Abstract
A mongrel dog aged 2, weighing 10 kg, with multiple pelvic fractures, associated with fracturedislocation of the right-hind hip joint, was treated using internal fixation with U/T compression and a modified self-compression plate. The modified plate was remodelled from a 4-holed self-compression plate by making 6 cuneiform cuts between its holes. Excellent surgical reduction of the hip joint was able to be achieved by using a plate which was contoured in three planes to fit the dorsal curves of the iliac bone and ischium, as well as contoured cranially and caudally to fit the acetabulum. There was no deformation of the screw holes due to bending the modified plate at an angle of about 45° between two adjacent screw holes. The stability of the hip-bone and joint was achieved not only by the reduction of the joint but also by stabilization of the right hind iliac body. The function of the right hind leg gradually recovered, and about 5 months postoperatively, complete recoveryof movement was achieved. The modified plate appears to offer versatility in the treatment of multiple pelvic fractures with acetabular comminution.
