Method of screws installation into specified locations during osteosynthetic therapy of fractures of calcaneus fractures

Abstract

Method of screws installation into specified locations during osteosynthetic therapy of fractures of calcaneus fractures

Dubinsky A.V.

  Depressed calcaneus fractures tend to reveal comminuted nature, and are accompanied by apparent  oedema of soft tissues in the ankle joint and foot zones. Rigidity of calcaneus fracture fixation and ability of an early performance of graduated weight bearing by a certain extremity depend on the precision grade of clamp location in the main splinter body. Presently, this problem is solved by means of an electric-optical image converter application. A method, and an appliance for its practical implementation are being offered, which will provide for an increased precision of a crew/wire installation into the calcaneus, with a simultaneous reduction of radiation exposure on both surgeon and patient. 35 patients with depressed calcaneus fracture were operated according to this method; a therapy result for the period from 6 months to 2.5 years has been made for 8 thereof. The algorithm of therapy did not foresee the external immobilization, the graduated weight bearing commenced after 1.5 months, and the complete weight bearing started after 2.5 months. Redislocation of splinters has not been noticed in any of the cases considered. The appliance offered ensures a high quality of surgical therapy.
