Sistema MINUS® - técnica minimamente invasiva para o tratamento das fraturas transtrocanterianas do fêmur

Abstract

The authors declare that there was no conflict of interest in conducting this work ABSTRACTThe MINUS system was developed as a minimally invasive procedure that uses a diaphyseal cephalic extramedullary implant for the treatment of transtrochanteral fractures of the femur in elderly patients. The implant consists of a sliding screw coupled to a plate adapted to the minimally invasive technique. The surgical access is approximately three centimeters in length located on the lateral surface of the hip, below the projection of the small trochanter. A perfectly adapted instrument was used for the procedure, which also requires the use of an image intensifier, reducing surgery time and rate of bleeding. The objective of this study is to present a new instrument and implant, developed specifically for treatment with the minimally invasive technique, reducing the length of the conventional surgical access from 10 to three centimetres. This new implant was given the commercial name of MI-NUS System.

Osteossíntese minimamente invasiva de fraturas transtrocantéricas com Dynamic Hip Screw (DHS)

“…Osteosynthesis of the transtrochanteric fracture using the conventional technique (open reduction and internal fixation with DHS-135°) uses an incision that varies from 10 to 14 cm, which determines the long duration of the surgery, high aggression to the soft tissues and massive blood loss. 3,7,8 Minimally invasive techniques, in turn, bring several benefits to orthopedics, such as: less soft tissue injury and blood loss, as well as reduced risk of infections and duration of surgery. In addition, they allow early rehabilitation, with a consequent decrease in the risk of postoperative complications.…”
