Clinical Background
Scoliosis is a common spinal deformity in adolescents and often requires surgical intervention when progressive curvature affects spinal balance, posture, or long-term quality of life. In developing regions, access to reliable spinal fixation systems and standardized surgical workflows plays a critical role in achieving predictable clinical outcomes.
In this case, a scoliosis correction procedure was successfully performed at a local orthopedic hospital in Dhaka, Bangladesh, involving a 14-year-old female patient diagnosed with adolescent scoliosis. The surgical objective was to correct spinal deformity, restore alignment, and achieve stable internal fixation using a 6.0mm pedicle screw–rod system.
Patient Profile and Preoperative Evaluation
The patient presented with clinical and radiographic findings consistent with scoliosis. Preoperative imaging examinations were conducted to evaluate the characteristics of spinal curvature and to support surgical planning. These assessments helped the surgical team determine appropriate fixation levels and correction strategy.
Given the patient’s age and deformity characteristics, achieving controlled correction while maintaining postoperative stability was a key consideration. The surgical plan focused on segmental fixation and gradual alignment correction using pedicle screw instrumentation.
Surgical Strategy and Fixation Concept
For this scoliosis correction procedure, a 6.0mm pedicle screw system was selected as the primary fixation solution. Pedicle screw–rod constructs are widely used in spinal deformity surgery due to their ability to provide strong vertebral anchorage and precise control of spinal alignment.
The system allows three-dimensional correction by addressing coronal, sagittal, and axial components of spinal deformity. Through segmental fixation across multiple vertebral levels, corrective forces can be distributed evenly, supporting spinal balance and reducing mechanical stress on individual fixation points.
Implant Specifications Used in This Case
The following implants were utilized during the procedure:
6.0 Polyaxial Pedicle Screw
6.0 Crosslink-I (SW3.5)

Its ergonomic design helps surgeons in Bangladesh and other regions perform complex scoliosis correction more efficiently and safely, reducing operative time and supporting accurate screw placement.
Postoperative Assessment and Outcome
Postoperative imaging demonstrated improved spinal alignment compared to preoperative status. The fixation construct appeared stable, supporting the intended correction. According to the surgical team, the patient showed satisfactory postoperative recovery, with no immediate fixation-related complications reported.
