What is it indicated for?
The intended use of the modified Long Length Gamma® Nail is identical to that of the predicate Long Length Gamma® Nail: the product is intended to be used in fixation of femoral fractures occurring from the base of the femoral neck extending distally to a point approximately 10 cm proximal to the intracondylar notch. Fracture types include basilar neck, intertrochanteric, subtrochanteric fractures and femoral shaft fractures. These femoral fractures may occur as a result of trauma, non-union, mal-union, pathological fractures, and impending pathological fractures.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
