Abstract
Purpose:The objective of this study was to define the Os submalleolare as an any ossicles below medial malleolus of tibia and to determine the characteristics of clinical and radiological characteristics and to evaluate results of surgical treatment of Os submalleolare in sports player group.

Material and Methods :Twenty-two patients with Os submalleolare were identified between November, 1, 1998 and June, 30, 202.

Results:The mean age was 18.3 years. All patients were male and soccer players comprised 71%(20 cases). Associated disease were 8 cases(29%) of chronic ankle instabilities, on case(4%) of anterior impingement syndrome and one(4%) of plantar fascitis. The most common clinical symptom was pain during walking and sports activity and sign was tenderness around medial malleolus. Only simple radiograph could reveal presence of ossicle and differentiate with acute fracture. If symptom and sign obscured. Bone scan(7 cases) and MRI(3 cases) identify causes of pain and tenderness. As a surgical treatment, all bony fragment caused symptom and sign were eliminated and medial collateral ligament was reattached meticulously. Associated chronic ankle instability were present, modified Brostrom procedure was done simultaneously. On follow-up, The symptomatic pain were wholly disappeared at average 2.2 months (1-6 months) after operation. On one year follow-up, all patients have been daily life without any complaints and have gone back to the game within three months.

Conclusions:Os submalleolare have relatively rare incidence in sports players and most common clinical symptom and sign is tenderness on medial malleolar area of ankle, can be diagnosed both physical examination and plain X-ray filem. As a treatment, Removal of ossicle and reattachment of MCL could obtain excellent or good results.
