Background:
Amputation of the abnormal segment seems to be the reference standard treatment for the surgical management of macrodactyly of the foot in children. Our objectives here were to detail the surgical strategies according to the cause, anatomical characteristics, and static or progressive nature of the macrodactyly and to evaluate the long-term clinical outcomes.
Hypothesis:
Conservative treatment can be an option in the management of static macrodactyly of the foot in children.
Material And Methods:
We retrospectively included 24 feet in 19 patients seen consecutively. There were 12 primary and 12 secondary types. The macrodactyly was static in 9 cases and progressive in 15 cases. The treatment consisted in either conservative procedures or amputation of the segment. All patients completed the Oxford Ankle Foot Questionnaire for Children (OxAFQ-C) to evaluate their quality of life, shoe wear issues, and satisfaction with their treatment.
Results:
Mean age at first surgery was 5.8 years (range, 0.5-11.5) and the mean interval between two procedures was 2.3 years (range, 0.3-5.5). Mean number of procedures per foot was 2.2 par pied (range, 0-7). All 9 static forms were managed conservatively. Amputation was performed in 11 of the 15 progressive forms. The mean number of procedures was significantly higher in the progressive forms (4.1 vs. 1.5/pied; p=0.006). Two patients died during follow-up. The remaining 17 patients, with 22 affected feet (primary and secondary in 11 cases; progressive in 14 cases and static in 8 cases) were re-evaluated. Mean follow-up was 9.4 years (range, 2.7-20.6). The final OxAFQ-C score was 46/60 (range, 18-58). Of the 17 patients, 86% would be willing to repeat the same surgical procedures and 77% were satisfied with their treatment at last follow-up. We found no differences between the groups managed with amputation and with conservative treatment regarding quality of life, satisfaction, or shoe size difference.
Conclusions:
Conservative treatment deserves a place in the treatment of static macrodactyly of the foot in children. Regarding amputation of the segment in progressive forms, it is important to reassure the patients and parents about the expected results but also to inform them about the risk of requiring repeat surgical procedures.
Level Of Evidence:
IV, retrospective study.
