Review
Femoroacetabular impingement syndrome (FAIS) is an increasingly prevalent pathology in young and active patients, that has contributing factors from both abnormal hip morphology as well as abnormal hip motion. Disease progression can be detrimental to patient quality of life in the short term, from limitations on sport and activity, as well as the long term through early onset of hip arthritis. However, several concurrent or contributing pathologies may exist that exacerbate hip pain and are not addressed by arthroscopic intervention of cam and pincer morphologies. Lumbopelvic stiffness, for instance, places increased stress on the hip to achieve necessary flexion. Pathology at the pubic symphysis and sacroiliac joint may exist concurrently to FAIS through aberrant muscle forces. Additionally, both femoral and acetabular retro- or anteversion may contribute to impingement not associated with traditional cam/pincer lesions. Finally, microinstability of the hip from either osseous or capsuloligamentous pathology is increasingly being recognized as a source of hip pain. The present review investigates the pathophysiology and evaluation of alternate causes of hip pain in FAIS that must be evaluated to optimize patient outcomes.

BACKGROUND
Open surgical treatment of the pubic region and adductor related pathologies require an exact knowledge of the arterial blood supply of the symphysis pubis that seems furthermore important to explain the hematogenous occurrence of symphysitis. Pubic bone marrow oedema (PBME) is a frequent occurring magnetic resonance imaging finding in groin pain. However, even asymptomatic athletes present PBME and a correlation to the physical activity or higher blood flow was suggested. Data on the vascular anatomy of the symphysis pubis are rare.
METHODS
Ten formaldehyde-embalmed cadavers were dissected, and the arterial blood supply was investigated and photographically documented.
RESULTS
In the majority of cases the following pattern was determined: superior-inferior epigastric artery (n=12 hemipelves), inferior - dorsal artery of the penis/dorsal artery of the clitoris (n=16), posterior- obturator artery (n=16 hemipelves), anterior- deep external pudendal artery (n=14 hemipelves). Besides variations for the deep external pudendal artery anteriorly, we observed a highly variable arterial supply, especially superior. Superior in 4/10 cadavers, inferior in 0/10 cadavers, posterior in 2/10 cadavers and anterior in 5/10 cadavers side variations were found.
CONCLUSION
The symphysis pubis has a spatial and rich organized arterial blood supply with several variations. Despite the symphysis pubis is recognized as bradytroph, the high number of vessels is presumably required in stress situations for example in heavy training.

BACKGROUND AND OBJECTIVE
During vaginal delivery, several positions can be adopted by the mother to be more comfortable and to help the labor process. The positions chosen are very influenced by factors such as monitoring and intervention during the second stage of labor. However, there is limited evidence to support the most ideal birthing position. This work aims at contributing to a better knowledge associated with the widening of the pubic symphysis and the biomechanics of flexible and non-flexible sacrum positions that can be adopted during the second stage of labor, as well as their resulting pathophysiological consequences.
METHODS
A validated computational model composed by the pelvic floor muscles attached to the bones, and a fetus head was used to simulate vaginal deliveries. This model was modified to mimic two birthing positions: one that allows the free movement of the coccyx as in flexible sacrum positions and other in which this movement is more restricted as in non-flexible sacrum positions. The widening of the pubic symphysis was also considered to facilitate the passage of the fetus head.
RESULTS
The results obtained showed that, in non-flexible sacrum positions, where the coccyx movement is restricted, occur a rotation of 3.6° of the coccyx and a widening of 6 mm of the pubic symphysis. In contrast, in flexible sacrum positions, where the coccyx is free to move, occur a rotation of 15.7° of the coccyx and a widening of the pubic symphysis of 3 mm, appearing to be more beneficial for the mother's pelvis, but slightly higher stresses were detected in the pelvic floor muscles.
CONCLUSIONS
Globally, the results obtained allow to conclude that different birthing positions lead to changes in the female pelvic space, so certain positions can be adopted by the mother during the second stage of labor to reduce the risk of obstructed labor and the development of several dysfunctions. More specifically, flexible sacrum positions, such as kneeling, standing, squatting and sitting positions, are more beneficial for the bone structure of her pelvis as they allow a higher coccyx movement and lower widening of the pubic symphysis.

