Background: The traction mattress is a noninvasive gadget for treating decrease again ache attributable to herniated intervertebral discs. On this examine, we investigated the affect of the traction mattress on the decrease again as a way of accelerating the disc peak and creating a niche between aspect joints.
Strategies: Computed tomography (CT) photos have been obtained from a feminine volunteer and a three-dimensional (3D) mannequin was created utilizing software program package deal MIMICs 17.zero. Afterwards, the 3D mannequin was analyzed in an analytical software program (Abaqus 6.14). The examine was performed underneath the next traction masses: 25%, 45%, 55%, and 85% of the entire physique weight in several angles.
Outcomes: Outcomes indicated that the loading angle within the L3-Four space had 36.eight%, 57.Four%, 55.32%, 49.eight%, and 52.15% impact on the anterior longitudinal ligament, posterior longitudinal ligament, intertransverse ligament, interspinous ligament, and supraspinous ligament, respectively. The respective values for the L4-5 space have been 32.three%, 10.6%, 53.Four%, 56.58%, and 57.35%. Additionally, the physique weight had 63.2%, 42.6%, 44.68%, 50.2%, and 47.85% impact on the anterior longitudinal ligament, posterior longitudinal ligament, intertransverse ligament, interspinous ligament, and supraspinous ligament, respectively. The respective values for the L4-5 space have been 67.7%, 89.Four%, 46.6%, 43.42% and 42.65%. The authenticity of outcomes was checked by evaluating with the experimental information.
Conclusions: The outcomes present that traction beds are extremely efficient for disc motion and decrease again ache reduction. Additionally, an optimum angle for traction might be obtained in a 3D mannequin evaluation utilizing CT or magnetic resonance imaging photos. The optimum angle can be totally different for various sufferers and thus ought to be decided based mostly on the decreased peak of the intervertebral disc, weight and peak of sufferers.
