Sports hernia: diagnosis and therapeutic approach

Groin pain is a common entity in athletes involved in soccer, ice hockey, Australian Rules football, skiing, running, and hurdling. An increasingly recognized cause of groin pain in these athletes is a sports hernia, an occult hernia caused by weakness or tear of the posterior inguinal wall, without a clinically recognizable hernia, that leads to a condition of chronic groin pain. The patient typically presents with an insidious onset of activity-related, unilateral, deep groin pain that abates with rest. Although the physical examination reveals no detectable inguinal hernia, a tender, dilated superficial inguinal ring and tenderness of the posterior wall of the inguinal canal are found. The role of imaging studies in this condition is unclear; most imaging studies will be normal. Unlike most other types of groin pain, sports hernias rarely improve with nonsurgical measures; thus, open or laparoscopic herniorrhaphy should be considered.     

Identification of abnormal hip motion associated with acetabular labral pathology

STUDY DESIGN: Resident's case problem. BACKGROUND: Recent literature has suggested that acetabular labral pathology secondary to femoroacetabular impingement (FAI) may be a precursor to early-onset hip osteoarthritis. The purpose of this resident's case problem was to explore the extent to which abnormal movement at the hip is a possible contributor to acetabular labral pathology. DIAGNOSIS: The patient was a 25-year-old female with a 4-year history of anterior-medial groin pain. Based on a combination of the clinical examination and magnetic resonance imaging findings, she was given a diagnosis of acetabular labral tear by her orthopaedic surgeon and referred to a physical therapist for assessment. Movement analysis during a single-leg step down, running, and a drop jump maneuver revealed excessive hip adduction and internal rotation on the involved side, which reproduced her symptoms. Application of a hip-strapping device resulted in decreased hip adduction and internal rotation, and an immediate decrease in symptoms. DISCUSSION: The reduction in pain secondary to controlling hip motion suggests that excessive frontal and transverse plane hip motions may contribute to FAI. Accordingly, physical therapy intervention aimed at controlling and reducing hip adduction and internal rotation during activities may be indicated in patients who present with this movement pattern associated with anterior hip/groin pain.

Ultrasound of the inguinal floor for evaluation of hernias

BACKGROUND: This study aimed to evaluate the utility of ultrasound in the diagnosis of inguinal hernias and obscure groin pain. METHODS: A series of 65 consecutive groin explorations performed subsequently to percutaneous ultrasound examination were prospectively evaluated. Patients were examined in an office setting. The examination included a history and a physical. Then an ultrasound of the inguinal region was performed. Ultrasound was performed by the staff surgeon and fellows. Patients then were taken to surgery for either a laparoscopic or open hernia repair. The preoperative and operative findings were compared to determine the utility of groin ultrasound. RESULTS: A series of 41 patients presenting with symptoms of groin pain or palpable groin bulge were evaluated with ultrasound of the groin. Of these patients, 24 went on to have bilateral repairs, bringing the study total to 65 groins. Surgery involved 50 laparoscopic and 15 open hernia repairs. This included 20 groins without hernia, as determined by physical examination, and 45 groins with a palpable hernia. Overall, ultrasound was used to identify the type of hernia correctly (direct vs indirect) with 85% success. In the 20 patients who had no palpable bulge, ultrasound identified a protrusion (hernia or lipoma) in 17. Two of these were false positives, and the three negative ultrasound examinations were false negatives. Thus ultrasound identified the pathology in a groin without a palpable bulge at an accuracy of 75%. The overall accuracy in finding a hernia of any kind by ultrasound was 92%. CONCLUSION: Ultrasound is a useful adjunct in evaluating the groin for hernia, and can be performed by surgeons.     

Abdominal differential diagnosis in a patient referred to a physical therapy clinic for low back pain

STUDY DESIGN: Resident's case problem. BACKGROUND: Acute back pain most often presents as musculoskeletal in nature; however, less frequently it may be the result of an underlying, or coexisting, systemic pathology. When present, the signs and symptoms of systemic pathology can mimic, or be masked by, musculoskeletal back pain, which may pose a diagnostic challenge during the clinical evaluation. The purpose of this resident's case problem is to describe the clinical reasoning process leading to a medical referral for a patient who presented to physical therapy with debilitating low back pain. DIAGNOSIS: The patient in this resident's case problem was a 67-year-old male referred to physical therapy with a 2-week history of severe low back pain and muscle spasms. The patient history and physical examination were suggestive of musculoskeletal back pain and physical therapy treatment was initiated. Abdominal pain was elicited during an introductory therapeutic exercise, which was recognized by the therapist as a potential sign of abdominal pathology. The therapist performed an additional review of systems and an abdominal screening examination, which established the necessity of an immediate medical referral. At the emergency department, ominous abdominal pathology was safely ruled out through diagnostic imaging and the patient was treated for secondary gastrointestinal effects of opioid analgesic medications. DISCUSSION: This resident's case problem provides an opportunity to discuss the clinical reasoning process leading to the suspicion of abdominal pathology. Specifically, this case reinforces the importance of recognizing potential signs of systemic pathology, executing an appropriate physical examination, including screening of the involved anatomical region, and providing an appropriate medical referral when indicated.     

