Multicenter Study
Patient-reported disability in the general Japanese population was associated with medical care visits for low back pain, regardless of pain intensity.
Race/ethnicity is known to affect pain severity and the emotional aspects of pain, with medical care visits also reported to differ according to race/ethnicity. It has been hypothesized that there is an interactive relationship between pain intensity and patient-reported disability and that the interactive relationships are related to medical care visits. However, it remains unclear whether the association between patient-reported disability and medical care visits for low back pain (LBP) are dependent on the pain intensity. The aims of this study were to examine the prevalence of medical care visits among members of the Japanese general population and to analyze the association between patient-reported disability and medical care visits for LBP patients, regardless of the pain intensity. ⋯ Patient-reported disability was associated with medical care visits for LBP, regardless of the pain intensity, with the results similar to those obtained for other races/ethnicities.

Traditional treatments for stiff knees, such as quadriceps snip and V-Y quadricepsplasty, require extensive soft tissue exposure and lead to recurrent poor arc of motion and a permanent extensor lag. In this study, we evaluated the effect of the quadriceps tendon pie-crusting release for treating limited knee flexion in total knee arthroplasty (TKA) and compared the outcomes of two surgical approaches. ⋯ The quadriceps tendon pie-crusting release technique was an effective procedure for improving knee flexion in cases of stiff knee. The midvastus approach maintained the integrity of the extensor mechanism and resulted in better outcomes than the parapatellar approach.

The clinical relevance of D-dimer levels when screening for venous thromboembolism (VTE) in elderly patients with a hip fracture has been reported but has not been fully investigated in patients with fractures caused by high-energy injuries. The purpose of this study was to evaluate the usefulness and limitations of D-dimer in such patients. ⋯ D-dimer can be used as a VTE screening tool in patients with fractures caused by high-energy injuries. Our results suggested that D-dimer analysis to predict VTE was useful in patients with a pelvic fracture or multiple fractures. Our results also suggested that it was less useful for predicting VTE in patients with an isolated lower extremity fracture.
