Final answer:
Developmental hip dysplasia is a condition that affects the hip joint and can cause instability and improper development. It is diagnosed through a physical examination and ultrasound. Treatment options include a harness or surgery.
Step-by-step explanation:
Developmental hip dysplasia is a condition that affects the hip joint and occurs when the hip socket is shallow or misaligned. It can cause the hip joint to be unstable and may lead to dislocation or improper development of the joint. Diagnosis of this condition typically involves a physical examination, including the 'clunk' test, and an ultrasound of the hip if necessary. Treatment options may include the use of a Pavlik harness or surgery.
There are several risk factors associated with developmental hip dysplasia, including being the first-born child, having a family history of the condition, and being in a breech position during pregnancy.
