FNA and surgery is often not recommended, these can introduce infection and the hygroma will return larger. Donut bandage and soft bedding are key to treating. In the past it was common for veterinarians to treat hygromas by aspiration (using a syringe and drawing the fluid out) or surgically placing a drain. This can address the symptom, but does not treat the cause of the hygroma. In addition any incision at a joint can be difficult to close and may result in an open sore. Consequently, the recommended treatment of choice for most hygromas is no longer aspiration or surgery, but commercially available elbow pads made for the treatment of this condition.

There are solutions available to cover and protect the elbow joint.

Baker's cysts usually require no treatment unless they are symptomatic. It is very rare that the symptoms are actually coming from the cyst. In most cases, there is another disorder in the knee (arthritis, meniscal (cartilage) tear, etc.) that is causing the problem. Initial treatment should be directed at correcting the source of the increased fluid production. Often rest and leg elevation are all that is needed. If necessary, the cyst can be aspirated to reduce its size, then injected with a corticosteroid to reduce inflammation. Surgical excision is reserved for cysts that cause a great amount of discomfort to the patient. A ruptured cyst is treated with rest, leg elevation, and injection of a corticosteroid into the knee.

Baker's cysts in children, unlike in older people, nearly always disappear with time, and rarely require excision.

Ice pack therapy may sometimes be an effective way of controlling the pain related to Baker's cyst. Heat is also commonly used. A knee brace can offer support giving the feel of stability in the joint.

Rest and specific exercise

Many activities can put strain on the knee, and cause pain in the case of Baker's cyst. Avoiding activities such as squatting, kneeling, heavy lifting, climbing, and even running can help prevent pain. Despite this, some exercises can help relieve pain, and a physiotherapist may instruct on stretching and strengthening the quadriceps and/or the patellar ligament.

Osteochondromas are benign lesions and do not affect life expectancy. Complete excision of osteochondroma is curative and the reoccurrences take place when the removal of tumor is incomplete. Multiple reoccurrences in a well-excised lesion indicate that it may be malignant. The risk of malignant transformation takes place in 1–5% of individuals. If any symptoms of cancerous tumor takes place, then the patient should be evaluated by a bone specialist. No treatment is necessary for Solitary osteochondromas that are asymptomatic. Treatments for solitary osteochondroma are careful observation over time and taking regular x-rays to monitor any changes in the tumor. If the lesion is causing pain with activity, nerve or vessel impingement, or if the bone growth has fully matured and the presence of a large cartilage cap is prominent, then it is advised that the tumor be surgically removed.

Osteochondromas have a low rate of malignancy (<1%) and resection of the tumor is suggested if symptoms such as pain, limitation of movement, or impingement on nerves or vessels occur. Resection of the tumor also takes place when the tumor increases in size and progresses towards malignancy. During surgical resection, the entire lesion along with the cartilaginous cap should be removed to minimize any chances of reoccurrences. Surgical treatment becomes the sole treatment of choice if common complications such as fractures, symptoms of peripheral nerves such as paresthesia, paraplegia, peroneal neuropathy, and upper limb neuropathy take place. A prophylactic resection is suggested if the lesion lies next to a vessel.

Depending on the size and location of the tumor, the time it takes to return to normal daily activities varies between individuals. Limitation on some activities is advised if pain or discomfort persists after surgical excision.

Endotoxemia is a serious complication of colic and warrants aggressive treatment. Endotoxin (lipopolysaccharide) is released from the cell wall of gram-negative bacteria when they die. Normally, endotoxin is prevented from entering systemic circulation by the barrier function of the intestinal mucosa, antibodies and enzymes which bind and neutralize it and, for the small amount that manages to enter the blood stream, removal by Kupffer cells in the liver. Endotoxemia occurs when there is an overgrowth and secondary die-off of gram negative bacteria, releasing mass quantities of endotoxin. This is especially common when the mucosal barrier is damaged, as with ischemia of the GI tract secondary to a strangulating lesion or displacement. Endotoxemia produces systemic effects such as cardiovascular shock, insulin resistance, and coagulation abnormalities.

Fluid support is essential to maintain blood pressure, often with the help of colloids or hypertonic saline. NSAIDs are commonly given to reduce systemic inflammation. However, they decrease the levels of certain prostaglandins that normally promote healing of the intestinal mucosa, which subsequently increases the amount of endotoxin absorbed. To counteract this, NSAIDs are sometimes administered with a lidocaine drip, which appears to reduce this particular negative effect. Flunixin may be used for this purpose at a dose lower than that used for analgesia, so can be safely given to a colicky horse without risking masking signs that the horse requires surgery. Other drugs that bind endotoxin, such as polymyxin B and Bio-Sponge, are also often used. Polymixin B prevents endotoxin from binding to inflammatory cells, but is potentially nephrotoxic, so should be used with caution in horses with azotemia, especially neonatal foals. Plasma may also be given with the intent of neutralizing endotoxin.

