DOS Kongressen 2019 · 207 The association between quality of Tension band wiring and complications Kia Cirkeline Møller Hansen, Jensen Stefan, Viberg Bjarke Department of Orthopaedic Surgery and Traumatology , Kolding Hospital Background: Tension band wiring (TBW) is the most frequently used fixation for displaced olecranon fractures. TBW is in general terms known as a simple method that can be performed by most orthopaedic surgeons and has satisfy- ing results. Purpose / Aim of Study: The aim of this study was to determine if the quality of TBW for displaced olecranon fractures in adult patients was associated with an increase in complications. Materials and Methods: Eligible patients were retrieved using elbow and olec- ranon fracture diagnosis codes from the hospital administration database. From 2013 to 2018 we found 155 patients and excluded 73 patients due to plate fixation and 21 due to other fracture diagnoses. Patient health care files were reviewed for demographics and complications defined as reoperations or loss of fixation within 6 weeks. Pre- operative x-rays were reviewed for classification and postoperative x-rays were evaluated quality of TBW based on 10 imperfec- tions. Findings / Results: A total of 61 patients were included, 21 males and 40 females. The median age was 64 (InterQuartileRange 26-74 and 78% were ASA≤2. There were 39 Mayo type 2A and 22 type 2B. 40 (66%) had post- operative complications. Of them were 31 (51%) minor: 7 (11%) had loss of fixation within 6 weeks (no hardware removal or reoperation) and 24 (39%) needed hardware removal after 6 months due to pain or loss of range of mo- tion. 9 (15%) had major complications: 6 (10%) with hardware removal within 8 weeks, 1 (2%) needed reosteosynthesis, and 2 (3%) had deep infection. The quality of osteosynthesis had in the group with osteosynthesis problems (loss of fixation, reosteosynthesis, and hardware removal within 8 weeks) 0% with 0 imperfection, 50% had 1-2, 36% had 3-4, and 14% had 5 or more. The oth- er surgeries had in comparison 9% with 0 imperfection, 53% had 1-2, 32% had 3-4, and 6% had 5 or more which lead to no association between the two groups (p=0.78). Conclusions: In total 66% of the patients had complications and there were no association with the quality of osteosynthesis and osteosynthesis related complications. The outcome of traditional TBW is therefore questionable in the present cohort. 164.
