Aims. The number of females within the speciality of trauma and orthopaedics (T&O) is increasing. The aim of this study was to identify: 1) current attitudes and behaviours of UK female T&O surgeons towards pregnancy; 2) any barriers faced towards pregnancy with a career in T&O surgery; and 3) areas for improvement. Methods. This is a cross-sectional study using an anonymous 13-section web-based survey distributed to female-identifying T&O trainees, speciality and associate specialist surgeons (SASs) and locally employed doctors (LEDs), fellows, and consultants in the UK. Demographic data was collected as well as closed and open questions with adaptive answering relating to attitudes towards childbearing and experiences of fertility and complications associated with pregnancy. A descriptive data analysis was carried out. Results. A total of 226 UK female T&O surgeons completed the survey. All regions of the UK were represented. Overall, 99/226 (44%) of respondents had at least one child, while 21/226 (9.3%) did not want children. Median age at first child was 33 years (interquartile range 32 to 36). Two-thirds (149/226; 66%) of respondents delayed childbearing due to a career in T&O and 140/226 (69%) of respondents had experienced bias from colleagues directed at female T&O surgeons having children during training. Nearly 24/121 (20%) of respondents required fertility assistance, 35/121 (28.9%) had experienced a miscarriage, and 53/121 (43.8%) had experienced obstetric complications. Conclusion. A large proportion of female T&O surgeons have and want children. T&O surgeons in the UK delay childbearing, have experienced bias and have high rates of infertility and obstetric complications. The information from this study will support female T&O surgeons with decision making and assist employers with workforce planning. Further steps are necessary in order to support female T&O surgeons having families. Cite this article: Bone Jt Open 2023;4(12):970–979

Aims. As an increasing number of female surgeons are choosing orthopaedics, it is important to recognize the impact of pregnancy within this cohort. The aim of this review was to examine common themes and data surrounding pregnancy, parenthood, and fertility within orthopaedics. Methods. A systematic review was conducted by searching Medline, Emcare, Embase, PsycINFO, OrthoSearch, and the Cochrane Library in November 2022. The Preferred Reporting Items for Systematic Reviews and Meta Analysis were adhered to. Original research papers that focused on pregnancy and/or parenthood within orthopaedic surgery were included for review. Results. Of 1,205 papers, 19 met the inclusion criteria. Our results found that orthopaedic surgeons have higher reported rates of obstetric complications, congenital abnormalities, and infertility compared to the general population. They were noted to have children at a later age and voluntarily delayed childbearing. Negative perceptions of pregnancy from fellow trainees and programme directors were identified. Conclusion. Female orthopaedic surgeons have high rates of obstetric complications and infertility. Negative perceptions surrounding pregnancy can lead to orthopaedic surgeons voluntarily delaying childbearing. There is a need for a pregnancy-positive culture shift combined with formalized guidelines and female mentorship to create a more supportive environment for pregnancy within orthopaedic surgery.