Sportsman's hernia

BACKGROUND: Sportsman's hernia is a debilitating condition which presents as chronic groin pain. A tear occurs at the external oblique which may result in an occult hernia. The definition, investigation and treatment of this condition remain unclear. METHODS: A systematic Medline search was performed and all literature pertaining to chronic groin pain, groin injury, sportsman's hernia and sportsman's groin from 1962 to 1999 was retrieved for analysis. RESULTS: The costs of computed tomography and magnetic resonance imaging are such that their routine use for assessment of patients with groin pain cannot be justified. They may, however, be employed in difficult cases to help define the anatomical extent of a groin injury. Plain radiography, ultrasonography and scintigraphy should be the usual first-line investigations to supplement clinical assessment. Herniography may help in situations of obscure chronic groin and pelvic pain. There is no consensus view supporting any particular surgical procedure for sportsman's hernia. A number of reports have been published describing different repairs of the posterior inguinal wall deficiency. Appropriate repair of the posterior wall results in therapeutic benefit in selected cases. CONCLUSION: The diagnosis of sportsman's hernia is difficult. The condition must be distinguished from the more common osteitis pubis and musculotendinous injuries. Early surgical intervention is usually, although not always, successful when conservative management has failed.     

Pain and functional impairment 1 year after inguinal herniorrhaphy: a nationwide questionnaire study

OBJECTIVE: To determine the incidence of groin pain 1 year after inguinal herniorrhaphy and to assess the influence of chronic groin pain on function. SUMMARY BACKGROUND DATA: The reported incidence of chronic pain after inguinal herniorrhaphy varies from 0% to 37%. No cross-sectional cohort studies with high follow-up rates have addressed this problem, and there is a lack of assessment of the functional consequences of chronic groin pain after herniorrhaphy. METHODS: Two sets of self-administered questionnaires were mailed 1 year after surgery. The first established the incidence of chronic groin pain. The second characterized the pain and the effect of the pain on the function of those reporting pain. The study population comprised patients older than age 18 years registered in the Danish Hernia Database who underwent surgery between February 1, 1998, and March 31, 1998. RESULTS: The response rate to the first questionnaire was 80.8%. Pain in the groin area was reported by 28.7%, and 11.0% reported that pain was interfering with work or leisure activity. Older patients had a lower incidence of pain. There were no differences in the incidence of pain with regard to the different types of hernia, the different types of surgical repairs, or the different types of anesthesia. The second questionnaire was returned by 83%. Of these, 46 (4%) reported constant pain. The intensity of pain while at rest was moderate or severe in 40 (3%); with physical activity, pain was moderate or severe in 91 (8%). Impairment of specific daily activities as a result of pain was reported by 194 (16.6%). Pain characteristics were predominantly sensory, with a low use of affective terms. CONCLUSION: One year after inguinal hernia repair, pain is common (28.7%) and is associated with functional impairment in more than half of those with pain. These factors should be addressed when discussing the need for surgical intervention for an inguinal hernia.     

Inguinal neurectomy for inguinal nerve entrapment: an experience with 100 patients

BACKGROUND: Inguinal nerve entrapment is a debilitating postoperative problem. PATIENTS AND METHODS: One hundred patients were treated for inguinal nerve entrapment, including 52 men and 48 women with an average age of 45 +/- 14 years. Most patients had inguinal hernia repairs or Pfannenstiel incisions. Mesh was found in 27% of patients. Symptoms included pain (100%), radiation of pain to the thigh and/or genital area (59%), and postural pain (59%). Diagnosis was made by physical examination, postural maneuvering, and inguinal nerve block. Proximal nerve resection was followed by Mersiline (Ethicon, Inc., Somerville, NJ) ligature and absolute alcohol or phenol application to prevent neuromas. RESULTS: Five percent of patients had minor complications. There was abnormal nerve histopathology in 18%. Total pain relief was attained in 72% of patients, partial relief in 25%, and no relief in 3%. Two patients complained of numbness postoperatively. Multifactorial analysis showed recurrent hernia repair as a significant predictive factor.     

