Review Meta Analysis
Surgical techniques and perioperative surgical outcomes after discectomy for calcified lumbar disc herniation: a review and meta-analysis.
Calcified lumbar disc herniation (CLDH) poses surgical challenges due to longstanding disease and adherence of herniated disc to the surrounding neural structures. The data regarding outcomes after surgery for CLDH are limited. This review was conducted to analyse the surgical techniques, perioperative findings and the postoperative clinical outcomes after surgery for CLDH. ⋯ Surgical difficulties in CLDH cases leads to increase in operative time compared to NCLDH. Good clinical outcomes can be obtained with careful planning; the focus of surgery should be on decompression of the neural structures rather than disc removal.

To determine the predictive effect of Hounsfield unit (HU) values in the cervical vertebral body measured by computed tomography (CT) and T-scores measured by dual-energy X-ray absorptiometry (DXA) on Zero-P subsidence after anterior cervical discectomy and fusion (ACDF)with Zero-P. In addition, we evaluated the most reliable measurement of cervical HU values. ⋯ Lower cervical HU value indicates a higher risk of subsidence in patients following Zero-P fusion for single-level cervical spondylosis. HU values were better predictors of Zero-P subsidence than DXA T-scores. In addition, the measurement of HU value in the midsagittal, midcoronal, and midaxial planes of the cervical vertebral body provides an effective method for predicting Zero-P subsidence.

Review Meta Analysis
Iliac crest bone graft versus cell-based grafts to augment spinal fusion: a systematic review and meta-analysis.
Despite successful fusion rates with iliac crest bone graft (ICBG), donor-site morbidity and increased operating time remain a considerable limitation and drive the search for alternatives. In this systematic review, grafts with additional cellular supplementation were compared with ICBG for spinal arthrodesis. We compared safety, efficacy and long-term outcomes, thus providing the current and relevant evidence for orthopaedic surgeons to make informed choices regarding this rapidly developing field. ⋯ Cell-based therapy offers a promising alternative to ICBG in spinal fusion surgery, which could help reduce the associated morbidity to patients. This review found that cell-based therapy is non-inferior to iliac crest bone graft and may offer patients an alternative treatment option with fewer complications and reduced post-operative pain. However, the literature to date is limited by heterogeneity of the cell preparation and grafting process. Future research with a unified approach to the cell preparation process is required to fully delineate the potential advantages of this technology.

Review Meta Analysis
Clinical validation of grouping conservative treatments in neck pain for use in a network meta-analysis: a Delphi consensus study.
A network meta-analysis aims to help clinicians make clinical decisions on the most effective treatment for a certain condition. Neck pain is multifactorial, with various classification systems and treatment options. Classifying patients and grouping interventions in clinically relevant treatment nodes for a NMA is essential, but this process is poorly defined. ⋯ With this consensus we clinically validated two neck pain classifications and grouped conservative treatments into 17 well-defined and clinically relevant nodes.

To identify how pre-surgical conservative care is characterized and reported in randomized controlled trials of adults undergoing elective lumbar fusion, including duration and type of treatment. ⋯ Although roughly two-thirds of trials reported that patients failed conservative care prior to receiving a lumbar fusion, few studies named the conservative intervention provided and no studies provided any details regarding dosing or recency of care. This lack of information creates ambiguity in the surgical decision-making process, setting the assumption that all patients received adequate conservative care prior to surgery. Details about pre-surgical conservative care should be disclosed to allow for appropriate clinical application, decision-making, and interpretation of treatment effects.
