Optimised return to play: high treatment success rate in core muscle injury with surgical release of the anterior tendon of the rectus abdominis muscle and proximal tenotomy of the adductor longus muscle.

OBJECTIVES: Core muscle injury is a debilitating condition that causes chronic groin pain in athletes, particularly common in soccer players. The condition is characterised by pain in the inguinal region and can lead to a significant number of absences from high-intensity physical activity. It is caused by repetitive overload without proper counterbalance from the abdominal muscles, hip flexors, and adductors in susceptible athletes. Surgical indications for core muscle injury consider cases where non-surgical treatments have not provided sufficient relief. The aim of this study was to assess the results of surgical intervention for core muscle injury using the technique employed by the Sports Medicine Group of (Institute of Orthopedics and Traumatology of Hospital das Clínicas - Universidade de São Paulo). The procedure involves releasing the anterior portion of the tendon of the rectus abdominis muscle near the pubic symphysis, along with proximal tenotomy of the adductor longus muscle tendon. METHODS: This study utilised a consecutive historical cohort analysis of the medical records of 45 male athletes, of which, 75.6% were professional soccer players, who underwent surgical treatment between January 1, 2002, and December 31, 2021. The participants included active athletes aged between 18 and 40 years, with a mean age of 23.9 years, and were diagnosed with myotendinous core muscle injury. These athletes experienced pain in the pubic symphysis and adductor tendon region and had previously undergone medical treatment and physical therapy for a duration of three to six months without significant improvement. RESULTS: The average time for athletes to return to sport after surgery was 135 days, with a majority of participants being soccer and futsal players. The surgical intervention yielded promising results, with a positive correlation between unilateral injuries and the time taken to return to sport. The complication rate was low, at 6.7%. Notably, the rate of symptom resolution was high, at 93.3%. Furthermore, the analysis indicated that the player's position on the field significantly influenced the discharge period, suggesting that the game position plays a role in the recovery process. CONCLUSION: The combined surgical procedure involving the release of the rectus abdominis tendon and adductor longus muscle tenotomy demonstrates favourable outcomes for athletes with core muscle injury. This study provides strong support for the effectiveness of this surgical approach in managing the condition and offers a potential path to recovery and return to sports activities. STUDY DESIGN: Cross-sectional study.

Core Muscle Injury: Evaluation and Treatment in the Athlete.

BACKGROUND: Pain in the groin region, where the abdominal musculature attaches to the pubis, is referred to as a "sports hernia,""athletic pubalgia," or "core muscle injury" and has become a topic of increased interest due to its challenging diagnosis. Identifying the cause of chronic groin pain is complicated because significant symptom overlap exists between disorders of the proximal thigh musculature, intra-articular hip pathology, and disorders of the abdominal musculature. PURPOSE: To present a comprehensive review of the pathoanatomic features, history and physical examination, and imaging modalities used to make the diagnosis of core muscle injury. STUDY DESIGN: Narrative and literature review; Level of evidence, 4. METHODS: A comprehensive literature search was performed. Studies involving the diagnosis, treatment, and rehabilitation of athletes with core muscle injury were identified. In addition, the senior author's extensive experience with the care of professional, collegiate, and elite athletes was analyzed and compared with established treatment algorithms. RESULTS: The differential diagnosis of groin pain in the athlete should include core muscle injury with or without adductor longus tendinopathy. Current scientific evidence is lacking in this field; however, consensus regarding terms and treatment algorithms was facilitated with the publication of the Doha agreement in 2015. Pain localized proximal to the inguinal ligament, especially in conjunction with tenderness at the rectus abdominis insertion, is highly suggestive of core muscle injury. Concomitant adductor longus tendinopathy is not uncommon in these athletes and should be investigated. The diagnosis of core muscle injury is a clinical one, although dynamic ultrasonography is becoming increasingly used as a diagnostic modality. Magnetic resonance imaging is not always diagnostic and may underestimate the true extent of a core muscle injury. Functional rehabilitation programs can often return athletes to the same level of play. If an athlete has been diagnosed with athletic pubalgia and has persistent symptoms despite 12 weeks of nonoperative treatment, a surgical repair using mesh and a relaxing myotomy of the conjoined tendon should be considered. The most common intraoperative finding is a deficient posterior wall of the inguinal canal with injury to the distal rectus abdominis. Return to play after surgery for an isolated sports hernia is typically allowed at 4 weeks; however, if an adductor release is performed as well, return to play occurs at 12 weeks. CONCLUSION: Core muscle injury is a diagnosis that requires a high level of clinical suspicion and should be considered in any athlete with pain in the inguinal region. Concurrent adductor pathology is not uncommon.

