[Research progress of pubic symphysis diastasis].

Objective: To review the research progress of pubic symphysis diastasis and provide effective reference for orthopedic surgeons in the diagnosis and treatment of pubic symphysis diastasis. Methods: The anatomy, injury mechanism, treatment, and other aspects of pubic symphysis diastasis were summarized and analyzed by reviewing the relevant research literature at domestically and internationally in recent years. Results: The incidence of pubic symphysis diastasis is high in pelvic fractures, which is caused by the injury of the ligaments and fibrocartilage disc around the pubic symphysis by external force. The treatment plan should be individualized according to the pelvic stability and the needs of patients, aiming to restore the stability and integrity of the pelvis and improve the quality of life of patients after surgery. Conclusion: At present, the research on pubic symphysis diastasis still needs to be improved. In the future, high-quality, multi-center, and large-sample studies are of great significance for the selection of treatment methods and the evaluation of effectiveness for patients with pubic symphysis diastasis.

Postpartum Symphysis Pubis Diastasis: A Case Report.

The pubic symphysis is a midline, non-synovial joint connecting the right and left superior pubic rami. The joint allows very limited movement of approximately 0.5-1 mm. Under hormonal stimulation during pregnancy, the widening of the symphysis pubis and sacroiliac joints occurs. Pubic symphysis diastasis is defined as the widening of the pubic joint of >10 mm. It is a rare complication of vaginal childbirth for which no gold standard treatment has been defined. Most cases are treated conservatively. A case of pubic diastasis in a 24-year-old G5P2A2L1 following vaginal delivery is reported. Management consisted of simple conservative treatment, which was sufficient in achieving symptomatic relief. Keywords: case reports; pelvic pain; pubic symphysis diastasis.

Evaluation of symphysis pubis and sacroiliac joint distances in skeletally immature patients: A computerized tomography study of 1020 individuals.

OBJECTIVE: The aim of this study was to create a reference about normal pubic symphysis and sacroiliac joint widths of children and adolescents. METHODS: A total of 1020 computerized tomography axial scans of patients without pelvic injury between 2 and 18 year-old were studied. The narrowest width of pubic symphysis and bilateral sacroiliac joints were measured. RESULTS: The average pubic symphyseal width at 2 years old boys was 6.35 ± 1.06 mm (4.88-9.13 mm). The average of right and left sacroiliac joints' widths at 2 years old boys was 4.56 ± 0.65 mm (3.59-6.07 mm) and 4.58 ± 0.66 mm (3.44-5.74 mm), respectively. The average pubic symphyseal width of 2 years old girls was 5.85 ± 1.14 mm (4.06-8.20 mm). The average of right and left sacroiliac joints' widths at 2 years old girls was found 4.36 ± 0.56 mm (3.50-5.37 mm) and 4.42 ± 0.59 mm (3.58-5.73 mm), respectively. The average pubic symphyseal width at 18 years old boys was found 3.68 ± 1.30 mm (1.90-5.79 mm). The average of right and left sacroiliac joints' widths at 18 years old boys was found 1.97 ± 0.21 mm (1.73-2.41 mm) and 2.04 ± 0.30 mm (1.70-2.65 mm), respectively. The average pubic symphyseal width at 18 years old girls was 3.92 ± 0.52 mm (2.97-4.76 mm). The average of right and left sacroiliac joints' widths at 18 years old girls was found 2.34 ± 0.40 mm (1.58-3.34 mm) and 2.33 ± 0.37 mm (1.58-3.10 mm), respectively. CONCLUSION: Our results suggest that one should be suspicious about pelvic injury if the width of pubic symphysis is over 10 mm and width of sacroiliac joint is over 8 mm especially in patients younger than 10 years-old. LEVEL OF EVIDENCE: Level III Diagnostic study.

Post-partum management of severe pubic diastasis.

INTRODUCTION: Pubic symphysis diastasis during pregnancy is a rare complication which can present as pain with ambulation, urinary dysfunction, and pelvic instability. A consensus treatment does not currently exist between surgical and conservative management. The authors present a case of severe pubic diastasis which was successfully treated using a conservative pelvic binder. CASE REPORT: A 31-year-old female presented with severe lower back pain following the uneventful delivery of her fourth child. On radiograph, a pubic symphysis diastasis of 5.5 cm was noted and she was subsequently fitted with a pelvic binder on post-partum day 3. She experienced a full range of motion and was pain free at six-week follow-up, with a diastasis of 2.1 cm present. At one year and three-month follow-up, the patient presented with a diastasis of 2.4 cm and continued to have full range of motion and mobility. CONCLUSION: This case contributes to the literature in showing that conservative treatment of pubic diastasis could be considered in cases where separation has exceeded normal physiologic limits.

