X-ray grid orthometer
| Details |
Inventors: Loeffler, Cecil W.;
Assignee:
Primary Examiner: Little; Willis
Assistant Examiner:
Attorney, Agent or Firm: O'Brien; Clarence A., Jacobson; Harvey B.
An X-ray grid orthometer including a support having a generally horizontal surface over which is disposed a frame swingable from side-to-side relative to a fixed indicator which permits alignment of the frame with an X-ray tube of an associated X-ray machine. The frame can be in the form of a slide bearing, which includes a pair of substantially parallel slides separately mounted on associated slide guides for independent movement, and terminating in foot rests against which can be placed the legs of a person lying on the horizontal support surface in order to obtain an indication of leg length of the person, or the frame can be a four-link parallel-motion mechanism using a pair of parallel links in place of the slides. A weight bearing effect, also known as a spine-limb compression, can be achieved despite the prone position of the patient by use of a flexible element disposed about a pair of pulleys mounted on the support so as to permit the person whose leg lengths are being measured to pull with both hands and, thus, compress the feet thereof against plates of the foot rest. In this manner, visceral obstruction can be reduced by placing the subject in a supine position. |

DETAILED DESCRIPTION It is an object of the present invention to provide an X-ray grid orthometer which duplicates the weight-bearing effect, or spine-limb compression, of a subject in standing position while the subject is supine, thus reducing visceral obstruction, minimizing motion of the subject, and simultaneously registering any anatomical imbalance on the X-ray film with little obstruction, if any, of the radiographic record.
It is another object of the present invention to provide an X-ray grid orthometer which is compact in size and can be readily stored and transported.
Still another object of the present invention is to provide an X-ray grid orthometer which is convenient and simple to use, but which is capable of securing highly accurate results.
A still further object of the present invention is to provide an X-ray grid orthometer which is versatile in that it gives a direct readout of leg imbalance, and the like.
These and other objects are achieved according to the present invention by an X-ray grid orthometer having: a support; a frame mounted on the support for adjusting to the length of the leg of a subject; and an indicator arrangement mounted on the support and slide assembly for registering an imbalance of the length of the legs of the patient.
Perferably, the support includes a horizontal surface on which the subject can lie in a supine position, with the frame including either a linear slide bearing or a four-link parallel-motion mechanism arranged substantially horizontally over the surface of the support and bearing pivotally mounted on the support for swinging movement about a substantially vertical axis.
The frame further includes a post mounted on the support in substantially vertical orientation arranged extending above the horizontal surface of the support.
A clamping arrangement adjustably mounts on the post for supporting the frame, while a bracket is secured to the post vertically below the clamp arrangement for mounting the post on the support.
One embodiment uses a slide bearing which advantageously comprises a pair of spaced, substantially parallel, coextensive, stationary slide guides affixed to the support, with a pair of slides mounted on the slide guides, one of the slides to a respective one of the guides
