The relationship between humeral head angulation and bone void within the humeral head in proximal humerus fractures.

Background: The variability of humeral head angulation in proximal humerus fractures (PHFs) is a noteworthy observation. The purpose of this study was to investigate the potential association between humeral head angulation and bone void within the humeral head in PHFs.

Methods: We used the reconstruction function in Mimics software to generate three-dimensional models of fractures.

The clinical effects of artificial dermis in the treatment of skin and soft tissue defects accompanied by bone or tendon exposure.

Objective: The clinical effects of artificial dermis in treating skin and soft tissue defects accompanied by bone or tendon exposure were assessed.

Approach: A retrospective analysis was conducted on the clinical data of 45 cases of skin and soft tissue defects accompanied by bone or tendon exposure admitted to the trauma surgery department of Fujian Provincial Hospital between February 2018 and August 2020. They were divided into the artificial dermis and control groups.

All-Inside Anterior Cruciate Ligament Reconstruction Had Clinical Outcome Similar to the Transtibial Technique Except for Improved Side-to-Side Difference and Tegner Activity Scale: A Systematic Review and Meta-analysis.

Purpose: To compare clinical outcomes of the all-inside technique with the transtibial technique in anterior cruciate ligament reconstruction based on available literature on this topic.

Methods: According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist, we conducted a systematic search for randomized controlled trials and cohort studies. Our comprehensive search encompassed PubMed, Embase, Cochrane Library, and Web of Science.

Administration with curcumin alleviates spinal cord ischemia-reperfusion injury by regulating anti-oxidative stress and microglia activation-mediated neuroinflammation via Nrf2/NF-κB axis.

Spinal cord ischemia-reperfusion injury (SCII) ranks as the common complication after aortic surgery, usually leading to devastating post-operative paraplegia. Microglia over-activation and neuronal cell loss are key pathological features of SCII. Curcumin is involved in several I/R injuries.

Treatment of Distal Third Humeral Shaft Fracture with Intramedullary Nail Combined with Anterior Minimally Invasive Plate Osteosynthesis.

Objective: The treatment of distal third humeral shaft fracture is difficult. Studies have shown that anterior minimally invasive plate has lower probability of complication and higher healing rate. However there is no applicable anatomical plate at present.

Anatomic Double-Bundle and Single-Bundle Reconstructions Yield Similar Outcomes Following Anterior Cruciate Ligament Rupture: A Systematic Review and Meta-analysis.

Purpose: To evaluate outcomes of arthroscopic single-bundle (SB) versus anatomic double-bundle (ADB) anterior cruciate ligament reconstruction (ACLR) in adults through a synthesis of randomized controlled trials (RCTs). We hypothesized that SB and ADB methods would lead to similar outcomes after reconstruction of ACL rupture.

Methods: The Preferred Reporting Items for Systematic Reviews and Meta-analyses checklist guided our reporting.

Comparison of the effectiveness of oblique and transverse incisions in the treatment of fractures of the middle and outer third of the clavicle.

Background: Iatrogenic supraclavicular nerve injury is frequent during surgical repair of clavicle fractures through a transverse incision. The use of an oblique incision may be a potential approach to avoiding this complication. This study compared the clinical effectiveness of oblique and transverse incisions in the treatment of fractures in the middle and outer thirds of the clavicle.

Flexible construction of cellulose photonic crystal optical sensing nano-materials detecting organic solvents.

We developed a simple and efficient method to construct 3D and 2D opal and inverse opal cellulose photonic crystal films (CPCF) by embedding 3D or 2D polymethyl methacrylate (PMMA) colloidal arrays into carboxymethyl cellulose (CMC), respectively. The morphology and optical performance of CPCFs were characterized by SEM, diffraction spectra, Debye rings, and structural color. The brilliant structural colors of CPCFs are visible to the eye in the entire visible spectrum, and can be tuned by changing the particle diameters or the pore sizes.

Inhibition of the NMDA receptor protects the rat sciatic nerve against ischemia/reperfusion injury.

Inhibition of the N-methyl-D-aspartate (NMDA) receptor by MK-801 reduces ischemia/reperfusion (I/R) injury in the central nervous system. However, few previous studies have evaluated the neuroprotective effects of MK-801 against peripheral I/R injury. The present study aimed to investigate the protective effects of MK-801 pretreatment against I/R injury in the rat sciatic nerve (SN).

Minimally invasive plate osteosynthesis of acetabular anterior column fractures using the two-incision minimally invasive approach and a preshaped three dimension plate.

Purpose: To investigate the treatment of acetabular anterior column fractures using a two-incision minimally invasive (TIMI) approach and minimally invasive plate osteosynthesis (MIPO) technique using a preshaped 3D plate.

Methods: A group of 12 consecutive cases of acetabular fractures from March 2013 to July 2014 were treated with the TIMI approach. 3D mirror models of the uninjured side of the hemipelvis were printed preoperatively; the plates used in surgery were preshaped according to these models.

Treatment of Middle-up Part Long-segment Femoral Fracture with Long Proximal Femoral Nail Antirotation.

Objective: To investigate the outcomes of treating middle-up part long-segment fractures of the femur by long proximal femoral nail antirotation (PFNA-long).

Methods: From June 2006 to December 2013, 139 cases (35 women, 104 men; mean age 48.8, range, 18-86 years) of long-segment femoral fracture in middle-up part were treated with long proximal femoral nail antirotation (PFNA, 320-380 mm) by minimally invasive percutaneous fixation and autogenous iliac bone graft.

Treatment of long-segment fracture at middle-up part of femur with long proximal femoral nail antirotation.

Objective: To investigate the results of non-invasive operation method and evaluate clinical and radiological outcome of long proximal femoral nail antirotation in treating long-segment fracture at middle-up part of femur.

Methods: The retrospective study was conducted at the Second Hospital of Fuzhou, China, and comprised cases of long-segment fracture in middle-up part of femur power treated with long proximal femoral nail antirotation between June 2006 and December 2013. The patients were followed up for a minimum of 9 months.

[Microsurgical one-stage repair of hand flexor tendon injuries and rehabilitation: a report of 97 cases].

Objective: To investigate the therapeutic effects of microsurgical one-stage repair of hand flexor tendon injuries.

Methods: Among 97 patients with (182 flexor tendons) hand injuries, 59 patients were male and 38 patients were female, ranging in age from 6 to 65 years, with an average of 32 years. Twenty-two patients got injuries by glasses, 32 patients got injuries by knife, 29 patients got injuries by saw, and 14 patients got crush injuries.
