These types of deformities are most easily corrected with the use of tube casting, which allows the foot to be exposed. These casts keep the affected joints in a normal position until the soft tissue structures become stronger and can support the joint. Without cast support, the incompletely formed bones cannot bear the weight of the foal and can become crushed, which is referred to as carpal crush or tarsal crush syndrome. If the angular deformity does not correct on its own within a few weeks or is moderate to severe, then surgical therapy should be attempted. Surgery to treat these deformities involves one of two procedures.
Periosteal elevation helps stimulate growth.
The procedure is used when there is uneven growth and one side of a long bone is growing at a faster rate than the other, leading to an angular limb deformity. This is a rather simple surgical procedure, has little risk involved, and good cosmetic results. The second type of procedure is called transphyseal bridging. This involves placing screws and wires or orthopedic staples to slow growth on one side of a growth plate. This is used for moderate to severe deformities.
