Abstract
Toe phalanx transplantation is a well-established technique for addressing bony deficiency in the reconstruction of hypoplastic digits in patients with congenital differences of the hand. Prior studies have commented on varying degrees of donor-site morbidity, although assessment of morbidity with validated outcome scores is lacking. This study seeks to evaluate donor-site morbidity after toe phalanx harvest using validated outcome measures. We identified all children who underwent free, nonvascularized toe phalanx transfer to the hand at our institution from 2001 to 2011. We administered the Oxford Ankle Foot Questionnaire for Children (OXAFQ-C) and the Foot and Ankle Ability Measure (FAAM) to all patients, scaling results according to published scoring instructions. Thirty-six patients with 83 toe phalanx transfers were able to be contacted, with a mean follow-up of 5.3 years (range, 18 months-11.2 years). The results of the OXAFQ-C showed mean scores of 99.96% (Physical), 100% (School and Play), and 96.01% (Emotional). The FAAM mean scores were 99.08% (Sports) and 99.17% (Activities of Daily Living). There were no lower extremity complications during the study period. In contrast to varying degrees of donor-site morbidity reported in the current literature, this study demonstrates that toe phalanx harvest causes almost no measurable lower extremity morbidity or dysfunction over the mid- to long-term. Therapeutic IV.
