We studied the use of Ortho-SUV hexapod in the treatment of 15patients with lower limb false joints. All patients were at active working age – from 22 to 50years. In 12patients, the period from the moment of trauma was 1 to 3years, in 3patients – 3 to 6years. 5patients had femoral false joints, 10patients – shin false joints. In 98% of cases, the formation of false joints was caused by inadequate treatment of initial trauma. In 100% of cases, false joint localized at diaphyseal level and was accompanied with shortening of injured segment for 2.5±1.0cm in 13patients, and for 0.5 and 0.8cm in 2cases. We also registered recurvatum and valgus deformity in 5patients, recurvatum and varus deformity in 8patients, and antecurvatum and varus deformity in 2patients. Combined contracture in knee and ankle joint was found in 90% of patients. Using combined transosseous osteosynthesis along with Ortho-SUV hexapod allowed us to correct hip deformity for 35±10days and ankle deformity – for 20±5days on the average. When shortening of femoral bone for more than 5.0cm, the deformity was corrected in two stages. At the first stage, we reconstructed the length of a segment using methods of transosseous osteosynthesis at discrete-continuum distraction. At the second stage, we corrected deformity using Ortho-SUV hexapod within specified time limits. Duration of femoral and shin false joint consolidation was 194±16days. We registered inflammatory complications in the areas of transosseous elements contacting soft tissues in 3(0.2%)patients. These complications didn’t have an effect on the treatment results.
