Abstract
Internal fixation with a trifin nail after displacement osteotomy of the femur permits reduction of external splintage to a degree that any patient can tolerate with ease; it also eliminates the problem of the stiff knee.
The method has been used successfully for recent and old fractures of the femoral neck, for post-irradiation fractures, for failed nailing operations or arthroplastics, for osteoarthritis, for rheumatoid arthritis, for old congenital dislocations and subluxations, and to stabilise the hip after excision of the head and neck to create a pseudarthrosis.
