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.

Review
The interpubic cavity (cleft) is a narrow, slit-like, oval-shaped cavity which has frequently been described within the fibrocartilaginous interpubic disc. The aim of this article is to thoroughly analyze what is known about the interpubic cavity. The following three scientific databases (PubMed, Web of Science and Google Scholar) were systematically searched. Combinations of the search terms "interpubic cleft", "interpubic cavity", "symphysis pubis cleft", "symphysis pubis cavity" and "symphysis cleft sign" were used. All databases were searched from inception until August of 2022. Searching of the three databases resulted in 711 hits, of which 280 remained after checking for duplicates. In the first step, 152 studies were excluded due to irrelevant content. Thus, 128 proceeded to the second step, of which 23 were finally selected for meeting the objectives of this review. Until now the reason for the cavity forming remains unclear. The interpubic cavity is present in the anterior portion of the interpubic disc, within 2 mm from its anterior margin. There is no predilection in the craniocaudal dimension. The secondary cavity is usually called a "cleft sign". The results of our scoping review summarize information about the interpubic cavity. Its composition and morphology are still not well understood.

Avulsion fractures of the pelvis and hip region are typical injuries in adolescent athletes. Avulsion sites include the muscle tendon origin or insertion, and treating these injuries surgically or conservatively remains a debated issue. The main goals of this review were to assess and summarize injury types and sites, treatment-related clinical outcomes, and return to sport for adolescent patients with a pelvis avulsion fracture and to provide support for making treatment decisions. The PubMed database was searched in November 2021 to identify all published articles from 2000 to 2021 that reported the outcome and return to sport after conservative or surgical treatment. Eighteen studies with 453 patients were included in this review. The age range was 13.6-16.8 years. The most common injury site the was anterior superior iliac spine (37%), followed by the anterior inferior iliac spine (31%), ischial tuberosity (14%), lesser trochanter (9%), iliac crest (8%), and superior corner of the pubic symphysis (1%). Overall complications were lower in the surgical group compared to the conservative group. The rate of return to pre-injury activity level was greater in patients who underwent surgical treatment ( < 0.05). In conclusion, surgery is preferred for major dislocation and fragment size, providing a better return-to-sport rate and decreasing the risk of complications.

Meta-Analysis
In low- and middle-income countries (LMIC), measurement of symphysis fundal height (SFH) is often the only available method of estimating gestational age (GA) in pregnancy. This systematic review aims to summarize methods of SFH measurement and assess the accuracy of SFH for the purpose of GA estimation. We searched PubMed, EMBASE, Cochrane, Web of Science, POPLINE, and WHO Global Health Libraries from January 1980 through November 2021. For SFH accuracy, we pooled the variance of the mean difference between GA confirmed by ultrasound versus SFH. Of 1,003 studies identified, 37 studies were included. Nineteen different SFH measurement techniques and 13 SFH-to-GA conversion methods were identified. In pooled analysis of five studies (n = 5838 pregnancies), 71% (95% CI: 66-77%) of pregnancies dated by SFH were within ±14 days of ultrasound confirmed dating. Using the 1 cm SFH = 1wk assumption, SFH underestimated GA compared with ultrasound-confirmed GA (mean bias: -14.0 days) with poor accuracy (95% limits of agreement [LOA]: ±42.8 days; n = 3 studies, 2447 pregnancies). Statistical modeling of three serial SFH measurements performed better, but accuracy was still poor (95% LOA ±33 days; n = 4 studies, 4391 pregnancies). In conclusion, there is wide variation in SFH measurement and SFH-to-GA conversion techniques. SFH is inaccurate for estimating GA and should not be used for GA dating. Increasing access to quality ultrasonography early in pregnancy should be prioritized to improve gestational age assessment in LMIC.

