Osteochondral lesion of humeral head as an associated lesion is reported in some cases but, not considered tobe a main origin of the symptoms. We found the similar features of osteochondral lesion on humeral head in threecases of internal impingement syndrome irrespective of conservative treatment for over three months and reportgood results obtained from arthroscopic debridement and microfracturing for these lesions with a review of theliteratures.
