Optimal days of application of kinesiotaping for the treatment of lumbo-pelvic pain during pregnancy. A systematic review and dose-response meta-analysis

OBJECTIVE

To determine the optimal dose and short-term effectiveness of kinesiotaping (KT) on pain intensity and disability in pregnant women with lumbo-pelvic pain.

DATA SOURCES

MEDLINE (via PubMed Central), CINAHL, Epistemonikos, Scopus, and Web of Science from inception to 21st March 2023.

STUDY SELECTION

We included randomized controlled trials (RCT) conducted on pregnant women with lumbo-pelvic pain treated with KT.

DATA EXTRACTION

The outcomes included pain intensity and disability. ROB-2 and GRADE were used to assess the risk of bias and the certainty of the evidence, respectively. A random effects meta-analysis was performed using the standardized mean difference (SMD) and the corresponding 95% confidence interval (CI). The dose-response association was evaluated using a restricted cubic spline model.

DATA SYNTHESIS

Seven RCTs involving 527 patients were included. Meta-analysis revealed a statistically significant effect in favor of KT on pain intensity (SMD = -1.71; 95% CI = -2.51 to -0.90; P = <0.001) and on disability (SMD = -1.15; 95% CI = -2.29 to -0.02; P = <0.001). The total duration of KT use ranged from 5 to 35 days. It was estimated that a dose of 5-10 days exceeded the minimal clinically important difference (MCID) for pain intensity (mean difference at 10 days = -2.63; 95% CI = -3.05 to -2.22). Low certainty of evidence was identified for both outcomes.

CONCLUSIONS

In pregnant women with lumbo-pelvic pain, the use of KT for 5 to 10 days produces a short-term reduction in pain intensity that exceeds the MCID, with a low certainty of evidence.

PURPOSE OF REVIEW

This paper is an update of the publications on Transitional Pain Services and explores the viability of a dedicated transitional pain service for women.

RECENT FINDINGS

We address common pain pathologies establishing referral criteria, pathways, and effective strategies to decrease chronification of pain during pregnancy.

SUMMARY

This review highlights the importance establishing transitional pain service models at every institution and in particular in obstetric population as pain is normalized by Society during pregnancy.

The correlation between pregnancy-related low back pain and physical fitness evaluated by an index system of maternal physical fitness test

To investigate incidence of pregnancy-related low back pain (LBP), evaluate physical fitness objectively during pregnancy and analyze the correlation between LBP and physical fitness of pregnant women, 180 pregnant women including 101 in mid-gestation (14-28 gestational weeks) and 79 in late-gestation (28-37 gestational weeks) were recruited and self-reported their LBP. The aerobic ability such as cardiorespiratory fitness and anaerobic ability including strength, endurance, speed, flexibility, and balance were evaluated by a novel materal physical fitness test system. The correlation between LBP and each component in physical fitness test system was analyzed in SPSS. As the results, 135 out of 180 participants (75% of total) had pregnancy-related LBP. Physical fitness of participants in late-gestation was significantly weaker including weaker back strength (p<0.05), less resistance band pullbacks in 30s (p<0.01), less stretching in sit-and-reach test (p<0.001), shorter duration in left legged blind balance test (p<0.05) and weaker bird dog balance(p<0.05) than those in mid-gestation. Correlation analysis indicated that LBP was negatively associated with standing heel raises in 20s (p<0.01) and standing glute kickbacks in 30s (left p<0.01, right p<0.05). Thus, it is concluded that LBP is in high prevalence throughout the entire pregnant course. The pregnant women are prone to have weakened strength of core muscle groups and poorer flexibility and balance along the pregnancy. In addition, their LBP was negatively correlated to strength of back muscle groups of lower limbs.

Incidence of fracture hospitalization and surgery during pregnancy in Finland-1998-2017: a retrospective register-based cohort study

INTRODUCTION

The aim of this study was to assess the incidence of all major fractures and surgery during pregnancy and the outcomes of pregnancy in Finland between 1998 and 2017.

