Abstract
|
|
|
|
A stress fracture can be defined as a spontaneous fracture due to accumulation of stress on a healthy bone. Stress fractures of the 5th metatarsal usually locate to the proximal 1.5 cm of the metatarsal shaft, a characteristic based on anatomical and biomechanical parameters. Many surgeons agree that the postoperative outcome of 5th metatarsal stress fractures tend to be associated with prolonged healing time, with nonunion, and sometimes with refracture. Acute stress fractures have been treated with immobilization using a non-weight-bearing cast, but the incidence of complications (delayed union or nonunion) after non-surgical treatment makes surgical treatment a more favorable treatment option for competitive athletes, even for young adults. Curettage and bone grafting or intramedullary screw fixation, the standard surgical treatment for the 5th metatarsal stress fractures, has been associated with rapid recovery and early return to physical activities. Malalignment or instability of the foot or ankle must be addressed at the time of surgical treatment.
