title: [Fractures of the atrophic mandible--a challenge for therapy].
abstract: Because treatment of fractures of the atrophic mandible still today presents significant difficulties and treatment modalities remain controversial, 87 of these consecutive fractures which were treated by an uniform method as compression osteosynthesis were evaluated. A new classification of the degree of atrophy which considers the special interest of fracture treatment is introduced. It is based on a metrical measurement of the height of the mandible in the fracture area. Mandibles of 16 to 20 mm height are classified as class I atrophy, those of 11 to 15 mm as class II atrophy, and those with a height of 10 mm or less as extremely atrophic mandibles or class III atrophy. This simple and reliable classification could also be used in future investigations on the results of different treatment modalities in atrophic mandibles. In our series of 87 fractures of the atrophic mandible which were treated by compression osteosynthesis 97% resulted in a solid osseous union without the need of a second surgical intervention. Three major complications occurred: 1 osteomyelitis and 2 non-unions (the latter in one patient with a double fracture of a class III atrophy mandible). To the best of our knowledge this series is the largest of fractures of truly atrophic mandibles treated by one uniform method. Compared to other treatment modalities compression osteosynthesis produced acceptable results and is recommended as the treatment of choice in fractures of the atrophic mandible.