The number of women entering medical school has been steadily increasing over the past two decades; however, the number of women pursuing careers in orthopaedic surgery has not increased at the same rate. One of the suggested reasons for this discrepancy is the perceived incompatibility of having a family while upholding the demands of a surgical career in orthopaedics. A growing body of scientific literature has also outlined the increased rate of infertility and pregnancy complications in women surgeons. The extent to which these factors play a role in the recruitment and retention of women in orthopaedic surgery is unknown. Understanding pregnancy and parenthood in orthopaedic surgery is a critical first step in addressing this issue. A scoping review was conducted to identify literature pertaining to the perceptions and experiences of pregnancy and/or parenthood of women in orthopaedic surgery. Embase, MEDLINE and PsychINFO were searched on June 7th, 2021 with Boolean operators to combine the following terms: orthop?e*, pregnancy, maternity, motherhood, parenthood, parental, and parenting. Studies pertaining to orthopaedic surgery residents, fellows and staff were included. The Arksey and O'Malley framework for scoping studies was followed. Descriptive statistics were used to quantify the included studies while thematic analysis as described by Braun and Clarke was used to analyze the qualitative data. A total of 17 studies from 2006 to 2021 met inclusion criteria. Over half of the available research was conducted within the last two years (n=9, 53%). The majority of studies were conducted in the United States (n=15, 88%) and the United Kingdom (n=2, 12%). The most commonly used study design was survey-based research (n=13, 76%), followed by review studies (n=3, 18%), and case series (n=1, 6%). Thematic analysis revealed five key themes contributing to the women's experiences of pregnancy and/or parenthood in orthopaedics: (1) women are subtly or blatantly discouraged from becoming pregnant by their colleagues and superiors, (2) women delay childbearing to preserve their professional reputation, (3) there are higher rates of infertility and preterm labor in orthopaedic surgeons than in the general population, (4) the orthopaedic work environment can be hazardous and challenging for the pregnant woman, but accommodations are possible to mitigate risks, and (5) overall, there is limited support for pregnant and/or parenting women in orthopaedics throughout their career. The first woman to be board-certified in orthopaedic surgery in the United States was Ruth Jackson in 1937. Eighty-four years later, orthopaedic surgery has the lowest number of women of the surgical specialties. The barriers related to pregnancy and/or parenthood during a woman's career in orthopaedics may be one cause. This study identified five themes related to pregnancy and parenthood that warrant further investigation. Qualitative research approaches can be used to elucidate the details of women's experiences and to provide suggestions for structural changes in the orthopaedic work environment

We surveyed 343 young women with 420 total hip arthroplasties (THAs) regarding pregnancy and childbirth after THA. The mean age at surgery was 35 years (18 to 45). The mean length of follow-up after the initial arthroplasty was 16 years (6 to 27). Of these 343 women, 47 (13.7%) had a successful pregnancy after their primary THA. The first baby after a THA was delivered vaginally in 30 patients and by Caesarean section in 17. Of the 343 patients, 138 underwent a revision. For the entire series, the risk of revision at five years was 5%, at ten years 24%, and at 20 years 50%. After adjusting for age at surgical intervention, the risk of revision was not significantly associated with childbirth. Of the 47 patients who had a successful pregnancy, 28 (60%) noted an increase in pain in the hip during pregnancy and ten of these patients had persistent pain after their pregnancy. Seven patients complained of pain in the groin in the replaced hip after childbirth. At the time of this survey, five of these patients (70%) had had revision THA. Childbirth is not affected by the presence of a THA. Pregnancy after THA is not associated with decreased survival of the prosthesis. Pain in the hip is common during pregnancy in these patients. Pain in the groin which persists after delivery commonly leads to revision of the THA

The case histories of these Black Notley patients show that no serious harmful effects have been caused by pregnancies going to full term. Most of the patients had normal confinements; Caesarian sections were few and were usually done for obstetric reasons, not for fear of reactivation of the disease. This experience bears out a remark made to me by Marcel Galland. When asked if Caesarian sections were required for women who became pregnant after treatment at Berck for skeletal tuberculosis, he replied: "Jarnais! Tout passe!". Two patients in the series had artificial abortions, and one aborted spontaneously. Two of these three patients did not do as well as other patients whose pregnancies went to full term. Quite another question is whether the onset of skeletal tuberculosis sooii after pregnancy may be attributed to the pregnancy. In a group of women of child-bearing age, it would be difficult to distinguish between post hoc and propter hoc in considering this question. One patient of this series, H. Q. (Case 25), was admitted eight months pregnant with active tuberculosis of the knee; but pain in the joint had started fifteen months before admission, and the onset of disease no doubt preceded the pregnancy. Some of the patients admitted to Black Notley were mothers of young children hut there is no note of any pregnancy having preceded the onset of tuberculosis by a short interval. The follow-up reports of the married patients compare favourably with those of the unmarried. Further, it may be argued that pregnancy increases resistance to tuberculosis. Such a belief was current from the time of Hippocrates until the middle of the nineteenth century, and clinical evidence can be quoted in favour of such a view. In America, Lyman (1943) followed up 1,818 women who had been treated for tuberculosis in a sanatorium; many had married despite medical advice to the contrary. Lyman found that the late results of treatment were four times as good in the married patients as in the single women. Lyman says, "When we consider that the married group established this record in spite of the fact that 192 out of 315 gave histories of pregnancies (averaging 2·25 children each), it is clear that some factor not yet accounted for has exerted a profound influence in their cases.". I have speculated elsewhere as to what this factor may be (Wilkinson 1949). But it seems clear that increased sterol circulation in the body is associated with increased reticulo-endothelial activity (Fraser 1935). Thus reticulo-endothelial proliferation has been observed in the lesions of lupus following the administration of calciferol (Dowling, Gauvain and Macrae 1948). An increase of blood cholesterol is found during pregnancy. The sex hormones are sterols and might be expected to be raised in the marital state; it is perhaps significant that marital contacts form a group relatively immune to tuberculosis. There would appear to be good grounds for reassuring the married woman who has suffered from skeletal tuberculosis regarding the prospect of normal pregnancy. Many letters received from patients in a follow-up of this sort are poignant documents. There is no doubt that the majority of these women desire children as ardently as normal women, and that a safe confinement following skeletal tuberculosis is an excellent form of rehabilitation