Computed tomography-based three-dimensional visualisation of bone corridors and trajectories for screws in open reduction and internal fixation of symphysis diastasis: a retrospective radiological study.

INTRODUCTION: Typical stabilisation of pelvic open book injuries consists of plate fixation of the symphysis. No previous literature has been published about the evaluation of screw placement and their trajectory with four oblique 4.5 mm screws using a four-hole plate in symphysis diastasis. The aim of this study was to define insertion points and angles of trajectory for crossed screw placement regardless of any plate design based on an analysis of three-dimensional computed tomography data sets. METHODS: One hundred human pelvic CT data sets were collected. Unilateral and bilateral placements of crossed 4.5 mm screws were simulated. Primary outcome measure was successful simulated screw placement without cortical breach. Secondary outcome measures included the anatomical measurements of the screw positions. RESULTS: Simulated screw placement of two oblique screws on each side of the pubic symphysis without cortical breach was achieved in all (100 %) cases. There were a total of 400 screw simulations. Medial screws were longer, lateral screws had higher coronal angles, and the distance between both screws was higher on the right side (p < 0.001 each). The lengths of the right lateral, right medial, left lateral, and left medial screws were 44.9, 65.8, 45.4, and 67.4 mm, respectively. The sagittal angles to the dorsal surface area of the pubic rami were 10.5°, 11.1°, 9.0°, and 11.0°. The coronal angles to the vertical axis of the symphysis measured 39.5°, 16.0°, 33.8°, and 16.8°. The distances between these screws and the medial edge of the pubic crest were 33.5, 8.6, 29.5, and 7.3 mm. Furthermore, certain sex- and side-related differences were noted. CONCLUSIONS: This series provides results about the feasibility and a detailed anatomical description of crossed screw placement. This is of special interest in pelvic surgery for choosing the entry points, safe screw channel parameters, and trajectories.

Peripartum pubic symphysis separation--Current strategies in diagnosis and therapy and presentation of two cases.

BACKGROUND: During spontaneous vaginal delivery, pubic symphyseal widening is normal. Common changes are reversible after complication-free birth. However, cases of peripartum symphysis separation are rare. There is no consensus in the literature on how to treat pregnancy-related pubic symphysis separation. METHODS: This review used a literature-based search (PubMed, 1900-2013) and analysis of 2 own case reports. Studies with conclusions regarding management were particularly considered. RESULTS: Characteristic symptoms, suprapubic pain and tenderness radiating to the posterior pelvic girdle or lower back, may be noted 48 h after delivery. Pain on movement, especially walking or climbing stairs, is often present. Conservative treatments, such as a pelvic brace with physiotherapy and local interventions such as infiltration, are successful in most cases. Symptom reduction within 6 weeks is the most common outcome, but can take up to 6 months in some cases. Surgical intervention is needed in cases of persistent separation. Anterior plate fixation is offered as a well-known and safe procedure. Minimally invasive SI joint screw fixation is required in cases of combined posterior pelvic girdle lesions. SUMMARY: Postpartum symphyseal rupture can be indicated with the rare occurrence of pelvic pain post-delivery, with sciatica or lumbago and decreased mobility. The diagnosis is made on clinical findings, as well as radiographs of the pelvic girdle. Conservative treatment with a pelvic brace is the gold standard in pre- and postpartum cases of symphysis dysfunction.

Incidence and risk factors of symptomatic peripartum diastasis of pubic symphysis.

This study was undertaken to determine incidence, associated risk factors, and clinical outcomes of a diastasis of pubic symphysis. Among 4,151 women, who delivered 4,554 babies at the Department of Obstetrics of Seoul National University Bundang hospital from January 2004 to December 2006, eleven women were diagnosed as having a symptomatic diastasis of pubic symphysis. We estimated the incidence of the diastasis and identified the associated risk factors. To evaluate the pain relief and reduction of diastasis we followed up the 11 diastatic patients. The incidence of the diastasis was 1/385. Primiparity (P = 0.010) and twin gestation (P = 0.016) appeared as risk factors for diastasis by univairable analysis; and twin gestation appeared to be the only risk factor (P = 0.006) by logistic analysis. Two patients were operated due to intractable pain; and the remaining nine patients were treated conservatively. The diastatic gap decreased to less than 1.5 cm by 2 to 6 weeks after the diagnosis and then remained stationary. At a mean follow-up of 22.1 months (range, 12 to 47 months), five of 11 patients had persistent symphysis pubis dysfunction. Diastasis is more frequent than generally acknowledged. Pregnant women with multiple gestations should be informed about the potential risk of pubic symphysis diastasis.

