“Evie received some major gifts for her 1st birthday,” the 24-year-old TLC star captioned a picture with her baby girl from the hospital on Monday. “Her surgeon laid the groundwork for her new foot and mobility it will bring, by way of a boyd amputation.”

According to the National Library of Medicine, Boyd amputations are used to treat osteomyelitis of the foot, and provide a “more solid stump because it preserves the function of the plantar heel pad.”

Maddie also said of her daughter’s hand, “Another gave her some extra mobility in her hand, by clipping her webbing she had in her right hand. She is home and is recovering beautifully.”

In October, the reality star first shared on Instagram that Evie has FATCO syndrome, which she said was “a rare medical syndrome where bones in extremities do not fully develop.”

“It wasn’t a complete surprise; we were aware of some abnormalities before birth,” she said. “We knew something was wrong when we went in for a routine anatomy ultrasound at 26 weeks and what should have taken 45 minutes, ended up lasting a nerve-wracking two hours. It was then that the doctor told us that they couldn’t find all ten fingers and diagnosed the baby with oligodactyly (fewer than 10 fingers).”

Maddie said that after Evie’s birth, she and Caleb discovered that their newborn was missing three fingers, a toe, her fibula, had a bowed tibia, a shortened forearm and some fusing in her fingers.

“We were hesitant to share Evie’s condition publicly for fear that our infant daughter would become the target of mean jokes and cyberbullying,” she wrote. “That said, we felt not being open would be even worse and make Evie feel ashamed for something that makes her all the more special in our eyes.”

Caleb and Maddie also share a 3-year-old son, Axel James.
