【 摘 要 】

Category:Midfoot/ForefootIntroduction/Purpose:In the modern treatment of Charcot neuroarthropathy, beam screw fixation is an attractive alternative to plate and screw fixation because it minimizes the required exposure for implantation and supports the longitudinal columns of the foot from the inside out as a rigid yet load-sharing construct. Oversized implants risk metatarsal fracture and undersized implants risk implant fracture or impaired healing from mechanical instability. Our review of the scientific literature identified a lack of evidence regarding the aspects of metatarsal intramedullary canal morphology relevant to beam screw fixation. The purpose of the present study was to qualitatively and quantitatively describe metatarsal diaphyseal morphology.Methods:Twenty fresh-frozen adult cadaveric below knee specimens were utilized to assess the size and shape of the diaphysis of metatarsals 1-4. There were 10 male and 10 female specimens with a mean age of 75.8 years. No limbs had outward signs of p...