INTRODUCTION
Operative fixation of a disrupted symphysis pubis helps return alignment and stability to a traumatized pelvic ring. Implant loosening or failure has been demonstrated to commonly occur at some subacute point during the postoperative period. The purpose of this study is to report on a series of patients with traumatic pelvic ring disruptions to determine the incidence and common factors associated with early postoperative symphyseal plate failure before 7 weeks.
MATERIALS AND METHODS
126 patients retrospectively identified with unstable pelvic injuries treated with open reduction and plate fixation of the symphysis pubis and iliosacral screw fixation. Preoperative and postoperative radiographs, computed tomography (CT) images, and medical chart were reviewed to determine symphyseal displacement preoperatively and postoperatively, time until plate failure, patient symptoms and symphyseal displacement at failure, subsequent symphyseal displacement, incidence of additional surgery, and patient weight bearing compliance.
RESULTS
14 patients (11.1%) sustained premature postoperative fixation failure. 13 patients had anteroposterior compression (APC)-II injuries and 1 patient had an APC-III injury. Preoperative symphyseal displacement was 35.6 millimeters (mm) (20.8-52.9). Postoperative symphyseal space measurement was 6.3mm (4.7-9.3). Time until plate failure was 29days (5-47). Nine patients (64.2%) noted a pop surrounding the time of failure. Symphyseal space measurement at failure was 12.4mm (5.6-20.5). All patients demonstrated additional symphyseal displacement averaging 2.6mm (0.2-9.4). Two patients (14.2%) underwent revision. Four patients (28.5%) were non-compliant.
CONCLUSION
Premature failure of symphysis pubis plating is not uncommon. In this series, further symphyseal displacement after plate failure was not substantial. The presence of acute symphyseal plate failure alone may not be an absolute indication for revision surgery. Making patient education a priority could lead to decreased postoperative non-compliance and potentially a decreased incidence of implant failure. Posterior pelvic ring fixation aides overall pelvic ring stability and may help minimize further displacement after early postoperative symphyseal plate failure. Further functional outcome and biomechanical studies surrounding early symphyseal plate failure are needed.

CLINICAL/METHODICAL ISSUE
Osteitis pubis is one of the most common causes of chronic groin pain in many professional athletes. Symphysitis pubis with instability of the joint due to softening of the joint capsule and muscular imbalance of the corresponding muscles increases the instability of the sympyseal region, thus, resulting in a vicious cycle.
STANDARD RADIOLOGICAL METHODS
Magnetic resonance imaging (MRI).
METHODICAL INNOVATIONS
Optimized MRI sequence protocol with oblique (axial oblique) layers parallel to the linea arcuata of iliac bone together with large image field for depiction of the entire pelvis and high-resolution sequences focused on the symphysis pubis.
PERFORMANCE
Recently, the correlation between MRI signs of osteitis pubis and long-term clinical outcome in a group of professional soccer players was examined. In particular, edema in the peri-osseous tissue and isolated muscle lesions around the symphysis at the onset of symptoms were associated with partial recovery of the athletes. Furthermore, a significant association of increased normalized signal intensity in the pubic bone on STIR (short-tau inversion recovery) sequences (corresponding presence and signal intensity of bone marrow edema) and a poor complete clinical improvement was observed.
ACHIEVEMENTS
An optimized MRI protocol allows the diagnosis of osteitis pubis and provides important prognostic information.
PRACTICAL RECOMMENDATIONS
In case of clinical suspicion on osteitis pubis, MR imaging with an optimized sequence protocol should be performed.

Review
MR imaging evaluation can be valuable in patients with prior surgery for athletic pubalgia presenting with new, recurrent, or persistent groin pain. The clinical and interventional history as well as comparison with preoperative imaging is essential for imaging interpretation. Imagers should be aware of expected and unexpected postoperative findings. MR imaging findings concerning for infection, new injury, contralateral injury, or concomitant sources of symptoms (such as hip pathology) should be reported when present.

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.

