Abstract:
Pseudo-arthroses are disorders of fracture healing after conservative or operative treatment of fractures which are older than 6 months. Decisive for a targeted therapy is a differentiation between aseptic and septic or atrophic, oligotrophic or hypertrophic pseudo-arthrosis. The operative principals include revitalization of atrophic bone fragments, stabilizing reosteosynthesis for instability and the treatment of infection by transformation of a septic into a stabilized or aseptic pseudo-arthrosis.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
