The retrograde intramedullary supracondylar nail: an alternative in the treatment of distal femoral fractures in the elderly?

To find out whether retrograde nailing of distal femoral fractures is beneficial for the aged patient, we performed a prospective study of consecutive patients 65 years or older with distal femoral fracture treated with a retrograde femoral nail between 1 March 1993 and 30 April 1996 in our department. In total, 26 patients with unilateral distal femoral fractures had been treated in our department, and 24 patients had been followed up for more than 12 months. All fractures had healed. Six patients did nor walk before the injury. According to the Neerscore we counted 10/18 excellent results: (greater than or equal to 85 points), 6/18 good results (greater than or equal to 70 points), 2/18 fair results: (greater than or equal to 55 points) and no failures (< 55 points). Retrograde intramedullary nailing makes a biological osteosynthesis of distal femoral fractures possible, Even in our aged patients good functional results could be obtained. Poor hold of the distal interlocking screws and difficult proximal locking are the two major technical problems encountered with this implant. Early weight-bearing is not advisable.
