Disclosures ... Ballet Soccer Any kicking sport Running downhill •History of ankle sprain Soccer players are at particular risk for anterior ankle impingement syndrome (hence the name “footballer’s ankle”), and ballet dancers are at great risk for posterior ankle impingement (hence the name “dancer’s heel”). These can be categorized as soft tissue or osseous structures, and all potentially causing symptoms during plantarflexion of the dancer's ankle. Foot and ankle injuries are known to be the most injured body part in dancers, and they are more often to be chronic than acute. Soft-tissue impingement lesions of the ankle usually occur as a result of synovial or capsular irritation secondary to traumatic injuries, infection, or rheumatologic or degenerative disease states. Posterior ankle impingement syndrome (PAIS), or "dancer's heel," and tendinopathy of the flexor hallucis longus (FHL tendinopathy), or "dancer's tendinitis," are common in dancers. This explains its common occurrence in individuals involved in activities such as ballet … As the ‘plantar flexion’ movement occurs, the foot and ankle are angled away from the body to their greatest extent, with the ankle … Thirty cases of posterior ankle impingement in 28 patients were treated over a 10-year period (1982–1992). In some cases, ballerinas f Posterior Ankle Impingement 303 with reduced range of plantarflexion can invert their foot with the heel, adopting a varus position (sickling-in) in an attempt to achieve increased height in en pointe positioning. Generally speaking, something is being pinched between the talus and tibia. Other names for this condition are “os trigonum syndrome” and “nutcracker syndrome”. Posterior ankle impingement is especially common in both football players and ballet dancers—due to high loads in plantar flexion.1 Post-traumatic osteoarthritis is another common, and no less important, entity in orthopaedic practice. Many causes of posterior ankle impingement in the dancer have been reported in the literature. Dancers heel (Posterior impingement syndrome) “I have pain in the back of my ankle when I pointe my toe and perform a relevé.” Most common in dancers who are dancing on demi-pointe or pointe (Kadel et al., 2000). Pathoanatomy of posterior ankle impingement in ballet dancers Dance is a high performance athletic activity that leads to great numbers of injuries, particularly in the ankle region. 2004 ; 59 (11):1025–1033. They can get pinched between the joint surfaces and cause pain. foot or an ankle Injury4. Posterior ankle impingement syndrome is a clinical disorder characterized by posterior ankle pain that occurs in forced plantar flexion. Posterior ankle impingement, FHL entrapment. which limits end of range plantar flexion, and one that can be caused by either soft tissue or bony impingement (2). An ankle sprain may cause a tear of the posterior ankle ligaments. 5. Posterior ankle impingement syndrome (PAIS) involves pain at the posterior as- pect of the ankle, due in dancers largely to repetitive hyperplantarflexion. Stenosing Tenosynovitis of the Flexor Hallucis Longus Tendon and Posterior Impingement upon the Os Trigonum in Ballet Dancers William G. Hamilton, M.D. Posterior impingement syndrome refers to pain at the back of the ankle when the foot is plantarflexed (bent downwards) to the maximum, such as when one stands on tiptoe. The studies that are currently being conducted in relation to dancers include those in wellbeing monitoring and mindfulness, posterior ankle impingement, foot pain, hip muscles and movement and cognitive fatigue. 1 T1rho and T2 mapping of ankle cartilage of female and male ballet dancers Posterior ankle impingement syndrome (PAIS), characterised by posterior ankle pain in positions of ankle plantarflexion, has been reported in ballet dancers [1,2,3,4,5] and other athletic and non-athletic populations [6,7,8].Posterior ankle impingement syndrome is an important cause of pain and injury in elite ballet and athletic populations [9, 10]. 23. Posterior impingement occurs in the back of the ankle and is common in ballet dancers who must their foot downward into extreme plantar flexion. The aim of this study is to determine the long-term patient satisfaction after endoscopic treatment and evaluate the recurrence rate of posterior ankle impingement. Os trigonum impingement is a cause of posterior ankle pain in ballet dancers and other athletes who forcibly point their feet. Posterior Ankle Impingement. Pain from both osseous and soft tissue causes may start to occur in the posterior aspect of their ankle. An os trigonum is an accessory bone located posterior to the talus. It is a painful condition. 1 Posterior ankle impingement syndrome refers to a group of abnormal entities that result from repetitive or acute forced plantar flexion of the foot. Soft-tissue impingement lesions of the ankle usually occur as a result of synovial or capsular irritation secondary to traumatic injuries, infection, or rheumatologic or degenerative disease states. ... found by ballet dancers and runners. 