MATERIALS AND METHODS

A retrospective cohort study using nationwide data from the Finnish Care Register for Health Care and the Finnish Medical Birth Register. As participants we included all women aged between 15 and 49 years from January 1, 1998 to December 31, 2017 and their ≥ 22-week pregnancies.

RESULTS

Of a total 629,911 pregnancies, 1813 pregnant women were hospitalized with a fracture diagnosis, yielding an incidence of 247 fractures/100,000 pregnancy-years. Of these, 24% (n = 513/2098) were treated operatively. The most common fractures were fractures of the tibia, ankle, and the forearm, which made up half of all fractures. The incidence of pelvic fractures was 6.8/100,000 pregnancy-years, with an operation rate of 14%. The stillbirth rate of all fracture patients was low at 0.6% (n = 10/1813), although this was 1.5-fold the overall stillbirth rate in Finland. Lumbosacral and comminuted spinopelvic fractures resulted in preterm delivery in 25% (n = 5/20) of parturients, with a stillbirth rate of 10% (n = 2/20).

CONCLUSION

The incidence of fracture hospitalization during pregnancy is lower than in the general population, and fractures in this population are more often treated conservatively. A higher proportion of preterm deliveries and stillbirths occurred in women with lumbosacral and comminuted spinopelvic fractures. Maternal mortality and stillbirth rates remain low among women with fractures leading to hospitalization or surgery during pregnancy.

Posterior decompression and stabilization in a pregnant patient with traumatic lumbar fracture: A case report

Spine fractures with or without spinal cord injury in the pregnant population are rare, with few reported cases. A 25-year-old primigravida at 24 weeks of gestation presented after falling off a fast-moving motorcycle one month prior. She had sustained a severe back injury and had difficulty walking. Magnetic resonance imaging showed an acute kyphosis secondary to comminuted anterior wedge compression fractures of the L2 and L3 vertebral bodies and L2/3 disc involvement with retropulsion of the fracture fragments into the central canal resulting in severe central canal stenosis. After multidisciplinary discussion, the patient underwent posterior decompression, reduction and stabilization with pedicle screws. The patient had good neurological recovery at discharge and the pregnancy progressed normally. Three months later, at 39 weeks of gestation, the patient had an uneventful spontaneous delivery of a healthy baby. This case illustrates the importance of multidisciplinary management of spinal cord injury in a pregnant patient.

A Study from a Highly Populated Country : Risk Factors Associated with Lower Back Pain in Middle-Aged Adults

OBJECTIVE

Low back pain (LBP) is a global health problem that affects the productivity of the patients. Several factors such as individual, occupational, and psychosocial factors increase the risk of LBP. However, only a few studies investigated those factors, especially in middle adulthood in Indonesia. Indonesia is a country with a young population that has been rapidly developing in recent years. This study was conducted to find out the factors associated with LBP in middle adulthood.

METHODS

This study is a cross-sectional observational analytic study using a convenience sampling method with a total sample of 3005 respondents. Data were collected using a questionnaire which was then analyzed using the chi-square test, Kolmogorovsmirnov, Spearman's Rank, and logistic regression test.

RESULTS

From the result of this study, it was found that the 12-month prevalence of LBP in middle-aged adults was 44,29%. Female (odds ratio [OR], 1.3; 95% confidence interval [Cl], 1.098-1.545; p=0.002), lack of physical exercises (OR, 0.87; 95% Cl, 0.794-0.959; p=0.005), high body mass index (OR, 1.09; 95% Cl, 1.009-1.187; p=0.002), stress level (OR, 1.26; 95% Cl, 1.088-1.458; p=0.002), and years of work experience (OR, 1.1; 95% Cl, 1.001-1.225; p=0.047) were determined as risk factors that significantly associated with LBP.

CONCLUSION

LBP is quite common among middle-aged adults in Indonesia. Female gender, higher body mass index, lack of physical activity, stress level, and years of work experience were all potential risk factors for LBP in middle-aged adults. Middle-aged adults in Indonesia should be aware of LBP and avoid disabilities by identifying risk factors that may worsen LBP in the future.

