Hemivertebra Resection in Small Children. A Literature Review.

STUDY DESIGN: Systematic review. OBJECTIVE: To evaluate the lowest possible age to resect an HV in very young patients with a congenital deformity. METHODS: We sought to retrieve all studies reporting age at HV excision in patients with congenital scoliosis. Studies written in English were included. No publication date restrictions were imposed. A search of the PubMed and LiLacs databases was conducted. Additionally, a hand search was performed to supplement the database search. RESULTS: We found 140 articles. Twenty two studies were included into the final assessment. There was considerable heterogeneity in the included studies, both regarding age and the surgical techniques used. There was also a broad spectrum of recommendations regarding suggested age for treatment. The youngest patient undergoing resection and fusion was 3 months of life at the time of surgery. CONCLUSION: How young a patient could and should be submitted to HV resection surgery is still a matter of debate in the literature. Prophylactic surgery might be a proper treatment for young children with congenital scoliosis before malformation becomes a deformity, adding no additional neurological, vascular, or anesthesia-related complications. The defect can be treated early while the deformity is treated late.

Evaluation of outpatient halo-gravity traction in patients with severe scoliosis: development of a monitoring device.

INTRODUCTION: Patients with severe spinal deformities represent a major clinical and surgical challenge. Halo-gravity traction (HGT) is a traditional method to correct the deformity prior to surgery. Typically, children undergoing HGT remain in the hospital until surgery. Therefore, it has been suggested to treat these children at lower level healthcare centers or even at home. The aim of this study was to develop a tool to assess patient adherence to HGT together with a program to analyze traction results. MATERIALS AND METHODS: An original recording system was designed with an Arduino Nano®. The data extracted from the memory card were compiled into a text file and then analyzed with the MatLab R2018a MathWorks®. RESULTS: Five patients receiving HGT for severe scoliosis were asked to use the device both in the wheelchair and in bed to evaluate its usefulness. CONCLUSIONS: A device was developed to monitor the use of HGT at home. The device provides information on the time of HGT use and the traction weight placed throughout the day, as well as on the correct functioning of the system in bed and in the wheelchair.
