History and Physical Examination
The presentation and findings of patients with osteochondrosis depend on the site of involvement and on the stage to which the syndrome has progressed.
Pain that is localized to the affected site is usually present in the initial stages (eg, pain during kneeling in patients with Osgood-Schlatter disease or referred pain to the knee in those with Perthes disease). However, clinicians should remember that patients are asymptomatic more often than not and that they typically present late, after the onset of disability. Nonspecific bone and joint pains that occur in children during growth spurts are often overlooked, and many of these may reflect osteochondroses.
Findings commonly found alone or in combination include the following:
-
Localized tenderness
-
Limited movement of adjacent joints
-
Swelling
-
Gait disturbance (when the disease affects the lower limbs)
-
Reactive effusion in an adjacent joint (sometimes observed)
Growth disturbance and secondary deformities are late presentations in specific entities, such as Blount disease (shortening and tibia vara), Scheuermann disease (kyphosis), and Perthes disease (shortening and coxa vara, magna, or brevis).
Of greatest importance is that systemic symptoms of inflammation (eg, fever, malaise, weight loss, local redness, and raised temperature) should alert physicians to search for causes other than an osteochondrosis.
-
Osteochondrosis of the lesser trochanter of the left femur (Monde-Felix disease). Image shows fragmentation.
-
Perthes disease. Anteroposterior view of the pelvis and both hips. Image shows pathology involving the right hip joint. Also depicted is flattening, fragmentation, and sequestrum formation affecting the capital epiphysis of the femur, with metaphyseal cyst formation and osteopenia. Of note, no subluxation of the hip joint is observed.
-
Osteochondrosis of the base of the fifth metatarsal bone (Iselin disease). Image shows fragmentation.
-
MRI in the same patient as in image above shows altered marrow signal intensity in the apophysis of the fifth metatarsal base. This finding is suggestive of Iselin disease.
-
Perthes disease. Lateral view of the same patient as in image above shows flattening of the epiphysis, as well as sclerosis with deformation of the femoral head.
