Background: The traction mattress is a noninvasive machine for treating decrease again ache brought on by 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 spot between side joints.
Strategies: Computed tomography (CT) pictures had 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 carried out beneath the next traction hundreds: 25%, 45%, 55%, and 85% of the entire physique weight in numerous 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 had 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 had 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 aid. Additionally, an optimum angle for traction might be obtained in a 3D mannequin evaluation utilizing CT or magnetic resonance imaging pictures. The optimum angle could be totally different for various sufferers and thus needs to be decided primarily based on the decreased peak of the intervertebral disc, weight and peak of sufferers.
