The optimal surgical and reconstructive strategies for chondromyxoid fibroma (CMF) of the metatarsal bones remain controversial. This study examined the outcomes of en bloc resection followed by fibular strut allograft reconstruction in 9 patients with aggressive or recurrent metatarsal CMF.
Methods
Nine patients were included in this retrospective case series. Indications for this approach included thin cortex, cortical breakdown, or local recurrence. Outcomes were recurrence, radiographic union, limb function, and surgical complications.
Results
At a median follow-up of 8 years, no local recurrence was recorded in this series. Radiographic union at both host-allograft junctions was achieved in 8 of 9 patients. The median Musculoskeletal Tumor Society score was 30. The median Toronto Extremity Salvage Score was 96. Complications were infrequent and manageable.
Conclusion
En bloc resection followed by fibular strut allograft reconstruction appears to provide durable local tumor control and encouraging functional outcomes in patients with aggressive or locally recurrent metatarsal CMF.
