Groin pain in athletes
• J Am Acad Orthop Surg. 2007 Aug;15(8):507-14
• Sports hernia
• Imbalance in trunk stabilizers and adductor muscles
• Soccer, hockey, hurdling, running
Groin pain in athletes
• Activity related
• Normal X-rays
• All investigations negative
• Long conservative treatment
• Hernia repair
• Longterm absence on the field
Groin pain in athletes
Extra-articularCause for pain
Intra-articularCause for pain
Intra-articular causes for groin pain
• Acute injury
– Torn ligamentum teres– Loose body, cartilage lesion
• Gradual onset
– Concept of impingement

Concept of femoro-acetabular impingement
FAIdynamic concept
Developed by R. Ganz (Bern)
1. cam - impingement
2. pincer - impingement

cam - impingement
Consequences
labral tears
wave sign
delaminated cartilage
early arthritis
– Osseous bump• “variant”• Idiopathic• old LCP• subclinical slipping
– Femoral retroversion
– Coxa vara
cam - impingement
– Bone Marrow Edema
– Labral tear
– Cartilage lesions
– Subchondral cyst formation
– (Bump-cyst complex; herniation pit)
– Os acetabuli
cam - impingement
CAM FAI: intact labrum + wave sign

FAI
pincer - impingement
Pincer FAIPincer FAI
– Acetabular origin
– Acetabular overcoverage
– Coxa profunda
– Protrusio acetabuli
pincer - impingement
Consequences
Abutment nek tegen anterior wall
Mainly labral tears
Contre-coup lesions
Often combined impingement
Clinical features of FAI
• Click, locking of the hip• Limited internal rotation• Pain in ADduction, Flexion and internal rotation• Gondolière sign +• McCarthy +• C-sign +• Pain during sport, may aggrevate afterwards
• Testen– Faber
Clinical features of FAI
• Testen– Mc Carthy
Clinical features of FAI
Radiological findings of FAI
• Standard X-ray
• Arthro MRI
• 3D CT-scan
• In doubt : Injection of the joint
Standard X-Rays
- Comparison of contralateral Comparison of contralateral hiphip
- Leg lengthLeg length
- Pelvic rotationPelvic rotation
- Pelvic tiltPelvic tilt
- Correct evaluation Correct evaluation acetabular retroversionacetabular retroversion
- Coccyx must be centered over the pubic symphysis and should be not separated more than 2 cm
Standard radiography: standing AP pelvis
Standard X-rays

Value of correct positioningValue of correct positioning
• Standard radiography: 3/4
– Lateral neck
Standard X-rays
• Other valuable radiographs– Lequesne (faux
profile)• Profile of acetabulum:
anteversion, retroversion
– Dunn view• 90° flexion/ abduction
20°• Anterior femoral neck
