Fixation for mildly displaced intraarticular fracture of the styloid process of the 5th met?

Fixation for mildly displaced intraarticular fracture of the styloid process of the 5th met?

• A. K-wire fixation
• B. Tension band wiring
• C. Plate fixation
• D. Screw fixation

Answer: (B)

Stability across a mildly displaced intraarticular base fracture of the fifth metacarpal styloid must be achieved with a method that provides reliable compression of the small fragment without disturbing the joint surface. Tension band wiring does this best. By looping a wire in a figure‑of‑eight pattern across the fracture, it converts distracting forces into compressive forces at the fracture line as the finger moves. This gives solid fixation of the tiny, articular fragment while preserving the joint surface and allowing early motion. K-wires alone tend to be less stable because they don’t provide ongoing compression and can migrate. Plate fixation is more invasive and unnecessary for such a small fragment, with a higher risk of cartilage injury or hardware irritation. Screws require enough bone purchase in a small styloid fragment and can risk penetrating the joint, making them less practical in this scenario. So, tension band wiring offers the right balance of stability, joint preservation, and early functional use for this injury.
