AKTEKIN ORIGINAL STUDY Is there any difference between the biomechanical strengths of the current fixation techniques for comminuted distal patellar fractures? (Comparison of distal patella fracture fixation techniques) Onur KOCADAL, Murad PEPE, Zafer GUNES, Ertugrul AKSAHIN, Semra DURAN, Cem Nuri AKTEKIN From the Ankara Training and Research Hospital, Ulucanlar, Ankara, Turkey In this biomechanical study, the strength of five surgical treatment for the patella inferior pole different fixation techniques -anterior tension band fractures (15). Internal fixation of the distal part, if wiring with K-wires, separate vertical wiring, headless possible, or excision of the small bone fragments compression screws with anterior tension band with repair of the patellar tendon by transosseous wiring, cannulated screws with tension band wiring pull-out sutures, in the extremely comminuted and memory shape patellar fixator- for distal patellar cases, should be performed (17). However in the fractures were compared. Forty calf knees were used for the biomechanical testing. Each specimen latter, non-absorbable synthetic sutures and partial was pre-loaded with 10 N at 1 N/s. The distraction patellectomy necessitate immobilization of the forces were applied consistently with the velocity of 5 knee, which causes weakness in the quadriceps mm/s. The ultimate load (N) and displacement (mm) muscle (7,14,17,30). Therefore, fixation of the distal values were recorded. The headless compression patellar fractures has gained popularity over partial screw with anterior tension band wiring (656.9±167.9 patellectomy. N) and the cannulated screws with anterior tension There are various previously defined surgical band wiring (642.6±166.0 N) obtained significantly fixation options for patella inferior pole fractures: higher ultimate loading values compared to the other anterior tension band wiring, combining screw fixation methods (p<0.05).
