Abstract

INTRODUCTION: Implant removal because of pain after posterior fusion in the thoracic and lumbar spine is a widely performed operation. We conducted a retrospective study to examine whether patients benefit from implant removal. PATIENTS AND METHODS: 57 patients (29 males, 28 females, mean age 46.5 years) who have undergone removal of pedicle screws because of pain and discomfort were interviewed 6-24 months postoperatively. Fracture was the initial diagnosis in 40% of the patients and degenerative spine disease in 58%. The following factors were evaluated: patient satisfaction and postoperative outcome, patients' native language and psychological background, operative data, hospital stay and complications. RESULTS: Pain decreased significantly from 62 to 48 on visual analogue scale postoperatively. Complications occurred in five patients (8.8%). 36 patients (61%) stated they had some benefit from the operation, but only seven patients (12%) were free of pain completely. 36 patients (63%) would undergo the same procedure again. Outcome in the subgroup of foreigners was significantly worse, though the psychological background did not affect the outcome. Preoperative diagnostic infiltration was helpful in 9 of 13 patients. CONCLUSION: Removal of pedicle screws because of back pain may be effective, but complete remission of symptoms could be achieved in only 12% of patients. However, 63% of patients would undergo hardware removal again. Preoperative diagnostic infiltration can help to predict the outcome but results are inconsistent. Communication difficulties may worsen the outcome. Surgeons should consider these results when planning implant removal and patients should be informed thoroughly to avoid too high expectations.
