Construction and validation of a nomogram for blood transfusion after open reduction and internal fixation (ORIF) of proximal humeral fractures in the elderly: a cross-sectional study.

Purpose: Few studies have focused on the risk factors leading to postoperative blood transfusion after open reduction and internal fixation (ORIF) of proximal humeral fractures (PHFs) in the elderly. Therefore, we designed this study to explore potential risk factors of blood transfusion after ORIF for PHFs. We have also established a nomogram model to integrate and quantify our research results and give feedback.

Asperosaponin VI promotes angiogenesis and accelerates wound healing in rats via up-regulating HIF-1α/VEGF signaling.

Wound therapy remains a clinical challenge due to the complexity of healing pathology and high demand of achieving functional and aesthetically satisfactory scars. Newly formed blood vessels are essential for tissue repair since they can support cells at the wound site with nutrition and oxygen. In this study, we investigated the effects of Asperosaponin VI (ASA VI) isolated from a traditional Chinese medicine, the root of Dipsacus asper Wall, in promoting angiogenesis, as well as its function in wound therapeutics.

[Bone substitutes augmentation combined with internal fixation versus internal fixation alone in treating proximal femoral fractures in the elderly: a meta-analysis].

Objective: To systematically review the effectiveness of bone substitute augmentation combined with internal fixation versus internal fixation alone in treating proximal femoral fractures in the elderly.

Methods: Subject term and keywords were searched from Pubmed, Cochrane databases and CNKI from database foundation to August 2015. Randomized controlled studies and qusi-randomized controlled studies on bone substitutes augmentation combined with internal fixation versus internal fixation alone for the treatment of proximal femoral fractures in the elderly were chosen.

[Delayed union or nonunion of the ulna after intramedullary nailing for pediatric forearm fractures].

Objective: To analyze the causes of delayed union or nonunion of the ulna after intramedullary nailing in pediatric forearm fractures.

Methods: From February 2005 to February 2010,5 patients with forearm fractures who were treated with titanium elastic nailing (TEN) were identified to fulfill the criteria of having developed a delayed union or nonunion of the ulna. The causes of delayed union or nonunion were investigated according to mechanism of injury, fracture location, treatments methods and postoperative management.

Comparison of Pediatric Forearm Fracture Fixation Between Single- and Double-Elastic Stable Intramedullary Nailing.

The purpose of this study was to evaluate and compare the outcome of single- and double-elastic stable intramedullary nailing (ESIN) for the treatment of pediatric both-bone forearm fractures. We retrospectively analyzed 49 children with both-bone forearm fractures treated with ESIN. Twenty-four patients were treated with single-ESIN (S-ESIN) to fixate the radius only, and the other 25 patients were treated with double-ESIN (D-ESIN) to fixate the radius and ulna.

[Comparison of two minimally invasive internal fixed methods for the treatment of distal tibio-fibula fractures].

Objective: To compare the outcome of two minimally invasive internal fixed methods for the treatment of distal tibio-fibula fractures.

Methods: The clinical data of 50 patients with distal tibio-fibula fractures from March 2006 to March 2009 was analyzed retrospectively. Twenty-eight patients were treated with minimally invasive percutaneous locking compression plate fixing tibia combining elastic stable intramedullary nailing fixing fibular (Group P + E).

[Mid-term outcomes of minimally invasive transforaminal lumbar interbody fusion with unilateral pedicle screw fixation for lower lumbar degenerative diseases].

Objective: To evaluate the mid-term clinical outcomes of minimally invasive transforaminal lumbar interbody fusion (TLIF) with unilateral pedicle screw fixation for lower lumbar degenerative diseases.

Methods: From April 2004 to December 2005, minimally invasive TLIF through paramedian approach with unilateral pedicle screw fixation was performed in a consecutive series of 43 patients, including 24 male and 19 female, aging from 38 to 71 years, with an average age of 49 years. The length of surgical incision was 3 cm.
