Association between hip muscle strength/function and hip cartilage defects in sub-elite football players with hip/groin pain.

OBJECTIVE: To explore associations between hip muscle strength and cartilage defects (presence and severity) on magnetic resonance imaging (MRI) in young adults with hip/groin pain participating in sub-elite football. DESIGN: Sub-elite football players with hip/groin pain (>6 months) completed assessments of isometric hip strength and functional task performance. Hip cartilage defects were assessed using the Scoring Hip Osteoarthritis with MRI tool. This exploratory, cross-sectional study used logistic and negative binomial models to assess the relationships between hip muscle strength or functional task performance and hip cartilage defects, controlling for body mass index, age, testing site and cam morphology, incorporating sex-specific interaction terms. RESULTS: One hundred and eighty-two (37 women) sub-elite (soccer or Australian football) players with hip/groin pain (age 26 ± 7 years) were included. Greater hip extension strength was associated with higher cartilage total score (adjusted incidence rate ratio [aIRR] 1.01, 95%CI: 1.0 to 1.02, p = 0.013) and superolateral cartilage score (adjusted odds ratio (aOR) 1.03, 95% confidence interval (CI): 1.01 to 1.06, p < 0.01). In female sub-elite football players, greater hip external rotation strength was associated with lateral cartilage defects (aOR 1.61, 95%CI: 1.05 to 2.48, p = 0.03) and higher cartilage total score (aIRR 1.25, 95%CI: 1.01 to 1.66, p = 0.042). A one-repetition increase in one-leg rise performance was related to lower odds of superomedial cartilage defects (aOR 0.96, 95%CI: 0.94 to 0.99, p < 0.01). CONCLUSIONS: Overall, there were few associations between peak isometric hip muscle strength and overall hip cartilage defects. It is possible that other factors may have relevance in sub-elite football players. Additional studies are needed to support or refute our findings that higher one leg rise performance was associated with reduced superomedial cartilage defect severity and greater hip extension strength was related to higher cartilage defect severity scores.

Management of inguinal lymph nodes in locally advanced, surgically unresectable, squamous cell carcinoma of the vulva.

OBJECTIVE: To assess clinical outcomes of inguinal lymph node surgical resection compared to primary groin radiotherapy for locally advanced, surgically unresectable vulvar cancer. METHODS: All patients treated with radiation for vulvar cancer were identified between Jan 1, 2000 - Dec 31, 2020 at 2 academic centres. Inclusion criteria were those treated with curative intent primary radiotherapy +/- chemotherapy, tumors >4 cm, and surgically unresectable squamous cell vulvar carcinoma. Groin recurrence-free survival (RFS) was compared for groin surgery and primary groin radiotherapy using the Kaplan Meier method and log rank test. Groin failures are described by treatment modality, radiation dose and lymph node size. RESULTS: Of 476 patients treated with radiation for vulvar cancer, 112 patients (23.5%) met inclusion and exclusion criteria. The median (95% CI) follow up was 1.9 (1.4-2.5) years. Complete clinical response was significantly higher (80.0%) in patients with surgical groin resection compared to patients treated with primary groin radiotherapy (58.2%) (p = 0.04). On multivariable analysis, after adjusting for clinical and/or radiologically abnormal lymph nodes (p = 0.67), surgical groin resection was significantly associated with lower groin recurrence (HR 0.2 (95%CI 0.05-0.92), p = 0.04). The 3-year groin recurrence-free survival (RFS) was significantly higher at 94.4% (87.1-100) in patients with surgical groin resection compared to 79.2% (69.1-90.9) in patients treated with primary radiation (p = 0.02). CONCLUSIONS: In locally advanced squamous cell vulvar cancer, surgical groin management improves groin RFS compared to radiotherapy alone.

Staged urethroplasty with groin full-thickness skin graft for managing complex anterior urethral strictures: surgical outcomes and predictive factors.