Neurosurgical emergencies during pregnancy - Management dilemmas

Background

Neurosurgical emergencies in the obstetric setting pose considerable challenges. Decision-making involves deliberations on the gestational age, critical nature of the illness, timing of surgery, maternal positioning during neurosurgery, anesthesiologic strategies, monitoring of the pregnancy during surgery, and the mode of delivery. The present study discusses the management and ethical dilemmas encountered during the management of six obstetric patients with neurosurgical emergencies.

Methods

A retrospective review of all neurosurgical operations performed between January 2016 and December 2022 were included in the study.

Results

This study includes a series of six pregnant women who presented with neurosurgical emergencies, secondary to freshly diagnosed pathologies in the period 2016-2022. The mean maternal age was 31.33 years. Four of the six patients were in the third semester and two were in the second trimester. The underlying etiologies were as follows: spontaneous intracerebral hypertensive hemorrhage (1), obstructive hydrocephalus due to shunt malfunction (1), brain tumor (02), and compressive spinal cord myelopathy due to tumors (02). Three patients who were near term underwent lower cesarean section followed by emergency neurosurgical procedure in the same sitting. Two second trimester patients continued their pregnancy after the emergency neurosurgical operation. In one patient, in whom a brain tumor was diagnosed near term, underwent neurosurgery 1 week after successful cesarean section. All the six mothers and fetus recovered well, ex3cept two patients who have persisting residual deficits.

Conclusion

Treatment of neurosurgical emergencies during pregnancy needs to be customized depending on the clinical condition of the pregnant woman, prognosis of the disease, gestational age and the status of the pregnancy. With careful planning, timely intervention, consultative decision making and it is possible to achieve the ultimate goal - which is to protect and safeguard the mother and preserve and deliver a viable fetus.

A Quick and Comprehensive Guide to Differential Diagnosis of Neck and Back Pain: a Narrative Review

The list of diagnostic options when approaching a patient with axial pain is impressively complex. Many offer limited diagnostic workups, but we could not find a truly comprehensive diagnostic guide to assist in the diagnostic evaluation. In this short paper, we briefly described a long list of medical conditions, each of which can manifest as back or neck pain, and whose prevalence ranges from common to very rare. We then proposed an algorithm for classifying them into subgroups. Further referral to diagnostic tests and specialist consultations, after assignment to one of those subgroups, could save time and unnecessary tests. We believe that this review and the proposed diagnostic algorithm can be valuable for medical education and for use in the primary care setting for the diagnostic evaluation of any type of back or neck pain in all patient groups.

Sudden perceived absence of foetal movement - a unique presentation of a vertebral haemangioma in pregnancy

OBJECTIVE

Symptomatic vertebral haemangiomas that present during pregnancy are extremely uncommon with few cases reported in literature. Epidural haemangiomas are rarer still with few documented.

METHODS

In this report, we describe the case of a 22-year-old pregnant patient who presented with apparent loss of foetal movement at 38 weeks' gestation. Clinical review demonstrated the foetus was well but neurological examination revealed lower limb paresthesia, paresis and evident uterine hypoesthesia. An MRI scan illustrated a haemangioma in the T1 vertebral body with an epidural component causing cord compression.

RESULTS

The management of spinal haemangiomas that present during pregnancy is a complex clinical scenario, which requires careful multidisciplinary consideration to determine if surgical intervention is appropriate. In this case, the patient had an emergency caesarean section followed by posterior decompression and laminectomy of the T1 vertebra with excellent post-operative recovery.

CONCLUSION

Gestational increase in the size of vertebral haemangiomas is well documented. We discuss a rare case in which a young pregnant patient presents with an atypical symptom of a vertebral haemangioma (uterine hypoesthesia). This case highlights the importance of prompt imaging in these scenarios and a cohesive multidisciplinary approach in order to provide optimal treatment for the patient.

