- Title
- Comparison of effectiveness between cobalt chromium rods and titanium rods for treatment of patients with spinal deformity. Systemic review and Meta-analysis
- Review Question
- What is the best rod material to enhance the correction of spinal deformity for patients undergoing posterior instrumentation?
- Study Type Included
- No restrictions on the types of study
- Condition Being Studied
- Advanced spinal instrumentation have enabled greater correction of spinal deformities and increased fusion rate though the selection of rods with respective to their mechanical properties still in further studies. Rod material has significant implications on its durability, biocompatibility and artifact production during advance imaging and should be considered carefully. The rates of rod fractures increases with the decreasing fatigue strength of the material being used. Therefore, biomechanical differences in fatigue failure seen in cobalt chromium and titanium rods in posterior spinal fusion has to be well investigated.
- Participant
- Inclusion criteria (1) Studies comparing the effectiveness of cobalt chromium rods and titanium rods (2) Studies elucidating posterior instrumentation with cobalt chromium or titanium rods for correction of spinal deformity (3)Studies published in English with no restriction (4) No geographic or surgical technique restriction was set. Exclusion criteria (1) Studies based on animal experiment and cadaveric research (2) Studies with another surgical technique (3) Studies published in another language other than English (4) Studies comparing other rods constructs.

- Main Outcome
- 1.Correction rate (main curve); Postoperative correction%= ((preoperative full-standing Cobb angle-postoperative full-standing Cobb angle)/ postoperative full-standing Cobb angle) 2. Thoracic kyphosis; Is an abnormally excessive convex curvature of the thoracic spine; measured by a software in a computer preoperative, postoperative and at last follow-up. 3. Lumbar lordosis; Is an increased inward curving of the lumbar spine; measured by a software in a computer preoperative, postoperative and at last follow-up. 4. Rod fracture; Is the most frequent mode of implant failure in long-segment spinal fusion surgery; Noted in postoperative radiography. 5. Fatigue life of rods; the fatigue life of rods measured in number of cycles at maximum compressive loading levels. 6. Proximal junction kyphosis (PJK); Is a postoperative radiographic phenomenon observed in the sagittal plane following instrumentation and fusion for spinal deformity. Measures of effect None
