# Skull-femoral traction followed by osteotomy correction is a safe and effective treatment for severe scoliosis with split cord malformation

## TL;DR

A treatment combining skull-femoral traction and osteotomy is safe and effective for severe scoliosis with split cord malformation.

## Contribution

Demonstrates a novel treatment approach for severe scoliosis with split cord malformation using skull-femoral traction followed by osteotomy.

## Key findings

- Significant improvements in coronal and sagittal Cobb’s angles were observed after treatment.
- Physiological indicators like VC, FVC, and FEV1 normalized post-treatment.
- No neurological or device-related complications occurred during or after treatment.

## Abstract

This study aimed to evaluate the safety and efficacy of skull-femoral traction followed by osteotomy correction in patients with severe spinal scoliosis and split cord malformation.

We retrospectively analyzed ten cases of severe spinal scoliosis with Pang I type split cord malformation treated between August 2012 and August 2023. Patients underwent skull-femoral traction prior to osteotomy correction. We assessed changes in height, weight, coronal and sagittal Cobb’s angles, and physiological indicators such as vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and blood gas levels before, during, and after treatment.

Traction duration ranged from 9 to 19 days, with height and weight showing significant increases post-treatment. The coronal Cobb’s angle improved from pre-treatment to post-corrective surgery and remained stable at the final follow-up. Similar improvements were observed in the sagittal plane. Physiological indicators such as VC, FVC, and FEV1, as well as blood gas levels, normalized after treatment. Nutritional status, indicated by triceps skinfold thickness, albumin, and transferrin concentrations, also improved. No neurological complications or device-related complications occurred during or after treatment.

Skull-femoral traction followed by osteotomy correction is a safe and effective treatment for severe spinal scoliosis with split cord malformation, offering an alternative to high-risk procedures.
