Medial Protrusio Technique Versus Structural Autologous Bone-Grafting Technique in Total Hip Arthroplasty for Crowe Type II to III Hip Dysplasia.

Background: It is unclear whether acetabular reconstruction techniques have any impact on clinical outcomes. This study aimed to determine (1) whether acetabular reconstruction techniques influenced the position of the acetabular cup and (2) whether clinical outcomes based on the acetabular reconstruction techniques differ in patients undergoing total hip arthroplasty (THA) with Crowe II to III developmental dysplasia of the hip.

Methods: This was a retrospective analysis of prospectively collected data from 69 patients (74 hips) who were treated with cementless THA using medial protrusio technique (MPT) or structural autologous bone-grafting technique (SABT).

[Emission Inventory of Anthropogenically Sourced VOCs and Its Contribution to Ozone Formation in Jiangsu Province].

Based on statistical activity data, emission factors, and source profiles, an emission inventory of anthropogenic-speciated VOCs in Jiangsu province in 2015 was calculated. The ozone formation potential (OFP) of VOCs was estimated by the maximum incremental reactivity (MIR). The result showed that the total anthropogenic emission amount of VOCs in Jiangsu Province was 1927.
