In Nov. 1992 we started endoscopic curettage without bone grafting
for enchondromas in hand and have got good results. We now perform this
procedure for other benign bone tumors. The purpose of this paper is to evaluate the
results of endoscopic curettage without bone grafting for cystic lesions in
calcaneus. Eight patients with cystic lesion in calcaneus
underwent endoscopic curettage without bone grafting at our hospital from 1998 to
2008. The average age at surgery was 18.5 years-old and the mean follow-up period
was 35.4 months. There were four solitary bone cysts, two aneurysmal bone cysts
and two chondroblastomas. Usually two portals were made with several millimeter
skin incisions and fenestrations of cortex bone. Thorough curettage of the tumor was
performed using curettes and electrical shaver under endoscopic
visualization. Good visualization through arthroscopy was obtained in all
patients. New bone formation was observed by roentgenogram in all the patients 3.3
months after surgery averagely in spite of no bone grafting. There was no infection
and no recurrence.The advantages of this procedure
are as follows; 1. Less surgical insult, 2. No need of bone grafting, 3. Easy to
evaluate the remnant of curettage due to magnified observation, 4. Less blind areas
than conventional method, 5. No need of immobilization, 6. No need of postoperative
rehabilitation with early recovery of function. We conclude that this procedure is one
of the good choices for the treatment of cystic lesions in calcaneus.
