Mother's hand, also known as radial styloid process stenosing tenosynovitis (deQuervain disease), is often affected by novice mothers. If the posture control is poor when holding the baby, using the hand to support the baby's head, repeatedly bending and extending the wrist, and accompanied by resistance abduction of the thumb. It is also common in people who use their thumbs frequently, such as computer workers, pianists, etc. Chronic strain or repeated friction are common causes of inflammation leading to tenosynovitis. The clinical manifestation is pain and tenderness in the wrist, which can affect normal hand movement and worsen when the thumb has a wide range of motion or when the hand exerts force, such as lifting heavy objects.
The extensor tendon on the back of our hand has six chambers, and the inflammation of the tendon sheath or tendon in the first chamber is called radial styloid process stenosing tenosynovitis. The first chamber is located on the radial side of the wrist. The first chamber contains two tendons, namely the extensor hallucis longus tendon and the extensor hallucis brevis tendon. These two tendons can share the same tendon sheath or have their own tendon sheaths (i.e. separated by two sheaths). It is more common for the extensor hallucis brevis tendon to involve a single tendon sheath.
The main auxiliary examination for this disease is ultrasound examination. With the continuous advancement of ultrasound technology and the increasing frequency of probes, ultrasound can clearly identify the structure of tendons and tendon sheaths; And combined with color Doppler blood flow to determine whether the lesion is in the inflammatory phase. The ultrasound manifestation of stenosing tenosynovitis of the radial styloid process is thickening of the first chamber tendon sheath, surrounded by hypoechoic or anechoic echoes; The ultrasound manifestations of tendinitis include thickening and thickening of the tendon sheath, reduced echo, and visible blood flow signals during both active phases.
This disease is mainly treated conservatively. Some drugs that promote blood circulation, remove blood stasis, reduce inflammation and relieve pain can be used, as well as local physical therapy such as hot compress, physical therapy, moxibustion, etc. If the symptoms are obvious and the pain is typical, local closed injection therapy can be adopted, and the effect is also good. Furthermore, it is worth mentioning that with the continuous innovation and development of ultrasound intervention technology, the application of ultrasound technology in the treatment of stenosing tenosynovitis of the radial styloid process has also made rapid progress. Ultrasound can dynamically observe the location and range of the lesion in real time, which can achieve precise visualization treatment. Under ultrasound guidance, drugs can be injected into the tendon sheath or tendon of the lesion. Due to the fact that the anatomical structure of the first chamber tendon sheath varies from person to person, ultrasound-guided treatment can avoid inaccurate treatment sites caused by blind injection. In addition, ultrasound-guided needle knife treatment can accurately relieve local adhesions, relieve pain, and promote disease recovery. In addition to necessary treatment, attention should be paid to keeping warm, avoiding exposure to cold, excessive fatigue, etc.
Due to the fact that stenosing tenosynovitis of the radial styloid process is mainly characterized by pain, it is easy to affect the patient's mood and quality of life, causing low mood. It is important to have a correct understanding of the disease and treatment methods.
