We evaluated the safety and efficacy of pedicle screw fixation in the thoracic spine. \\r\\nMethods: We retrospectively reviewed 144 patients (65 males, 79 females; mean age 38 years; range 9 to 82 years) who underwent posterior thoracic pedicle screw instrumentation. A total of 827 thoracic pedicle screws were inserted to the thoracic spine (T1-12) by the same senior spine surgeon using the free-hand technique. Indications for thoracic spine surgery were deformities (n=47, 32.6%), metastatic or primary tumors (n=15, 10.4%), spinal infections (n=7, 4.9%), degenerative diseases (n=13, 9%), and spinal trauma (n=62, 43.1%). Screw containment was assessed by three independent reviewers on postoperative plain radiographs. In addition, thin-slice computed tomography scans were obtained in 21 suspected cases (29 screws). \\r\\nResults: Screw containment was found in 94.3% (780 screws). Incorrect screw placement was found in 47 screws (5.7%), including 31 screws (3.8%) demonstrated by plain radiographs, and 16 screws (1.9%) demonstrated by thin-slice computed tomography scans. More than half of the faulty screws (n=24, 51.1%) were detected in scoliosis patients, especially on the concave side of the curvature (83.3%). The most frequent site of faulty screw placement was the T8 level (21.3%). No symptoms or complications occurred related to faulty screw placement. \\r\\nConclusion: The high accuracy of thoracic pedicle screw placement (94.3%) using the free-hand technique suggests that pedicle screw fixation of the thoracic spine is safe, reliable, and useful in the treatment of all types of spinal diseases.\n\n\u00d6zet\n\nAma\u00e7: \u00c7e\u015fitli omurga sorunlar\u0131n\u0131n tedavisinde torakal pedik\u00fcl vidalar\u0131 ile tespitin di\u011fer tespit y\u00f6ntemlerine g\u00f6re bir\u00e7ok avantaj\u0131 vard\u0131r.
