Article Synopsis
- Low back pain affects up to 84% of people and is the top cause of disability in the U.S.; sacroiliac joint dysfunction accounts for 10% to 38% of these cases.
- A thorough examination of the sacroiliac joint and nearby areas is essential for diagnosing pain, using multiple provocation tests and imaging techniques for accurate results.
- Treatment options for low back pain range from non-invasive methods like medication and physiotherapy to more invasive procedures, but caution is needed as certain surgeries can lead to further degeneration of the sacroiliac joint and hip.
RATIONALE+OBJECTIVE/ Cystic fibrosis (CF) is characterized by bronchiectasis on imaging, while functionally evolving towards obstructive impairment. Despite its assumed importance in CF, small airway remodeling and its relation to bronchiectasis, is still poorly understood. METHOD/ On high-resolution computed tomography (HRCT, 600µm, CF=21, control=6) and micro-computed tomography (µCT, 150µm, CF=3, control=1) scans of inflated explant lungs, AV% (airway/total lung volume) was calculated as marker for bronchiectasis, while airway segmentation was used for generation analysis.

Identification of increased PT using anteroposterior (AP) pelvic radiographs could avoid additional spinopelvic radiographs. This study aimed to (1) describe which AP pelvic parameters most accurately estimate sagittal PT, and (2) determine thresholds for these parameters that can identify patients with increased PT.

An adequate interpretation of acetabular version and coverage on radiographs is essential to determine the optimal treatment strategy (periacetabular osteotomy vs hip arthroscopic surgery). The crossover sign (COS) has been associated with the presence of acetabular retroversion, and the anterior wall index (AWI) and posterior wall index (PWI) assess anteroposterior acetabular coverage.

Contemporary hip-spine analyses provide information on standing, functional cup orientation. This study aims to (i) characterize cup orientations when supine and standing; (ii) determine orientation differences between postures; and (iii) identify factors associated with magnitude of orientation differences.
