Enclouage verrouillé du tibia [Interlocking nailing of the tibia]

Centromedullary nailing is a well-established method of treatment for diaphyseal long bone fractures. The indications have been broadened greatly since the introduction in 1974 of interlocking centromedullary nailing. The purpose of this paper is to review our first results with locked intramedullary nailing of the tibia. We report our experience with the first 19 cases of interlocking tibia nails (15 fractures, 1 delayed union, 2 pseudarthrosis, 1 osteotomy). On the extension table, the insertion of the nail and the placement of the interlocking screws did not cause any problem. In 3 cases, a proximal screw had to be removed within two weeks because of spontaneous displacement. Complications have been noticed in three patients (15.8%) (pulmonary embolism on day 1, and compartment syndrome two days later in one case, sciatic nerve neuroapraxia in the other two). The other patients have been mobilized 24 to 48 hours after surgery. 94% of the fractures were consolidated 4 months post-operatively, with no major deformation. Interlocking tibia nailing seems to be an attractive method in the treatment of certain fractures of the tibia. Early mobilisation and weight-bearing are provided. The indications, the technical aspects as well as the dangers of the method must be carefully respected in order to avoid complications and poor results.
