PURPOSE: The purpose of this retrospective research is to judge the efficacy and security of posterior-only vertebral column resection (PVCR) for the remedy of angular and remoted congenital kyphosis.
METHODS: 24 sufferers with remoted angular congenital kyphosis handled by PVCR in our hospital have been retrospectively studied. The sufferers’ radiographs and hospital data have been reviewed. Deformity in sagittal planes and international sagittal alignment have been analyzed for correction and upkeep of the correction in preoperative, postoperative, and follow-up radiographs. The issues and associated danger elements have been analyzed.
RESULTS: The typical age was 13.9 (Four-40) years. Three of them have been revision surgical procedures. Two sufferers have intraspinal anomalies. The imply follow-up is 56.9 (26-129) months. The imply operation time was 293.1 (170-480) min. The averaged blood loss was 993.eight (250-3000) ml. The segmental kyphosis was 87.three° earlier than surgical procedure, 17.6° submit surgical procedure and 20.Four° on the newest the follow-up. And the sagittal vertical axis was improved from 43.1 mm to 9.2 mm. Imply complete rating of SRS-22 was 89.three. Issues occurred in Four sufferers, together with 1 screw pullout as a consequence of pseudarthrosis, 1 proximal junctional kyphosis, 1 incomplete spinal twine damage and 1 root accidents.
CONCLUSION: Posterior-only vertebral column resection is a perfect process for extreme inflexible congenital kyphosis. Nonetheless, it’s nonetheless a extremely technical demanding process. Neurological compromises nonetheless stay the largest challenges. Enough peak of anterior reconstruction, avoidance sacrifice of bilateral roots in the identical degree within the thoracic backbone, avoidance of the sagittal translation of the higher and decrease vertebras, intra-operative neuromonitoring, and preoperative surgical launch of diastematomyelia and tethered twine could assist to enhance the security.
