Ilizarov treatment provided satisfactory foot, ankle function in children
Through successful Ilizarov treatment, children with atrophic-type congenital pseudarthrosis of the tibia can obtain satisfactory foot and ankle function at maturity, according to results.
Researchers compared 24 patients who underwent Ilizarov treatment for unilateral atrophic-type congenital pseudarthrosis of the tibia to a control group of 24 participants. Researchers assessed all patients with validated outcome questionnaires, radiographs, physical examination, instrumented motion analysis, including a multisegmental foot model, and pedobarographic measurement.

Results showed a mean score on the AOFAS ankle-hindfoot scale of 89.9 and a mean score on the Oxford Ankle Foot Questionnaire of 42.8 among patients with congenital pseudarthrosis of the tibia. Through motion analysis and pedobarographic measurement, researchers found a slower walking speed due to the short stride length, decreased dorsiflexion in hallux motion, increased hindfoot pronation in the presence of forefoot supination, diminished ankle push-off power, delayed time to heel-rise and decreased forefoot pressure relative to hindfoot pressure on the side affected by congenital pseudarthrosis of the tibia. However, results showed the affected side had a relatively well-preserved sagittal motion of the hindfoot and forefoot. According to results of a subgroup analysis, the tibiofibular synostosis group and the intact-fibula group had no significant differences in terms of clinical outcome scores and most biomechanical parameters. – by Casey Tingle