To investigate the fears of female patients of child bearing age, who required surgical stabilisation for pelvic fractures, and to assess the outcomes of subsequent pregnancy. Between 1990 & 2002 from a prospectively kept database in our institution, patients sustaining pelvic fractures requiring surgery who were women under 35 years of age at the time of injury were identified and included in this study. Patient’s medical records and radiographs (birth canal status) were reviewed and data collected. All the patients were attempted to be contacted by telephone and a questionnaire completed recording the type of pelvic injury, previous obstetric history, fears regarding future pregnancy, pregnancy outcomes, Euroqol pain scores pre & post fracture and painkiller usage. Those who were unable to be contacted by telephone, were followed up by a postal questionnaire. The mean time of follow up from injury was 4.2 years (range 1 to 12 years). Out of 554 patients, 197 (36%) were women and of these, 54 (27%) patients were less than 35 years old at the time of injury. A telephone questionnaire was completed on 31 patients [57 % (study group)], results from the postal questionnaire are being collated. The mean age of the study group at injury was 23.3 years (range 6 to 34 years). There were 14 (45 %) isolated ace-tabular fractures and 17 (55 %) pelvic ring fractures. 11 (36 %) had previously had children prior to the injury, and 22 (71 %) had planned to have children in the future, prior to fracture. 23 (74 %) had expressed fears related to their future ability to have children. Out of 8 (26 %) patients who had subsequent pregnancies, only 1 (12.5%) had a normal vaginal delivery. Out of the rest, 3 (37.5%) patients had investigations for pelvic disproportion; 2 (20%) went on to elective caesarean section for disproportion; 1 patient requested an elective section after concerns regarding delivery; 1 patient had a ventouse assisted delivery for delayed second stage; 1 patient had an ectopic pregnancy; 1 patient had a miscarriage at 18 weeks gestation and 1 patient had infertility problems. 4 out of 31 (13%) patients were advised against future pregnancy and one patient underwent a tubal ligation following this advice. Pelvic fractures represent a serious group of injuries; after initial recovery, many female patients have serious concerns regarding future pregnancy. A number will go on to have further pregnancies, and many will suffer the risk of complications following their pelvic injury

Introduction: There are protocols on the management of polytrauma in obstetric patients. However, there is little information about osteo-articular injuries sustained in these patients. The object of this study is to review the management of these patients and to suggest a guideline. Material and method: Inclusion criteria: Pregnant patients treated during the last 6 years, treated as inpatients in our center during pregnancy due to osteo-articular injuries. Variables studied: Gestational age, mechanism of injury, fracture type, management, termination of pregnancy and sequelae. Results: We treated 13 patients with 21 fractures in our center, with an incidenc of 2,13 fractures/10.000 births. The mechanism of injury was low degree trauma in 6 cases (60% 3rd trimester) and high-degree in 7 (83% 1st and 2nd trimester). There was a predominance of lower extremity fractures, especially tibia and fibula (7 cases) and pelvis (3 cases). Gestational age was 1st trimester (3 cases), 2nd trimester (5 cases), 3rd trimester (5 cases). 10 women were treated surgically, 8 before finishing gestation. Gestation ended as and induced abortion (3 cases, 1 due to fetal death and 2 due to teratogenic risk), and birth (10 cases, all alive, 50% eutocic). Only 3 babies needed type II or type III neonatal reanimation. CONCLUSIONS: Pregnant women can get injured by low-energy trauma, especially during the third trimester. Pregnancy does not necessarily compromise surgical management of fractures. We review diagnostic and therapeutic management strategies for these patients

