Selectivity Treatment Of Patellar Fractures With Cable-Pin System

Objective:To study the effects of Cable-pin system used as a treatment alternative for patellar fractures.Methods:Twenty cases of patellar fracture were operated with the Cable-pin system from March 2008 to March 2010. Their diagnosis was 15 transverse close fractures and 5 comminuted of patella. There were 14 males and 6 females. Their ages ranged from 21 to 75 years old. As cases of transverse close fractures, after open reduction, the author used a drill bit vertically through the patella in a superior direction, drilled the threaded portion of the pin across the fracture site, and inserted a second Cable-pin through the second hole in a similar manner. A horizontally directed drill hole anterior to the pins was created in the superior pole of the patella. The two cables were crossed in a tighten eight over the anterior surface of the patella. The Crimper Tensioning Handle was, the cable carefully, the handles of the crimper were squeezed until the crimp was fully crimped.5 comminuted of patella can also use Cable-pin as a treatment but with two bone hole.Results:The 20 patients were followed up for 6 to 18 months (mean 12 m). Fractures healed in all the cases without such complications as loosening of screw and cable loop, loss of reduction or irritation to soft tissue. Restoration of the knee joint motion was excellent in 18 cases and good in 2 cases according to Bostman score system.Conclusion:Cable-pin system as a new option for the treatment of patella fracture can result in reliable fixation and low rate of complications with easy operation.