PURPOSE: To describe outcomes of staged-urethroplasty in complex anterior urethral strictures using full-thickness-skin-graft (FTSG) harvested from the hairless groin area, and to identify factors influencing successful outcomes. METHODS: Through retrospective chart review, we identified a total of 67 men who underwent the first-stage operation (grafting) using groin-FTSG for staged-urethroplasty to treat complex anterior urethral strictures unsuitable for one-stage urethroplasty. Among these, 59 underwent the second-stage operation (tubularization) at a median duration of 5.1-months after grafting. Patients were assessed for outcomes as scheduled after tubularization outcomes were analyzed only for 48 patients for whom ≥ 1-year follow-up data after tubularization were available. Their mean follow-up duration was 27.1 months. Success was defined as achieving physiologic voiding without requiring further procedures. RESULTS: Median stricture-length was 5.5 cm in all 67 patients. After grafting, neourethral-opening-narrowing occurred in 18. Partial graft-loss occurred in 8, of whom only 3 underwent re-grafting. The percentage of patients who achieved successful outcomes was 81.3%. Improvements in maximum-urine-flow-rate and post-void-residual-urine-volume were maintained until the last follow-up visit. A urethrocutaneous-fistula occurred in one patient, while meatal-stenosis occurred in two. On multivariate-regression-analysis, the presence of neourethral-opening-narrowing was the only predictor of non-success after tubularization. Furthermore, the presence of hypertension, longer stricture-length, and a history of prior direct-vision-internal-urethrotomy were predictors of the occurrence of neourethral-opening-narrowing. CONCLUSION: Staged-urethroplasty using groin-FTSG is well worth considering as a useful therapeutic option for complex anterior urethral strictures, with an acceptable success rate and low morbidity. The absence of neourethral-opening-narrowing after the first-stage operation leads to success.

Incisional Negative Pressure Wound Therapy After Revascularisation Surgery in Patients with Peripheral Arterial Disease: A Randomised Trial (PICO-Vasc Study).

OBJECTIVE: This study assessed the potential benefits of using incisional negative pressure wound therapy (iNPWT) for patients undergoing revascularisation due to peripheral arterial disease. METHODS: A prospective randomised controlled trial was conducted to compare the inguinal application of iNPWT vs. standard surgical dressings. Patients were enrolled from February 2021 to November 2022. A total of 133 groin incisions were randomised (66 intervention group, 67 control group). The randomisation sequence was carried out by permuted blocks and allocation assigned by opening opaque envelopes once the revascularisation procedure had finished. Wound healing and complication rates were assessed at post-operative days 5, 14, and 30. Primary and secondary endpoints were: 30 day post-operative surgical site infection (SSI) and surgical site occurrence (SSO) rates, defined as a surgical wound complication other than a SSI. Post-operative SSI was defined according to the US Centers for Disease Control and Prevention criteria. SSO included: wound dehiscence, seroma or lymphocele, haematoma, and lymphorrhagia. The study was registered at ClinicalTrials.gov database (NCT04840576) and reported according to the CONSORT guidelines. RESULTS: iNPWT did not modify the 30 day inguinal SSI and SSO rates (16.7% vs. 20.9% and 37.9% vs. 44.8%; p = .53, relative risk [RR] 0.999, 95% confidence interval [CI] 0.52 - 1.88 and p = .42, RR 1.29, 95% CI 0.89 - 1.86, respectively). It reduced the early SSO rate (19.7% vs. 35.8%; p = .044, RR 1.45, 95% CI 1.047 - 2.013) and post-operative seroma rate (4.6% vs. 19.4%; p = .014, RR 1.73, 95% CI 1.296 - 2.397). CONCLUSION: There were no differences in SSI and SSO rates, although statistically significant reductions in early SSO rates and seroma were found in the intervention group.

A morphological mimic: An NTRK3-rearranged spindle cell neoplasm presenting as a groin mass.

Neurotrophic receptor tyrosine kinase (NTRK)-rearranged spindle cell neoplasms are a recently described group of soft tissue tumors. They commonly present as a painless mass on the extremities of children and young adults. They are characterized microscopically by a heterogeneous spectrum of infiltrative spindle cell proliferations, which can morphologically mimic several other spindle cell neoplasms. Their identification is vital, as they may be amenable to treatment with tyrosine kinase-targeted therapy. This case report describes a rare NTRK3-rearranged spindle cell neoplasm in the groin of a 29-year-old female and provides further clinical and morphological features of this entity.

