Closed reduction and percutaneous double K-wires internal fixation for the treatment of multisegmental fracture of humeral shaft / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To observe the clinical effects of closed reduction and percutaneous double K-wires internal fixation in treating multisegmental fracture of humeral shaft.</p><p><b>METHODS</b>From January 2009 to April 2015, 27 patients with multisegmental fracture of humeral shaft were treated with closed reduction and percutaneous double K-wires internal fixation, including 10 males and 17 females, ranging in age from 26 to 81 years with an average of 52 years;the disease course ranged from 2 hours to 6 days with an average of 1.5 days. Operative time, intraoperative blood loss, hospital stay, fracture healed time, complications were observed and recovery of shoulder joint function was evaluated by Constant-Murley shoulder score.</p><p><b>RESULTS</b>All the patients were followed up from 12 to 24 weeks with an average of 16 weeks. Operative time was 20 to 40 min with an average of 28 min; intraoperative blood loss was 5 to 25 ml with an average of 10 ml;hospital stay was 3 to 5 days with an average of 3.5 days. All fractures got bone healing and healed time was 12 to 22 weeks with average of 14 weeks. Postoperatively 1 case complicated with wire tail bulging and local irritation symptoms, and the symptoms disappeared when the wire was removed out after the fracture healing; 1 case complicated with local infection after wire tail disengaging, and recovered through anti-septic treatment. According to the Constant-Murley standard of shoulder joint function, 10 cases got excellent results, 15 good, 2 fair, with scores of 89.1±2.7.</p><p><b>CONCLUSIONS</b>Closed reduction and percutaneous double K-wires fixation for the treatment of multisegmental fractures of humeral shaft have advantages of simpler manipulating, less bleeding, less invasive, less complications, and shoulder and elbow joint can obtain good recovery. But closed reduction and percutaneous double K-wires internal fixation cannot be effective against rotation and provide axial stability, the immoblization with a sling or other auxiliary methods should be applied.</p>
