Devices And Methods For Metatarsophalangeal Arthroplasty Procedures

Abstract

The present technology relates generally to devices and methods for arthroplasty procedures. In some embodiments, for example, a device is disclosed for use during an arthroplasty procedure of a joint of a patient, the joint extending between a first joint end of a first bone and an abutting second joint end of a second bone of the patient. The device can include an end plate configured and arranged for disposing over the first joint end of the first bone, a longitudinal plate extending from the end plate and configured and arranged for disposing along a medial, longitudinal surface of the first bone, and a stem extending from the end plate and suitable for extending along an intra-medullary canal of the first bone. When installed, at least one fastener can extend at least partially through the first bone and couples the longitudinal plate to the first bone.

1 - 14 . (canceled) 
     
     
         15 . A method of performing an arthroplasty procedure on a joint of a human patient, the joint extending between a first joint end of a first bone and an abutting second joint end of a second bone of the patient, the method comprising:
 removing a portion of the first joint end of the first bone;   coupling an implant to the first joint end of the first bone, such that
 a stem of the implant is disposed within an intra-medullary canal of the first bone; 
 an end plate of the implant is disposed over the first joint end of the first bone; and 
 a longitudinal plate of the implant is disposed along a medial, longitudinal surface of the first bone; and 
   extending a fastener between the longitudinal plate and the stem, the fastener passing
 through the longitudinal surface of the first bone. 
   
     
     
         16 . The method of  claim 15 , further comprising reaming the intra-medullary canal of the first bone prior to coupling the implant to the first joint end of the first bone. 
     
     
         17 . The method of  claim 15  wherein removing the portion of the first joint end of the first bone comprises cutting the portion of the first joint end of the first bone using a surgical template. 
     
     
         18 . The method of  claim 15  wherein the joint is a metatarsophalangeal joint, the first bone is a metatarsus bone, and the second bone is an abutting proximal phalanx bone. 
     
     
         19 . The method of  claim 15  wherein the joint is a metatarsophalangeal joint, the first bone is a proximal phalanx bone of a foot, and the second bone is an abutting metatarsal bone. 
     
     
         20 . The method of  claim 15 , further comprising:
 drilling a hole through at least a portion of the first bone prior to extending the fastener;
 and 
   passing the fastener through the hole.
