  • Title: Metacarpal and metatarsal fractures in dogs.
    Author: Muir P, Norris JL.
    Journal: J Small Anim Pract; 1997 Aug; 38(8):344-8. PubMed ID: 9282340.
    Abstract:
    Metacarpal fractures were more common than metatarsal fractures in this retrospective study of 37 dogs. Fractures of one metacarpal or metatarsal bone occurred in 24 per cent of the dogs, two metacarpal bones in 16 per cent, three metacarpal or metatarsal bones in 19 per cent, and four metacarpal or metatarsal bones in 41 per cent. Eighty-seven per cent of the dogs with fractures of four bones had fracture displacement or malalignment of at least one digit. Progressive fracture healing usually occurred irrespective of stabilisation method. For malaligned fractures, however, external coaptation did not consistently improve alignment. Fracture alignment was consistently improved by open reduction and internal fixation of acute fractures with bone plates. Fractures of four bones occurred most often in the distal metacarpus as opposed to the proximal metatarsus. Therefore, open reduction and internal fixation may be more commonly indicated for severe metacarpal fractures, because fracture displacement or axial malalignment was significantly associated with fractures of the mid or distal regions of the metacarpus or metatarsus (P = 0.052).
