Impact of Pregnancy on Loss of Deformity Correction After Pedicle Screw Instrumentation for Adolescent Idiopathic Scoliosis

Curve Progression and Clinical Outcomes in Pregnant Females with Adolescent Idiopathic Scoliosis: A Systematic Review and Meta-Analysis

BACKGROUND

Prior reviews investigating the impact of pregnancy on adolescent idiopathic scoliosis (AIS) have reached different conclusions and a meta-analysis of curve progression among pregnant females with AIS and its effects on clinical outcomes has not previously been performed.

METHODS

A comprehensive search of major bibliographic databases (PubMed, Embase, and Scopus) was conducted for articles pertaining to spinal curve progression during pregnancy among patients with AIS. Patient demographics, scoliotic curve outcomes, and patient-reported quality of life measures were extracted.

RESULTS

Ten studies, including 857 patients with a mean age of 28.7 years, were included. Before pregnancy, 42.1% had undergone spinal fusion and 59.0% had a thoracic curve. Based on prepregnancy and postpregnancy radiographs, the curve increased from 33.9°-38.5°, and meta-analysis revealed a curve progression of 3.6° (range = -5.85 to 1.25, P = 0.003), primarily arising from loss of correction in the unfused group (Unfused = -5.0, P = 0.040; Fused = -3.0, P = 0.070). At the same time, 45.9% patients reported increased low back pain and many reported a negative body self-image and limitations in sexual function. However, 5 studies noted that pregnancy and number of pregnancies were not associated with curve progression, and multiple studies identified similar quality of life-related changes in non-pregnant patients with AIS.

CONCLUSIONS

Among unfused pregnant females with AIS, the spinal curvature increased significantly by 5.0° from before to after pregnancy. However, these changes may be independent of pregnancy status and occur with time. Such curve progression can contribute to a negative body self-image, low back pain, and functional limitations irrespective of pregnancy state.

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.

The impact of pregnancy on women with adolescent idiopathic scoliosis: a scoping review

INTRODUCTION

Adolescent idiopathic scoliosis is the most common spinal deformity encountered in adolescents and larger curves are more prevalent in girls. For females with scoliosis, women's health issues are of particular concern, especially pregnancy. The aim of this review was to summarise the best available evidence to determine the influence of pregnancy on scoliosis-related outcomes in women with scoliosis and whether scoliosis affects maternal-health outcomes, differentiating between patients who have been managed conservatively and/or surgically.

EVIDENCE ACQUISITION

A search was conducted using CINAHL, Scopus, Cochrane Database, MEDLINE, and EMBASE from inception to May 2023 to identify relevant articles in any language. The scoping review followed the PRISMA-ScR guidelines. Studies were eligible if they included pregnant women (primiparous or multiparous) with a diagnosis of scoliosis of unknown aetiology. The results were summarized by outcomes, including pregnancy and scoliosis-related outcomes and type of management.

EVIDENCE SYNTHESIS

Our comprehensive search strategy identified 6872 articles, of which 50 articles were eligible for this review. Back pain appears to be more prevalent in this population during pregnancy and associated with the major curve and the decrease of lumbar lordosis. There have been reports of failed attempted spinal anaesthesia among patients with instrumented scoliosis correction and minor complications related to epidural anaesthesia at a higher rate compared to non-instrumented patients and healthy controls, however successful spinal analgesia can be achieved in patients with instrumented scoliosis correction. Overall, the caesarean section rate was similar in scoliosis patients compared to controls without scoliosis and to national averages. Curve progression occurs in some but not all patients during pregnancy, and this phenomenon occurs irrespective of the treatment received.

CONCLUSIONS

Higher-quality prospective longitudinal research is needed to understand the relationship between pregnancy and adolescent idiopathic scoliosis. Further, the patient's perspective, concerns and fears surrounding pregnancy with scoliosis are yet to be explored. Exploring the impact of pregnancy on women with adolescent idiopathic scoliosis would have clinically relevant outcomes and could help provide pertinent answers to patients and healthcare workers and help guide future research.

The Efficacy of a Posterior Approach to Surgical Correction for Neglected Idiopathic Scoliosis: A Comparative Analysis According to Health-Related Quality of Life, Pulmonary Function, Back Pain and Sexual Function

BACKGROUND

This study aimed to evaluate the treatment outcomes of severe idiopathic scoliosis (IS) and hypothesized that surgical treatment would have a superior impact on the health-related quality of life (HRQoL), pulmonary function (PF), back pain, and sexual function.

METHODS

We retrospectively reviewed 195 consecutive patients with IS classified into severe (SG) and moderate groups (MG) with a minimum follow-up of two years.

RESULTS

The mean preoperative curve was 131° and 60° in the SG and MG, respectively. The mean preoperative flexibility in the bending films averaged between 22% in the SG and 41% in the MG. After definitive surgery, the main curve was corrected to 61° and 18° in the SG and MG, respectively. The mean preoperative thoracic kyphosis was 83° in the SG and 25° in the MG, which was corrected to 35° in the SG and 25° in the MG. At baseline, the percentage of predicted lung volume (FVC) was significantly lower in the SG than that in the MG (51.2% vs. 83%). The baseline percentage of the predicted FEV1 values was also significantly lower in the SG than in the MG (60.8% vs. 77%). During the two-year follow-up, the percentage of predicted FVC showed significant improvement in the SG (69.9%) (p < 0.001), and the percentage of predicted FEV1 values during the follow-up improved significantly in the SG (76.9%) (p < 0.001) compared with the MG (81%), with no statistical difference observed during the two-year follow-up. The SRS-22r showed a clinically and statistically significant improvement in the preoperative results to those of the final follow-up (p < 0.001).

CONCLUSIONS

Surgical treatment of severe scoliosis can be safe. It provided a mean correction of the deformity for 59% of patients and significantly improved respiratory function, with the percentage of predicted forced expiratory volume in 1 s improving by 60% and the forced vital capacity improving by 50%, resulting in clinically and statistically significant improvements in the SRS-22r, HRQoL outcome scores, and back pain (reduced from 36% to 8%), as well as improved sexual function. The planned surgical treatment can achieve a very significant deformity correction with a minimal risk of complications. The surgical treatment has a superior impact on the quality of life patients with severe spinal deformities and significantly improves function in every sphere of life.

Unusual cause of hemoptysis: A case report

Hemoptysis is defined as bleeding from the lower respiratory tract. It can be life-threatening and requires urgent investigation and intervention. Common causes of hemoptysis include bronchiectasis, tuberculosis, aspergilomas and malignancy. We present an unusual case of hemoptysis in a young woman with a history of surgery for scoliosis 18 years earlier. A 30-years-old woman was admitted to our institution for recurring hemoptysis since one year. She had a history of scoliosis and had undergone antero-lateral Th7 through Th12 spinal fusion surgery 18 years earlier. The hemoptysis was slight and resolved spontaneously or after empirical antibiotic therapy, and was attributed to bronchitis. Computed tomography revealed spinal rod penetration into the lung resulting in injury, while the caudal edge of the rod migrated into the liver and the joining screws had entered the mediastinum. Hemoptysis was due to penetration of the rod into the lung. The patient underwent extensive surgery, which was successful. The case highlights the need for thorough evaluation of patients with hemoptysis. Every incident of hemoptysis, even if minor, should be promptly investigated, because it can be life-threatening.