Prepubic aponeurotic complex injuries: a structured narrative review.

The prepubic aponeurotic complex anatomy (PPAC) consists in a fibrous capsule, which anteriorly lines the pubic symphysis, formed by the interconnection of different anatomical structures. Research of the studies (original articles, case series and review articles) was conducted without publication data limitation or language restriction on the following databases: PubMed/MEDLINE, Scopus, ISI, EXCERPTA. To date, evidence from the literature suggests that: 1) the PPAC is formed by interconnection between the tendons of the adductor longus, adductor brevis, gracilis and pectineus muscles, the aponeurosis of rectus abdominis, pyramidalis and external oblique muscles, the articular disc, the anterior pubic periostium and by the superior, inferior and anterior pubic ligament; 2) the PPAC clinical presentation may mimic a adductor longus tendon injury, the MRI examination can help to differentiate the two different clinical frameworks; 3) the PPAC injuries show a typical MRI presentation which must be differentiated from other similar but clinically different imaging frameworks; 4) the PACC injury can be treated conservatively, with medical therapies or surgically. This narrative structured review provides an insight into the PPAC the anatomy, the clinical presentation, the imaging and the treatment of the PPAC injuries.

Ultrasound-guided Procedures Allow Delay of Definitive Treatment for Core Muscle Injuries.

INTRODUCTION: Core muscle injuries (CMI) are common in every sport. To minimize lost playing time, providers apply various nonsurgical treatments, including platelet-rich plasma, corticosteroids, ultrasound (US)-guided percutaneous tenotomy, and prolotherapy. Limited data exist with regard to their effectiveness. We chose to review a cohort of consecutive professional and collegiate athletes who sustained CMI at various points within their seasons and underwent a combination of US-guided percutaneous needle "tenotomy" and corticosteroid injections to complete the remainder of their seasons. METHODS: Twenty-five consecutive collegiate or professional athletes with CMI involving the rectus abdominis-adductor aponeurotic plate were included in this retrospective study. Athletes with concomitant symptomatic hip femoroacetabular impingement were included in the study. The primary outcome measure was whether athletes completed their seasons. Secondary measures were weeks played after the procedures (delay until surgery), need for repeat procedures, and outcomes after eventual surgery. Postoperative performance was assessed via interviews at 6 wk and 6 months postoperatively. RESULTS: Twenty-one of 25 (84%) athletes completed their seasons. On average, athletes returned to play 3 d (range, 1-9 d) after the procedures. Surgical repair was delayed a mean of 18 wk (range, 2-44 wk). Seven athletes had concomitant symptomatic femoroacetabular impingement and six underwent combined hip arthroscopy and core muscle repairs. Among 17 patients who eventually had core muscle surgery alone (no hip surgery), 82% (14 of 17) reported performing at their preinjury level at 6 wk. At 6 months, 96% of postop athletes (22 of 23) reported performing at their preinjury level. CONCLUSIONS: Temporizing CMI with US-guided percutaneous tenotomy and corticosteroid injections is effective in allowing continued sport participation among high-level athletes and does not negatively affect postoperative outcomes.

Stretch too far: rectus sheath haematoma secondary to repetitive trauma and increased intra-abdominal pressure.

A 26-year-old man presented with a 4-week history of right lower quadrant abdominal pain which was managed conservatively at home with ibuprofen. Three days later, he presented to the emergency department with worsening pain and swelling following an episode of coughing and slipping in the bathroom. Following his admission, CT angiography showed an active bleed into a 4.6×6.7×11 cm right rectus sheath haematoma, just inferior to the umbilicus. The patient was then referred to interventional radiology for an angiogram and coil embolisation. A superselective branch angiogram showed contrast extravasation from a medial branch of the right inferior epigastric artery, successfully embolised without incident.

Athletic Pubalgia (Sports Hernia): Presentation and Treatment.