Isolated anterior unilateral sacroiliac dislocation without pubic arch disjunction.

Sacroiliac joint dislocations frequently occur in a context of high-energy polytrauma. When there is disruption of the pelvic ring, sacroiliac joint displacements are more often posterior and combine two lesions: either lesions of the pubic arch as well as the posterior arch or bilateral lesions. The case we report here lacks these two characteristics. This is an isolated unilateral sacroiliac dislocation with no opening lesion of the pubic symphysis or fracture of ilio- or ischiopubic rami and with anterosuperior displacement. After emergency reduction of the dislocation, the secondary fixation was not performed, due to initial hemodynamic instability compounded by deteriorating central nervous system condition.

Case report: Physiotherapy strategies for a woman with symphysis pubis diastasis occurring during labour.

This case report demonstrates a therapeutic exercise program as a noninvasive functional treatment for symphysis pubis diastasis (SPD) and reports its results. A 32-year-old primigravida with SPD during labour received a specific functional exercise program, which consisted of abdominal stabilization and strengthening of the pelvic floor muscles, hip adductors, and extensors; training for bed mobility; and walking training with suitable aids. The program was performed for 1-hour per session, twice a day, for 2 weeks. Before the intervention, the patient was totally dependent on others for performing her daily activities owing to severe pain in the pelvic region. After the 2-week intervention, however, the interpubic distance was reduced by 36% (from 22 mm to 14 mm), and pain and functional disability were remarkably improved. Moreover, the patient could walk independently for 30 m with a pelvic corset. Our results suggest that a systematically designed functional rehabilitation program may be beneficial in the functional recovery of patients suffering from SPD related to pregnancy.

Peripartum pubic symphysis separation: a case report and review of the literature.

UNLABELLED: Although peripartum pubic symphysis diastasis is an uncommon complication of delivery, it can lead to considerable and sometimes long-term disability. Although the initial clinical examination and diagnostic workup for this complication are relatively straightforward, the best treatment for a peripartum pubic symphysis diastasis is less clear. Historically, nearly all women were treated conservatively with bed rest and pelvic binders. However, more recent case reports have described more invasive orthopedic procedures being used to help speedy recovery. In this study, we present a case of a 22-year-old primigravida who had a severe pubic symphysis separation after a vaginal delivery complicated by a shoulder dystocia. We also reviewed the literature on this topic over the past 20 years to gain a better understanding of the clinical factors surrounding peripartum pubic symphysis separation and the treatment option available to women with this complication. TARGET AUDIENCE: Obstetricians & Gynecologists. LEARNING OBJECTIVES: After completing this CME activity, physicians should be better able to identify the clinical factors that associated with peripartum pubic symphysis separation; perform a diagnostic workup when a peripartum pubic symphysis separation is suspected; distinguish the conservative and invasive orthopedic interventions available for the treatment of peripartum pubic symphysis separation; and show that the degree of patient disability after peripartum pubic symphysis separation varies greatly and no clinical factors or diagnostic studies effectively predict the course of patient recovery.

Severe separation of the pubic symphysis and prompt orthopedic surgical intervention.

BACKGROUND: The incidence of pubic symphysis separation during delivery is 1 in 300 to 1 in 30,000 pregnancies, and it can cause a variety of problems such as pain, bladder dysfunction, and difficulty ambulating. There is no consensus on how to treat pregnancy-related pubic symphyseal separation. CASE: A patient, gravida 1 para 1, who underwent vacuum-assisted vaginal delivery was found to have a severe vaginal sidewall laceration and a 6.2-cm symphyseal disruption. The patient was treated with external fixation of an open book pelvis and physical therapy. She was discharged to home on postpartum day 4, voiding spontaneously and ambulatory with a walker. CONCLUSION: Aggressive treatment of severe pubic symphysis separation with external fixation resulted in early ability to ambulate, void, and care for self and baby.

Risk factors for erectile dysfunction in patients with urethral strictures secondary to blunt trauma.

