Osteochondral Ridge of Ankle Joint - Anterior Impingement Syndrome of Ankle Joint -

족관절의 골-연골성 골극증 - 족관절 전방 충돌 증후군 -

Purpose : To evaluate the clinical and radiological characteristics of osteochondral ridges of talus and ankle. Materials and Methods : We have analyzed their clinical symptoms and signs, radiologic and CT findings and post-operative results in 17 ankle joints of 14 patients (bilateral in 3), followed them for average 13 months after surgical excision. Results : No definite trauma, but mostly in male after middle age. Their chief complaints are pain on ankle, especially in dorsiflexion or squatting position, and symptom durations are very long, more than average 15 months. Definite diagnosis was made by lateral radiograms of ankle joint. Osteochondral ridges are common in talar neck (10 cases), tibia (4 cases) and both side (3 cases). After excision of osteophytes, all patients gained normal ankle without pain and any limited motion. Conclusions : Anterior impingement syndromes are common in middle aged male, but no definite correlation with sports. Plantar and dorsiflexed lateral radiographs are helpful in definite diagnosis for impingement, and surgical excision is best for treatment.

목적 : 중년기이후의남성에서, 경골 원위 관절면의 전방이나, 거골경부의배부, 또는거골과경골의원위부관절면양측에골극이발생하여족관절배굴장애와통증을호소하는소위, 족관절전방충돌증후군(족관절전방부위골-연골성골극증)의수술경과및방사선학적검사상골극발생부위의특이성을알아보고자한다. 대상및방법 : 1994년3월부터2001년3월까지본대학부속성모병원정형외과에서족관절전방충돌증후군으로진단되어수술가료한14명17족관절(양측3예)를대상으로하였다. 14명17족관절(양측이환3예)중우측이13예, 좌측이4예였고, 14명모두남자였고, 평균연령은47세였다. 명백한족관절외상력은없었으나, 족관절통증(특히배굴시)과쪼그려앉기장애가주소로서평균15개월(4개월$\~$3년11개월) 이상증상이계속되었고, 특별한운동기왕력은없었다. 수술전X-선, 배굴및척굴위측방X-선, CT그리고, 술후X-선과임상과정을최단18주에서최장26개월(평균13개월)까지추적하였다. 결과 : 족관절측부X-선상거골골극이10예로가장많았고, 경골골극이5예(유리골편2례), 그리고거골과경골양측골극형성이2예였다. 14예는족관절전측방도달법을이용하여골극및유리골편을절제하였고, 나머지3예는관절경을이용하였다. 술 후 2주경부터는일상생활보행을허용하였으며, 수술후평균13개월추적조사에서골극이나충돌증후군의재발은없었다. 결론: 족관절전방충돌증후군은운동량이많은중년기남자에빈발하며, 거골경부전방의골극형성이주요원인이었다. 족관절배굴및척굴X-선및CT가진단에도움이되며수술적으로골극을제거하여치료할수있었다.
