Exposure to air pollution might decrease bone mineral density and increase the prevalence of osteoporosis: a Mendelian randomization study.

Unlabelled: This study, using Mendelian randomization, reveals a causal link between nitrogen oxides and PM2.5 exposure and reduced total-body bone mineral density, highlighting a potential risk factor for osteoporosis. The findings emphasize the importance of targeted interventions in populations exposed to higher air pollution.

Fusion rates for odontoid fractures after treatment by anterior odontoid screw versus posterior C1-C2 arthrodesis: a meta-analysis.

Objective: For odontoid fractures, surgical treatment approaches including anterior odontoid screw fixation approach and the posterior C1-C2 arthrodesis approach are generally adopted in practice. However, the choice of different surgical procedures remains controversial. In addition to surgical technique, the fusion rate is an important factor contributing to the clinical efficacy.

Angle Stable Interlocking Intramedullary Nails for Tibial Plateau Fractures.

Objective: Angle stable interlocking intramedullary nail (ASIN), a novel technique, has rarely been used for treatment of tibial plateau fractures (TPF). This retrospective study was designed to introduce this novel technique, ASIN, as well as to describe the initial experience and verify the effectiveness when ASIN was used for the management for TPF.

Methods: A cohort of 19 cases with closed TPF aged from 18-70 years with at least 23 months follow-up from November 2008 to September 2013 was analyzed retrospectively.

[POSTEROLATERAL AND POSTEROMEDIAL APPROACHES FOR TREATMENT OF POSTERIOR Pilon FRACTURES IN ELDERLY PATIENTS].

Objective: To explore the clinical outcomes of open reduction and internal fixation by posterolateral and posteromedial approaches for treating posterior Pilon fractures in elderly patients.

Methods: Between August 2009 and August 2014, 20 elderly patients with posterior Pilon fractures were treated with open reduction and internal fixation by posterolateral and posteromedial approaches. There were 14 males and 6 females, aged from 66 to 83 years (mean, 72.

[A probe to the treatment of Madelung deformity].

Objective: To explore a method of treating Madelung deformity.

Methods: Seven cases of Madelung deformity had been treated with the excision of ulnar carpi ulnaris segment and distal osteotomy of radius and tight constrict of extensor carpi ulnaris from Mar. 2000 to Nov.
