Minimally Invasive Osteosynthesis of Transtrochanteric Fractures with Dynamic Hip Screw (DHS)^*

Abstract

The method presented here consists of a minimally invasive surgical technique for osteosynthesis of transtrochanteric fractures with Dynamic Hip Screw (DHS) 135º. It is indicated in the treatment of 31-A1 and 31-A2 fractures (Arbeitsgemeinschaft für Osteosynthesefragen Classification - AO) that meet the prerequisites required for using DHS. The surgery is performed, preferably, before 48 hours after the fracture. With the use of the same instruments as the traditional surgical technique and the aid of the C-arm, a closed reduction of the fracture and implantation of the DHS is performed by a 2-cm surgical incision, through dissection of the underlying tissues, with minimal bleeding and damage to the soft parts. In the immediate postoperative period, the patient is encouraged to orthostatism and walk with full load, which anticipates hospital discharge and favors early functional rehabilitation. Outpatient return is scheduled at 2, 6, 12 and 24 weeks postoperatively, with radiographic evaluation to assess fracture healing.
