[Comparative study on curative effect of minimally invasive locking plate for the treatment of intra-articular calcaneal fractures via sinus tarsi approach].

Objective: To compare clinical efficacy of minimally invasive locking plate and anatomic locking plate in treating intra-articular calcaneal fractures via sinus tarsi approach.

Methods: A retrospective analysis was conducted of 48 patients with intra-articular calcaneal fractures treated with surgery via sinus tarsi approach from July 2016 to June 2017. According to differernt methods of internal fixation, the patients were divided into minimally invasive locking plate group and anatomic locking plate group.

Administration of mircoRNA-135b-reinforced exosomes derived from MSCs ameliorates glucocorticoid-induced osteonecrosis of femoral head (ONFH) in rats.

Exosomes were found to exert a therapeutic effect in the treatment of osteonecrosis of the femoral head (ONFH), while miR-135b was shown to play an important role in the development of ONFH. In this study, we investigated the effects of concomitant administration of exosomes and miR-135b on the treatment of ONFH. A rat mode of ONFH was established.

[Case-control study on minimally invasive surgery and conventional open plating for displaced midshaft clavicular fracture based on 3D-print].

Objective: To compare clinical effect of minimally invasive surgery and conventional open plating for acute displaced midshaft clavicle fracture based on 3D-print.

Methods: From July 2016 and December 2016, 40 patients with acute displaced midshaft clavicle fractures were retrospectively analyzed. The patients were divided into 3D minimally invasive surgery group (group A) and conventional open plating group (group B) according to different surgical incisions and whether to use 3D printing.

Comparison of post-operative numbness and patient satisfaction using minimally invasive plate osteosynthesis or open plating for acute displaced clavicular shaft fractures.

Background: Anterior chest wall numbness after plate fixation of clavicular shaft fractures is a common complication. This is usually related to damage of the branches of the supraclavicular nerve in conventional open plating. We investigated whether the use of minimally invasive plate osteosynthesis could reduce the incidence of post-operative numbness and improve patients' satisfaction compared to open plating.

[Comparison of internal fixation and semi-shoulder arthroplasty in treating proximal humerus comminuted fractures in elderly].

Objective: To explore clinical effectiveness of internal fixation and semi-shoulder arthroplasty in treating proximal humerus comminuted fractures in elderly.

Methods: From October 2009 and October 2011, 32 patients aged over 60 years old with three and four-part fractures of proximal humeral were treated with internal fixation (20 cases) and semi-shoulder arthroplasty (12 cases). In internal fixation group, there were 6 males and 14 females aged from 63 to 82 years old (ranged, 71.