Laminitis is a major concern in horses suffering from endotoxemia. Ideally, prophylactic treatment should be provided to endotoxic horses, which includes the use of NSAIDs, DMSO, icing of the feet, and frog support. Horses are also sometimes administered heparin, which is thought to reduce the risk of laminitis by decreasing blood coagulability and thus blood clot formation in the capillaries of the foot.

In addition to fluid support, impactions are often treated with intestinal lubricants and laxatives to help move the obstruction along. Mineral oil is the most commonly used lubricant for large colon impactions, and is administered via nasogastric tube, up to 4 liters once or twice daily. It helps coat the intestine, but is not very effective for severe impactions or sand colic since it may simply bypass the obstruction. Mineral oil has the added benefit of crudely measuring GI transit time, a process which normally takes around 18 hours, since it is obvious when it is passed. The detergent dioctyl sodium sulfosuccinate (DDS) is also commonly given in oral fluids. It is more effective in softening an impaction than mineral oil, and helps stimulate intestinal motility, but can inhibit fluid absorption from the intestine and is potentially toxic so is only given in small amounts, two separate times 48 hours apart. Epsom salts are also useful for impactions, since they act both as an osmotic agent, to increase fluid in the GI tract, and as a laxative, but do run the risk of dehydration and diarrhea. Strong laxatives are not recommended for treating impactions.

The primary treatment is rest. This does not mean bed rest or immobilizing the area but avoiding actions which result in aggravation of the pain. Icing the joint may help. A non-steroidal anti-inflammatory drug may relieve pain and reduce the inflammation. If these are ineffective, the definitive treatment is steroid injection into the inflamed area.

Physical therapy to strengthen the hip muscles and stretch the iliotibial band can relieve tension in the hip and reduce friction. The use of point ultrasound may be helpful, and is undergoing clinical trials.

In extreme cases, where the pain does not improve after physical therapy, cortisone shots, and anti-inflammatory medication, the inflamed bursa can be removed surgically. The procedure is known as a bursectomy. Tears in the muscles may also be repaired, and loose material from arthritic degeneration of the hip removed. (At the time of bursal surgery, a very close examination of the gluteal tendons will reveal sometimes subtle and sometimes very obvious degeneration and detachment of the gluteal tendons. If this detachment is not repaired, removal of the bursa alone will make little or no difference to the symptoms.)

The bursa is not required, so the main potential complication is potential reaction to anaesthetic. The surgery can be performed arthroscopically and, consequently, on an outpatient basis. Patients often have to use crutches for a few days following surgery up to a few weeks for more involved procedures.

There are numerous case reports in which surgery has relieved GTPS, but its effectiveness is not documented in clinical trials.

Vasodilators improve the blood flow into the vessels of the hoof. Examples include isoxsuprine (currently unavailable in the UK) and pentoxifylline.

Anticoagulants can also improve blood flow. The use of warfarin has been proposed, but the extensive monitoring required makes it unsuitable in most cases.

Anti-inflammatory drugs are used to treat the pain, and can help the lameness resolve sometimes if shoeing and training changes are made. Include Nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, and other joint medications. The use of intramuscular glycosaminoglycans has been shown to decrease pain in horses with navicular disease, but this effect wanes after discontinuation of therapy. Oral glycosaminoglycans may have a similar effect.

Bisphosphonates can be useful in cases where bone remodeling is causing pain.

Gallium nitrate (GaN) has been hypothesized as a possible treatment for navicular disease, but its benefits have not been confirmed by formal clinical studies. One pilot study examined horses given gallium nitrate in their feed rations. While it was absorbed slowly, it did stay in the animals' system, providing a baseline dosage for future studies.

Conservative management of minor cases involves icing, a firm compression bandage, and avoidance of the aggravating activity. This can also be augmented with oral or topical anti-inflammatory medications such as NSAIDs. Elbow padding can also be used for symptomatic relief. Treatment for more severe cases may include the excess bursa fluid with a syringe (draining of the bursa), or injecting into the bursa a hydrocortisone type medication which is aimed at relieving the inflammation and preventing further accumulation of fluid.

In case of infection, the bursitis should be treated with an antibiotic.

Conservative treatment for bunions include changes in footwear, the use of orthotics (accommodative padding and shielding), rest, ice, and pain medications such as acetaminophen or nonsteroidal anti-inflammatory drugs. These treatments address symptoms but do not correct the actual deformity. If the discomfort persists and is severe or when aesthetic correction of the deformity is desired, surgical correction by an orthopedic surgeon or a podiatric surgeon may be necessary.

