Background: Anterior lumbar interbody fusion (ALIF) for lumbar interbody fusion from L2 to the sacrum has been an established technique for decades.
Objectives: The advantages and disadvantages of ALIF compared to posterior interbody fusion techniques are discussed. The operative technique is described in detail. Complications and avoidance strategies are discussed.
Material And Methods: This article is based on a selective literature search using PubMed and the experience of the authors in this medical field.
Results: The advantages of ALIF compared to posterior fusion techniques are the free approach to the anterior disc space without opening of the spinal canal or the neural foramina. This gives the possibility of an extensive anterior release and placement of the largest possible cages without the risk of neural structure damage. The disadvantages of ALIF are the additional anterior approach and the related complications. The most frequent complication is due to damage of vessels. The rate of complications is significantly increased in revision surgery.
Conclusion: The ALIF technique meaningfully expands the repertoire of the spinal surgeon especially for the treatment of non-union after interbody fusion, in patients with epidural scar tissue at the index level and spinal infections. Advantages and disadvantages should be considered when evaluating the indications for ALIF.

Nanjing TCM Hospital Affiliated to Nanjing University of Traditional Chinese Medicine, 157 Daming Road, Nanjing, Qinhuai District, 210022, China.
To systematically evaluate the differences in the clinical efficacy of lumbar degenerative disorders (LDDs) treatment between oblique lumbar interbody fusion with percutaneous pedicle screw fixation (OLIF-PF), OLIF stand-alone (OLIF-SA), and OLIF with anterolateral screw fixation (OLIF-AF). A systematic search was conducted on both English and Chinese databases, wherein the literature was screened based on title, abstract, and full text. Literature that met the inclusion criteria was assessed for quality and relevant information was extracted.

Department of Orthopedics, Brown University, Providence, RI.
Study Design: Retrospective cohort study.
Objective: Evaluate the utility of Delirium Risk Assessment Score (DRAS), Delirium Risk Assessment Tool (DRAT), and Delirium Elderly At-Risk (DEAR) in patients undergoing posterior lumbar interbody fusions.
Background: Surgical interventions can place patients at risk for postoperative delirium (POD), an acute and often severe cognitive impairment associated with poor outcomes.
Background: To compare the effect of minimally invasive and open transforaminal lumbar interbody fusion (TLIF) approaches in fusing the L4-L5 segment and predicting the potential risk of adjacent segment degeneration (ASD).
Methods: A computed tomography scan image was processed and the three-dimensional model of the L1-L5 spine was reconstructed. The minimally invasive and Open TLIF finite element models were constructed.
A Rare Case of Bilateral Foot Drop Following Cervical Decompression in Tandem Spinal Stenosis.

Orthopaedic Surgery, Ng Teng Fong General Hospital, Singapore, SGP.
This case report describes a 70-year-old male presenting with limb weakness, urinary retention and tandem cervical and lumbar spinal stenosis with complicating white cord syndrome, a rare reperfusion injury post decompression surgery. Initially admitted following an unwitnessed fall, the patient's neurological examination indicated that progressive weakness of the limbs and sensory loss etiology is cervical and lumbar spondylosis with severe spinal canal stenosis, confirmed by imaging. Due to rapid deterioration, he underwent C5 corpectomy, cervical decompression and fusion.
