Groin pain in soccer players: anatomy, clinical presentation, biomechanics, pathology and imaging findings

Groin pain is extremely common in soccer players, especially male soccer players, with nearly a third experiencing groin pain over the course of their careers. Despite its high prevalence, there continues to be some confusion and controversy regarding the detailed anatomy and recommended terminology related to groin pain in athletes. This article will review the anatomy, clinical presentation, biomechanics, pathology and imaging findings most commonly associated with groin pain in soccer players.

Dynamic Magnetic Resonance Imaging (MRI) in Inguinal-Related Chronic Groin Pain (CGP): Comparison With Systematic Surgical Assessment

Objective This study aimed to assess the performance of dynamic MRI in Chronic Groin Pain (CGP) related to the inguinal region, comparing it with surgery as the gold standard. Materials and methods A cohort of 25 consecutive patients exhibiting persistent clinical inguinal-related CGP underwent a pre-surgical pelvis MRI. Imaging encompassed strictly axial Fast Spin Echo (FSE) T1 sequences, both without (static sequence) and with Valsalva Maneuver (VM, dynamic sequence), alongside axial-oblique Proton Density weighted with Fat Saturation (PDFS). Evaluation of these sequences focused on identifying Abdominal Wall (AW) injuries. A consistent surgical approach was employed by the same surgeon across all patients (34 AW injuries in 25 patients). Specificity (Sp), Sensitivity (Se), Negative Predictive Value (NPV), Positive Predictive Value (PPV), and overall accuracy of MRI sequences and their combinations for detecting AW injuries were computed by comparing them to surgical findings. Results Ninety sequences were obtained, revealing that the axial PDFS oblique sequence emerged as the most singularly reliable (Accuracy: 58.82%). The optimal sequence combination was found to be axial T1 combined with axial T1 VM, exhibiting an accuracy of 75.00% (Se: 85.71%, Sp: 70.59%, PPV: 54.55%, NPV: 92.31%, with an average duration of 4 minutes and 31 seconds). Conclusion Based on our findings, we advocate for the adoption of the axial FSE T1 combined with Valsalva Maneuver as a dependable protocol for inguinal-related CGP, characterized by a highly reasonable examination duration.

The EFSUMB Guidelines and Recommendations for Musculoskeletal Ultrasound - Part I: Extraarticular Pathologies

The first part of the guidelines and recommendations for musculoskeletal ultrasound, produced under the auspices of the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB), provides information about the use of musculoskeletal ultrasound for assessing extraarticular structures (muscles, tendons, entheses, ligaments, bones, bursae, fasciae, nerves, skin, subcutaneous tissues, and nails) and their pathologies. Clinical applications, practical points, limitations, and artifacts are described and discussed for every structure. After an extensive literature review, the recommendations have been developed according to the Oxford Centre for Evidence-based Medicine and GRADE criteria and the consensus level was established through a Delphi process. The document is intended to guide clinical users in their daily practice.

Surgical Outcomes of Inguinal-, Pubic-, and Adductor-Related Chronic Pain in Athletes: A Systematic Review Based on Surgical Technique

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.

Totally extra-peritoneal repair versus trans-abdominal pre-peritoneal repair for the laparoscopic surgical management of sportsman's hernia: A systematic review and meta-analysis

BACKGROUND

Open and laparoscopic modalities are employed for treatment of sportsman's hernia with totally extra-peritoneal (TEP) and trans-abdominal pre-peritoneal (TAPP) laparoscopic approaches both currently being utilised. At present, neither subtype has demonstrated a beneficial superiority for sportsman's hernia repair, as concluded in the most recent systematic review comparing the outcomes of each technique. The aim of this review was to evaluate current evidence to ascertain whether there was a difference in laparoscopic techniques following sportsman's hernia repair.

METHODS

A systematic literature search was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement standards. Databases searched included PubMed, Scopus and Web of Science to identify all randomised controlled trials (RCTs) and observational studies Risk of bias was assessed using the Cochrane risk of bias tool and Newcastle-Ottawa scale for RCTs and observational studies, respectively.The assessed outcomes included median time to return to sporting activity, complications and the degree of postoperative pain reduction within three months. Random effects model was used to calculate pooled proportion data where feasible. Subgroup analyses were also performed.

RESULTS

28 studies were identified including 2 RCTs and 26 observational studies. No significant differences were observed between techniques in the primary or secondary outcomes. Significant heterogeneity was observed in all outcomes. This was more pronounced for return to sporting activity meaning that meta-analysis was not feasible in this domain. Median time to return to sporting activity was 28 days for both techniques.

CONCLUSIONS

There is no observed difference in the primary and secondary outcomes in either technique. An RCT comparing TEP and TAPP repair is needed to provide definitive data on this matter.

