BackgroundA selective dorsal rhizotomy (SDR) is employed to treat spastic cerebral palsy. The surgical techniques and patient care protocols vary among hospitals. One of the variations is the age cut-off for SDR. We have been advocating SDR to be performed early - especially at ages 2 and 3. With this study, we are reporting the feasibility and parent-reported surgical outcomes of receiving SDR at an early age for the treatment of spastic diplegia.ObjectivesOur aim is to examine the safety and benefits of receiving SDR at the ages of 2 and 3 for the treatment of spastic diplegia.MethodsThe Institutional Review Board (IRB) of Washington University School of Medicine approved this retrospective quality of life survey and chart review (approval #202009056). The subjects of this study were children and teens (ages: 3.9-18.1) with spastic diplegic cerebral palsy who underwent SDR at ages 2 or 3 between years 2005 and 2019 at St. Louis Children’s Hospital. Only domestic patients that were minors at the time of the study were selected to be participants in compliance with IRB regulations to protect patient health information that could potentially be breached by sending information to an incorrect or dated email. Thus, all contact was made through postal mail. The study included 141 patients from a total of 362 eligible patients. Parents of eligible patients were sent the research survey via postal mail. Only patients who responded to the survey were included in this study. The survey included questions on demographic information, quality of life, health perception, motor and ambulatory functions, braces and orthotics, pain issues, side effects of SDR, and post-SDR treatment.ResultsThe study included 141 diplegic patients. Of all patients at the time of the study, 91% reported an improvement in walking, 92% in standing, and 89% in sitting. In daily life activities, 87% of patients became more independent after SDR. 65% of patients were able to walk without a walking aid and about 4% were not able to walk. 11% of all patients relied mostly on a wheelchair. Moreover, 43% of patients were able to run independently. Regarding post-SDR orthopedic surgery, 48% of patients received at least one type of orthopedic surgery, with Achilles tendon lengthening, hamstring lengthening, and calf muscle release being the most common types. ConclusionsSDR performed at an early age through a single-level laminectomy was proved feasible and safe. A follow-up until the adult age (18 years) showed improvements in walking and other motor functions. The results support the implementation of early-age SDR for the treatment of spastic diplegia.
