Objectives/Interrogation: The medial femoral condyle (MFC) flap has become a popular option for small bone defects or calcitrant nonunions. The potential of chimeric design also provides flexibility and versatility for bone reconstruction. We aim to describe outcomes after MFC flap treatment of phalangeal or metacarpal bone defects.

Methods: A retrospective chart review was performed on all patients undergoing Free MFC flaps by between March 2012 and August 2018. Patient demographic data intraoperative, and postoperative data were collected.

Results: We identified 12 patients for inclusion (8 phalangeal bone and 4 metacarpal reconstructions) treated with the MFC flap for diagnoses including bone defect (8) bone tumor (2), congenital deformity (1) and nonunion (1). There were 7 males and 5 females, aged from 4 to 54 y/o (28.8 years in average). Follow-up time was from 2 to 34 months (10.6 months in average). With regards to the flap design, there were 3 chimeric osteocutaneous flaps, 7 periosteocancellous flaps, 2 periosteal flaps. Bone union was achieved in all the patient at 5 to 18 weeks postoperatively (8.1 weeks in average). There were no intraoperative flap complications or donor site morbidity.

Conclusions: Phalangeal or metacarpal bone reconstruction using the MFC flap results in a fast bone regeneration and union with minimal donor morbidity.
