Case Study: Complex Spinal Deformity Correction with Individualized Surgical Planning

Complex spinal deformities can present unique challenges, particularly when neurological compression, instability, and variations in vascular anatomy are involved. This case highlights how detailed preoperative planning can help guide an individualized surgical strategy.
Patient Presentation
An 80-year-old female patient presented with cervical compressive myelopathy associated with a reducible atlanto-axial dislocation. Flexion and extension imaging demonstrated an increase in the atlas-dens interval, indicating instability at the upper cervical spine.
Given the complexity of the condition and the proximity of the vertebral arteries to the surgical area, detailed preoperative assessment was important before instrumentation.
Preoperative Vascular Assessment
A CT angiogram revealed a hypoplastic right vertebral artery along with a dominant left vertebral artery. This anatomical variation was an important consideration while planning the C1 screw fixation.
Rather than using an identical technique on both sides, the fixation strategy was individualized according to the patient’s anatomy.
Individualized Surgical Technique
For the right C1 arch, screw placement was performed using Abumi’s technique.
On the left side, the C1 screw was inserted using Goel’s technique, which, according to the case presentation, was selected because it does not endanger the vertebral artery.
The case demonstrates an important principle in spinal deformity correction: surgical techniques may need to be adapted to the patient’s specific anatomical characteristics rather than following a uniform approach.
Cost-Conscious Implant Selection
The case also incorporated consideration of treatment affordability. A regular fully threaded screw was used on the right side, while a partially threaded shank screw was used on the left. The case presentation notes that the regular screw was selected on the right to reduce surgical cost because it was less expensive than the shank screw.
This illustrates how careful planning can potentially optimize both the surgical approach and treatment expenditure when clinically appropriate.
Key Learning Point
This case emphasizes that successful management of complex spinal deformity begins well before surgery. Detailed imaging, recognition of vascular anatomy, appropriate selection of fixation techniques, and consideration of patient-specific circumstances can all contribute to thoughtful treatment planning.
For patients seeking spinal deformity correction in Jayanagar, evaluation by an experienced spine specialist can help determine the nature of the deformity and the most appropriate treatment pathway.
Dr Yogesh K Pithwa and Sattvik Spine & Scoliosis Center in Jayanagar, Bengaluru, focus on specialist evaluation and individualized management of complex spinal conditions. The center’s academic material highlights the importance of careful preoperative planning in optimizing treatment outcomes.
