Randomized Controlled Trial
An analysis of fusion cage migration in unilateral and bilateral fixation with transforaminal lumbar interbody fusion.
To investigate if instrumentation (unilateral vs. bilateral fixation) has an effect on the rate of fusion cage migration. ⋯ We conclude that unilateral fixation is not stable enough to prevent fusion cage migration in some patients who undergo TLIF.

Severe spinal deformity is a complex morphological deformation that occurs and develops in three-dimensional space combined with abnormal development and morphology of anatomical structures, which presents great difficulties in the process of transpedicular screw placement. This study tried to explore the methods of transpedicular screw placement in surgical correction of severe spinal deformities. ⋯ The five-step remedial method proved to be an effective supplementary method for transpedicular screw placement to treat patients with severe spinal deformities. The key points include a detailed preoperative plan, a meticulous hand drilling sensation, and an experienced probing technique for screw tract.

To investigate whether rs11190870 near LBX1 correlates with the susceptibility or curve progression of adolescent idiopathic scoliosis (AIS) in a Han Chinese population. ⋯ The SNP rs11190870 near LBX1 is associated with both susceptibility and curve progression of AIS.

To retrospectively evaluate the outcome of C1-2 transarticular screws combined with C1 laminar hooks fixation. ⋯ The C1-2 transarticular screws combined with C1 laminar hooks fixation is a reliable technique for atlantoaxial instability.

Posterior instrumented spinal fusion is indicated for progressive scoliosis that develops in Duchenne muscular dystrophy (DMD) patients. Whilst spinal fusion is known to improve quality of life, there is inconsistency amongst the literature regarding its specific effect on respiratory function. Our objective was to determine the effect of scoliosis correction by posterior spinal fusion on respiratory function in a large cohort of patients with DMD. Patients with DMD undergoing posterior spinal fusion were compared to patients with DMD not undergoing surgical intervention. ⋯ Severity of scoliosis was not a key determinant of respiratory dysfunction. Posterior spinal fusion did not reduce the rate of respiratory function decline. These two points suggest that intrinsic respiratory muscle weakness is the main determinant of decline in respiratory function in DMD.