MRI in Pregnancy and Precision Medicine: A Review from Literature

Magnetic resonance imaging (MRI) offers excellent spatial and contrast resolution for evaluating a wide variety of pathologies, without exposing patients to ionizing radiations. Additionally, MRI offers reproducible diagnostic imaging results that are not operator-dependent, a major advantage over ultrasound. MRI is commonly used in pregnant women to evaluate, most frequently, acute abdominal and pelvic pain or placental abnormalities, as well as neurological or fetal abnormalities, infections, or neoplasms. However, to date, our knowledge about MRI safety during pregnancy, especially about the administration of gadolinium-based contrast agents, which are able to cross the placental barrier, is still limited, raising concerns about possible negative effects on both the mother and the health of the fetus. Contrast agents that are unable to cross the placenta in a way that is safe for the fetus are desirable. In recent years, some preclinical studies, carried out in rodent models, have evaluated the role of long circulating liposomal nanoparticle-based blood-pool gadolinium contrast agents that do not penetrate the placental barrier due to their size and therefore do not expose the fetus to the contrast agent during pregnancy, preserving it from any hypothetical risks. Hence, we performed a literature review focusing on contrast and non-contrast MRI use during pregnancy.

Methods of Delivery in Pregnant Women with Lumbar Disc Herniation: A Narrative Review of General Management and Case Report

Low back pain is a common complaint during pregnancy, affecting approximately half of pregnant women. However, true disc herniation is extremely rare, and the majority of patients heal without surgery. The purpose of this study was to provide an overview of conservative management strategies and delivery modes for pregnant patients suffering from lumbar disc herniation without severe neurologic deficits that would require emergency surgery. We performed a narrative review of the literature using the PubMed database. Thirty-one articles were originally retrieved, out of which 7 met the inclusion criteria, compiling a total of 10 cases of parturient patients with lumbar disc hernia treated conservatively until childbirth. The preferred delivery mode was a Cesarean section, which was performed in 6 out of 10 cases. Two patients developed the cauda equina syndrome, one during a failed induction and the other patient 4 weeks after vacuum extraction. However, the second patient failed to improve after surgery. No patients developed cauda equina syndrome during or after the Cesarean section. Based on limited data, the Cesarean section seems to be preferred compared to vaginal delivery to avoid worsening symptoms and progression to the cauda equina syndrome.

The Management of Symptomatic Lumbar Disc Herniation in Pregnancy: A Systematic Review

STUDY DESIGN

Systematic review.

OBJECTIVES

Lumbar disc herniation (LDH) has been reported to affect 1 in 10 000 pregnant women. There is limited evidence available regarding the optimal management of LDH in pregnant patients. We aimed to review the current evidence for the management of symptomatic LDH in pregnancy through critical appraisal and analysis of the available literature.

METHODS

Searches were conducted in Medline, Embase, PubMed, Science Direct, and The Cochrane Library from inception using predetermined search terms. All peer-reviewed studies of pregnant women with symptomatic LDH were included. The quality of eligible articles was assessed and extracted data and characteristics were pooled for analysis. References cited by studies were screened to identify other relevant publications.

RESULTS

Thirty studies involving 52 patients were identified. Compared to surgically managed patients, conservatively managed patients had a higher full recovery rate (61.54% vs 56.41%) and reported a lower rate of persistent symptoms (30.77% vs 38.54%). Compared to patients who were treated surgically for cauda equina syndrome, patients treated surgically for sciatica had a higher full recovery rate (80.95% vs 27.78%) and reported a lower rate of persistent symptoms (14.29% vs 66.67%).

CONCLUSION

There is limited evidence to guide the management of pregnant patients with LDH. Despite a suggestion toward improved outcomes with conservative management, the presence of selection bias and the overall poor quality of current research precludes reliable conclusions from being drawn. Decision making for this patient group should be undertaken within a multidisciplinary setting.

