Experiments in coding clinical information: an analysis of clinicians using a computerized coding tool

In 50 congenital clubfeet (in 28 children aged 62-126 months) operated on with subtalar release from dorsolateral and posteromedial approach isometric strength of flexors, extensors, pronators and supinators was assessed with tensometry. All the muscular groups showed decreased momentum if compared to normal foot. The smallest deficit was observed in plantar flexors. Better results were accompanied by greater muscular strength, but statistically significant relation existed between strength of dorsal flexors and the quality of result. Postoperative calcaneus position did not influence the strength of dorsal or plantar flexors of the foot. Additional lengthening of FHL and FDL decreased the strength of plantar flexion.
