Management of displaced comminuted patellar fracture with titanium cable cerclage.
Management of a displaced comminuted patellar fracture is challenging. Tension band wiring and lag screw fixation are not suitable for such a fracture pattern. Stainless steel wiring with various configurations has been the mainstay of treatment. However, issues of loss of fixation and breakage of wire have not been resolved yet. Partial or total patellectomy is the last resort with a detrimental effect on quadriceps power. Braided titanium cable is stronger in tensile strength and better in fatigue resistance than the stainless steel monofilament wire, and the tension of fixation could be controlled by a graded instrument in its application. We used titanium cable to treat 21 consecutive patients with displaced comminuted patellar fracture. Patients were followed up for a mean period of 24 months (12 to 32 months). The mean score at the final follow-up was 27 points (25 to 30) using the Böstman method. There was no complication except breakage of one cable at the sixth week after the operation and the fracture had united despite the breakage. This technique is simple and effective for these difficult fractures and avoided prolonged immobilisation of the knee.
