What are the causes of Spinal Muscle Atrophy?

Essure implants arrived on the market in 2002 as permanent contraception for women older than age 45 years with children. They were recalled in 2017. Presented as an alternative to laparoscopic tubal ligation, this medical device resulted in rare side effects affecting thousands of women, most notably the nervous system, cardiovascular system, endocrine system, and musculoskeletal system. Can someone share more details ?
