The Effect of Cannabinoids on Single-level Lumbar Arthrodesis Outcomes in a Rat Model
The opioid epidemic is a public health crisis affecting spine care and pain management. Medical marijuana is a potential non-opioid analgesic yet to be studied in the surgical setting since its effects on bone healing are not fully understood. Studies have demonstrated analgesic and potentially osteoinductive properties of cannabinoids with endocannabinoid receptor expression in bone tissue. (Source: The Spine Journal)

Accurate placement of thoracolumbar pedicle screws using a handheld iOS-based navigation device: a prospective intra-patient agreement study
Accurate pedicle screw placement is a challenge with reported misplacement rates of 10% and higher. A handheld navigation device (HND) may provide accuracy equal to CT-based navigation (CT-Nav) but without the cost and complexity. (Source: The Spine Journal)

Complications and Outcomes After Three-Column Osteotomy: A 5-Year Follow-up
Three-column spinal osteotomies (3-CO) are powerful techniques used to correct spinal deformity. These surgeries are associated with an elevated risk of complications. While outcomes have been reported in the literature with 2 years follow-up, longer-term outcomes of three-column osteotomies remain understudied. (Source: The Spine Journal)

The biomechanical effect of lumbopelvic distance reduction on reconstruction after total sacrectomy: a comparative finite element analysis of four techniques
The lumbosacral complex serves as a biomechanical keystone, transmitting the forces from the axial skeleton to the lower limbs [1,2]. It plays a crucial role in maintaining an upright posture and enabling the ability to walk [3]. If this anatomical junction is affected by primary malignant sacral tumors [4 –6], surgical interventions invariably emerge as the preferred treatment strategy. However, the surgical treatment of sacral tumors is technically demanding and necessitates careful consideration of anatomical and biomechanical factors [2,7,8]. (Source: The Spine Journal)

Posterior Atlantoaxial Fixation of Osteoporotic Odontoid Fracture: Biomechanical Analysis of the Magerl versus Harms Techniques in a Cadaver Model.
Odontoid fractures are among the most common cervical spine fractures in the elderly and are associated with increased morbidity and mortality. Clinical evidence suggests improved survival and quality of life after operative intervention compared to nonoperative treatment. (Source: The Spine Journal)

Transabdominal Motor Evoked Potential Neuromonitoring of Lumbosacral Spine Surgery
Transcranial Motor Evoked Potentials (TcMEPs) can improve intraoperative detection of femoral plexus and nerve root injury during lumbosacral spine surgery. However, even under ideal conditions, TcMEPs are not completely free of false-positive alerts due to the immobilizing effect of general anesthetics, especially in the proximal musculature. The application of transcutaneous stimulation to activate ventral nerve roots directly at the level of the conus medularis (bypassing the brain and spinal cord) has emerged as a method to potentially monitor the motor component of the femoral plexus and lumbosacral nerves free from t...

Poor postoperative pain control is associated with poor long-term patient-reported outcomes after elective spine surgery: an observational cohort study

S1 vertebral bone quality score independently predicts pedicle screw loosening following surgery in patients with adult degenerative scoliosis
MRI-based vertebral bone quality (VBQ) score is an effective predictor of pedicle screw loosening after lumbar fusion surgery and has been recognized as a valuable tool for assessing preoperative bone quality. Due to the lateral curvature of lumbar spine of degenerative scoliosis, accurate measurement of VBQ score by conventional measurement methods that capture MRI signal intensity at L1-4 may be limited under certain conditions. To this end, a new simplified S1 VBQ score method has been proposed, which is comparable to the previous L1-4 VBQ score or S1 Hounsfield unit (HU) value, and has high accuracy and reliability. (S...

Which patients do we need to consider augmentation of muscle active potentials regarding transcranial electrical stimulation motor-evoked potentials monitoring before spine surgery?
Intraoperative neurophysiological monitoring (IONM) is important to prevent spinal cord or nerve root injuries during spinal surgery. Among the various modalities, transcranial electrical stimulation motor-evoked potentials (Tc-MEPs) have been widely used for IONM to assess motor pathway damage [1,2]. However, the amplitudes of compound muscle action potentials (CMAPs) can be suppressed by anesthetics and neuromuscular blockers [2,3]. Furthermore, patient-related factors such as preoperative motor deficits, age, presence of a lesion in the spinal cord, and endogenous diseases may also affect CMAPs [4 –7].

Pre-operative expectations of patients with Degenerative Cervical Myelopathy: An observational study from the Canadian Spine Outcomes and Research Network
Patients' expectations play a crucial role in the overall success and satisfaction with surgical outcomes. A patient's perception of the anticipated results, recovery process, and potential complications can influence their psychological and emotional well-being throughout their healthcare journey. Patients have a range of expectations, influenced by various factors: personal beliefs, cultural background, and previous medical experiences. Addressing these expectations allows healthcare providers to build trust, mitigate anxiety, and possibly enhance patient compliance with preoperative and postoperative instructions. (Sour...

Advanced MRI metrics improve the prediction of baseline disease severity for individuals with degenerative cervical myelopathy
Degenerative cervical myelopathy (DCM) is the most common form of atraumatic spinal cord injury globally. Degeneration of spinal discs, bony osteophyte growth and ligament pathology results in physical compression of the spinal cord contributing to damage of white matter tracts and grey matter cellular populations. This results in an insidious neurological and functional decline in patients which can lead to paralysis. Magnetic resonance imaging (MRI) confirms the diagnosis of DCM and is a prerequisite to surgical intervention, the only known treatment for this disorder. (Source: The Spine Journal)

Development and Validation of a Radiomics-Based Model for Predicting Osteoporosis in Patients with Lumbar Compression Fractures
Osteoporosis, a metabolic bone disorder, markedly elevates fracture risks, with vertebral compression fractures being predominant. Antiosteoporotic treatments for patients with osteoporotic vertebral compression fractures (OVCF) lessen both the occurrence of subsequent fractures and associated pain. Thus, diagnosing osteoporosis in OVCF patients is vital. (Source: The Spine Journal)
