The Effect of Arthroscopic Extra-Articular Entire Coracohumeral Ligament Release for Patients with Recalcitrant Frozen Shoulder.

Objective: The thickened coracohumeral ligament (CHL) is an important part of the typical manifestations and magnetic resonance imaging of frozen shoulder. However, only a few clinical studies with limited cases on arthroscopic extra-articular entire CHL release exist in the literature. This study was to evaluate the effect of arthroscopic extra-articular entire CHL release for patients with recalcitrant frozen shoulder.

Clinical Study of Wrist Arthroscopy Combined with Oblique Ulnar Shortening Osteotomy in the Treatment of Ulnar Impaction Syndrome.

Objective: To explore the clinical effects of wrist arthroscopy combined with oblique ulnar shortening osteotomy in the treatment of ulnar impaction syndrome.

Methods: This was a retrospective study of 60 patients with ulnar impaction syndrome who were admitted to our department from January 2016 to December 2019. According to different surgical methods, they were divided into an observation group and a control group, with 30 cases in each group.

Combined transcriptome and metabolome integrated analysis of Acer mandshuricum to reveal candidate genes involved in anthocyanin accumulation.

The red color formation of Acer mandshuricum leaves is caused by the accumulation of anthocyanins primarily, but the molecular mechanism researches which underlie anthocyanin biosynthesis in A. mandshuricum were still lacking. Therefore, we combined the transcriptome and metabolome and analyzed the regulatory mechanism and accumulation pattern of anthocyanins in three different leaf color states.

[Anatomical repair of Atzei-EWAS type 2 triangular fibrocartilage complex injury under wrist arthroscopy].

Objective: To explore the effectiveness of anatomical repair of Atzei-EWAS type 2 triangular fibrocartilage complex (TFCC) injury under wrist arthroscopy.

Methods: Between March 2018 and March 2020, 16 patients with Atzei-EWAS type 2 TFCC injury were admitted, and the TFCCs were anatomically repaired with a three-dimensional suture with a thread anchor under wrist arthroscopy. There were 10 males and 6 females with an average of 40.

Three-Dimensional Printing-Assisted Masquelet Technique in the Treatment of Calcaneal Defects.

Objective: The aim of the present study was to summarize the clinical efficacy of three-dimensional (3D) printing technology combined with the Masquelet technique in the treatment of calcaneal defects.

Methods: From January 2018 to April 2019, 3D printing combined with induced masquelet technology was used to treat four patients with calcaneal defects, including two men and two women. The patients were aged 22-52 years old, with an average age of 36 years.

[Treatment of the fifth metacarpal neck fracture with elastic intramedullary nail under the guidance of high frequency ultrasound].

Objective: To analyze the feasibility and effectiveness of elastic intramedullary nail fixation for the fifth metacarpal neck fracture under the guidance of high frequency ultrasound.

Methods: The clinical data of 30 patients with the fifth metacarpal neck fractures who were treated with elastic intramedullary nails fixation under the guidance of high frequency ultrasound and met the selection criteria between May 2013 and September 2017 were retrospectively analysed. There were 24 males and 6 females, the age ranged from 18 to 58 years, with an average of 31.
