  • Title: Ground reaction forces on the plantar surface of the foot after talectomy in the myelomeningocele.
    Author: Sherk HH, Marchinski LJ, Clancy M, Melchonni J.
    Journal: J Pediatr Orthop; 1989; 9(3):269-75. PubMed ID: 2723045.
    Abstract:
    Results of talectomies in 19 patients with severe foot deformities secondary to myelomeningocele were evaluated with an average follow-up of 12 years, 7 months. Although an apparently plantigrade foot was usually obtained, talectomy rarely succeeded in distributing weightbearing forces uniformly over the plantar surface. Photoelastic force-plate analysis incorporating three-dimensional contour mapping clearly identified areas of high ground-foot reaction forces (GFRs) and high-pressure gradients. We suggest that such high-pressure areas predispose these patients to neurotrophic ulceration.
