The peroneus brevis tendon inserts in the 5th metatarsal bone on the exterior of the foot. Any strain or rupture of the tendon can develop at the area of insertion.
The peroneus brevis muscle plantar is responsible for flexing and everting the foot. Its tendon links to the 5th metatarsal on the exterior of the foot. The end of the 5th metatarsal is felt as a bony prominence on the exterior of the foot. It is important to note that the peroneus brevis muscle can tighten among runners especially those who run on roads.
The peroneal tendon ruptures after a traumatic injury such as an ankle sprain. As for acute injuries, it includes avulsions or tears.
What are the indications of a peroneus brevis tendon injury?
The symptoms include pain over the protuberant bony region on the exterior of the foot. The pain is likely to occur abruptly after twisting or abrupt forceful movement of the ankle.
Bruising and swelling can also occur while there is pain while walking. The pain is usually aggravated when stressing the tendon by everting the foot or turning the sole outwards, especially against resistance.
Apply an ice pack as soon as possible after the injury. It should be done for 10 minutes every hour and lower the frequency but a minimum of 3 times in a day is recommended. Cold works by reducing the pain and inflammation as well as limit swelling that can delay the healing process.
Adequate rest is vital for at least 48 hours as the acute phase of the injury passes. In case activity is continued with limping, it will delay the healing process. Once the acute phase has passed, mild stretching can be performed if pain is not triggered.
Anti-inflammatory medications such as ibuprofen can minimize the pain and inflammation in the initial phases.
In some cases, laser treatment or ultrasound are also used to reduce the pain, inflammation and promote healing.
Once the injury has fully healed, a rehabilitation program for the foot and ankle must be started which includes stretching and strengthening exercises.
