Reverse LISS plates for unstable proximal femoral fractures

Evaluation of proximal femoral locking plate in unstable extracapsular proximal femoral fractures: Surgical technique & mid term follow up results

“…Various authors have used reverse LISS femoral locking plate 24,25 (Figs. 3 and 4) for unstable fractures of proximal femur but in our experience, this particular implant is not mechanically suited for anatomically sitting on proximal femur.…”

Inverted distal clavicle anatomic locking plate for displaced medial clavicle fracture

“…In our case, we used an anatomic locking plate which was originally designed for the distal clavicle fracture, inspired by excellent results following surgical treatment of proximal femoral fractures by the reversed Less Invasive Stability System [9]. We found that invert the ipsilateral locking plate 180°to placed on the superior aspect of the medial clavicle, it matched the medial clavicle third very exactly, so it does not need any contouring.…”

Combination of modified free vascularized fibular grafting and reverse Less Invasive Stabilization System (LISS) for the management of femoral neck nonunion in patients thirty years of age or younger

“…The LISS has been successfully applied to treat distal femur fractures for more than 10 years, with satisfactory results [17][18][19]43]. Recent publications on the treatment of proximal femoral fractures through the reverse LISS have shown that this technique also has a high union rate with less complication [20][21][22][23][24][25]44,45]. However, whether the reverse LISS is a viable technique to treat femoral neck nonunion remains unknown, With respect to anatomic structure and biomechanical aspects, 'Upside-down' contralateral LISS is not only anatomically fit for proximal femur but also for following the physiological curve of the femoral shaft because the femoral LISS utilizes an anatomical shape plate to treat distal femur fractures, and the shape of the lateral condyle of the femur is similar to the great trochanter [20].…”

“…The Less Invasive Stabilization System for the treatment of distal femurs (LISS-DF, Synthes USA, Paoli, PA) was designed as an optimized fixation for fractures of the knee [17][18][19]. 'upside-down' LISS, so-called reverse LISS, has been successfully employed to treat complex proximal femur fractures [20][21][22][23][24][25]. However, combined procedure of modified FVFG and reverse LISS in the treatment of femoral neck nonunion has not been described so far.…”
