Incidence and risk factors of symptomatic peripartum diastasis of pubic symphysis

Postpartum pubic symphysis diastasis resulting in a prepubic abscess and osteomyelitis

Postpartum pubic symphysis diastasis (PSD) refers to an abnormal widening of the pubic symphysis after delivery. It is a rare and underdiagnosed condition that causes severe pain and can be complicated by osteomyelitis and abscess formation. This article reports a case of a para 4 woman in her 30s with postpartum PSD after vaginal delivery who presented with a prepubic abscess. Multimodal treatment consisted of incision and drainage, physiotherapy and prolonged antibiotic treatment.

Postpartum Pelvic Instability: A Case Report

Pubic symphysis diastasis following childbirth is a rare orthopedic condition that can be debilitating in the postpartum period. There have been treatment options documented, ranging from conservative to surgical; however, no standard of care has been established. We present a 44-year-old female patient who underwent open reduction and internal fixation for continued instability from postpartum pubic symphysis diastasis with a good overall outcome. We demonstrate good outcomes in a patient treated with surgical fixation of postpartum pelvic diastasis. We hope to deliver insight to future orthopedic surgeons with the challenges in treating this condition.

Clinical Presentation and Management of Peripartum Pubic Diastasis

Background

Symphysis pubis diastasis (SPD) is an uncommon peripartum complication which can have short-term morbidities secondary to pain and restricted movements as well as long-term complications. It is important to diagnose this condition as it causes significant discomfort to the nursing mothers. We present our experience in five patients with SPD who were managed successfully.

Methods

Present study is an observation of five cases of SPD managed in a single unit in a tertiary care center over three years from January 2017 to December 2019. All women with symptoms of SPD with inter-pubic distance of more than 10 mm were selected for the study. The demographic profile, clinical details, diagnostic imaging findings, and treatment provided for such patients were noted down from the individual case records. Follow-up of each patient for improvement in the symptoms and X-ray findings was available till 3 months for each case.

Results

Mean age of the women with SPD was 29.8 ± 5.4 years. Four women had vaginal delivery and one had vacuum delivery. Average birth weight is 3.26 ± 0.85 kg. Mean duration of first stage of labor is 6.6 ± 0.89 h and median of second stage is 35 min. Average inter-pubic distance at the time of diagnosis on X-ray was 1.84 ± 0.2 cm. All women were managed conservatively with bed rest, analgesics, pelvic binder and physiotherapy. Improvement in the range of movement was noted over average of 21.8 ± 3.7 days and symptoms resolved over 14.4 ± 2.6 weeks.

Conclusion

Treating obstetrician should be aware of this condition as simple treatment measures can avoid the long-term morbidities and complications.

Pubic Symphysis Separation and Regression in Vaginal versus Cesarean Delivery

OBJECTIVE

To quantify the association of pubic symphysis separation with mode of delivery and follow the resolution of this physiologic separation in the postpartum period.

METHODS

Prospective observational cohort study that recruited two cohorts of primiparous women: those undergoing vaginal and cesarean delivery (45 and 46 patients, respectively). Chart review collected intrapartum factors. Patients were followed with serial anterior-posterior radiographs within 48 hours of delivery and at 6, 12, and 24 weeks postpartum, to evaluate the extent of pubic symphysis separation. Differences between the two cohorts in intrapartum factors were assesses as was pubic symphysis separation at each time point.

RESULTS

Mean age of women was 25.8 (SD 5.1) years, and 56% were White. Mean birth weight was 3.5 (SD 0.52) kg. Mean immediate postpartum pubic symphysis separation was 7.6 (SD 2.2) mm and did not differ between groups, at 7.18 mm for vaginal delivery versus 8.04 mm for cesarean delivery (CD; P = 0.08). Pubic symphysis separation was not significantly different for CD with and without labour. Black race and obesity were associated with increased pubic symphysis separation. No intrapartum events were related to extent of separation. Normalization of pregnancy pubic symphysis separation to 4-5 mm occurred by 6 weeks postpartum. Separation of >10mm and <15mm occurred in 10 of the 91 women and occurred after vaginal and cesarean delivery. The widest pubic symphysis separation was observed in 3 patients after vaginal delivery.