51 Hamilton WG. 5. - on X-rays, 31 of 44 feet showed the os trigonum. Kleiger B. The posterior-ankle impingement due to os trigonum can develop after disruption of the os trigonum through a significant acute injury (for example, fracture, fragmentation, and/or pseudoarthrosis). In daily practice, corticosteroid injection is often used to relieve the pain of PAIS, but little has been recorded with regard to its effectiveness. This causes inflammation and pain. Anatomy of the os trigonum. 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. Sometimes the terms are used interchangeably, but you can have posterior ankle impingement due to compression of tissue at the back of your ankle even if you don't have an os trigonum bone. It causes increasing stress to the posterior part of the tibial plafond and the posterior process of the talus. Aim: To describe the magnetic resonance imaging (MRI) features of posterior ankle impingement syndrome (PAIS) in classical ballet dancers. This leaflet aims to give you additional information about your condition and the treatment. The Os trigonum and protruding lateral talar process are two common and well-documented morphological variations associated with posterior ankle impingement in ballet dancers. Mild symptoms occur with motions that require pointing (plantarflexion) of the foot and ankle such as rising to relevé, jumping, kicking a ball, or running depending on gait style. It is recognized most often in ballet dancers who stand in the demi pointe or en pointe … Posterior Ankle Impingement is a condition where an individual experiences pain at the back of the ankle, due to compression of the bone or soft tissue structures during activities that involve maximal ankle plantarflexion motion. Kleiger B. This pathology commonly occurs in ballet dancers and football players. Stenosing tenosynovitis of the flexor hallucis longus tendon and posterior impingement upon the os trigonum in ballet dancers. The primary risk factor for ankle impingement is athletic activity that puts specific kinds of stress on the ankle. The Achilles tendon attaches to the back of the heel bone. 2).The patients were all male, elite athletes in professional level at Turkish Super League with a mean age of … It is classically described in ballet dancers. Secondary treatment options are open or arthroscopic excision of the os trigonum with release of the FHL tendon. Many causes of posterior ankle impingement in the dancer have been reported in the literature. Think this stuff through. Os Trigonum Syndrome (Posterior Impingement), most commonly seen in ballet dancers, can be a frustrating condition to get a handle on. It is called “nutcracker syndrome” not because of its common occurrence in ballet at Christmas-time but because of the way the tissue of the ankle is squeezed at the ankle. Clin Radiol . It is the second most common accessory bone found in the foot, 41 with an overall prevalence ranging from 12.7% to 23.5% in the general population. She is the medical team manager and treats the diverse injuries of the professional ballet dancer. An os trigonum or posterior process fracture was demonstrated radiographically in 63% of these cases, and an intact posterior process was demonstrated in 33%. Other names for this condition are “os trigonum syndrome” and “nutcracker syndrome”. The os trigonum is a small, round,oval or triangular bone with smooth or serrated margins of varied size (typically less than 1cm) located in the back of the ankle joint. This ‘abutment’ occurs when the ankle is positioned in a plantar flexed position (such as is seen in ballet dancers). The extra bone uncommonly develops during adolescence when a part or piece of the talus (ankle bone) does not fuse with the rest of the bone. Posterior ankle impingement. (Sofka 2010; Giannini, Buda et al. Other names for this condition are “os trigonum syndrome” and “nutcracker syndrome”. Ankle impingement is defined as entrapment of an anatomic structure that leads to pain and a decreased range of motion of the ankle and can be classified as either soft tissue or osseous. Peace KA, Hillier JC, Hulme A, Healy JC. Posterior ankle impingement syndrome is an acquired problem related to releve and especially found in dancers who do pointe work. These positions of maximal plantar flexion produce excessive force on the posterior ankle and may result in impingement, pain, and disability. This pain tends to be reproduced when the ankle-foot is brought into full plantar flexion, such as in tendu and particularly pointe work (Luk, Thordarson, and Charlton, 2013). Ballet positions such as en pointe; Bone spurs or arthritic changes in the foot may cause ankle impingement. This may be associated with a fracture in the back of the ankle bone (talus) or an extra bone behind the ankle (os trigonum). The front of the ankle can be subdivided into three compartments, anteromedial, anterior, and anterolateral. Posterior Ankle Impingement: Don’t Get Pinched 11th Annual Sports Medicine Continuing Education Conference Gregory P Witkowski, MD OrthopaedicTrauma and Foot/Ankle Surgery. Running that involves forced plantar flexion, such as downhill running, can put repetitive stress on the posterior aspect of the ankle joint (Van Dijk et al. Posterior ankle impingement is caused by traumatic injury or overuse in dancers, soccer players, runners, and other athletes. Trauma or overuse can be the cause. Posterior ankle impingement syndrome is the term attributed to the clinical disorder characterized by posterior ankle pain that occurs in forced plantar flexion. Introduction. 