Sprengel's deformity (also known as high scapula, scapular hypoplasia, or congenital high scapula) is a rare congenital skeletal abnormality where a person has one shoulder blade that sits higher on the back than the other. The deformity is due to a failure in early fetal development where the shoulder fails to descend properly from the neck to its final position. Majority of the cases are sporadic with very few having autosomal dominant inheritance.[1]
The deformity is associated with the following conditions:-
The left shoulder is more commonly affected, but it can occur bilaterally as well.[1]
About 75% of all observed cases are girls. Treatment includes surgery in early childhood and physical therapy. Surgical treatment in adulthood is complicated by the risk of nerve damage when removing the omovertebral bone and when stretching the muscle tissue during relocation of the shoulder.
