Minimal-invasive, image guided, 360-degree resection of ilio-lumbo-sacral ostechondroma, planned on the 3D model in a child with hereditary multiple ostechondroma (HMO).

Background: Hereditary Multiple Osteochondromas (HMO), previously known as Multiple Hereditary Exostoses (MHE), is a genetic disorder characterized by the formation of multiple, benign, exostoses (osteochondromas) growing from the metaphyseal region of long bones as well as from the axial skeleton. Lesions originating from the lumbar spine region are rare, and are most common growing from the posterior element of the vertebrae. HMO associated osteochondromas are difficult to treat due to continuous and incontrollable growth of these lesions and a lifetime risk for malignant transformation.

The Spinal Instability Neoplastic Score correlates with epidural spinal cord compression -a retrospective cohort of 256 surgically treated patients with spinal metastases.

Background: Bone metastases can compromise the integrity of the spinal canal and cause epidural spinal cord compression (ESCC). The Spinal Instability Neoplastic Score (SINS) was developed in order to evaluate spinal instability due to a neoplastic process. The SINS has reached wide acceptance among clinicans but its prognostic value is still controversial.

Reliability of thoracolumbar burst fracture classification in the Swedish Fracture Register.

Background: The Swedish Fracture Register (SFR) is a national quality register for all types of fractures in Sweden. Spine fractures have been included since 2015 and are classified using a modified AOSpine classification. The aim of this study was to determine the accuracy of the classification of thoracolumbar burst fractures in the SFR.

Hirayama's disease associated with cervical deformity and spinal cord compression: a case report from Sweden.

Background: Hirayama's disease (HD) is most common in young males, and previous studies are predominantly from Asian countries. The cause of HD is unknown but the most common theory about the pathology speculates on forward bending that causes a compression of the dura mater and the anterior horn of the spinal cord against the vertebra during an overstretch flexion that may result in myelopathy. Both anterior and posterior cervical surgical approaches have been shown to be effective in stopping the disease and improving function; however, HD is also reported to be a self-limited disease, and treatment with a cervical collar may be an alternative for these patients.

Lateral interbody fusion without intraoperative neuromonitoring in addition to posterior instrumented fusion in geriatric patients: A single center consecutive series of 108 surgeries.

Introduction: Lateral lumbar interbody fusion (LLIF) and lateral thoracic interbody fusion (LTIF), supported by intraoperative neuromonitoring (IONM), gained popularity as a mini-invasive alternatives for standard interbody fusion. The objective of this study was to investigate the clinical outcome in a large elderly patient cohort who underwent LTIF/LLIF without IONM.

Methods: This retrospective, single-center study enrolled elderly patients (≥70 years old) operated during the period from 2010 to 2016.

Assessment of Navigated Pedicle Screws From Intraoperative Imaging: A Prospective Study of Accuracy and Agreement.

Background: Intraoperative (IO) image guidance surgery using 3-dimensional fluoroscopic navigation methods, such as the O-arm system, has improved the accuracy of pedicle screw placement in instrumented spine surgery. IO and postoperative (PO) validation of the implant's correct position from radiological images is a decisive step to ensure patient safety and avoidance of complications related to implant misplacement. In this prospective single-center study, the authors investigated the accuracy and agreement of assessment of pedicle screws from IO O-arm images in comparison to PO computed tomography images.

Minimally Invasive Surgery for Thoracolumbar Spinal Fractures in Patients With Ankylosing Spondylitis.

Background: Patients with ankylosing spondylitis (AS) are prone to spinal fractures even after low-energy trauma. Posterior fusion through open surgery has been the standard procedure for spinal fractures in patients with AS. Minimally invasive surgery (MIS) has been proposed as an alternative treatment option.

Using Smartphones for Clinical Assessment in Cervical Spondylotic Myelopathy a Feasibility Study.

Degenerative cervical myelopathy (DCM) is characterized by a progressive deterioration in spinal cord function. Its evaluation requires subjective clinical examination with wide interobserver variability. Objective quantification of spinal cord function remains imprecise, even though validated myelopathy-grading scales have emerged and are now widely used.

Predictive Value of the Spinal Instability Neoplastic Score for Survival and Ambulatory Function After Surgery for Metastatic Spinal Cord Compression in 110 Patients with Prostate Cancer.

Study Design: We retrospectively analyzed Spinal Instability Neoplastic Score (SINS) in 110 patients with prostate cancer operated for metastatic spinal cord compression (MSCC).

Objective: We aimed to investigate the association between SINS and clinical outcomes after surgery for MSCC in patients with prostate cancer.

Summary Of Background Data: The SINS is a useful tool for assessing tumor-related spinal instability, but its prognostic value regarding survival and neurological outcome is still controversial.

Transtubular Anterior Cervical Foraminotomy for the Treatment of Compressive Cervical Radiculopathy: Surgical Results and Complications in a Consecutive Series of Cases.

Study Design: This was a retrospective review of patients with compressive cervical radiculopathy treated with a minimally invasive anterior cervical foraminotomy (ACF).

Purpose: This study aimed to evaluate the results and complication rates of ACF in a consecutive series of patients and to report our clinical results of ACF as a minimally invasive technique in a series of 45 consecutive patients treated for compressive cervical radiculopathy.

Overview Of Literature: ACF is a motion-sparing procedure and an alternative to anterior cervical discectomy and fusion (ACDF) and posterior cervical foraminotomy for direct nerve root decompression in patients with compressive cervical radiculopathy.

Multilevel Pedicular Osteotomies for En Bloc Resection of a Primary Ewing Sarcoma of the Subaxial Cervical Spine with Pedicle Screw Reconstruction.

Background: Primary Ewing sarcoma of the mobile spine is a rare disease. Its management requires careful surgical planning, because radical, margin-free excision is directly correlated with prognosis. Extensive bone removal in the cervical spine can lead to instability and cause postoperative iatrogenic cervical deformity.

Lateral lumbar interbody fusion without intraoperative neuromonitoring: a single-center consecutive series of 157 surgeries.

Objective: Lateral lumbar interbody fusion (LLIF) is frequently used for anterior column stabilization. Many authors have reported that intraoperative neuromonitoring (IONM) of the lumbar plexus nerves is mandatory for this approach. However, even with IONM, the reported motor and sensory deficits are still considerably high.

The Relationship between the Occipitocervical Junction and Thoracic Kyphosis in Ankylosing Spondylitis: A Retrospective Cohort Study of 86 Cervical Fractures in Surgically Treated Patients.

Study Design: Retrospective analysis of prospectively collected data.

Purpose: To describe the radiological characteristics of the occipitocervical area in patients with ankylosing spondylitis (AS) using the novel measure X-angle and to describe the correlation between the ankylosed occipitoatlantoaxial (OAA) joint and thoracic kyphosis (TK).

Overview Of Literature: AS affects the axial skeleton, leading to progressive ankylosis of all vertebral segments.

Does pedicle screw fixation of the subaxial cervical spine provide adequate stabilization in a multilevel vertebral body fracture model? An in vitro biomechanical study.

Background: Cervical vertebral body fractures generally are treated through an anterior-posterior approach. Cervical pedicle screws offer an alternative to circumferential fixation. This biomechanical study quantifies whether cervical pedicle screws alone can restore the stability of a three-column vertebral body fracture, making standard 360° reconstruction unnecessary.
