Summary: The presence of intravertebral cleft (IVC) in patients undergoing percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fractures (OVCFs) was associated with a lower incidence of leakage through veins, but a higher incidence of leakage through the cortex, with no significant effect on the occurrence of general leakage.

Summary: This study compared the safety and clinical efficacy of PVP and PKP in treating KD, finding no significant differences in intraoperative blood loss and bone cement leakage between the two groups. PKP had significantly longer surgical time, higher operation costs, and more fluoroscopy times compared to PVP. Both procedures significantly improved pain and vertebral deformity, with PKP showing better results in height and kyphosis correction.

Summary: In patients with Kummell's disease treated by percutaneous vertebroplasty, those with bone cement leakage had longer disease course, older age, more severe kyphotic deformity, vertebral compression, and osteoporosis. However, there were no significant differences in the rate of adjacent vertebral refractures, visual analogue scale, and Oswestry dysfunction index between the leakage group and non-leakage group, indicating that bone cement leakage does not affect the surgical outcomes.

Summary: This retrospective cohort study analyzed the clinical and radiological effects of type 2 diabetes mellitus on the prognosis of osteoporotic vertebral compression fracture after percutaneous vertebroplasty. The study found that the vertebral body morphology of type 2 diabetes mellitus patients deteriorated since the sixth month after surgery. Osteoporotic fracture classification provided a good prognostic reference value for both the control and the type 2 diabetes mellitus population.

Summary: This study comparatively analyzed the clinical and radiographic outcomes of percutaneous kyphoplasty in patients with severe osteoporotic vertebral compression fractures with or without intravertebral cleft. The study found that the group without intravertebral cleft showed better clinical outcomes and could maintain spinal sagittal balance better than the group with intravertebral cleft during long-term follow-up.

Summary: This retrospective study analyzed 109 eligible OVCF patients and found an intradiscal leakage rate of 32.1% during PKP treatment. Compression rate and cemented vertebral body fraction were identified as independent risk factors for intradiscal leakage. A well-calibrated predictive nomogram was established to accurately predict the probability of intradiscal leakage with good predictive power and fitness of data.

Summary: This study investigated the biomechanical stress on sandwich vertebrae and common adjacent vertebrae in different levels of spinal mobility. Results showed that sandwich vertebrae did not always experience the highest stress, and the most stressed vertebrae varied with the degree of spinal curvature. Therefore, patients should avoid prolonged spinal curvature and consider wearing spinal braces for protection after surgery to prevent long-term overload and potential fractures.

Summary: This study investigated whether pre-injecting a composite of bone cement and gelatine sponge before injecting bone cement during PVP can lower the leakage rate in stage I and II Kummell's disease. The results showed that the group using the bone cement-gelatine sponge composite had a significantly lower incidence of bone cement leakage compared to the group not using the composite. Additionally, this technique can relieve pain and improve vertebral body height.

Summary: This study discussed the effect of balloon dilatation mode on percutaneous kyphoplasty in the treatment of osteoporotic vertebral fractures with intravertebral cleft. It was found that double balloon bilateral dilatation technique can better restore the injured vertebral height, while the single balloon bilateral alternating dilatation technique is more likely to be inserted and filled, leading to better long-term analgesia and lumbar function of patients.

Summary: The study evaluated the readability of scout images for extraspinal organs in lumbar spine MRI with different protocols, finding a significant difference in readability according to the image protocols. Two radiologists independently reviewed the scout images and identified that over 50% of femoral heads could be categorised as definitely or possibly readable.

Summary: This study evaluated the use of MAVRIC SL STIR technique for metallic artifact reduction in MRI of postoperative cervical spine with artificial disk replacement. The results showed that this technique can reduce signal void areas and distortion, leading to better visualization of anatomy. However, it should be used in combination with STIR for evaluating the image quality of the spinal cord.

Summary: The study demonstrated that 80% of patients with nontraumatic intracranial SDH had spinal CSF leaks, with those under the age of 69 being more susceptible. It is recommended for patients in this age group to undergo CT myelography for evaluation. Patients aged 69 and older are also at risk for SIH-induced SDH and may benefit from CT myelography for diagnosis.

Summary: Background Dual-layer spectral detector computed tomography (DLCT) has the potential to enhance CT arthrography through improved image quality and analysis of tissue composition. The objective of this study was to evaluate the image quality of monoenergetic reconstructions from DLCT arthrography of the shoulder and assess their additional diagnostic value in differentiating calcium from iodine. The results showed that DLCT had no additive value in differentiating calcium from iodine in small, hyperattenuating lesions in the labrum and tendons.

Summary: Spine intervention, particularly epidural steroid injection (ESI), is a significant treatment option for spinal pain. However, controversies remain regarding its efficacy, and serious complications are rare. This article reviews the indications, compares techniques, and provides practical tips for ESI procedures. Combining radiologists' anatomical knowledge with image-guided interventions, ESI is expected to thrive in the expanding field of spine intervention.

Summary: Magnetic resonance imaging (MRI) is the standard imaging technique for diagnosing spinal stenosis, a prevalent degenerative disorder in the elderly. Standardized interpretation of spinal MRI is necessary for accurate communication with clinicians and conducting research. This review focuses on the Lee grading system, which is based on the pathophysiology and radiologic findings of central canal and neural foraminal stenosis in the cervical and lumbar spine.

Summary: This study compared the coronal plane with the axial and sagittal planes in opportunistic screening of osteoporosis using CT. The results showed that the coronal plane did not significantly differ from the axial and sagittal planes in diagnosing osteoporosis. Therefore, the coronal plane, as well as the axial and sagittal planes, can be used interchangeably in measuring bone mineral density using CT.
