Ballet dancers frequently stand on the tips of their toes in the en pointe and demi pointe positions, resulting in compression of the posterior structures of the ankle during repeated plantar flexion of the foot, producing the talar compression syndrome. This mechanism may result in posterior block or impingement of an os trigonum or Stieda's process. When the dancer attempts to force the foot into plantar flexion, the os trigonum or the Stieda's process may be impinged between the calcaneus and the posterior edge of the tibia. Pain and tenderness are localized at the posterolateral aspect of the ankle behind the peroneal tendons. In nondancing members of the population, these conditions are usually asymptomatic. It is the requirement of the classical dance for a well-pointed foot that produces symptoms. We are reporting up to 7 years' followup of six professional ballet dancers in whom we removed the os trigonum for symptomatic talar compression syndrome, caused by the trauma of the en pointe position of toe dancing. Two patients had bilateral operations. All six patients returned to professional dancing within a few months and remained asymptomatic. The anatomy of this condition is reviewed, as well as the diagnosis and treatment.
芭蕾舞演员经常以足尖站立或半足尖站立的姿势跳舞，在足部反复跖屈时会导致踝关节后部结构受到挤压，从而引发距骨挤压综合征。这种机制可能导致三角骨或施蒂达氏突的后部受阻或撞击。当舞者试图强行将足部跖屈时，三角骨或施蒂达氏突可能会被挤压在跟骨与胫骨后缘之间。疼痛和压痛位于踝关节后外侧、腓骨肌腱后方。在非舞蹈人群中，这些情况通常无症状。正是古典舞蹈中对足部完美尖立的要求导致了症状的出现。我们报告了6名职业芭蕾舞演员长达7年的随访情况，他们因足尖舞蹈姿势造成的创伤导致距骨挤压综合征而接受了三角骨切除术。2例患者接受了双侧手术。所有6例患者在几个月内恢复了职业舞蹈，且无症状。本文对该病症的解剖结构、诊断和治疗进行了综述。