Orthotics are splints or regulators while conservative measures include various footwear like gelled toe spacers, bunion/toe separators, bunion regulators, bunion splints, and bunion cushions. There are a variety of available orthotics (or orthoses) including over-the-counter or off-the-shelf commercial products and as necessary, custom-molded orthotics that are generally prescribed medical devices.

If the fluid continues to return after multiple drainings or the bursa is constantly causing pain to the patient, surgery to remove the bursa is an option. The minor operation removes the bursa from the elbow and is left to regrow but at a normal size over a period of ten to fourteen days. It is usually done under general anesthetic and has minimal risks. The surgery does not disturb any muscle, ligament, or joint structures. To recover from surgical removal, a splint will be applied to the arm to protect the skin. Exercises will be prescribed to improve range of motion.

Since there is a variety of classifications of winged scapula, there is also more than one type of treatment. Massage Therapy is an effective initial approach to relax the damaged muscles. In more severe cases, Physical Therapy can help by strengthening affected and surrounding muscles. Physical therapy constitutes treatment options if there is weakness of the glenohumeral joint muscles, but if the muscles do not contract clinically and symptoms continue to be severe for more than 3–6 months, surgery may be the next choice. Surgery by fixation of the scapula to the rib cage can be done for those with isolated scapular winging. Some options are neurolysis (chordotomy), intercostal nerve transfer, scapulothoracic fusion, arthrodesis (scapulodesis), or scapulothoracis fixation without arthrodesis (scapulopexy).

Vaccination is the only known method to prevent the development of tumors when chickens are infected with the virus. However, administration of vaccines does not prevent transmission of the virus, i.e., the vaccine is not sterilizing. However, it does reduce the amount of virus shed in the dander, hence reduces horizontal spread of the disease. Marek's disease does not spread vertically. The vaccine was introduced in 1970 and the scientist credited with its development is Dr. Ben Roy Burmester and Dr. Frank J Siccardi. Before that, Marek's disease caused substantial revenue loss in the poultry industries of the United States and the United Kingdom. The vaccine can be administered to one-day-old chicks through subcutaneous inoculation or by "in ovo" vaccination when the eggs are transferred from the incubator to the hatcher. "In ovo" vaccination is the preferred method, as it does not require handling of the chicks and can be done rapidly by automated methods. Immunity develops within two weeks.

The vaccine originally contained the antigenically similar turkey herpesvirus, which is serotype 3 of MDV. However, because vaccination does not prevent infection with the virus, the Marek's disease virus has evolved increased virulence and resistance to this vaccine. As a result, current vaccines use a combination of vaccines consisting of HVT and gallid herpesvirus type 3 or an attenuated MDV strain, CVI988-Rispens (ATCvet code: ).

Palmar digital neurectomy (or "nerving" or "denerving") is not without adverse side effects and should therefore be used as a last resort. In this procedure, the palmar digital nerves are severed, so the horse loses sensation in the back of the foot. This procedure should only be performed if it will eliminate the lameness associated with navicular syndrome, and only after all other options have been explored. The procedure is usually performed on both front feet. Complications can include infection of the wound, continuation of the lameness (if the nerves regrow or if small branches of the nerves are not removed), neuromas, and rupture of the deep digital flexor tendon. After the neurectomy, if the horse becomes injured in the area the injury may go undetected for a long period of time, which risks the animal's health. Due to this, the feet should be cleaned and inspected regularly. Neurectomy tends to lower the market value of a horse, and may even make the horse ineligible for competition. Neurectomy is controversial. The most common misconception about "nerving" a horse is that it will permanently solve the lameness/pain issue. In fact, though the time periods vary based on the individual horse and surgical method utilized, these nerves often regenerate and return sensation to the afflicted region within two to three years.

In navicular suspensory desmotomy, the ligaments supporting the navicular bone are severed. This makes the navicular bone more mobile, and thus reduces the tension of the other ligaments. It is successful about half of the time.

There is currently no specific treatment for the virus. A vaccine is available, but only experimentally. It has not been released to the public due to the risk it poses to already exposed birds.

Therapeutic intervention is limited to treating secondary infections. The individual bird can sometimes recover, but this is rare. If only the feathers are affected and the bird suffers no other symptoms, it can usually experience an acceptable quality of life. But if the bird's beak or nails are affected, veterinarians will recommend euthanasia.

The management of the disease lies thus mostly in prevention. Every new bird that enters a pen with other birds should be quarantined first and be tested for BFDV. Birds which are known carriers should not be introduced into new pens, especially not if those contain young birds.

