ObjectiveThe aim of the study was to present the results of osteosynthesis with elastic expandable intramedullary nail for clavicle fractures.MethodsThe study included 17 patients (11 males, 6 females; mean age 36.4 years, range: 21 to 54 years) who underwent surgery for a displaced clavicle fracture and had a shortening of more than 2 cm. The Constant Score and DASH (Disabilities of The Arm, Shoulder and Hand) scoring were used to determine the functional status of the patients.ResultsMean operation time was 30.4 (range: 25 to 42) minutes and mean follow-up period was 10.3 (range: 8 to 19) months. Mean union time was 15.8 (range: 9 to 20) weeks. A superficial infection was treated with wound debridement and antibiotherapy in one patient. No patient suffered from neurovascular compromise, deep infection or implant irritation. Implant fracture developed at 2 months after surgery in one patient treated for Type B1 clavicle fracture and healed without any other intervention. There was no statistically significant shortening (p>0.05). In the final follow-up, the mean Constant Score was 94.3 (range: 86 to 97), and mean DASH score was 11.8 (range: 7.3 to 17.4).ConclusionExpandable elastic locking intramedullary nail appears to provide minimal complication and high success rate for the surgical treatment of non-comminuted displaced clavicle shaft fractures. Additional studies with large series are necessary for further investigation.
