Definition/Description[edit | edit source]
Peroneal tendonitis is a condition that can be acute or become chronic whereby there is irritation to one or both peroneal tendons with subsequent degeneration and inflammation.
Clinically Relevant Anatomy[edit | edit source]
The peroneus longus and peroneus brevis muscles reside in the lateral compartment of the lower leg and are innervated by the superficial peroneal nerve. The m. peroneus longus arises from the head and proximal two-thirds of the lateral surface of the body of the fibula and the origine of the peroneus brevis is located on the distal two-thirds of the lateral surface of the body of the fibula, medial to the Peroneus longus. The peroneus longus tendon turns medially between the cuboid groove and the long plantar ligament and inserts onto the plantar surface of the base of the first metatarsal and the lateral aspect of the medial cuneiforms. The peroneus brevis tendon continues directly to its insertion onto the tuberosity of the fifth metatarsal.[1]
The actions of the peroneus longus and brevis are plantarflexion and eversion.
Epidemiology /Etiology[edit | edit source]
Peroneal tendonitis is common in running athletes, young dancers, ice skaters and sports requiring frequent change of direction or jumping such as basketball.[1][2] Contributional factors to the development of peroneal tendonitis are tight calf muscles, inappropriate training, poor foot biomechanics such as overpronation of the foot or excess eversion of the foot, inappropriate footwear and muscle weakness of the m. peroneus longus.[2] Other causes include severe ankle sprains, fractures of the ankle or calcaneus, and peroneal tubercle hypertrophy.[1]

Diagnostic Procedures[edit | edit source]
A thorough subjective and objective examination from a physiotherapist can be sufficient to diagnose peroneal tendonitis. Diagnosis may be confirmed with an MRI scan or ultrasound investigation showing oedema[3]
Patients with this condition usually experience pain behind and distal to the lateral malleolus during activities putting stress on the peroneal tendons(lateral running, fige-8 running), or following these activities or following a rest period, especially upon waking in the morning. There may be associated swelling in the acute phase. There will also be pain when testing resisted foot eversion.[1][2]
The pain associated with peroneal tendonitis tends to be of gradual onset which progressively worsens over weeks or months with the continuation of aggravating activities.[1]
You can isolate the peroneal muscles from each other when you use the peroneus longus and brevis tests and you can also evaluate their strenght by muscule testing of the peroneus longus and brevis.

Medical Management
[edit | edit source]
Patients diagnosed with peroneal tendinitis can be treated with non steroidal anti-inflammatory medication , physical therapy(see below), and rest.[1][2][4]
If nonoperative treatment is ineffective, an open tenosynovectomy is recommended.[1][2][4] Postoperatively patients are made nonweightbearing during the first 2 weeks. The, they are placed in a short leg weightbearing cast or boot. Range of motion and strengthening activities (eccentric exercise) are started 2 to 4 weeks after surgery.[1]
Also the use of lateral heel wedges can help managing mild cases peroneal tendinitis.[4]
The use of corticosteroid injections is not recommended. [1][2][5]
Physical Therapy Management (D)[edit | edit source]
Treatment for peroneal tendonitis includes a program of stretching, strengthening, mobilisation and manipulation, icing, ankle bracing or taping during contact sports.[1][2][5]
There is fair evidence for the use of eccentric exercise.[5]
The use of a biomechanical ankle platform (BAPS), deep tissue friction massage, ultrasound electric stimulation can also be included in the physical therapy. [1][5]
Also extracorporeal shock wave therapy (ESWT),acupuncture are used to treat tendinopathy. But there is only limited evidence from studies for these treatments. [5]
