Fractures of the distal tibia treated with closed reduction and minimally invasive plating

Introduction The treatment of fractures of the distal tibia can be problematical because of the thin soft-tissue covering. Bridging slide-insertion plate osteosynthesis is performed by indirect, axially correct reduction of the fracture and stabilization without opening the soft tissue at the fracture site. Stripping of the periosteum is thus avoided, the fragments remain integrated into the soft tissue, and healing occurs spontaneously by way of callus formation.Materials and methods Seventy-one patients treated by slide-insertion plate osteosynthesis were followed up over at least 2 years. As would be expected in this anatomical region, the proportion of C fractures and fractures with concomitant soft-tissue damage was high. The majority of patients were treated by application of an external fixator on the day of the accident; the definitive osteosynthesis with the slide-insertion plate was performed at a later date after healing of the soft tissues.Results In 68 patients, fracture healing was achieved within 2 years. In 80% of the cases, the final X-ray follow-up showed no or tolerable axis deviations (<5°) in the varus/valgus plane or in the recurvation/antecurvation plane. A deviation >10° requiring a correcting osteotomy was found in only 1 patient. Postoperative complications were rare occurrences. Five patients required an additional cancellous bone graft to deal with inadequate bone healing. System-related complications (instability, malalignment) due to intraoperative technical errors only had to be corrected in revision operations in 2 patients.Conclusion Closed reduction and minimally invasive plating offers the combined advantages of minimal soft-tissue damage with stable fracture fixation.
