Corrective osteotomies around the knee joint using hexapods

We report on 25 knee joint corrections in 23 patients (12 women and 11 men) using hexapods (Taylor spatial frame) during the period 2016-2023. One patient had a femoral and a tibial fixator at the same time; another patient had a triple fixator at the tibia. The mean age was 32 (6-73) years. 15 left and 10 right corrections were performed. 19 fixators had been applied tibial, 5 fixators femoral, and 1 fixator cross-jointly (for contracture). The indications were 6 congenital complex deformities, 10 posttraumatic complex deformities, 3 pseudarthroses after correction osteotomies, 2 patients with osteomyelitis, 1 knee contracture and 1 infection after fracture osteosynthesis with nails. The forms of correction performed were varizations and valgizations in frontal axis, extension and flexion in sagittal plane, torsional corrections, lengthening also after acute shortening (pseudarthrosis resection) and segmental transport. Acute shortening without lengthening was also treated with the fixator only until bone healing and a Masqualet procedure was bridged with it. The average duration of fixator wear was 144 (31-443) days. All patients were followed up until final metal removal. There were 19 change of procedure to another osteosynthesis procedure (18 plate osteosynthesis, 1 ESIN); 6 times the treatment in TSF (Taylor Spatial Frame) was performed until final bone healing.PMID:37947855 | DOI:10.1007/s00064-023-00836-4
