The condition is most commonly found in children between the ages of 4 and 10. Common symptoms include pain in the hip, knee, or ankle (since hip pathology can cause pain to be felt in a normal knee or ankle), or in the groin; this pain is exacerbated by hip or leg movement, especially internal hip rotation (with the knee flexed 90°, twisting the lower leg away from the center of the body).
Kaltenborn test or Hip Lag Sign for hip abductor function. To perform the Kaltenborn test, the patient has to lie in a lateral, neutral position with the affected leg being on top. The examiner then positions one arm under this leg to have good hold and control over the relaxed extremity, whereas the other hand stabilizes the pelvis.
In both tests, the patient is placed in a standing or sitting position, and the arms are raised parallel to the ground in the scapular plane. [2] The tests differ in the rotation of the arm; in the empty can test, the arm is rotated to full internal rotation (thumb down) and in the full can test, the arm is rotated to 45° external rotation, thumb up.

On clinical examination, the child typically holds the hip slightly bent, turned outwards and away from the middle line (flexion, external rotation and abduction). [7] Active and passive movements may be limited because of pain, especially abduction and internal rotation. The hip can be tender to palpation. The log roll test involves gently ...
In addition, an internal rotation of the respective hip joint is either not possible or accompanied by pain when forcefully induced. [ 2 ] The positive Drehmann sign is a typical clinical feature in slipped capital femoral epiphysis (SCFE), the impingement syndrome of the acetabulum-hip , or in osteoarthritis of the hip joint.
The examiner internally rotates the hip by moving the patient's ankle away from the patient's body while allowing the knee to move only inward. This is flexion and internal rotation of the hip. In the clinical context, it is performed when acute appendicitis is suspected. In this condition, the appendix becomes inflamed and enlarged.
It has also been suggested that symptoms are caused by impingement of the iliotibial band in the knee during 30 degree flexion, which is a position common in running and cycling. [11] Additional proposed mechanisms causing the symptoms of ITBS include compression of the fat and soft tissues beneath the iliotibial band, and chronic iliotibial ...
Symptoms include the gradual, progressive onset of thigh or knee pain with a painful limp. Hip motion will be limited, particularly internal rotation. Running, and other strenuous activity on legs, will also cause the hips to abnormally move due to the condition and can potentially worsen the pain. Stretching is very limited.
