Abstract:
Objective To compare curative effect of the improved wire fixed with the memory alloy patella for the treatment of patella fracture.Methods 80 cases of patellar fracture patients in our hospital were selected. 35 cases with treatment of improved wire fixed were divided into group A.Treatment with memory alloy patella for 45 cases were divided into group B The two groups were analysed.Five aspects of the fracture healing time,the knee joint function,complications,treatment and secondary internal fixation device to take out,were compared of the advantages and disadvantages.Results Two groups compared the following, ( 1 ) Fracture healing time:group A ( 13.75 ± 1.32) weeks,group B (13.34 ±1.21)weeks,t=1.458,P=0.149;(2)Rate of the knee joint function:group A was 94%,B group was 96%,Z=0.257,P=0.797;(3) Complications:A,B two groups were 0,Z=0.000,P=0.000;(4) The cost of treatment:RMB (4 435 ±134) of group A,group B was RMB (9 683 ±159),t=-156.350,P=0.000;(5)Patients with secondary surgery in hospital time:in group A (0.0 ±0.0)days,(9 ±0.4)days for B,t=1.000,P=0.000;(6)Costs in patients with secondary surgical treatment:RMB (800 ±102) of group A,group B was RMB (2 979 ±178),t=-64.690,P=0.000.Conclusion Improvement of steel wire is fixed and the memory alloy patella are reliable methods for the treatment of patella fracture.But improved wire fixation treatment costs low,the second operation can be carried out the advantages of small incision minimally invasive surgery, without hospitaliza-tion,and it has clinical value.
