Abstract

Abstract:

BACKGROUND: Serious patellar comminuted fractures can be treated by a number of methods such as cerclage with tension band steel wire or steel wire, or fixation with the nickel titanium patella concentrator and absorption lines, or cerclage with 10# double-loop wire plus fixation with split-type patella claws or with the memory alloy patella concentrator. But it is difficult to achieve strongly fixed effect on patella fractures by these methods.
OBJECTIVE: To investigate the clinical effects of suture with polyester braided wire and cerclage with belt lock cable on serious comminuted patellar fractures.
METHODS: A retrospective analysis was performed on the clinical data of 57 patients with serious comminuted patellar fractures who received suture with polyester braided wire and cerclage with belt lock cable from January 2007 to October 2012. According to AO classification of fractures, there were nine cases of type B3, 22 cases of type C2 and 26 cases of type C3. After satisfactory reduction of comminuted patellar fractures during the operation, firstly we sewed up both sides of the expansion region of quadriceps muscle and stitched on periosteum and prepatellar tissue with thick polyester braided wire followed by patellar cerclage with belt lock cable. According to the stability of fracture blocks, tension band fixation with polyester braided wire was partially added. After the operation, the clinical effects were assessed based on the Bostman score system.
RESULTS AND CONCLUSION: Totally 46 out of 57 cases were followed up with an average of 8 months (4-18 months). All patients obtained bone union within 3-5 months. Wounds healed in the first stage without any infections, and fractures in all patients healed without complications such as implant loosening and skin irritation. According to the Bostman score system, 33 cases were scored excellent, 10 good and three fair. The excellent and good rate was 93.5%. It suggests that treatment of serious patellar comminuted fracture by the combination of polyester braided wire and belt lock cable leads to closely contact fracture sites and reliably fix bone fragments. It can facilitate early postoperative range of motion exercises.