The association of permanent versus absorbable fixation on developing chronic post-herniorrhaphy groin pain in patients undergoing laparoscopic inguinal hernia repair.

INTRODUCTION: Fixation of mesh during minimally invasive inguinal hernia repair is thought to contribute to chronic post-herniorrhaphy groin pain (CGP). In contrast to permanent tacks, absorbable tacks are hypothesized to minimize the likelihood of CGP. This study aimed to compare the rates of CGP after laparoscopic inguinal hernia repair between absorbable versus permanent fixation at maximum follow-up. METHODS: This is a post hoc analysis of a randomized controlled trial in patients undergoing laparoscopic inguinal hernia repair (NCT03835351). All patients were contacted at maximum follow-up after surgery to administer EuraHS quality of life (QoL) surveys. The pain and restriction of activity subdomains of the survey were utilized. The primary outcome was rate of CGP, as defined by a EuraHS QoL pain domain score ≥ 4 measured at ≥ 1 year postoperatively. The secondary outcomes were pain and restriction of activity domain scores and hernia recurrence at maximum follow-up. RESULTS: A total of 338 patients were contacted at a mean follow-up of 28 ± 11 months. 181 patients received permanent tacks and 157 patients received absorbable tacks during their repair. At maximum follow-up, the rates of CGP (27 [15%] vs 28 [18%], P = 0.47), average pain scores (1.78 ± 4.38 vs 2.32 ± 5.40, P = 0.22), restriction of activity scores (1.39 ± 4.32 vs 2.48 ± 7.45, P = 0.18), and the number of patients who reported an inguinal bulge (18 [9.9%] vs 15 [9.5%], P = 0.9) were similar between patients with permanent versus absorbable tacks. On multivariable analysis, there was no significant difference in the odds of CGP between the two groups (OR 1.23, 95% CI [0.60, 2.50]). CONCLUSION: Mesh fixation with permanent tacks does not appear to increase the risk of CGP after laparoscopic inguinal hernia repair when compared to fixation with absorbable tacks. Prospective trials are needed to further evaluate this relationship.

Prophylactic Transversely Hemisected Sartorius Flap for High-Risk Groin Dissections in Vascular Surgery-A Case Series.

Groin wound dehiscence and infection are a common complication of femoral artery exposure. In patients with prosthetic conduits placed in the groin, these complications can lead to graft infection or anastomotic dehiscence with hemorrhage. Sartorius flaps can be useful in preventing graft infections or anastomotic breakdown in the setting of wound infections. Prophylactic sartorius flaps have been suggested to be a useful adjunct in patients who are at high risk for groin complications. Standard sartorius flaps can be difficult to perform and increase the operative time. We present our experience with a modified sartorius flap, a Transversely Hemisected Sartorius (THT), which avoids dissection to the anterior superior iliac spine. Patients who received femoral artery exposure and a modified prophylactic sartorius flap were included in this case series. The Penn Groin Assessment Scale (PGAS) was calculated for each patient and our primary outcome was the rate of deep space wound infections. Fifteen patients received a THT muscle flap. The average age of the cohort was 67.5 (35-86) years. Eight (50%) were male. The mean PGAS was 2.5 (0-6). Eight (50%) groins had a prosthetic conduit underlying the flap. Four (25%) patients had infrainguinal bypass, 3 (18.8%) for femoral-femoral bypass, and 1 (6.3%) patient received aortic-bifemoral bypass. Eight (50%) patients received sartorius flap after femoral artery exposure for thromboembolectomy, endarterectomy, or access complications. Six (37.5%) patients developed superficial surgical site infections however no deep space infections or prosthetic graft excisions resulted. This procedure was effective in preventing graft infections in all patients with high-risk features for groin infection in our retrospective case series. The segmental blood supply is maintained while providing good coverage of the femoral vessels with this rotational flap.

Management of groin hernias in emergency setting: differences in indications and outcomes between laparoscopic and open approach. A single-center retrospective experience.

