Abstract
A retrospective descriptive preliminary study on early experience using all pedicle screw correction
Pedicle screw fixation enables enhanced correction of spinal deformities. However, the technique is still in early development in our clinic. Tends of the scoliosis patient to come in late ages make maximum correction failed.
A total 16 patients are subjected to pedicle screw fixation for spinal deformities were analyzed descriptively as an early follow-up in the last two-year. 14 patients are girl and 2 are boys. The age range between 12 to 18 year. 8 are Kings type II and 8 are Kings type III, 212 screws were inserted between Th3 – L2 (14-18 screws per-patient), all concave pedicles were inserted with screws but in convex side every two or three pedicles were inserted. The position of screws was analyzed using the post-operative plain X ray film.
Before surgery the mean deformity measurement are 52.56° (range, 42-72°, correction achieved was 18° (range 10-34%, it was correlated to 68% achievement (range, 53-80%). All patients are happy with their image improvement.
In total 212 screws inserted, 28 screws are malpositions (13.2%), but no clinical complication recorded.
In this early experience using all pedicle screw scoliosis surgery, all patients are happy with the results although the correction only 53-80(. More patients are needed to improve this achievement.
