Unusual Navicular Bone Fractures in HindLimbs: Clinical and Imaging Findings
چکیده انگلیسی
Three horses were identified with an unusual fracture configuration of a hindlimb navicular bone. All horses had unilateral lameness which was worse on a circle on a firm surface and was abolished by plantar nerve blocks performed at the base of the proximal sesamoid bones. Radiological findings included an ill-defined curvilinear radiolucent line along the distal horizontal border of the navicular bone in case 1; cases 2 and 3 had three fragments along the distal horizontal border, associated, in case 2, with marked abnormalities extending into the spongiosa of the bone. Lesions in case 2 were bilateral despite unilateral lameness. Fractures parallel to the distal horizontal border of the navicular bone have not been described in front limbs; neither have more than two fragments been observed along the distal border. One previous report describes a lesion similar to that in case 1 in a hindlimb navicular bone. Fragmentation of the distal horizontal border associated with rupture of the distal sesamoidean impar ligament and proximal displacement of the bone has been reported in hindlimbs. It is likely that biomechanical reasons are responsible for the occurrence of these lesions in hindlimbs.
