生长期儿童股骨干骨折髓内针内固定的远期观察

作者从1970～1985年收治生长期儿童股骨干骨折305例,其中切开复位髓内针内固定34例(38处股骨骨折),并进行了5～17年的长期随访观察,发现无1例出现术后早期并发症,12例(占33.3％)出现大粗隆发育受阻的晚期并发症。18例(22处股骨骨折)双下肢等长,13例患肢较健侧长0.8～1.4cm平均1.03cm,1例合并有下肢动脉损伤者出现下肢短缩。作者认为无论采用梅花型髓内针内固定,还是三棱型髓内针内固定都是可行的,但梅花型髓内针内固定有出现大粗隆发育受阻的危险。

The Late Observation of Femoral Fracture Treated by Intramedullary Nailing in the Growing Child

The late results of 34 cases of femoral fracture treated by intramedullary nailing in the growing child were reviewed between 1970~1985 and followed up 5~ 17 years. All were treated by open reduction and retrograde nailing using club shape nailing or "tri-edge" type nailing. There were no early postoperative complication of nailing. The only late complication was growth disturbance of the greater trochanter in twelve cases(33. 3%). Leg length was equal in eighteen children (twenty -two fractures)and differed by0. 8-1.4cm (average 1. 03cm) in thirteen due to stimulation of femoral growth. Both club shape nailing and "tri -flange" type nailing were found to be reliable but the former may carry a risk of growth arrest of the greater trochanter. The later one seemed less damage than the former.
