The investigation focussed on determining the influence of geametrically varying configurations in axial wrench (consisting of axial torque and axial force) applied on the kinematics (as defined by the migrating instantaneous helical axis, IHA) of lumbar motion segments under constant resulting axial force, and relating IHA-migration to anatomical structures. In all segments, IHA migrated over several centimetres (up to 6 cm). The main portion of IHA-migration was linked to the angle of rotation interval of +/- 1 degrees. 3. The shape of the IHA-migration was greatly dependent upon the position of the force line F(2). The-force-wrench-dependent wide IHA-migration found for the rotational angle interval of +/- 1 degrees suggests that joint guidance predominates in segment kinematics. The segment kinematics can be adjusted by means of the geometrical configuration of the force wrenches. The design of non-fusion spine implants and FE calculations have to take into consideration joint guidance and muscular force distributions with small intervals of axial rotation."],["dc.identifier.isi","000277171500011"],["dc.identifier.pmid","20400794"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/6046"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/55803"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","0867-5910"],["dc.relation.orgunit","Universitätsmedizin Göttingen"],["dc.rights","Goescholar"],["dc.subject.ddc","610"],["dc.subject.mesh","Aged"],["dc.subject.mesh","Humans"],["dc.subject.mesh","Lumbar Vertebrae"],["dc.subject.mesh","Middle Aged"],["dc.subject.mesh","Range of Motion, Articular"],["dc.subject.mesh","Rotation"],["dc.subject.mesh","Stress, Mechanical"],["dc.subject.mesh","Torque"],["dc.subject.mesh","Torsion, Mechanical"],["dc.title","AXIAL ROTATION IN THE LUMBAR SPINE FOLLOWING AXIAL FORCE WRENCH"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

The aim of the study was to discuss the mechanisms of circumduction and axial rotation of the CMCJ considering geometrical properties of the articulating surfaces and the configuration of the muscle system acting over the CMCJ. 28 CMCJ from 7 female and 7 male corpses (age: 81 yrs (median), 53-91 yrs (interval), which did not show any sign of arthrosis, were investigated. Contours in flexion/extension: in saddle point O, the contour of the proximal surface is stronger curved. For 23 of the 28 joints the contours showed an eye-catching difference. Contours in ab-/adduction: all 28 joints showed the respective incongruity. Straight lines and their included angles: in both articulating surfaces, the angles between the straight lines through the saddle point showed values which were close to 90°. Out of neutral position a small axial rotation (maximal range: 3.5°) is possible without that the contact at the saddle points is changed. But, when one of the straight lines of the proximal surface meets a respective straight line of the distal surface, the contact \"point\" is enlarged to a contact \"line\". When the axial rotation is further increased, the contact \"line\" splits into two contacts \"points\", which are located at outer areas of the articulating surfaces."],["dc.identifier.fs","568801"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/5937"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/61242"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation.issn","0867-5910"],["dc.relation.orgunit","Universitätsmedizin Göttingen"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject.ddc","610"],["dc.title","Mechanisms of circumduction and axial rotation of the carpometacarpal joint of the thumb"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