BACKGROUND
The decreased hip range of motion seen in femoroacetabular impingement syndrome (FAIS) may lead to compensatory increased motion at the symphysis pubis (SP) with resultant increased stress on the joint, which can subsequently lead to osteitis pubis.
PURPOSE
To quantify the prevalence of SP abnormalities in patients with FAIS through the use of imaging modalities and to compare outcomes based on the presence of SP abnormalities.
STUDY DESIGN
Cohort study; Level of evidence, 3.
METHODS
Radiographs and magnetic resonance imaging (MRI) scans of 1009 consecutive patients who underwent primary hip arthroscopy for FAIS from January 2012 to January 2016 were identified. Exclusion criteria were patients undergoing revision or bilateral surgery, patients with dysplasia, and patients with less than 2-year follow-up. On radiographs, SP joints were reviewed for joint surface erosions, subchondral sclerosis and cysts, and ankylosis. MRI scans were reviewed for marrow edema in the subarticular pubic bone, subchondral sclerosis and cysts, joint surface erosions, and ankylosis. Patients with SP abnormalities were matched 1:2 to patients without SP abnormalities by age and body mass index. Outcomes included the Hip Outcome Score-Activities of Daily Living (HOS-ADL), HOS-Sports Subscale (HOS-SS), modified Harris Hip Score (mHHS), International Hip Outcome Tool-12 (iHOT-12), and visual analog scales (VAS) for pain and satisfaction.
RESULTS
830 patients were included; 23 (2.8%) demonstrated SP abnormalities. Of the 726 (72%) MRI scans reviewed, 15 (1.8%) showed bone marrow edema, subchondral sclerosis, erosions, or ankylosis. After matching, patients without SP abnormalities had significantly greater HOS-ADL (95.7 vs 83.0; P = .008), HOS-SS (91.6 vs 61.9; P = .003), iHOT-12 (89.5 vs 74.6; P = .046), and VAS satisfaction (91.3 vs 58.8; P = .004) scores, in addition to less postoperative pain (6.3 vs 23.5; P < .001). No significant differences were found in the mHHS (92.5 vs 82.2; P = .08). Patients without SP abnormalities had higher odds of achieving the minimal clinically important difference for the HOS-ADL (odds ratio [OR], 4.5; 95% CI, 1.3-14.1; P = .010), the HOS-SS (OR, 7.2; 95% CI, 1.8-18.5; P = .006), and the mHHS (OR, 14.5; 95% CI, 1.8-24.7; P = .013).
CONCLUSION
A low prevalence (1.8%-2.6%) of SP joint abnormality is seen on imaging in patients with FAIS. These patients may demonstrate significantly inferior clinical outcomes and persistent postoperative pain after FAIS treatment.

Percutaneous Fixation for Traumatic Symphysis Pubis Disruption-Are the Results Superior Compared to Open Techniques? A Systematic Review and Meta-Analysis of Clinical and Biomechanical Outcomes.
INTRODUCTION
Open reduction and reconstruction plate and screws fixation (RPSF) is considered the gold standard for the treatment of traumatic symphysis pubis diastasis (SPD). Percutaneous cannulated screw fixation (PCSF) has recently gained popularity as it may reduce operative time and morbidity. The current systematic review aims to compare the clinical and radiological outcomes of PCSF and RPSF in traumatic SPD and analyze the biomechanical effectiveness of PCSF.
MATERIAL AND METHODS
The Medline, Scopus, and Cochrane databases were searched until February 2023. The primary outcomes were the incidence of implant failure and revision surgery and the amount of displacement of symphysis pubis. Secondary outcomes were the intraoperative blood loss, the scar length, the operative time, the wound infection, and the patients' functional improvement.
RESULTS
Six clinical trial studies with a total of 184 patients and nine biomechanical studies were included. There was no significant difference between the two groups regarding the incidence of implant failure, the prevalence of revision surgery, and the amount of postoperative loss of reduction ( > 0.05 for all outcomes). The intraoperative blood loss (14.9 ± 4.2 mL for PCSF versus 162.7 ± 47.6 mL for PCSF, < 0.001) and the incision length (1.7 ± 0.9 mL for PCSF versus 8 ± 1.4 mL for PCSF, < 0.001) were significantly lower after PCSF. The mean operative time was 37 ± 19.1 min for PCSF and 68.9 ± 13.6 min for RPSF ( < 0.001). The infection rate was less frequent in the PCSF group (3% for PCSF versus 14.3% for RPSF, = 0.01). One clinical trial reported better functional recovery after PCSF. In all biomechanical studies, the threshold for implant failure was beyond the applied forces corresponding to daily activities.
CONCLUSIONS
PCSF for traumatic SPD is associated with less operative time, less blood loss, and a lower infection rate when compared to conventional plate techniques without increasing the incidence of postoperative fixation failure and revision surgery. Moreover, PCSF has been proven to be biomechanically sufficient for stabilization. Therefore, it should be considered an efficient and viable alternative for the reconstruction of SPD when closed reduction can be adequately achieved.
