What is a Stieda process?
The Stieda process is an elongation of the lateral tubercle of the posterior process of the talus (Fig 1). It is larger than the medial tubercle and is considered the most variable aspect of hindfoot anatomy. 2, 3, 4, 5. This process is the insertion point of the posterior talofibular ligament.
What is prominent posterior process of the talus?
Posterior ankle impingement caused by a prominent talar trigonal process, either a prominent posterior process of the talus (Steida’s process) or discrete separate os trigonum is an often under-recognized cause of hindfoot pain.
What is posterior impingement?
Posterior ankle impingement is an uncommon problem that results from activities that utilize excessive pointing of the toes (or straightening of the ankle), most commonly dancing and ballet. Posterior refers to the back side of the ankle.
What causes posterior ankle impingement syndrome?
Posterior ankle impingement results from compression of structures posterior to the tibiotalar and talocalcaneal articulations during terminal plantar flexion. Pain is caused by mechanical obstruction due to osteophytes and/or entrapment of various soft tissue structures due to inflammation, scarring or hypermobility.
Does ankle impingement require surgery?
Anteromedial impingement does not always require surgery, however, there are times when the bone spurs at the bottom of the tibia present a situation where surgery is recommended. When we discuss surgery, as we do not perform it, it is always best to bring in a surgical opinion.
How do you treat posterior ankle impingement?
Posterior Ankle Impingement Syndrome: Treatment
- Nonsteroidal anti-inflammatory medications (NSAIDS). Oral medications that decrease inflammation and pain.
- Immobilization. A cast, splint, boot or brace immobilizes the ankle for a short period of time.
- Physical therapy.
- Corticosteroid injections.
How long does posterior ankle impingement take to heal?
How long Does Posterior Ankle Impingement Take to Heal? It can take up to 12 weeks to fully recover from posterior ankle impingement – whether you have surgical or non-surgical treatment.
Where is the posterior ankle?
The anatomy of the posterior aspect of the ankle is a key factor in the occurrence of PAIS. The posterior ankle region comprises the soft-tissue structures situated behind the tibiotalar joint and the calcaneus.
Does posterior ankle impingement disappear?
How long does ankle impingement take to heal?
Recovery time after an anterior ankle impingement can vary widely depending on the extent of the injury. Typically, it takes four to six weeks before athletes can get back to their normal activities. Recovery time can take longer for severe cases.
Stieda process. Stieda process (not to be confused with a Pellegrini-Stieda lesion) refers to an elongated lateral tubercle of the posterior process of the talus 1,3. It is often considered an anatomical variant. It forms from fusion of a secondary ossification center at the posterolateral aspect of the talus with rest of the talus…
What does SP stand for in Stieda?

What is the pathophysiology of A stieda process?
A Stieda process per se is not pathological, however its presence increases the risk of the posterior ankle impingement syndrome. 1. Berman Z, Tafur M, Ahmed SS, Huang BK, Chang EY.
