ABSTRACT
Objective To evaluate the clinical effects of open reduction plate screw nail internal fixed and minimally invasive elastic intramedullary nail internal fixation combined with neck strap suspension for treating adult humeral shaft fracture . Methods A retrospective analysis was made on the clinical data of 65 patients with humeral shaft fracture in our hospital from March 2012 to March 2014 ,including 38 cases of open reduction plate screw internal fixation (plate screw nail fixation group) and 27 cases of limited open or closed reduction elastic intramedullary nail internal fixation combined with neck strap suspension (elastic intramedullary nail group) .The operation time ,intraoperative blood loss amount ,iatrogenic radial nerve injury ,occurrence rate of incision infection ,postoperative fracture reduction degree ,fracture recovery time and elbow joint function score were compared be‐tween the two groups .Results The operation time and intraoperative bleeding volume in the elastic intramedullary nail group were less than those in the plate screw nail fixation group ,the differences were statistically significant (P0 .05) ,the postoperative shoulder and elbow joint function scores in the plate screw nail group were significantly higher than those in the elastic intramedullary nail group ,the difference was statistically significant (P<0 .05) .No serious nerve damage ,incision infection and other postoperative complications occurred in the two groups .Conclusion Both the open reduction plate screw nail internal fixation and elastic intramedullary nail in‐ternal fixation are effective method for treating adult humeral shaft fracture ,the latter has shorter operation time ,less intraoperative bleeding ,but shoulder elbow pain and limitation of motion are more serious than the former .
ABSTRACT
BACKGROUND:Humeral supracondylar fracture is a common fracture occurred in children. The selection of internal fixation for humeral supracondylar fracture remains controversial. OBJECTIVE:To compare the biocompatibility between internal fixation with Kirschner wire and bioabsorbable implants for humeral supracondylar fractures. METHODS: From January 2007 to January 2013, 246 cases of humeral supracondylar fractures, from Affiliated Hospital of Luzhou Medical Colege, were treated by internal fixation with Kirschner wire. Meanwhile, the studies on internal fixation for treating supracondylar fracture of humerus in children were searched. Efficacy was evaluated by preoperative and postoperative elbow range of motion and the incidence of cubitus varus, and the results were statisticaly analyzed, and compared with other therapeutic methods. RESULTS AND CONCLUSION:Al cases were folowed up for 6-36 months, averagely 18 months. According to Mayo elbow performance score, function of the elbow joint was excelent in 194 cases, and good in 48 cases, with good and excelent rate being 98.4%. Four cases suffered < 5° cubitus varus, with incidence rate of 1.63%. The internal fixation with Kirschner wire provided functional recovery of elbow joint, but the second stage operation was needed to pick out the wires. And it might be perplexed by Kirschner wire loosening or needle withdrawal, resulting in instable fixation. Bioabsorbable implants were effective in the treatment of supracondylar fracture of humerus. Bioabsorbable sticks would break down over time, without harming to human body or influencing imaging examination. Elbow function development of the epiphysis would not be affected. However, due to lack of large-sample observation, long-term effects of bioabsorbable implants for treating supracondylar fracture of humerus in children deserve further studies.