Peritoneography (Herniography) for Detecting Occult Inguinal Hernia in Patients with Inguinodynia

OBJECTIVE: To evaluate the usefulness of peritoneography in patients referred with inguinal pain (inguinodynia) and clinically absent inguinal hernia on physical examination. SUMMARY BACKGROUND DATA: In patients with chronic groin pain, peritoneography is a seldom-used yet available technique that can detect an occult inguinal hernia. The value of peritoneography in the diagnosis of occult inguinal hernia has been previously shown. METHODS: During a 60-month period, 80 consecutive patients with complaints of persistent inguinal pain (inguinodynia) without evidence of hernia on clinical examination were referred for outpatient evaluation by peritoneography. Twenty-nine patients had prior inguinal surgery in the region of their current pain. Peritoneography was performed using a midline or paraumbilical approach. Radiographs were obtained with patients in prone and prone oblique positions with the head elevated 20 degrees to 25 degrees, both with and without provocative maneuvers. All available records were retrospectively reviewed for radiographic findings and outcome. RESULTS: Of the 80 patients undergoing peritoneography, 36 (45%) were diagnosed radiographically to have inguinal hernias that were not detectable clinically. Twenty-seven of these patients subsequently underwent inguinal exploration, and a hernia was confirmed in 24 (89%). Of the patients having prior inguinal surgery in the region of their pain, 12/29 (41%) were diagnosed by peritoneography with a hernia. Two complications (2.5%), both colon perforations that did not require significant intervention, occurred as a result of peritoneography. CONCLUSIONS: Peritoneography is highly reliable for detecting clinically occult inguinal hernia and has a low complication rate. Its usefulness is shown in a prospective consecutive series for detection of occult hernias in patients with chronic inguinal pain. The authors conclude that peritoneography is a safe and useful diagnostic test in the setting of persistent inguinal pain and a negative clinical examination.     

Decision making for a painful hip: a case requiring referral

STUDY DESIGN: Resident's case problem. BACKGROUND: The purpose of this resident's case problem is to describe a 39-year-old female patient with insidious onset of hip pain. This patient had discrete findings on subjective physical examination that prompted referral for further imaging studies of the left hip and pelvis. Despite having seen multiple providers, no imaging of the involved hip or pelvis had been performed. A prolonged duration of symptoms, severe gait disturbance with an associted Trendelenburg sign, difficulty sleeping, and an empty end feel with passive range of motion increased concern that a pathological process might be present. DIAGNOSIS: Imaging studies revealed a large destructive soft-tissue tumor later found to be non-Hodgkin's lymphoma. DISCUSSION: It is incumbent upon physical therapists to be aware of the potential for severe pathological conditions that mimic musculoskeletal complaints to exist and understand how to identify patients for whom further testing and/or referral may be appropriate. Existing guidelines for low back pain may assist with decision making in the absence of specific guidelines for when to request imaging in patients with nontraumatic hip and pelvis pain. Proficiency in screening for conditions not amenable to physical therapy treatment or that require consultation to other health care professionals is essential to physical therapy practice.     

Laparoscopic surgery for chronic groin pain in the general population: a prospective study

BACKGROUND: Chronic groin pain is a challenging problem among not only athletes but also the general population. The aim of this study was to evaluate the role of laparoscopic surgery in the management of these patients. PATIENTS AND METHODS: Prospective data including the outcomes were collected and analyzed for 43 patients who had groin pain without clinical or radiologic evidence of hernia. All patients had magnetic resonance imaging scan and had consulted an orthopedic surgeon when appropriate. All patients were followed in clinic 2 weeks after operation and 6 months after the operation by phone call, and all were asked to call our unit in case of partial or no improvement. RESULTS: From September 1999 to August 2006, we performed 1617 laparoscopic groin hernia repairs in 1209 patients using the transabdominal preperitoneal approach. Forty-three patients (3 women and 40 men) with variable life activities and employment were included in this study. Only five patients played football at a professional level. The mean age of these patients was 38 years (range, 17-74 years), and the mean follow-up was 43 months (range, 14-72 months).The clinical invagination test showed wide external inguinal ring in 27 (62.7%) patients and tender inguinal canal in another 6 (13.95%) patients. Negative laparoscopy was reported in 7 (16.27%) patients. All patients had mesh insertion. The operation cured groin pain in 30 (69.76%) patients, and the pain improved in another 9 (20.93%) patients. Three (6.97%) patients had no change in their symptoms, and the pain became worse in 1 (2.32%) patient. CONCLUSION: We suggest offering laparoscopic groin exploration and mesh insertion for any adult patient presenting with chronic groin pain without clinical evidence of groin hernia or radiologic abnormality regardless of age, life activities, and employment.     

