Outcome analysis, including patient and parental satisfaction, regarding nonvascularized free toe phalanx transfer in congenital hand deformities.
The therapy for congenital hand malformations, especially in symbrachydactyly and constriction ring syndromes, is challenging. Between 1975 and 1995, 20 children with congenital hand deformities underwent reconstruction by 56 nonvascularized free toe phalanx transfers. The average age at initial surgery was 4.8 (range, 0.5 to 22) years. Retrospectively, the children were examined after an average of 3.5 (range, 1.5 to 17.6) years for function of the hand, transplanted phalanx growth, assessment for the epiphyseal plate, and assessment for psychologic performance with their parents. Donor-site morbidity was determined according to measured growth deficit, observing the child's gait, and toe function. In the younger patients (up to 1.5 years), the grafts were well tolerated and showed good growth and only few resorptions. In the age group from 1.5 to 4 years, the grafts showed no growth. In the age group older than 4 years, the grafts were mostly resorbed. The clinical reexamination revealed in most cases only passive motion in the joints, but the function of the hand was improved, with only few problems of the donor site. Most patients and their parents reported a positive effect of the phalanx transfer.
