Introduction: Although distal radius fractures (DRFs) are the most common fractures of the human body, there are still ongoing debates concerning the treatment for type A fractures, especially in elderly patients. In spite of good clinical outcomes, it remains unclear whether elderly patients, especially, could regain the preoperative functional level of the wrist. Therefore, we have quantified wrist function within a retrospective study design using patient-reported outcome measures (PROM) and we have analyzed the influence of age between control and patient collective and young vs.

Article Synopsis
  • Researchers studied how well people recover from a specific type of wrist fracture (distal radius fracture) after surgery, looking at differences between men and women as well as age.
  • The study involved 197 patients, mostly older women, and compared their recovery to 110 healthy volunteers using a special survey.
  • Results showed both men and women with the fracture had a worse recovery compared to healthy people, even though the men were younger; nonetheless, both groups could get back to their pre-injury levels with treatment.

Introduction: Although distal radius fractures (DRFs) are the most common fractures of the human body, the best treatment for every fracture type is still debatable. However, randomized controlled trials are difficult to perform. The quality of care can be determined primarily in the context of health care research using register studies.

Out-of-time-order correlators (OTOCs) have been proposed as sensitive probes for chaos in interacting quantum systems. They exhibit a characteristic classical exponential growth, but saturate beyond the so-called scrambling or Ehrenfest time τ_{E} in the quantum correlated regime. Here we present a path-integral approach for the entire time evolution of OTOCs for bosonic N-particle systems.
