“…Haglund's deformity is caused by bony overgrowth of the posterior calcaneus and is considered a developmental anatomic variant [7][8][9]. This retrocalcaneal exostosis has been implicated in a variety of painful entities, most commonly Achilles tendinosis and retrocalcaneal bursitis [7][8][9]. In our case, however, the concomitant presence of opposing calcaneal and talar developmental variants resulted in impingement syndrome.…”

“…Biomechanically, repetitive forced plantar flexion of the foot results in chronic injury to the aforementioned posterior elements. Ballet dancers, athletes in jumping sports and professional football players, like in our case, are at increased risk of developing this syndrome due to prolonged and continuous plantar flexion [7][8][9]. The patient's history and physical examination can suggest the correct diagnosis.…”

“…If there is failure of fusion, an os trigonum is formed, which articulates with the talus through a synchondrosis [3][4][5][6]. Haglund's deformity is caused by bony overgrowth of the posterior calcaneus and is considered a developmental anatomic variant [7][8][9]. This retrocalcaneal exostosis has been implicated in a variety of painful entities, most commonly Achilles tendinosis and retrocalcaneal bursitis [7][8][9].…”

“…In our case, however, the concomitant presence of opposing calcaneal and talar developmental variants resulted in impingement syndrome. The soft tissues that may be injured in posterior ankle impingement syndrome include the posterior articular capsule, the posterior talofibular, intermalleolar, and tibiofibular ligaments and the flexor hallucis longus tendon [6][7][8][9]. Biomechanically, repetitive forced plantar flexion of the foot results in chronic injury to the aforementioned posterior elements.…”

“…The initial treatment of posterior ankle impingement syndrome is conservative by means of physiotherapy. If this should fail, arthroscopic or open debridement results in symptomatic relief and in improvement of ankle function along with restoration of range of motion [7][8][9][10].…”

Pathoanatomy of posterior ankle impingement in ballet dancers

et al. 2010

View full text Add to dashboard Cite

Dance is a high performance athletic activity that leads to great numbers of injuries, particularly in the ankle region. 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. These positions of maximal plantar flexion produce excessive force on the posterior ankle and may result in impingement, pain, and disability. Os trigonum and protruding lateral talar process are two common and well-documented morphological variations associated with posterior ankle impingement in ballet dancers. Other less well-known conditions, of both bony and soft tissue origins, can also elicit symptoms. This article reviews the anatomical causes of posterior ankle impingement that commonly affect ballet dancers with a view to equipping healthcare professionals for improved effectiveness in diagnosing and treating this pathology in a unique type of athlete.

Prevalence and distribution of sesamoid bones and accessory ossicles of the foot as determined by digital tomosynthesis

et al. 2017

We previously reported that digital tomosynthesis (DTS) is a reliable tool for evaluating bony structures of the hand. The current study aimed to identify the prevalence and distribution of sesamoid bones and accessory ossicles of the foot using DTS and to compare the results to those of conventional radiography (CR). Foot images (DTS, 213; CR, 44) of 213 patients taken at a tertiary hospital were retrospectively reviewed. Sesamoid bones were identified in the metatarsaophalangeal (MTP), distal interphalangeal (DIP) and interphalangeal (IP) joints of the great (I), second (II), third (III), fourth (IV), and fifth (V) toes. Accessory ossicles were observed in the midfoot and hindfoot. The mean number of sesamoid bones and accessory ossicles was 3.9 ± 1.3 for the left foot and 3.7 ± 1.0 for the right foot on CR; and 3.9 ± 1.4 for the left foot and 3.9 ± 1.3 for the right foot on DTS. Sesamoid bones were observed in MTP I (100%), MTP II (5%), MTP III (2%), MTP IV (2%), MTP V (14%), and IP (68%) on CR. Sesamoid bones were observed in MTP I (100%), MTP II (8%), MTP III (1%), MTP IV (2%), MTP V (25%), and IP I(65%) on DTS. Among accessory ossicles, the most common bone identified was os tibiale externum (23% on CR and 33% on DTS) andos peroneum (14% on CR and 21% on DTS), and os trigonum (32% on CR and 0.5% on DTS). DTS was useful for finding sesamoid bones and accessory ossicles, although there were some limitations in observing the hindfoot. Clin. Anat. 30:1072-1076, 2017. © 2017 Wiley Periodicals, Inc.
