Poster Topic: Trauma - Elbow Abstract number: 24263 TENSION BAND WIRING FOR OLECRANON FRACTURE USING A BRAIDED POLYBLEND SUTURE (FIBER WIRE) Umeo NISHIKAWA 1 , Kenji NOZAKI 2 , Koji RYOKE 2 , Yukiko KIRITA 2 , Tadahiko YTSUMOTO 2 1 IHI Harima Hospital, Aioi (JAPAN), 2 Wkakusadaiichi Hospital, Higashiosaka (JAPAN) Olecranon fractures are a common injury and tension band wiring is frequently used. We report the results of surgical treatment for olecranon fractures with a braided polyblend sutures (Fiber Wire, Arthlex, FL, USA) which is a new non-metal material. [Patients and Methods] Between 2006 and 2009 we performed surgical treatment for 15 patients (7 males and 8 females) with olecranon fractures. Their mean age was 55 years old (from 19 to 81 years). All fractures were operated with Fiber Wires and two Kirschner wires or Ring Pins (Nakashima Medical, Okayama, Japan). Two or three days after operation, patients began range of motion (ROM) exercise of elbow joint.At the follow-up we observed the X-ray, complications, ROM of the elbow joint, pain and so on in all patients. The follow-up period ranged from 3 months to 18 months with a mean of 9 months. [Results] No X-ray showed delayed and non-union in all fractures. There were no postoperative complications such as dislocation of bone fragments, displacement of materials, local irritable pain etc. Extension of elbow joint ranged from 0 to -10degree (mean -4 degree), while flexion ranged from 120 to 145 degree (mean 131 degree). All patients did not have severe pain and any skin trouble around olecranon. [Conclusion] We concluded that tension band wiring with Fiber Wire is a useful modality for olecranon fracture. 514

Poster Topic: Trauma - Elbow Abstract number: 24494 BIOMECHANICAL COMPARISON OF LOCKING PLATE OSTEOSYNTHESIS VS. INTRAMEDULLARY NAILING FOR THE FIXATION OF OLECRANON FRACTURES Tobias NOWAK, Klaus BURKHART, Daniela KLITSCHER, Lars MUELLER, Pol ROMMENS Department of Trauma Surgery Johannes Gutenberg University, Mainz (GERMANY) Introduction: Tension band wiring is the standard procedure to treat olecranon fractures. Symptomatic hardware prominence and migration of K-wires cause a high revision rate. Alternative fracture fixation devices were developed. The aim of this study was to evaluate the biomechanical stability of two new designed fracture fixation devices for the treatment of olecranon fractures in dynamic continuous loading. Methods: In eight pairs of fresh frozen cadaver ulnae simulated oblique olecranon fractures were created and stabilized using either a precontured locking compression plate, or an intramedullary locking nail. The specimens were then subjectes to continuous dynamic loading (from 25 to 200 N) performing a matched pairs comparison. The statsistical differences of the displacement in the fracture gap was determined using the Wilcoxon-test.Results: Non of the fracture fixation devices had significant advantages after 300 cycles of continuous loading according to the Wilcoxon-test concerning the paramenter of loosening. Interpretation: Both new implants show a good performance in stability concerning dynamic continuous loading for the simulation of 6 weeks of light physiotherapeutic training in cadaver upper extremities. 515

Introduction: Tension band wiring is the standard procedure to treat olecranon<br />

fractures. Symptomatic hardware prominence and migration of K-wires cause a high<br />

revision rate. Alternative fracture fixation devices were developed. The aim of this<br />

study was to evaluate the biomechanical stability of two new designed fracture<br />

fixation devices for the treatment of olecranon fractures in dynamic continuous<br />

loading. Methods: In eight pairs of fresh frozen cadaver ulnae simulated oblique<br />

olecranon fractures were created and stabilized using either a precontured locking<br />

compression plate, or an intramedullary locking nail. The specimens were then<br />

subjectes to continuous dynamic loading (from 25 to 200 N) performing a matched<br />

pairs comparison. The statsistical differences of the displacement in the fracture gap<br />

was determined using the Wilcoxon-test.Results: Non of the fracture fixation devices<br />

had significant advantages after 300 cycles of continuous loading according to the<br />

Wilcoxon-test concerning the paramenter of loosening. Interpretation: Both new<br />

implants show a good performance in stability concerning dynamic continuous<br />

loading for the simulation of 6 weeks of light physiotherapeutic training in cadaver<br />

upper extremities.<br />