Often referred to as a "sports hernia" or "core muscle injury," athletic pubalgia is a common yet poorly defined athletic injury. It is characterized by abdominal and groin pain likely from weakening or tearing of the abdominal wall without evidence of a true hernia. Symptoms can appear acutely or insidiously, primarily as groin and lower abdominal pain that can radiate toward the perineum and proximal adductors. Pain is exacerbated by athletic activity such as kicking, cutting, and sprinting. The pubis acts as a pivot point between the abdominal musculature and lower-extremity adductors, and therefore, pain with palpation over the symphysis or its surrounding structures is typical in athletic pubalgia. Symptoms can be reproduced during a resisted sit-up or with a forced cough or sneeze. Clinical examination should include an evaluation of articular hip pathology to identify underlying femoroacetabular impingement syndrome. Magnetic resonance imaging can aid in ruling out other pathologies and identify specific findings including tears or strains of the ipsilateral rectus abdominis or adductor tendons. Lidocaine injections can be used to localize the source of the pain. First-line treatment consists of a period of rest and anti-inflammatories, followed by a course of focused physical therapy. If conservative therapy fails to allow an athlete to return to activity, a variety of open or laparoscopic surgical techniques can be used. The surgical principles include reattachment of the rectus abdominis and repair or reinforcement of the abdominal musculature in layers to re-create the inguinal ligament anatomy. At times, variations of pelvic floor repair are performed or the addition of an adductor tenotomy or repair is used concomitantly. Numerous studies report a high rate of return to play after surgical management. Diagnosis and appropriate treatment of coexisting femoroacetabular impingement syndrome are crucial to a successful return to athletic activity.

Surgical Repair of Bilateral Combined Rectus Abdominis and Adductor Longus Avulsion: A Case Report.

CASE: In this case report, we present an adult man who sustained bilateral rectus abdominis and adductor longus avulsions with associated symphyseal instability while playing hockey. The injury was managed surgically, and the patient returned to preinjury level of function. CONCLUSION: To our knowledge, this is the first reported case of such a bilateral injury. The surgical management and outcome add to the current literature, which lacks adequate evidence on the most effective management for injuries of this type.

Diagnostic Accuracy of Physical Examination Tests in Core Muscle Injury.

BACKGROUND: Core muscle injury (CMI), often referred to as a sports hernia, is a common cause of groin pain in athletes characterized by concomitant injury to the insertion of the adductor longus and the rectus abdominis muscles. Currently, the literature on CMI is sparse with no standardized physical examination tests used in the diagnosis of this type of injury. PURPOSE: To determine the diagnostic accuracy of various physical examination tests in the diagnosis of CMI. STUDY DESIGN: Cohort study (Diagnosis); Level of evidence, 3. METHODS: A consecutive series of patients evaluated by the senior author with symptoms consistent with CMI were included. Four physical examination tests were routinely performed in these patients by the senior author and were noted in each patient's chart as positive or negative: (1) pain with resisted cross-body sit-up in figure-of-4 position, (2) pain with straight-leg sit-up, (3) pain with resisted hip flexion in external rotation (external rotation Stinchfield test), and (4) the presence of an adductor contracture. CMI was independently diagnosed by a reference standard (magnetic resonance imaging [MRI]). All MRI scans were read by a musculoskeletal fellowship-trained radiologist. The sensitivity and specificity of each physical examination test alone and in combination were calculated based on this reference standard. RESULTS: A total of 81 patients were included in this study. MRI was positive for a CMI in 39 patients (48%) overall. Both the cross-body sit-up test and the presence of an adductor contracture were found to have a sensitivity of 100% (specificity, 3% for both). The external rotation Stinchfield test was found to have the highest specificity of 60% (sensitivity, 15%). The sensitivity of all 4 physical examination tests in combination was found to be 100% (specificity, 0%). CONCLUSION: Certain physical examination maneuvers can be used to assist in the diagnosis of a CMI. The cross-body sit-up test and the presence of an adductor contracture are highly sensitive but nonspecific tests for CMI and therefore should be used in conjunction with diagnostic imaging before deciding on an appropriate treatment course.

Rectus abdominis muscle tear diagnosed with sonography and its conservative management.

PURPOSE: This is a rare case of a post-traumatic rectus abdominis muscle tear in an adolescent female diagnosed by ultrasonography (US). Conservative management is also described. METHODS: A 14-year-old female presented to a chiropractic clinic with extreme pain and tenderness in the right lower quadrant (RLQ) after post-plyometric power kneel box jumps. Movement aggravated her pain and she demonstrated active abdominal guarding with RLQ palpation. Ultrasonography revealed a subacute Grade 2 right rectus abdominis muscle tear, without evidence of hyperemia or a hematoma. Following the diagnosis of a right rectus abdominis muscle tear, she was treated with spinal manipulation and a course of musculoskeletal rehabilitation directed at truncal stabilization. RESULTS: After treatment, the patient was able to return to play 5 week post-injury without any pain or discomfort. A follow-up US at 3 months provided evidence of muscle healing without complications. CONCLUSION: This case demonstrates the diagnosis of a rare rectus abdominis muscle tear managed conservatively. To our knowledge, less than a dozen cases are reported using US in the evaluation and diagnosis of a rectus abdominis tear.

