[38,39] In a number of studies undertaken by Taylor et al, [29,31,32,41] including the study by Konz et al, [44] the authors utilised a smaller 3D cluster that could be applied to the back surface of the participants using double-sided adhesive tape.

“…While Konz et al [44] attached a rubber base plate over L3, 15 studies applied the 3D cluster over the spinous process at the level of T12/L1. The number of markers that formed the cluster varied between three [30,33,38,40,42,44] and four. [29,[34][35][36][37] Although some of the studies included in the review were follow-up investigations, only one study provided sufficient information that detailed the structural design of the 3D cluster.…”

We evaluated the gait characteristics of patients who had short or long-segment fusion after thoracolumbar burst fractures. The study included 12 patients (5 male, 7 female) who had vertebral fusion after traumatic thoracolumbar region (T12-L2) burst fractures. Patients were divided into two groups based on fixation type (short or long segment). Twelve healthy age and sex-matched subjects (seven male, five female) served as controls. Quantitative gait data, including all time-distance (walking velocity, cadence, step time, step length, double support time), kinematic (joint rotation angles of pelvis, hip, knee, and ankle), and kinetic data (moments of hip in sagittal and coronal plane) were collected. Three patients had a T12, six patients an L1, and three patients had an L2 lesion. Patients in the two groups were similar in terms of age, sex, and time since operation. No significant differences were found in the time-distance, kinematic, and kinetic gait characteristics between the two groups. This preliminary study reveals that the gait characteristics of patients with short and long-segment fusion after thoracolumbar burst fractures were similar to those of healthy subjects and did not differ from each other. However, the present results should be interpreted with caution due to the small sample size. Future studies with larger groups are needed to provide additional data to validate these findings. ß

Animal models have historically provided an appropriate benchmark for understanding human pathology, treatment, and healing, but few animals are known to naturally develop intervertebral disc degeneration. The study of degenerative disc disease and its treatment would greatly benefit from a more comprehensive, and comparable animal model. Alpacas have recently been presented as a potential large animal model of intervertebral disc degeneration due to similarities in spinal posture, disc size, biomechanical flexibility, and natural disc pathology. This research further investigated alpacas by determining the prevalence of intervertebral disc degeneration among an aging alpaca population. Twenty healthy female alpacas comprised two age subgroups (5 young: 2-6 years; and 15 older: 10þ years) and were rated according to the Pfirrmann-grade for degeneration of the cervical intervertebral discs. Incidence rates of degeneration showed strong correlations with age and spinal level: younger alpacas were nearly immune to developing disc degeneration, and in older animals, disc degeneration had an increased incidence rate and severity at lower cervical levels. Advanced disc degeneration was present in at least one of the cervical intervertebral discs of 47% of the older alpacas, and it was most common at the two lowest cervical intervertebral discs. The prevalence of intervertebral disc degeneration encourages further investigation and application of the lower cervical spine of alpacas and similar camelids as a large animal model of intervertebral disc degeneration.
