A 10-year-old female with neurofibromatosis type 1 and severe dysplastic scoliosis, presented with a two-month history of difficulty ambulating due to lower back pain. The patient did not have neurological symptoms. An MRI of the thoracolumbar spine demonstrated subluxation of the right tenth and eleventh ribs through the neural foramina, causing mass effect on the thecal sac, but at T9-T10 without abnormal cord signal or cord compression. Several clusters of neurofibromas were present along the right ribs and paravertebral soft tissues at these levels. CT evaluation was performed for greater osseous definition, which confirmed the findings. The patient underwent complex posterior spine fusion and segmental spinal instrumentation, which included T9-T10 thoracoplasty, rib resections, and multiple Ponte osteotomies.
Cases of rib head protrusion into the central canal in the setting of dystrophic scoliosis have been documented in only a limited sample of case reports. The angulated short-segment curvature in dystrophic scoliosis causes vertebral body rotation, foraminal enlargement, spindling of transverse process, and penciling of the apical ribs. These changes can alter the articulation of the rib along the spinous process. The enlarged foramina also create a space into which a rib may displace. As a result, in most reported cases, the subluxed ribs were on the convex apex of the curve in the mid-to-lower thoracic region. The risk of cord injury makes complete depiction of the anatomy crucial for surgical management. Read More

X-Ray based manual Cobb angle measurement is inherently time-consuming and associated with high inter- and intra-observer variability. The existing automated scoliosis measurement methods suffer from insufficient accuracy. We propose a two-step segmentation-based deep architecture to automate Cobb angle measurement for scoliosis assessment. Read More

Scoliosis is a deformity of the spine that affects 2-3% of the population. Currently, the reference standard for assessing scoliosis is the manual assignment of Cobb angles at the site of the curvature center using X-ray images. This process is time consuming and unreliable as it is affected by inter- and intra-observer variability. To overcome these inaccuracies, machine learning (ML) methods can be used to automate the Cobb angle measurement process. Read More

The purpose of this study is to outline the benefit of speed stitching and recognize it as one of the best stitching tools available for the pediatric population. Looking at the history of stitching, we started by using the CR for scoliosis and long bones stitching. The time of exposure, the radiation dose, and image quality were not optimal. Moving to automatic DR stitching was a good step in the right direction. However, there was still a frustration from having to repeat so many exams because of the high possibility of motion captured between exporsures. That’s when speed stich came to play with fast acquisation and less operator interference while doing the exam. Read More

The major concern for scoliosis in young children is the potential for poor pulmonary function and increased mortality. Early arthrodesis as well as severe spinal deformities can lead to ‘thoracic insufficiency syndrome’ by arresting spine growth and altering the shape of the thorax which results in restrictive lung disease. Several growth friendly instrumentation systems have been introduced to allow for growth until the timing is appropriate for spinal fusion for early onset scoliosis. The terminolgy of ‘growth friendly procedures ‘ is used for those which guide the growth of the spine. Growth modulation procedures are different from growth friendly procedures in the sense that vertebral growth is modulated and not guided. We aim to familiarize the radiologist by reviewing the types of ‘growing spine’ procedures performed at our hospital with an emphasis on what the radiologists should know and include in their reports.

Our hospital is a local tertiary referral centre for paediatric spinal deformities. Patients were traditionally imaged with digital radiography and secondary digital stitching of images. Repeated imaging is routinely required for monitoring of disease progression.
EOS biplanar X-ray imaging unit is a novel system utilizing slot-scanning technology to acquire high-quality full-length images of patients in an upright weight-bearing position. The EOS system is now commonly used in Western countries. However, studies describing utilization in Asian population has not been published, according to our understanding. This study aims to describe our local experience, in particular lower radiation dose requirements when compared with default settings. Read More

We will present imaging findings of segmental spinal dysgenesis in a series of 3 cases of this rare congenital abnormality. We will also describe the embryological basis and pertinent clinical features.

Case 1: 8-year-old female recently adopted from China with history of severe scoliosis, neurogenic bladder, and chronic kidney disease. Plain radiographs demonstrate severe destroscoliosis in thoracolumbar region with associated kyphosis. MRI reveals multiple segmentation/formation anomalies in the lumbosacral region. The coccyx was not identified, likely representing associated partial sacrococcygeal dysgenesis. The spinal cord was severely dysgenetic in the lower thoracic region (Figure 1, white outlined arrow). The superior segment of the spinal cord extends from the cervicomedullary junction to the level of T8, where it ends abruptly. No intervening cord tissue is seen between the T8 level and lumbar region. There is an enlarged spinal cord segment at the level of the sacrum in the spinal canal, separate from the superior segment (Figure 2, solid white arrow). CT with 3D reconstruction better demonstrated multiple segmentation/formation anomalies in the thoracic and lumbosacral region, including butterfly vertebrae, hemivertebrae, and block vertebrae. There were 10 ribs on the right noted with the superior 2 ribs fused. Read More
