Comparative StudyCorrelation between radiculalgia and counts of T lymphocyte subsets in the peripheral blood of patients with lumbar disc herniation.
To determine the correlation between the degree of radiculalgia and counts of T lymphocyte subsets in the peripheral blood of patients with lumbar disc herniation. ⋯ Our results suggest that changes in T lymphocyte subsets in peripheral blood take place after prolapse of lumbar intervertebral discs. The current results may provide support for involvement of immunologic mechanisms in low back pain secondary to herniation of the lumbar disc. T lymphocytes may play an important role in the development of symptoms in patients with lumbar intervertebral disc herniation.

Comparative StudyOne-stage anterior release and reduction with posterior fusion for treatment of irreducible atlantoaxial dislocation.
To analyze the approach and feasibility of one-stage anterior release and reduction with posterior fusion for irreducible atlantoaxial dislocation. ⋯ Treatment of irreducible atlantoaxial dislocation with one-stage anterior release and reduction with posterior fusion is a reliable method.

Comparative StudyTreatment of aseptic nonunion after intramedullary nailing fixation with locking plate.
To evaluate the safety and efficacy of locking plate combined with bone grafting in the treatment of aseptic nonunion following intramedullary nailing fixation of fractures of the long bones. ⋯ Locking plate fixation combined with bone grafting is a highly effective treatment for aseptic nonunions of the long bones after intramedullary nailing fixation, especially in the case of metaphyseal nonunion.

Comparative StudyInterbody cage support improves reconstruction of sagittal balance after anterior selective fusion in Lenke type 5 idiopathic scoliosis patients.
To investigate the effect of interbody cage support on reconstruction of the sagittal profile after anterior selective correction in Lenke type 5 adolescent idiopathic scoliosis (AIS) patients. ⋯ Anterior selective single rod instrumentation and fusion is a recommended method for Lenke type 5C AIS. A structural interbody cage does not appear to improve the regional profile, nor the profiles in the instrumented area and the adjacent proximal and distal segments; yet could result in a better total balance in the long-term.

Comparative StudyImaging study of wedge changes in the vertebral bodies and intervertebral discs in adolescent idiopathic scoliosis.
To observe wedge changes in the vertebral bodies and intervertebral discs in progressive adolescent idiopathic scoliosis before and after conservative treatment with braces, and to explore the correlation between wedge changes in the vertebral bodies or intervertebral discs and scoliosis curves. ⋯ Wedge changes in the vertebral bodies and intervertebral discs have a positive correlation with degree of curve, which indicates that asymmetric growth of the cartilaginous endplate might be the primary cause of wedge change in the vertebral bodies.
