Abstract  The sliding compression device, a widely used implant in unstable proximal femoral fractures, suffers from two major limitations: excessive collapse and screw cut-out. Commonly attributed reasons for these are lateral wall comminution and single-point fixation, respectively. We report our experience of stabilising 74 unstable trochanteric fractures, of which 46 cases underwent lateral wall reconstruction using a trochanteric stabilising plate (TSP) in combination with a dynamic hip screw (DHS), and 34 cases with an intact lateral wall had a DHS with an additional anti-rotation screw providing two-point fixation. Fracture consolidation was observed in all cases at an average of 13.56 weeks. Overall functional hip score as per the Salvati and Wilson scoring system was >30 points in 55 patients. Lateral wall reconstruction is an important component in stabilisation of unstable trochanteric fractures and a combination of TSP with a DHS appears to be a useful device to achieve this. Addition of an antirotation screw is likely to enhance the stability further by providing two-point fixation.
