We perform many types of orthopedic (bone) surgeries in our clinic. Leg fractures are the most common orthopedic problem presented at our clinic and usually result from a mishap with an automobile. They can be treated in a variety of ways depending on the location and type of fracture. We can apply a cast to treat certain fractures; however, many fractures will require surgical intervention:
Fracture of bone
“Pinning” stabilizes the fracture by inserting a long stainless steel rod into the middle of the bone across the fractured area.
“Plating” involves attaching a flat stainless steel plate to the bone using screws on either side of the fracture.
“External fixation” stabilizes fractures using a series of pins on the outside of the leg that pass through the skin and into the bone on either side of the fracture.
Cruciate Ligament Rupture
There are two cruciate ligaments in a dog’s knee joint. The ligaments connect the femur (thigh bone) to the tibia (shin bone). This stabilizes the knee joint. The ligament can rupture completely (complete cruciate tear) or partially (partial cruciate tear.) The complete tear is also called an ACL or CCL tear, A ruptured cruciate is a painful and immobilizing injury. In partial rupture, the condition can be managed medically. But in complete rupture it is managed surgically.
Extracapsular Repair technique
In this method, a strong suture is placed to secure the femur and tibia, essentially replacing the function of the torn cruciate ligament. The suture supports the knee joint while scar tissue builds up and the muscles surrounding the knee strengthen.1
Luxation of patella in dog
The patella, or ‘kneecap,’ is normally located in a groove on the end of the femur (thigh bone) just above the stifle (knee).In luxating patella is a kneecap that moves out of its normal location. Pet owners may notice a skip in their dog’s step or see their dog run on three legs. Then suddenly they will be back on all four legs as if nothing happened. It can be corrected by trochelar sulcopaty and tibial tuberosity transposition in severe cases.
Trochlear sulcoplasty is a surgical technique, in which the troclear groove in the femur(Thigh bone ) is deepened to prevent slipping of the patella .
Tibial tuberosity transposition is a corrective surgery to secure the patellar tendon into the trochlear groove.Tibial tuberosity transposition uses metal implants to transplant a bone fragment to secure the tendons and ligaments in place.
Angular Limb Deformity( Leg bending in dogs)
An angular deformity refers to any condition in which a limb is not straight (excluding fractures). Deformities are typically found in forelimbs and are due to abnormal bone growth or development.
It develops secondary to unequal growth between the two bones in the lower forelimb (radius/ulna). This usually arises secondary to a growth plate (regions near the ends and tops of bones responsible for bone growth) injury. When one bone stops growing and the other keeps growing at a normal pace, the abnormal bone (usually the ulna) acts as a tension band causing the growing bone to bow, curve, and/or rotate.
It is used younger patients with significant growth potential remaining. This procedure involves cutting the ulna to release its hold on the radius. This allows the radius to straighten and grow to a normal length.
In older patients where the bone growth was completed, corrective osteotomy is performed and the bending of legs will be corrected.