Degenerative spondylolisthesis is most common at the L4/L5 level and in women. There are several possible reasons for its predilection at this site, but there is no satisfactory explanation for the predominance in women. We considered that pregnancy was a possible influence. We reviewed the records and radiographs of 949 women and 120 men aged 50 years and over who had attended a spinal surgeon for low back pain over a five-year period. We found that women who had borne children had a significantly higher incidence of degenerative spondylolisthesis than nulliparous women (28% v 16.7%; p = 0.043). The men had a 7.5% incidence, significantly less than nulliparous women (p = 0.031). Our results suggest that pregnancy is an important factor in the aetiology of degenerative spondylolisthesis

Only two cases have been reported of congenital dislocation of the hip in infants born after extrauterine pregnancies. We report a further two and discuss the management and the variable outcome. These cases seem to confirm that congenital dislocation of the hip is associated with moulding forces rather than being a teratological abnormality

Introduction. Metal-on-Metal (MoM) bearing surfaces were historically used for young patients undergoing total hip arthroplasty, and remain commonplace in modern hip resurfacing. In theory, it has been postulated that metal ions released from such implants may cross the placental barrier and cause harm to the fetus. In light of this potential risk, recommendations against the use of MoM components in women of child-bearing age have been advocated. The purpose of this systematic review was to evaluate: 1) the Metal-on-Metal bearing types and ion levels found; 2) the concentrations of metals in maternal circulation and the umbilical cord; and 3) the presence of abnormalities in the fetus. Methods. A comprehensive literature review was conducted of studies published between January 1st, 1975 and April 1st, 2019 using specific keywords. (See Fig 1). We defined the inclusion criteria for qualifying studies for this review as follows: 1) studies that reported on the women who experienced pregnancy and who had a Metal-on-Metal hip implant; 2) studies that reported on maternal metal ions blood and umbilical cord levels; and 3) studies that reported on the occurrence of fetal complications. Data on cobalt and chromium ion levels in the maternal blood and umbilical cord blood, as well as the presence of adverse effects in the infant were collected. Age at parturition and time from MoM implant to parturition were also collected. A total of 6 studies were included in the final analysis that reported on a total of 21 females and 21 infants born. The mean age at parturition was 40 years (range, 24–41 years), and the mean time from MoM implantation to parturition was 47.2 months (range, 11–119 months). Results. Maternal blood cobalt levels were found as a weighted average of 33.94ug/L (0.972–143), while umbilical cord blood cobalt levels were found to be 22.07 ug/L(0.486–75). Cobalt levels were reduced by an average of 35% between maternal and umbilical cord blood. Maternal cord blood chromium levels were found as a weighted average of 9.25 ug/L (1–25), while umbilical cord chromium levels were found to be 1.30 ug/L(0.288–2.3). Chromium levels were reduced by an average of 86% between maternal and umbilical cord blood. No cobalt or chromium was detected in the umbilical cord blood of three patients. Out of the 21 infants born to women with MoM implants, 20 were born healthy with no adverse effects or complications. Conclusion. To date, there is a lack of consensus as to whether Metal-on-Metal hip arthroplasty implants are to be avoided in the child-bearing female population and whether it constitute a hazard to the fetus in-utero. Both chromium and cobalt ions were markedly reduced in levels when transitioning from maternal to cord blood. In particular, chromium showed a greater reduction on average than cobalt (86% vs. 35%). Based on the current evidence, there appears to be no correlation between the presence of metal ions in umbilical cord blood and complications, particularly congenital malformations in the fetus, as none of the infants experienced abnormalities uniquely attributable to the presence of metal ions.

