Conjoined Twins Have Recovered From Scoliosis Surgery
After separation in 2015, these Dallas sisters recently underwent successful spinal corrective procedures.
Updated on Oct. 2, 2026 in Special Needs
Knatalye and Addy Mata, who were born conjoined at the chest and abdomen, have successfully recovered from surgeries to correct severe spinal curvatures. The sisters underwent the procedures at Scottish Rite for Children in Dallas after living for 11 years following their initial separation.
Why it matters
Scoliosis can be a significant health complication for patients with complex medical histories, as spinal curvature may press against ribs and restrict vital lung capacity. Addressing these spinal issues is a critical component of long-term care for survivors of conjoined twin separation.
The sisters underwent a 26-hour separation surgery at 10 months old in 2015, followed by recent scoliosis surgeries that required a three-month recovery period. This recovery marks a significant milestone in their ongoing orthopedic health management.
The players
Knatalye Mata
A former conjoined twin who underwent separation surgery and subsequent spinal correction.
Addy Mata
A former conjoined twin who required surgery to correct spinal curvature that restricted her lung capacity.
Scottish Rite for Children
A Dallas-based pediatric orthopedic hospital that managed the twins' recent scoliosis surgeries.
Texas Children's Hospital
The medical facility where the twins underwent their initial separation surgery in 2015.
The details
The girls required specialized surgical intervention to correct severe spinal curvatures that developed over time. In Addy's case, the spinal condition was particularly complex, as the curvature pressed against her ribs and limited her lung capacity. Surgeons addressed these structural issues to improve the sisters' respiratory function and mobility.
Timeline
February 2015: The twins underwent their initial 26-hour separation surgery.
October 2026: The hospital announced the successful outcomes of the recent scoliosis surgeries.
Health Landscape
This case highlights the evolving standard of care for survivors of complex conjoined separation, which often includes secondary orthopedic interventions. It follows the long-term clinical trajectory set by the 2015 separation of the Mata twins.
Patients with complex early-life surgeries should remain vigilant about secondary conditions like scoliosis as they grow. Discussing potential long-term skeletal or respiratory monitoring with your doctor is a proactive step for those with similar medical histories.
The takeaway
Ongoing orthopedic and respiratory monitoring remains a critical priority for patients who have survived complex neonatal surgeries. Tracking physical changes and discussing long-term symptom patterns with a specialist can help manage potential complications as they arise.
