Pubalgia 1
Pubalgia 1
     ABSTRACT
     Background: Evaluation and treatment of groin pain in athletes is challenging. The anatomy is complex, and
     multiple pathologies often coexist. Different pathologies may cause similar symptoms, and many systems
     can refer pain to the groin. Many athletes with groin pain have tried prolonged rest and various treatment
     regimens, and received differing opinions as to the cause of their pain. The rehabilitation specialist is often
     given a non-specific referral of “groin pain” or “sports hernia.” The cause of pain could be as simple as the
     effects of an adductor strain, or as complex as athletic pubalgia or inguinal disruption. The term “sports her-
     nia” is starting to be replaced with more specific terms that better describe the injury. Inguinal disruption is
     used to describe the syndromes related to the injury of the inguinal canal soft tissue environs ultimately
     causing the pain syndrome. The term athletic pubalgia is used to describe the disruption and/or separation
     of the more medial common aponeurosis from the pubis, usually with some degree of adductor tendon
     pathology.
     Treatment: Both non-operative and post-operative treatment options share the goal of returning the ath-
     lete back to pain free activity. There is little research available to reference for rehabilitation guidelines and
     creation of a plan of care. Although each surgeon has their own specific set of post-operative guidelines,
     some common concepts are consistent among most surgeons. Effective rehabilitation of the high level
     athlete to pain free return to play requires addressing the differences in the biomechanics of the dysfunc-
     tion when comparing athletic pubalgia and inguinal disruption.
     Conclusion: Proper evaluation and diagnostic skills for identifying and specifying the difference between
     athletic pubalgia and inguinal disruption allows for an excellent and efficient rehabilitative plan of care.
     Progression through the rehabilitative stages whether non-operative or post-operative allows for a focused
     rehabilitative program. As more information is obtained through MRI imaging and the diagnosis and treat-
     ment of inguinal disruption and athletic pubalgia becomes increasingly frequent, more research is war-
     ranted in this field to better improve the evidence based practice and rehabilitation of patients.
