Summary: This study used magnetic resonance imaging to observe the changes in lumbar nerve roots and psoas muscle during lumbar intervertebral disc surgery. The results showed that the prone position did not affect the lumbar nerve roots, psoas morphology, and great vessel position compared to the supine position.

Summary: Intraoperative femoral nerve monitoring can provide timely alerts to surgeons about the degradation of femoral nerve function, and prompt surgical countermeasures can mitigate or avoid nerve injuries. However, the common strategy of limiting retraction duration may not be effective.

Summary: The retrospective case review presented an anatomic approach to transpsoas interbody fusion without psoas stimulated electromyography (sEMG) and evaluated the rate of neurological and approach-related complications. The study showed that the anatomic transpsoas approach demonstrated a rate of complications comparable or superior to the traditional transpsoas approach with sEMG.

Summary: The purpose of this study was to investigate the occurrence and risk factors of lumbar plexus injury (LPI) after oblique lumbar interbody fusion (OLIF) surgery. The study found that narrow OLIF channel space and the anterior edge of left psoas major muscle overpassing the anterior edge of surgical intervertebral disc (IVD) were significant risk factors for OLIF surgery-related LPI.

Summary: This retrospective study reported the surgical technique and clinic-radiological outcomes of endoscopic anterior to psoas interbody lumbar fusion. The results showed that this technique achieved satisfactory results in treating lumbar instability associated with disc herniations and foraminal stenosis.

Summary: This article presents a modified technique for oblique lateral lumbar interbody fusion (OLIF) called the anteroinferior psoas (AIP) technique, aiming to improve security during surgery. By adjusting the incision location and using custom retractors, the technique offers a short learning curve, satisfactory clinical outcomes, and low risk of perioperative complications.

Summary: The study aimed to investigate the incidence and clinical characteristics of lumbar sympathetic trunk (LST) injury after oblique lumbar interbody fusion (OLIF). The results showed that 16 patients (29.6%) were diagnosed with LST injury after surgery, and the difference in skin temperature between the two legs lasted for 1.5 to 12 months. Most patients with LST injury experienced moderate discomfort. The incidence of LST injury was higher in patients with multi-segment OLIF than in those with single-segment OLIF.

Summary: This study presents a systematic anatomical description of the neuroanatomical features and spatial orientation within the psoas major. The study identifies safe zones in the area between the anterior and posterior edges of the vertebral body and determines the specific locations of nerve exit points at different intervertebral disc levels. This information is crucial for spine surgeons to plan surgeries and reduce the risk of nerve injury.

Summary: This is the first comprehensive study on the position of the lumbar plexus in lateral lumbar interbody fusion (LLIF), and it was found that the lumbar plexus is significantly displaced ventrally with the supine position compared to lateral decubitus position, and MRI may overestimate ventral encroachment of lumbar plexus.

Summary: Osteoporotic vertebral compression fractures (VCFs) are common and usually stable injuries in elderly patients, but they can lead to neurological deterioration due to canal invasion. Liver cirrhosis (LC) and its complications increase the risk of bleeding, which can contribute to increased morbidity and mortality. We present the first reported case of lumbar plexus palsy caused by a liver-cirrhosis-related massive psoas hematoma and a stable VCF after minor trauma. This case highlights the potential severe neurological deficits associated with seemingly trivial injuries and discusses possible pathophysiological mechanisms.

Summary: This study investigated the surgical outcomes and prognostic factors of anterior lumbar interbody fusion (ALIF) in revision lumbar interbody fusion. The results showed that ALIF achieved positive clinical and radiographic results in revision lumbar fusion surgery. However, having two or more preoperative fusion segments negatively impacted back pain improvement reaching the minimum clinically important difference (MCID).

Summary: This is a retrospective study that demonstrates a modified oblique lumbar interbody fusion technique. The modified technique allows for easy exposure of the lumbar spine under direct microscopic vision, resulting in less psoas weakness and neurovascular injury.

Summary: This study aimed to investigate quantitative changes in psoas and paraspinal muscle morphology that occur on index levels after SA-LLIF. The results showed that SA-LLIF did not alter psoas muscle morphology, highlighting its minimally invasive nature. However, the percentage of fat infiltration of paraspinal muscles significantly increased over time, suggesting a pain-mediated response and/or the result of segmental immobilization.

Summary: This study aimed to evaluate the predictive role of saphenous somatosensory-evoked potentials (saphSSEP) monitoring on femoral nerve health during lumbar interbody fusion (LIF) procedures. The results demonstrated that saphSSEP monitoring was reliable in most cases and provided highly predictive feedback on neurological events.

Summary: This study evaluated the efficacy and safety of using a modified lateral approach for oblique lateral interbody fusion (OLIF) in treating lumbar degenerative diseases. The surgical time and blood loss were minimal, with significant improvements in postoperative pain and disability scores for patients. Most complications were transient and the overall safety profile was good.
