What are the effects and risks of corticosteroid injections for tennis elbow?
Tennis elbow, also known as lateral epicondylitis, is a condition in which corticosteroid injections (commonly referred to as "block injections") may provide benefits such as pain relief and improved range of motion, but also carry risks including subcutaneous tissue atrophy and infection. A detailed analysis is as follows:
I. Benefits
1. Pain Relief
This condition is usually caused by aging or prolonged wrist activities. Patients may experience severe elbow joint pain due to stimulation from inflammatory factors. Block injections can exert anti-inflammatory effects, thereby helping to alleviate pain.
2. Improved Range of Motion
Patients with lateral epicondylitis often have restricted movement due to intense discomfort in the elbow joint during physical activity. By reducing this discomfort, block injections can help improve mobility limitations.
II. Risks
1. Subcutaneous Tissue Atrophy
The hormonal components in block injections may irritate subcutaneous tissues, potentially causing temporary subcutaneous atrophy. This side effect can generally be relieved through local massage.
2. Infection
If proper care is not maintained during or after the injection procedure, bacteria may enter the injection site and cause infection. In such cases, patients may be prescribed medications such as levofloxacin hydrochloride capsules, erythromycin ointment, or amoxicillin capsules, to be used according to medical advice.
It is recommended that patients undergo block injection treatment for lateral epicondylitis only at正规 medical institutions.
