Introduction: Some cases of postoperative correction loss have been observed in the reduction of vertebral slippage using a percutaneous pedicle screw system for lumbar degenerative spondylolisthesis. We aimed to identify the risk factors for correction loss after minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and to determine the effect of postoperative correction loss on postoperative clinical outcomes.
Methods: In this retrospective study, a total of 111 patients (mean age 69.

Electronic-grade polycrystalline silicon of large size holds a crucial position in the semiconductor industry due to its extensive application prospects. This study aims to fill the gap in the atomic-level characterization of crystal defects within polycrystalline silicon. By employing focused ion beam technology for sample preparation and combining advanced scanning electron microscopy-electron backscatter diffraction technology with aberration-corrected transmission electron microscopy, we have uncovered that the silicon core of the polycrystalline silicon exhibits a single crystal structure and dense twinning within the polycrystalline matrix.

Background And Purpose: The effects of axial instability in the rod-screw interface resulting in axial slippage between screws and rods are largely unknown. We aimed to assess the incidence of axial slip and loss of correction by comparing tulip screw versus dual locking cup in spinal instrumentations of patients treated with posterior spinal fusion for adolescent idiopathic scoliosis (AIS). We also aimed to assess whether axial slip would affect health-related quality of life.

Purpose: There is growing evidence that after moderate and severe slipped capital femoral epiphysis (SCFE), in-situ fixation can result in femoroacetabular impingement (FAI). Several different realignment procedures have been described but their use remains controversial due to high complication rates and technical complexity. Our study aims to evaluate the radiological outcomes and complications of patients who underwent open reduction with subcapital shortening osteotomy for moderate or severe SCFE.

Study Design: Basic science.
Objective: To characterize robotically controlled cervical traction applied to intact and C4-C5 facet injury cadaveric models and compare the radiographic results with those of weight-pulley traction.
Summary Of Background Data: Manual application of weight-pulley cervical traction for dislocated facet reduction or cervical deformity correction has many limitations.
