The effect of vitamin D on the speed and quality of pediatric fracture healing.

Purpose: To evaluate the effect of vitamin D on the speed and quality of pediatric fracture healing.

Methods: A 4-year prospective study of healthy children with shaft fractures of the forearm bones (treated with minimally invasive osteosynthesis) or femur (treated by traction or by minimally invasive osteosynthesis). All children had their vitamin D levels examined four times-at the time of the injury, 1, 3, and 5 months after the injury.

Ultrasound imaging in diagnostics of Monteggia lesion in children.

Purpose: The aim of the study is to evaluate the use of ultrasound imaging in diagnostics of Monteggia lesion in children where conventional radiographs and the use of the radiocapitellar line fail to provide an accurate diagnosis.

Methods: Prospective diagnostic study of 70 patients treated between May 2018 and July 2021 in a pediatric level 1 trauma center. In 20 patients with the confirmed radiographic diagnosis of Monteggia lesion, an ultrasound of the humeroradial joint was performed to determine signs of both normal and dislocated elbow joint.

Paediatric pelvic injuries: a retrospective epidemiological study from four level 1 trauma centers.

Aim Of The Study: Epidemiologic evaluation of pelvic ring injuries in children.

Methods: Retrospective analysis over a period of 13 years, excluding pathological fractures. AO/OTA type, epidemiological data, type of treatment, and complications were recorded.

[Advantages and Pitfalls of Stabilisation of Supracondylar Humerus Fractures in Children by Lateral Approach Only].

PURPOSE OF THE STUDY Supracondylar humerus fracture (SCF) with dislocation is indicated for closed reduction and osteosynthesis. The method achieving the best stability is CRCPP (closed reduction and crossed percutaneous pinning), even though there is a risk of iatrogenic ulnar nerve injury. The CRLPP (closed reduction and lateral percutaneous pinning) method eliminates this risk at the cost of less stable osteosynthesis.

Chemical characterization of mountain forest soils: impact of long-term atmospheric deposition loadings (Czech-Polish-German border region).

The composition of lipids in soil offers clues to soil degradation processes due their persistency and selectivity in soil, and close relation to long-term processes in the ecosystem, thanks to their role in cell membranes of organisms. Organic solvent-extractable compounds were recovered from soils collected at two sites differing in the degree of forest damage. Gas chromatography/mass spectroscopy and Fourier transform infrared spectroscopy were applied in order to characterize solvent-extractable lipids.
