[Treatment of open fracture bone defect of distal femur with antibiotic cement column and bone graft].

Objective: To investigate the efficacy of antibiotic cement column combined with iliac bone graft in the treatment of open fracture with bone defect of distal femur.

Methods: From October 2014 to March 2021, 16 patients of open fracture bone defect of distal femur were treated with antibiotic bone cement column and iliac bone graft, including 12 males and 4 females. The age ranged from 28 to 68 years old.

Comparison of Locking Plate Alone and Locking Plate Combined with 3D Printed Polymethylmethacrylate Augmentation in Treating Proximal Humerus Fractures in the Elderly.

Background: Locking plates are widely used in open reduction internal fixation (ORIF) for proximal humeral fracture (PHF). However, the optimal surgical treatment of unstable, displaced PHF in elderly patients remains controversial. This study aimed to compare the radiological and clinical outcomes of surgical treatment of PHF in the elderly with locking plate (LP) alone and locking plate combined with 3D printed polymethylmethacrylate (PMMA) prosthesis augmentation (LP-PA).

Clinical Observations of Kümmell Disease Treatment Through Percutaneous Fixation Combined with Vertebroplasty.

Objective: To explore the safety and efficacy of percutaneous pedicle screw fixation combined with vertebroplasty for the treatment of stage III Kümmell disease.

Methods: The clinical data and follow-up results of 22 patients with Kümmell disease who were admitted to our department from 2014 to 2018 were analyzed. There were 14 females and eight males, and the Age range was 58-81 years.

[Clinical outcomes of buttress plating in treating posterior Pilon fractures through modified posteromedial approach].

Objective: To explore clinical outcomes of buttress plating in treating posterior Pilon fracture by amodified posteromedial approach.

Methods: From July 2014 to January 2015, 10 patients with posterior Pilon fracture were respectively analyzed, including 7 females and 3 males, aged from 31 to 54 years old. One patient were type , 3 patients were type IIand 6 patients were type III according to classification of Pilon fracture by YU Guang-rong.

[Treatment of chronic anterolateral ankle instability by reconstructing lateral ligament with semitendinosus autograft].

Objective: To investigate clinical effects of chronic anterolateral ankle instability by reconstructing lateral ligament with semitendinosus autograft.

Methods: From September 2014 to November 2016, 28 patients with chronic anterolateral ankle instability underwent lateral ligament reconstruction with semitendinosus autograft. Among them, including 20 males and 8 females with an average age of 28.

[Progress on diagnosis and treatment for chronic ankle instability].

Chronic ankle instability is a common disease which is caused by missed diagnosis or inappropriate treatment of acute ankle sprain. It could lead to long-term pain, traumatic arthritis and malfunctions. While the consistent standard for its diagnosis and treatment has not yet formed.

Application of Computed Tomography Processed by Picture Archiving and Communication Systems in the Diagnosis of Acute Achilles Tendon Rupture.

The applications of CT examination in the diagnosis of the acute Achilles tendon rupture (AATR) were investigated. A total of 36 patients with suspected acute Achilles tendon rupture were tested using physical examination, ultrasound, and 3DCT scanning, respectively. Then, surgery was performed for the patients who showed positive result in at least two of the three tests for AATR.

Effect of cytokines on liver necrosis.

AIM:To investigate the effect of cytokines on the liver necrosis.METHODS: rIL (interleukin)-1, rIL-6, rIFN (interferon), rTNF (tumor necrosis factor) -alpha with or without D-galactosamine (D-GAL) were injected into the abdominal cavity of mice separately.ALT, TBIL (total bilirubin) and histological changes were observed.
