Objective To analyze and discuss the clinical therapy and treatment outcomes of congenital gigantism of the foot. Methods The clinical documents of 2 cases of congenital gigantism of the foot were retrospectively analyzed. The 2 patients＇ average age was 20 years old. All the deformities were found at birth. The cases of multiple toes involved were more than that of single toe, and the cases of tibial toe involved were more than that of fibular toe. The forefoot was enlarged. All the phalanges involved and partial metatarsal bones were enlarged. Marked increase in subcutaneous fat was found in all the cases in the operation, which infiltrated the interossei and articular capsules. The appearance of the nerves and their branches in the foot were normal and fatty infiltration was not discovered. Corrective osteotomy and reconstruction of tendon check point were performed on the 2 patients, who were followed up for 1 year. The appearance and function of the limb were observed. Results The 2 patients were satisfactory with the postoperative function and appearance. Conclusions According to the age, clinical classification, degree of pathological changes and limb function, the 2 cases of the digital gigantism of the foot are in progress. To save the function, we choose corrective osteotomy and reconstruction of tendon check point. The function and appearance of the 2 patients＇ toes get improved after the surgery. The blood supply, feelings and activities of the toes are well during the follow-up.
