This is an automatically translated article.

Osteoid osteoma is a benign bone tumor that is common in adolescents. The disease causes a lot of pain, especially at night, affecting the activities and general development of the sufferer.

1. Overview

1.1. Definition Osteoid osteoma is a benign bone lesion, when an area of ​​sclerosis reacts, surrounded by a very small size of about 1.5 - 2cm. The disease occurs mainly in:
The long bony trunks of the lower extremities: about 80 - 90%; Spine : accounted for 7 - 20%; In joints, skull bones: Rare. Osteosarcoma accounts for about 10% of benign tumors and 5% of primary osteosarcomas. The age of the disease is mainly under 25 (accounting for 90%), of which men are more susceptible to this disease than women.
1.2. Causes Currently, the cause of osteosarcoma is not fully understood, however genetics is believed to be one of the major factors. Some experts also think that the cause of the disease can also be viral, inflammatory, or related to the immune system. Osteoid osteoma will sometimes regress on its own in some patients after a certain period of time.
1.3. Treatment Medical or surgical treatment (surgery to remove tumor tissue) has long been applied to treat this disease. Specifically:
Medical treatment: Give patients pain relievers or non-steroidal anti-inflammatory drugs (NSAIDs), effective for a long time; Surgical treatment: Indicated for patients who do not respond to medical treatment and limit exercise much. Including open surgery, minimally invasive surgery, subcutaneous surgery with the help of CT or computer scan, tumor removal surgery with the participation of radioisotope... Important factors The most important factor for the success of surgery in general is to determine the correct tumor location. In addition, treatment of osteosarcoma by interventional radiology under the guidance of digital background erasure is a new option. This technique has the advantage of minimally invasive, and has proven to be highly effective in practice.

2. Preparation steps

2.1. The person performing the interventional radiology specialist and technician; Physician support; Nursing staff. 2.2. Means Digital background eraser (DSA circuit angiography); Film and film printers; Image storage system; Set of lead vest and apron for X-ray protection and shielding 2.3. Medications Local anesthetics; Anti-coagulation drugs; Water-soluble Iodine Contrast; Antiseptic solution for skin and mucous membranes. 2.4. General medical supplies

Syringes of sizes 3 - 5 - 10ml; Specialized injection pump electric pump; Distilled water or physiological saline; Gloves, gowns, caps and surgical masks; Aseptic intervention kit: Knife, scissors, tongs, metal bowl, pea tray and tool tray; Cotton bandages and surgical gauze. Contrast drug accident emergency box. 2.5. Special medical supplies 11G or 13G bone needles; Surgical hammer. 2.6. The patient is thoroughly explained about the technique to coordinate with the doctor; Need to fast and drink before 6 hours, can drink ≤ 50ml of water; Give a sedative if you are too excited, do not lie still... 2.7. Test sheet Medical record of inpatient bone tumor treatment; Indication sheet for performing background removal digitization procedure has been approved; X-ray film, CT Scan or MRI if available.

3. Steps to take

3.1. Anesthesia method Local anesthesia with Lidocaine 2%, dose 2 - 10ml depending on the biopsy site; Use systemic analgesics if the patient is in a lot of pain or for sensitive patients; General anesthesia for patients who are children, cannot cooperate. 3.2. Techniques Place the patient on the table to increase the light; Establish an intravenous line; Locating the site of injury; Disinfect the injured area; The doctor washes the surgical hands, puts on a shirt and gloves, and then spreads a sterile canvas with holes on the biopsy site; Local anesthetic layer by layer; Needle puncture to cut the bone according to the intended path, while controlling the puncture line under the screen; When the needle is inserted into the right lesion, proceed to cut the entire bone tumor nucleus; Withdraw the needle, collect the specimen in the needle, and fix the hormone (formol); Tape the puncture site.

4. Result

The technique is considered successful if:
The needle pokes in the right place; Removal of osteosarcoma nuclei; No complications after the procedure; Promotes obvious pain-relieving effect. Some potential complications and their management are:
Bleeding at the needle puncture site: Treat by compressing the puncture site; Soft tissue hematoma next to the needle puncture: Closely monitor and give appropriate treatment; Needle puncture in the wrong organs, or dangerous structures: Treat according to the protocol for each specific case; No effective analgesia: Consider second treatment of osteosarcoma, or surgical consultation. There are many different treatment methods for osteosarcoma, to choose from, it is necessary to prioritize the factors that are simple, accurate, effective and least expensive. In particular, the technique of treating osteosarcoma under the guidance of digital background removal is increasingly widely applied thanks to its outstanding advantages.
Vinmec International General Hospital has applied digital imaging technology to erase the background in examination and diagnosis of many diseases. Accordingly, the digital background removal technique at Vinmec is carried out methodically and in accordance with the process standards by a team of highly qualified medical professionals and modern machinery, thus giving accurate results, contributing to plays an important role in determining disease and disease stage.
