Background: A larger joint line convergence angle (JLCA) increases the stress load on the medial compartment. Few reports, however, have discussed the effect of the JLCA on the cartilage status and clinical outcomes after opening-wedge high tibial osteotomy (OWHTO).
Purpose/hypothesis: To reveal the effect of the JLCA on clinical results after OWHTO.
In this paper, we introduce a new method for precise determination of the calibration function of liquid crystal spatial light modulators (LC-SLMs). The proposed method shares the advantages of commonly used methods, interferometric and diffraction-based methods, and is free of their disadvantages. The method proposed here is based on the evaluation of Fresnel diffraction of light from a phase-discontinuity pattern loaded into the SLM device.

Another observed complication of a hinge fracture is an unintentional change of the postoperative femoral torsion of up to + 9.5° in conventionally performed DFO.

Background/purpose: Although clinical studies have suggested a link between non-axial forces and reduced longevity of cervical restorations, the underlying mechanisms require further numerical investigation. This in-silico study employed a cohesive zone model (CZM) to investigate interfacial damage in a cervical restoration subjected to different load directions.
Materials And Methods: A plane strain model of a maxillary premolar was established, with a wedge-shaped buccal cervical restoration.
Interstitial lung disease (ILD) can lead to pulmonary hypertension (ILD-PH), worsening prognosis and increasing mortality. Diagnosing ILD-PH is challenging due to the limitations of imaging methods. Right heart catheterization (RHC) is the gold standard for diagnosing PH but is limited to ILD patients considered for lung transplantation.
