Injectable CPC with arthroscopy in treatment of collapsed tibial plateau fracture

Abstract

Objective To observe the clinical efficacy of using injectable CPC filled bone defects with arthroscopically assisted to treat the collapsed tibial plateau fracture.Methods Thirty-five cases of collapsed tibial plateau fracture were treated from 2004 to 2009.Which Schatzker Ⅱ 23 cases, Schatzker Ⅲ 9 cases, Schatzker Ⅳ 1 case, Schatzker Ⅴ 2 cases.After arthroscopic-assisted reduction, filling injectable CPC, through the window drilled under the articular surface and Schatzker Ⅱ, Ⅳ, Ⅴ were fixed with buttress plate.Results Thirty -four cases of postoperative incision got healing Ⅰ, 1 case of skin necrosis and the exposed parts of plants performed, Ⅱ Phase flap healed after the skin transferring.Followed up 12 -18 months, 35 patients had received fracture healing, no fracture or collapse re -occurred, no internal fixation loosening or broken and so on.According to HSS knee function evaluation based on the results: excellent in 25 cases, good in 7 cases, fair in 2 cases and poor in 1 case.Excellent rate got to 91.4%.Conclusions The method arthroscopically assisted using injectable CPC filling bone defects to treat collapsed tibial plateau fracture character as less traumatic, can discover and deal with intra -articular complications in operation,filling material has a good biocompatibility and can provide immediate stability, while avoiding defects of the autologous bone or allogeneic bone, the patient is easier to accept, and rapid recoverypostoperativeis a ideal measure to cure the collapsed tibial plateau fracture.