INTRODUCTION: Erectile dysfunction (ED) is a well-known consequence of pelvic fracture, particularly in cases involving urethral injury. There are several risk factors that may be related to ED. However, no systemic approach is used to assess erectile function secondary to urethral trauma. AIM: To investigate ED associated with urethral injury secondary to pelvic fracture and perineal trauma. METHODS: Forty patients with traumatic urethral strictures secondary to blunt traumatic impact episode to the pelvis or perineum were included in our study. Pelvic fractures and urethral strictures were categorized according to injury types and radiological findings. All patients underwent nocturnal penile tumescence (NPT) monitoring, dynamic color-duplex Doppler ultrasonography (D-CDDU) before surgery. NPT monitoring was conducted again after surgery. MAIN OUTCOME MEASURES: The events of NPT and D-CDDU were recorded. RESULTS: In all patients, 11 had organic ED demonstrated by NPT. Vascular pathology was identified in three of 11 patients (27%). The peak systolic velocity of cavernosal artery was lower in patients with pubic diastasis in comparison to those without diastasis (P < 0.05). Significant changes in penile length and circumference were noted in posterior urethral injury compared with anterior urethral injury during erection (P < 0.05). The erectile duration time has a similar statistical difference in two groups mentioned above. However, no significant difference could be observed in the end-to-end anatomosis procedure before and after surgery (P > 0.05). CONCLUSIONS: The pelvic fracture type, especially pubic diastasis, is a risk factor for ED following urethral injury. Location of the stricture is also a risk factor for subsequent erectile dysfunction.

Symphysial pelvic dysfunction.

PURPOSE OF REVIEW: Symphysial pelvic dysfunction is a condition which develops during pregnancy and may lead to significant morbidity affecting quality of life. While postpartum resolution is common, symptoms may persist for many years. The consequences, specifically disabling pain, are even more detrimental on mothers with a young family. This review summarizes current understanding of the condition, including pathogenesis, risk factors and management. RECENT FINDINGS: There is no current international consensus on definition, diagnostic criteria, and treatment protocols for symphysial pelvic dysfunction. Discrepancy between the reported rates of prevalence stems from ambiguity in definition and inclusion criteria in reported studies. The pathogenesis of the condition is still unclear although numerous theories have been proposed. It is likely to be multifactorial in origin with multiple factors both biomechanical and genetic factors playing an important role. There is also a paucity of information in the literature about the best management strategy. SUMMARY: There is an urgent need to standardize terminology and define diagnostic criteria for symphysial pelvic dysfunction in order to improve the management and better understand the pathophysiology of this condition.

Post partum diastasis of the pubic symphysis: a case report.

The post partum pubic symphysis diastasis is an uncommon disease. It is resposible of acute pelvic pain. It increases when manual pressure is applied to the pelvis in a latero-lateral and antero-posterior direction. The diagnostic test for this condition is an anteroposterior X-ray of the pelvis. Here we present a case following spontaneous vaginal delivery. The conservative treatment is able to obtain good results. If this disease is underestimated the patient can develop chronic pain.

[Two cases of postpartum pubis diastasis mistaken for neurological complications of epidural analgesia]. / Dos casos de diástasis de pubis postparto interpretados como complicación neurológica de la analgesia epidural.

Two healthy 31- and 34-year-old parturients received uncomplicated epidural analgesia for labor and delivery using standard techniques. Twenty-four and 12 hours postpartum, respectively, they developed severe lower back pain and difficulty moving their lower extremities. At first the symptoms were attributed to neurological complications of epidural analgesia and for this reason the anesthetist was called. Although both women appeared healthy and the neurological examinations were normal, emergency computed tomography scans were performed to rule out spinal compression because of the severity of pain and difficulty of movement. The diagnosis was only established after suspecting pubis diastasis, confirmed by palpation of symphysis gaps of 3 and 2 cm, respectively. Pelvic dysfunction associated with pregnancy and labour is a complication whose incidence varies from 1 in 300 to 1 in 30,000. It presents with severe pain located in the areas supplied by pudendal and genitofemoral nerves. The pain may radiate to the sacroiliac joints and shoot down the buttocks and legs. In the most severe cases it may be accompanied by urinary dysfunction and inability to walk. If the clinical features are not recognized, it can be difficult to differentiate pubis diastasis from severe neurological complications in women who have received a central nervous system block. We report two cases of peripartum pubis symphysis diastasis that were both initially mistaken for neurological complications of epidural analgesia for labor.
