Prevention of proximal junctional kyphosis after posterior surgery of Scheuermann kyphosis: an operative technique.
A prospective randomized study. ⋯ This study introduces a new technique that may have an effect in preventing PJK. Our results seem to be satisfactory, but additional studies with more patients and longer follow-up times are needed to further delineate the feasibility of this technique.

Time to development, clinical and radiographic characteristics, and management of proximal junctional kyphosis following adult thoracolumbar instrumented fusion for spinal deformity.
A retrospective review. ⋯ The patients in this series who developed PJK had substantial preoperative positive sagittal malalignment that remained inadequately corrected following surgery, likely resulting from a combination of inadequate surgical correction and a significant compensatory increase in thoracic kyphosis. In the absence of direct relationship between a greater PJK angle and worse clinical outcome, clinical symptoms and neurological status rather than absolute reliance on radiographic parameters should drive the decision to pursue revision surgery.

Prognostic factors for surgical outcomes including preoperative total knee replacement and knee osteoarthritis status in female patients with lumbar spinal stenosis.
A retrospective clinical case series. ⋯ A poor preoperative functional score, the presence of preoperative KOA, and longer operational levels were shown to be poor prognostic factors for the 1-year surgical outcome of LSS. Also, patients in the TKR group showed the worst ODI scores at preoperative and postoperative 1-year evaluations. Consideration of these factors when planning for spine surgery could be helpful in predicting the surgical outcomes of lumbar spinal surgery.

Randomized Controlled TrialCT-guided nucleoplasty with radiofrequency energy for the treatment of lumbar disk herniation.
A clinical randomized controlled trial. ⋯ The results of this study suggest that CT-guided nucleoplasty with radiofrequency energy is a relative effective and safe technique for treating leg pain caused by radicular encroachment. Furthermore, nucleoplasty combined with nerve root injection had achieved a significant greater improvement in pain management and functional level in short term (within 1 mo) after treatment than nucleoplasty alone.

Comparative StudyA comparison of cell salvage strategies in posterior spinal fusion for adolescent idiopathic scoliosis.
Retrospective case-control study. ⋯ The present study demonstrates the efficacy of a combined intraoperative and postoperative cell salvage strategy in PSF for AIS, significantly reducing perioperative donor blood transfusions, maintaining physiological Hct, and conserving blood bank resources.
