![]() ![]() ![]() Metatarsal stress fractures occur as the result of repetitive load applied to the bone in an amount or at a rate that is greater than the ability of the bone to repair itself. The radiographic classification that we have proposed is intended to aid surgeons treating and discussing fractures localized to the distal portion of the fifth metatarsal.ĭiagnosis diaphysis injury radiograph tent sign trauma. Summary Metatarsal fractures present in two basic categories: stress fractures and traumatic fractures. To our knowledge, a classification system for fractures of the distal shaft of the fifth metatarsal has not been previously reported. A dancers fracture is a spiral or oblique fracture of the distal shaft or neck of the fifth metatarsal, resulting from inversion of the foot from a. Proximal fifth metatarsal fractures that are distal to the tuberosity have a. If the flexion deformity exceeds 10-20 degrees in fractures of the second and third metacarpals, or 20-30 degrees in. Most of these fractures produce a flexion deformity and often minimal shortening. Grade I and III fractures accounted for 29% and 22% of the distal fifth metatarsal fractures, respectively. Avulsion fractures of the proximal fifth metatarsal tuberosity can usually be managed with a soft dressing. Undisplaced, or minimally displaced, fractures of the metacarpal shaft can be treated nonoperatively. The classification system is based on a review of 79 spiral oblique fractures of the distal shaft of the fifth metatarsal. Grade II fractures were most prevalent and accounted for 49% of the cases reviewed. In the present report, a new radiographic classification for distal shaft fractures of the fifth metatarsal is presented. Four distinct fracture configurations emerged as a result of our radiographic analysis, and these were categorized as grades I, IIA, IIB, and III. Types acute, intra-articular fracture at the junction of the metaphysis and diaphysis of the fifth metatarsal extends into the intermetatarsal joint between. A prospective nonrandomized study was made of 17 basketball players with fractures of the proximal third of the shaft of the fifth metatarsal. The sample was grouped into "grades" of deformity according to the configuration of the fracture and the amount of displacement observed for each injury. This is the long bone on the outside of the foot that connects to the smallest toe. The classification system is based on a review of 79 spiral oblique fractures of the distal shaft of the fifth metatarsal. A Jones fracture is a break in a bone on the outside of the foot, in the fifth metatarsal. In the present report, a new radiographic classification for distal shaft fractures of the fifth metatarsal is presented. ![]()