PURPOSE: The use of minimally invasive groin hernia repair techniques in an emergency setting is still debated and its widespread is limited. The aim of this study is to evaluate the safety and efficacy of the laparoscopic transabdominal preperitoneal (TAPP) technique in the treatment of inguinal and femoral hernias in emergency setting based on our experience, comparing indications and outcomes with the open technique. METHODS: A retrospective analysis was performed including all patients with incarcerated and/or strangulated groin hernia who underwent emergency surgery from November 2019 to September 2022. Perioperative variables and short- and long-term outcomes were examined. Statistical analysis was performed using chi-square test for nominal variables and Student's t test for continuous ones. A p value < 0.05 was considered statistically significant. RESULTS: Sixty-six patients were included: 29 patients were treated with TAPP technique (Tapp group) and 37 with open technique plus diagnostic laparoscopy (Open group). Patients in the TAPP group were younger, had less severe clinical scenarios, and had a trend for lower Charlson Comorbidity Index, whereas ASA score and BMI were similar. The small bowel was more frequently herniated in the open group. Bilateral hernia repair was performed in 20.69% of patients in the Tapp group versus 0% in the Open group (p = 0.004). Bowel resection was more frequent in the open group (48.65% vs 0% of the Tapp group, p < 0.001) length of surgery was comparable in the two groups. In the Tapp group, the length of hospitalization was significantly shorter (2.59 ± 2.28 days vs. 9.08 ± 14.48 days; p = 0.023). Postoperative complications, according to Clavien-Dindo, were more severe in Open group where there were two deaths. There were no differences in the number of readmission and re-operations at 30 days and in the recurrence rate. CONCLUSIONS: Emergency repair of inguinal and femoral hernias using TAPP is a valuable option, safe and feasible in selected patients. In this series, indications for TAPP were reserved to younger patients with less comorbidities and less severe clinical scenario. Future randomized studies are needed to compare TAPP with open emergency hernia surgery in all settings. Potential advantages of TAPP are the reduction of postoperative complications, earlier recovery, and the possibility of bilateral treatment.

Groin injuries in women's premier league football in Norway: A two-season prospective cohort study describing clinical and imaging characteristics.

OBJECTIVE: To describe the prevalence, incidence, and burden of groin injuries in the Norwegian women's premier football league and to describe their clinical and imaging characteristics. METHODS: During the 2020 and 2021 seasons, players in the Norwegian women's premier league reported groin injuries weekly, using the Oslo Sports Trauma Research Centre Questionnaire on Health Problems (OSTRC-H2). We calculated weekly prevalence, incidence, and burden of groin injuries. The team physical therapists classified the player-reported injuries based on the Doha classification system. Injuries with more than 3 days' time loss or reported in 2 consecutive weeks were eligible for magnetic resonance imaging (MRI). RESULTS: On average, 3.9% (95% CI: 3.4-4.4) of players reported a groin injury at any time; of which 78% caused time loss. The incidence rate was 1.6 injuries/1000 h (95% CI: 1.3-2.0) and their burden was 11 days lost/1000 h. The physical therapists examined 67 of 124 player-reported groin injuries (53%). Adductor-related injury was most common (55%) followed by iliopsoas (15%) and rectus femoris-related (12%). Pubic-related injuries caused most time loss (median: 24 days, IQR: 5-133). In this study, 42 injuries were investigated with MRI; 8 (19%) showed no changes, 6 (14%) an acute musculotendinous lesion, and 32 (76%) a nonacute finding (e.g., central symphyseal disc protrusion, tendinopathies). CONCLUSION: The incidence rate and burden of groin injuries were high. Adductor-related injuries were most common, but pubic-related injuries caused most time loss. Most MRI examinations demonstrated nonacute findings.

All groin swellings are not lipoma.

An interesting case of an abdominal wall swelling near an old operative scar showing epithelial and stromal cells. In this present paper, fine needle aspiration cytology of an inguinal swelling is discussed which may often create diagnostic confusion.

Intra-obturator bupivacaine injection and post-operative pain following the trans-obturator tension-free vaginal tape procedure: randomized study.

