A shoulder joint luxation in dogs, also known as a dislocated shoulder, is an injury in which the head of the humerusThe humerus is the upper arm bone that connects the shoulder joint to the elbow joint. It is an essential component of the human skeleton and supports movement and the transmission of force from the arm to the rest of the body. (humeral head) slips out of or is completely pushed out of the glenoid cavity of the scapula (glenoid).

The most important facts at a glance

A shoulder joint luxation in dogs occurs when the humeral head is forced out of the glenoid cavity of the scapula. This often occurs due to traumatic injuries such as falls or collisions. Some dog breeds, such as the Labrador Retriever or Border Collie, have a genetic predispositionA predisposition is an innate inclination or susceptibility of an organism to certain diseases or conditions.

Causes

A dog’s shoulder joint is a complex ball-and-socket joint that allows mobility in multipleMultiple means manifold or repeated and is used to describe conditions or events that occur in multiple instances or at different locations. In veterinary medicine, this may indicate multiple lesions, tumors, or other pathological changes. directions. It consists of the humeral head, which fits into the shallow glenoid cavity of the scapula. This joint is stabilized by ligaments, tendons, and muscles that work together to control movement and ensure stability.

The most common causes of shoulder joint luxation are traumatic injuries, often caused by accidents such as falls, collisions, or very strong pulling on the leash. This can lead to a sudden and excessive force that destabilizes the joint and pushes the humeral head out of the glenoid cavity.

There is also a genetic predispositionA predisposition is an innate inclination or susceptibility of an organism to certain diseases or conditions. In dogs and cats, there may be a genetic predisposition to certain conditions such as hip dysplasia or certain heart diseases. in certain dog breeds that can lead to congenitalCongenital means "present from birth" and refers to characteristics or conditions that are already present at birth. This can include genetic disorders, developmental anomalies, or infections transmitted by the mother. (inherited) instability of the shoulder joint. Breeds such as the Labrador Retriever or Border Collie are more commonly affected. This hereditary weakness can cause the joint to luxate even with minimal 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..

Symptoms

Very common symptoms:

Dogs with a shoulder luxation typically show a sudden Lameness of the affected forelimb. The dog may not be able to put weight on the leg and shows clear signs of Pain when the joint is moved or when pressure is applied to it.

Other symptoms may include Swelling in the area of the shoulder joint, an abnormal position of the leg, and a limited range of motion of the joint. In some cases, a visible deformityA deformity is an abnormal shape or structure of a body part, often due to genetic factors, injuries, or diseases. Deformities can impair function and may require cosmetic or medical treatment. can be detected, especially if the humeral head protrudes forward or to the side of the joint.

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 shoulder luxation is based on a combination of clinical examination and imaging procedures. The veterinarian will first take the dog’s historyThe medical history is the systematic collection of a patient's medical history through questioning. It includes information about previous illnesses, treatments, allergies, and lifestyle habits. and perform a physical examination to assess the mobility and stability of the joint and to localize pain.

To confirm 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., an X-rayX-ray is an imaging technique that uses X-rays to create images of the inside of the body. It is often used to diagnose bone fractures, lung diseases, and other conditions. is usually taken, which makes the position of the humeral head and any accompanying injuries visible. In some cases, an ultrasoundUltrasound refers to sound waves that are above the hearing threshold of the human ear. In medicine, ultrasound is used for diagnostic imaging procedures to visualize internal organs, tissues, and blood flow. or magnetic resonance imaging (MRI)Magnetic resonance imaging is an imaging technique that uses strong magnetic fields and radio waves to create detailed images of the inside of the body. It is used in veterinary medicine to diagnose diseases of the brain, spine, and other organs. may also be performed to assess the soft tissue structures and the exact alignment of the joint.

Therapy

The treatment of a shoulder luxation depends on the severity of the injury and the cause. In the case of an acuteAcute refers to a condition that occurs suddenly and is usually of short duration. In a medical context, it describes symptoms or illnesses that can quickly become serious and require immediate attention. luxation without accompanying fractures, the veterinarian may attempt to manually reposition the joint, which means putting the humeral head back into the glenoid cavity. This is usually done under sedationSedation refers to the state of calming or suppressing the central nervous system with medication, which reduces anxiety and irritability and sometimes induces a light sleep. or anesthesiaAnesthesia refers to the state of insensitivity to pain and can be partial (local anesthesia) or for the entire body (general anesthesia). It is used to keep patients pain-free during surgical procedures. to avoid pain.

After repositioning, the joint is usually stabilized with a bandage or splint to support healing and prevent re-luxation. In severe or chronicChronic refers to a condition or disease that is long-lasting or permanent. Chronic diseases often develop slowly and can lead to persistent or recurring health problems over time. cases, especially with repeated luxations or congenitalCongenital means "present from birth" and refers to characteristics or conditions that are already present at birth. This can include genetic disorders, developmental anomalies, or infections transmitted by the mother. instability, surgery may be required to permanently improve the stability of the joint.

Surgical options include reconstruction of the ligaments, the use of implants to stabilize the joint, or performing an arthrodesis, in which the joint is permanently stiffened to relieve pain and ensure stability.

Prognosis and follow-up care

The prognosis for dogs with a shoulder luxation varies depending on the cause of the luxation, the severity of the injury, and the treatment method chosen. With successful repositioning and stabilizing measures, the 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. is generally good, and many dogs recover completely.

Prevention

The preventionPrevention includes measures taken to prevent diseases or injuries. In veterinary medicine, this includes vaccinations, parasite control, and health monitoring. of shoulder luxation in dogs focuses on minimizing risk factors and promoting good joint health. This includes keeping the dog away from dangerous situations, such as areas where it could fall or collide with other dogs.

Regular exercise and a healthy body weight are crucial to strengthen the muscles and stabilize the joint. In breeds with a genetic predispositionA predisposition is an innate inclination or susceptibility of an organism to certain diseases or conditions. In dogs and cats, there may be a genetic predisposition to certain conditions such as hip dysplasia or certain heart diseases., controlled breeding should be ensured to minimize the spread of these genetic weaknesses.

Regular veterinary check-ups can help detect signs of instability early, and early intervention can reduce the risk of more serious injuries. In some cases, special joint supplements or diets may be recommended to support joint health.