CONCLUSION

Physiological pubic symphysis separation occurs during pregnancy and regresses postpartum with minimal effects from labour and delivery. Cesarean delivery does not prevent physiological pubic symphysis separation.

Chronic Pelvic Diastasis 22 Years After Twin Natural Delivery: A Case Report

CASE

We present here a case of chronic pelvic separation 22 years after twin natural delivery in a 49-year-old woman surgically treated with anterior and posterior stabilization. The functional and radiological recovery after a 4-year follow-up was extremely good.

CONCLUSION

Postpartum pubic symphysis diastasis is a rare but dreaded complication of natural delivery. Nonoperative treatment is still considered the gold standard. However, when pain persists despite nonoperative treatment and when a pelvic radiograph reveals a pubic diastasis greater than 2 cm, surgery is recommended. In the case of low back pain because of sacroiliac joint lesions, posterior fixation is indicated.

Peripartum Pubic Symphysis Diastasis-Practical Guidelines

Optimal development of a fetus is made possible due to a lot of adaptive changes in the woman’s body. Some of the most important modifications occur in the musculoskeletal system. At the time of childbirth, natural widening of the pubic symphysis and the sacroiliac joints occur. Those changes are often reversible after childbirth. Peripartum pubic symphysis separation is a relatively rare disease and there is no homogeneous approach to treatment. The paper presents the current standards of diagnosis and treatment of pubic diastasis based on orthopedic and gynecological indications.

A case-control study of clinical characteristics and risk factors of symptomatic postpartum pubic symphysis diastasis

Postpartum pubic symphysis diastasis (PPSD) refers to the separation of pubic symphysis after delivery. It is typically diagnosed based on clinical symptoms and radiologic findings. This study tried to assess clinical characteristics and risk factors of PPSD. This was a nested case-control study matched for year of delivery and gestational age at delivery using a retrospective cohort of women who delivered vaginally at a single institution. The incidence of PPSD was 0.156% (33/21,131). The incidence rate increased from 0.08% (7/9328) in 2000-2004 to 0.13% (9/7138) in 2005-2009 and to 0.36% (17/4665) in 2010-2016, simultaneously with an increase of maternal age (30.7 ± 3.5 years in 2000-2004 to 31.8 ± 3.8 years in 2005-2009 and 32.8 ± 3.8 years in 2010-2016). Nulliparity was associated with a higher incidence of PPSD (81.8% in cases vs. 57.6% in controls, p = 0.01). Other factors including pre-pregnancy body mass index, weight gain during pregnancy, gestational diabetes, induction of labor, duration of labor, epidural anesthesia, vacuum-assisted delivery, episiotomy, neonatal sex and birth weight failed to show difference between the two groups. In short, the incidence of PPSD increased with time along with an increase of maternal age. Nulliparity was the only significant risk factor for PPSD.

Role of relaxin in diastasis of the pubic symphysis peripartum

BACKGROUND

Separation of the pubic symphysis can occur during the peripartum period. Relaxin (RLX) is a hormone primarily secreted by the corpus luteum that can mediate hemodynamic changes during pregnancy as well as loosen the pelvic ligaments. However, it is unknown whether RLX is associated with peripartum pubic symphysis separation and if the association is affected by other factors.

AIM

To study the association between RLX and peripartum pubic symphysis separation and evaluate other factors that might affect this association.

