Pubic tubercle | Adductor tendon enthesopathy | Insidious onset, warms up with exercise | Guarding on passive abduction,9 weakness.10 Pubic “clock”: 6–8 | Magnetic resonance imaging11 |
Rectus abdominis enthesopathy | Well localised to insertion, acute or insidious onset | Pain from resisted sit-up.10 Pubic “clock”: 12 | Magnetic resonance imaging11 |

Diagnosis of exclusion |
Degenerative pubic symphysis | Central pain, associated with stress through symphysis—stair climbing | Tender over symphysis. Pubic “clock”: 3 | Plain film, stress view,15 magnetic resonance imaging14 |
Incipient hernia; conjoint tendon tear | Insidious onset, diminished performance, warms up | Pain on resisted “torsion” of trunk “ipsilateral direction”.16 Pubic “clock”: 11 | Ultrasound17 |
Incipient hernia; external oblique aponeurosis tear | Acute onset, related to sport-specific movement eg, “slap shot”.22 | Pain on resisted “torsion” of trunk “contralateral direction”.16 | Magnetic resosnance imaging18 |
