Objective: To investigate the skill and evaluate the accuracy for application of guide combined with probing the internal wall of pedicle screw trajectory for subaxial cervical pedicle screw placement.
Methods: Subaxial cervical pedicle screw was inserted in 11 patients by the guide combined with probing the internal wall of pedicle screw trajectory from January 2014 to October 2016, including 7 males and 4 females with an average age of 48.1 years(ranged 32 to 63 years).
Objective: To investigate clinical effects of strategy by stages for preventing respiratory complications of patients with acute cervical spinal cord injury (ACSCI).
Methods: From September 2009 to May 2013,the clinical data of 91 patients with ACSCI underwent surgery were retrospectively analyzed. Among the patients, 42 patients were divided into in-stages group, including 30 males and 12 females with an average age of 50 years old (ranged 28 to 76) which were treated with strategy by stages for preventing respiratory complications; others 49 patients which were not treated with the strategy regarded as control group, including 38 males and 11 females with an average age of 47 years old (ranged 30 to 77).
Objective: To investigate clinical features and treatments of cervical spinal injury in aged patients.
Methods: From July 2006 to October 2011, 27 patients with cervical spinal cord injury were divided into experiment group, including 20 males and 7 females with an average age of 69 years old (ranged 65 to 78 years old). The other 22 patients with the same degree of cervical spianl cord injury and the same period hospitalization were chosen to regard as control group, including 16 males and 6 females with an average age of 47 years old (ranged 38 to 65 years old).
Objective: To evaluate clinical effects of pedicle fixation without bone fusion in treating thoracolumbar fractures through paraspinal approach.
Methods: From January 2006 to January 2009, 25 patients (15 males and 10 females) with thoracolumbar fractures were treated. The average age was 39.
Objective: To establish an in vitro model of natural degeneration of lumbar endplate chondrocytes and explore the role and the expression change of Sox9 gene, an important gene in the differentiation and maturation of chondrocyte, in the process of natural degeneration of endplate chondrocytes.
Methods: The lumbar vertebrae of 35 SD rats were taken out to obtain the endplates. Endplate chondrocytes were isolated by enzyme digestion and cultured so as to establish an in vitro natural degeneration model of chondrocytes.
