OBJECTIVETo research the application and clinical effect of titanium elastic nails (TEN) for the treatment of closed clavicular fracture in elder children.

METHODSFrom October 2010 to December 2012,16 elderly children with clavicular fracture of elder children were treated with internal fixation, including 9 boys and 7 girls with an average age of 14.2 yeats old ranging from 9 to 17 years. The mean time between injury and surgery was 2 to 6 days. Thirteen patients had a transverse fractures; 3 patients had a oblique fractures, excluding the long-oblique patients. Neer function score after 3 months follow-up and the shoulder activity degree after 3 weeks followed were compared respectively between the injured side and healthy side. Fracture reduction and healing were followed up by X-rays to analyze internal fixation with TEN technique.

RESULTSAll patients were healed well after surgery. There were 2 cases with soft tissue irritation. No cases of infection, TEN broken, delayed healing or skin bursting were observed. All patients were followed up for 3 to 10 months,with an average of 7.2 months. There were no significant differences (t=2.12, P>0.05) between the healthy side (98.75±2.70) and injured side(96.69±6.22)of Neer score at 3 months during followed up. The shoulder activity at 3 weeks during followed up was different between both sides (P<0.05). The intramedullary nail was removed after X-rays at 12-18 weeks during followed up showed good bone healing,and the shoulder function was recovered well.

CONCLUSIONInternal fixation with TEN for the treatment of clavicular fracture has advantages of a limited invasion, beauty, safety and reliability. This technique provides an ideal fixation option for the treatment of clavicular fracture in elder children.
