8 percent, respectively). LOS was longer in the hypogonadism cohort (3.47 days versus 3.27 days), and 90-day costs were higher for hypogonadism patients ($15,564.31 vs. $14,856.69, respectively).

Study Assesses Impact of Outpatient Setting on Shoulder Surgery Outcomes

A study published online in Arthroscopy compared outcomes of shoulder surgery performed in the hospital-based outpatient department (HOPD) versus ambulatory surgical center (ASC). Patients undergoing arthroscopy and related surgeries in the HOPD or ASC settings were included, but arthroplasties were excluded. Outcomes included 90-day unanticipated admission after surgery, readmission, deep vein thrombosis, pulmonary embolism, and wound infection. Final analysis included 84,658 patients: 28,730 ASC and 56,819 HOPD patients. All measured outcomes were significantly greater in the HOPD cohort. The following factors were associated with unplanned admission: increasing Charlson Comorbidity Index score, HOPD service location, general anesthesia, male sex, and open surgery.

Study Assesses Effect of Medial Buttress Plate in Femoral Neck Fractures

The addition of a medial buttress plate for the treatment of distressed femoral neck fractures may improve stability and performance, according to a study published online in Injury. Using a previously designed medial anatomical buttress plate, the researchers conducted finite element analyses comparing a combination treatment using the plate and cannulated screws versus a combination of tubular plate with cannulated screws and cannulated screws alone. Compared to the other two techniques, the use of the medial anatomical buttress plate was associated with greater stability in the femur and stress distributions, stress peaks, and Z axis displacements.

Study Identifies Factors of Posterior Lumbar Spine Fusion Impacted by Obesity

A retrospective study published online in the European Spine Journal observed a negative association between obesity and certain outcomes following open posterior lumbar spine fusion (PLSF). Patients who underwent open PLSF from 2011 to 2018 were stratified into two groups: obese (body mass index ≥ 30 kg/m 2; n = 279) and nonobese (n = 290). Assessments preoperatively and at final follow-up included visual analog scale (VAS) back pain, VAS leg pain, and Oswestry Disability Index. Obese patients were more likely to have diabetes and an American Society of Anesthesiologists Physical Status Classification System score ≥ 3. Compared to nonobese patients, obese patients had longer operative times; however, there were no between-group differences in radiographic measurements, patient-reported outcomes, postoperative complications, or reoperations.

Study: What Factors Influence Distal Radius Fracture Outcomes?

A study published online in The Journal of Hand Surgery identified predictors of better or worse outcomes in distal radius fracture (DRF) patients. Data were gathered from the Wrist and Radius Injury Surgical Trial, a 24-site, randomized study of DRF patients who required surgery. The primary outcome was the Michigan Hand Outcomes Questionnaire (MHQ) summary score one year following treatment. The following factors were most closely associated with MHQ score: pain at enrollment, education, age, and number of comorbidities. Patients with a high school education and severe pain had the lowest MHQ scores, while patients with less pain, higher education, aged ≤ 87 years, and no comorbid conditions had the highest scores.
