Health-related quality of life of adult, non-surgically treated patients with idiopathic scoliosis and curves above 45°: a cross-sectional study at an average follow-up of 30 years

From Rib Hump to Baby Hump-Common Questions of Patients Suffering from and Undergoing Treatment for Scoliosis-A Comprehensive Literature Review

Background: Scoliosis, the most prevalent spinal deformity in children, is often associated with adolescent idiopathic scoliosis (AIS). Curves surpassing 50 degrees can deteriorate, especially thoracic curves, leading to pulmonary limitations. Surgical intervention is usually advised for curvatures exceeding 50 degrees to halt further progression. Severe AIS is notably more frequent in females, yet knowledge regarding subsequent pregnancies and associated risks is scarce. Female patients often inquire about conception, pregnancy, labor, and future back pain (BP) concerns. Reports on the long-term outcomes after pediatric AIS treatment and pregnancy consequences remain limited. Uncertainty looms over the likelihood of increased back pain (BP), cesarean sections (CSs), or other pregnancy-related issues following surgical AIS management. In this investigation, an attempt was made to scrutinize the existing research on individuals afflicted with scoliosis who received either conservative or surgical treatment, with the aim of delineating crucial and pragmatic findings that can serve as a compass for spine surgeons when counseling young patients with adolescent idiopathic scoliosis regarding the ailment, its repercussions, the available treatment modalities, and the associated outcomes. A comprehensive analysis pinpointed the optimal data at hand. Consequently, the primary objective of this investigation was to assess the patient-reported and clinical consequences in scoliosis patients who have undergone segmental posterior fusion and subsequently conceived. Conclusions: While the majority of individuals with AIS are capable of conceiving and bearing children, they may encounter greater challenges in fertility than healthy women unaffected by AIS. Pregnant women with a prior history of spinal fusion for AIS can undergo pregnancy and childbirth with no significant escalation in perinatal complications. Women who have undergone surgical procedures for AIS have been observed to exhibit a prevalence of back pain comparable with that of healthy pregnant women; however, a higher incidence of low back pain is evident when spinal fusion is extended to the L3 or L4 vertebra. Although back pain is a common occurrence in pregnant women with AIS, the spinal alterations induced by pregnancy are typically minor and transient. In comparison with healthy women, individuals with a history of spinal fusion necessitate cesarean sections more frequently. The degree of correction loss during pregnancy is lower in previous reports involving pedicle screw instrumentation than in previous reports involving Harrington or hybrid segmental instrumentation.

Incidence of back pain from initial presentation to 3 years of follow-up in subjects with untreated adolescent idiopathic scoliosis

BACKGROUND

Although back pain may be present in subjects with adolescent idiopathic scoliosis (AIS), its natural history is unknown. Therefore, this study evaluated the incidence of back pain in scoliotic adolescents longitudinally.

METHODS

This retrospective analysis examined prospectively collected pain subscale data of the Scoliosis Research Society questionnaire between the initial presentation and up to 3 years of follow-up. Consecutive subjects with AIS aged 10-18 at baseline managed by observation within the study period were included. Study subjects with at least one time point of follow-up data were considered. Alternatively, a group with physiotherapy-treated was also included for comparison.

RESULTS

We enrolled 428 subjects under observation. The incidence of back pain among study subjects was 14.7%, 18.8%, and 19.0% for the first year, second year, and third year of follow-up, respectively. Most experienced mild pain (1 out of 5 points) throughout the study. Neither incidence nor intensity of pain significantly differed between subjects under observation and received physiotherapy. Additionally, study subjects with a new onset of back pain had poorer function, self-image, and mental health scores than those without pain.

CONCLUSION

We investigated the incidence of back pain longitudinally in subjects suffering from AIS. Further validation of the current results is warranted.

The effects of back extensor strength in different body positions on health-related quality of life in patients with degenerative spinal deformity

BACKGROUND

Degenerative spinal deformity (DSD) is believed to originate from degeneration of the discs and facet joints and vertebral wedging. Currently, the nosogeny of DSD is not yet fully clarified and there has been no systematic study on the impact of their lower back muscle strength on quality of life.

OBJECTIVE

To determine the characteristics of back extensor strength (BES) in different body positions and examine their correlations with health-related quality of life (HQOL) in degenerative spinal deformity (DSD) patients.

METHODS

Participants comprised 60 DSD patients and 40 healthy volunteers. Maximal isometric BES was evaluated by dynamometers with the subject in three different positions (standing, prone, sitting). The visual analogue scale (VAS) score, Oswestry Disability Index (ODI), Roland-Morris Disability Questionnaire (RMQ), and 36-item Short Form Health Survey (SF-36) score were used to evaluate patient HQOL. Correlations between the BES in different body positions and HQOL were analysed.

RESULTS

The BES values in three body positions were significantly smaller in DSD patients than healthy subjects (P< 0.05). The standing BES was found to be negatively associated with ODI and RMQ (R= 0.313, p< 0.05 and R= 0.422, p< 0.01, respectively). A negative relationship between sitting BES and RMQ was also seen (R= 0.271, p< 0.05). In addition, the standing and prone BES were positively correlated with the physical functioning score of the SF-36 (R= 0.471, p< 0.01 and R= 0.289, p< 0.05, respectively), and the sitting BES was positively correlated with the role-physical score of the SF-36 (R= 0.436, p< 0.01).

CONCLUSION

The results indicate that the back extensor muscle is compromised in DSD patients and there are differences in predicting the severity of disability and physical HQOL scores with BES in different positions. Standing BES was the most reliable contributor to HQOL among three body positions.
