The purpose of this study was to focus on gait pattern abnormalities in hip-joint arthrodesis patients and correlate them with a normal population similar in age and sex. The importance of a long-term follow-up (in this case, 20 years) is to assess the presence of secondary degenerative arthrosis in joints which are biomechanically and anatomically correlated to the fused hip. It is found that basic gait abnormalities are due to kinematic and kinetic alterations that are the result of compensatory mechanisms used to overcome the lack of hip flexion-extension, ab-adduction and external-internal rotation. The hip-joint arthrodesis patient gait is characterized by an increased sagittal and transverse rotation of the pelvis, increased motion of the sound hip, and a decreased omolateral knee extension during the first part of the stance phase.

Abstract
The purpose of this study was to focus on gait pattern abnormalities in hip-joint arthrodesis patients and correlate them with a normal population similar in age and sex. The importance of a long-term follow-up (in this case, 20 years) is to assess the presence of secondary degenerative arthrosis in joints which are biomechanically and anatomically correlated to the fused hip. It is found that basic gait abnormalities are due to kinematic and kinetic alterations that are the result of compensatory mechanisms used to overcome the lack of hip flexion-extension, ab-adduction and external-internal rotation. The hip-joint arthrodesis patient gait is characterized by an increased sagittal and transverse rotation of the pelvis, increased motion of the sound hip, and a decreased omolateral knee extension during the first part of the stance phase.