Risk Factors Associated with Low Back Pain among A Group of 1510 Pregnant Women

Background: Low Back Pain (LBP) is a frequent, very common, and costly health problem. LBP, which occurs during pregnancy, may become a lifelong problem. The aim of this study was to determine the risk factors associated with LBP in pregnant women. Methods: The study included 1510 pregnant women. A questionnaire assessing demography, lifestyle, prevalence, and characteristics was designed and used in the study. Pain intensity was assessed with the VAS (Visual Analogue Scale). The RMDQ (Roland Morris Disability Questionnaire) was used to assess the effect that low back pain had on the functional capacity of a pregnant woman. Middle (thoracic) and low back pain disability was measured with the help of the ODI (Oswestry Disability Index) questionnaire. Results: The study confirmed that lying/sleeping (49.6%) and sitting positions (38.7%) as well as walking (37.2%) are the most significant factors causing LBP. It was also found that women who had not engaged in physical activity were more likely to experience LBP. Conclusions: Predisposing factors for LBP in pregnancy are LBP in previous pregnancies, back pain during menstruation, a younger age and a lack of physical activity. Most women in pregnancy with LBP experienced minimal and mild disability.

Lumbar Intervertebral Disc Degeneration as a Common Incidental Finding in Young Pregnant Women as Observed on Prenatal Magnetic Resonance Imaging

Background: Obstetric imaging, subserving fetal evaluation, may yield incidental maternal findings. Based on prenatal magnetic resonance (MR) imaging, this study aims to investigate incidental intervertebral disc degeneration and displacement in young, pregnant women. Methods: This retrospective study included the sagittal 1.5 Tesla, T2-weighted lumbar spine images of 943 pregnant Central Europeans (age range, 18-47 years), who initially had undergone MR imaging because of sonographically suspected fetal abnormalities. Qualitatively, 4715 lumbar intervertebral discs were evaluated for degeneration using a modified Pfirrmann MR classification (nondegenerated, low-grade, moderate, and high-grade degeneration), as well as for displacement. In addition to descriptive statistics, an ordinal regression analysis was performed to analyze the relationship between degeneration and the women's age, and body weight. Results: With regard to the highest degree of degeneration in each woman, 578 (61.3%) showed low-grade, 211 (22.4%) moderate, and 154 (16.3%) high-grade degeneration, and no woman had entirely nondegenerated discs. For the span from 18 to 47 years of age, moderate and high-grade degeneration increased from 6.7% to 36.7% and from 13.3% to 22.4%, respectively. Of 943 women, 57 (6%) had disc displacements, of which 97% were in conjunction with high-grade degeneration. There was a statistically significant relationship (p < 0.001) between degeneration and age, and between degeneration and body weight. Conclusions: In young pregnant women, lumbar intervertebral disc degeneration is a ubiquitous, incidental finding, increasing from the late second decade of life onward, which may be part of physiological aging, as opposed to a small percentage of incidental disc displacements.

Relationship between lower lumbar spine shape and patient bone metabolic activity as characterised by 18F NaF bio-markers

Chronic lower lumbar pain has been associated with elevated bone metabolic activity in the spine. Diagnosis of bone metabolic activity is currently through integrating Positron Emission Tomography (PET) with Sodium Fluoride (¹⁸F-NaF) biomarkers. It has been reported that numerous observable pathologies including lumbar fusion, disc abnormalities and scoliosis have often been associated with increased ¹⁸F-NaF uptake. The aim of this study was to identify what features of lower lumbar shape most strongly correlate with ¹⁸F-NaF uptake. Following a principal component analysis of 23 patients who presented with lumbar pain and underwent ¹⁸F-NaF PET-CT, it was revealed that three modes interpreted as (i) sacral tilt, (ii) vertebral disc spacing and (iii) spine size were the three characteristics that described 88.7% of spine shape in our study population. ¹⁸F-NaF was described by two modes including ¹⁸F-NaF intensity and spatial variation (anterior-inferior to posterior-superior). ¹⁸F-NaF was most sensitive to sacral tilt followed by vertebral disc spacing. A predictive model derived from that spine population was able to predict ¹⁸F-NaF 'hot-spot' locations with 85 ± 5% accuracy and with 71 ± 3% accuracy for the ¹⁸F-NaF magnitude. These results suggest that patients reporting with lower lumbar pain and who present with increased sacral tilt profiles and/or reduced disc spacing are good candidates for further ¹⁸F-NaF PET-CT imaging, evidenced by the high association between those shape profiles and ¹⁸F-NaF uptake.