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.

Abdominal Wall Plication and Correction of Deformities of the Myoaponeurotic Layer: Focusing on Materials and Techniques Used for Synthesis.

The different types of sutures utilized in plications and for correction of diastasis during abdominoplasty are reviewed and discussed. Because correction of abdominal deformities also involves fascia and muscle advancement, this review also covers the suture materials used in muscle advancement. The selection of specific techniques to treat different types of abdominal wall deformity is also considered. This is important, because the outcome when correcting these deformities depends not only on suture materials but also on employing the optimum technique. A PubMed/Medline search was performed with the following search terms: rectus diastasis, diastasis recti, diastasis recti abdominis, correction of rectus diastasis, abdominoplasty. Relevant articles identifying the type of suture (rapidly absorbable, slowly absorbable, nonabsorbable), monofilament or multifilament sutures, antibiotic-coated sutures, and barbed sutures were evaluated. In addition, articles about surgical technique comparing continuous and interrupted sutures, in both the anterior and posterior aponeurosis, to correct rectus diastasis are discussed. Efficacy of suture materials was evaluated based on the long-term results and recurrence rates reported in these articles. The current literature provides sufficient data to recommend a single-layer continuous suture, with slowly absorbable sutures of 0 polydioxanone or 2-0 nylon, for correction of abdominal diastasis. An interrupted triangular suture is a good alternative to correct the vertical elongation of the myoaponeurotic layer that occurs after pregnancy.

Bladder perforation secondary to rectus sheath hematoma after enoxaparin injection.

Rectus sheath hematoma is a collection of blood in the sheath of rectus abdominis muscle due to an injury of one of the epigastric vessels or the muscle itself. It is a rare condition that could be caused by the use of anticoagulant injections. We report a 60-year-old lady who received enoxaparin injection on the lower abdomen. Subsequently, she developed bladder perforation secondary to rectus sheath hematoma and was diagnosed using CT angiography scan. Exploratory laparotomy was performed and bleeding was controlled with bladder wall repair. Patient developed multi-organ failure. Three days later, the patient died. Rectus sheath hematoma is a rare condition and it is often associated with the use of anticoagulant injection. Healthcare providers should be aware of such complication for prevention and early diagnosis.

Introduction: The rectus abdominis (RA), is a pair, curved muscle, whose main functions are trunk flexion and Core stability. His strain is associated with the sport of elite and pitchers, mostly linked to tennis and its service according to publications. In volleyball, cycles of hyperextension of the trunk with eccentric sebrecharge and consequent asymmetric hypertrophy of the RA contralateral to the dominant arm, seat of the muscle injury, are repeated. Materials and methods: A descriptive, retrospective study of a series of reasons for consultation of players of the Argentine National Men's Volleyball Team during the period between 2015 and 2017 was carried out. The injuries were classified according to the return to sport criteria by Páus V. and Torrengo F. The athletes with RA strain were grouped evaluating following variables: Dominant arm, injured RA, type of muscle injury, sports gesture involved, competition situation at injury time, previous abdominal lesion. Results: We evaluated 386 reasons for consultation, the central players were the most consulted, in the general context of injuries were classified the 10 main reasons for consultation, muscle functional injuries (contractures) were the most frequent (n97, 25%), the RA strain was the predominant structural muscle lesion above the gastrocnemius. 6 case of acute injury and 1 case of recurrence. most during the attack gesture and in competition. Conclusion: From the analyzed in the registers the muscular injury represented 42% of the total of the injuries, the strain has predominance in the rectus abdominus representing 32% of the total of the muscular structural injuries.

Rectus Abdominis Rhabdomyolysis: Report of 2 Cases.

Exercise-induced rhabdomyolysis is an unusual clinical entity for physicians and one that is frequently misdiagnosed. With the ever-increasing use of sonography by radiologists, sonographers, and sports physicians in the diagnosis of acute muscle injury, recognition of the typical sonographic appearance of rhabdomyolysis is paramount. Current literature using high-resolution ultrasound equipment is limited, with much of the literature offering dated or incongruent descriptions. We describe the sonographic findings of hyperechoic muscle and a hypoechoic halo of edema in 2 proven cases of rectus abdominis rhabdomyolysis after exercise.