52. These can be categorized as soft tissue or osseous structures, and all potentially causing symptoms during plantarflexion of the dancer's ankle. In other cases, there is a slight difference in the normal foot and ankle anatomy that eventually leads to posterior ankle impingement. Damage from the past ankle sprain may create too much instability in the ankle. Posterior ankle impingement syndrome (PAIS) refers to a group of pathological entities that result from repetitive plantar flexion of the foot when the foot is in the en-pointe or demipointe position. 2013).It can be caused by overuse, such as ballet dancing or football with repetitive end-range PF, or acute trauma (van Dijk 2006).Although there are many causes for posterior ankle impingement, the symptoms … Posterior ankle impingement syndrome (PAIS) is a common cause of posterior ankle pain that has been classically described in ballet dancers and soccer players [ 1 - 4 ]. These positions of maximal plantar flexion produce excessive force on the posterior ankle and may result in impingement… Posterior ankle … It is normally seen in individuals who partake in sports that involve repetitive or forceful plantar flexion of the foot, such as football, gymnastics and ballet dancing. Posterior ankle impingement is a common cause of pain in ballet dancers. Bone changes include an accessory bone termed the os trigonum or the presence of a stieda process on the talus bone. Know who is at risk for posterior ankle impingement… The research scope is broad and seeks to explore dancer health and wellbeing. However, little data exist regarding its prevalence and relative disease. Gently stretching the ankle joint and lower leg muscles can give pain relief, improve blood flow, allow better joint mechanics, and improve your ability to return to daily activities. posterior ankle block, nutcracker-type impingement, and posterior tibiotalar impingement syndrome.5 More gen-erally, the pathologic contributors can be categorized as either osseous or soft tissue, and, when affected, may all contribute to pain in hyper-plantarflexion.6 presence of an os trigonum is a relatively common The 1, 3, 4, 5 Posterior ankle impingement (PAI) syndrome is one of the impingement syndromes involving the ankle. It is classically described in ballet dancers. It is usually a unilateral phenomenon. Bilateral posterior ankle impingement syndrome has been described but is rare 5. 1. Posterior impingement can also occur in a ballet dancer who has had a previous ankle sprain. It is called “nutcracker syndrome” not because of its common occurrence in ballet at Christmas-time but because of the way the tissue of the ankle is squeezed at the ankle. This comes from repetitive forceful dorsiflexion – pulling the foot and toes upward, toward the shin. This occurs in certain ballet and gymnastic moves and frequently in soccer players who point their toes downward upon striking the ball. 50. Posterior ankle impingement syndrome (PAIS) is a term that describes pain in the back of the ankle when plantar flexing maximally, and sometimes when dorsiflexing. With posterior ankle impingement syndrome, pain, tenderness, and sometimes swelling are generally experienced at the back of the ankle, deep to the Achilles tendon. 1 The os trigonum, which is a normal anatomic variant with a prevalence of 1.7% to 7.7%, usually remains asymptomatic. Anterior ankle impingement occurs from an acute or recurrent ankle sprain causing the ligaments to thicken and get compressed between the bones i.e. 2. 2 Entrapment of soft tissues, bony processes, or unfused ossicles occurs between the posterior tibial plafond and the superior surface of the calcaneum. Posterior ankle impingement can be a result of a number of entities including soft tissue impingement, a prominent bony process or unfused ossicles. This downward movement is called plantar flexion. Are you a dancer with posterior ankle pain, impingement or disability. (2): Posterior ankle impingement syndrome. Chronic entrapment of this tendon can occur resulting from low-lying muscle tissue, impingement from an os trigonum, and incongruity of maximum plantarflexion and dorsiflexion of the ankle and great toe joint resulting in compression of the tendon. PURPOSE: To report the magnetic resonance (MR) imaging findings in seven patients with posterior ankle impingement (PAI) syndrome. 10.1016/j.crad.2004.02.010 The Investigators: Posterior ankle endoscopy/arthroscopy is a technique used to look at and treat problems in the back of the ankle. Symptoms of posterior ankle impingement syndrome, like Achilles tendon problems, include pain behind the ankle. Materials and methods: A retrospective review was undertaken of 25 MRI examinations of the ankle performed on 23 ballet dancers over a 26-month period. 