Cureus 2021 Aug 2;13(8):e16822. Epub 2021 Aug 2.

Neurological Surgery, University at Buffalo, Jacobs School of Medicine and Biomedical Sciences, Buffalo, USA.

Here we present a novel application of cortical bone trajectory (CBT) fixation utilizing robotic guidance in a previously instrumented spine with a traditional pedicle screw (PS), obviating the need for a larger posterior incision, reducing the risk of infection, muscular dissection, and likely decreasing hospital length of stay. A 60-year-old woman with prior left L3-L4 extreme lateral interbody fusion and unilateral percutaneous PS placed at L3 to L5 presented with progressive bilateral lower-extremity pain and diminished sensation in the S1 dermatome secondary to adjacent segment disease (ASD).

Pain Relief Salvage with a Novel Minimally Invasive Posterior Sacroiliac Joint Fusion Device in Patients with Previously Implanted Pain Devices and Therapies.

J Pain Res 2021 2;14:2709-2715. Epub 2021 Sep 2.

Department of Anesthesiology, University of Kansas Medical Center, Kansas City, KS, USA.

Background: Sacroiliac joint (SIJ) pain is a common cause of low back pain, a problem experienced by two-thirds of adults in the United States population. Traditionally, the management of persistent SIJ-related pain has involved conservative therapies (physical therapy, topical medications, oral anti-inflammatory medications), interventional therapies (SIJ steroid injections or ablation), and surgery (SIJ fusion; open and lateral approach). Recent advancements in technology have paved the way for SIJ fusion via a posterior approach, which aims to minimize complications and enhance recovery. Read More

Postoperative lumbar spine MRI: How well does a radiology report that raises suspicion for infection correlate with true clinical infection?

J Clin Neurosci 2021 Oct 31;92:6-10. Epub 2021 Jul 31.

Division of Neurosurgery, Maimonides Medical Center, 4802 10th Avenue, Brooklyn, NY, USA.

Introduction: Interpretation of a lumbar spine MRI in the immediate postoperative period is challenging, as postoperative tissue enhancement and fluid collections may be mistaken for infection. Radiology reports may use ambiguous language, creating a clinical problem for a surgeon in determining whether a patient needs treatment with antibiotics or revision surgery. Moreover, retrospective criticism of management in instances of a true infection may lead to medicolegal ramifications. Read More

Frailty is an Important Predictor of 30-day Morbidity in Patients Treated for Lumbar Spondylolisthesis Using a Posterior Surgical Approach.

Spine J 2021 Sep 6. Epub 2021 Sep 6.

Division of Neurosurgery, Department of Surgery, University of Toronto, Toronto, Ontario, Canada, M5T 2S8; Division of Neurosurgery, Krembil Neuroscience Centre, Toronto Western Hospital, University Health Network, Toronto, Ontario, Canada, M5T 2S8. Electronic address:

Background Context: Traditionally, a non-operative approach has been favored for elderly patients with lumbar spondylolisthesis due to a perceived higher risk of morbidity with surgery. However, most studies have used an arbitrary age cut-off to define "elderly" and this research has yielded conflicting results.

Purpose: The purpose of this study was to investigate the impact of frailty on morbidity after surgery for degenerative lumbar spondylolisthesis treated with a posterior approach. Read More

Minimally Invasive Posterior Cervical Discectomy: 2-Dimensional Operative Video.

Oper Neurosurg (Hagerstown) 2021 Sep 8. Epub 2021 Sep 8.

Department of Neurosurgery, Henry Ford Hospital, Detroit, Michigan, USA.

Minimally invasive posterior cervical microdiscectomy is an appropriate surgical approach for patients with foraminal stenosis from herniated disc with radicular symptoms that is not responsive to conservative management. While anterior cervical discectomy and fusion (ACDF) or arthroplasty is increasingly utilized to treat herniated disc, a posterior approach eliminates the risk of potential approach related injuries to the esophagus, carotid artery, or recurrent laryngeal nerve. Additional benefits of posterior decompression include avoidance of instrumentation, which represents an increased healthcare cost, as well as potential long-term risks of adjacent-level pathologies or device failures.

Transmastoid exposure of the labyrinthine segment of the facial nerve: an anatomical study.

Braz J Otorhinolaryngol 2021 Aug 11. Epub 2021 Aug 11.

Koc University, Faculty of Medicine, Department of Anatomy, Istanbul, Turkey.

Introduction: Compression of the labyrinthine segment of the facial nerve by edema has been considered as an important pathology in the majority of the cases of idiopathic facial nerve paralysis. Hence, it is suggested that total decompression of the facial nerve should also include the labyrinthine segment by a middle fossa approach. However, the middle fossa approach requires craniotomy and temporal lobe retraction, which increases the morbidity. Read More
