[Biomechanical investigations in the assessment of effectiveness of endoprosthesis].

Based on complex biomechanical investigations the authors have brought out clearly that after endoprosthesis in coxarthrosis patients the biomechanical indices concerned with maintenance of posture and kinematics of walking were markedly improved. The remaining light instability, unsteadiness and tension when standing and walking require strict individualization, sequence, loading of the locomotor apparatus.