7 synonyms for syndrome: condition, complaint, illness, symptoms, disorder, ailment, affliction. Posterior ankle impingement (back of the ankle injury) is caused by constantly pointing the toes down. In an MRI study of ballet dancers with posterior ankle impingement, the presence of a prominent superior calcaneal tuberosity was associated with impingement symptoms in 64% of cases, and a downward sloping posterior aspect of the tibial plafond showed a relationship to … MATERIALS AND METHODS: Seven patients—three ballet dancers, one badminton player, one soccer player, one hockey player, and one construction worker—who presented with posterior ankle pain were assessed with MR imaging. It must be distinguished from other causes of posterolateral ankle pain. Ankle impingement can become a problem either at the front of the ankle (anterior) or at the back of the ankle (posterior). The main impingement syndromes are anterolateral, anterior, anteromedial, and posterior impingement. All conditions were caused by forced plantar flexion. impingement. However, long-term outcome is unknown. Posterior ankle impingement is a painful condition due to compression of the soft tissues between the posterior edge of the tibia and the calcaneus when the ankle is in plantar flexion. Nonsurgical Treatment You may be asked to rest the ankle for a short time to reduce swelling and pain. The pain may be triggered by an ankle sprain or by the tissue being trapped between the ankle and heel bone. Posterior ankle impingement is a common cause of chronic ankle pain. 8, 41 Despite a relatively high prevalence, the existence of an os trigonum does not typically result in pain or limited ankle plantar flexion motion. Ankle impingement or tendinitis (inflammation of tendons) and metatarsal stress fractures due to overuse are examples of chronic conditions, while ankle sprain remains the most common acute ankle injury. Pivotal Motion Physiotherapy in north Brisbane can provide you with a diagnosis and help manage posterior ankle pain. 51 Hamilton WG. Posterior Ankle Impingement is characterized by pain behind the ankle joint. 2004; 59 … This injury is seen in sports such as dancing (ballet), gymnastics and soccer. The ankle joint is the joint between the lower leg bones (tibia and fibula) and the ankle bone (talus). Gymnasts, foot ballers and ballet dancers generally experience this fairly unique foot and ankle condition. Only 10 of these 27 feet (37%) had a symptomatic os trigonum; - Bone scintigraphic findings of os trigonum: a prospective study of 100 soldiers on active duty . The impingement can be associated with inability to achieve full ankle range of motion when a dancer performs a tendu, or is in a demi- or en pointe position. Are you a dancer with posterior ankle pain, impingement or disability. Posterior ankle impingement is differentiated from insertional Achilles tendonitis and retrocalcaneal bursitis, in that these conditions are more closely associated with the attachment of the Achilles tendon into the heel bone (calcaneus). Ankle impingement syndrome is a syndrome that encompasses a wide range of anterior (anterolateral and anteromedial) and posterior (posteromedial) ankle joint pathology causing painful mechanical limitation of full ankle range of motion secondary to both osseous and soft tissue abnormalities 1).Location of pain is referenced from the tibiotalar (talocrural) joint 2). Posterior ankle impingement syndrome (PAIS) can result from excessive bone formation or soft tissue irritation in the back of the ankle. The tissues and bony structures become compressed in the ankle’s posterior … 2-5 It can become symptomatic after strenuous activity or an injury such as ankle sprain. Foot Ankle Surg 2002;8(1):33-39. It is most common in ballet dancers who must continually rise up on their toes, pointing their foot downward into extreme plantarflexion. 52. Ankle Impingement (Posterior) Posterior ankle impingement is a condition that generates pain in the back of your ankle, especially during activities that require pointing your toes down. 2010-09-01 00:00:00 Dance is a high performance athletic activity that leads to great numbers of injuries, particularly in the ankle region. Our Approach to Dancer's Heel Posterior ankle impingement (PAI) syndrome is one of the impingement syndromes involving the ankle. The aim is to modify the essentials for designing targeted strategies in prevention of Recurrent treatment. Posterior ankle impingement syndrome (PAIS), characterised by posterior ankle pain in positions of ankle plantarflexion, has been reported in ballet dancers [ 1 – 5 ] and other athletic and non-athletic populations [ 6 – 8 ]. Other names for this condition are “os trigonum syndrome” and “nutcracker syndrome”. [ 5] Posterior Ankle Pain After Ankle Sprain: Bony and Soft Tissue Impingement and Flexor Hallucis Longus (FHL) Tenosynovitis 1 March 2021 | Techniques in Foot & Ankle Surgery, Vol. 2010-09-01 00:00:00 Dance is a high performance athletic activity that leads to great numbers of injuries, particularly in the ankle region. Anterior ankle impingement. Nine were professional ballet dancers and 3 were students of advanced ballet schools. Footballers, ballet dancers, gymnasts and fast bowlers (due to the impact on their leading leg), are among those frequently affected by posterior ankle impingement. Antonyms for posterior ankle impingement. Posterior ankle impingement syndrome (PAIS) is commonly defined as posterior ankle pain caused by overuse of ankle motion in the plantarflexion movement. 