Radiographic studies of lateral flexion in the lumbar spine

摘要: Abstract This paper gives an example of practical results which can be obtained by a plane kinematic analysis movement using radiographs. It is in vivo study lateral flexion the lumbar spine. The technique for identifying each vertebra described. methods condensing geometrical and rough data during testing spine are presented. Parameters arising from statistical calculations defined; they allow one to characterize behaviour single disc or whole These numerical parameters calculated case clinically healthy subjects aim establish norms these parameters, also pathological cases well defined another way, as fusion vertebrae, discopathies.
