A hip luxation in dogs is an injury in which the head of the femurFemur is the technical term for the thigh bone. It connects the hip joint to the knee joint and plays a central role in supporting body weight and movement. has slipped out of the acetabulum. This leads to instability of the hip joint and can cause significant pain and limited mobility.
The most important facts at a glance
Hip luxation in dogs occurs when the femoral headThe femoral head is the ball-shaped upper part of the femur that fits into the acetabulum of the pelvis to form the hip joint. pops out of the acetabulum, often caused by traumaA trauma refers to a physical injury or damage caused by external force. Traumas can range from simple cuts to severe multiple injuries. such as car accidents or falls. The hip joint is a ball-and-socket joint that is normally stabilized by ligaments and muscles. Genetic factors, such as hip dysplasiaDysplasia is an abnormal development or growth of cells, tissues, or organs. It can be a precursor to cancer, but does not necessarily lead to cancer. Dysplasia can occur in various parts of the body, including the cervix and hip., can increase the risk. Symptoms include pain, not bearing weight on the affected leg, shortened or twisted leg. DiagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. is made by clinical examination and X-rays showing the exact position of the femoral headThe femoral head is the ball-shaped upper part of the femur that fits into the acetabulum of the pelvis to form the hip joint.. In some cases, advanced imaging is required.
Treatment can be non-surgical by repositioning the femoral headThe femoral head is the ball-shaped upper part of the femur that fits into the acetabulum of the pelvis to form the hip joint. or surgical by procedures such as femoral head resectionA femoral head resection is a surgical procedure in which the femoral head is removed.

A balanced diet and exercise are crucial for joint health. In genetically predisposed breeds, breeders should choose healthy parents and owners should consider genetic testing.
Causes
The hip joint is a ball-and-socket joint formed by the femoral headThe femoral head is the ball-shaped upper part of the femur that fits into the acetabulum of the pelvis to form the hip joint. and the acetabulum. It is stabilized by strong ligaments and the surrounding musculature. This structure allows a great range of motion, but is also susceptible to luxations if the stabilizing elements are overstressed or injured.
A common cause of hip luxation is traumaA trauma refers to a physical injury or damage caused by external force. Traumas can range from simple cuts to severe multiple injuries., such as occurs in car accidents, falls, or other severe injuries. Such traumaA trauma refers to a physical injury or damage caused by external force. Traumas can range from simple cuts to severe multiple injuries. can overstretch or tear the ligaments or joint capsules, causing the femoral headThe femoral head is the ball-shaped upper part of the femur that fits into the acetabulum of the pelvis to form the hip joint. to pop out of the socket.
In addition, certain genetic factors can increase the risk of hip luxations. Dogs suffering from hip dysplasia have a higher risk of luxation because their hip joints are already more unstable. Some breeds are also more susceptible due to their anatomyAnatomy is the scientific study of the structure of living things. It deals with the construction and organization of organisms, including their systems, organs, and tissues. and genetic predispositions.
Other causes can be degenerative changes in the joint or poor muscle tone that does not provide enough stability. Inadequate nutrition or disease leading to muscle weakness can also be a contributing factor.
Symptoms
Dogs with a hip luxation often show a sudden lameness in the affected hind leg. This occurs immediately after the injury and may be accompanied by visible pain.
Affected dogs often show a noticeable limp or avoid putting weight on the affected leg. In some cases, the leg may be held in an unnatural position, indicating displacement of the joint.
Other signs may include swelling, tenderness to the touch, and a visible change in the hip contour. The dog may also show signs of stressStress refers to the state of an organism reacting to external stimuli or demands. In veterinary medicine, stress can have physical or psychological effects on animals, impacting their health and well-being. or discomfort, such as panting or whining.
Diagnosis
The diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. of a hip luxation is usually made through a thorough clinical examination and an X-ray of the affected area. During the examination, the veterinarian will check the mobility of the hip joint and look for signs of pain or instability.
X-rays are crucial to determine the exact position of the femoral headThe femoral head is the ball-shaped upper part of the femur that fits into the acetabulum of the pelvis to form the hip joint. in relation to the acetabulum. They also help to rule out other possible injuries or conditions that could be causing the symptoms.
In some cases, advanced imaging such as a CT scan may be required to obtain a more detailed view of the joint structures, especially if the X-rays are not clear or complex injuries are suspected.
Therapy
The treatment of a hip luxation depends on the severity of the injury and the dog’s general health. A non-surgical reduction of the femoral headThe femoral head is the ball-shaped upper part of the femur that fits into the acetabulum of the pelvis to form the hip joint. back into the acetabulum may be attempted in some cases, especially if the luxation has occurred recently and there are no other injuries.
After the reduction, the dog may be kept in a special bandage or sling for a few weeks to stabilize the hip while the ligaments and muscles heal. Rest and restricted movement are crucial during this time.
In more severe cases, or if non-surgical treatment is unsuccessful, surgery may be required. Surgical options include femoral headThe femoral head is the ball-shaped upper part of the femur that fits into the acetabulum of the pelvis to form the hip joint. ostectomy (removal of the femoral headThe femoral head is the ball-shaped upper part of the femur that fits into the acetabulum of the pelvis to form the hip joint.) or total hip replacement surgery.
Aftercare typically includes physiotherapyVeterinary physiotherapy encompasses a range of treatment methods aimed at improving the mobility and well-being of animals through exercise, massage, and other manual techniques. to strengthen the muscles and improve joint mobility. Pain relievers and anti-inflammatory medications may also be administered to support the healing process.
Prognosis and follow-up care
The prognosis for dogs with a hip luxation depends on several factors, including the promptness of treatment and the severity of the injury. Early diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. and treatment significantly improve the chances of a full recovery.
Dogs who receive successful non-surgical reduction or surgical correction often have a good to excellent prognosisThe prognosis is the prediction of the likely course and outcome of a disease based on the general state of health, the nature of the disease, and the response to treatment. It can provide information on how a disease is expected to develop.. A full restoration of normal joint function is possible, especially if aftercare is carefully performed.
In cases where the condition remains untreated or treatment is delayed, permanent joint instability or osteoarthritis may occur, which can impair the dog’s quality of life.
Prevention
The preventionPrevention includes measures taken to prevent diseases or injuries. In veterinary medicine, this includes vaccinations, parasite control, and health monitoring. of hip luxations includes measures to minimize the risk of injury. These include ensuring a safe environment where the dog cannot easily fall or be injured, as well as avoiding excessive physical stressStress refers to the state of an organism reacting to external stimuli or demands. In veterinary medicine, stress can have physical or psychological effects on animals, impacting their health and well-being..
Regular veterinary examinations are important to detect early signs of hip dysplasiaDysplasia is an abnormal development or growth of cells, tissues, or organs. It can be a precursor to cancer, but does not necessarily lead to cancer. Dysplasia can occur in various parts of the body, including the cervix and hip. or other joint problems. A balanced diet and regular exercise also contribute to maintaining muscle strength and joint health.
For breeds that are genetically predisposed, special precautions may be necessary. Breeders should pay attention to selecting healthy parents, and owners may consider genetic testing to assess the risk.
Early treatment of injuries and degenerative diseases can also help reduce the risk of hip luxation by maintaining the stability and health of the joint.
