Claim 1
Independent Claim
216 words
A device for measuring tibial torsion comprising a supportive member having attached thereto on moveable hinged supports at least two hinged members, said hinged members having thereon angle-measuring scales to show the angle between said hinged members and said supportive member, said hinged members having adjustably attached to each at least one positionable cup like structure for placement over the malleoli, said cup like structures to be fastened to said hinged members so that one of the cup like structures can be positioned over the malleoli when said supportive member is placed behind a patient's heel and the respective hinged member is at 90° to said supportive member, said hinged member having on each similar distance scales to ascertain the position of said cup like structure on said hinged member relative to said supportive member, further, the similar distance scales placed to allow the second cup like structure to be positioned precisely the same distance from said supportive member, further, when both said cup like structures are positioned the same distance from said supportive member when said hinged members are 90° to a said supportive member, and said cup like structures are then placed over a patient's malleoli without changing their respective positions on said hinged members, said measuring scales show the extent of tibial torsion.