PURPOSE: To assess the effectiveness of a long-acting anesthetic injection into the obturator membrane for pain relief in women undergoing trans-obturator tension-free vaginal tape. METHODS: A total of 22 women were randomized for the intra-operative injection of bupivacaine into one of their obturator membranes: the left or right side. All the participants were asked to define their groin pain on a visual analog scale (scored 0-10 cm) at 1, 6, 12, and 24 h post-operative. For each woman, pain scores were compared between the local anesthetic-injected side and the opposite side. RESULTS: Statistically significant differences were not observed in groin pain scores between the bupivacaine injection side and the no injection side at 1 h (p = 0.76), 6 h (p = 1), 12 h (p = 0.95), and 24 h (p = 0.82) post-operative. CONCLUSION: In women who undergo trans-obturator tension-free vaginal tape procedures, intra-operative intra-obturator injection of local anesthetics is not effective in alleviating the characteristic post-operative groin pain. TRIAL REGISTRATION: This study is registered on ClinicalTrials.gov (NCT03479996).

High Prevalence of Seasonal and Current Groin Problems in Rink Hockey Players.

Groin problems are common in multidirectional sports. The aim of the present study is to assess seasonal, current, and trends for groin problems in rink hockey players, irrespective of their playing position, age, or gender. Rink hockey players from three countries [n=446 (162 female, 284 male)] were invited to participate in an online questionnaire. This form evaluated the prevalence of groin problems (time-loss and non-time-loss) for the 2022-2023 season, as well as monthly prevalence of groin problems (time-loss and non-time-loss). All groin problems were compared between playing position, gender, and age to assess between-group differences. Senior males reported the highest time-loss (25%) and non-time-loss (51%) for seasonal prevalence; while U-17 males reported the lowest in both categories of groin problems (time-loss 9%, non-time-loss 27%). No significant differences between playing position or gender were found for any of the groin problems analyzed. In-season prevalence (9-15.7%) of groin problems was significantly higher than pre-season (7.4%) prevalence (p<0.01). Seasonal prevalence of groin problems is common in rink hockey, regardless of gender, playing position, or age. Preventive efforts should be directed towards all players, regardless of their individual characteristics.

The Utility of Prevena Negative Pressure Wound Therapy on Groin Incisions for Critical Limb-Threatening Ischemia: A Single Institution Experience.

BACKGROUND: Incisional negative pressure wound therapy (iNPWT) is an adjunctive treatment that uses constant negative pressure suction to facilitate healing. The utility of this treatment modality on vascular operations for critical limb-threatening ischemia (CLTI) has yet to be elucidated. This study compares the incidence of postoperative wound complications between the Prevena Incision Management System, a type of iNPWT, and standard wound dressings for vascular patients who also underwent plastic surgery closure of groin incisions for CLTI. METHOD: We performed a retrospective cohort study of 40 patients with CLTI who underwent 53 open vascular surgeries with subsequent sartorius muscle flap closure. Patient demographics, intraoperative details, and wound complications were measured from 2015 to 2018 at the University of California San Francisco. Two cohorts were generated based on the modality of postoperative wound management and compared on wound healing outcomes. RESULTS: Of the 53 groin incisions, 29 were managed with standard dressings, and 24 received iNPWT. Patient demographics, comorbidities, and operative characteristics were similar between the 2 groups. Patients who received iNPWT had a significantly lower rate of infection (8.33% vs 31.0%, P = 0.04) and dehiscence (0% vs 41.3%, P < 0.01). Furthermore, the iNPWT group had a significantly lower rate of reoperation (0% vs 17.2%, P = 0.03) for wound complications within 30 days compared with the control group and a moderately reduced rate of readmission (4.17% vs 20.7%, P = 0.08). CONCLUSIONS: Rates of infection, reoperation, and dehiscence were significantly reduced in patients whose groin incisions were managed with iNPWT compared with standard wound care. Readmission rates were also decreased, but this difference was not statistically significant. Our results suggest that implementing iNPWT for the management of groin incisions, particularly in patients undergoing vascular operations for CLTI, may significantly improve clinical outcomes.

Predictors of complication after groin dissection: a single-centre experience.

