Caudal regression sequence: vascular origin?

Caudal regression sequence (CRS) is a rare congenital defect of the lower spinal segments and the neural tube. Motor symptoms as well as neurological deficits and loss of bladder and bowel function are usually present. CRS is also associated with anomalies in other systems such as the gastrointestinal and genitourinary tract.

Arthroscopic treatment of an avulsion fracture of the ligamentum teres of the hip in an 18-year-old horse rider.

We present the case of an 18-year-old horse rider with an avulsion fracture of the ligamentum teres causing persistent hip pain and locking for 2 years. The patient had no history of major trauma; however, repeated minor hyperabduction injuries occurred. We were able to successfully treat this patient by arthroscopic removal of the bony fragments and two loose bodies and partial resection of the ligamentum teres.
