Abstract
Free nonvascularized toe phalangeal transfer is an established surgical option for the reconstruction of hypoplastic digits. This study assessed long-term morbidity in the feet using this technique. We reviewed 40 children treated between 1991 and 2007 by free nonvascularized toe phalangeal transfer. The diagnosis was digital hypoplasia resulting from symbrachydactyly in 33 cases, constriction ring syndrome in 3 cases, thumb hypoplasia in 3 cases, and perinatal subclavian venous thrombosis in 1 case. The patients were followed up after surgery for a mean of 10 years (range, 3-19 y). The Oxford Ankle Foot Questionnaire was administered to patients and families to assess patient symptoms and patient and parental satisfaction. We assessed toe length ratio, the presence of visible deformity, and distal hypoplasia of the donor toes clinically and radiographically. Emotional problems related to foot appearance were common. We also found functional problems with footwear in some patients. All patients had floppy unstable toes with visible deformity. Increasing foot deformity was seen with growth, which led to deterioration in foot aesthetics, particularly where multiple donor toes had been harvested. We identified distal and middle phalangeal and metatarsal hypoplasia in the donor toes. Donor site morbidity for free toe phalangeal transfer is greater than previously documented. This should be considered during surgical decision making for reconstruction of hypoplastic digits. Preoperative counseling should include discussion regarding possible consequences of phalangeal harvest on donor toes and options for donor site reconstruction. Long-term follow-up of the donor site is essential to accurately assess results. Therapeutic III.
