Sambata trecuta, cu ocazia examenului de chirurgie pediatrica, am avut ocazia de a participa la un simpozion la Spitalul de Pediatrie “Marie S. Curie” , simpozion dedicat unei noi premiere chirugicale in Romania.
Este vorba despre TSF- Taylor Spacial Frame, un fixator osos pentru corectarea diformitatilor, care desi pe piata de 10 ani, a fost adus pentru prima data in Romania si a fost folosit sambata de catre domnul Dr. Burnei. Imi pare sincer rau ca nu am avut echipament la mine ca sa pot asista la interventia in sine dar ma bucur ca am putut lua parte la prezentarea TSF-ului.
TSF este unul din cei mai noi membrii ai familiei Ilizarov, functioneaza pe modelul unui hexapod si este controlat in detaliu de un program computerizat web-based, evitandu-se reinterventiile si schimbarea cadrelor si inelelor ca in cadrul folosirii unui Ilizarov clasic. Dispozitivul are doua inele-unul distal si unul proximal (vezi imagini) si 6 bare de dimensiuni diferite. Costurile unui TSF sunt destul de ridicate, 3000-5000 euro.

The Taylor Spatial Frame (TSF) is an external fixator and shares a number of components and features of the Ilizarov apparatus The TSF is a hexapod device based on a Stewart platform and was invented by Dr Charles Taylor. The device consists of two TSF rings made of aluminium connected together by 6 struts. Each strut can be independently lengthened or shortened. Connected to a bone by wires or half pins, the attached bone can be manipulated in 6 axes (anterior/posterior, varus/valgus, lengthen/shorten.) Both angular deformities and translational deformities can be corrected with the TSF.
It is used in both adults and children. It is used for the treatment of acute fractures, mal-unions, non uniona and congenital deformities. It can be used on both the upper and lower limbs. Specialised foot rings are also available for the treatment of complex foot deformities.
Once attached to the bone, the deformity is characterised by studying the postoperative x-rays. The angular and translational deformity values are then entered into specialised software along with paramaters such as the ring size and initial strut lengths. The software then produces a “prescription” of strut changes that the patient follows. The struts are adjusted every day by the patient. Typically, correction of the bone deformity will take 3-4 weeks. Once the deformity has been corrected, the frame is then left on the leg whilst the bone heals, typically this will take 3-6 months, depending on the nature and degree of deformity.
A Taylor Spatial Frame (TSF)  is the ring fixator introduced to the market by Smith and Nephew, Tennessee, USA, Figure 1. Its main structure is based on the Stewart-Gough platform [2, 3] and consist of two rings and six variable-length struts. The TSF’s main application has been multiplanar deformity correction, although it is being used increasingly for fracture management.
