definition first described by Eulenberg in 1863 first described by Eulenberg in 1863 Scapula is: Scapula is: more superiorly than normal more superiorly than normal Misshapen Misshapen Hypoplastic Hypoplastic Other congenital anomalies may be present such as cervical ribs, malformations of ribs, and anomalies of the cervical vertebrae Other congenital anomalies may be present such as cervical ribs, malformations of ribs, and anomalies of the cervical vertebrae 7/7/20163sprengel deformity

The deformity develops due to arrest of the caudal migration of the scapula during development The deformity develops due to arrest of the caudal migration of the scapula during development The deformity may cause functional and cosmetic impairment of the shoulder that is related to the extent of elevation of the scapula and severity of pathological condition The deformity may cause functional and cosmetic impairment of the shoulder that is related to the extent of elevation of the scapula and severity of pathological condition Almost always sporadically Almost always sporadically 7/7/20164sprengel deformity
