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.

Expression and significance of calreticulin in human osteosarcoma.

Background: As one of the endoplasmic reticulum proteins, calreticulin (CRT) plays a significant role in the body, and it has been used by many researchers as a target for anti-tumor therapy.

Objective: The main purpose of the present study was to study expression of CRT of human osteosarcoma, and analyze the distinctions between normal and tumor tissues, pre- and post-chemotherapy patients, and metastatic and non-metastatic tumors in respect to this expression.

Methods: Immunofluorescent staining was used in order to investigate expression of CRT in diverse tissues.

Lumbopelvic fixation for multiplanar sacral fractures with spinopelvic instability.

Sacral fractures with both transverse and bilateral vertical fracture components are by definition multiplanar fractures, and often present with spinopelvic instability and cauda equina deficits. The treatment is challenging. Between 2006 and 2009, we treated nine such patients at our trauma centre.
