Sternal dehiscence after median sternotomy is a challenging problem in situations of frail bone, fractures, or complete sternectomy. Plate osteosynthesis offers a promising approach to restore sternal integrity. However, there is only scarce data on mid-term outcome.Mid-term data on 34 patients with unstable thorax after open heart operation, requiring sternal refixation with the Synthes Titanium Sternal Fixation System (Oberdorf, Switzerland) between 2005 and 2011, were analyzed. The Titanium Sternal Fixation System was used if conventional rewiring had failed or if failure of rewiring was expected because of risk factors. Follow-up examinations included clinical tests, computed tomographic scans, and pain assessment to evaluate sternal integrity and persistent pain.Median follow-up time was 1.4 years (range, 0.3 to 6.6 years). Clinical examination showed thoracic stability in all patients. Computed tomographic scans demonstrated complete bone consolidation in 25.8%, nearly complete in 38.7%, partial in 9.7%, and missing in 25.8% of patients. Pain assessment revealed no sternal pain in 16 patients (48.5%), mild pain in 9 (27.3%), moderate pain in 3 (9.1%), and severe pain in 5 patients (15.1%). Pain on movement was reported in 12 patients and 5 patients had chronic pain. A total of 13 patients (38%) required plate removal due to pain (n = 8) or infection (n = 5) after a median of 10.9 and 2 months, respectively.With the use of plates, it was possible to achieve thoracic stabilization in complicated dehiscence. However, the rate of postoperative infection and pain is not negligible. Thus, we recommend plate reconstruction only in sternal high-risk patients, who are unsuitable for standard reclosure.     «
