Objectives: This study investigates the regional variation in areal bone mineral density (aBMD) at the distal radius, a critical site for osteoporosis-related fractures. Understanding aBMD distribution is essential for accurate diagnosis and management of osteoporosis.
Methods: The study involved 261 participants aged over 50. Using dual-energy X-ray absorptiometry (DXA) scans, aBMD was recorded across contiguous regions of the distal radius. Factors considered include age, sex, and hand dominance, providing a comprehensive view of aBMD distribution.
Results: The findings indicated a consistent pattern in aBMD distribution along the radius, with a plateau around the one-third distance from the wrist. Notably, significant differences in aBMD were observed between age groups, especially among post-menopausal women. The study also recorded minor variations in aBMD between dominant and non-dominant forearms.
Conclusions: The study's insights into aBMD variation at the distal radius have implications for osteoporosis research and clinical diagnosis. It highlights the importance of standardized region of interest placement in DXA scans for accurate assessment.

Case: A 41-year old man fell from height sustaining displaced radial shaft and ulnar styloid fractures underwent open reduction internal fixation of the radius with early recognition of a radiocapitellar dislocation and longitudinal forearm instability in the early postoperative period. Revision surgery was performed 13 days postoperatively involving annular ligament reconstruction, elbow spanning external fixation, and distal radioulnar joint stabilization. Favorable functional and radiographic outcomes are shown at 1-year follow-up.

We report a series of 12 patients who developed early distal radioulnar joint subluxation after a distal radial fracture, not present on the initial radiographs. Early identification and management of this condition can give good clinical results. IV.

Treatment of distal radial fractures that include small anterior rim fragments can be difficult. We retrospectively reviewed 19 patients in whom an anterior rim plate with locking screws was used. After a median follow-up of 18 months (range 6-32; interquartile range (IQR) 14, 26), the median wrist flexion and extension arc was 70° (range 50-80; IQR 60, 70), the median grip strength was 80% of the contralateral side (range 52-104; IQR 77, 88), the median visual analogue scale score for pain was 0 (range 0-5; IQR 0, 1), the median disabilities of the arm, shoulder and hand score was 2 (range 0-59; IQR 0, 11) and the median modified Mayo wrist score was 80 (range 35-100; IQR 75, 85).

The main objectives of this work are to validate a 1D-0D unsteady solver with a distributed stenosis model for the patient-specific estimation of resting haemodynamic indices and to assess the sensitivity of instantaneous wave-free ratio (iFR) predictions to uncertainties in input parameters. We considered 52 patients with stable coronary artery disease, for which 81 invasive iFR measurements were available. We validated the performance of our solver compared to 3D steady-state and transient results and invasive measurements.

Background: Unstable diametaphyseal radius fractures (DMRFs) can be prone to complications, and treatment strategies are heterogeneous. Studies are difficult to interpret as definitions of the diametaphyseal junction zone (DMJZ) are impractical for clinical use, imprecise, or prone to error.
Methods: We introduce the forearm fracture index (FFI) to define DMRFs in radiographs and ultrasound.
