RESUMO
Intramedullary nail fixation is an excellent option for open reduction and internal fixation of metatarsal neck and shaft fractures. In the authors' experience, the reduction of these fractures with Steinmann pin fixation provided excellent stability, required minimal soft-tissue dissection, and allowed for preservation of the periosteal tissue. Minimal disruption to the periosteum protects the osteoprogenitor cells located in the cambium layer. These cells stimulate osteoblastic activity, allowing for excellent secondary bone healing. Intramedullary nail fixation is the authors' chosen procedure for reduction of lesser metatarsal fractures.

RA is a common disorder that has significant destructive effects on the midfoot portion of the foot. When these degenerative joint changes occur, any motion at the involved joints causes severe pain and disability, and limits the patient in his or her attempt to perform daily activities. These changes have a significant social and economic impact, and cause unwanted lifestyle changes. Arthrodesis, when used judiciously, can offer pain relief and a restoration of normal activity for the patient with RA.
