Abstract
Objective:To compare clinical effects of different fixations in order to provide the best therapeutic choice for comminuted patellar fractures. Methods: From February 2003 to June 2009,56 patients with comminuted patellar fractures were treated with three methods of fixation. Of them, 18 patients (group A ) were treated with Kirschner-wire with steel wire fixation,there were 9 males and 9 females,ranging in age from 32 to 52 years with an average of (47.62±4.82) years; 13 patients (group B) with circular silk thread fixation and plaster immobilization ,there were 3 males and 10 females,ranging in age from 38 to 65 years with an average of (48.58±8.28) years;25 patients (group C) with memory alloy patella holder fixation ,there were 9 males and 16 females,ranging in age from 32 to 68 years with an average of (48.36±9.59) years. According to criteria of B(o)stman, eight indexes were compared, including the range of motion of the knee, pain, walking and so on. Results: All patients were followed up from 8 to 26 months with an average of 15.6 months. All the fractures healed. The B(o)stman scoring of group A, B,C were respectively 26.00±4.16,22.08±5.31,26.44±3.77. The clinical effects of group A and C were better than that of group B(P＜0.05 ). Conclusion:The method of Kirschner-wire with steel wire fixation or memory alloy patella holder fixation can obtain satisfactory effects in treating comminuted patellar fractures because of steady fixation and early function recovery.关键词
