Dynamic bone plate compression device and method

Abstract

A dynamic bone plate and method of bone compression are disclosed. The dynamic bone plate comprises a first bone plate component including at least one hole for receiving screws for attachment to a first bone segment and a male component and a second bone plate component including at least one hole for receiving screws for attachment to a second bone segment and a female component for mating with the male component. The male component is adjustable after mating with the female component to adjust a position of the first bone plate component with respect to the second bone plate component and the male component is locked into place with respect to the female component by at least one screw inserted through the at least one hole of the second bone plate component causing compression between the first and second bone segments to form a corrective construct.

         4 . The dynamic bone plate of  claim 3 , wherein the base component further comprises a concave section configured for receiving the multiplanar component, facilitating a ball joint type motion between the concave section and the multiplanar component. 
     
     
         5 . The dynamic bone plate of  claim 4 , wherein the multiplanar component is secured into the base component with at least one screw which may be inserted through both at least one hole of the multiplanar component and at least one hole of the base component. 
     
     
         6 . The dynamic bone plate of  claim 4 , wherein the concave section allows the male component to be placed at varying angles with respect to the base component. 
     
     
         7 . The dynamic bone plate of  claim 1 , wherein the second bone plate component further comprises a ratcheting pawl. 
     
     
         8 . The dynamic bone plate of  claim 7 , wherein the ratcheting pawl restricts movement of the male component within the female component. 
     
     
         9 . The dynamic bone plate of  claim 7 , wherein the ratcheting pawl may be secured by a bone screw inserted and tightened through a hole of the second bone plate component. 
     
     
         10 . The dynamic bone plate of  claim 3 , wherein the male component includes a plurality of grooves. 
     
     
         11 . The dynamic bone plate of  claim 3 , wherein the at least one male component is coupled to the base component with a screw. 
     
     
         12 . The dynamic bone plate of  claim 1 , wherein the first bone plate component comprises a plurality of male components, each male component configured for mating with the second bone plate component. 
     
     
         13 . The dynamic bone plate of  claim 1 , wherein the first bone plate component comprises a recessed hole configured to receive a bone screw that secures both the first bone plate component and the second bone plate component together after the male component has been joined with the female component. 
     
     
         14 . A dynamic plate, comprising:
 a first plate component, comprising:
 at least one hole configured for receiving at least one screw for attachment to a first body segment; and 
 a male component; 
   a second plate component, comprising:
 at least one hole configured for receiving at least one screw for attachment to a second body segment; and 
 a female component configured for mating with the male component of the first plate component; 
   wherein the male component is adjustable after mating with the female component to allow movement between the first plate component and the second plate component, and wherein the male component is locked into place with respect to the female component by at least one screw inserted through the at least one hole of the second plate component to form a corrective construct.   
     
     
         15 . The dynamic plate of  claim 14 , wherein the male component comprises teeth for engaging with the female component, wherein the teeth function as a gear rack. 
     
     
         16 . The dynamic plate of  claim 14 , wherein the female component comprises serrations to increase resistance with respect to movement of the male component within the female component. 
     
     
         17 . The dynamic plate of  claim 14 , wherein the first plate component further comprises:
 a base portion, the male component coupled to the base portion with at least one screw.   
     
     
         18 . The dynamic plate of  claim 14 , wherein the male component is coupled to the female component. 
     
     
         19 .
