2. Introduction
A complex transverse olecranon fracture treated by tension bend wiring technique
Unfortunately, there was no anterior bony buttress against the compression force of the articular surface of the trochlea, and the secondary reduction loss occurred.

3. Purpose complex transverse fracture of olecranon
the Schatzker type B fracture
articular impacted-depression fragment
To report the clinical outcome of our method
“ tension band wiring fixation after conversion to a simple transverse facture by anatomical restoration of articular fragments using absorbable pins supplemented with autologous bone graft”

4. Inclusion criteria: typical image pattern of the complex transverse olecranon fractures
We confirmed joint-impacted fragment in coronal view in 26 patients by using preoperative simple X-ray and 3D-CT
an articular impacted fragment for olecranon notch on sagittal of CT

5. Patients & Method from 2010 to 2016
Indication: complex transverse fracture of olecranon which had joint-impacted fragment
26 cases: Male 15, female 11
Mean age (years): 48 (range: )
Functional outcomes:
- MEPS (Mayo Elbow Performance Score)
- range of the motion of the elbow joint
Radiologic outcomes: simple x-ray

6. An articular impacted-depression fragment was observed
Anatomical restoration of articular fragments using absorbable pins

7. supplemented with autologous bone graft
→ conversion to a simple transverse fracture
→ Tension band wiring
A coronal articular joint congruency was recovered
Active full range of motion of elbow joint was achieved

8. CASE, M/58

9. An articular impacted-depression fragment was observed

10. Anatomical restoration of articular fragments using absorbable pins

11. Fixation by tension band wiring using eyelet pins

12. Immediate postop x-ray

13. POD 4 year

14. Results All fractures were united Union period : 6 weeks (4 - 8 weeks)
Joint subsidence(mm): 2 cases, but no subjective discomport (respectively, 1.2mm and 2.2 mm)
Mean elbow joint flexion : 132 °(range: 110° - 145°)
Mean elbow joint extension: 4 °(range: -10° - 15°)
Implant problems:
migration(0), breakage(0), skin perforation(0)
MEPS score : 94 (range: )
26 cases (96%) achieved a good or excellent outcome

15. Conclusion
Complex transverse fracture of olecranon which has the joint-impacted fragment
anatomical restoration of articular fragments using absorbable pins
supplemented with autologous bone graft
→ conversion to a simple transverse facture
→ tension band wiring
→ Good option!
