A very common injury resulting from physical activity, including sports. Most common is adductor-related, iliopsoas-related, inguinal-related, and hip-joint-related groin pain.
Most common presentation for intra-articular pathology of the hip joint; however, referred pain from other sources is not uncommon.
Signs and symptoms typically include activity-related pain, pain with movement of the hip, and antalgic gait.
The first-line diagnostic test for most conditions is a set of standard radiographs. More advanced imaging modalities, such as ultrasound and MRI, should be used with discretion when clinically indicated.
Establishing the correct diagnosis is the first step to instituting appropriate treatment. Treatment may vary widely depending on the disease entity present.
In select cases, such as stress fracture, failure to recognize and obtain timely surgical consultation can lead to significant morbidity and complications for the patient.
Groin pain is a common presenting symptom for patients of widely varying ages in the primary care setting. Common causes include trauma and overuse injuries. It can also be due to referred pain from nonmusculoskeletal sources (e.g., urogenital, gastrointestinal, neurologic). This topic focuses on exercise- and activity-related issues.
History and exam
Key diagnostic factors
- acute pain related to trauma
- history of sports-related or overuse injury
- positive anterior impingement test (FADIR test)
- pain on adduction against resistance (neutral hip flexion)
- pain on palpation of adductor tendons
- pain on palpation of iliopsoas
Other diagnostic factors
- pain on passive range-of-motion testing of the hip joint
- snapping/clicking hip
- positive Trendelenburg test
- positive apprehension test
- positive modified Thomas test
- pain on palpation of inguinal canal
- pain on palpation of conjoined tendon at pubic tubercle
- decreased strength and increased pain with hip flexion against resistance (90˚)
- night pain/rest pain
- previous groin injury
- female sex
- training background
- age and sports experience
- decreased range of motion of the hip
- muscle strength
1st investigations to order
- plain radiographs (anteroposterior [AP] pelvis and AP and lateral hip)
Investigations to consider
- ultrasound of the hip
- MRI of the hip
- MRI arthrogram of the hip
- CT of the hip
- isotope bone scan of the hip
- intra-articular injection corticosteroid ± local anesthetic agent
femoral neck stress fracture
traumatic or overuse injury: initial presentation
traumatic or overuse injury: not responding to initial management
