Anterior Pain
Anterior hip pain (see Table 2) is the most commonly experienced hip pain and usually indicates pathology of the hip joint (i.e. degenerative arthritis), hip flexor muscle strains or tendonitis, and iliopsoas bursitis. In a study by Lamberts et al (1996), by far the most common diagnosis of patients with hip problems seen by their general practitioner was osteoarthritis. In a study of subjects older than 40 years who experienced a new episode of hip pain, 44% had evidence of osteoarthritis (level of evidence [LOE]=1b) (Birrell et al 2000).
The following list provides some of the causes of anterior hip pain:
-
Iliopsoas bursitis, a less common cause of anterior hip pain, involves inflammation of the bursa between the iliopsoas muscle and the iliopectineal eminence or “pelvic brim”.
-
Stress fractures typically occur in athletes as the structural demands from training exceed bone remodeling (fatigue fractures), and may also occur in the setting of osteoporosis under normal physiologic loads (insufficiency fractures).
-
Labral tears have recently been recognised in younger athletic patients with unexplained hip joint pain and normal radiographic findings (Hickman et al 2001).