Outcomes following surgical management of inguinal-related groin pain in athletes: a case series

To determine the outcomes of a limited surgical intervention, consisting of neurolysis, inguinal wall repair and/or adductor debridement of adhesions based on intraoperative findings. Retrospective case series. Outpatient orthopedic/general surgery clinic. Fifty-one athletes treated surgically for inguinal-related groin pain from 2009 to 2015. Limited surgical intervention, consisting of neurolysis, inguinal wall repair and/or adductor debridement based on intra-operative findings. Ability to return to sport at the same level, time to return to play. Fifty-one athletes were included in the study with an average follow-up of 4.42 years (range 2.02–7.01). The average age was 24.2 years (range 16–49) and consisted of 94.0% males and 6.0% females. Nerve entrapment was demonstrated in 96.2% of cases with involvement of the ilioinguinal in 92.5%, the iliohypogastric in 30.8% and the genitofemoral in 13.2%. Attenuation of the posterior inguinal wall was present and repaired in 79.3% of cases. Scar tissue was present around the adductor origin and required debridement in 56.7% of cases. Forty-nine (96.1%) athletes returned to sport at the same level of play at an average of 5.9 weeks. Two athletes required a revision surgery. High rates of return to sport were achieved after surgery for inguinal-related groin pain that addresses the varying pathology and associated nerve entrapment.

Surgical or conservative treatment in ARGP syndrome? A systematic review

Background and aim of the work: The rectus-adductor syndrome is a common cause of groin pain. In literature the adductor longus is reported as the most frequent site of injury so that the syndrome can be fitted into the adductor related groin pain (ARGP) group. The aim of this study was to define what is the best treatment between surgical and conservative in athletes affected by ARGP in terms of healing and return to play (RTP) time. Methods: A systematic review was performed searching for articles describing studies on RTP time for surgical or conservative interventions for ARGP. A qualitative synthesis was performed. Only 10 out 7607 articles were included in this systematic review. An exploratory meta-analysis was carried out. Due to high heterogeneity of the included studies, raw means of surgery and conservative treatment groups were pooled separately. A random effects model was used. Results: The results showed quicker RTP time for surgery when pooled raw means were compared to conservative treatments: 11,23 weeks (CI 95%, 8.18,14.28, p<0.0001, I^2=99%) vs 14,9 weeks (CI 95%, 13.05,16.76, p<0.0001, I^2 = 77%). The pooled results showed high statistical heterogeneity (I^2), especially in the surgical group. Conclusions: Surgical interventions are associated with quicker RTP time in athletes affected by ARGP, but due to the high heterogeneity of the available studies and the lack of dedicated RCTs this topic needs to be investigated with dedicated high quality RCT studies.

Imaging of inguinal-related groin pain in athletes

Inguinal canal-related groin pain is common in athletes and may involve numerous structures such as the conjoint tendon and the transversalis fascia. Ultrasound is the only dynamic tool that shows the passage of preperitoneal fat at the level of the Hesselbach triangle and allows excluding true inguinal hernias. Fascia transversalis bulging and inguinal ring dilatation may also be described. MRI assesses injuries of rectus abdominis and adductor longus enthesis and osteitis symphysis but its accuracy for the diagnosis of inguinal-related groin pain remains debated.

MRI in chronic groin pain: sequence diagnostic reliability compared to systematic surgical assessment

OBJECTIVE

To determine the diagnostic reliability of magnetic resonance imaging (MRI) sequences in chronic groin pain (CGP) compared to surgery and try to propose a suitable MRI protocol.

MATERIALS AND METHODS

Forty-three consecutive patients with resistant clinical CGP underwent a pre-surgical pelvis MRI. Eight MRI sequences were acquired: axial fast spin-echo T1-weighted (FSE T1), coronal FSE T1, axial-oblique (in symphysis plane) proton density weighted with fat saturation (PDFS), coronal PDFS, sagittal PDFS, axial FSE T1 with fat saturation and gadolinium enhancement (FSGE), coronal FSE T1 FSGE and axial FSE T1 with Valsalva maneuver (VM). These sequences were reviewed for pubic symphysis assessment, adductor longus (AL) tendon and abdominal wall (AW) injuries. The same surgeon operated on all of these patients (26 AL and 49 AW). Sensitivity (Se), specificity (Sp), positive predictive value (PPV), negative prospective value (NPV) and accuracy of each sequence and combinations for AL or AW injuries were calculated in comparison to surgical findings.

RESULTS

One hundred ninety-two sequences were obtained. Coronal T1 FSGE and axial T1 VM proved to be the most reliable sequences (accuracy: 91.67% in AL and 83.33% in AW). The best sequence combination was coronal T1, axial PDFS, sagittal PDFS and axial T1 VM (accuracy: 77.78%; Se: 100.00%, Sp: 69.23%, PPV: 55.56%, NPV: 100.00%).

CONCLUSION

MRI has 77.78% accuracy, 100.00% sensitivity, 69.23% specificity, 55.56% PPV and 100.00% NPV in evaluating CGP, with coronal T1-axial PDFS-sagittal PDFS-axial T1 VM as the optimal protocol in terms of diagnostic performance within a reasonable scan time. Diagnostic performance of MRI was examined in the evaluation of CGP using surgery as reference standard.

[Chronic instability of the pubic symphysis : Etiology, diagnostics and treatment management]

The most frequent causes of chronic instability of the pubic symphysis are sports-related continual overload and traumatic symphyseal injuries. Acute injury of the pubic symphysis may be the result of external forces acting on the anterior pelvic ring or the result of internal forces, such as those arising during parturition. The postpartum form of instability following a complication-free birth is reversible and usually returns to normal within a few months through strengthening of the pelvic floor muscles. Residual instability of the pubis symphysis is on the whole a rare complication. Although established therapy options for acute symphyseal separation can be found in the literature, there are only a few case reports on chronic symphyseal instability. There are no guidelines on standardized therapy options. This review article examines the etiology, clinical findings, diagnostic techniques and management options for patients suffering from chronic symphyseal instability.
