Combined Medial and Lateral Approach Versus Paratricipital Approach in Open Reduction and Internal Fixation for Type C Distal Humerus Fracture: A Randomized Controlled Study.

Objective: Olecranon osteotomy and paratricipital approaches were widely used in the treatment of type C distal humerus fracture but some disadvantages exist, so a combined medial and lateral approach was designed. The objective of this study was to investigate and compare the clinical outcomes of combined medial and lateral approach with the paratricipital approach in open reduction and internal fixation of type C distal humerus fractures.

Methods: From May 2018 to April 2020, 37 patients with type C distal humerus fracture who accepted open reduction and internal fixation in our hospital were enrolled in this study.

Surgical Treatment of Internal Fixation Failure of Femoral Peritrochanteric Fracture.

Objective: To investigate the factors, surgical treatment methods and clinical effect of internal fixation failure of intertrochanteric and subtrochanteric fractures.

Methods: From June 2015 to May 2019, arthroplasty and internal fixation revision were used to treat 18 cases of internal fixation failure of intertrochanteric and subtrochanteric fractures. There were 10 males and eight females, with an average age of 67.

Appropriate excision time of heterotopic ossification in elbow caused by trauma.

Objective: The aim of this study was to investigate the optimal timing for the resection of heterotopic ossification (HO) of the elbow.

Methods: We retrospectively reviewed 42 patients who were treated operatively for heterotopic ossification of the elbow from March 2010 to December 2014 at our institution. The patients were divided into early (before 12 months) and late (after 12 months) excision groups.

Combination of granulocyte colony-stimulating factor and CXCR4 antagonist AMD3100 for effective harvest of endothelial progenitor cells from peripheral blood and in vitro formation of primitive endothelial networks.

Endothelial progenitor cells (EPC) derived from the circulation may be used to enhance neovascularization. Since the combination of granulocyte colony-stimulating factor (GCSF) and CXCR4 antagonist AMD3100 efficiently mobilizes hematopoietic stem cells into peripheral circulation, it may increase the pool of endogenously circulating EPC. We tested this hypothesis by administering GCSF and AMD3100 to adult rabbits and rats, isolating mononuclear cells from peripheral blood by Ficoll density gradient centrifugation, and characterizing the blood-derived EPC based on morphology, immunophenotyping, gene expression and other functional analyses.

Coculture of peripheral blood-derived mesenchymal stem cells and endothelial progenitor cells on strontium-doped calcium polyphosphate scaffolds to generate vascularized engineered bone.

Vascularization of engineered bone tissue is critical for ensuring its survival after implantation and it is the primary factor limiting its clinical use. A promising approach is to prevascularize bone grafts in vitro using endothelial progenitor cells (EPC) derived from peripheral blood. Typically, EPC are added together with mesenchymal stem cells (MSC) that differentiate into osteoblasts.

[Surgical treatment of sinus tract in diabetic foot with adjacent pedicle fascia flap and arthrodesis].

Objective: To study the therapeutic effect of adjacent pedicle fascia flap filling and arthrodesis in the regional management of sinus tract in diabetic foot.

Methods: From February 2007 to August 2010, 6 patients suffering diabetic foot with sinus tract were included. There were 4 male and 2 female patients, aged 47 to 68 (averaging 58.

[Managements of open wounds from an earthquake].

Objective: To explore the surgical managements of open wounds from 5·12 Wenchuan Earthquake.

Methods: In this report, fifty one patients with open wounds were treated after transported into West China Hospital from May 12 to 26 in 2008 after 5·12 Wenchuan Earthquake. Among 51 cases, open wounds were due to open fractures (n = 8), fasciotomy (n = 6), exposed bone (n = 8) and defects of skin and soft tissue (n = 29).

[Percutaneous screw fixation for pelvic fractures with fluoroscopy-based navigation].

Objective: To investigate the applications of fluoroscopy-based navigation in pelvic fractures and related surgical considerations.

Methods: From May 2010 to December, 16 patients with pelvic fractures were treated with computerized navigation. There were 12 males and 4 females with an average age of 37 years (ranged from 20 to 54 years).

[A medium-term analysis on of therapeutic effects of locking proximal humerus plate for the treatment of comminuted fractures of proximal humerus].

Objective: To investigate the medium-term curative effects of locking proximal humerus plate for the treatment of comminuted fractures of proximal humerus, and provide evidences for the clinical practice.

Methods: From August 2005 and April 2008, 23 patients with comminuted fractures of proximal humerus were treated with locking plates, including 12 males and 11 females, aged 27 to 76 years old (averaged 51.5 years old).

[Analysis of patients with bone injury in Wenchuan earthquake].

Objective: To evaluate the patients with bone injury in Wenchuan earthquake.

Methods: From May 12th to June 15th 2008 the data of 1410 patients with bone injury in Wenchuan earthquake were analyzed to evaluate clinical intervention and remedy-managing experience.

Results: The 1410 patients average age was from 4 to 103 years old.