Sports hernia repair with adductor tenotomy.

PURPOSE: Sports hernias, or athletic pubalgia, is common in athletes, and primarily involves injury to the fascia, muscles, and tendons of the inguinal region near their insertion onto the pubic bone. However, management varies widely, and rectus and adductor tenotomies have not been adequately described. The purpose of this manuscript is to demonstrate a suture repair and a rectus and adductor longus tenotomy technique for sports hernias. METHODS: After magnetic-resonance-imaging confirmation of sports hernias with rectus and adductor tendonitis, 22 patients underwent a suture herniorrhaphy with adductor tenotomy. The procedure is performed through a 4-cm incision, and a fascial release of the rectus abdominis and adductor tenotomy is performed to relieve the opposing vector forces on the pubic bone. RESULTS: All 22 patients returned to their respective sports and regained their ability to perform at a high level, including professional status. No further surgery was required. CONCLUSION: In athletes with MRI confirmation of rectus and adductor longus injuries, tenotomies along with a herniorraphy may improve outcomes. A suture repair to reinforce the inguinal floor prevents mesh-related complications, especially in young athletes.

Modeling Acinetobacter baumannii wound infections: The critical role of iron.

BACKGROUND: Acinetobacter baumannii has emerged as an increasingly important and successful opportunistic human pathogen due to its ability to withstand harsh environmental conditions, its characteristic virulence factors, and quick adaptability to stress. METHODS: We developed a clinically relevant murine model of A. baumannii traumatic wound infection to determine the effect of local wound environment on A. baumannii virulence. Mice underwent rectus muscle crush injury combined with ischemia created by epigastric vessel ligation, followed by A. baumannii inoculation. Reiterative experiments were performed using (1) a mutant deficient in the production of the siderophore acinetobactin, or (2) iron supplementation of the wound milieu. Mice were euthanized 7 days later, and rectus muscle analyzed for signs of clinical infection, HIF1α accumulation, bacterial abundance, and colony morphotype. To determine the effect of wound milieu on bacterial virulence, Galleria mellonella infection model was used. RESULTS: The combination of rectus muscle injury with ischemia and A. baumannii inoculation resulted in 100% incidence of clinical wound infection that was significantly higher compared with other groups (n = 15/group, p < 0.0001). The highest level of wound infection was accompanied by the highest level of A. baumannii colonization (p < 0.0001) and the highest degree of HIF1α accumulation (p < 0.05). A. baumannii strains isolated from injured/ischemic muscle with clinical infection displayed a rough morphotype and a higher degree of virulence as judged by G. mellonella killing assay as compared with smooth morphotype colonies isolated from injured muscle without clinical infection (100% vs. 60%, n = 30 Log-Rank test, p = 0.0422). Iron supplementation prevented wound infection (n = 30, p < 0.0001) and decreased HIF1α (p = 0.039643). Similar results of decrease in wound infection and HIF1α were obtained when A. baumannii wild type was replaced with its derivative mutant [INCREMENT]BasD deficient in acinetobactin production. CONCLUSION: The ability of A. baumannii to cause infections in traumatized wound relies on its ability to scavenge iron and can be prevented by iron supplementation to the wound milieu.

Rehabilitation and Return to Sport Following Surgical Repair of the Rectus Abdominis and Adductor Longus in a Professional Basketball Player: A Case Report.

Study Design Case report. Background Acute traumatic avulsion of the rectus abdominis and adductor longus is rare. Chronic groin injuries, often falling under the athletic pubalgia spectrum, have been reported to be more common. There is limited evidence detailing the comprehensive rehabilitation and return to sport of an athlete following surgical or conservative treatment of avulsion injuries of the pubis or other sports-related groin pathologies. Case Description A 29-year-old National Basketball Association player sustained a contact injury during a professional basketball game. This case report describes a unique clinical situation specific to professional sport, in which a surgical repair of an avulsed rectus abdominis and adductor longus was combined with a multimodal impairment- and outcomes-based rehabilitation program. Outcomes The patient returned to in-season competition at 5 weeks postoperation. Objective measures were tracked throughout rehabilitation and compared to baseline assessments. Measures such as the Copenhagen Hip and Groin Outcome Score and numeric pain-rating scale revealed progress beyond the minimal important difference. Discussion This case report details the clinical reasoning and evidence-informed interventions involved in the return to elite sport. Detailed programming and objective assessment may assist in achieving desired outcomes ahead of previously established timelines. Level of Evidence Therapy, level 4.