1995 ). Os trigonum syndrome is the most common cause of posterior ankle impingement. Inflammation and swelling occur due to repetitive stresses at end-range positions of the ankle, such as when one jumps, squats, or descends stairs. One reason for this is the extreme range of ankle motion required of dancers, especially females in classical ballet where the en pointe and demi‐pointe positions are common. MRI studies may show tenosynovitis of the tendon. The cause of the pain is compression or impingement of the bony and soft tissue structures located at the back of the ankle. the tibia and the talus bone. Symptoms result from compression of the talus and soft tissues between the posterior tibia and calcaneum. Posterior Ankle Impingement is a painful condition which an individual experiences at the back part of the ankle as a result of compression of the bone or other soft tissue structures due to excessive plantar flexion of the foot. The usual cause of posterior impingement is The Achilles tendon attaches to the back of the heel bone. The torn pieces can flip inside the joint. Symptoms are exacerbated by pointing the toes in a forced position. Type II accessory navicular. Although there are many causes for posterior ankle impingement, only soft tissue causes will be addressed here, with bony structures expanded on later. AIM OF THE STUDY: The main goal of this research is to understand Posterior Ankle Impingement Syndrome clinical and functional features within the dance practice, especially considering classic ballet. Posterior Ankle Impingement: Don’t Get Pinched 11th Annual Sports Medicine Continuing Education Conference Gregory P Witkowski, MD OrthopaedicTrauma and Foot/Ankle Surgery. It is also commonly seen in the front landing leg of fast bowlers in cricket. Ankle impingement is defined as entrapment of an anatomic structure that leads to pain and decreased range of motion of the ankle, and can be classified as either soft tissue or osseous. Unlike anterior ankle impingement that is common in sportsmen, posterior impingement is commonly seen in dancers. It is most common in ballet dancers who must continually rise up on their toes, pointing their foot downward into extreme plantarflexion. As the dancer rises up on the toes, the talus may be free to slide forward slightly. The os trigonum syndrome with stenosing FHL tenosynovitis is a common cause of posterior ankle impingement, as encountered in our patient. Peace KA (1), Hillier JC, Hulme A, Healy JC. Ankle impingement is defined as a painful mechanical limitation of full ankle range of motion secondary to an osseous or soft-tissue abnormality. A common complaint in ballet dancers, particularly those in pointe shoes is posterior ankle pain. The following taping techniques may be used to provide support for structures located at the back of the ankle or tendons located at the front of the ankle (such as the tibialis anterior tendon), and are particularly beneficial for patients suffering from injuries such as: posterior ankle impingement or tibialis anterior tendonitis). This occurs in people who are their toes often, such as ballet dancers, ice skaters, and gymnasts. A special Posterior Ankle Impingement This is a painful condition of the posterior ankle that is most commonly seen in ballet dancers that bring their ankle frequently into maximal plantar flexion (pointe & demi- … Anterior ankle impingement occurs at the front of the ankle. Shepherd's fracture. Posterior ankle impingement is a common cause of pain in ballet dancers. Posterior ankle impingement syndrome refers to a pathology that is characterised by pain and mechanical limitation in the posterior ankle joint caused as a result of repetitive plantarflexion. Posterior Ankle Impingement - soft tissue. Disclosures ... Ballet Soccer Any kicking sport Running downhill •History of ankle sprain It is a clinical diagnosis in which the patient experiences pain in the hindfoot when the ankle is forced into a plantar-flexed position. Posterior Impingement Surgery (os trigonum) Following your consultation with a member of the Foot and Ankle team you are considering an operation to improve your posterior ankle impingement. Hamilton, W.G., Stenosing tenosynovitis of the flexor hallucis longus tendon and posterior impingement upon the os trigonum in ballet dancers. Posterior impingement syndrome is a condition causing pain at the back of the ankle due to soft tissue or bony compression. Anterior ankle impingement involves pain on the front side of your ankle.
