Abstract
Intraosseous lipoma of the calcaneus is a benign lesion formed by mature adipose tissue.
When the lesion is symptomatic, the most frequent presentation is localized pain and
soft tissue swelling. Because these lesions can regress spontaneously, conservative
treatment methods are recommended. Operative excision is mostly required for painful
lesions and pathologic fractures. The data from 14 patients with calcaneal intraosseous
lipoma, who had undergone surgery in our clinic, were evaluated retrospectively. Using
Milgram’s classification system, 9 lesions were classified as stage 1, 4 as stage
2, and 1 as stage 3. All lesions were occupying 100% of intracalcaneal cross-section
in the coronal plane and >30% in the sagittal plane of magnetic resonance imaging
sections. The mean preoperative visual analog scale score was 5.29 ± 1.14 (range 4
to 7), and the mean postoperative visual analog scale score at the last follow-up
visit was 1.14 ± 0.36 (range 1 to 2), which was significantly better (p < .01). The mean Maryland foot score at the last follow-up visit was 97.71 ± 2.02
(range 95 to 100). The mean American Orthopaedic Foot and Ankle Society Ankle-Hindfoot
scale score was 97.86 ± 2.11 (range 94 to 100) at the last follow-up visit. The differences
between the pre- and postoperative values were statistically significant (p < .01). No recurrence had been detected within a median follow-up period of 84 months.
Operative management of symptomatic lesions related to intraosseous lipoma of the
calcaneus provides better results compared with the preoperative state.
