ABSTRACT
Objective To compare the clinical effect between olecranon osteotomy and bilateral triceps brachii approach combined with bilateral locking plate in the treatment of type C3 distal humerus fracture.Methods Forty-five patients with type C3 distal humerus fracture were performed with operation and follow-up in Department of Osteology of the First People's Hospital of Xinxiang City from July 2006 to February 2016.The patients were divided into olecranon osteotomy group (n =25) and bilateral triceps brachii approach group (n =20).The patients in olecranon osteotomy group were treated with olecranon osteotomy combined with bilateral locking plate,and the patients in bilateral triceps brachii approach group were treated with bilateral triceps brachii approach combined with bilateral locking plate.The incision length,operation time,hospitalization time,fracture healing time,postoperative complications and the score of elbow joint function were compared between the two groups.Results There was no significant difference in the mean follow-up time between the two groups (P ＞ 0.05).The incision length in olecranon osteotomy group was significantly shorter than that in bilateral triceps brachii approach group(P ＜ 0.05).There was no significant difference in the operation time,hospitalization time and fracture healing time between the two groups (P ＞ 0.05).There was one case of infection and two cases of heterotopic ossification in the olecranon osteotomy group,and the incidence of postoperative complications was 12.0％ (3/25).There was one case of heterotopic ossification,one case of fracture delayed union and one case of elbow joint stiffness in the bilateral triceps brachii approach group,and the incidence of postoperative complications was 15.0％ (3/20).There was no significant difference in the incidence of postoperative complications between the two groups (x2 =0.087,P ＞ 0.05).At the end of the follow-up,the excellent rate of the Mayo score of elbow joint function in the olecranon osteotomy group and bilateral triceps brachii approach group was 88.0％ (22/25) and 55.0％ (11/20) respectively,the excellent rate in the olecranon osteotomy group was significantly higher than that in the bilateral triceps brachii approach group (x2 =6.188,P ＜ 0.05).Conclusion Compared with the bilateral triceps brachii approach,the olecranon osteotomy combined with bilateral locking plate fixation is more beneficial to the recovery of elbow joint function in patients with type C3 distal humerus fracture.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the drug resistance of imipenem-resistant (IR) Gram-negative bacilli (GNB) in coal workers' pneumoconiosis (CWP)-chronic obstructive pulmonary disease (COPD) patients with lower respiratory tract infection (LRTI) and to provide a basis for clinical treatment.</p><p><b>METHODS</b>Sixty-six strains of IR-GNB were isolated from the sputum of CWP-COPD patients with LRTI, and the bacterial spectrum was investigated. The drug resistance of bacterial strains was studied by KB disk diffusion method.</p><p><b>RESULTS</b>Among the 66 strains of IR-GNB, 29 (43.9%) were Pseudomonas aeruginosa, 17 (25.8%) were Acinetobacter baumannii, and 11 (16.7%) were Stenotrophomonas maltophilia. The drug sensitivity test showed that all bacteria had high drug resistance; Pseudomonas aeruginosa had a susceptibility rate higher than 50% to ciprofloxacin, polymyxin B, fosfomycin, and amikacin, Acinetobacter baumannii had a susceptibility rate higher than 55% to fosfomycin, polymyxin B, and cefoperazone/sulbactam, Stenotrophomonas maltophilia had a susceptibility rate higher than 50% to cotrimoxazole, ciprofloxacin, piperacillin/tazobactam, levofloxacin, polymyxin B, and cefoperazone/sulbactam, and Pseudomonas cepacia had a susceptibility rate higher than 50% to piperacillin/tazobactam, ciprofloxacin, cefoperazone/sulbactam, and polymyxin B.</p><p><b>CONCLUSION</b>The main species of IR-GNB are such non-fermentative bacteria as Pseudomonas aeruginosa, Acinetobacter baumannii, and Stenotrophomonas maltophilia in CWP-COPD patients with LRTI. These bacteria have high drug resistance and are sensitive to only a limited range of antibiotics.</p>
