A Comparative Study Of Modified Tension Brand Wiring And Cannulated Cancellous Screw Fixation In Management Of Transverse Fractures Of Patella.

ABSTRACT

Abstracts Background This study compares the results of two commonly used methods of internal fixation for transverse fracture of patella namely modified tension band wiring (TBW) and cannulated cancellous screw fixation. Methodology: The study consists of 20 cases treated at BRIMS hospital , Bidar with modified tension band wiring with K-wires and cannulated cancellous screws with a follow up of 1 year. Out of 20 cases, Group A consists of 10 patients treated for tension band wiring and Group B of 10 cases treated for cannulated cancellous screws. Results: Union was achieved in all 20 cases. Group A treated 9 out of 10 had excellent to good results with knee flexion more than 120° and Group B, had 8 out of 10 with excellent to good results with knee flexion more than 120°. In all the 20 cases Quadriceps wasting was severe but less in Group A. Discussion: Although the modified tension band technique (eg. tension band supplemented by longitudinal Krischner wires) has long been the mainstay for fixation of transverse fractures of patella. It has shortcomings, such as bad reduction, loosening of implants, and skin irritation. It was found that modified tension band wiring showed better results than cannulated cancellous screws as stability of implants is better in transverse fracture patella and post operative rehabilitation is faster. Conclusion The modified tension band wiring is better than that of Cannulated cancellous screw transverse fractures of patella probably because of good stability of implant and easier postoperative rehabilitation.