Pre-vascular hernia: a rare cause of chronic obscure groin pain after inguinal hernia repair

A rare case of pre-vascular hernia is reported in a woman complaining of chronic obscure groin pain following an inguinal hernia repair. The condition was only diagnosed by means of a herniogram, emphasising the value of this investigation in unexplained groin pain. The hernia was successfully repaired using a polypropylene mesh plug, a simple technique widely employed in both femoral and recurrent inguinal hernia, but never before described in pre-vascular hernia.     

Successful endoscopic treatment of chronic groin pain in athletes

Background Chronic groin pain, especially in professional sportsmen, is a difficult clinical problem. Methods From January 1999 to August 2005, 55 professional and semiprofessional sportsmen (53 males; mean age, 25 ± 4.5 years; range, 17–36 years) with undiagnosed chronic groin pain were followed prospectively. All the patients underwent an endoscopic total extraperitoneal (TEP) mesh placement. Results Incipient hernia was diagnosed in the study athletes: 15 on the right side (27%), 12 on the left side (22%), and 9 bilaterally (16%). In 20 patients (36%), an inguinal hernia was found: 3 direct inguinal hernias (5%) and 17 indirect hernias (31%). All the athletes returned to their normal sports level within 3 months after the operation. Conclusions A TEP repair must be proposed to patients with prolonged groin pain unresponsive to conservative treatment. If no clear pathology is identified, reinforcement of the wall using a mesh offers good clinical results for athletes with idiopathic groin pain.     

Inguinal hernia in urological patients: the value of herniography

The value of herniography was reviewed in 45 patients with a variety of urological symptoms (4 with flank pain, 20 with pain from the funicle or scrotum, 11 with symptoms simulating prostatitis and 10 with ill-defined symptoms from the small pelvis). In no patient was a groin hernia palpable at physical examination. However, herniography revealed an inguinal hernia in 6 patients who underwent herniorrhaphy, whereafter 5 became asymptomatic. We recommend herniography in patients with long-standing obscure groin pain to reveal the presence of a nonpalpable inguinal hernia.     

Recurrence and pain three years after groin hernia repair. Validation of postal questionnaire and selective physical examination as a method of follow-up.

OBJECTIVES: To evaluate recurrence rate and chronic groin pain three years after hernia repair and to validate a postal questionnaire with selective physical examination as a method of follow-up. DESIGN: Prospective cohort study. SETTING: County hospital, Sweden. PATIENTS: Prospective data were retrieved from the Swedish Hernia Register for patients aged 15-80 years at the time of groin hernia repair, operated on during 1994. INTERVENTIONS: Three years after operation patients were mailed a three-item questionnaire and invited to have a physical examination. Those examined answered a detailed questionnaire about pain and functional impairment. When appropriate an extended physical examination was undertaken to find out the probable cause of the pain. MAIN OUTCOME MEASURES: Recurrence, pain, and functional impairment. RESULTS: 272 hernias were repaired in 264 patients. 24 patients had died and 16 had a recurrence before the follow-up examination. After a median observation time of 44 months, 218 patients with 223 repairs (96%) were examined. Depending on the definition of recurrence and completeness of physical examination (selective or all patients) the recurrence rate varied between 10% (25/239) and 15% (35/239) including recurrences diagnosed before follow-up. 40 patients (18%) reported groin pain at follow-up, which was considered to be caused by a previous hernia repair in 34 (15%), 12 of whom (5%) had moderate or severe pain. Postoperative complications were associated with an increased risk of chronic pain, whereas type of hernia and use of mesh had no influence. CONCLUSIONS: The incidence of recurrence and chronic pain after hernia repair requires continuous audit in non-specialised units. Participation in a register and follow-up by a three-item questionnaire and selective physical examination provides a solid basis for quality control.     