Purpose and background. Over two-thirds of pregnant women experience low back pain (LBP) that interferes with everyday activities, work and sleep. Acupuncture appears a safe, promising intervention but there are no high quality trial data, regarding its clinical or cost-effectiveness in comparison to standard care. Methods. EASE Back was a feasibility and pilot RCT designed to inform a full trial evaluating the addition of acupuncture to standard care for pregnancy-related LBP. In preparation for the pilot trial, phase 1 of EASE Back consisted of semi-structured interviews exploring the views of pregnant women, midwives and physiotherapists about pregnancy-related LBP, use of acupuncture, and participation in clinical trials. Transcript data were anonymised and analysed using thematic analysis. Three members of the team independently coded a sample of transcripts to develop the coding framework. Results. 17 women, 15 midwives and 21 physiotherapists were interviewed (total n=53). Findings highlighted the impact of LBP in pregnancy, the paucity of effective treatment options and the challenges of recruiting pregnant women with LBP into research. Women and midwives expressed few concerns over the use and safety of acupuncture; physiotherapists were more cautious and had concerns about safety. Conclusions. Acupuncture for pregnancy- related LBP appears to be acceptable to women and midwives. Future research needs to consider strategies to support recruitment and retention, and should consider including interviews with eligible women who decline to take part in order to understand their reasons, as well as with women receiving treatment so as to understand their experiences of taking part. This abstract has not been published in whole or substantial part, nor has it been presented previously at a national meeting. Conflicts of interest: No conflicts of interest.

Radiological imaging is necessary in a wide variety of trauma and elective orthopaedic operations. The evolving orthopaedic workforce includes an increasing number of pregnant workers. Current legislation in the United Kingdom, Europe and United States allows them to choose their degree of participation, if any, with fluoroscopic procedures. For those who wish to engage in radiation-prone procedures, specific regulations apply to limit the radiation dose to the pregnant worker and unborn child. This paper considers those aspects of radiation protection, the potential effects of exposure to radiation in pregnancy and the dose of radiation from common orthopaedic procedures, which are important for safe clinical practice

Orthopaedics has been left behind in the worldwide drive towards diversity and inclusion. In the UK, only 7% of orthopaedic consultants are female. There is growing evidence that diversity increases innovation as well as patient outcomes. This paper has reviewed the literature to identify some of the common issues affecting female surgeons in orthopaedics, and ways in which we can address them: there is a wealth of evidence documenting the differences in the journey of men and women towards a consultant role. We also look at lessons learned from research in the business sector and the military. The ‘Hidden Curriculum’ is out of date and needs to enter the 21st century: microaggressions in the workplace must be challenged; we need to consider more flexible training options and support trainees who wish to become pregnant; mentors, both male and female, are imperative to provide support for trainees. The world has changed, and we need to consider how we can improve diversity to stay relevant and effective.

Introduction. The medical field has long held largely anecdotal beliefs that polymethyl methacrylate (PMMA) vapors are dangerous to a growing fetus, and as such, women who are pregnant should avoid exposure. This study investigates the perceptions of female orthopedic surgeons regarding PMMA cement exposure during pregnancy, and if it influences 1) currently held beliefs / practices and 2) clinical and career choices. Methods. A 23-question survey was distributed via e-mail to active members of the Ruth Jackson Orthopaedic Society and a private social media group for women in orthopedics. Questions included demographics, current usage of PMMA, previous exposure during pregnancy and/or breastfeeding, and beliefs regarding current or future willingness of exposure. Additionally, questions were asked regarding PMMA training and whether beliefs influenced specialty choices. Results. There were 278 survey responses received, of which 256 met inclusion criteria. 73% currently utilize PMMA in training/practice, and >90% of survey respondents reported awareness of risks surrounding PMMA in pregnancy. PMMA training was found to have a weak positive correlation with those who remained in the room while pregnant. 43.6% would leave the room in the future if PMMA were being used while they were pregnant, with 26.2% leaving if they were breastfeeding. 24.9% would leave if they were the primary surgeon on the case, and 8.4% admitted that PMMA exposure during pregnancy factored into which subspecialty they chose. Conclusion. This survey demonstrates a lack of consensus amongst female orthopedic surgeons regarding the risks posed by remaining in a room during pregnancy and breastfeeding while PMMA is used. Despite 90% of respondents claiming awareness of the risks of PMMA, beliefs and education practices should be examined to determine if they match the available literature. It is plausible that beliefs regarding this exposure are deterring individuals from pursuing specialties where PMMA is used regularly. For any tables or figures, please contact the authors directly