METHODS

We performed a cross-sectional study of pregnant women between April 2019 and January 2020. Baseline demographic characteristics, including gestational age, weight, neonatal weight, delivery mode and duration of the first and second stages of labor, were recorded. The clinical symptoms were used as a screening index during pregnancy, and the patients with pubic symphysis and inguinal pain were examined by color Doppler ultrasonography to determine whether there was pubic symphysis separation. Serum RLX concentrations were evaluated 1 d after delivery using an enzyme-linked immunosorbent assay, and pubic symphysis separation was diagnosed based on postpartum X-ray examination. We used an independent-sample t test to analyze the association between serum RLX levels and peripartum pubic symphysis separation. Multivariate regression analysis was used to evaluate whether the association between RLX and peripartum pubic symphysis separation was confounded by other factors, and the association between RLX and the severity of pubic symphysis separation was also assessed. We used Pearson correlation analysis to determine the factors related to RLX levels as well as the correlation between the degree of pubic symphysis separation and activities of daily living (ADL) and pain.

RESULTS

A total of 54 women were enrolled in the study, with 15 exhibiting (observational group) and 39 not exhibiting (control group) peripartum pubic symphysis separation. There were no statistically significant differences in terms of maternal age, gestational age, pre-pregnancy weight, weight gain during pregnancy, delivery modes, or duration of the first or second stages of labor between the 2 groups. We did, however, note a statistically significant difference in serum RLX concentrations and neonatal weight between the observational and control groups (122.3 ± 0.7 µg/mL vs 170.4 ± 42.3 µg/mL, P < 0.05; 3676.000 ± 521.725 g vs 3379.487 ± 402.420 g, P < 0.05, respectively). Multivariate regression analyses showed that serum RLX level [odds ratio (OR): 1.022) and neonatal weight (OR: 1.002) were associated with pubic symphysis separation peripartum. The degree of separation of the pubic symphysis was negatively correlated with ADL and positively correlated with pain. There was no statistically significant association between serum RLX levels and the severity of pubic symphysis separation after adjusting for confounding factors.

CONCLUSION

Serum RLX levels and neonatal weight were associated with the occurrence, but not the severity, of peripartum pubic symphysis separation.

Postpartum pubic symphysis diastasis-conservative and surgical treatment methods, incidence of complications: Two case reports and a review of the literature

BACKGROUND

Widening of the pubic joint of more than 10 mm is diagnostic and defined as pubic symphysis diastasis and is considered a complication of vaginal childbirth or pregnancy. As it is a rare pathology (ranging from 1 in 300 to 1 in 30000 pregnancies), no gold standard treatment has been defined.

CASE SUMMARY

This study examines two cases, a 27-year-old woman (gravida 1, para 1) and a 32-year-old woman (gravida 2, para 2), who presented to the clinic after uneventful vaginal deliveries. A normal pregnancy with no complications was observed in both patients. Severe pain in the pubic region occurred after labour and was accompanied by complicated locomotion. Pubic symphysis diastasis was confirmed radiologically and bed rest with lateral decubitus positioning was recommended. Oral non-steroidal antiinflammatory drugs were administered to relieve pain exacerbations. The symptoms decreased after treatment. Post-treatment magnetic resonance imaging (MRI) in the first case showed a reduction in symphyseal separation with no signs of osteitis. Three years later the symptoms recurred; MRI examination showed no further symphyseal widening or signs of osteitis. A relapse of symphyseal separation was diagnosed and conservative treatment was re-administered resulting in successful recovery. In the second case, pain recurred when the patient conceived for the second time. This time no benefit following conservative treatment was observed. Persistent pain and complicated locomotion led to scoliotic deformation of the lumbar part of the spine and leg length discrepancy, thus surgical treatment was chosen and internal pubic synthesis was performed.

CONCLUSION

Overall, surgical treatment resulting from insufficient conservative treatment showed a high risk of postoperative complications following the treatment of postpartum pubic symphysis diastasis.

Traumatic Pelvic Ring Injury following Childbirth with Complete Pubic Symphysis Diastasis

Case

Traumatic pelvic ring injury following childbirth is a rare but debilitating condition. We present a case of a 28-year-old female who sustained a traumatic pelvic ring injury following childbirth with a complete pubic symphysis separation of 5.6 cm treated successfully with nonoperative management.

Conclusion

Operative and nonoperative treatments for traumatic pelvic ring injuries following childbirth have been described without universal adoption of a uniform treatment modality. We hope this case study adds to the collection of data to help guide medical decision-making in the future as surgeons encounter patients with similar orthopedic injuries.