Cauda equina syndrome in an obese pregnant patient secondary to double level lumbar disc herniation - A case report and review of literature

Introduction

Lumbar disc herniation during pregnancy poses a significant challenge to the spine surgeon towards achieving good clinical, maternal, and fetal outcomes. Surgical intervention is warranted in patients with significant neural deficits, and cauda equina syndrome and needs to be performed at the earliest in order to avoid irreversible neurological sequelae.

Case presentation

We report a 29-year-old primigravida in her 21st week of gestational period, who was diagnosed with cauda equina syndrome secondary to two level lumbar disc herniations. The lengthier surgical duration in performing double level disc herniations in an obese patient raises concerns in anesthetic dosing of drugs and surgical positioning which may result in fetal distress. A double level decompression and discectomy in prone position was done under general anesthesia. Despite the surgical challenges, the postoperative period was uneventful resulting in immediate pain relief and complete neurological recovery, followed by the delivery of a 2.7-kg healthy male child.

Discussion

Surgical intervention can be performed in pregnancy, to avoid irreversible neurological deficits, even in an obese individual with double level lumbar pathology. However, it is essential that the surgeon appraises the situation and involves an integrated multidisciplinary team comprising anesthetist, spine surgeon, obstetrician, and psychologist, and inculcates certain precautions in the perioperative management to achieve good surgical and fetal outcomes.

Progression of aggressive vertebral hemangiomas during pregnancy: Three case reports and literature review

RATIONALE

Vertebral hemangiomas (VHs), one of the most common benign tumors of the spine, can be aggressive, which is a rare condition and causes neurological deficits. Pregnancy is related to the worsening of aggressive VHs. The diagnosis and treatment of aggressive VHs remain challenging, especially for pregnant cases.

PATIENT CONCERNS

We report 3 cases of aggressive VH in women who developed progressive neurological deficits during pregnancy among 95 patients treated for aggressive VH in our hospital in the past 15 years.

DIAGNOSES AND INTERVENTIONS

All 3 patients experienced progressive deterioration of neurological function and pain at 13, 28, and 41 weeks' gestation. On radiological examination, VHs were the suspected radiological diagnoses in 2 patients; 1 patient was preoperatively misdiagnosed with a spinal metastatic tumor. All 3 patients underwent decompression surgery with intraoperative vertebroplasty and/or postoperative radiotherapy. The pathological diagnosis after surgery was all hemangiomas.

OUTCOMES

In all 3 patients, there were no tumor recurrences, and neurological functions remained normal at the last follow-up of 75, 38, and 15 months after the treatment, respectively.

LESSONS

Pregnancy might lead to the onset of aggressive VHs. The diagnosis and treatment of VHs during pregnancy remain controversial due to concern for both maternal and fetal safety. Timely surgery could preserve neurological function. Decompression surgery by laminectomy followed by adjuvant therapies require less skill and have a shorter surgery time, and can be considered more appropriate for aggressive VHs with pregnancy.

Gravidity, Parity, and Vertebral Dimensions in the Northern Finland Birth Cohort 1966

STUDY DESIGN

A population-based birth cohort study.

OBJECTIVE

To investigate the association between gravidity, parity, and vertebral geometry among middle-aged women.

SUMMARY OF BACKGROUND DATA

Vertebral size is a recognized determinant of vertebral fracture risk. Yet, only a few lifestyle factors that influence vertebral size are known. Pregnancy is a labile period that may affect the maternal vertebral size or shape. The lumbar lordosis angle is permanently deepened by pregnancy, but it remains unclear whether vertebral shape or size contribute to this deepened angle.

