摘要: Dual-energy x-ray absorptiometry was used to measure bone mineral density of four regions in healed femora nine dogs after fracture fixation with a leg-lengthening plate. Six 85 months (mean, 46 months) surgery, the not significantly different from contralateral uninjured (P > .05; power = 0.8 at delta 15%). Radiolucencies around proximal screws, apparently associated screw loosening, were seen on radiographic views three dogs. In one these dogs, metaphysis had broken. Force-plate analysis gait also performed time measurement. Peak vertical force decreased pelvic limb compared unoperated < 0.05). Clinically apparent lameness did appear be altered and may have been caused by hip osteoarthritis, nondisplaced hairline diaphyseal fracture, loosening conjunction extensive post-traumatic soft tissue injury.
