Five patients with giant cell tumor of the proximal fibula were treate
d with intralesional excision of the lesion, preservation of the peron
eal nerve, and reconstruction of the lateral collateral ligament. At m
inimum 24-month follow-up there have been no local recurrences. Four p
atients exhibit normal function of the peroneal nerve and one has grad
e 4 strength of the muscles innervated by this nerve. No patient demon
strated varus instability. Marginal excision with nerve preservation a
nd reconstruction of the ligament is a worthwhile procedure for treatm
ent of this relatively uncommon lesion. (C) 1996 Wiley-Liss, Inc.