Meta-Analysis
OBJECTIVE
Collection and meta-analysis of all relevant anatomical studies related to the pubic symphysis to provide a state of the art review of its musculotendinous and ligamentous attachments from 2010 to date.
METHODS
A systematic search of published literature databases (PubMed, Web of Science and Embase) was conducted according to the PRISMA guidelines from January 2010 up until now. All papers investigating the anatomy of the musculotendinous attachments of the pubis and the pubic ligaments were eligible. Methodological quality was assessed using the Quality Appraisal for Cadaveric Studies (QUACS scale). A narrative analysis approach was adopted to synthesize the findings.
RESULTS
After screening and review of 1313 papers, a total of six studies investigating the anatomy of the pubic ligaments and tendons were included. Of the six articles included in this systematic review, five articles performed a macroscopic anatomical dissection, three articles performed a microscopic (histological) study, and one article combined microscopic examination with an MRI imaging examination. The anatomy of the pubic symphysis was examined in 76 anatomical cadavers (60 embalmed, 16 fresh frozen). In total 44 male cadavers (58%), 28 female cadavers (37%) and four cadavers whose gender was not stated were dissected.
CONCLUSION
The age-old accepted concept of the fusion of the rectus abdominis with the adductor longus via the aponeurotic plate is outdated. New anatomical concepts like the pyramidalis-anterior pubic ligament-adductor longus complex (PLAC), recto-gracilis tendon, fusion of adductor brevis with gracilis, etc. are recently introduced. The awareness of anatomy and morphology of the pubic ligaments plays a significant role in understanding the diagnosis and treatment of groin pain.

Review
INTRODUCTION
Cleidocranial dysplasia (CCD) is a rare disease characterized by craniofacial, skeletal, and oral anomalies. The disease prevalence is estimated to be 1 per million inhabitants; thus, only a few studies have described large cohorts of CCD patients. This study reviewed the clinical-radiological and demographic characteristics of patients with CCD in South America.
METHODS
We conducted a systematic review of all cases of CCD reported in South America following the PRISMA guidelines. Demographic information (sex, age at diagnosis, origin, reason for consultation, and family history) was also recorded. CCD signs were divided into "craniofacial" and "skeletal" categories.
RESULTS
A total of 72 cases were included. We found that oral anomalies were the most common reason for consultation leading to a diagnosis in patients, with a median age at diagnosis of 14 years. Fifty percent of the patients were women. Open fontanels or cranial sutures, the presence of at least one of the typical CCD facies (frontal bossing, brachycephaly, hypertelorism, or depression of the nasal bridge), and supernumerary teeth were reported in 92%, 85%, and 88% of cases, respectively. Clavicular dysplasia was present in 98.6% of cases, and other skeletal abnormalities such as scoliosis, pubic symphysis diastasis, and flat feet were found; short stature was present in 71% of cases, and one case presented cognitive deficits.
CONCLUSION
Although the phenotypic spectrum of CCD is variable, clavicular dysplasia, open fontanels or cranial sutures, dental anomalies, and at least one of the typical CCD facies are present in at least 80% of cases.

Meta-Analysis
Age estimation is one of the essential criteria in the identification process. The method of age estimation employed depends on the availability of skeletal material brought for forensic examination. McKern and Stewart's method constitutes one of the principal approaches towards pubic symphyseal age estimation. The method entails evaluating morphological changes within the pubic symphysis and subsequently allotting a specific score corresponding to the observed changes. Based on the obtained scores, an age range is then assigned to the remains presenting for examination. The present systematic review was undertaken to ascertain the applicability of the McKern-Stewart method for age estimation. Studies pertaining to the use of the McKern-Stewart method for age estimation in skeletal remains were retrieved by keying in a combination of MeSH terms and other free terms from four databases. The retrieved articles were subjected to a stringent inclusion and exclusion criteria, following which the risk of bias was assessed and the overall quality of evidence was established. Once the final tally of relevant articles was obtained, data specific to the mean age corresponding to each score was extracted. Non-parametric tests and boxplots were employed to compare the mean ages reported across multiple studies. The present systematic review concludes that the McKern-Stewart method can be applied for the purpose of age estimation in skeletal remains. Broader age cohorts for higher scores, as well as, overlapping values for age ranges in relation to the cumulative scores, however, can be considered a limitation for its applicability in forensic case work.