Separación de la sínfisis púbica postparto

La separación de la sínfisis púbica después del parto vaginal normal es rara. La etiología no es clara y se asocia con multiparidad, macrosomía, debilitamiento fisiológico de la articulación y fuerza excesiva en el área púbica. Los síntomas incluyen dolor cerca de la articulación púbica, caderas, ingle, región inferior del abdomen y parte interna de los muslos, acompañado de sensibilidad del área. Los estudios con imágenes muestran la distancia entre los huesos púbicos. El manejo médico es variable y los resultados potenciales todavía son poco comprendidos. El retraso en el diagnóstico tiene graves consecuencias para la salud de la mujer en forma aguda y a largo plazo. Se presenta una paciente de 18 años con dolor lacerante en el área púbica durante el segundo día del puerperio. Tenía antecedentes de embarazo de evolución normal y parto vaginal espontáneo, a término, con recién nacido vivo y sin complicaciones. En el examen físico había dolor moderado en la región del pubis que interfería con la marcha y los movimientos activos de ambos miembros inferiores. La radiografía pélvica anteroposterior en posición supina mostró separación anormal de la sínfisis púbica de aproximadamente 25 milímetros de extensión, sin otras anomalías óseas o congénitas. Se recomendó tratamiento conservador con recuperación a los 3 meses.

Pubic Symphysis Diastasis: A Case Series and Literature Review

Separation of pubic symphysis during delivery is a rare complication resulting in considerable and prolonged morbidity for parturient women. The usual presentation is that of something giving way in the region of the symphysis pubis sometimes with an audible crack at the time of delivery. Unbearable pain on moving from side-to-side and on performing any weight-bearing activity (such as walking or climbing stairs) precludes ambulation in the immediate postpartum period. This could be accompanied by disruption of the sacroiliac joint, hemorrhage, or urine incontinence in severe cases. Radiography, ultrasound, and magnetic resonance imaging are the diagnostic modalities that aid confirmation of diagnosis. The magnitude of separation does not correlate well with the severity of symptoms. Treatment modalities range from conservative management (including analgesics, pelvic binders, transcutaneous nerve stimulation) and chiropractic management to orthopedic interventions such as external fixation or open reduction and internal fixation. Since postpartum pain is frequently dismissed as attributable to labor and childbirth, the diagnosis of pubic symphysis diastasis is often delayed and sometimes missed altogether. Since there is no consensus in the scientific literature on the definition, etiopathogenesis, and management of this rare complication, we attempted to review the literature on the subject and present a series of two cases.

Acute Intrapartum Rupture of the Pubic Symphysis Requiring Resuscitation and Surgical Intervention: A Case Report

BACKGROUND

Pubic symphysis rupture significant enough to cause serious complications or require surgical intervention is exceedingly rare. Here we review the literature and examine the details of a unique presentation.

CASE

A 27-year-old woman presented in labour at 34+6 weeks gestation after an uncomplicated monochorionic-diamniotic twin pregnancy. After vaginal delivery, she developed a substantial labial hematoma. Hours later, she became hemodynamically unstable. Imaging revealed a 4.7-cm pubic diastasis and a small arterial tear. One week later, the diastasis had expanded to 6 cm on X-ray. As a result, the patient underwent surgical intervention. She was discharged home on postpartum day 21 and remained non-weight-bearing for 8 weeks.

CONCLUSION

Pubic symphysis rupture is a potentially life-threatening obstetrical complication that requires early recognition and effective multidisciplinary care.

