Study: One-year Radiographic Outcomes in RTSA with a Short Stem
Reverse total shoulder arthroplasty (RTSA) performed with a short-stem humeral implant led to excellent radiographic outcomes at one year postoperatively, according to a study published in the July 15 issue of the Journal of the AAOS ®. The researchers compared 137 RTSAs with short stems and 139 with standard-length stems. Ninety-five percent of short stems were placed in neutral alignment compared with 89.25 percent of standard stems. There were fewer radiographic changes in the short stem group as well (0.7 percent versus 5.0 percent).
Study: Similar Discharge Time after Same-day TKA with Either Mepivacaine or Ropivacaine
The use of mepivacaine versus ropivacaine for spinal anesthesia during same-day discharge (SDD) total knee arthroplasty (TKA) did not significantly alter discharge times, according to a retrospective study published online in The Journal of Arthroplasty. The study included 35 TKA patients and 172 unicompartmental knee arthroplasty (UKA) patients. Discharge times were similar for both procedures, regardless of use of mepivacaine or ropivacaine.
Study: Risk Factors of Acute Ischemic Stroke after Hip Fracture in Older Patients
Patients aged ≥65 years who had hypertension were more likely to have an acute ischemic stroke (AIS) after hip fractures, according to a study published online in BMC Musculoskeletal Disorders. Of 1,577 patients, 60 had AIS after fracture. The most common comorbidities in patients with AIS were hypertension (73.3 percent), prior stroke (46.7 percent), and diabetes (35.0 percent). Other complications that were common (≥45.0 percent) in patients with post-fracture AIS were hypoproteinemia, electrolyte disorders, anemia, deep vein thrombosis, and pneumonia.
Study Investigates Scaphoid Excision with Arthroscopic Four-corner Arthrodesis Techniques
A study published online in the Journal of Hand Surgery reported satisfactory outcomes with an arthroscopic four-corner arthrodesis technique, using two headless screws, for scaphoid excision. The study included 17 patients with at least one year of follow-up. Patients significantly improved in functional and pain scores, and the average return to work was at 10 weeks. There were no clinically meaningful changes in the flexion-extension arc, although the wrist range of motion increased in the radioulnar plane.
Study: Pain Catastrophizing Is Associated with Worse PROMs in Patients with Plantar Fasciitis or Ankle Instability
A study published online in Foot & Ankle International reported a correlation between Pain Catastrophizing Scale (PCS) scores and other patient-reported outcome measures (PROMs) in patients with plantar fasciitis or chronic ankle instability. Based on scores from 201 patients, higher PCS scores significantly correlated with worse scores in the Visual Analog Scale, Pain Disability Index, 12-item Short Form Survey mental component, and 8-item Somatic Symptom Scale.
Updated CPG Details Hip Fractures in Older Patients
In December 2021, the AAOS Board of Directors approved a complete update to the Clinical Practice Guideline (CPG) on the Management of Hip Fractures in Older Patients. The new guideline revised the 2014 Management of Hip Fractures in the Elderly CPG with changes to 80 percent of previous recommendations. This article features an interview with members of the CPG work group to discuss these updated recommendations.
