Objective To investigate the effectiveness of Nice knot combined with elastic intramedullary nailing fixation in treatment of Robinson type 2B midshaft clavicular fracture in adults.Methods Between March 2016 and January 2018, 20 patients with Robinson type 2B midshaft clavicular fractures were treated with reduction and internal fixation by Nice knot and elastic intramedullary nailing. There were 13 cases and 7 cases, with an average age of 43 years (range, 18-56 years). The causes of injury included the traffic accident in 6 cases, falling in 12 cases, and falling from height in 2 cases. The interval between injury and admission ranged from 1 hour to 2 days (mean, 3.2 hours). The fractures were classified as Robinson type 2B1 in 16 cases and type 2B2 in 4 cases. The length of incision, the operation time, the visual analogue scale (VAS) score on the 2nd day after operation, the fracture healing time, the postoperative shoulder function and the Disability of Arm Shoulder and Hand (DASH) score, the complications, and the time of second surgical removal of internal fixator and incision length were recorded.Results The length of incision was 2-6 cm (mean, 4.7cm). The operation time was 45-120 minutes (mean, 77.2 minutes). The VAS score was 1-5 (mean, 3.2) on the 2nd day after operation. All incisions healed by first intention and no infection or nerve injury occurred. All patients were followed up 12-32 months (mean, 18.6 months). All fractures healed with the healing time of 10-15 weeks (mean, 12.1 weeks). The Constant score was 92-98 (mean, 96.3) and DASH score was 0-6.4 (mean, 3.1). The elastic intramedullary nailing bending and hypertrophic nonunion occurred in 1 case and the skin stimulated by elastic nail tail in 1 case after operation. The internal fixators were removed at 12-26 months (mean, 14.6 months) after operation. And the length of incision was 1-2 cm (mean, 1.3 cm) and the operation time was 5-15 minutes (mean, 9.0 minutes). Conclusion For the midshaft clavicular fracture in adults, the procedure of the Nice knot combined with elastic intramedullary nail has advantages of small incision, light pain, rapid fracture healing, small secondary operation injury, and avoiding the risk of clavicular epithelial nerve injury, and can obtain good effectiveness.
