Systems and methods for intra-operative image analysis

Abstract

A system and method for analyzing images to optimize orthopaedic functionality at a site within a patient, including obtaining at least a first, reference image of the site, or a corresponding contralateral site, the first image including at least a first anatomical region or a corresponding anatomical region. At least a second, intra-operative results image of the site is obtained. At least one point is selected to serve as a reference for both images during analysis including at least one of scaling, calculations, and image comparisons.

What is claimed is: 
     
         1 . A system to provide intraoperative analysis related to an acetabular component, the system comprising:
 a memory, and   a processor coupled to the memory, wherein the processor is configured to:   obtain an image of a surgical site of a patient with the acetabular component installed;   identify the acetabular component in the image, wherein identifying the acetabular component comprises determining an acetabular component bottom and including a plurality of positioning arcs corresponding to the acetabular component bottom in the image; and   determine anteversion information based on the positioning arcs.   
     
     
         2 . The system of  claim 1 , wherein the processor is further configured to display guide handles to facilitate position adjustment of at least one of the positioning arcs. 
     
     
         3 . The system of  claim 1 , wherein the processor is further configured to display a slider control to facilitate size modification of the positioning arcs. 
     
     
         4 . The system of  claim 3 , wherein the processor is further configured to contemporaneously update the anterversion information in response to the size modification of the positioning arcs. 
     
     
         5 . The system of  claim 1 , wherein the processor is further configured to determine an abduction angle, wherein the abduction angle is formed at the intersection of a neutral axis line and an abduction line. 
     
     
         6 . The system of  claim 5 , wherein:
 with the slider control at one end of the slider range, the positioning arcs overlay the abduction line, and   with the slider control at another end of the slider range, the positioning arcs overlay a hemispherical surface of the acetabular component in the image.   
     
     
         7 . The system of  claim 5 , wherein to determine the abduction angle, the processor is configured to determine a left ischial tuberosity and a right ischial tuberosity in the image. 
     
     
         8 . The system of  claim 7 , wherein the neutral axis line touches a left ischial tuberosity and a right ischial tuberosity in the image. 
     
     
         9 . The system of  claim 5 , wherein the abduction line runs along the acetabular component bottom in the image. 
     
     
         10 . The system of  claim 1 , wherein the acetabular component comprises one of a standard acetabular cup, or a reamer, or a trial acetabular cup 
     
     
         11 . A processor-implemented method to provide intraoperative analysis related to an acetabular component, the method comprising:
 obtaining an image of a surgical site of a patient with the acetabular component installed;   identifying the acetabular component in the image, wherein identifying the acetabular component comprises determining an acetabular component bottom and including a plurality of positioning arcs corresponding to the acetabular component bottom in the image; and   determining anteversion information based on the positioning arcs.   
     
     
         12 . The method of  claim 11 , further comprising displaying guide handles to facilitate position adjustment of at least one of the positioning arcs. 
     
     
         13 . The method of  claim 11 , further comprising displaying a slider control to facilitate size modification of the positioning arcs. 
     
     
         14 . The method of  claim 13 , further comprising contemporaneously updating the anterversion information in response to performing size modification of the positioning arcs. 
     
     
         15 . The method of  claim 11 , further comprising determining an abduction angle, wherein the abduction angle is formed at the intersection of a neutral axis line and an abduction line. 
     
     
         16 . The method of  claim 15 , wherein:
 with the slider control at one end of the slider range, the positioning arcs overlay the abduction line, and   with the slider control at another end of the slider range, the positioning arcs overlay a hemispherical surface of the acetabular component in the image.   
     
     
         17 . The method of  claim 15 , wherein determining the abduction angle comprises determining a left ischial tuberosity and a right ischial tuberosity in the image, wherein the neutral axis line touches the left ischial tuberosity and the right ischial tuberosity. 
     
     
         18 . A non-transitory computer-readable medium comprising executable instructions to provide intraoperative analysis related to an acetabular component by configuring a processor to:
 obtain an image of a surgical site of a patient with the acetabular component installed;   identify the acetabular component in the image, wherein identifying the acetabular component comprises determining an acetabular component bottom and including a plurality of positioning arcs corresponding to the acetabular component bottom in the image; and   determine anteversion information based on the positioning arcs.   
     
     
         19 . The computer-readable medium of  claim 18 , wherein the executable instructions further configure the processor to display a slider control to facilitate size modification of the positioning arcs. 
     
     
         20 . The computer-readable medium of  claim 19 , wherein the executable instructions further configure the processor to contemporaneously update the anterversion information in response to the size modification of the positioning arcs.
