II. Definitions
- Sports Hernia (Athletic Pubalgia)
- Lower abdominal or inguinal pain, outside the ball and socket Hip Joint, in athletes
III. Background
- First described in 1980-1990s with rupture of the oblique aponeurosis and conjoined tendon
- As of 2019, there are 19 distinct syndromes of defects grouped under Sports Hernia
IV. Risk Factors
- Male gender (>85% of cases)
- Participation in kicking, cutting, sudden forceful twisting and turning (e.g. american football, ice hockey, baseball)
V. Pathophysiology
- See Pubic Joint for anatomy of Muscle complex insertions (abdominal and thigh flexors, abductors and rotators)
- Weakening of posterior Inguinal Canal wall (85% of cases)
- Results in occult, non-palpable Hernia
VI. Types
- Adductor-Related Groin Pain
- Iliopsoas-Related Groin Pain
- Pubic-Related Groin Pain
VII. Symptoms
- Characteristics
- Chronic, progressive unilateral deep Groin Pain and hip adductor pain in athlete
- Timing
- Insidious onset with gradual worsening, worse with activity and better with rest
- Radiation
- Inguinal ligament
- Thigh and Perineum
- Rectus Muscles
- Testicular Pain (30%)
- Provocative
- Increased intra-abdominal pressure (Valsalva Maneuver, coughing, sneezing, sit-ups)
- Resistance Training of abdominal Muscles
- Sprinting, kicking or cutting in sports
VIII. Signs
- See Hip Pain for full exam
- Difficult to diagnose except during surgery
- Inguinal Hernia not detectable (affects posterior wall)
- Tenderness to palpation over conjoint tendon, pubic tubercle, midinguinal
- Provocative Tests
- Also see diagnosis as below
- Direct Stress Test (with Straight Leg Raise)
- Examiner palpates Superficial Inguinal Ring, while patient lies supine
- Increased pain when patient performs Straight Leg Raise (reproduces patient's symptoms)
- Sit-ups
- Tenderness on palpation of rectus abdominis insertion on pubic ramus while patient performs sit up
- Resisted sit-up also provokes pain
- Other positive findings
- Adductor Squeeze Test
- Resisted hip adduction related pain (at 0, 45 or 90 degrees of hip flexion)
IX. Differential Diagnosis
- See Groin Injuries in Athletes
- See Hip Pain Causes
- Distal rectus strain or avulsion
- Groin Disruption (medial and inferior to Sports Hernia)
- Adductor Strain
- Femoroacetabular Impingement (FAI)
- Osteitis Pubis
- Snapping Hip
- Nerve Entrapment
- Genitofemoral nerve entrapment
- Upper anterior thigh and Groin Pain
- Follows abdominal surgery (also seen in cyclists)
- Ilioinguinal Nerve Entrapment
- Upper medial thigh or genital pain
- Obturator Nerve Entrapment
- Medial thigh and adductor region pain
- Genitofemoral nerve entrapment
X. Diagnosis: Requires 3 of 5 to be present
- Pubic tubercle point tenderness (conjoint tendon insertion)
- Deep Inguinal Ring point tenderness
- Superficial Inguinal Ring tenderness or dilation without obvious Hernia (scrotal inversion with finger)
- Adductor longus tendon origin pain
-
Groin Pain that is dull, diffuse
- May radiate to perineum, inner thigh or across the perineum
XI. Imaging
- Imaging typically rules out other diagnoses and in some cases may identify findings suggestive of Sports Hernia
- XRay
- Evaluates for Fractures and Stress Fractures
- Femoroacetabular Impingement (FAI) is found in 80% of surgery confirmed Athletic Pubalgia
-
Ultrasound
- In skilled hands, exam augmented by Bedside Ultrasound can be useful
- May demonstrate Tendinopathy (hypoechoic regions)
- Herniation during valsalva may be visualized in some patients
- MRI
- Common rectus abdominis - adductor longus aponeurosis Injury
XII. Management
- Conservative therapy trial for 4-8 weeks
- Relative rest from provocative activity
- NSAIDS
- Stretching and strengthening in a physical therapist directed program
- Consider Ultrasound-guided injection of Corticosteroids or plasma-rich Platelets
- Surgical exploration if conservative therapy fails
- Multiple repair strategies exist
- Successful return to sport in 90% of cases