Currently, no therapeutic drugs are prescribed for the disease. Therefore, prevention is the sole mode of treatment. This disease can only be prevented by quarantining sick birds and preventing migration of birds around the house, causing them to spread the disease. Deworming of birds with anthelmintics can reduce exposure to the cecal nematodes that carry the protozoan. Good management of the farm, including immediate quarantine of infected birds and sanitation, is the main useful strategy for controlling the spread of the parasitic contamination. The only drug used for the control (prophylaxis) in the United States is nitarsone at 0.01875% of feed until 5 days before marketing. Natustat and nitarsone were shown to be effective therapeutic drugs. Nifurtimox, a compound with known antiprotozoal activity, was demonstrated to be significantly effective at 300–400 ppm, and well tolerated by turkeys.

Anti-helminthics are often used to kill off the worms, however in some cases this may cause patients to worsen due to toxins released by the dying worms. Albendazole, ivermectin, mebendazole, and pyrantel are all commonly used, though albendazole is usually the drug of choice. Studies have shown that anti-helminthic drugs may shorten the course of the disease and relieve symptoms. Therefore anti-helminthics are generally recommended, but should be administered gradually so as to limit the inflammatory reaction.

A Baker's cyst, also known as a popliteal cyst, is a benign swelling of the semimembranosus or more rarely some other synovial bursa found behind the knee joint. It is named after the surgeon who first described it, William Morrant Baker (1838–1896). It is not a "true" cyst, as an open communication with the synovial sac is often maintained.

Limited normal functions and movements are caused by osteochondromas growing slowly and inwardly. The majority of osteochondromas are symptomless and are found incidentally. Each individual with osteochondroma may experience symptoms differently and most of the time individuals will experience no symptoms at all. Some of the most common symptoms are a hard immobile painless palpable mass, adjacent muscle soreness, and pressure or irritation with heavy exercising.

Major symptoms arise when complications such as fractures, bone deformity or mechanical joint problems occur. If the occurrence of an osteochondroma is near a nerve or a blood vessel, the affected limb can experience numbness, weakness, loss of pulse or color change. Periodic changes in the blood flow can also take place. Approximately 20% of patients experiencing nerve compression commonly acknowledge vascular compression, arterial thrombosis, aneurysm, and pseudoaneurysm. Formation of pseudoaneurysm and venous thrombosis lead to claudication, pain, acute ischemia, and symptoms of phlebitis. If the tumor is found under a tendon, it can cause pain during movement causing restriction of joint motion. Pain can also occur due to bursal inflammation, swelling or fracture at the base of the tumor stalk. Some of the clinical signs and symptoms of malignant osteochondroma are pain, swelling, and mass enlargement.

Treatment of angiostrongyliasis is not well defined, but most strategies include a combination of anti - parasitics to kill the worms, steroids to limit inflammation as the worms die, and pain medication to manage the symptoms of meningitis.

Because wear on the hip joint traces to the structures that support it (the posture of the legs, and ultimately, the feet), proper fitting shoes with adequate support are important to preventing GTPS. For someone who has flat feet, wearing proper orthotic inserts and replacing them as often as recommended are also important preventive measures.

Strength in the core and legs is also important to posture, so physical training also helps to prevent GTPS. But it is equally important to avoid exercises that damage the hip.

This method should be used within the first 48–72 hours after the injury in order to speed up the recovery process.

Heat: Applying heat to the injured area can cause blood flow and swelling to increase.

Alcohol: Alcohol can inhibit your ability to feel if your injury is becoming more aggravated, as well as increase blood flow and swelling.

Re-injury: Avoid any activities that could aggravate the injury and cause further damage.

Massage: Massaging an injured area can promote blood flow and swelling, and ultimately do more damage if done too early.

Treatment of fluid in the knee depends on the underlying cause of the swelling. General measures such as rest, ice, and analgesics such as acetaminophen (paracetamol) and NSAIDS are often recommended. Chymotrypsin, trypsin and Diclofenac are also recommended.

Non-septic prepatellar bursitis can be treated with rest, the application of ice to the affected area, and anti-inflammatory drugs, particularly ibuprofen. Elevation of the affected leg during rest may also expedite the recovery process. Severe cases may require fine-needle aspiration of the bursa fluid, sometimes coupled with cortisone injections. However, some studies have shown that steroid injections may not be an effective treatment option. After the bursitis has been treated, rehabilitative exercise may help improve joint mechanics and reduce chronic pain.

Opinions vary as to which treatment options are most effective for septic prepatellar bursitis. McAfee and Smith recommend a course of oral antibiotics, usually oxacillin sodium or cephradine, and assert that surgery and drainage are unnecessary. Wilson-MacDonald argues that oral antibiotics are "inadequate", and recommends intravenous antibiotics for managing the infection. Some authors suggest surgical irrigation of the bursa by means of a subcutaneous tube. Others suggest that bursectomy may be necessary for intractable cases; the operation is an outpatient procedure that can be performed in less than half an hour.
