To investigate the relationship between the axial rotation of the unfused lumbar spine and the parameters of the instrumented thoracic spine at varying time points after selective thoracic fusion (STF) in Lenke 1B and 1C adolescent idiopathic scoliosis (AIS). Retrospective analysis of the prospectively collected data. Moreover, the tensile pre-strained cells may further be utilized in either cell therapy to treat mild disc degeneration disease, or the development of a disc construct for total disc replacement. Knowledge on the effects of tensile pre-strain exposure is necessary to optimize AF development for tissue reconstruction. Our results demonstrated the regenerative ability of AF cell pellets subjected to 24 h tensile pre-straining. Investigation on cellular proliferation, phenotypic gene expression, and histological changes revealed that tensile pre-strain for 24 h had significant and lasting effect on the AF tissue development, with enhanced cell proliferation, and up-regulation of collagen type I, II, and aggrecan expression. Equibiaxial cyclic tensile strain was applied on AF monolayer cells over a period of 24 h, which was subsequently developed into a cell pellet. This study aims to investigate the effect of tensile pre-strained exposure of 1 to 24 h on the development of AF pellet culture for 3 weeks. Till to date, the application and effect of tensile pre-strained cells to construct a three-dimensional (3D) AF tissue remains unknown.

Although mechanical strain can produce either catabolic or anabolic consequences to the cell monolayer, little is known on how to translate these findings into further tissue engineering applications. Prior research has investigated the immediate response after application of tensile strain on annulus fibrosus (AF) cells for the past decade. More than half of the participants had osteopenia or osteoporosis, and both preoperative and postoperative low BMI were risk factors for osteopenia in adulthood. Moreover, body weight at survey (Spearman rank correlation coefficient, r S = 0.49), as well as BMI at both surgery ( r S = 0.67) and survey ( r S = 0.61) demonstrated positive correlations with the Z-score (p <. 23.2) were significantly lower in group P than in group N (p <. 56.8) and mean body mass index (BMI) at both surgery (17.2 vs. Mean body weight (kg) at survey (46.6 vs. Z scores of the left hip were used for analyses of the association between bone mineral status and individual factors.Įleven participants (52.4%) were categorized into group P. Based on their T scores for bone mineral density (BMD) of the left hip, participants were divided into an osteopenia/osteoporosis group (group P, T score < −1.0) and a normal group (group N, T score ≥ −1.0). Twenty-one (19 women mean age, 45.3 years) of 45 consecutive patients with AIS who underwent spinal instrumented fusion surgery between 19 consented to inclusion in the current analysis.

However, the long-term results of AIS surgery on BMD have not been evaluated. Surgically treated AIS patients may be likely to have osteopenia in adulthood because the association between AIS and osteopenia has been well documented. We investigated the incidence and risk factors for osteopenia at a minimum of 20 years after spinal instrumented fusion for adolescent idiopathic scoliosis (AIS).

This approach may constitute a good compromise between complete vertebral excision and simple in situ fusion to correct spinal deformities associated with lumbar hemivertebra in adult patients. The combined approach with TPO corrected the lumbar kyphosis and achieved fusion. In their series, Mohanty and Kumar (13) noted that the lumbar region was involved in only 8% of cases.īy definition, hemivertebra is a wedge-shaped vertebra (1, 10, 12) Conclusions McMaster and Ohtsuka (11) observed that the thoracic region was the most common site for congenital scoliosis. Most documented cases of congenital scoliosis involve pediatric patients (1, 2, 3, 4, 5, 7, 10). Statistically, male-to-female frequency of congenital scoliosis is 1:1.3 and of right to left curve is 1.4:1 (10, 12, 13). She had a visual analogue scale score of 8 out of 10 for back pain and 6 out of 10 for radicular pain. She also complained of L5 sciatica of 6 months' duration, for which she had undergone medical treatment and several epidural corticosteroid injections that were unsuccessful. The pain was located in the lumbar area with typical features of discogenic pain. A 46-year-old woman presented in January 2009 with a complaint of severe chronic low back pain of 6 years' duration.