Carcinoma of the sigmoid presenting as a right inguinal hernia

We present the case of a 44-year-old man who presented with nausea, vomiting and acute pain in the right groin. On physical examination an irreducible mass was palpated in the right inguinal region. Ultrasound suggested an inguinal hernia sac with bowel contents. Subsequent right inguinal exploration revealed only unspecified necrotizing tissue, but no hernia sac or bowel contents were identified. Two days later laparotomy was required since the inguinal wound produced faecal discharge. The sigmoid appeared to be necrotic and perforated, and was subsequently resected. Histology revealed a perforated adenocarcinoma without lymph node involvement. Incarcerated inguinal hernias containing an adenocarcinoma of the colon are rare, but should be considered in patients presenting with an irreducible palpable mass in the inguinal region. Moreover, a carcinoma of the sigmoid may invade the right inguinal region. An intestinal perforation to skin-level in this population is even rarer and is associated with high morbidity and mortality rates.     

Minimal Repair technique of sportsmen’s groin: an innovative open-suture repair to treat chronic inguinal pain

Background  

Sportsmen’s groin, also known as sportsman’s hernia, sports hernia, (athletic) pubalgia or athletic hernia, especially in professional sportsmen, is a difficult clinical problem, and may place an athlete’s career at risk. It presents with acute or chronic inguinal pain exacerbated with physical activity. So far, the diagnostic criteria and treatment modalities are inconsistently described and there is no evidence-based consensus available to guide decision-making.     

Combined open and laparoscopic approach to chronic pain following open inguinal hernia repair

Introduction: Chronic groin pain is the most common long-term complication after open inguinal hernia repair. Traditional surgical management of the associated neuralgia consists of injection therapy followed by groin exploration, mesh removal, and nerve transection. The resultant hernia defect may be difficult to repair from an anterior approach. We evaluate the outcomes of a combined laparoscopic and open approach for the treatment of chronic groin pain following open inguinal herniorrhaphy. Methods: All patients who underwent groin exploration for chronic neuralgia after a prior open inguinal hernia repair were prospectively analyzed. Patient demographics, type of prior hernia repair, and prior nonoperative therapies were recorded. The operation consisted of a standard three trocar laparoscopic transabdominal preperitoneal hernia repair, followed by groin exploration, mesh removal, and nerve transection. Outcome measures included recurrent groin pain, numbness, hernia recurrence, and complications. Results: Twelve patients (11 male and 1 female) with a mean age of 41 years (range 29–51) underwent combined laparoscopic and open treatment for chronic groin pain. Ten patients complained of unilateral neuralgia, one patient had bilateral complaints, and one patient complained of orchalgia. All patients failed at least two attempted percutaneous nerve blocks. Prior repairs included Lichtenstein (n=9), McVay (n=1), plug and patch (n=1), and Shouldice (n=1). There were no intraoperative complications or wound infections. With a minimum of 6 weeks follow up, all patients were significantly improved. One patient complained of intermittent minor discomfort that required no further therapy. Two patients had persistent numbness in the ilioinguinal nerve distribution but remained satisfied with the procedure. Conclusions: A combined laparoscopic and open approach for postherniorrhaphy groin pain results in good to excellent patient satisfaction with no perioperative morbidity. It may be the preferred technique for the definitive management of chronic neuralgia after prior open hernia repair.     

Small bowel perforation due to blunt trauma to an inguinal hernia: a case report and literature review

We report the case of a 41-year-old man with a known right inguinal hernia presenting with groin pain following a fall while dog walking. Operative findings showed a small bowel perforation affecting the loop of bowel in the hernial sac. Bowel perforations caused by blunt abdominal injury in patients with an inguinal hernia is a rare and not well recognised problem, and are confined to a handful of case reports in the surgical literature.     

Risk of femoral hernia after inguinal herniorrhaphy

BACKGROUND: Small case series have suggested an increased risk of femoral hernia after previous inguinal herniorrhaphy, but no large-scale data with complete follow-up are available. METHODS: Data were extracted from the Danish Hernia Database covering the interval from 1 January 1998 to 1 July 2001, and included 34 849 groin hernia repairs. RESULTS: Of 1297 femoral hernia repairs, 71 patients had previously had an operation for inguinal hernia within the observation period. These 71 femoral hernias represented 7.9 per cent of all reoperations for groin hernia recorded in the database. The median time to reoperation for a 'recurrent' femoral hernia after previous inguinal herniorrhaphy was 7 months, compared with 10 months for inguinal recurrences. The risk of developing a 'recurrent' femoral hernia after previous inguinal herniorrhaphy was 15 times higher than the rate of femoral hernia repair in the general population. CONCLUSION: This study of 34 849 groin hernia repairs demonstrated a 15-fold greater incidence of femoral hernia after inguinal herniorrhaphy compared with the spontaneous incidence. These femoral recurrences occurred earlier than inguinal recurrences, suggesting that they were possibly femoral hernias overlooked at the primary operation.
