The treatment of intertrochanteric fractures of the femur with Endovis nail
Journal Title: Ortopedia Traumatologia Rehabilitacja - Year 2011, Vol 13, Issue 6
Abstract
SummaryBackground: The incidence of fractures in the trochanteric area has risen with the increasing numbers of elderly persons with osteoporosis. The imperative goals of treatment are early mobilization by means of stable fixation using as minimally invasive a procedure as possible. Nowadays, there is an increasing interest in intramedullary nailing, especially for unstable intertrochanteric fractures. The aim of the present paper is to assess the efficacy of closed intramedullary osteosynthesis with the Endovis® proximal femoral nail in the treatment of peritrochanteric fractures to solve the problems associated with the use of intramedullary fixation devices.Material and methods: The authors describe their experience with 87 stable and unstable proximal extra-capsular femoral fractures treated with the Endovis femoral nail from July 2007 to March 2009. The results were evaluated clinically, functionally and radiographically during the 1st, 3th, 6th and 12th months post-op. Pre-injury activity and functional levels were recorded using the modified Harris hip score and V.A.S. score.Results: Postoperative radiographs showed a near-anatomical fracture reduction in 85% of patients. Three were the cases of cut-out, one case of valgus and two cases of shortening of the operated leg (<1 cm). The Harris Hip Score increased between the thirtieth and ninetieth postoperative day, accompanied by a significant decrease in pain symptoms and functional limitation.Conclusion:1. The application of an intramedullary nail provides primary stability of the fracture. 2. The Endovis nail constitutes a powerful synthesis for stable and unstable fractures of the trochanteric region, in which is difficult to reconstruct appropriate continuity between the medial and posterior cortical layers. 3.The good mechanical stability of the nail allows rapid mobilization and early functional recovery. 4. The presence of an additional anti-rotational screw and the free sliding mechanism of the lag screw may increase rotational stability of cervico-cephalic fragments and decrease overload on the femoral head.