METHODS

We aimed to investigate whether gravidity and parity were associated with vertebral cross-sectional area (CSA) and height ratio (anterior height to posterior height) among 705 middle-aged women from the Northern Finland Birth Cohort 1966. We measured the corpus of their fourth lumbar vertebra using magnetic resonance imaging of the lumbar spine at the age of 46. Gravidity and parity were elicited using a questionnaire also at the age of 46. Linear regression analysis was used with adjustments for body mass index, vertebral CSA (height ratio models), and vertebral height (CSA models). We also ran a subgroup analysis that did not include nulliparous women, and we compared nulliparous women with grand multiparous women.

RESULTS

The models found no statistically significant associations between the predictors and outcomes. Crude and adjusted results were highly similar, and the subgroup analyses provided analogous results.

CONCLUSION

Pregnancy, or even multiple pregnancies, do not seem to have long-term effects on vertebral geometry. In order to enhance the prevention of vertebral fractures, future studies should aim to reveal more lifestyle determinants of vertebral size.

Low back pain in pregnant women attending antenatal clinic: The Aminu Kano teaching hospital experience

Background:

The profound physiologic effects of pregnancy affect the musculoskeletal system. Pregnant women are at increased risks of low back/pelvic girdle pains.

Objective:

To determine the incidence of low back/pelvic girdle pains among pregnant women.

Materials and Methods:

This was a cross-sectional study conducted from May 1 to June 30, 2016, among consenting pregnant women at Aminu Kano Teaching Hospital. Ethical approval was obtained from the Hospital Ethics Committee. Information was obtained in a questionnaire on consecutive pregnant women. Data obtained were analyzed using SPSS version 18 (SPSS Inc., Chicago, Illinois, USA, 2012). Fisher's exact test was used for categorical data, and P ≤ 0.05 was considered statistically significant.

Results:

A total of 309 pregnant women were recruited from May 1 to June 30, 2016. The mean age ± standard deviation was 28.4 ± 5.86 years. The incidence of low back pains (LBPs) and pelvic girdle pains among the pregnant women was 106 (34.3%) and 178 (57.6%), respectively. The pain was severe among 26 (9.2%) pregnant women, which warranted analgesic usage. Pain radiation was reported in >50% of cases. There was an incidental finding of urinary incontinence in 36 (12.6%) cases. Low back/pelvic girdle pain was not associated with body mass index (BMI) (P = 0.390).

Conclusion:

The incidence of LBPs and pelvic girdle pains was high and found to be 34.3% and 57.6%, respectively. Analgesics were used especially among those with severe pains. There was an incidental finding of urinary incontinence among pregnant women with complaints of low back/pelvic girdle pains. There was no statistically significant association between LBPs and maternal BMI.

Low Back Pain and Pelvic Girdle Pain in Pregnancy

Pregnancy has a profound effect on the human body, particularly the musculoskeletal system. Hormonal changes cause ligamentous joint laxity, weight gain, and a shift in the center of gravity that leads to lumbar spine hyperlordosis and anterior tilting of the pelvis. In addition, vascular changes may lead to compromised metabolic supply in the low back. The most common musculoskeletal complaints in pregnancy are low back pain and/or pelvic girdle pain. They can be diagnosed and differentiated from each other by history taking, clinical examination, provocative test maneuvers, and imaging. Management ranges from conservative and pharmacologic measures to surgical treatment. Depending on the situation, and given the unique challenges pregnancy places on the human body and the special consideration that must be given to the fetus, an orthopaedic surgeon and the obstetrician may have to develop a plan of care together regarding labor and delivery or when surgical interventions are indicated.

Neuroradiology in women of childbearing age

PURPOSE OF REVIEW

This review summarizes safety concerns associated with diagnostic neuroimaging in patients who are of childbearing age, focusing on diagnostic modalities and radiologic features of neurologic conditions encountered by pregnant women.

