Background:
Despite a sufficient number of papers on the technique of transtibial amputations, the technique of Ertl-type reamputation in short tibial stump remains unreported.
Aim:
To propose a modification of the Ertl operation in the proximal tibia.
Case Presentation:
The technique of bone bridge creation in a patient with a malformed stump in the upper third of the tibia at the expense of the regenerate formed after corticotomy of the tibial remnant and dosed distraction of the graft by the Ilizarov apparatus is described. Radiological, ultrasound and MRI methods were used to control the regenerate. The follow-up period was 36 months. At 3.5 months, a synostosis was formed, which allowed primary and then permanent prosthesis with a full-contact prosthesis. At 36 months, the organotypic remodelling of the regenerate was completed. The patient works, uses the prosthesis for 15-16 hours a day, and walks on average 8-10 km.
Conclusion:
The use of the proposed method makes it possible to obtain tibial synostosis without their shortening with elimination of valgus deviation of the fibula stump and the possibility of early functional loading. Synostosis formation occurs within 3.5 months after surgery. Organotypic bone remodelling occurs during primary and then permanent prosthetics. The formed bone bridge has a large support area, which is maintained during the whole follow-up period of 36 months and allows to perform full-contact prosthetics with maximum load on the residual limb end.
