Peroneal tenosynovitis is a condition that affects the peroneal tendons, which are located on the outside of the ankle. These tendons play an important role in stabilizing the foot and ankle during movement. Tenosynovitis refers to inflammation of the synovium, a protective sheath that surrounds the tendons and allows them to glide smoothly. When this sheath becomes inflamed, it can lead to pain, swelling, and limited mobility.
The main causes of peroneal tenosynovitis include repetitive activities that strain the tendons, such as running, jumping, or participating in sports that involve frequent ankle movement. Trauma, such as an ankle sprain or direct impact to the area, can also contribute to the development of this condition. In some cases, underlying conditions like rheumatoid arthritis or gout may increase the risk of peroneal tenosynovitis.
The symptoms of peroneal tenosynovitis typically include pain along the outside of the ankle and foot, swelling, tenderness, and a sensation of snapping or popping. The pain may worsen with activity and improve with rest. If left untreated, the inflammation can lead to the development of scar tissue, further restricting the movement of the tendons.
Diagnosis of peroneal tenosynovitis is usually made through a combination of physical examination and imaging studies, such as X-rays or magnetic resonance imaging (MRI). Treatment options for this condition include both conservative and surgical approaches. Initially, the RICE (rest, ice, compression, elevation) protocol may be recommended to reduce pain and swelling. Non-steroidal anti-inflammatory drugs (NSAIDs) may also be prescribed to alleviate inflammation.
Physical therapy is often recommended to strengthen the muscles around the ankle, improve flexibility, and promote healing. Orthotic devices, such as ankle braces or shoe inserts, may be used to provide support and relieve stress on the tendons. In cases where conservative measures do not provide sufficient relief, surgical intervention may be considered to remove scar tissue or repair damaged tendons.