Outcome of Internal Fixation and Corticocancellous Grafting of Symphysis Pubis Diastasis Which Developed after Malunion of Pubic Rami Fracture

We report a case of pubic symphysis diastasis, which was initially asymptomatic; however, it became symptomatic with urinary incontinence during pregnancy. The patient was treated with open reduction and internal fixation of the symphysis pubis. A corticocancellous autograft was used for filling the gap which remained despite bilateral compression of the iliac bones. We obtained satisfactory outcome in terms of symptoms at the 3 years' follow-up; however, there was instability findings in the X-rays with broken screws. We conclude that asymptomatic pubic symphysis diastasis might be symptomatic after additional trauma (such as pregnancy) in the following days, if it was unstable in the very beginning of injury. Fixation of old pubic symphysis diastasis with reconstruction plate by filling the gap by using corticocancellous autograft, might not prevent ultimate implant failure if the symphysis pubis diastasis is part of an unstable pelvic fracture in the very beginning.

Management of Postpartum Diastasis of the Pubic Symphysis

Conservative management is typically recommended for postpartum diastasis of the pubic symphysis, despite significant functional disability and chronic pain associated with this condition. With a reported incidence of 1:500, the authors describe diagnosis and management controversies with an additional review of relevant literature related to the management of this orthopedic condition. The case is of a 27-year-old woman diagnosed with 5.5-cm diastasis of the pubic symphysis after spontaneous vaginal delivery of a 5 lb 5 oz infant. She underwent early orthopedic surgical correction via open reduction and internal fixation. The patient achieved pain-free ambulation within 3 months of surgery, and returned to full activity at 6 months. Postpartum diastasis of the pubic symphysis is typically treated conservatively; however, the authors illustrate that early orthopedic consultation and intervention at diastasis greater than 5 cm may improve recovery and functional outcome.

Pubic Symphysis Rupture and Separation During Pregnancy

OBJECTIVE

The aim of this study was to determine the risk factors, clinical and radiologic criteria for diagnosis, and management of this unusual complication of pregnancy.

METHODS

A PubMed and Web of Science search was undertaken with no limitations on the number of years searched.

RESULTS

There were 36 publications identified, with 19 articles being the basis of this review. Multiple risk factors have been identified including multiparity, macrosomia, cephalopelvic disproportion, forceps deliveries, precipitous labor, malpresentation, prior pelvic trauma, and use of the McRoberts maneuver. The diagnosis is usually made clinically, confirmed by imaging, and considered pathological when the intrapubic gap is greater than 10 mm. Magnetic resonance imaging appears to be superior to pelvic x-ray and computed tomography scan in visualization of the bone separation. Conservative treatment remains the first choice for therapy, but women who do not respond to conservative therapy or women with large separations may need surgical stabilization with external or internal fixation.

CONCLUSIONS

Widening of the pubic symphysis greater than 10 mm is pathologic. The diagnosis is clinical and confirmed by imaging studies, with magnetic resonance imaging being the superior technique. Conservative treatment is the first line of therapy. Failure of conservative therapy is treated by surgical stabilization.

Diastasis of symphysis pubis and labor: Systematic review

Symphysis pubis diastasis (SPD) is an infrequent complication of labor that can impair womens' general health through failure of the passive stability of the pelvic girdle. Although conservative approaches are often used to decrease symptoms and interpubic separation, notably few studies have analyzed the effect of these methods on managing the symptoms of women with SPD. The purpose of this study was to review the available literature on the conservative treatment of SPD during pregnancy and labor. A computer-based search using PubMed, PEDro, and CINAHL was performed up to November 2014. We selected all studies that considered women with SPD during pregnancy or labor and treated them with conservative methods and excluded those that included surgical intervention. Eighteen studies were selected, most of which were case reports. Although the overall results of conservative treatment were unclear because of the type and design of the obtained studies, most of the studies reported bed rest in the lateral decubitus position and a pelvic girdle as basic treatments. Additionally, the few clinical trials reported recommended additional physiotherapy, including strengthening and stabilizing exercises, to reduce SPD symptoms.

The Irish experience of Symphysiotomy: 40 years onwards

The art of symphysiotomy for delivery in the instance of cephalopelvic disproportion has been a dying art since the advent of caesarean section but in Ireland this surgical procedure was not abolished until 1992. This practice is still present in the developing world and in some circumstances used in developed countries. This study offers some insights on the 40-year follow-up of patients who had undergone symphysiotomy.