RECENT FINDINGS

During pregnancy, women experience a range of physiologic changes that can affect neurologic function. These include endocrine, hemodynamic, endothelial, immunologic, and coagulopathic changes that can alter susceptibility to stroke, subarachnoid hemorrhage, demyelination, venous thrombosis, and other neurologic conditions. Unique safety concerns are associated with imaging procedures performed to diagnose neurologic conditions that occur during pregnancy.

SUMMARY

This review discusses the use of diagnostic neuroimaging, including administration of IV contrast, in pregnant women and in nonpregnant women of childbearing age.

The effect of chronic pelvic pain scoring on pre-term delivery rate

A total of 57 pregnant women, who were admitted to the outpatient clinic having high visual analogue scale (VAS) and a history of chronic pelvic pain before pregnancy, were evaluated with the international pelvic pain assessment form (IPPAF). Gynaecological disorders, pain at ovulation, dysmenorrhoea, level of cramps with period and suspicion of endometriosis were determined to be higher in the pre-term group (p < 0.05). Regarding urological disorders, pain when the bladder was full, pain with urination, a positive answer to the question, 'Does your urgency bother you?' and suspicion of interstitial cystitis were also determined to be higher in the pre-term group (p < 0.05). Thus, the total IPPAF scores were significantly higher in the pre-term group (p < 0.05). The pregnant women with a higher total IPPAF score before pregnancy may thus have a higher probability of pre-term labour.

FRACTURE-DISLOCATION OF THE THORACIC SPINE DURING SECOND TRIMESTER OF PREGNANCY: CASE REPORT AND LITERATURE REVIEW

Spinal fractures associated with spinal cord injury rarely affect pregnant patients. The authors present the case of a 20-year-old woman in her 20^th week of pregnancy, who suffered fracture-dislocation of the thoracic spine (T4-T5) and underwent decompression, reduction and posterior fusion with pedicle screws. Despite the complete spinal cord injury presented, the pregnancy progressed uneventfully and resulted in birth via normal delivery of a healthy newborn at term. Some particular features of this case, like the care needed in using ionizing radiation, the surgical approach and delivery, use of steroids and pregnancy complications in such patients are discussed here. Only a multidisciplinary team composed by physicians from different specialties (spinal surgeons, obstetricians and physiatrists), nurses and physiotherapists is capable of assisting pregnant patients with spinal cord injuries satisfactorily.

A systematic review of the global prevalence of low back pain

OBJECTIVE

To perform a systematic review of the global prevalence of low back pain, and to examine the influence that case definition, prevalence period, and other variables have on prevalence.

METHODS

We conducted a new systematic review of the global prevalence of low back pain that included general population studies published between 1980 and 2009. A total of 165 studies from 54 countries were identified. Of these, 64% had been published since the last comparable review.

RESULTS

Low back pain was shown to be a major problem throughout the world, with the highest prevalence among female individuals and those aged 40-80 years. After adjusting for methodologic variation, the mean ± SEM point prevalence was estimated to be 11.9 ± 2.0%, and the 1-month prevalence was estimated to be 23.2 ± 2.9%.

CONCLUSION

As the population ages, the global number of individuals with low back pain is likely to increase substantially over the coming decades. Investigators are encouraged to adopt recent recommendations for a standard definition of low back pain and to consult a recently developed tool for assessing the risk of bias of prevalence studies.

Surgery for Recurrent Lumbar Disc Herniation During Pregnancy: A Case Report

A few cases of lumbar disc herniation (LDH) that have been treated by surgery during pregnancy have been reported in the literature. However, symptomatic recurrent LDH during pregnancy has been rarely reported. A 32-year-old parous woman presented with lumbago and severe right leg pain at 20 weeks' gestation. Eleven years prior to admission, she had undergone an open discectomy for right-sided LDH at the L4-5 level. Magnetic resonance imaging (MRI) showed a recurrent disc herniation that affected the nerve root at the right L4-5 level. The radiating pain did not respond to conservative treat-ment. Revision surgery was performed under general anesthesia and in the left lateral position to avoid fetal stress and aortocaval compression, and the ruptured disc particle was completely removed.