Meta-Analysis
Suchey-Brooks method has been studied many times with varying reports of accuracy and reliability. A systematic review and meta-analyses were utilized to quantitatively determine the accuracy and reliability of the Suchey-Brooks (S-B) method. A systematic search of PubMed and EBSCO health and medical databases was performed. Meta-analyses were performed to quantify the relationship between actual known age at death and the S-B method using Spearman's Rho and Pearson's r for (1) combined males and females estimates, (2) male-only estimates, and (3) female-only estimates. Overall correlation coefficient using Cohen's kappa, Spearman's Rho, and Pearson's r was also calculated to determine the interrater and intrarater reliability using the S-B method. Eighteen studies classified as moderate-to-high methodological quality met the inclusion criteria. The sample sizes were different for the combined male and female (n = 2620), male-only (n = 2602), and female-only (n = 1431) meta-analyses. The effect size of the age at death meta-analyses was large and significant for combined males and females (Spearman's Rho = 0.62; Pearson's r = 0.65), male-only (Spearman's Rho = 0.77; Pearson's r = 0.75), and female-only (Spearman's Rho = 0.71; Pearson's r = 0.71). The overall correlation coefficients of the interrater (Kappa = 0.76; Spearman's Rho = 0.73; Pearson's r = 0.80) and intrarater (Kappa = 0.81; Spearman's Rho = 0.91; Pearson's r = 0.83) reliability meta-analyses were large and significant. A significant degree of heterogeneity was present in all meta-analyses, with minimal evidence of publication bias. The meta-analyses results suggest the S-B method is highly reliable with a moderate-to-high degree of accuracy. Our results also identified sample size and accuracy differences between male and female individuals.

Orthopaedic Journal of Sports Medicine Sep 2021Controversies remain regarding the surgical treatment of inguinal-, pubic-, and adductor-related chronic groin pain (CGP) in athletes. (Review)
Review
BACKGROUND
Controversies remain regarding the surgical treatment of inguinal-, pubic-, and adductor-related chronic groin pain (CGP) in athletes.
PURPOSE
To investigate the outcomes of surgery for CGP in athletes based on surgical technique and anatomic area addressed.
STUDY DESIGN
Systematic review; Level of evidence, 4.
METHODS
The PubMed and Embase databases were searched for articles reporting surgical treatment of inguinal-, pubic-, or adductor-related CGP in athletes. Inclusion criteria were level 1 to 4 evidence, mean patient age >15 years, and results presented as return-to-sport, pain, or functional outcomes. Quality assessment was performed with the CONSORT (Consolidated Standards of Reporting Trials) statement or MINORS (Methodological Index for Non-randomized Studies) criteria. Techniques were grouped as inguinal, adductor origin, pubic symphysis, combined inguinal and adductor, combined pubic symphysis and adductor, or mixed.
RESULTS
Overall, 47 studies published between 1991 and 2020 were included. There were 2737 patients (94% male) with a mean age at surgery of 27.8 years (range, 12-65 years). The mean duration of symptoms was 13.1 months (range, 0.3-144 months). The most frequent sport involved was soccer (71%), followed by rugby (7%), Australian football (5%), and ice hockey (4%). Of the 47 articles reviewed, 44 were classified as level 4 evidence, 1 study was classified as level 3, and 2 randomized controlled trials were classified as level 1b. The quality of the observational studies improved modestly with time, with a mean MINORS score of 6 for articles published between 1991 and 2000, 6.53 for articles published from 2001 to 2010, and 6.9 for articles published from 2011 to 2020. Return to play at preinjury or higher level was observed in 92% (95% CI, 88%-95%) of the athletes after surgery to the inguinal area, 75% (95% CI, 57%-89%) after surgery to the adductor origin, 84% (95% CI, 47%-100%) after surgery to the pubic symphysis, and 89% (95% CI, 70%-99%) after combined surgery in the inguinal and adductor origin.
CONCLUSION
Return to play at preinjury or higher level was more likely after surgery for inguinal-related CGP (92%) versus adductor-related CGP (75%). However, the majority of studies reviewed were methodologically of low quality owing to the lack of comparison groups.
