“…While playing an important role in the physiological function of the lumbar spine, facet joints also carry 6%–30% of the axial compressive load ( Yin et al, 2020 ). This loading may also accelerate the degeneration of the facet joint, especially in people over 60 years of age ( Yin et al, 2020 ). Such degeneration usually begins with changes in the articular cartilage and eventually leads to destruction of the entire joint and tissues.…”

Objective: The purpose of this study was to analyze the stability and instrument-related complications associated with fixation of the lumbar spine using the Short-Rod (SR) technique.Methods: Using finite element analysis, this study assessed the stability of a bilateral lumbar fixation system when inserting the pedicle screws at angles of 10°, 15°, and 20° to the endplate in the sagittal plane. Using the most stable construct with a screw angle, the model was then assessed with different rod lengths of 25, 30, 35, and 45 mm. The optimal screw inclination angle and rod length were incorporated into the SR model and compared against traditional parallel screw insertion (pedicle screws in parallel to the endplate, PPS) in terms of the stability and risk of instrument-related complications. The following parameters were evaluated using the validated L4–L5 lumbar finite element model: axial stiffness, range of motion (ROM), stress on the endplate and facet joint, von-Mises stress on the contact surface between the screw and rod (CSSR), and screw displacement.Results: The results showed that the SR model with a 15° screw inclination angle and 35 mm rod length was superior in terms of construct stability and risk of complications. Compared to the PPS model, the SR model had lower stiffness, lower ROM, less screw displacement, and lower stress on the facet cartilage, the CSSR, and screws. However, the SR model also suffered more stress on the endplate in flexion and lateral bending.Conclusion: The SR technique with a 15° screw inclination and 35 mm rod length offers good lumbar stability with a low risk of instrument-related complications.

“…However, if osteoarthritis occurs, the joint load of abnormal joint force can be as high as 47% [ 21 ], which also increases the risk of low back pain. Yin et al [ 16 ] found that with the increase in facet degeneration, the initial increase in lumbar range of motion decreased, which would change the stability of the lumbar spine. Therefore, it is very important to delay facet degeneration.…”

“…In terms of LFJs, Li and his colleagues [ 15 ] were the first to use this technique to quantify the in vivo kinematics of lumbar facets in nonfunctional weight-bearing positions. Yin [ 16 ] also studied the effect of degenerative facets on the range of motion of the lumbar spine through this system. Although these studies have greatly analyzed the kinematics of LFJs in vivo under functional loading, their research direction is limited to either non-weight bearing or flexion and extension.…”

Background Lumbar facet joints (LFJs) are usually related to the pathogenesis of the spine. The purpose of this paper is to study the effects of lifting load on the motion of lower lumbar facet joints in vivo. Methods Ten healthy volunteers aged 25 ≤ 39 years, 5 males and 5 females, were recruited. Using a dual fluoroscopy imaging system (DFIS) combined with CT, firstly, the L3-S1 segment image scanned by CT was converted into a three-dimensional model. Then, the lumbar motion images of L3-S1 vertebrae taken by the DFIS under different loads (0 kg, 5 kg, 10 kg) and different body postures (maximum flexion and extension, maximum left and right bending, and maximum left and right torsion) were captured. Finally, in the Rhino software, the instantaneous motion state of the lumbar spine is reproduced by translation and rotation according to the anatomical structure of the lumbar spine and the previous images. With the help of computer software, a Cartesian coordinate system was placed in the center of each articular surface to measure the kinematics of the articular process and to obtain 6DOF data under different loads (0 kg, 5 kg, 10 kg) in the lumbar facet joints. Results In the flexion and extension of the trunk, weight bearing reduced the translational range in the mid-lateral direction. In the L3/4 segment, the lateral translational range of the left and right facet joints gradually decreased with increasing load, and the translational range at 0 kg was significantly greater than that at 10 kg (left side: 0 kg, 0.86° ± 0.57°, 10 kg, 0.24° ± 0.26°, p = 0.01; right side: 0 kg, 0.86° ± 0.59°, 10 kg, 0.26° ± 0.27°, p = 0.01). In the L5/S1 segment, the translation range of the LFJ at 0 kg was significantly greater than that at 10 kg (p = 0.02). Other bending and rotation movements were not found to cause differential changes in the 6DOF of the LFJ. In bending, the rotation range was the largest in the L3/4 segment (p < 0.05) and gradually decreased from top to bottom. At the same level, there were significant differences in the translation range of the left and right facets in the anterior posterior and craniocaudal directions (p < 0.05). Conclusion Increasing the load has a significant impact on the coupled translational movement of lumbar facet joints. The asymmetric translational movement of the left and right facet joints may be a factor that accelerates the degeneration of facet joints.

“…About 20% of people detoriation of the facet joints. 6 The probability of wear and tear of disc usually increase with age and may not give rise to any symptoms, but with progression it can cause severe LBP. 7 A comprehensive clinical history and physical examination can usually diagnose severity of illness that may be resulting in back pain.…”

Objective: To compare the clinical features of lower backache with Magnetic Resonance Imaging (MRI) findings on gender basis. Study design & Setting: A cross-sectional descriptive study was carried out among male & female patients with a backache at Sir Syed Hospital, Karachi. This study conducted from 1st Jan 2020 to 1st June 2020. We studied 90 patients by using the non-probability convenient sampling technique. Methodology: Lower backache is a common problem that creates disability. MRI lumbar spine without contrast were reviewed with clinical complaints. Performa was used after the ethical approval from Institutional Research and Ethical committee. Components focused during the study in MRI findings at different spinal levels were disc bulging, neural foraminal compromise, nerve root compression, ligamentum flavum and facet joint hypertrophy. Results: The results showed that the mean age of 90 patients was 44.64 years. On MRI imaging 46(86.8%) males and 26(70.3%) females had disc desiccation but multi-level disc osteophyte complexes were demonstrated more in females 11(29.7%). Diffuse disc bulge is more in males at L4-5 and L5-S1 level 49(92.5%) than in females 34(91.9%) at L4-5 and 33(89.2%) at L5-S1 level with mild to moderate spinal canal stenosis. The narrowing of Neural foramen is almost similar at L4-5 level in both gender but more at L5-S1 in females 35(94.6%) as compared to males 49(92.5%) with nerve root compression. Overall male patients tended to have slightly more disc degenerative changes than females. Conclusion: Lower Lumbar disc disease is a common problem showing significant disc space narrowing and bulges slightly more in our male population than females.
