An irreducible knee dislocation: a case report.

An 8-year-old man presented after sustaining an injury during a fall. A closed reduction attempt failed, and after several tests, an open reduction was performed. With posterolateral dislocation of the knee, there can be anterior cruciate ligament, posterior cruciate ligament, and medial collateral ligament disruption. At the 6-month (final) follow-up, the patient had no subjective pain or instability. With this type of injury, the approach can be conservative monitoring or repair of all of the ligaments. Because of the age and activity level of our patient, we opted for repair of the medial collateral ligament initially with the possibility of late anterior cruciate ligament and/or posterior cruciate ligament reconstruction.

Ultrasonography in the management of developmental dysplasia of the hip (DDH).

Real time ultrasonography, according to the method of Graf, was performed on 113 infant hips because of abnormal physical findings (ranging from hip clicks to frank dislocation). Three parameters were measured on the standard coronal images: alpha and beta angles of Graf and the d/D ratio of Morin. Results indicated that the presence of hip clicks (88 hips) in general is a benign condition and not associated with abnormal anatomy. Hips that were reduced at birth but dislocatable (Barlow hip) showed no significantly abnormal acetabular anatomy. Hips that were dislocated at rest but were reducible (Ortolani hip) showed definite abnormal acetabular anatomy and femoral head coverage. Ultrasonography is beneficial in the management of developmental dysplasia of the hip (DDH); it confirms the clinical findings and eliminates radiation exposure to the infant's pelvis, especially in the first 4-6 months of life when standard radiography is not always reliable in diagnosing DDH.
