Proximal Ulna/Olecranon — Tension Band Wiring (TBW)
Indication: simple, non-comminuted transverse olecranon fractures (AO 21-B1) with intact dorsal cortex. Principle: converts triceps tensile force into compression at the articular fracture line during elbow flexion. Technique: two parallel K-wires + figure-of-8 wire anterior to axis. Avoid in comminution, osteoporosis, or Monteggia — plate preferred. Complications: hardware prominence, wire migration, loss of reduction, stiffness.
