Conjoined twins are identical twins joined in utero and are a rare phenomenon. This report discusses a case of female thoraco-omphalo-ischiopagus tripus conjoined twins. The twins were separated at age two, and once medically stable, spent one month in inpatient rehabilitation to improve their sitting balance and gross motor skills. This was followed by outpatient physical therapy. The twins initially had customized ZipZac seats, which they were able to wheel independently. After six months of therapy, the girls began walking with posterior walkers and prostheses. The hemipelvectomy prosthesis included a customized thoracolumbosacral orthosis component and was directly attached to a non-articulated pylon. A manual-locking hip joint was added to accommodate sitting. An articulated ankle-foot orthosis was used for the intact leg. Care of formerly conjoined twins requires comprehensive care from a multidisciplinary team involving, but not limited to, a physiatrist, orthopaedic surgeon, physical therapist, and orthotist/prosthetist. Complex congenital limb deficiencies are often a major undertaking for the rehabilitation team as continuous treatment and management are needed throughout the patient's lifetime due to growth, development, and evolving physical demands. Anatomic variations must be examined on a case-by-case basis but often include limb deficiencies, orthopedic abnormalities, and organ comorbidities.