Traumatic acute or chronic tendon injuries are a wide clinical problem in modern society, resulting in important economic burden to the health system and poor quality of life in patients. Due to the low cellularity and vascularity of tendon tissue the repair process is slow and inefficient, resulting in mechanically, structurally, and functionally inferior tissue. Tissue engineering and regenerative medicine are promising alternatives to the natural healing process for tendon repair, especially in the reconstruction of large damaged tissues. The aim of TRITONE project is to develop a smart, bioactive implantable 3D printed scaffold, able to reproduce the structural and functional properties of human tendon, using FDA approved materials and starting from MSC and their precursor, MPC cell mixtures from human donors. Total cohort selected in the last 12 months was divided in group 1 (N=20) of subjects with tendon injury and group 2 (N=20) of healthy subject. Groups were profiled and age and gender matched. Inclusion criteria were age>18 years and presence of informed consent. Ongoing pregnancy, antihypertensive treatment, cardiovascular diseases, ongoing treatment with anti-aggregants, acetylsalicylic-acid or lithium and age<18 years were exclusion criteria. Firstly, we defined clinical, biological, nutritional life style and genetic profile of the cohort. The deficiency of certain nutrients and sex hormonal differences were correlated with tendon-injured patients. It was established the optimal amount of MPC/MSC human cell (collected from different patients during femoral neck osteotomy). Finally, most suitable biomaterials for tendon regeneration and polymer tendon-like structure were identified. Hyaluronic acid, chemical surface and soft-molecular imprinting (SOFT-MI) was used to functionalize the scaffold. These preliminary results are promising. It will be necessary to enroll many more patients to identify genetic status connected with the onset of tendinopathy. The functional and structural characterization of smart bioactive tendon in dynamic environment will represent the next project step

Introduction. Congenital scoliosis is a prevalent congenital spinal deformity, more frequently encountered than congenital lordosis or kyphosis. The prevailing belief is that most instances of congenital scoliosis are not hereditary but rather stem from issues in fetal spine development occurring between the 5th and 8th weeks of pregnancy. However, it has been linked to several genes in current literature. Our goal was to explore potential pathways through an exhaustive bioinformatics analysis of genes related to congenital scoliosis. Method. The literature from the 1970s to February 2024 was surveyed for genes associated with CS, and 63 genes were found to be associated with AIS out of 1743 results. These genes were analyzed using DAVID Bioinformatics. Result. Our pathway analysis has unveiled several significant associations with congenital scoliosis. Notably, “Glycosaminoglycan biosynthesis - chondroitin sulfate / dermatan sulfate” (P-Value:8.8E-3, Fold Enrichment: 20.6), “Central carbon metabolism in cancer” (P-Value:1.3E-3, Fold Enrichment: 10.3), and “Lysine degradation” (P-Value: 9.0E-3, Fold Enrichment: 9.1) emerge as statistically significant pathways. Additionally, “Endocrine resistance” (P-Value:4.4E-3, Fold Enrichment:7.4) and”EGFR tyrosine kinase inhibitor resistance” (P-Value: 1.7E-2, Fold Enrichment:7.3) pathways are noteworthy. These findings suggest a potential involvement of these pathways in the biological processes underlying congenital scoliosis. Furthermore, “Signaling pathways regulating pluripotency of stem cells” (P-Value:4.0E-4, Fold Enrichment:7.1), “Notch signaling pathway” (P-Value:6.7E-2, Fold Enrichment: 7.0), and “TGF-beta signaling pathway” (P-Value:6.2E-3, Fold Enrichment: 6.7) exhibit a less pronounced yet intriguing association that may warrant further investigation. Conclusion. In conclusion, our comprehensive analysis of the genetic etiology of congenital scoliosis has revealed significant associations with various pathways, shedding light on potential underlying biological mechanisms.