BACKGROUND: Inguinal lymphadenectomy (ILND) has historically been associated with substantial morbidity. The objective of this study was to obtain contemporary ILND morbidity rates and to identify potentially preventable risk factors. METHODS: We carried out a retrospective review of medical records for all superficial, deep, and combination groin dissections performed at a single, high-volume academic centre between January 2007 and December 2020. We collected data points for patient, disease, and surgery characteristics, and cancer outcomes. The outcome of interest was any complication within 30 days of surgery. Complications included wound infection, wound necrosis or disruption, seroma, drainage procedure, hematoma, and lymphedema. We performed multivariate logistic regression using SAS version 9.4. RESULTS: We identified 139 patients having undergone 89 superficial, 12 deep, and 38 combined dissection types, respectively. Melanoma accounted for 84.9% of cases. Of these patients, 56.1% had an adverse postoperative event within 30 days. Increasing age (odds ratio [OR] 1.04, 95% confidence interval [CI] 1.01-1.07, p < 0.01) and number of positive lymph nodes harvested (OR 1.22, 95% CI 1.00-1.50, p = 0.05) were associated with more complications. Patients with deep dissection showed a lower likelihood of complications than those with superficial dissection (OR 0.15, 95% CI 0.03-0.84, p < 0.05). CONCLUSION: Complication rates after ILND remain high. We identified a number of risk factors, providing opportunities for better selection and prevention.

Intranodal embolization for lymphocele after revascularization procedure in the groin.

Early postoperative wound complications in revascularization procedures in the groin very often include complications associated with injury to the lymphatic system such as lymphocele and lymphorrhea with subsequent local infectious complications and the risk of infection of prosthetic grafts. We present a case report of successful treatment of postoperative lymphocele with subsequent lymphatic fistula and dehiscence of the surgical wound by intranodal embolization of the injured lymph node with Histoacryl tissue glue.

Paraperitoneal inguinal hernia of ureter.

INTRODUCTION: The ureter is present in surgical field during inguinal hernia repair in 0.5-4% of cases. It typically occurs in obese patients, in men and patients after kidney transplants. Right-sided and indirect location of ureteral herniation prevails. The clinical picture is mostly asymptomatic, but possible manifestations include increased frequency of urination with urgency, nocturia, recurrent pyelonephritis, urosepsis, feeling of incomplete emptying of the bladder, signs of GIT obstruction. Diagnostic methods include retrograde pyelography or CT urography. Surgical treatment is indicated in every case of ureteral herniation. Reposition of the ureter retroperitoneally and standard plasty of the inguinal canal is the method of choice. METHODS: 33 cases of ureteral hernia were reviewed in order to write a systematized review of the topic. The case report describes a 68-year-old patient with prostatic hyperplasia and dysuria treated at our institution. A preoperative CT examination with intravenous contrast showed herniation of the right ureter into the inguinal area with hydronephrosis of 2nd degree. Preoperative insertion of a mono-J stent into the right ureter and reposition of the ureter retroperitoneally followed by hernia repair using alloplastic material was performed. There were no postoperative complications. RESULTS AND CONCLUSION: In risky cases, the surgeon should assume the possible presence of a ureter in the inguinal region. Careful dissection in the inguinal area reduces the risk of iatrogenic damage to the ureter.

Groin Pain Syndrome Italian Consensus Conference update 2023.

Groin pain syndrome (GPS) is a controversial topic in Sports Medicine. The GPS Italian Consensus Conference on terminology, clinical evaluation and imaging assessment of groin pain in athletes was organized by the Italian Society of Arthroscopy in Milan, on 5 February 2016. In this Consensus Conference (CC) GPS etiology was divided into 11 different categories for a total of 63 pathologies. The GPS Italian Consensus Conference update 2023 is an update of the 2016 CC. The CC was based on a sequential, two-round online Delphi survey, followed by a final CC in the presence of all panelists. The panel was composed of 55 experts from different scientific and clinical backgrounds. Each expert discussed 6 different documents, one of which regarded the clinical and imaging definition of sports hernias, and the other 5 dealt with 5 new clinical situations thought to result in GPS. The panelists came to an agreement on the definition of a sports hernia. Furthermore, an agreement was reached, recognizing 4 of the 5 possible proposed pathologies as causes to GPS. On the contrary, the sixth pathology discussed did not find consensus given the insufficient evidence in the available scientific literature. The final document includes a new clinical and imaging definition of sports hernia. Furthermore, the etiology of GPS was updated compared to the previous CC of 2016. The new taxonomic classification includes 12 categories (versus 11 in the previous CC) and 67 pathologies (versus 63 in the previous CC).
