Introduction: The aim of this prospective, multicentre study was to evaluate the influence of local bone mineral density (BMD) on the rate of mechanical failure after locking plate fixation of closed distal radius fractures.
Materials And Methods: Between June 2007 and April 2010, 230 women and 19 men with a mean age of 67 years were enrolled. Dual energy X-ray absorptiometry measurements for BMD of the contralateral distal radius were made at 6 weeks post-surgery. Follow-up evaluations at 6 weeks, 3 months and 1 year included wrist mobility and strength as well as standard radiographs. Any local bone/fracture or implant/surgery-related complications were documented. The Disability of the Arm, Shoulder, and Hand (DASH), Patient Rated Wrist Evaluation (PRWE), and EuroQol-5D scores were also recorded at the nominated time points.
Results: Nine patients were reported with mechanical failure at an estimated risk of 3.6 %. The BMD measurements were generally low for the study population with no difference between patients with (0.561 g/cm(2)) and without (0.626 g/cm(2)) mechanical failure (p = 0.148). None of the patients achieved their pre-injury functional level and quality of life status after 1 year. 1-year DASH and PRWE scores as well as the difference in maximum grip strength of the affected wrist relative to the contralateral side were significantly higher for patients with mechanical failure (p ≤ 0.036).
Conclusions: Our study could not identify a clear association between bone mineral density status and the risk of mechanical failure. Although the risk for mechanical failure after treatment of distal radius fractures with palmar locking plates is low, these complications must be avoided to prevent negative impact on long-term patient functional and quality of life outcome.

Background: Unrestricted kinematic alignment (uKA) in total knee arthroplasty (TKA) has the theoretical advantage of reproducing patients' constitutional alignment and restoring the pre-arthritic joint line position and obliquity. However, modifications of the original uKA technique have been proposed due to the potential risk of mechanical failure and instability. Given the significant variability in soft tissue behavior within the same bony morphology group, uKA pure knee resurfacing could be occasionally detrimental.

Background: Hypoxic hepatitis (HH) is commonly seen in critically ill patients, such as those with cardiac shock, sepsis, and respiratory failure. However, data are limited regarding its impact on the prognosis of patients with cardiac arrest (CA).
Methods: We conducted a systematic review and meta-analysis of studies from PubMed, EMBASE, and the Cochrane Library from inception to July 30, 2024.

Background And Objective: Microsurgical resection of tumor is an important treatment for children with fourth ventricular tumors. There is a lack of data describing risk factors for postoperative extubation failure (EF) in these children. We aimed to identify risk factors for EF in children with fourth ventricular tumors and to determine the association between EF and clinical outcomes.

The slope of open-pit mines is typically characterized by an interaction structure involving multiple weak layers, with these structural characteristics serving as key factors in determining rock slope stability. Under the influence of random factors such as engineering activities and geological structures, the weak layers of the slope and the intact rock layers undergo relative changes. This interaction leads to a more pronounced spatial variability in the geotechnical parameters that inherently exist.

The application of flexible risers has led to increased production of fluid contents in the marine industry. This paper presents the design challenges of a flexible riser subjected to internal pressure under deep-water conditions, at a water depth of 2000 m. Parametric variations with extensive dynamic analysis were carried out.
